Ukulungiswa kwevalvu

Kuma-valve asebenzayo, zonke izingxenye zama-valve kufanele ziphelele futhi zingashintshi. Ama-bolts aku-flange kanye ne-bracket abalulekile, futhi izintambo kufanele zingashintshi futhi akukho ukukhululeka okuvunyelwe. Uma i-fastening nut esondweni lesandla itholakala ikhululekile, kufanele iqiniswe ngesikhathi ukuze kugwenywe ukuklwebheka kwejoyinti noma ukulahleka kwe-handwheel kanye ne-nameplate. Uma i-handwheel ilahlekile, ayivunyelwe ukuyifaka esikhundleni se-wrench elungisekayo, futhi kufanele iqedwe ngesikhathi. I-packing gland ayivunyelwe ukugoba noma ingabi nesikhala sokuqinisa ngaphambi kwesikhathi. Kuma-valve endaweni engcoliswa kalula yimvula, iqhwa, uthuli, umoya nesihlabathi, isiqu se-valve kufanele sifakelwe isembozo esivikelayo. Isikali ku-valve kufanele sigcinwe singashintshi, sinembile futhi sicacile. Izimbozo zomthofu, izigqoko kanye nezesekeli ze-pneumatic ze-valve kufanele ziphelele futhi zingashintshi. Ijakethi yokushisa akufanele ibe nama-dents noma imifantu.

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

Ukugcinwa kwamavalvu angasebenzi

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. Qondanisa izingxenye zevalvu

Ngemva kokuba ivalvu ingekho, impumalanga ayikwazi ukuhlukaniswa ukuze kwenziwe intshonalanga, futhi izingxenye zevalvu kufanele zihlonyiswe ngokugcwele ukuze kudalwe izimo ezinhle zokusetshenziswa okulandelayo nokuqinisekisa ukuthi ivalvu isesimweni 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, isiqu sevalvu, i-nut yesiqu sevalvu, 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.ukugcinwa okuvamile

Amavalvu abengasebenzi isikhathi eside kufanele ahlolwe futhi agcinwe njalo ukuze kuvinjelwe ukugqwala kanye nomonakalo kuvalvu. Kumavalvu abengasebenzi isikhathi eside kakhulu, kufanele asetshenziswe ngemuva kokudlula ukuhlolwa kokucindezela kanye nemishini, amadivayisi, 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. Amavalvu kudivayisi yomoya kufanele abe sesimweni esihle, angabi nokuvuza, avuleke kalula, futhi abe nomoya ogeleza kahle.

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

Ukungabaza okwengeziwe noma imibuzo yabantu abahleli phansi abaqinileivalvu yebhabhathane, ivalvu yesango, ungaxhumana noI-TWS VALVE.
