Description

Technical Field

[0001] This invention patent relates to a solar water heater controller, and more particularly to an automatic control valve for a solar water heater. Background Technology

[0002] The most pressing problem that solar water heaters need to solve is: A large amount of water leaked out when filling the water tank because the valve was left open: water leakage problem.

[0003] Every time hot water is used, a lot of cold water must be drained first: a problem with waiting for hot water.

[0004] Water pipes freeze or break in winter, making it impossible to use the hot water in the tank: a hibernation problem.

[0005] There are many existing solar water heater control products, most of which are combinations of solenoid valves, electric heating internal circulation, electric heating tape antifreeze, float switches and mixing valves. These products mostly use electricity, and wires need to be laid indoors and outdoors. Because they work in humid environments, there are safety hazards, and the installation is complicated and costly, which seriously hinders the promotion and use of solar water heaters.

[0006] My patent: The automatic control system for solar water heaters without power supply has not yet met design requirements, especially the automatic shut-off function. Patent No.: ZL2015 20375152.X. Summary of the Invention

[0007] To solve the problems of water leakage, heat waiting time, hibernation, and especially automatic shutdown of solar water heaters, a multi-functional control valve for solar water heaters without power supply was invented. The technical solution adopted by this invention to solve its technical problem is: It consists of an indoor control unit consisting of a power-free multi-functional control valve and an outdoor controlled unit consisting of a hydraulic remote control valve. (The outdoor hydraulic remote control unit has been separately patented.) The indoor control section features a power-free multi-functional control valve. The valve body includes a function conversion chamber FQ2, a water volume display chamber BQ, an inlet connector JT1, an inlet / outlet connector JT2, a shower connector JT3, a remote control overflow connector JT4, and a drain connector JT5. The function conversion chamber FQ2 contains a ceramic stationary valve plate CF3 with holes 1-3, 1-4, 2, and 3, and an overflow hole 4-1 communicating with the inside of connector JT4. The ceramic moving valve plate CF4 has arc-shaped grooves H3 and H4, and a hexagonal rod on the other side. The pressure cap YG2 has external threads and a circular through hole. The handle SB has a hexagonal blind hole NK2. The water volume display chamber BQ contains meter mounting holes 2-1 and 2-2.

[0008] The power-free multi-functional control valve has two sliding rods SX1 inside the valve body, two springs TH2 inside the water tank SX, two sliding rod holes SX2 inside the water tank SX, an inclined body XM outside the water tank SX, a quick-opening valve chamber FQ1, a ceramic fixed valve plate CF1 installed inside the chamber, a pair of holes 1-1 and a pair of holes 1-2 on the valve plate, an vent hole PK, an arc-shaped groove H1 and an arc-shaped groove H2 on the ceramic moving valve plate CF2, a small spring TH1 installed in the center hole ZK, a round rod G2, a hexagonal hole NK1 on the plumb bob QZ, and a round hole at the bottom of the arc-shaped body on both sides in the middle, with a round rod G1 installed in the round hole. The overflow pipe 4-2 contains a one-way valve DF1 and a one-way valve control mechanism DF1-1. Beneficial effects

[0009] By combining the original patented mixing chamber and function conversion chamber into a single function conversion chamber FQ2, and changing the structure of directly controlling automatic shutdown with the water tank to a structure that uses the inclined surface SX of the water tank to start the plumb bob action QZ, the reliability of the operation has been greatly improved.

Detailed Implementation

[0011] Water tank filling: Connector JT1 of the power-free multi-functional control valve to the tap water supply; connector JT2 to the inlet and outlet water pipes of the solar water heater; connector JT3 to the shower head; and connector JT4 to the inlet of the overflow control pipe.

