Problems solved by technology

[0002] The gas valve is used to control the connection and cut-off of the gas in the gas pipeline. There are safety hazards in the use of the gas pipeline, such as: 1. The pressure reducer is out of control or the gas pipeline is damaged or falls off, which will cause excessive gas flow; 2. The user uses Improper use will cause the indoor temperature to be too high and cause a sudden fire.
The existing gas valve only has the function of manual switch, the safety performance is poor, and the safety of users cannot be guaranteed

Abstract

The invention discloses a home gas valve. The home gas valve comprises a valve body which is provided with a gas channel. The home gas valve is characterized in that the gas channel is divided into a gas inlet section, a switching section and a gas outlet section. The inner diameter of the switching section of the gas channel is larger than that of the inlet end of the gas outlet section. A sliding block for sealing is arranged in the gas channel, and the bottom face area of the sliding block is smaller than the cross section area of the switching section of the gas channel and larger than the area of the inlet end of the gas outlet section of the gas channel. A sealing pad for switching off the gas channel is arranged on the end face of the sliding block. The valve further comprises a thermosensitive inductor pushing the sliding block to move axially. The thermosensitive inductor pushes the sliding block to move axially to switch off the gas channel when started. Compared with the prior art, the home gas valve has the advantages that the safety performance is greatly improved, and personal safety and property safety of users are guaranteed.

Description

technical field [0001] The invention relates to an improved invention of a gas valve, in particular to a household gas valve. Background technique [0002] The gas valve is used to control the connection and cut-off of the gas in the gas pipeline. There are safety hazards in the use of the gas pipeline, such as: 1. The pressure reducer is out of control or the gas pipeline is damaged or falls off, which will cause excessive gas flow; 2. The user uses Improper use will cause the indoor temperature to be too high and cause a sudden fire. The existing gas valve only has the function of manual switching, and its safety performance is poor, so the safety of users cannot be guaranteed. Contents of the invention [0003] In view of the technical problems existing in the background technology, the technical problem to be solved by the present invention is to provide a household gas valve with high safety performance. [0004] In order to solve the above technical problems, the p...
