Raws li ib qho tseem ceeb ntawm cov khoom siv dav siv hauv kev thauj cov dej thiab cov txheej txheem tswj cov txheej txheem, kev ua tau zoo thiab kev ntseeg siab ntawm npauj npaim li qub feem ntau nyob ntawm qhov kev loj hlob thiab kev ua kom zoo ntawm lawv cov txheej txheem tsim khoom. Los ntawm kev npaj cov khoom siv raw mus rau kev tshuaj xyuas cov khoom tiav, tus npauj npaim valve tsim cov txheej txheem ua ke nrog ntau theem, suav nrog kev siv tshuab, vuam, kev kho deg, thiab kev sib dhos. Txhua kauj ruam yuav tsum ua raws li cov txheej txheem nruj nruj thiab kev tswj xyuas kom zoo kom ntseeg tau ntev - lub sijhawm ua haujlwm ruaj khov hauv kev ua haujlwm nyuaj.
Cov txheej txheem pib nrog kev xaiv thiab pretreatment ntawm raw cov ntaub ntawv. Lub cev valve feem ntau yog ua los ntawm cam khwb cia los yog forged carbon steel, stainless hlau, los yog hlau alloy los xyuas kom meej lub zog thiab corrosion kuj. Lub phaj npauj npaim tuaj yeem ua los ntawm steel phaj, stainless hlau, los yog tshwj xeeb alloys, thiab nyob ntawm seb cov kev ua hauj lwm tej yam kev mob, nws yog them nrog ib tug mos sealing txheej xws li roj hmab los yog PTFE, los yog siv ib tug hlau hard sealing qauv. Cov ntaub ntawv nyoos nkag mus rau hauv lub Hoobkas yuav tsum tau soj ntsuam cov tshuaj lom neeg muaj pes tsawg leeg thiab kuaj cov cuab yeej cuab yeej; tsuas yog cov uas dhau qhov kev ntsuam xyuas tuaj yeem siv rau kev ua haujlwm kom tsis txhob ua tiav cov khoom tsis ua tiav vim cov khoom siv tsis raug.
Tom qab ntawd, cov txheej txheem thiab txheej txheem pib. Lub valve lub cev dawb paug undergoes ntxhib machining kom tshem tawm cov khoom ntau dhau, ua raws li tig, milling, thiab drilling los tsim cov flange ntsej muag, ntws channel contours, thiab qhov sib txuas. Rau cov cam khwb cia lub cev, kev laus kho mob yuav tsum tau tshem tawm cov kev ntxhov siab sab hauv thiab tiv thaiv deformation thaum lub sij hawm tom ntej los yog siv. Npauj npaim phaj txoj kev tsim muaj xws li txiav, shaping, CNC machining, thiab ntug chamfering kom nws cov geometric qhov ntev thiab streamlined profile raws li hydraulic tsim. Lub valve qia undergoes precision tig thiab kho cua sov kom ua tiav lub zog tsim nyog thiab hnav tsis kam.
Lub machining thiab sib dhos ntawm lub sealing khub yog ib qho tseem ceeb txuas nyob rau hauv cov txheej txheem saw. Rau cov mos mos-foob npauj npaim li qub, cov khoom sib khi yuav tsum tau muab qhwv los yog khi ib ncig ntawm lub phaj npauj npaim thiab kub- nias lossis txias- nias kom ntseeg tau tias qhov sib khi du uas phim lub valve lub cev. Rau qhov nyuaj- foob npauj npaim li qub, cov hlau sealing nto xav tau kev sib tsoo kom tiav kom tiav qhov flatness thiab nto roughness kom ntseeg tau tias qhov tsis tshua muaj paug thaum kaw. Qhov zoo ntawm cov kauj ruam no ncaj qha txiav txim siab qhov kev cia siab ntawm kev sib khi thiab kev pabcuam lub neej ntawm npauj npaim valve.
Vuam thiab sib dhos ua raws li hauv qab. Rau kev sib cais- hom valve lub cev lossis ntau- ntu cov qauv, cov txheej txheem vuam txuam nrog cov khoom siv hauv paus yuav tsum tau siv los ua ke. Tom qab-weld, tsis yog{5}} kuaj kev puas tsuaj (xws li X-ray lossis ultrasonic kuaj) yuav tsum tau ua los kuaj xyuas cov kab nrib pleb thiab qhov tsis xws luag. Tag nrho cov khoom xyaw yog sib sau ua ke hauv ib qho chaw huv. Ua ntej, lub valve qia thiab npauj npaim phaj raug teeb tsa, tom qab ntawd lub valve lub cev kawg lub hau thiab lub nplhaib sib khi yog tsau, thiab cov bolts txuas tau nruj rau qhov ntsuas lub zog kom ruaj khov thiab tsis muaj kev ntxhov siab ntxiv.
Kev kho deg yog ib kauj ruam tseem ceeb hauv kev txhim kho corrosion kuj thiab zoo li zoo. Carbon steel valve lub cev feem ntau sandblasted kom tshem tawm xeb ua ntej coated nrog epoxy primer thiab topcoat. Stainless hlau valve lub cev tuaj yeem raug electrolytic polishing lossis passivation los txhim kho corrosion. Cov txheej txheem txheej yuav tsum tau tswj cov yeeb yaj kiab thickness thiab adhesion kom ruaj khov nyob rau hauv cov huab cua sib txawv thiab qhov chaw tshaj tawm.
Thaum kawg, theem tshuaj ntsuam thiab kuaj pib. Txhua tus npauj npaim valve tau dhau qhov kev sim siab (kev sim lub plhaub thiab kev sib khi) kom paub tseeb tias nws tau xau-dawb thiab cov suab nrov hauv qab lub siab; Tib lub sijhawm, qhov qhib thiab kaw lub zog, kev ua haujlwm yooj yim, thiab qhov tseeb ntawm qhov qhib / kaw qhov qhia tau raug kuaj. Qee cov khoom lag luam kuj xav tau tshwj xeeb siab -kub, qis- kub, lossis kev ntsuas kev tiv thaiv corrosion kom ua tau raws li kev ua haujlwm tshwj xeeb. Tom qab dhau cov kev xeem no, lawv raug suav, ntim, thiab nrog rau cov ntaub ntawv pov thawj zoo ua ntej tawm hauv lub hoobkas.
Zuag qhia tag nrho, kev tsim cov txheej txheem ntawm npauj npaim li qub yog kev sib txuas nruj, kev tsim cov saw hlau, suav nrog kev xaiv cov khoom, molding, sealing processing, vuam sib dhos, kev tiv thaiv nto, thiab kev sim nruj. Tsuas yog los ntawm kev ua raws li cov qauv siab thiab cov kev cai nruj ntawm txhua theem peb tuaj yeem tsim cov npauj npaim li qub nrog kev ua haujlwm ruaj khov, muaj kev nyab xeeb thiab kev ntseeg siab, thiab lub neej ua haujlwm ntev, muab kev lav zoo rau kev lag luam kua dej.
