Problems solved by technology

[0002] In the prior art, if the sealing of the valve is not reliable enough, the valve will easily leak after being used for a long time. After the valve leaks, it needs to be replaced with a new valve, which increases the cost of use
[0003] Mixed water is often used in life, that is, hot water and cold water are mixed and flow out from the water outlet. In this case, if the valve is not operated properly, it is easy to be scalded

Abstract

The invention provides a double-seal valve which comprises a valve body and an elastic wedge-shaped valve element. A water inlet and a water outlet are formed in the valve body; the wedge-shaped valve element is arranged at the lower end of an operation rod; a wedge-shaped movement space matched with the wedge-shaped valve element is arranged in the valve body; the operation rod drives the valve element to move up and down in the wedge-shaped movement space; and a sealing ring is arranged at the position, matched with the operation rod, of the valve body. The double-seal valve adopts the elastic wedge-shaped structure, so that sealing is more reliable.

Description

technical field [0001] The invention belongs to the field of valves, and in particular relates to a double-seal valve. Background technique [0002] In the prior art, if the sealing of the valve is not reliable enough, the valve will easily leak after being used for a long time. After the valve leaks, it needs to be replaced with a new valve, which increases the cost of use. [0003] Mixed water is often used in life, that is, hot water and cold water are mixed and flow out from the water outlet. In this case, if the valve is not operated properly, it is easy to be scalded. Contents of the invention [0004] In view of this, the present invention aims to propose a double-seal valve to solve the above problems. [0005] In order to achieve the above object, the technical solution created by the present invention is achieved in this way: [0006] A double-seal valve, including a valve body and an elastic wedge-shaped valve core. The valve body is provided with a water inle...
