Abstract

The utility model is an automatic water supply device for a solar water heater, which includes a water tank. The bottom of the water tank is provided with a water tank water inlet connection pipe. The bottom end is connected with the plunger. The plunger is a cylinder with one end large and the other end small. There is a hole through the center and a plunger sleeve outside the plunger. The upper end of the plunger sleeve is connected to the water tank inlet. There is a plunger sleeve on the wall to connect the water port. The plunger sleeve on the plunger sleeve corresponds to the plunger. This device is mainly driven by the floating ball that moves up and down with the change of the water volume in the water tank. Do the action of closing and opening the plunger sleeve water inlet, so as to achieve the purpose of automatic water supply, and solve the problem that the water supply of solar water heaters has changed from manual control to mechanical automatic control.

Description

Solar water heater automatic water supply device

technical field

The utility model relates to an automatic water supply device for a solar water heater, which can automatically and timely supply water for the solar water heater.

Background technique

The water inlet connection pipe of the existing water heater tank is directly connected to the water pipe of tap water, and there is a manual control valve in the room, that is to say, the water volume in the solar water heater tank needs to be manually controlled, which is inconvenient and easy to cause water shortage or overfill.

Contents of the invention

The purpose of the utility model is to provide an automatic water supply device for a solar water heater that can replenish the water in the water tank of the solar water heater without manual control.

The utility model is realized through the following technical solutions: an automatic water supply device for solar water heaters, including a water tank, the bottom of the water tank is provided with a water tank water inlet connecting pipe, and the feature is that the floating ball is installed in the water tank, and the floating ball handle connected with the floating ball It goes out from the water inlet of the water tank, and its bottom end is connected with the plunger. The plunger is a cylinder with a large end and a small end. There is a hole through the center of the plunger. There is a plunger sleeve outside the plunger. The upper end is connected with the water inlet connection pipe of the water tank, and the side wall is provided with a plunger sleeve water inlet connection pipe, and the plunger sleeve water inlet connection on the plunger sleeve water inlet connection pipe corresponds to the plunger.

The utility model has simple structure and low cost. After the original solar water heater is assembled with the device, the return pipe is omitted, so that the cost of the whole solar water heater will not increase. The important thing is that the water supply is automatic and timely, full but not overflowing.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing.

Description of drawings

Fig. 1 is a structural representation of the utility model.

Description of drawings:

1 float, 2 float handle, 3 plunger sleeve, 4 plunger, 5 water tank water inlet connection, 6 plunger sleeve water inlet connection, 7 plunger sleeve water inlet, 8 channels, 9 water tank.

Detailed ways

Referring to FIG. 1 , the utility model includes a float 1 installed in a water tank 9 , and the other end of a float handle 2 connected to the float 1 is connected with a plunger 4 . The structure of the plunger 4 is a cylinder with one end large and the other end small (as shown in the figure, the plunger 4 is a thin upper structure and a thicker bottom), the center has an up and down through hole 8, and a plunger sleeve 3 is arranged outside the plunger 4 , the upper end of the plunger sleeve 3 is fixed on the water tank inlet pipe 5, the side wall is provided with a plunger sleeve inlet pipe 6, the plunger sleeve inlet 7 on the plunger sleeve nozzle 6 and the position of the plunger 4 Correspondingly, the water pipe of running water is installed on the plunger sleeve and is inserted on the water port connecting pipe 6.

During use, the float 1 moves up and down with the change of the water volume in the water tank 9, and this movement becomes the action of closing the plunger 4 and opening the plunger to insert the water port 7 through the float handle 2, thereby completing the effect of automatic water supply.

The specific working principle is as follows:

When the amount of water in the water tank of the solar water heater decreases, the water level will drop, and the floating ball in the water tank will drop with the water level due to its own weight. Gap increases between, has opened plunger sleeve water inlet, and tap water just enters water tank, makes the water level in the water tank rise. When the water level rises to a certain position, under the action of the floating ball that rises with the water level, the plunger moves upward to close the plunger sleeve inlet, and the water supply stops.

When the plunger moves up and down, there will be pressure reduction and pressure increase in the space between the lower part of the plunger and the bottom of the plunger sleeve. This phenomenon will affect the tightness of the plunger to close the water inlet of the plunger sleeve and increase the movement of the plunger. resistance. In order to solve this unfavorable factor, a hole 8 is drilled in the center of the plunger, so that the upper and lower parts of the plunger are connected to balance the pressure.
