Lub hauv paus tswj xyuas thaum lub sijhawm ua haujlwm valve yog raws li hauv qab no:
① Khaws sab nrauv thiab ua haujlwm ntawm lub valve kom huv si thiab tiv thaiv kev ncaj ncees ntawm cov xim valve. Qhov saum npoo ntawm lub valve, cov xov trapezoidal ntawm lub qia thiab lub valve qia txiv ntoo, zawv zawg qhov chaw ntawm lub valve qia txiv ntoo thiab lub bracket, thiab lub zog, cab iav thiab lwm qhov chaw yog nquag tso cov plua plav, roj ntau. , thiab nruab nrab residues, uas ua rau hnav thiab corrosion rau lub valve. Yog li ntawd, lub valve yuav tsum tau ua kom huv si txhua lub sijhawm. Cov plua plav dav dav ntawm lub valve yog tsim rau txhuam thiab compressed cua tshuab, thiab tuaj yeem txhuam nrog tooj liab hlau txhuam kom txog thaum lub tshuab ua haujlwm thiab qhov sib txuam ntawm qhov sib xyaw ua kom pom cov xim hlau thiab cov xim pleev xim pom cov xim qub ntawm cov xim. Lub tshuab nqus tsev vacuum yuav tsum muaj lub luag haujlwm rau tus neeg mob siab thiab tshawb xyuas tsawg kawg ib zaug ua haujlwm; tsis tu ncua qhib lub qhov dej ntws tawm thiab cov xov hauv qab ntawm lub tshuab nqus dej rau cov dej ntws tawm, lossis tsis tu ncua disassemble thiab yaug kom tsis txhob muaj av los ntawm clogging lub valve.
② Khaws lub valve lubricated, lub valve trapezoidal threads, zawv zawg qhov chaw ntawm lub valve qia txiv ntseej thiab lub bracket, txoj hauj lwm bearing, meshing qhov chaw ntawm lub iav thiab cov cab iav, thiab lwm yam khoom sib txuam yuav tsum tau lubrication zoo kom txo tau kev sib nrig sib. kev sib txhuam thiab zam kev hnav khaub ncaws. Rau qhov chaw uas tsis muaj roj khob lossis roj nozzles, uas yooj yim puas los yog poob thaum lub sijhawm ua haujlwm, lub lubrication system yuav tsum tau kho thiab nruab kom ntseeg tau tias cov roj Circuit Court tsis thaiv.
Lubricated qhov chaw yuav tsum tau refueled tsis tu ncua raws li tej yam kev mob. Valves uas nquag qhib thiab muaj qhov kub thiab txias yog tsim rau refueling ib lub lim tiam mus rau ib hlis; li qub uas tsis nquag qhib thiab muaj qhov kub thiab txias tuaj yeem muaj lub voj voog refueling ntev dua. Lubricants muaj xws li roj cav, butter, molybdenum disulfide thiab graphite. Cov roj cav tsis haum rau lub siab kub li qub; butter tsis haum ib yam, vim lawv yuav yaj thiab ntws tawm vim qhov kub thiab txias. High-temperature li qub yog tsim rau ntxiv molybdenum disulfide thiab so graphite hmoov. Yog tias butter thiab lwm cov roj siv rau lubricated qhov chaw raug rau sab nraud, xws li cov xov trapezoidal thiab nruab nrab ntawm cov hniav, nws yooj yim heev kom kis tau cov plua plav, thaum molybdenum disulfide thiab graphite hmoov tsis yooj yim kom muaj plua plav thiab lubrication. cov nyhuv yog zoo dua li butter. Graphite hmoov tsis yog ib qho yooj yim mus thov ncaj qha, thiab siv tau nrog me ntsis cav roj los yog dej los ua ib tug muab tshuaj txhuam.
Lub ntsaws valve nrog roj filling foob yuav tsum tau ntim cov roj thaum lub sijhawm teev tseg, txwv tsis pub nws yooj yim hnav thiab xau.
③ Khaws ob qhov chaw ua kom tiav thiab tsis zoo. Lub bolts ntawm flange thiab bracket yuav tsum ua kom tiav thiab tag nrho buckled, thiab tsis pub looseness. Yog hais tias lub fastening txiv ntseej ntawm lub handwheel yog xoob, nws yuav tsum tau nruj me ntsis raws sij hawm kom tsis txhob hnav cov kev twb kev txuas los yog poob lub handwheel. Tom qab lub handwheel ploj lawm, nws tsis raug tso cai los hloov lub handwheel nrog lub flap, thiab nws yuav tsum tau hloov raws sij hawm. Lub packing siab sib txawv tsis pub yuav skewed los yog tsis pre-tightening clearance. Nyob rau hauv ib qho chaw uas yooj yim los nag, daus, plua plav thiab lwm yam av, lub qia valve yuav tsum tau nruab nrog lub npog tiv thaiv. Qhov ntsuas ntawm lub valve yuav tsum khaws cia kom zoo thiab raug. Lub valve lub taub hau foob, lub hau, pneumatic accessories, thiab lwm yam yuav tsum ua kom tiav thiab tsis zoo. Lub tsho rwb thaiv tsev yuav tsum tsis muaj dents thiab tawg.
Tsis tas li ntawd, nws tsis raug tso cai rau khob, txhawb nqa cov khoom hnyav lossis sawv ntawm lub valve kom tsis txhob qias neeg lub valve thiab ua rau lub valve puas. Tshwj xeeb tshaj yog non-metallic mesh qhov rooj thiab cam khwb cia hlau li qub, nws yog ntau taboo.
Tswj xyuas txhua hnub ntawm cov khoom siv hluav taws xob. Kev saib xyuas ntawm cov cuab yeej hluav taws xob feem ntau tsis pub tsawg dua ib hlis ib zaug. Cov ntsiab lus ntawm kev saib xyuas muaj xws li: qhov chaw yuav tsum huv si, tsis muaj plua plav paug, cov cuab yeej tsis muaj dej qab zib, dej, thiab roj; lub sealing nto thiab cov ntsiab lus yuav tsum ruaj thiab nruj. Tsis muaj dej ntws; lubrication qhov chaw yuav tsum tau oiled raws li yuav tsum tau, thiab lub valve txiv ntseej yuav tsum tau greased; Qhov hluav taws xob yuav tsum tsis muaj zog, tsis muaj theem tsis ua haujlwm, qhov hloov pauv tsis siv neeg thiab thermal relay yuav tsum tsis txhob mus, thiab qhov taw qhia lub teeb yuav tsum tso saib kom raug.
