Kev piav qhia
Cov khoom siv tau muaj zog heev uas muaj kev nyab xeeb thiab txhim khu kev qha, nws yooj yim rau kev qhib, ob xaus ntawm lub valve thiab kav hlau txuas nrog los ntawm spherical txav. Qhov sib txuas tau sib txuas ntawm cov roj hmab foob nplhaib zoo li "o" tsis yog ntawm kev ncaj ncees ntawm ob kawg ntawm cov kav dej, nws qhov kev sib foob, nws tau foob zoo heev tom qab ntsia.
Cov av nkos rooj vag valve, nrog cov qauv tsim ua kom zoo dua cov qauv ua haujlwm yog engepleed kom tau raws li cov khoom siv hluav taws xob hnyav hauv hnub no.
Lub valve conforms rau cov qauv flange Qhov ntev thiab siab ntsuam xyuas ntawm 3000 thiab 5000 psi ua haujlwm siab, 3 ", 4" thiab kub thiab txias txog 400 ° F.
Flanged kawg sib txuas-hom kev sib txuas kawg tsis tas yuav tig los yog vuam lub valve. Kev sib xyaw RTJ Flanges tau txuas rau txuam nrog cov yeeb nkab flanges nrog bolts thiab txiv ntoo.
Threaded kawg sib txuas - hom kev sib txuas kawg, kuj rov qab siv dua li ntsia hlau, yog qhov tsim nyog rau cov ntawv thov txog li 7500psi. Kab yeeb (LP) thiab muaj 8 tus xov muaj.
Taub qab weld kawg sib txuas - hom kev sib txuas lus kawg yog tsim kom phim cov pa yeeb kev txuas. Qhov ob leeg beveled xaus yog khawm ua ke thiab welded nyob rau hauv qhov chaw. Welded sib txuas yog qhov zoo tshaj plaws rau cov kev siv uas tshem tawm cov raj xa dej tsis tas yuav tsum tau.
Vuam cov lus ceeb toom: ua ntej vuam, lub rooj zaum thiab bonnet ntim yuav tsum tau muab tshem tawm ntawm lub cev valve.
