1. Txheeb xyuas qhov ua rau ntawm qhov xau
Ua ntej ntawm tag nrho cov, nws yog ib qho tsim nyog yuav tau kuaj xyuas qhov ua rau ntawm qhov xau. Leaks tuaj yeem tshwm sim los ntawm ntau yam, xws li frayed sealing nto, deterioration ntawm cov ntaub ntawv, installation tsis raug, neeg ua hauj lwm yuam kev, los yog media corrosion. Lub hauv paus ntawm cov dej xau tuaj yeem raug txheeb xyuas sai sai los ntawm kev siv cov cuab yeej tshuaj xyuas thiab cov hau kev, xws li ultrasonic leak detectors, kev soj ntsuam pom, thiab kev ntsuas siab, los muab lub hauv paus muaj zog rau kev kho tom ntej.
Qhov thib ob, kev daws teeb meem rau qhov sib txawv to
1. Cov khoom kaw tau poob tawm thiab ua rau cov dej xau
Ua rau: Kev ua haujlwm tsis zoo ua rau cov khoom kaw tau daig lossis dhau ntawm qhov chaw tuag sab saud, thiab kev sib txuas yog puas thiab tawg; Cov khoom siv ntawm cov khoom sib txuas uas tau xaiv tsis raug, thiab nws tsis tuaj yeem tiv taus corrosion ntawm nruab nrab thiab hnav ntawm cov tshuab.
Kev daws: Siv lub valve kom raug kom tsis txhob muaj zog ntau dhau ua rau cov khoom kaw raug daig lossis puas; Tsis tu ncua xyuas seb qhov kev sib txuas ntawm lub kaw-tawm thiab lub valve qia yog ruaj, thiab hloov qhov kev sib txuas hauv lub sijhawm yog tias muaj corrosion lossis hnav; Xaiv cov khoom ntawm lub connector nrog zoo corrosion kuj thiab hnav tsis kam.
2. Cov dej ntws tawm ntawm qhov sib txuas ntawm lub nplhaib sib khi
Yog vim li cas: Lub nplhaib sealing tsis nruj dov; Cov vuam tsis zoo ntawm lub nplhaib sealing thiab lub cev; Seal threads thiab screws yog xoob los yog corroded.
Kev daws: Siv cov nplaum los kho qhov chaw dov ntawm lub nplhaib sealing; Kho thiab rov welding qhov tsis xws luag; Lub sij hawm hloov ntawm corroded los yog puas threads thiab screws; Re-weld lub foob junction raws li specification.
3. Cov dej ntws tawm ntawm lub cev valve thiab lub kaus mom
Yog vim li cas: Qhov zoo ntawm cov hlau castings tsis yog siab, thiab muaj qhov tsis xws li cov xuab zeb qhov, cov ntaub so ntswg xoob, thiab cov slag suav nrog; hnub khov tawg; Kev vuam tsis zoo, nrog rau qhov tsis xws luag xws li slag suav nrog, unwelding, kev ntxhov siab tawg, thiab lwm yam.; Lub valve tau puas lawm tom qab raug ntaus los ntawm ib qho khoom hnyav.
Kev daws: Txhim kho qhov zoo ntawm casting thiab ua qhov kev xeem lub zog ua ntej kev teeb tsa; Lub valve uas tsis tshua muaj kub yuav tsum tau insulated los yog kub-sib xyaw, thiab lub valve uas tsis siv yuav tsum tau drained ntawm cov dej stagnation; Weld raws li cov txheej txheem kev ua haujlwm vuam, thiab ua kom pom qhov tsis zoo thiab kev ntsuas lub zog; Nws yog txwv tsis pub thawb thiab tso cov khoom hnyav rau ntawm lub valve, thiab tsis txhob tsoo cov cam khwb cia hlau thiab cov khoom tsis yog xim hlau nrog ib txhais tes rauj.
4. Kev sib tsoo ntawm qhov chaw sealing
Ua rau: kev sib tsoo tsis sib xws ntawm lub sealing nto; Kev sib txuas ntawm cov qia thiab qhov kaw yog dangling, tsis tsim nyog lossis hnav; khoov los yog misassembled stems; Kev xaiv tsis raug ntawm cov khoom siv sealing nto.
Kev daws: raug xaiv cov khoom siv gasket thiab hom raws li kev ua haujlwm; Ua tib zoo kho lub valve kom ua haujlwm zoo; Tighten tus ntsia liaj qhov rooj sib npaug thiab symmetrically, thiab siv lub torque ciaj ntswj kom ntseeg tau tias lub preload ua tau raws li qhov yuav tsum tau ua; Kho, sib tsoo thiab xim tshuaj xyuas ntawm qhov chaw sib khi zoo li qub kom ntseeg tau tias lawv ua tau raws li qhov yuav tsum tau ua; Ua tib zoo saib xyuas thaum txhim kho lub gasket kom tsis txhob gasket poob rau hauv av.
5. Cov dej ntws tawm ntawm qhov muab tub lim
Yog vim li cas: xaiv tsis raug ntawm muab tub lim; Kev ntim khoom tsis raug; kev laus ntawm fillers; Qhov tseeb ntawm qia tsis siab; Cov qog, bolts thiab lwm qhov chaw raug puas tsuaj.
Kev daws: Xaiv cov khoom ntim khoom tsim nyog thiab hom raws li kev ua haujlwm; Kev txhim kho kom zoo ntawm packing raws li specifications; Hloov cov laus thiab cov khoom puas lawm hauv lub sijhawm; straightening, kho los yog hloov khoov, hnav stems; Cov qog uas puas lawm, bolts thiab lwm yam khoom yuav tsum tau kho lossis hloov lub sijhawm; Ua raws li cov txheej txheem kev khiav hauj lwm thiab khiav lub valve ntawm qhov ceev thiab lub zog ib txwm muaj.
3. Kev tiv thaiv
1. Kev tshuaj xyuas thiab kev saib xyuas tsis tu ncua: Tsim ib qho kev npaj kho kom tsim nyog raws li qhov zaus ntawm kev siv lub valve thiab qhov chaw ua haujlwm. Nrog rau kev tu lub puab sab hauv thiab sab nrauv ntawm lub valve, xyuas seb cov fasteners puas xoob, lubricating qhov kis tau tus mob, thiab lwm yam. Los ntawm kev saib xyuas kev tshawb fawb, cov teeb meem muaj peev xwm tuaj yeem pom thiab daws tau nyob rau lub sijhawm kom ntev lub neej kev pab cuam ntawm lub valve.
2. Xaiv cov khoom zoo li qub: Yuav kom txo qis txoj kev pheej hmoo ntawm lub valve, nws yog ib qho tsim nyog yuav tau xaiv cov khoom zoo valve. Los ntawm kev xaiv cov khoom siv, cov qauv tsim rau cov txheej txheem ntau lawm, cov khoom siv valve raug tswj nruj me ntsis kom ntseeg tau tias qhov ua tau zoo tshaj plaws. Kev khiav hauj lwm thiab kev teeb tsa kom raug: Ua raws li cov txheej txheem kev khiav hauj lwm thiab khiav lub valve kom raug. Thaum lub sij hawm lub installation txheej txheem, xyuam xim rau lub installation txoj hauj lwm thiab kev taw qhia ntawm lub valve kom paub meej tias lub valve yuav qhib thiab kaw ib txwm. Nyob rau tib lub sijhawm, tsis txhob siv lub zog ntau dhau ntawm lub valve lossis ntaus lub valve.
