Find more information at Enersol Solar Control System page. In order that the invention may be more clearly understood, reference will now be made to the accompanying drawings which illustrate a preferred embodiment of the invention by way of example, and in which: FIG. 5 and 6. The valve has a valve body which defines four chambers disposed end to end. This valve is generally indicated at 104 in FIG. Motor 60 incorporates a speed reduction gear box 114 disposed externally of the motor support casing 62 and having an output shaft 116 which extends into the casing. Check valve 82 comprises a domed valve element 148 having a depending stem 150 which is a free sliding fit in a fixed collar 152 so that the valve element is vertically movable as indicated by the arrow 154 in FIG.
According to the invention, the valve includes a valve body which defines a valve chamber, flow and return chambers, and a drain-down chamber. It will be seen that insert 140 is of generally cylindrical shape and part of the sealing face 138 is visible inside one end of the cylinder. 8.

You plug the controller into the chlorinator, then the pump plugs into the piggy back. info. 5. Part 263045, Goldline / Hayward 3-Way Actuator for automatic solar or pool control. You need to have your pool pump running during the day. Two limit switches 128 and 130 are mounted inside casing 62 for co-operation with a disc 132 integrally formed on rod 58 inside casing 62. Further, when the valve is in use, heat loss through the solar collectors of the system due to thermal syphoning is avoided because the collectors will automatically drain down in the event that the valve is operated to cause the water to bypass the collectors. Since the collectors themselves form no part of the present invention, they will not be described in more detail. In practice, the power supply circuit to motor 60 will be a relatively sophisticated automatic control circuit including temperature sensors for automatically operating valve 44 in accordance with temperature conditions prevalent in the system and with ambient temperatures. With a dual digital display, customizable features and full system diagnostic LEDs, AquaSolar TC provides the same reliable solar pool heating and control capabilities of the AquaSolar, but also includes an integral time clock for 24-hour control of the pool's main pump and filtration system. Further, while the preceeding description is directed primarily to solar heating systems for swimming pools, it is to be understood that the invention is not limited in this regard and that the control valve may be used in any liquid-type solar heating system. Our objective is to make your pool experience worry and hassle-free. A control valve of the form provided by the invention is generally indicated at 44 and is connected in the primary circulation circuit formed by the lines 32 and 34 and the pump filter as shown. For example, as indicated above, the float controlled valve arrangement employed in the drain-down chamber 56 is not essential if gravity can be employed to drain water from chamber 56 and return it to the pool. Line 38 is connected to a filter having an output line 42. The only thing I do not like is the incoming water temperature sensor. However, in the event that water accumulates in chamber 56, the float will be lifted, causing the valve member 110 to move away from opening 92 and allow the suction effect of the pump to remove the water from chamber 56. When the temperature cools towards the end of the day, the controller will automatically turn the valve back so the water will stop running through the solar and will go straight back to the pool the normal way. 2.

Reviewed in the United States on June 18, 2018. service center location, advanced 1) will allow air to enter the solar collectors at this time so that the water can drain freely. A recess 98 is formed in one face of rod portion 96 and is spaced inwardly from the outer end of that portion by an extent such that the recess is disposed in inlet 90 when the primary valve member 94 is in its first position. When the collectors are not in operation, the water is delivered directly from the filter outlet line 42 to the pool return line and the valve is also designed to automatically drain the collectors at this time so as to avoid the problems discussed above involved with allowing the collectors to remain full of water while water from the pool is bypassing the collectors. I opted to purchase a sensor that threads into the drain hole of the pump instead. Profile, Create a Pool Help other Direct Pool Supplies users shop smarter by writing reviews for products you have purchased. at least one solar collector having flow and return lines and vacuum breaker means for admitting air to said collector during draining of water therefrom; a reservoir containing liquid to be heated; means defining a main liquid circulation circuit and having an outlet through which liquid can be removed from said reservoir and an inlet through which liquid can be returned to the reservoir; a pump in said circuit for conveying liquid from said outlet to said inlet; a control valve coupled in said circuit and including: (a) a valve body which defines: a valve chamber having an inlet communicating with said pump for receiving liquid to be heated, and first and second outlets; flow and return chambers communicating respectively with said first and second valve chamber outlets, said flow chamber having an outlet coupled to said solar collector flow line through which liquid can be delivered to the collector, and said return chamber having an inlet coupled to said solar collector return line, said return chamber additionally having an outlet coupled to said circulation circuit inlet through which liquid received from said collector can be returned to the reservoir; a drain-down chamber having an inlet for receiving liquid drained from said collector and an outlet through which drained liquid can be returned to the reservoir, said inlet communicating with said flow chamber; (b) check valve means associated with said return chamber inlet and adapted to prevent reverse flow of liquid in said inlet; (c) valve means including a primary valve member disposed in said valve chamber and movable between first and second positions in which said member closes said first and second valve chamber outlets respectively; valve actuating means operable from externally of said chambers and adapted to move the valve member between its said positions; and a secondary valve member associated with said drain-down chamber inlet and operable simultaneously with said primary valve member to close said inlet when the primary valve member is in its said second position, and to open said inlet when the primary valve member is in its said first position. Read them several times and understand them before starting if a DIY project, especially if you do not have experience in plumbing, pool/spa or electrical fields. BIO-ENERGY SYSTEMS, INC. A CORPORATION OF NEW YO, Free format text: The weight of the float normally maintains valve member 110 in a position in which it closes outlet 92. 