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 a self-closing valve with an earthquake induction function, and a gas system, and belongs to the field of valves. The self-closing valve mainly comprises a fixing frame, a valvebody, a valve element, a pulling mechanism, a locking mechanism, an unlocking mechanism and an earthquake induction mechanism. The fixing frame is used for fixing other parts to a foundation, the valve element is located in the valve body, and the pulling mechanism is used for pulling the valve element to close the valve; and the locking mechanism is used for locking the pulling mechanism, so that the pulling mechanism is incapable of pulling the valve element in the case of no earthquake. In the case of an earthquake, the earthquake induction mechanism unlocks the locking mechanism through the unlocking mechanism, and at this moment, the pulling mechanism pulls the valve element to close the self-closing valve. The self-closing valve is adopted in the gas system, so that in the case of an earthquake, a conveying pipeline of the gas system is automatically cut off; and the accidents of explosion and the like due to gas leakage are 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-...
