Gas valve capable of detecting gas leakage

Abstract

The invention discloses a gas valve capable of detecting gas leakage. The gas valve capable of detecting gas leakage comprises a gas valve body, wherein a screwing ring is arranged on the gas valve body; a threaded pipe is fixedly connected to one side wall of the screwing ring; a sealing casing pipe is fixedly connected to one side wall, close to the threaded pipe, of the screwing ring; a base isfixedly connected to the outer side wall of the sealing casing pipe; and an LED (Light Emitting Diode) lamp is arranged on the base. When gas leaks at a connection part between the gas valve body anda gas stop valve, the gas valve capable of detecting gas leakage can stop the gas from escaping into the air, and stores the leaked gas so as to prevent safety accidents caused by the gas leakage. Compared with a traditional method of using a sensor to detect the gas leakage, the gas valve capable of detecting gas leakage has the advantages that the cost is greatly reduced, and therefore, the gasvalve capable of detecting gas leakage is convenient for popularization in ordinary households; flickering lights are used for warning a user and reminding the user that the gas leaks; and compared with a traditional constant lighting indicator light, the flickering lights have a relatively good warning effect and are easily observed and noticed.

Description

technical field [0001] The invention relates to the technical field of gas valves, in particular to a gas valve capable of detecting gas leakage. Background technique [0002] The gas valve, also called the pressure reducing valve, is a valve used to connect the gas pipeline of the gas stove and the gas cylinder. A gas stop valve will be provided on the top of the gas cylinder, and the gas valve is generally installed at the installation pipe of the gas stop valve when installed. [0003] When most households replace the gas cylinder, they generally install the gas valve and the gas stop valve independently, so it is easy to cause gas leakage at the connection between the gas valve and the gas stop valve due to improper operation, and the gas leakage is very easy. It is easy to cause safety accidents. When the existing technology detects the situation of gas leakage, it is generally realized by means of gas detection sensors. However, due to the high cost of use, it cannot ...

Problems solved by technology

[0004] The purpose of the present invention is to solve the shortcomings in the prior art, such as: when most families replace the gas cylinder, they generally install between the gas valve and the gas stop valve independently, so it is easy to cause gas leakage due to improper operation. There is a gas leak at the connection between the valve and the stop valve, and the gas leak is likely to cause a safety accident. When the gas leak is detected in the prior art, it is generally realized by means of a gas detection sensor, but due to the high cost of use High, it cannot be popularized in ordinary households on a large scale, and even if it can be detected quickly at the first time of gas leakage, the gas has already escaped into the air at this time