[0012] Lift the lifting rod TG, which is hinged to the lead weight QZ, upwards. The lead weight QZ passes through the internal hexagonal hole NK1, causing the ceramic valve plate CF2 with a hexagonal rod to rotate 60 degrees with the center of the cavity FQ1. At this time, the circular rod G1 in the lower circular hole of the quick-opening valve lead weight QZ and G2 in the central hole ZK are on the same center line. The spring TH1 in the central hole ZK pushes G1 and G2 to move a distance, and the lead weight QZ is locked by the circular rod G2. The arc grooves H1 and H2 on CF2 connect the holes 1-1 and 1-2 on CF1. Rotate the handle SB upwards by 180 degrees. At this time, the hole 3 on CF3 and the overflow hole 4-1 that communicates with the inside of the connector JT4 are closed. The one-way valve control mechanism DF1-1, which is linked with SB, opens the one-way valve DF1 installed in the overflow pipe 4-2. Tap water enters CF1 through JT1 via CF1-1, then through H1 and H2 on CF2, and through CF1-2 via CF3-1-3 and CF3-1-4. It then enters CF3-1 through the arc groove H3 via CF4-2 (hole 2 is connected to the inside of 2-1, and hole 2-2 is connected to the inside of connector JT2. The meter can rotate in both directions and is connected to the system through valve chamber BQ-2-1 and 2-2). Through holes 2-1, 2-2, JT2, and inlet / outlet pipes, the water is injected into the water tank of the outdoor water heater.

[0013] Automatic shutdown: After the water heater tank is full: overflow water enters connector JT4 through the overflow remote control pipe. Since the overflow hole 4-1, which is connected to the inside of JT4, is closed, the one-way valve DF1 installed in the overflow pipe is opened by the one-way valve control mechanism DF1-1. The overflow water can only enter the small water tank SX through the overflow pipe 4-2. After the water tank is filled with the set amount of water, it overcomes the elastic force of the spring TH2 and moves down along the slide rod SX1. After the water tank SX moves down a certain distance, the one-way valve DF2 inside the water tank is opened, and all the overflow flows through the drain connector JT. 5. During the evacuation, the inclined plane XM on the water tank pushes G1, G2, and TH1 to move a distance. The circular rod G2 releases the constraint on the plumb bob QZ. Under the action of gravity, QZ rotates 60 degrees synchronously with CF2. At this time, the arc groove H1 on the moving valve plate disconnects the passage between hole 1-2 and the lower hole of 1-1. H2 connects 1-2 with the evacuation hole PK. The residual water in the inlet and outlet pipes is emptied through PK and the drain connection JT5. As a result, there is no water inside the inlet and outlet pipes and the overflow remote control pipe, and the pipes will not freeze in winter.

[0014] Use hot water: With the handle SB in the vertical 0-degree position, the valve plate CF4 is installed in the valve cavity FQ2 via the pressure cap YG2. The hexagonal rod on CF4 is tightly fitted with the internal hexagonal hole NK2 on SB. The arc groove H3 on CF4 connects holes 1-3 with holes 2 and 3; H4 on CF4 connects 1-4 with 4-1. Pressurized water enters the overflow remote control pipe through 1-4 and overflow hole 4-1, forming a pressure. Under the action of pressure, the one-way valve DF1 closes the overflow pipe 4-2 and opens the hydraulic remote control valve (which is claimed separately). Hot water in the water tank enters the shower head for use through the inlet and outlet pipes, connectors JT2, 2-2, 2-1, 2, mixing temperature control zone H3, 3, and JT3. The water temperature can be adjusted by rotating the handle SB clockwise or counterclockwise; rotating it 45 degrees clockwise only dispenses hot water, and rotating it 45 degrees counterclockwise only dispenses cold water.

[0015] Shut down and empty the remaining water in the pipeline: Rotate SB 90 degrees clockwise. At this time, H4 on CF4 disconnects holes 1-4 and 4-1, causing the overflow remote control pipe to lose pressure and the upper ends of the inlet and outlet pipes to be closed. The remaining water in the pipes enters the shower head through connectors JT2, 2-2, 2-1, 2, H3, and 3. The remaining water in the overflow remote control pipe enters the shower head through 4-1 and H3, 3. As a result, the remaining water in the inlet and outlet pipes and the overflow remote control pipe is used up. The next time water is used, the inlet and outlet pipes will directly discharge the hot water in the water tank. Since the pipes are empty, they are not easily damaged by freezing in the cold winter.

