安全阀是保障锅炉安全运行的最重要的安全附件,必须灵敏,可靠。没有安全阀或者安全阀失灵的锅炉是禁止运行的。工业锅炉安全阀,常见的有重锤杠杆式和弹簧式两类。一、重锤杠杆式安全阀重锤杠杆式安全阀的作用原理是利用重锤的重量,通过杠杆作用,将阀芯紧紧地压在阀座上,使锅炉内的压力保持在允许压力之内,当锅炉压力超过允许值时,阀芯被顶 Safety valve is to protect the safe operation of the most important safety accessories, must be sensitive and reliable. No safety valve or safety valve failure of the boiler is prohibited. Industrial boiler safety valve, a common weight lever type and spring type. First, the hammer leveraged safety valve Hammer lever safety valve principle is the use of heavy hammer weight, through the leverage, the valve core tightly pressed on the valve seat, the pressure inside the boiler to maintain the pressure Within the boiler when the pressure exceeds the allowable value, the spool is top
