Peb-thooj threaded kawg kev twb kev txuas pob li qub muaj xws li ib tug 3- thooj lub cev thiab 2-piece threaded kawg kev twb kev txuas. Peb qhov chaw yog sib sau ua ke los ntawm kev hla cov bolts los ntawm cov ntsia liaj qhov rooj hauv cov xov sab nrauv thiab nruj nrog cov txiv ntseej. Lub 2 threaded kawg kev sib txuas yuav tsum tau txuas nrog threaded yeeb nkab kawg ua ntej lub cev tau sib sau ua ke ntawm lawv. Rau kev pabcuam, lub cev tuaj yeem raug tshem tawm los ntawm tsuas yog tshem cov txiv ntoo thiab bolts yam tsis tau tshem tawm qhov kawg kev sib txuas. Nws yog ua los ntawm stainless hlau SS316 khoom nrog PTFE sealing khoom.
Peb lub qhov (socket) welded pob valve: Nws yog lub valve siv los pib lossis nres cov dej ntws hauv cov kav dej. Nws nta ib tug tag nrho bore tsim thiab lub quarter-tig kov.

Cov cuab yeej ntsuas phoo ntawm tus kov yog siv los ua lub tshuab xauv kom paub meej tias lub valve tsuas yog nyob rau hauv txoj haujlwm qhib lossis tsuas yog nyob rau hauv txoj haujlwm kaw.
Peb lub qhov (socket) weld pob valve muaj ob daim ntawm lub qhov (socket) weld kawg txuas thiab lub cev valve. Lub cev valve txuas nrog ob lub qhov (socket) vuam xaus thiab sib sau ua ke los ntawm bolts thiab ceev. Lub 2 thooj qhov (socket) weld kawg txuas yuav txuas rau lub cev ua ntej nws tau sib sau ua ke rau lub tiaj kawg hom yeeb nkab kawg. Lub cev tuaj yeem raug tshem tawm los ntxuav yam tsis tau tshem tawm 2 welded kawg kev sib txuas. Lub pob valve no yog ua los ntawm stainless hlau SS316 khoom thiab PTFE sealing khoom.
