Description

Solar Water Heater Automatic Control Device

The utility model relates to an automatic control device for the water in and out of a solar water heater.

The existing solar water heater inlet and outlet control device mainly adopts the float type control switch, but it generally has the following defects: the control water tank is too large in size, the mechanism is complicated, there are many faults, and the service life is short. Searching for the above-mentioned defects has not yet found an effective technical solution related to the utility model.

The purpose of this utility model is exactly the automatic control device of a kind of novel solar water heater design for above-mentioned technical defect.

In order to achieve the above object, the utility model adopts the following technical solutions:

The utility model comprises a box body, in which a cock valve is arranged, one end of the cock valve is connected with the water inlet pipe, and the other end is connected with the water outlet pipe; The ends of the handles are respectively hinged to a water cup, the bottom of the water cup is provided with a discharge hole, a tension spring is connected to the tank cover, and the other end is connected to a handle, and a pair of positioning rods are set on the valve body of the cock to cooperate with the above handle. , the position of the positioning rod is flush with the axis of the cock valve, and an overflow pipe and a control pipe are arranged on the box body, and their positions are respectively set at the corresponding positions when each water cup is turned to the level, that is, the overflow pipe (water tank ) can be poured into a water cup, and when the water is full, the valve core will rotate and close the cock under the action of gravity and spring; at the same time, the other water cup (empty cup) will be turned to the horizontal position and positioned by the positioning rod to control the direction of the pipe. The water cup is filled with water, and the valve core is rotated and the stopcock is opened under the action of gravity and spring.

Due to the adoption of the above technical solution, the utility model has the advantages of simple structure, reliable performance, durability, low cost, etc., and is the most ideal water inlet and outlet control device for solar water heaters at present.

In order to illustrate the utility model in more detail, the following drawings provide a preferred embodiment of the utility model.

Description of drawings:

Fig. 1 is the main sectional view of the utility model;

Fig. 2 is the top view of Fig. 1;

Fig. 3 is a schematic diagram of the installation of the utility model in a solar water heater.

As shown in Figures 1 and 2, a box cover 1a is provided on the box body 1, and a control pipe joint 16 is connected to the bottom of the box body 1, and a check valve 15 is arranged on the joint, which is located at the bottom of the inner cavity of the box body 1, so that Let the accumulated water in the box 1 flow out, the upper end of the joint 16 is connected with the control pipe 2, the upper end is connected with a positioning pipe 5, and a water inlet pipe 14 is connected at the bottom of the box, and the end extending into the box is connected with a tee 4 , the left end of the three-way 4 is provided with a one-way valve 3, the right end of the three-way 4 is connected with a cock valve 7, the right end of the cock valve is connected with the water outlet pipe 11 and fixed on the box body, the box cover 1a is connected with an overflow pipe 8, and the cock valve The spool shaft 7c of 7 connects two handles 9 and 12 that are 90 degree angles each other, the handle ends are respectively hinged with water cups 10, 13, and the bottom of the water cups is provided with overflow holes 10a, 13a, and two valve bodies are arranged on the cock valve body. Two positioning rods 7a, 7b, a tension spring 6 is connected on the case cover, and its other end is connected on the handle 9, so that the handle 9 is positioned by the positioning rod 7a when the handle 9 is in the horizontal position on the right side, and now the overflow pipe 8 is just aiming at the water cup Within the range of 10, when the through hole of the spool shaft 7c reaches the through hole of the valve body, the cock valve is in an open state; if the water cup 10 is filled with water, it rotates around the spool shaft 7c under the action of gravity, and the water cup 13 rises, finally in the water cup 10. Under the action of extension spring 6 and gravity, handle 9 is in a vertical state, handle 12 is in a horizontal state and is positioned by positioning rod 7b. 7c through hole turns 90 degrees, then stopcock closes. If pouring water in water cup 13 from positioning pipe, can carry out and above-mentioned opposite course of action. The working principle of the utility model in the solar water heater is shown in Figure 3. Close the valves d and a, open the valves c and b, water will be added to the water heater tank f through the valve c and the opened cock valve 7, and the water will overflow after the water is full. The water flowing out of the pipe 8 flows into the water cup 10, and under the action of gravity, the handle of the water cup 10 is rotated 90 degrees from the horizontal position to the vertical position, so that the valve 7 is closed to stop adding water to the water tank, and then the water in the water cup 10 is drained from the bottom. The water flows out from the hole, and then flows out from the one-way valve 15 and valve b at the bottom of the box body 1. After the valve 7 is closed and the valve d is opened, the water in the pipelines of valves c and 7 can be emptied by the shower head e (the one-way valve 3 is Drain the intake pipe), thus preventing the water pipe from freezing. When taking hot water, close valve b and open valve a, water flows out of control pipe 2 from valve a, and fills water cup 13 (the dotted line position). In this way, the hot water can flow out from the shower head through the valve 7 and the open valve d. After the hot water flows out, the valve a can be closed, and the valve b can be opened. 15 and valve b flow out, emptying the water pipe, thus preventing the water pipe from freezing.
