一、進口美標安全閥產(chǎn)品概述
品牌:美國威盾VTON
進口美標安全閥,American Standard safety valve,是指按照美標ANSI及API規(guī)范設(shè)計制造,壓力為150LB,300LB,600LB,900LB,1500LB,用于管道,儲罐,或者設(shè)備的超壓保護裝置的安全閥。
美國威盾VTON美標安全閥按API RP520設(shè)計,適用大部分常規(guī)介質(zhì)的工礦條件,采用傘形反沖盤設(shè)計,能夠有效地提高排放壓力,閥瓣能在較小的超壓下迅速達到全啟的高度,從而達到額定排量;閥座和閥瓣的密封面堆焊硬質(zhì)合金,再經(jīng)精心研磨后保證安全閥的密封性和使用壽命。
二、進口美標安全閥產(chǎn)品特征
1、美標安全閥閥座與閥體為可分離式,維修方便、經(jīng)濟
2、美標安全閥傘形反沖盤和調(diào)節(jié)圈能夠有效地提高升力,閥瓣在較小超壓下就能夠迅速全開啟,排放介質(zhì),從而達到保護設(shè)備的目的
3、美標安全閥調(diào)節(jié)圈能夠調(diào)整滿意的啟閉壓差
4、美標安全閥對反沖盤和導(dǎo)套、閥桿和調(diào)整螺釘?shù)牟牧线M行合適的選擇以及間隙的適當選取,保證閥瓣的運動靈活
5、美標安全閥密封面處堆焊硬質(zhì)合金,表面精研后保證了安全閥的耐蝕性、高密封性和使用壽命長
6、美標安全閥彈簧和波紋管選材及加工工藝講究,并進行嚴格的測試和檢查
三、進口美標安全閥執(zhí)行標準
設(shè)計規(guī)范:API RP 520
結(jié)構(gòu)長度:API RP 520
法蘭連接:ANSI B16.34
試驗與檢驗:API 527
