NSW API 602 ntiaj teb valve, qhib thiab kaw ib feem ntawm forged steel rooj vag valve ntawm lub bolt bonnet yog lub rooj vag.Txoj kev txav ntawm lub rooj vag yog perpendicular mus rau cov kev taw qhia ntawm cov kua.Lub forged steel rooj vag valve tsuas yog qhib thiab kaw, thiab tsis tuaj yeem hloov kho thiab throttled.Lub rooj vag ntawm forged steel rooj vag valve muaj ob qhov chaw sib khi.Ob qhov chaw sib khi ntawm qhov feem ntau hom rooj vag valve tsim ib lub voj voog, thiab lub kaum sab xis sib txawv nrog lub valve tsis.Cov hom tsav ntawm forged steel rooj vag li qub yog: phau ntawv, pneumatic, hluav taws xob, roj-kua sib txuas.
Lub sealing nto ntawm lub forged steel rooj vag valve tuaj yeem raug kaw tsuas yog los ntawm qhov nruab nrab siab, uas yog, lub siab nruab nrab yog siv los nias lub sealing nto ntawm lub rooj vag mus rau lub rooj zaum valve ntawm sab nraud los xyuas kom meej qhov sealing nto, uas yog. tus kheej sealing.Feem ntau lub rooj vag valve raug yuam kom kaw, uas yog, thaum lub valve raug kaw, nws yog ib qho tsim nyog yuav tsum tau yuam lub rooj vag phaj tiv thaiv lub rooj zaum ntawm lub rooj zaum los ntawm kev quab yuam sab nraud los xyuas kom meej lub sealing nto.
Lub rooj vag ntawm lub rooj vag valve txav linearly nrog lub valve qia, uas yog hu ua tus nqa qws rooj vag valve (tseem hu ua qhib qws rooj vag valve).Feem ntau muaj ib txoj hlua trapezoidal ntawm lub lifting pas nrig.Cov txiv ntseej txav los ntawm sab saum toj ntawm lub valve thiab cov lus qhia zawj ntawm lub valve lub cev kom hloov cov lus tsa suab mus rau hauv cov lus tsa suab, uas yog, kev khiav hauj lwm torque rau hauv kev khiav hauj lwm thrust.
Qhov zoo ntawm forged steel rooj vag valve
1. Tsis tshua muaj dej tsis kam.
2. Lub zog sab nraud yuav tsum tau qhib thiab kaw yog me me.
3. Kev khiav dej num ntawm qhov nruab nrab tsis txwv.
4. Thaum qhib tag nrho, qhov yaig ntawm lub sealing nto los ntawm kev ua haujlwm nruab nrab yog me dua li ntawm lub ntiaj teb valve.
5. Cov duab yog qhov yooj yim thiab cov txheej txheem casting yog qhov zoo.
