WA42F46-16C襯氟(fu)安(an)全(quan)(quan)閥(fa)(fa)是根據壓(ya)力(li)系(xi)(xi)統(tong)(tong)(tong)的工作壓(ya)力(li)自(zi)動啟(qi)(qi)閉(bi)，一般安(an)裝(zhuang)于封閉(bi)系(xi)(xi)統(tong)(tong)(tong)的設備(bei)或(huo)管路(lu)上保護系(xi)(xi)統(tong)(tong)(tong)安(an)全(quan)(quan)。當設備(bei)或(huo)管道(dao)內(nei)壓(ya)力(li)超過彈簧式安(an)全(quan)(quan)閥(fa)(fa)設定(ding)壓(ya)力(li)時，即自(zi)動開(kai)啟(qi)(qi)泄壓(ya)，保證設備(bei)和管道(dao)內(nei)介質(zhi)壓(ya)力(li)在設定(ding)壓(ya)力(li)之下，保護設備(bei)和管道(dao)正常工作，防(fang)止發生意(yi)外，減少損失。彈簧式安(an)全(quan)(quan)閥(fa)(fa)在系(xi)(xi)統(tong)(tong)(tong)中起(qi)安(an)全(quan)(quan)保護作用。當系(xi)(xi)統(tong)(tong)(tong)壓(ya)力(li)超過規定(ding)值時，彈簧式安(an)全(quan)(quan)閥(fa)(fa)汀開(kai)，將系(xi)(xi)統(tong)(tong)(tong)中的一部分(fen)氣體排(pai)入(ru)大氣，使系(xi)(xi)統(tong)(tong)(tong)壓(ya)力(li)不超過允許(xu)值，從而保
