Qhov nominal loj ntau rau screwed kawg rooj vag li qub feem ntau me me. Piv txwv li, raws li cov qauv tsim nyog, qhov nominal loj rau tooj liab alloy thiab stainless hlau li qub feem ntau tsis tshaj DN100.
Kev sib txuas, kev ua haujlwm, thiab kev ua haujlwm siab
Txoj kev sib txuas nrog cov xov sab hauv lossis sab nraud (piv txwv li, NPT) rau kev txuas ncaj qha mus rau hauv cov kav dej. Kev khiav hauj lwm feem ntau yog phau ntawv ntawm lub log, nrog rau kev xaiv ntawm lub gearbox kom yooj yim rau kev khiav lag luam. Kev ntsuas siab npog ntau yam chav kawm, suav nrog Chav Kawm 150 txog Chav Kawm 800. Threaded kawg li qub feem ntau muaj qhov ntsuas siab, nrog Chav Kawm 600 thiab Chav Kawm 800 yog cov piv txwv.
Nta thiab Parameters
Lub qhov rooj kawg ntawm lub qhov rooj valve muaj cov qauv yooj yim thiab yooj yim rau nruab. Lub qia valve feem ntau nta ib qho kev sib txuas sab nrauv tsim, tso cai rau pom qhov pom ntawm qhov qhib / kaw txoj haujlwm. Nws qhov kev ua haujlwm kub ntau yog dav, nyob ntawm qhov tshwj xeeb ntawm cov khoom sib khi; Piv txwv li, hlau ntsaws ruaj ruaj tuaj yeem tiv taus qhov kub thiab txias.
Kev xaiv yuav tsum muaj kev lees paub tias lub valve tsim thiab kev sim ua raws li qhov project xav tau cov qauv rau kev siab, kub, thiab kev tshaj tawm. Rau kev siv cov raj xa dej tseem ceeb, kev ntseeg tauScrew End Rooj vag Valveyog ib qho tseem ceeb ntawm kev ua kom muaj kev ncaj ncees.

FAQ rau cov neeg yuav khoom txawv teb chaws
Q1: Tom qab kev teeb tsa lossis lub sijhawm siv, cov dej xau tshwm sim nyob ib puag ncig lub pob valve ntawm lub qhov rooj kawg ntawm lub qhov rooj. Dab tsi tuaj yeem yog qhov laj thawj, thiab yuav tsum tau hais li cas?
Qhov no feem ntau yog packing caj pas to. Tej yam tshwm sim muaj xws li: incompatible packing material for the medium, uneven tightening of the gland follower, los yog kev puas tsuaj rau lub valve qia nto los ntawm corrosion los yog hnav. Txhawm rau hais nws, ua ntej sim ua tib zoo zawm lub caj pas follower. Yog tias tsis muaj txiaj ntsig, nws yog qhov yuav tsum tau ua kom lub cev tsis muaj zog, hloov cov ntim nrog ib hom tsim nyog rau cov kev pabcuam (xws li graphite packing), thiab tshuaj xyuas thiab kho cov kev puas tsuaj rau lub valve qia.
Q2: Manually ua screwed kawg lub qhov rooj li qub tuaj yeem ua haujlwm nyuaj los yog txeeb. Yuav tiv thaiv thiab daws li cas?
Kev ua haujlwm nyuaj tuaj yeem cuam tshuam los ntawm ntau yam: lub valve tuaj yeem daig tom qab lub sijhawm ntev hauv qhov chaw kaw lossis qhib; txawv teb chaws los yog crystallized nruab nrab nyob rau hauv lub raj xa dej tuaj yeem ua rau lub qhov rooj kaw; los yog tsis txaus lubrication yuav ua rau corrosion ntawm threaded ib feem ntawm qia.
Kev tiv thaiv muaj xws li kev ua haujlwm ntawm lub valve me ntsis thiab tu thiab lubricating cov qia threads. Yog tias jamming tau tshwm sim lawm, tsis txhob siv lub zog ntau dhau los tiv thaiv qhov qia. Maj mam tapping lub valve lub cev los yog me ntsis thim rov qab lub handwheel ua ntej maj mam qhib nws yuav pab tau. Rau cov xwm txheej hnyav, yuav tsum tau disassembly rau kev tshuaj xyuas sab hauv thiab ntxuav.
