Embodiment

[0051] Please refer to figure 1 , the present embodiment provides an earthquake-sensing automatic closing valve 100 (hereinafter referred to as a valve), which is in a normally open state and mainly includes a fixed frame 180, a ball valve 110, a pulling mechanism 140, a locking mechanism 150, an unlocking mechanism 160 and an earthquake-sensing Agency170. Fixture 180 is used to fix other components on the foundation, and pulling mechanism 140 is used for the valve rod 112 on the ball valve 110, to close the automatic closing valve; The mechanism 140 cannot pull the valve stem 112; when an earthquake occurs, the earthquake sensing mechanism 170 unlocks the locking mechanism 150 through the unlocking mechanism 160, and at this time, the pulling mechanism 140 pulls the valve stem 112 to close the valve.

[0052] Specifically, the above-mentioned ball valve 110 adopts an ordinary ball valve, and the switching of the valve opening and closing is realized after the valve stem is rot...

Abstract

The invention provides an earthquake safety valve, which belongs to the field of valves and mainly includes a fixed frame, a ball valve, a pulling mechanism, a locking mechanism, an unlocking mechanism and an earthquake sensing mechanism. The fixing frame is used to fix other parts on the foundation, the valve stem is arranged on the ball valve, and the pulling mechanism is used to pull the valve stem to close the ball valve; the locking mechanism is used to lock the pulling mechanism so that the pulling mechanism cannot pull when the earthquake does not occur. spool. When an earthquake occurs, the earthquake sensing mechanism will unlock the locking mechanism through the unlocking mechanism. At this time, the pulling mechanism will automatically close the valve by pulling the stem. When an earthquake occurs, the gas system using the above-mentioned earthquake safety valve assembly can automatically cut off the transmission pipeline of the gas system; prevent accidents such as explosions caused by gas leakage.

Description

technical field [0001] The invention relates to the field of valves, in particular to an earthquake safety valve assembly and a gas system. Background technique [0002] Oil pipelines and gas pipelines generally use valves to switch the pipeline on and off. When an accident may occur, it is very important to close the main valve in time. When an earthquake occurs, people may not have time to close the valve, which poses a relatively large safety hazard. Therefore, be badly in need of developing a kind of valve that can close automatically. Contents of the invention [0003] The object of the present invention is to provide an earthquake safety valve assembly, when an earthquake occurs, the above-mentioned automatic closing valve can be automatically closed. [0004] The present invention is achieved like this: [0005] An earthquake safety valve assembly comprising: [0006] fixed frame; [0007] A ball valve, the ball valve includes a valve body, a valve core and a v...