1). 2 but to close the inlet under the effect of water flowing in the opposite direction. Go Green with a little help from the sun. The valve member is shown in its second position in FIG. The drain-down chamber has an inlet for receiving liquid drained from the collector, and an outlet through which drained liquid can be returned to the reservoir. If valve member 94 is displaced to close the first outlet 68 of valve chamber 50 (by axially displacing rod 58) incoming water will be diverted from the valve chamber 50 through its outlet 70 and into the return chamber 54. Enjoy automatic maximization of solar heat collection and reliable, accurate performance. A great way to automate your solar pool heating! Then when the temperature rises the controller will automatically divert the water to the roof. It automatically maximizes solar heat collection by actuating a 24V valve when there is solar heat available. The other end of the tube is connected to the suction side of pump 36. Wiring is fairly easy, however setting the limits on the valve adjustment takes some practice. Its like using an air conditioner or furnace without a thermostat. Member 94 is integrally mounted on the valve operating rod 58 so that longitudinal displacement of this rod will cause the valve member to move between its two positions as will be described. Find more information at Enersol Solar Control System page. In order that the invention may be more clearly understood, reference will now be made to the accompanying drawings which illustrate a preferred embodiment of the invention by way of example, and in which: FIG. 5 and 6. The valve has a valve body which defines four chambers disposed end to end. This valve is generally indicated at 104 in FIG. Motor 60 incorporates a speed reduction gear box 114 disposed externally of the motor support casing 62 and having an output shaft 116 which extends into the casing. Check valve 82 comprises a domed valve element 148 having a depending stem 150 which is a free sliding fit in a fixed collar 152 so that the valve element is vertically movable as indicated by the arrow 154 in FIG. According to the invention, the valve includes a valve body which defines a valve chamber, flow and return chambers, and a drain-down chamber. It will be seen that insert 140 is of generally cylindrical shape and part of the sealing face 138 is visible inside one end of the cylinder. 8. A valve as claimed in claim 3, wherein said valve actuating means comprises a rod mounted for axial movement along said axis of the valve body, wherein said primary valve member is carried by said rod for axial movement therewith between its said first and second positions, and wherein said secondary valve member is disposed at an end portion of said rod adjacent said drain-down chamber inlet. If that valve should leak, the collectors will be gradually pressurized by water flowing in the reverse direction past the check valve because the pinch valve is closed. All AquaSolar controllers automatically divert the water flowing between your pool's filter and heater and route it through solar thermal collectors. Where the valve is connected to a suction line, there is no need to rely on gravity for drainage. Suction line 46 in fact takes the form of a length of plastic tubing which is solvent welded over sleeve 102 but is not shown in FIG. Reviewed in the United States on June 9, 2016.
FIG. A system as claimed in claim 11, wherein said control valve further comprises float control valve means in said drain-down chamber associated with said chamber outlet and adapted to normally close said outlet but to open the outlet in response to a predetermined level of liquid in said chamber; and wherein the system further comprises a suction line connected to said drain-down chamber outlet and to a suction side of said pump whereby liquid draining into said drain-down chamber can be drawn out of said chamber and into the pump when said float control valve means is open. You plug the controller into the chlorinator, then the pump plugs into the piggy back. info. 5. Part 263045, Goldline / Hayward 3-Way Actuator for automatic solar or pool control. You need to have your pool pump running during the day. Two limit switches 128 and 130 are mounted inside casing 62 for co-operation with a disc 132 integrally formed on rod 58 inside casing 62. Further, when the valve is in use, heat loss through the solar collectors of the system due to thermal syphoning is avoided because the collectors will automatically drain down in the event that the valve is operated to cause the water to bypass the collectors. Since the collectors themselves form no part of the present invention, they will not be described in more detail. In practice, the power supply circuit to motor 60 will be a relatively sophisticated automatic control circuit including temperature sensors for automatically operating valve 44 in accordance with temperature conditions prevalent in the system and with ambient temperatures. With a dual digital display, customizable features and full system diagnostic LEDs, AquaSolar TC provides the same reliable solar pool heating and control capabilities of the AquaSolar, but also includes an integral time clock for 24-hour control of the pool's main pump and filtration system. Further, while the preceeding description is directed primarily to solar heating systems for swimming pools, it is to be understood that the invention is not limited in this regard and that the control valve may be used in any liquid-type solar heating system. Our objective is to make your pool experience worry and hassle-free. A control valve of the form provided by the invention is generally indicated at 44 and is connected in the primary circulation circuit formed by the lines 32 and 34 and the pump filter as shown. For example, as indicated above, the float controlled valve arrangement employed in the drain-down chamber 56 is not essential if gravity can be employed to drain water from chamber 56 and return it to the pool. Line 38 is connected to a filter having an output line 42. The only thing I do not like is the incoming water temperature sensor. However, in the event that water accumulates in chamber 56, the float will be lifted, causing the valve member 110 to move away from opening 92 and allow the suction effect of the pump to remove the water from chamber 56. When the temperature cools towards the end of the day, the controller will automatically turn the valve back so the water will stop running through the solar and will go straight back to the pool the normal way. 2.
