Problems solved by technology

The pressure of the main pipeline of the natural gas company is relatively high. When the abnormality of the pressure regulating device is not found in time, the high pressure will be directly supplied to the household users and cause danger. The connection between the household gas pipeline and the stove requires a connecting hose. Accidents caused by gas leakage due to pest damage and other reasons

Abstract

The invention discloses a self-closing valve of a gas pipeline. The self-closing valve comprises a valve body. A channel where gas passes through is arranged in the valve body in a through manner, a metal pull rod capable of moving up and down is arranged in the channel, a first magnet capable of moving up and down is arranged in the channel, the first magnet is located below the pull rod and is fixedly connected to a clamping seat through a screw, a notch is formed in the clamping seat, a second magnet is fixedly connected in the notch, the pull rod is connected to the first magnet, the second magnet and the clamping seat by means of a magnetic force, a sealing part capable of closing the channel is arranged in the channel, and one end of the sealing part is fixedly connected to a third magnet. By arranging a series of structures, in the using process of the self-closing valve, the valve body is closed when a gas pressure is greater than a set maximum value and smaller than a set minimum value and a flow is greater than a set maximum value. When the pipeline pressure is greater than a set opening pressure, a gas inlet is not opened, so that the safety performance of the self-closing valve during use is guaranteed.

Description

technical field [0001] The invention relates to the field of natural gas household pipeline valve equipment, in particular to a gas pipeline self-closing valve. Background technique [0002] With the popularization of natural gas in the country and entering thousands of households, more and more users use natural gas, and accidents caused by gas leakage occur frequently. The pressure of the main pipeline of the natural gas company is relatively high. When the abnormality of the pressure regulating device is not found in time, the high pressure will be directly supplied to the household users and cause danger. The connection between the household gas pipeline and the stove requires a connecting hose. Insect pest damage and other reasons cause gas leakage and cause accidents. There are various kinds of gas self-closing valves, which can solve some safety problems of gas leakage. Some products need to be powered by electric energy. When there is no power supply, they will lo...
