弹簧式安全阀常见故障原因分析及解决方法

Cause Analysis and Solution of Common Faults of Spring Safety Valve

安全阀是压力容器和承压设备上最常见的超压泄放装置,当压力容器或承压设备发生超压事故时,安全阀会因超压而起跳进行泄放以防止压力容器或承压设备超压损坏,确保生产的顺利运行和设备的安全使用。根据安全阀的工作原理可以将安全阀分为重锤式安全阀、脉冲式安全阀和弹簧式安全阀,本文结合弹簧式安全阀使用实践,对弹簧式安全阀的常见故障进行了总结分析,并针对这些常见故障提出了解决方法。

Safety valve is the most common overpressure relief device on pressure vessels and pressure equipment. When overpressure accidents occur in pressure vessels or pressure equipment, safety valve will jump and release to prevent overpressure damage of pressure vessels or pressure equipment, and ensure smooth operation of production and safe use of equipment. According to the working principle of safety valve, safety valve can be divided into hammer type safety valve, pulse type safety valve and spring type safety valve. Combining with the use practice of spring type safety valve, this paper summarizes and analyses the common faults of spring type safety valve, and puts forward solutions to these common faults.
