Embodiment 1

[0044] like Figure 1-Figure 9 As shown, a gas self-closing valve includes a valve body 1 and a valve core 5, a valve hole 4a is opened in the valve body 1, a film 12, a magnetic attraction assembly 10 and a valve control valve are arranged between the valve body 1 and the valve core 5. Structure 13, through the film 12 and the valve control structure 13, the valve core 5 can be hovered at the normal valve opening position to keep the valve hole 4a open, and the valve core 5 can pass through the magnetic attraction after moving downward and upward at the normal valve opening position. The assembly 10 makes the valve core 5 close and keep the valve hole 4a closed. When the spool 5 moves downwards, the spool 5 closes the valve hole 4a through the magnetic assembly 10 and keeps it closed, the spool 5 is in the underpressure closed valve position; when the spool 5 moves upwards, the magnetic assembly 10 makes the valve When the spool 5 closes the valve hole 4a and keeps it closed...

Embodiment 2

[0059] like Figure 10 As shown, the connection structure between the cover body 3 and the body 2 is different from that of the first embodiment, and the other structures are the same as those of the first embodiment. The outer edge of the lower end surface of the cover body 3 has a protruding ring-shaped connecting ring 2a, the upper end of the body 2 is inserted into the connecting ring 2a to form a threaded connection, and the outer edge of the film 12 is pressed and fixed on the lower end surface of the cover body 3 and the upper end surface of the body 2.

Abstract

The invention provides a gas self-closing valve, and belongs to the technical field of valves. The gas self-closing valve solves the problems that an existing gas self-closing valve is prone to misoperation, and normal use of gas is affected. The gas self-closing valve comprises a valve body and a valve element, a valve hole is formed in the valve body, a leather film, a magnetic attraction assembly and a valve control structure are arranged between the valve body and the valve element, and the valve element can be suspended at the normal valve opening position through the leather film and the valve control structure to keep the valve hole open; and the valve element can close the valve hole and keep the valve hole closed through the magnetic attraction assembly after moving downwards and upwards at the normal valve opening position, the valve element comprises a valve rod, the upper end of the valve rod penetrates through the valve body and then is fixedly provided with a button, the button is sleeved with a button sleeve, and the lower end face of the button sleeve is attached to the upper end face of the valve body. When the valve element is suspended at the normal valve opening position, the upper end face of the button is flush with the upper end of the button sleeve. The gas self-closing valve can reduce the situation that gas cannot be normally used due to misoperation.

Description

technical field [0001] The invention belongs to the technical field of valves and relates to a gas self-closing valve. Background technique [0002] Gas is a widely used gas fuel. Due to the characteristics of flammable, explosive and poisonous gas, the leakage of gas is likely to cause major safety accidents. Therefore, it is necessary to ensure that the gas entering the burning appliance is maintained at a normal pressure, so that the gas is stable and fully combustion. Generally, a gas self-closing valve is installed in front of the stove, which automatically closes the valve when overpressure or underpressure occurs to prevent gas leakage. [0003] A pipeline gas safety self-closing valve disclosed in Chinese patent literature [application number: CN200920032912.1, announcement number: CN201513567U], including an upper cover, a lower cover and a valve body, the two ends of the valve body are provided with an inlet port and an outlet port , there is a valve hole in the ...
