Spring-loaded safety valve spring is delivered to the valve on the container or force to balance the pipeline pressure by adjusting the elastic springs to balance the medium on the pressure valve control media pressure to achieve the objective of safety valve lever weights Is to use a heavy hammer through the transmission lever to force the valve to balance the pipe or container medium pressure by adjusting the weights of the valve to balance the role of media from the valve on the pressure, media pressure to achieve the purpose of control ; Pilot of the main safety valve by valve components and sub-valve, to promote the role of Vice valve main valve action, also known as the pulse safety valve.

弹簧式安全阀是利用弹簧传递到阀瓣上的作用力来平衡容器或管道内压，通过调节弹簧的松紧来平衡介质对阀瓣的压力从而达到控制介质压力的目的；杠杆重锤式安全阀是利用重锤通过杠杆传递到阀瓣上的作用力来平衡管道或容器内介质的压力，通过调整重锤对阀瓣的作用距离来平衡介质对阀瓣的压力，从而达到控制介质压力的目的；先导式安全阀是由主阀和副阀组成，借副阀的作用带动主阀动作，又称为脉冲式安全阀。

Selection of safety valve Decided by the operating pressure safety valve nominal pressure, the decision by the operating temperature range of temperature safety valve from the computed value of the decision constant pressure safety valve spring or a lever set pressure range, then the safety valve according to the decision to use media materials and structure type, and then calculated according to the safety valve Discharge valve throat diameter.

安全阀的选用由操作压力决定安全阀的公称压力，由操作温度决定安全阀的使用温度范围，由计算出的安全阀的定压值决定弹簧或杠杆的定压范围，再根据使用介质决定安全阀的材质和结构型式，再根据安全阀泄放量计算出安全阀的喉径。
