Gas pipe valve regularly closing device

Abstract

The invention relates to a gas pipe valve regularly closing device, which comprises helical springs a gear drive component, a timing component and a valve switch component, which are arranged in cavities of upper and lower shells with knobs, and also comprises an emergency button component arranged in the upper shell, wherein the emergency button component is matched with the timing component by an emergency button connected with a spring. The device is directly arranged on indoor valve of a user without any change of the traditional valve and pipeline, so the device has high practicability; due to the timing shutting-off function, the potential safety hazard is basically eliminated for the user who often forgets to close the valve; the user can adjust the using time at any time and manually closes the valve in time by using the emergency closing mechanism according to the using conditions of the user, so the gas consumption is reduced, various accidents caused by forgetting to close the valve are avoided; the use is more flexible and convenient and the leakage accident can be prevented at any time. Thus, the device has a dual-protection function and is safe and reliable in use.

Description

technical field [0001] The invention relates to a safety device used on a gas pipeline valve, in particular to a timing closing device for a gas pipeline valve installed on a liquefied gas or natural gas pipeline valve in a user's room. Background technique [0002] With the development of the modernization process, liquefied petroleum gas or natural gas gas pipelines have entered the households of ordinary people, providing people with convenient and clean energy. However, convenience is accompanied by hidden dangers. The accident rate due to improper operation is very high. The main reason is that many users often forget to close the switch of the indoor pipeline valve. Due to human negligence, a great safety hazard is left, which not only wastes a lot of gas, but also causes damage to Cause fire and explosion and poisoning incident, another reason is exactly because the rubber hose that is transported to cooking stove from pipeline fails to change frequently and ages, and...
