Embodiment Construction

[0012] see figure 1 As shown, a bottomless inner container 3 is fixed in the casing 1, and its outside is covered with a coverless movable container 5, and there is a certain gap between the inner container 3 and the movable container 5. The movable container is positioned in the casing 1 through two positioning brackets 7-1, 7-2, and the movable container 5 can slide up and down relative to the positioning bracket and the casing along its axial direction. The bottom of the movable container is provided with a drain 6. The inner container 3 is fixed on the box body 1 through the fixed bracket 2, and its upper opening communicates with the return pipe 16 connected to the top of the solar water heater water tank through the variable diameter interface 12. The bottom of the movable container is connected with the transmission rod 8. A ball valve 14 connected to the water inlet pipe 17 of the water tank is fixed in the casing 1 by a fixed bracket 18 . 11-1, 11-2 are water inlet...

Abstract

The invention provides an automatic control device for water inlet of a water tank, which is simple in structure and low in cost. According to the automatic control device, a valve on a water inlet pipeline can be automatically closed after the water tank is filled with water, so that water sources are saved. The automatic control device comprises the ball valve, a bracket, a movable container and a water return pipe, wherein the ball valve is arranged on the water inlet pipeline of the water tank, the movable container is in sliding connection with the bracket up and down and an opening is formed in the upper part of the movable container; the upper part of the water tank and the movable container communicate through the water return pipe, and a switching on-off valve rod of the ball valve is in rotating connection with the movable container.

Description

[0001] Technology area [0002] The invention relates to a water tank automatic control device, in particular to a water tank automatic control device on a solar water heater. Background technique [0003] Solar water heaters are very practical energy-saving products. A gate valve is generally arranged on the water inlet pipe of its water tank, and when water enters, the gate valve is opened, and after the water in the water tank is full, the gate valve is closed. Since the switch of the gate valve needs to be manually controlled, someone needs to wait and observe whether the water tank is full when water is entering, which wastes valuable human resources; in addition, even if someone closes the valve, it is inevitable that the water source will not be wasted. Also some solar water heaters have used the water inlet automatic control device to automatically stop the water inlet after the water tank is full, but its structure is complicated and the cost is very high. Just beca...
