Description

Water inlet and outlet control device for solar water heater

The utility model relates to a water inlet and outlet control device for a solar water heater, which relates to a water inlet and outlet control device for a water tank of a solar water heater.

When the hot water tank of the existing solar water heater is filled with water, people need to take care of it. They are afraid that the water pressure will be low, the water will not be filled, the water will be full, overflow, or there will be backflow; the water pipe will freeze in winter; the utilization rate of hot water is low. high.

The purpose of this utility model is to propose a solar water heater inlet and outlet water control device, which can realize automatic, semi-automatic and non-automatic, semi-automatic and non-automatic, and emptying of the inlet and outlet water pipes according to the changes in the amount of solar radiation in each season control.

The solar water heater water inlet and outlet control device of the utility model is to open two circular openings at the bottom of the water tank to install the water inlet and outlet two-way control devices respectively, and connect with the tap water pipe and the water pipe to form the water inlet and outlet control of the solar water heater water tank together. device.

Accompanying drawing 1 is the structural representation of this solar water heater inlet and outlet water control device;

Accompanying drawing 2 is the view of two-way braking wheel;

Accompanying drawing 3 is one of embodiment of the water inlet control device of this solar water heater inlet and outlet water control device;

Accompanying drawing 4 is one of embodiment of the water outlet control device of this solar water heater inlet and outlet water control device;

In the figure: a solar water heater water tank water inlet control device composed of 2 floats, 3 float links, 4 float link collars, 5 water inlet cone spools, 6 marble spools, and 7 water inlet pipe interfaces, and It consists of 8 high-position water outlet cone valve cores, 9 head metal tubes, 10 silicone rubber tube fixing rings, 11 pressure reducing holes, 12 silicone rubber tubes, 13 support rod fixing frames, 14 corrugated silicone rubber tubes, 15 support rods, and 16 supports Rod collar, 17 installation and sealing base, 18 water outlet pipe interface, 19 driving cable, 20 two-way brake wheel, 21 spool connecting rod, 22 low-level water outlet cone spool, 23 one-way valve, 24 The solar water heater composed of the support seat The water outlet control device of the water tank is sealed and plugged into the water tank 1 from two holes with a diameter of 47 mm on the bottom respectively, and its water inlet pipe interface 7 is connected with the water inlet switch of the 35 tap water pipe and the emptying valve of the tap water inlet pipe of the 36 tap water pipe. connection; its outlet pipe interface 18 is connected with 37 reverse water injection valve, 38 hot water valve, 39 shower nozzle, 40 main water outlet valve,

The marble spool of the water inlet two-way control valve can rise under the impetus of the water filling water pressure to enter the water tank, and it can also be lowered by its own weight to close the water inlet pipe interface to prevent the water in the water tank from flowing backwards; its water inlet two-way control valve The upper water inlet conical valve core is connected with the floating ball to form a whole. Its average specific gravity is less than 1 but greater than 0.8. When the water level rises to the water level line, a small buoyancy force is generated to make the conical valve rise to realize closing and stopping. Water intake; when the water level drops below the water level line, the float ball and the water inlet cone valve core connected with it will descend, and the water can continue to enter. One of its embodiments is that after the diameter of the floating ball of the water inflow control device is reduced, a horizontal columnar floating ball is added above the floating ball.

The high water outlet cone spool and the low water outlet cone spool of the two-way water outlet control valve are respectively installed at the upper and lower openings of the "C"-shaped pipe to form controllable high and low water outlets. The two-way brake wheel is installed axially. On the support base 24, the water outlet state of the high and low water outlets is changed by the brake wheel driving device. The two-way brake wheel is similar to the rotating wheel of the electric light pull switch, and two axially perpendicular angles of cam A and cam B are added; The high water outlet cone spool is socketed with the cam A of the two-way brake wheel through the spool connecting rod, and the low water outlet cone spool is socketed with the cam B of the two-way brake wheel through the valve core connecting rod; The driving wheel can make the two-way brake wheel rotate 90°, open the upper valve and close the lower valve at the same time, and can also open the lower valve and close the upper valve at the same time. The one-way water outlet valve 23 is installed on the "C" shaped pipe and the On the outlet pipe 18 between the pipes. The drive cable that drives the two-way brake wheel is realized by the lifting of the corrugated silicone rubber tube of the drive device. The corrugated silicone rubber tube is sleeved on the drive pipe; ordinary rubber tubes can also be used to replace the corrugated silicone rubber tubes according to the embodiment of the water outlet device, and the upper part of the metal tube with pressure reducing holes is covered with a silicone rubber tube and fixed The lower part of the head metal tube is connected with the corrugated silicone rubber tube head and fixed with the silicone rubber tube fixing ring. The support rod fixed on the head metal tube and its lower end is inserted into the support rod collar to drive the pull wire. One end is connected to the metal pipe of the head, and the other end is connected to the two-way brake wheel. Open the reverse water injection valve 37 of the tap water pipe, and the corrugated silicone rubber pipe will stretch upward quickly, and the two-way brake wheel will be driven to rotate 90°, that is, the water outlet of the high and low water outlet cone valve core will be switched to open and close once, when the pressure is too high The decompression hole can be automatically decompressed.

Water pipe is connected water inlet pipe interface 7 by water pipe switch 35 and 36. The running water pipe is connected with the water outlet pipe interface 18 through the reverse water injection valve 37 of the running water pipe and the main water outlet valve 40, and the reverse water injection valve 37 also plays the role of the water temperature regulating valve of the shower nozzle simultaneously.

The utility model can respectively realize automatic, semi-automatic and non-automatic three water inlet and outlet states in seasons with strong sunshine, poor seasons and seasons that need antifreeze, and can empty the water in the outlet pipe and the water inlet pipe, to prevent the pipes from freezing. The conversion of different operating states is realized by the pressure difference caused by reverse water injection. The whole device does not need electricity, which is safe and convenient.
