Ulwazi lokugcinwa kwama-valve

Okweamavalvuisebenza, konkeivalvuizingxenye kufanele ziphelele futhi zingabi nalutho. Amabhawodi aku-flange kanye ne-bracket abalulekile, futhi imicu kufanele ingabi nalutho futhi akuvunyelwe ukuxega. Uma i-fastening nut esondweni lesandla itholakala ikhululekile, kufanele iqiniswe ngesikhathi ukuze kugwenywe ukuklwebheka kwejoyinti noma ukulahleka kwesondo lesandla kanye ne-nameplate. Uma isondo lesandla lilahlekile, akuvunyelwe ukulishintsha nge-wrench elungisekayo, futhi kufanele liqedwe ngesikhathi. I-packing gland ayivunyelwe ukugoba noma ingabi nesikhala sokuqinisa.amavalvuEndaweni engcoliswa kalula yimvula, iqhwa, uthuli, umoya nesihlabathi, isiqu sevalvu kufanele sifakelwe isembozo esivikelayo. Isikali esisevalvuni kufanele sigcinwe siphelele, sinembile futhi sicacile. Izivalo zomthofu, izigqoko kanye nezesekeli zomoya zevalvu kufanele zibe ziphelele futhi ziphelele. Ijazi lokuvikela akufanele libe namaqhubu noma imifantu.

Akuvunyelwe ukungqongqoza, ukuma noma ukusekela izinto ezisindayo ku-valve esebenza; ikakhulukazi ama-valve angewona awensimbi kanyeamavalvu ensimbi ephonswezivinjelwe nakakhulu.

Ukugcinwa kokungenzi luthoamavalvu

Ukugcinwa kwamavalvu angasebenzi kufanele kwenziwe kanye nemishini namapayipi, futhi umsebenzi olandelayo kufanele wenziwe:

1. Hlanzaivalvu

Ingaphakathi levalvu kufanele lihlanzwe futhi lihlanzwe ngaphandle kwezinsalela kanye nesixazululo samanzi, kanti ingaphandle levalvu kufanele lisulwe kahle ngaphandle kokungcola, uwoyela,

2. Qondanisaivalvuizingxenye

Ngemva kwe-ivalvuuma ingekho, impumalanga ayikwazi ukuhlukaniswa ukuze kwenziwe intshonalanga, futhi izingxenye zevalvu kufanele zihlonyiswe ngokugcwele ukudala izimo ezinhle zokusetshenziswa okulandelayo nokuqinisekisa ukuthiivalvuisesimweni esihle.

3. Ukwelashwa kokulwa nokugqwala

Khipha ukupakisha ebhokisini lokugcwalisa ukuze uvimbele ukugqwala kwe-galvanic kwe-ivalvuisiqu. Faka i-ejenti yokulwa nokugqwala bese ugcoba endaweni yokuvala ivalvu,ivalvuisiqu, i-valve stem nut, indawo efakwe umshini kanye nezinye izingxenye ngokwesimo esithile; izingxenye ezipendiwe kufanele zipendwe ngopende wokulwa nokugqwala.

4. Ukuvikelwa

Ukuze kuvinjelwe ukushayisana kwezinye izinto, ukuphathwa nokuhlukaniswa okwenziwe ngumuntu, uma kudingeka, izingxenye ezinyakazayo zevalvu kufanele zilungiswe, futhi ivalvu kufanele ipakishwe futhi ivikelwe.

5.ukulungiswa okuvamile

  Amavalvuesezihlale isikhathi eside zingasebenzi kufanele zihlolwe futhi zigcinwe njalo ukuze kuvinjelwe ukugqwala kanye nomonakalo ku-ivalvu. Ngobaamavalvuesezihlale isikhathi eside zingasebenzi, kufanele zisetshenziswe ngemva kokuphumelela ukuhlolwa kokucindezela kanye nemishini, amadivayisi, kanye namapayipi.

Ukugcinwa kwamadivayisi kagesi

Umsebenzi wokulungisa wansuku zonke wedivayisi kagesi ngokuvamile awungaphansi kwesisodwa ngenyanga. Okuqukethwe kokulungisa yile:

1. Ukubukeka kuhlanzekile ngaphandle kokuqongelela uthuli; idivayisi ayinayo ingcoliso ebangelwa umusi, amanzi kanye namafutha.

2. Idivayisi kagesi ivalwe kahle, futhi indawo ngayinye yokuvala kanye nephuzu kufanele kuphelele, kuqine, kuqine, futhi kungavuzi.

3. Idivayisi kagesi kufanele igcotshwe kahle, igcotshwe ngamafutha ngesikhathi futhi njengoba kudingeka, futhi i-valve stem nut kufanele igcotshwe.

4. Ingxenye kagesi kufanele ibe sesimweni esihle, futhi igweme ukuguguleka komswakama nothuli; uma imanzi, sebenzisa i-megohmmeter engu-500V ukukala ukumelana kokushisa phakathi kwazo zonke izingxenye ezithwala ugesi kanye negobolondo, futhi inani akufanele libe ngaphansi kuka-o. Ukomisa.

5. Iswishi ezenzakalelayo kanye ne-thermal relay akufanele kukhubeke, ukukhanya kwesikhombisi kubonakala kahle, futhi akukho ukwehluleka kokulahlekelwa yisigaba, i-short circuit noma i-open circuit.

6. Isimo sokusebenza sedivayisi kagesi sijwayelekile, futhi ukuvulwa nokuvalwa kuyaguquguquka.

Ukugcinwa kwamadivayisi omoya

Umsebenzi wokulungisa wansuku zonke wedivayisi yomoya ngokuvamile awungaphansi kwesisodwa ngenyanga. Okuqukethwe okuyinhloko kokulungisa yile:

1. Ukubukeka kuhlanzekile ngaphandle kokuqongelela uthuli; idivayisi akufanele ingcoliswe umhwamuko wamanzi, amanzi kanye namafutha.

2. Ukuvalwa kwedivayisi yomoya kufanele kube kuhle, futhi izindawo zokuvala kufanele ziphelele futhi ziqine, ziqine futhi zingalimali.

3. Indlela yokusebenza ngesandla kufanele igcotshwe kahle futhi ivuleke futhi ivalwe kalula.

4. Amalunga egesi yokungena kanye neyokuphuma kwesilinda awavunyelwe ukuba onakale; zonke izingxenye zesilinda kanye nohlelo lwamapayipi omoya kufanele zihlolwe ngokucophelela, futhi akumelwe kube khona ukuvuza okuthinta ukusebenza.

5. Ipayipi alivunyelwe ukucwiliswa, i-annunciator kufanele ibe sesimweni esihle, isibani senkomba se-annunciator kufanele sibe sesimweni esihle, futhi intambo yokuxhuma ye-annunciator yomoya noma i-annunciator kagesi kufanele ihlale ingavuthi.

6. IivalvuAma-s kudivayisi yomoya kufanele abe sesimweni esihle, angabi nokuvuza, avuleke kalula, futhi abe nomoya ogelezayo kahle.

7. Lonke idivayisi yomoya kufanele ibe sesimweni sokusebenza esijwayelekile, ivuleke futhi ivalwe kalula.
