摘要
介绍了一种不需要任何电源的全机械式地震煤气阀门的结构原理及性能,当地震发生时,可按设定的地震加速度(或烈度)值自动关闭阀门,切断煤气(或其它流体)的流动。当需要接通煤气时,仅需拨动地震阀门的复位开关,即可供应煤气。它为能源供应系统的地震动安全控制提供了一种新设备,可防止地震次生灾害的发生。
Structural principle and performance of a new mechanical seismic gas valve,which does not need any kind of power,are introduced.The valve would be shutoff automatically according to the set seismic acceleration(or intensity) and the gas(or other liquation) would be shutoff in case of earthquakes.Gas supply is restored by resetting the valve switch only.The valve is provided as a new equipment to control the earthquake safety of energy resources system and prevent secondary disasters.
