Brass valve

Abstract

The brass valve comprises a valve body, a valve element is arranged in the valve body, an operation part is arranged on the valve body, a water inlet, a water outlet and a water drainage opening are formed in the valve body, and a water drainage pipeline is arranged in the valve body; one end of the drainage pipeline extends out of the valve body to form a water outlet; a first communicating pipe and a second communicating pipe are fixed in the valve body, located on the two sides of the valve body and matched with the valve body respectively. The first communicating pipe extends out of the valve body to form a water inlet, and the second communicating pipe is communicated with a drainage pipeline; a rubber sliding block is arranged in the drainage pipeline, and a spring is fixed to the position, back to the water outlet, of the rubber sliding block. A bypass pipe is arranged on the communicating pipe, the diameter of the bypass pipe is smaller than that of the second communicating pipe, the bypass pipe is communicated with the drainage pipe, the drainage port is located below the drainage pipe, and a water outlet hole is formed in the bottom end of the drainage pipe. According to the brass valve, liquid can be prevented from being retained in the valve body, so that the valve body is frozen to crack in a cold environment.

Description

technical field [0001] The invention relates to the field of brass products, in particular to a brass valve. Background technique [0002] Brass valves are common valves. Existing brass valves mainly include two types. One is manual control. This type of brass valve is simple in structure and low in cost. If the liquid cannot be drained in time, it will often be frozen and cracked. It is also automatically controlled. The structure of the automatic control is complicated and the cost is high. Moreover, the electronic components are greatly affected by the temperature, and they are often out of control in the cold environment, which makes the valve Was cracked. Contents of the invention [0003] The object of the present invention is to provide a kind of energy-saving brass valve to solve the above problems. [0004] The technical solution of the present invention is: a brass valve, including a valve body, a valve core is arranged in the valve body, an operating part for ...
