3. Kev sib tsoo ntawm qhov chaw sealing

Yog vim li cas:

(1) Sealing nto sib tsoo tsis sib xws, tsis tuaj yeem tsim txoj kab ze;

(2) Sab saum toj nruab nrab ntawm kev sib txuas ntawm lub valve qia thiab qhov kaw yog raug tshem tawm, lossis hnav;

(3) Lub qia valve yog khoov los yog sib dhos tsis raug, kom cov khoom kaw tau skewed lossis tawm ntawm qhov chaw;

(4) Kev xaiv tsis raug ntawm sealing nto khoom zoo los yog xaiv valve raws li kev ua haujlwm.

Txoj kev tu:

(1) Xaiv cov khoom thiab hom gasket kom raug raws li kev ua haujlwm;

(2) Kev kho kom zoo, ua haujlwm zoo;

(3) Lub ntsia liaj qhov rooj yuav tsum sib npaug thiab symmetrically screwed, thiab torque wrench yuav tsum tau siv yog tias tsim nyog.Lub pre-tightening quab yuam yuav tsum tau raws li qhov yuav tsum tau thiab yuav tsum tsis txhob loj los yog me me.Flange thiab xov txuas yuav tsum muaj qhov sib txawv ua ntej nruj;

(4) Gasket los ua ke yuav tsum tau raws li qhov tseeb, lub zog sib xws, gasket tsis pub rau lap thiab siv ob chav gasket;

(5) Qhov zoo li qub sealing nto corrosion, kev puas tsuaj, kev ua haujlwm zoo tsis siab, yuav tsum tau kho, sib tsoo, tshuaj xyuas xim, kom qhov zoo li qub sealing nto ua tau raws li qhov xav tau;

(6) Lub installation ntawm gasket yuav tsum tau them sai sai rau kev ntxuav, sealing nto yuav tsum yog kerosene ntshiab, gasket yuav tsum tsis txhob poob.

4. Cov dej ntws tawm ntawm lub nplhaib sib txuas

Yog vim li cas:

(1) Lub nplhaib sealing tsis nruj nruj

(2) Sealing nplhaib thiab lub cev vuam, nto vuam zoo tsis zoo;

(3) Sealing nplhaib txuas xov, ntsia hlau, lub nplhaib siab xoob;

(4) Lub nplhaib sealing txuas thiab corroded.

Txoj kev tu:

(1) Cov dej xau ntawm lub sealing dov yuav tsum tau ntim nrog cov nplaum thiab tom qab ntawd dov thiab kho;

(2) Lub nplhaib sealing yuav tsum tau kho raws li qhov tshwj xeeb vuam.Yog tias qhov chaw surfacing tsis tuaj yeem kho, qhov qub surfacing yuav tsum raug tshem tawm;

(3) Tshem tawm cov ntsia hlau, ntxuav lub nplhaib siab, hloov cov khoom puas, zom cov sealing thiab txuas lub rooj zaum ze, thiab rov ua dua.Cov khoom puas los ntawm corrosion tuaj yeem kho los ntawm vuam, sib txuas, thiab lwm yam.

(4) Lub nplhaib sealing kev sib txuas nto yog corroded, uas tuaj yeem kho tau los ntawm kev sib tsoo, kev sib txuas, thiab lwm yam, thiab lub nplhaib sealing yuav tsum tau hloov thaum nws tsis tuaj yeem kho.

5.Leakage ntawm lub cev valve thiab valve npog:

Yog vim li cas:

(1) cam khwb cia hlau casting zoo tsis siab, lub valve lub cev thiab lub valve npog lub cev muaj cov xuab zeb qhov, lub koom haum xoob, slag suav nrog thiab lwm yam tsis xws luag;

(2) Khov tawg;

(3) Cov vuam tsis zoo, muaj cov slag suav nrog, tsis yog vuam, kev ntxhov siab tawg thiab lwm yam tsis xws luag;

(4) Lub cam khwb cia hlau valve puas lawm tom qab raug ntaus los ntawm cov khoom hnyav.

Txoj kev tu:

(1) Txhim kho qhov zoo ntawm casting, thiab ua qhov kev ntsuam xyuas lub zog nruj raws li cov cai ua ntej kev teeb tsa;

(2) Rau li qub nrog kub qis dua 0 ° thiab 0 °, kev txuag hluav taws xob lossis kev sib xyaw yuav tsum tau nqa tawm, thiab dej yuav tsum raug cais tawm ntawm cov khoom siv uas tsis siv;

(3) Lub vuam ntawm lub valve lub cev thiab lub valve npog tsim los ntawm vuam yuav tsum tau ua raws li cov txheej txheem vuam cuam tshuam, thiab kev kuaj xyuas qhov tsis zoo thiab lub zog yuav tsum tau ua tom qab vuam;

(4) Nws yog txwv tsis pub thawb cov khoom hnyav rau ntawm lub valve, thiab nws tsis raug tso cai rau cuam tshuam cov hlau thiab cov hlau tsis muaj hlau nrog ib txhais tes rauj.
