Problems solved by technology

[0002] The upper and lower water pipes of solar water heaters must be insulated in winter, and some are wrapped with electric heating tape or thermal insulation cotton. This method has the disadvantages of high material cost and power consumption, and the effect is not ideal, and the pipes often freeze and crack Phenomenon
In order to solve the above problems, some use the electromagnetic pipeline emptying valve, that is, to empty the water in the pipeline when it is stopped. This is to use the electromagnetic principle to make the diaphragm in the emptying valve open and close to cut off the liquid in the pipeline. For the purpose of air or gas, the coil of this emptying valve is easy to burn, and the diaphragm is easy to scale, thus losing the emptying effect

Embodiment Construction

[0010] Such as figure 1 , 2 As shown: 2 is a valve body, a channel 4 is processed in the valve body, and a first water inlet and outlet 11 communicating with the channel 4 is processed on the valve body 2 at one end of the channel 4 .

[0011] On the valve body 2 at the other end of the passage 4, a second water inlet and outlet 7 communicating with the passage 4 is processed in an upward direction.

[0012] The above-mentioned first water inlet and outlet 11 and the second water inlet and outlet 7 are threaded holes, which are convenient for connecting with pipes through pipe joints.

[0013] Between the first water inlet and outlet 11 and the second water inlet and outlet 7 , a ball hole 8 communicating with the channel 4 is processed on the lower side of the valve body 2 , that is, in the downward direction, and the sealing ball 5 is located in the ball hole 8 . There is a wire hole 9 at the outer port of the ball hole 8, and the wire hole 9 is threadedly connected with a...

Abstract

The invention relates to an emptying valve for a pipeline of a solar energy water heater. The emptying valve comprises a valve body, wherein a passage is formed in the valve body; a first water inlet and outlet communicated with the passage is formed on the valve body on the lower side of one end of the passage; a second water inlet and outlet communicated with the passage is formed on the valve body at the other end of the passage; a ball hole communicated with the passage is formed on the lower side of the valve body between the first water inlet and outlet and the second water inlet and outlet; a seal ball is positioned in the ball hole; an adjusting screw plug is arranged at a port on the outer side of the ball hole; the seal ball is matched with a port on the inner side of the first water inlet and outlet; a blocking part is connected between the second water inlet and outlet and the ball hole on the ball body; and the end part of the blocking part is positioned in the passage. The emptying valve with the structure has the advantages of simple overall structure, good emptying effect and long service life and is flexible and reliable to move, thereby effectively protecting thewater supply and drainage pipeline of the solar energy water heater.
