Khoom Description
Laum yeeb nkab float valve sealing rings yog cov khoom siv tseem ceeb siv hauv kev ua haujlwm drilling, feem ntau los tiv thaiv cov dej ntws los ntawm cov yeeb nkab laum thaum lub sijhawm drilling. Lawv feem ntau yog ntsia rau hauv lub ntab valve, uas yog siv los tswj cov dej ntws ntawm cov dej drilling, kom ntseeg tau tias cov kua dej tsis ntws mus rau qhov sib txawv thaum drilling.
Nta ntawm Drill Pipe Float Valve Sealing Rings
- Floating foob tsim: Laum cov yeeb nkab ntab valve sealing rings txais yuav cov qauv tsim elastic, uas tuaj yeem hloov kho qhov chaw sib cuag thaum nruab nrab siab hloov, thiaj li ua kom ntseeg tau qhov kev sib khi ua tau zoo.
- Bidirectional sealing tsim: Lub nplhaib sealing ntawm lub ntab valve txais cov kua dej dynamic yam ntxwv kom ua tau raws li kev them nyiaj bidirectional ntawm lub sealing nto los xyuas kom meej tias lub valve foob raws li lub teb chaws tus qauv.
- Tsis tshua muaj kev khiav hauj lwm torque: lub ntab valve txais 360 degree linear sealing kev sib cuag ntawm lub floating sealing nplhaib thiab lub valve phaj, ua ke nrog ib tug eccentric tsim kom nws muaj ib tug qis kev khiav hauj lwm torque thaum lub sij hawm ua hauj lwm.
- Non-contact sealing: Laum yeeb nkab float valve sealing rings yog ib qho tsis sib cuag nrog lub nplhaib uas tsis muaj kev sib txhuam sealing nto, yog li nws tuaj yeem txo cov dej xau zoo thiab ua rau muaj kev kub ntxhov thiab kev ntseeg siab nyob rau hauv ib puag ncig siab.
- Cov khoom siv ruaj khov: Lub nplhaib sealing ntawm lub ntab valve feem ntau yog ua los ntawm cov ntaub ntawv elastic, xws li roj hmab nitrile (NBR, Buna-N) thiab fluoro roj hmab (Viton®, FKM), uas tuaj yeem tswj xyuas kev sib khi zoo hauv qhov chaw ua haujlwm hnyav.
Hom Sealing Rings
Cov Khoom Siv Khoom Siv: Cov ntsaws ruaj ruaj feem ntau yog tsim los ntawm cov ntaub ntawv ua tau zoo xws li Viton® lossis lwm yam fluoropolymers uas muab kev tiv thaiv zoo heev rau hnav corrosion, thiab kub siab (txog 400 degree F lossis 204 degree).
Tsim Variations: Cov qauv sib txawv ntawm ntab li qub (xws li plunger thiab flapper) siv cov ntsaws ruaj ruaj hauv ntau qhov kev teeb tsa los ua kom zoo sealing kev ua tau zoo nyob rau hauv kev ua haujlwm sib txawv. Piv txwv li, qhov chaw nres nkoj li qub siv cov ntsaws ruaj ruaj tsim los tswj kom muaj zog hydrostatic ntau dua thaum lub sij hawm tawg.
