Ulwazi lokugcinwa kwevalvu

Ukwenzela iiivalveekusebenzeni, zonkeivalveAmalungu kufuneka aphelele kwaye angaguquki. Iibholiti kwiflange kunye nesibiyeli ziyimfuneko, kwaye imisonto kufuneka iphelele kwaye akuvumelekanga ukukhulula. Ukuba i-nut yokuqinisa kwi-handwheel ifunyenwe ikhululekile, kufuneka iqiniswe ngexesha lokuphepha ukukrazula kokudibanisa okanye ukulahlekelwa kwesondo kunye ne-nameplate. Ukuba i-handwheel ilahlekile, ayivumelekanga ukuba ithathe indawo yayo kunye ne-adjustable wrench, kwaye kufuneka igqitywe ngexesha. Idlala lokupakisha alivumelekanga ukuba lijike okanye lingabi nasithuba sokuqina kwangaphambili. Kubaiivalvekwindawo engcoliseka lula yimvula, ikhephu, uthuli, umoya kunye nesanti, isiqu sevalve kufuneka sixhotyiswe ngesigqubuthelo esikhuselayo. Isikali esikwivalvu kufuneka sigcinwe sicocekile, sichanekile kwaye sicacile. Izitywina ezikhokelayo, ii-caps kunye nezixhobo ze-pneumatic zevalve kufuneka zizaliswe kwaye ziphelele. Ijacket yokufakelwa kufuneka ingabi nazibonda okanye iintanda.

Akuvumelekanga ukunkqonkqoza, ukuma okanye ukuxhasa izinto ezinzima kwivalve ekusebenzeni; ingakumbi iivalvu ezingezizo ezentsimbi kunyeiivalve zentsimbizithintelwe ngakumbi.

Ukugcinwa kokungenzi ntoiivalve

Ukugcinwa kweevalvu ezingasebenziyo kufuneka kuqhutywe kunye nezixhobo kunye nemibhobho, kwaye lo msebenzi ulandelayo kufuneka wenziwe:

1. Coca iivalve

I-valve yangaphakathi kufuneka ihlanjululwe kwaye ihlanjululwe ngaphandle kwe-residu kunye nesisombululo samanzi, kwaye ingaphandle yevalve kufuneka ihlanjululwe ngaphandle kokungcola, ioli,

2. Lungelelanisa iivalveiinxalenye

Emva kweivalveilahlekile, impuma ayinakuchithwa ukwenza intshona, kwaye iindawo zevalve kufuneka zixhotyiswe ngokupheleleyo ukwenza iimeko ezilungileyo zokusetyenziswa okulandelayo kwaye ziqinisekise ukubaivalveikwimeko entle.

3. Unyango lwe-anti-corrosion

Khupha ukupakisha kwibhokisi yokufaka ukuthintela ukuhlwa kwegalvanic yeivalveisiqu. Faka i-agent ye-antirust kunye negrisi kwindawo yokutywina yevalve,ivalveisiqu, i-valve stem nut, umphezulu owenziwe ngomatshini kunye namanye amalungu ngokwemeko ethile; iindawo ezipeyintiweyo kufuneka zipeyintwe ngepeyinti enqanda umhlwa.

4. Ukhuseleko

Ukuthintela impembelelo yezinye izinto, ukuphathwa komntu kunye nokuchithwa, ukuba kuyimfuneko, iindawo ezihambayo ze-valve kufuneka zilungiswe, kwaye i-valve kufuneka ifakwe kwaye ikhuselwe.

5.ukugcinwa rhoqo

  Iivalvueziye zingasebenzi ixesha elide kufuneka zihlolwe kwaye zigcinwe rhoqo ukuze kuthintelwe ukubola kunye nomonakalo kwiivalve. Kubaiivalveezihlale zingasebenzi ixesha elide, kufuneka zisetyenziswe emva kokuphumelela uvavanyo loxinzelelo kunye nezixhobo, izixhobo kunye nemibhobho.

Ukugcinwa kwezixhobo zombane

Umsebenzi wokugcinwa kwemihla ngemihla wesixhobo sombane ngokuqhelekileyo ungabi ngaphantsi kanye ngenyanga. Imixholo yogcino yile:

1. Ukubonakala kucocekile ngaphandle kokuqokelela uthuli; isixhobo sikhululekile ekungcolisweni ngumphunga, amanzi kunye neoli.

2. Isixhobo sombane sivalwe kakuhle, kwaye indawo nganye yokutywina kunye nendawo kufuneka igqibelele, yomelele, iqine, kwaye ingavuzi.

3. Isixhobo sombane kufuneka sithanjiswe kakuhle, sifakwe i-oyile ngexesha kwaye njengoko kuyimfuneko, kwaye i-valve stem nut kufuneka ifakwe i-lubricated.

4. Inxalenye yombane kufuneka ibe kwimeko efanelekileyo, kwaye ugweme ukukhukuliseka komswakama kunye nothuli; ukuba imanzi, sebenzisa i-500V megohmmeter ukulinganisa ukunyanzeliswa kwe-insulation phakathi kwazo zonke iindawo eziphetheyo ngoku kunye negobolondo, kwaye ixabiso akufanele libe ngaphantsi kwe-o. Yokomisa.

5. Ukutshintsha okuzenzekelayo kunye ne-thermal relay akufanele kuhambe, ukukhanya kwesalathisi kubonisa ngokuchanekileyo, kwaye akukho ukungaphumeleli kokulahleka kwesigaba, isiphaluka esifutshane okanye isiphaluka esivulekileyo.

6. Ubume bokusebenza kwesixhobo sombane siqhelekile, kwaye ukuvulwa nokuvalwa kuguquguquka.

Ukugcinwa kwezixhobo zomoya

Umsebenzi wemihla ngemihla wokugcinwa kwesixhobo somoya awukho ngaphantsi kanye ngenyanga. Imixholo ephambili yolondolozo yile:

1. Ukubonakala kucocekile ngaphandle kokuqokelela uthuli; isixhobo akufanele singcoliswe ngumphunga wamanzi, amanzi kunye neoli.

2. Ukutywinwa kwesixhobo somoya kufuneka kube kuhle, kwaye iindawo zokutywina kunye namanqaku kufuneka aphelele kwaye aqine, aqine kwaye angonakaliswe.

3. Isixhobo sokusebenza semanyuwali kufuneka sithanjiswe kakuhle kwaye sivuleke kwaye sivaleke ngokuguquguqukayo.

4. I-inlet kunye ne-outlet gas joints of the cylinder ayivumelekanga ukuba yonakaliswe; zonke iindawo ze-cylinder kunye ne-air piping system kufuneka zihlolwe ngokucophelela, kwaye kungabikho ukuvuza okuchaphazela ukusebenza.

5. Umbhobho awuvumelekanga ukuba utshiswe, i-annunciator kufuneka ibe yimeko efanelekileyo, ukukhanya kwesalathisi se-annunciator kufuneka kube kwimeko efanelekileyo, kunye nentambo yokudibanisa ye-annunciator ye-pneumatic okanye i-annunciator yombane kufuneka ihambelane ngaphandle kokuvuza.

6. Iivalves kwisixhobo somoya kufuneka sibekwimeko elungileyo, singavuzi, sivuleke ngokulula, kwaye sibe nokuhamba komoya okumtyibilizi.

7. Isixhobo sonke se-pneumatic kufuneka sibe kwimeko yokusebenza eqhelekileyo, sivuleke kwaye sivaleke ngokuguquguqukayo.
