Vim nws cov qauv yooj yim, kev teeb tsa yooj yim, lub teeb yuag, thiab qhib thiab kaw sai,npauj npaim li qubyog siv dav hauv kev lag luam thiab pej xeem nruab nrab thiab qis siab pipeline systems. Yog tias lub valve siv dav dav no tuaj yeem ua rau nws lub neej ua haujlwm ntev dua, nws yuav tsim ntau yam txiaj ntsig rau cov neeg siv butterfly valve.
Kev xaiv lub valve npauj npaim kom raug yog qhov yuav tsum tau ua ua ntej rau lub neej ua haujlwm ntawm lub valve npauj npaim thaum xaiv kom raug. Cov valve npauj npaim sib txawv siv rau ntau lub sijhawm sib txawv, thiab qhov no kuj yog qhov laj thawj rau txhua yam kev qhia tshwj xeeb thiab cov qauv ntawm cov valve npauj npaim. Thaum xaiv hom, koj tsis tuaj yeem siv cov valve npauj npaim kim heev yam tsis paub. Ntau yamnpauj npaim li qubntawm cov lus qhia sib txawv yog qhov tsim nyog, yog li tsis muaj qhov zoo lossis qhov phem ntawm lawv, tsuas yog tsim nyog lossis tsis tsim nyog. Cov xwm txheej ua haujlwm tsim nyog rau kev siv yog qhov zoo tshaj plaws.
Kev teeb tsa tsim nyog: Txawm hais tias kev teeb tsa lub valve npauj npaim yooj yim, nws tseem tsis tuaj yeem saib xyuas tau. Txhua qhov kev puas tsuaj, khoov, lossis deformation ntawm cov khoom yuav cuam tshuam rau qhov cuam tshuam ntawm kev siv. Kev siv kom raug kuj tseem ceeb. Piv txwv li, koj tsis tuaj yeem siv lub afterburner lossis torque wrench thaum qhib thiab kaw lub valve npauj npaim tes. Feem ntau hais lus, tus qauv tsim yuav tsum tsim nyog. Thaum peb tsis tuaj yeem qhib thiab kaw lub valve npauj npaim tau yooj yim, yuav ua li cas txuas lub neej ntawm lub valve npauj npaim? Qhov laj thawj yuav tsum tau kuaj xyuas ua ntej, kev kaw yuam yuav ua rau lub neej ua haujlwm ntawm lub valve luv dua.
Tsim Tsim Nyog Thaum siv rau hauv qee qhov chaw ua haujlwm tshwj xeeb, tus neeg siv tuaj yeem sib tham txog txoj kev npaj tsim qauv tsim nyog nrog lub chaw tsim khoom. Yog tias cov khoom lag luam ib txwm muaj tseem siv, nws yuav tsis zoo rau kev siv cov npauj npaim valve.
Hauv cov kav dej, yog tias xav tau kev tswj chaw taws teeb lossis kaw ntau zaus, feem ntau xaiv cov li qub hluav taws xob thiab cov li qub pneumatic. Vim tias qhib thiab kaw ntau zaus thiab cov xwm txheej ua haujlwm tshwj xeeb, kev kho tshwj xeeb feem ntau xav tau.npauj npaim li qubnrog cov pas nrig polished tsis tuaj yeem ntsia ncaj qha nrog cov actuators valve. Feem ntau, cov kev kho mob hauv qab no yuav tsum tau ua: lub qia valve yog thickened kom tiv thaiv lub qia valve los ntawm kev khoov thiab deforming vim kev co thaum lub sijhawm qhib thiab kaw; lub kaw lus ntim khoom siv cov txheej txheem xws li kev teeb tsa spacer rings, kev xav txog kev them nyiaj springs, thiab kev teeb tsa O-rings kom ntev lub kaw lus ntim khoom hauv qab qhov xwm txheej ua haujlwm no Kev Pabcuam Lub Neej
Cov saum toj no yog ob peb qhov kev paub dhau los uas tau sau los ntawm cov txheej txheem ntawm kev tsim thiab siv lub valve, vam tias yuav muab kev pab zoo rau cov neeg siv valve uas xav tau.
