Embodiment

[0053] Please refer to figure 1 , the present embodiment provides an earthquake-sensing automatic closing valve 100 (hereinafter referred to as valve), which is in a normally open state and mainly includes a fixed frame 180, a valve body 110, a valve core 120, a pulling mechanism 140, a locking mechanism 150, an unlocking Mechanism 160 and Seismic Sensing Mechanism 170. Fixture 180 is used to fix other parts on the foundation, spool 120 is positioned at valve body 110, and pulling mechanism 140 is used for pulling spool 120 to close automatic closing valve; Locking mechanism 150 is used for locking pulling mechanism 140, makes earthquake When it does not happen, the pulling mechanism 140 cannot pull the spool 120; when an earthquake occurs, the earthquake sensing mechanism 170 unlocks the locking mechanism 150 through the unlocking mechanism 160. At this time, the pulling mechanism 140 pulls the spool 120 to automatically close the valve.

[0054] Specifically, please refer t...

Abstract

The invention provides an earthquake induction automatic closing valve and a gas system, which belong to the field of valves and mainly include a fixed frame, a valve body, a valve core, 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 core is located in the valve body, and the pulling mechanism is used to pull the valve core to close the above valve; the locking mechanism is used to lock the pulling mechanism so that the pulling mechanism cannot pull the valve when the earthquake does not occur. core. When an earthquake occurs, the earthquake sensing mechanism unlocks the locking mechanism through the unlocking mechanism. At this time, the pulling mechanism pulls the spool to automatically close the valve. The above-mentioned gas system adopts the above-mentioned automatic closing valve, so that when an earthquake occurs, the transmission pipeline of the gas system can be automatically cut off, and accidents such as explosion caused by gas leakage can be prevented.

Description

technical field [0001] The invention relates to the field of automatic closing valves, in particular to an earthquake-sensing automatic closing valve and a gas system. Background technique [0002] At present, solenoid valves are mostly used for the safety control of oil and gas pipelines, and the control of the solenoid valves requires alternating current or direct current. When an earthquake occurs, it is easy to cause the regional power grid to be paralyzed, making it impossible to control the oil or gas pipeline through the solenoid valve. [0003] And, when an earthquake occurs, people may not have time to shut down oil or gas pipelines. Therefore, in order to prevent an earthquake from causing secondary disasters caused by oil or gas pipeline rupture, it is urgent to develop an automatic shut-off valve that can close the oil or gas pipeline when an earthquake occurs. Contents of the invention [0004] The object of the present invention is to provide an earthquake-...
