Parallel Slide Gate Valve
Dab tsi yog qhov parallel swb rooj vag valve?
Parallel Slide Gate Valveyog ib qho tshwj xeeb tsim ntawm lub rooj vag valve.
Nws yog ib qho kev xaiv rau cov tsoos saj zawg zog wedge hom rooj vag li qub.Lub disc yog nyob rau hauv ob halves, compressed caij nplooj ntoos hlav Inconel X750 loaded, lub rooj zaum ntawm parallel rooj rings.Lub disc "slides" nyob rau hauv kev sib cuag nrog cov rooj zaum, li no lub npe.
Cov discs nyob rau hauv mus tas li kev sib cuag nrog lub rooj rings, tau txais ib tug nruj seal vim lub kab rov tav inconel caij nplooj ntoos hlav nyob rau hauv nruab nrab ntawm thiab tsis muaj lub wedging system pab.
sealing mechanismntawm parallel swb rooj vag li qub.
- Thaum cov yeeb nkab siab los yog siab sib txawv ntawm ob sab yog me me, lub caij nplooj ntoos hlav compressed yuav thawb cov discs rau lub nplhaib sealing, nws yog qhov pib sealing ntawm qhov sib npaug ntawm lub rooj vag li qub nyob rau hauv qis qis.
- Thaum lub raj xa dej siab nce, txoj kab nce siab yuav thawb lub disc tawm tsam lub nplhaib lub rooj zaum nrog quab yuam nyob rau sab qis, uas ua rau lub foob thib ob.Qhov siab dua qhov nruab nrab siab, qhov kev sib khi zoo dua
Yog li no hom valve no yog siv dav hauv kev kub siab thiab kub kev pab cuam xws li chav thiab dej pub.
Qhov zoontawm qhov sib npaug swb rooj vag valve piv rau cov khoom siv ib txwm muaj xws li:
- Cov discs ntawm qhov sib npaug ntawm lub rooj vag valve yuav tsis thaiv nyob rau hauv txoj hauj lwm kaw, thaum nws yuav tshwm sim nrog ib tug wedge hom uas tau raug kaw nrog kab nyob rau hauv kub thiab qhib thaum kab txias.
- Qhov qhib / kaw torque ntawm parallel swb rooj vag valve yog qis dua li qhov sib thooj lub rooj vag valve wedge hom valve, ua rau me me actuator thiab tsis tshua kim actuation systems.
- Qhov "sliding" feature ua kom cov av tawm ntawm qhov chaw sib khi.
Cov yam ntxwv tseem ceeb ntawm NORTECH Parallel swb rooj vag li qub

Khoom Qhia:
Parallel Slide Gate Valve siv qhov twg?
Parallel Slide Gate Valve yog dav siv nyob rau hauv lub teb tshuaj, roj av, natural gas, oil thiab natural gas tsim cov khoom siv zoo, kev xa khoom thiab cov kav xa dej (Class150 ~ 2500 / PN1.0 ~ 42.0MPa, kev ua haujlwm kub -29 ~ 450 ℃), cov kav dej nrog cov xov xwm tshem tawm, cov kav dej hauv nroog, dej engineering.it yog tsim los muab Kev sib cais thiab kev sib kis ntawm cov dej ntws hauv cov kav dej lossis cov khoom siv thaum kaw, qee zaum tuaj yeem ntsia tau rau hauv lub twj tso kua mis rau kev tswj lossis tswj kev khiav.
