[0031] The features and exemplary embodiments of various aspects of the present application will be described in detail below with reference to the drawings. To make the purpose, technical solutions and advantages of the present application more clear, the present application will be further described in detail below with reference to the drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, but not to limit the present application. The present application can be implemented without some of these specific details for those skilled in the art. The following description of the embodiments is only to provide a better understanding of the present application by showing examples of the present application.

[0032] It should be noted that, in this paper, relationship terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between the entities or operations. Moreover, the terms "include", "contain" or any other variants thereof are intended to cover non-exclusive inclusion, so that the process, method, article or equipment including a series of elements not only includes those elements, but also includes other elements not explicitly listed or inherent to such process, method, article or equipment. Without more limitations, the elements defined by the statement "include" do not exclude the presence of other identical elements in the process, method, article or equipment including the elements.

[0033] The pipeline gas self-closing valve, referred to as self-closing valve, is installed on the low-pressure gas system pipeline. When the pipeline gas pressure appears underpressure or overpressure, it can automatically close the device which must be manually opened without electricity or other external power. The self-closing valve installed at the end of the pipeline after the gas meter and connected with the stove connecting hose should have the function of closing under pressure.

[0034] The self-closing valve has at least the following functions:

[0035] 1. Over-flow automatic closing: automatically closed when the bellows (hose) is aging and falling off

[0036] 2. Gas stop automatic closing: automatically closed when gas is stopped or not supplied, and always kept closed to prevent gas leakage when gas is supplied again

[0037] 3. Under-pressure automatic closing: automatically closed when gas is used at peak, frozen or blocked by debris in the pipeline, to prevent backfire or fire

[0038] 4. Over-pressure automatic closing: automatically closed when the pressure exceeds the safety line to prevent the hose from falling off

[0039] The gas self-closing valve is usually installed on the indoor gas pipeline, and the gas self-closing valve has the functions of gas overpressure automatic closing, gas underpressure automatic closing, gas over-flow automatic closing, etc.

[0040] When gas leaks, the over-flow assembly installed in the self-closing valve controls the automatic closing of the self-closing valve, thereby ensuring gas safety. The existing gas self-closing valve is usually installed naked on the outside of the wall. On the one hand, the self-closing valve protruding outside the wall is easy to be damaged, on the other hand, it also affects the overall appearance of the wall.