Claims

1. Water tank filling: Lift the lifting rod TG, which is hinged to the lead weight QZ, upwards. The lead weight QZ passes through the internal hexagonal hole NK1, causing the ceramic valve plate CF2 with a hexagonal rod to rotate 60 degrees with the center of the cavity FQ1. At this time, the circular rod G1 in the lower circular hole of the quick-opening valve lead weight QZ and G2 in the central hole ZK are on the same center line. The spring TH1 in the central hole ZK pushes G1 and G2 to move a distance, and the lead weight QZ is locked by the circular rod G2. The arc grooves H1 and H2 on CF2 connect the holes 1-1 and 1-2 on CF1. Rotate the handle SB upwards by 180 degrees. At this time, the hole 3 on CF3 and the overflow hole 4-1 that communicates with the inside of the connector JT4 are closed. The one-way valve control mechanism DF1-1, which is linked to SB, opens the one-way valve DF1 installed in the overflow pipe 4-2. Tap water enters CF1 through JT1 via CF1-1, then through H1 and H2 on CF2, and through CF1-2 via CF3-1-3 and CF3-1-4. It then enters CF3-1 through the arc groove H3 via CF4-2 (hole 2 is connected to the inside of 2-1, and hole 2-2 is connected to the inside of connector JT2. The meter can rotate in both directions and is connected to the system through valve chamber BQ-2-1 and 2-2). Through holes 2-1, 2-2, JT2, and inlet / outlet pipes, the water is injected into the water tank of the outdoor water heater.

2. Two: Automatic shutdown: After the water heater tank is full: Overflow water enters connector JT4 through the overflow remote control pipe. Since the overflow hole 4-1, which communicates with the inside of JT4, is closed, the one-way valve DF1 installed in the overflow pipe is opened by the one-way valve control mechanism DF1-1. Overflow water can only enter the small water tank SX through the overflow pipe 4-2. After the water tank is filled with the set amount of water, it overcomes the elastic force of spring TH2 and moves down along the slide rod SX1. After the water tank SX moves down a certain distance, the one-way valve DF2 inside the water tank is opened, and all overflow flows through the drain valve. When the flow connector JT5 is emptied, the inclined body XM on the water tank pushes G1, G2, and TH1 to move a distance. The circular rod G2 releases the constraint on the plumb bob QZ. Under the action of gravity, QZ rotates 60 degrees synchronously with CF2. At this time, the arc groove H1 on the moving valve plate disconnects the passage between hole 1-2 and the lower hole of 1-1. H2 connects 1-2 with the emptying hole PK. The remaining water in the inlet and outlet pipes is emptied through PK and the drain connector JT5. As a result, there is no water inside the inlet and outlet pipes and the overflow remote control pipe.

3. Three: Using hot water: With the handle SB in the vertical 0-degree position, the valve plate CF4 is installed in the valve cavity FQ2 via the pressure cap YG2. The hexagonal rod on CF4 is tightly fitted with the internal hexagonal hole NK2 on SB. The arc groove H3 on CF4 connects holes 1-3 with holes 2 and 3; H4 on CF4 connects 1-4 with 4-1. Pressurized water enters the overflow remote control pipe through 1-4 and overflow hole 4-1, forming a pressure. Under the action of pressure, the one-way valve DF1 closes the overflow pipe 4-2 and opens the hydraulic remote control valve (which is claimed separately). Hot water in the water tank enters the shower head for use through the inlet and outlet pipes, connectors JT2, 2-2, 2-1, 2, mixing temperature control zone H3, 3, and JT3. The water temperature can be adjusted by rotating the handle SB clockwise or counterclockwise; rotating it 45 degrees clockwise only dispenses hot water, and rotating it 45 degrees counterclockwise only dispenses cold water.

4. Four: Shut down and empty the remaining water in the pipeline: Rotate the handle SB clockwise 90 degrees. At this time, H4 on CF4 disconnects holes 1-4 and 4-1, causing the overflow remote control tube to lose pressure and the upper ends of the inlet and outlet water pipes to be closed. The remaining water in the pipes enters the shower head through connectors JT2, 2-2, 2-1, 2, H3, and 3. The remaining water in the overflow remote control tube enters the shower head through 4-1 and H3, 3. As a result, the remaining water in the inlet and outlet water pipes and the overflow remote control tube is used up. The next time you use water, the inlet and outlet water pipes will directly discharge the hot water in the water tank.
