Umsebenzi oyinhloko we-valve ukuhlukanisa imishini kanye nesistimu yamapayipi, ukulawula ukugeleza, ukuvimbela ukubuyela emuva, ukulawula nokukhipha ingcindezi, kuyisici sokulawula uhlelo lwamapayipi oketshezi, indima ibaluleke kakhulu.Ngakho-ke, ekusetshenzisweni okuvamile kwenqubo kudingeka banake ukugcinwa nokugcinwa kwe-valve.

1. Umsebenzi Wokulungisa Wansuku zonke Wevalvu

I-1.1 Indawo yokugcina i-valve kufanele iphawulwe, kufanele igcinwe ekamelweni elomile lokungenisa umoya, futhi ivimbele iphaseji emikhawulweni yomibili.

1.2 I-valve kufanele ihlolwe njalo, futhi ikhishwe ukungcola endaweni yayo egcotshwe ngamafutha avimbela ukugqwala.

1.3 Ngemuva kokuthi i-valve isifakiwe futhi yasetshenziswa, izolungiswa njalo ukuze kuqinisekiswe ukusebenza kwayo okuvamile.

1.4 Kufanele ahlole ukuthi ivalvu evalekayo iyaguga yini, futhi ngokuya ngezimo zokukhandwa noma ukushintshwa.

1.5 Hlola ukuguga kwentambo ye-stem kanye ne-stem nut trapezoidal, ukupakishwa kuphelelwe yisikhathi futhi akuvumelekile, bese wenza okunye okudingekayo esikhundleni.

1.6 Hlola ukusebenza kokuvala kwevalvu ukuze uqinisekise ukusebenza kwayo.

1.7 Ivalvu kufanele ibe sesimweni esihle sokusebenza, amabhawudo e-flange kanye nabakaki aphelele, intambo iqine, kungabi khona into exegayo.

1.8 Uma isondo lesandla lingekho, kufanele liqedwe ngesikhathi futhi alinakushintshwa yisipanela.

1.9 Ukupakisha indlala akuvunyelwe ukusonteka noma kungabikho igebe eliqinile ngaphambili.

1.10 Uma i-valve isetshenziswa endaweni enzima, esengozini yemvula, iqhwa, uthuli, isihlabathi nokunye ukungcola, kufanele ifake isembozo sokuvikela isiqu se-valve.

1.11 Irula kuvalvu kufanele igcinwe injalo, inembile, icacile, i-valve lead seal, ikepisi.

1.12 Ijazi le-insulation akufanele libe nokucindezeleka, imifantu.

1.13 Amavalvu asebenzayo, gwema ukuwashaya noma ukusekela imithwalo esindayo.

2. Umsebenzi Wokulungisa Umjovo Wamafutha Evalufa

Ukugcinwa kochwepheshe kwe-valve ngaphambi nangemva kokusebenza kwe-welding kudlala indima ebalulekile enkonzweni ye-valve ekukhiqizeni nasekusebenzeni.Ukugcinwa okufanele nokuhlelekile kuzovikela umsebenzi we-valve ngendlela efanele futhi kwandise impilo yesevisi ye-valve.Ukugcinwa kwe-valve kungase kubonakale kulula, kodwa akunjalo.Kuvame ukushaywa indiva izici zomsebenzi.

2.1 Umjovo Wamafutha Evalufa, Naka Inani Lamafutha.

Ngemuva kokuthi i-Grease Gun igcotshwe ngamafutha, opharetha ukhetha i-valve kanye nemodi yokuxhuma umjovo wegrisi ukuze enze umsebenzi womjovo wamafutha.Kunezimo ezimbili: ngakolunye uhlangothi, umjovo wamafutha omncane onganele, indawo yokuvala ngenxa yokuntuleka kwezinto zokugcoba kanye nokuguga okusheshayo.Ngakolunye uhlangothi, umjovo wamafutha ngokweqile, okuholela ekumosheni.Akukho ukubala okunembile kwamandla okuvala ama-valve ahlukene ngokohlobo lwe-valve.Umthamo wokuvala ungabalwa ngokuya ngosayizi we-valve kanye nesigaba, futhi inani elifanele lamafutha lingajovwa ngokunengqondo.

2.2 Umjovo Wamafutha Evalufa, Kufanele Sinake Inkinga Yengcindezi.

Ngesikhathi sokusebenza komjovo, ukucindezela komjovo kushintsha ngendlela evamile.Ingcindezi iphansi kakhulu, ukuvuza kophawu noma ukucindezela kokwehluleka kuphezulu kakhulu, umlomo womjovo wamafutha uvalekile, uhlobo lwamafutha ophawu lwangaphakathi luyaqina noma iringi yophawu nebhola levalvu, ipuleti levalvu ligona lifile.Imvamisa umfutho womjovo wamafutha uphansi kakhulu, umjovo wamafutha ungene ngaphansi kwesikhala sevalvu, uvame ukwenzeka kuvalvu yesango elincane.Ingcindezi yomjovo iphezulu kakhulu, ngakolunye uhlangothi, hlola imbobo yomjovo, njengokuvaleka kwembobo yamafutha gweba isimo ukuze kushintshwe;ngakolunye uhlangothi, ukusetshenziswa koketshezi lokuhlanza ukuthambisa okuphindaphindiwe kokwehluleka kwegrisi yokuvala, kanye nomjovo wokushintshwa kwamafutha amasha.Ngaphezu kwalokho, uhlobo lokuvala kanye nezinto zokuvala, kodwa futhi kuthinta ingcindezi yomjovo, izinhlobo ezahlukene zokuvala zinengcindezi ehlukile yomjovo, icala elijwayelekile lomjovo wophawu oluqinile lwengcindezi iye phezulu kunophawu oluthambile.
