密封圈式安全阀

Gasket like relief valve

针对弹簧式安全阀高压工作时开闭可靠性差，而销钉、膜片式安全阀不耐疲劳状况，设计出密封 圈式一次动作安全阀。未超载时，密封圈密封保压，超载时，密封圈爆破，失去密封作用而泄压。

In order to solving the problems of the poor stability of spring relief valve working under high pressure and the poor fatigue resistance of pin and membrane relief valve, an one-off gasket like relief valve is designed. The gasket keep the pressure when the load is under the safe value, otherwise, the gasket breaks and relieves the load.
