近日,四川石油管理局勘察设计研究院申报的弹簧隔离安全阀获得国家专利,该安全阀采用了注入密封油脂和两道摩擦系数低、滑动面积小的密封件,解决了腐蚀介质外泄污染环境、内串腐蚀弹簧的技术难题。安全阀在工作时,阀腔内的腐蚀介质在润滑密封装置的封闭下,不能穿过阀杆的滑动面而泄漏到弹簧导筒内对弹簧造成腐蚀,也不能进入大气对环境造成
Recently, Sichuan Petroleum Administration Bureau of Investigation and Design Institute declared the spring isolation valve won the national patent, the safety valve used to inject sealed grease and two low coefficient of friction, sliding area of the seal to solve the leakage of corrosive media contaminated environment , Within the string of corrosion spring technical problems. When the safety valve is in operation, the corrosive medium in the valve cavity can not leak through the sliding surface of the valve stem to the spring guide tube to cause corrosion of the spring or enter the atmosphere due to the sealing of the lubricating and sealing device.
