Amavalvuawasetshenziswa nje kuphela ezimbonini ezihlukahlukene, kodwa futhi asebenzisa izindawo ezihlukene, futhi amanye ama-valve ezindaweni zokusebenza ezinokhahlo ajwayele ukuba nezinkinga. Njengoba ama-valve eyimishini ebalulekile, ikakhulukazi kwamanye ama-valve amakhulu, kuba nzima kakhulu ukuwakhanda noma ukuwashintsha uma sekunenkinga. Ngakho-ke, kubaluleke kakhulu ukwenza umsebenzi omuhle wokunakekela nokunakekela nsuku zonke. Ake sibheke amanye amathiphu mayelana nokugcinwa kwama-valve.
1. Ukugcinwa kanye nokuhlolwa kwansuku zonke kweama-valve
1. I-valve kufanele igcinwe ekamelweni elomile nelingena umoya, futhi zombili iziphetho zephaseji kufanele zivalwe.
2. Amavalvuegcinwe isikhathi eside kufanele ihlolwe njalo, ukungcola kufanele kususwe, futhi amafutha e-anti-rust kufanele ahlanganiswe endaweni yokucubungula.
3. Ngemuva kokufakwa, ukuhlolwa okujwayelekile kufanele kwenziwe, futhi izinto zokuhlola eziyinhloko yilezi:
(1) Ukugqokwa kwendawo yokuvala.
(2) Ukugqokwa kwentambo ye-trapezoidal yesiqu ne-stem nut.
(3) Ukuthi isigcwalisi siphelelwe yisikhathi futhi asivumelekile, uma sonakalisiwe, kufanele sishintshwe ngesikhathi.
(4) Ngemuva kokuthi i-valve isilungisiwe futhi ihlanganiswe, ukuhlolwa kokusebenza kokuvala kufanele kwenziwe.
2. Umsebenzi wokulungisa lapho i-valve igcotshwa
Ukugcinwa kochwepheshe kwe-i-valvengaphambi nangemva kwe-welding kanye nokukhiqiza kudlala indima ebalulekile enkonzweni ye-valve ekukhiqizeni nasekusebenzeni, futhi ukulungiswa okulungile nokuhlelekile nokuphumelelayo kuzovikela i-valve, yenze i-valve isebenze ngokujwayelekile futhi yandise impilo yesevisi ye-valve. Ukugcinwa kwe-valve kungase kubonakale kulula, kodwa akunjalo. Kuvame ukushaywa indiva izici zomsebenzi.
1. Uma i-valve igcotshwa, inkinga yokujova amafutha ngokuvamile ayinakwa. Ngemva kokuba isibhamu somjovo wamafutha sesikhulisiwe, opharetha ukhetha ivalvu nendlela yokuxhuma umjovo wamafutha ukuze enze umsebenzi womjovo wamafutha. Kunezimo ezimbili: ngakolunye uhlangothi, inani lomjovo wamafutha lincane, umjovo wamafutha awanele, futhi indawo yokuvala uphawu igqokwa ngokushesha ngenxa yokuntuleka kokugcoba. Ngakolunye uhlangothi, umjovo wamafutha omningi udala imfucuza. Lokhu kungenxa yokuthi asikho isibalo esinembile samandla okuvala ama-valve ahlukene ngokohlobo lohlobo lwe-valve. Umthamo wokuvala ungabalwa ngokuya ngobukhulu kanye nohlobo lwe-valve, bese inani elifanele lamafutha lingajovwa ngokufanelekile.
Okwesibili, lapho i-valve igcotshwa, inkinga yokucindezela ngokuvamile ayinakwa. Ngesikhathi sokusebenza komjovo wamafutha, ukucindezela komjovo wamafutha kushintsha njalo eziqongweni nasezigodini. Ingcindezi iphansi kakhulu, ukuvuza kophawu noma ingcindezi yokwehluleka iphezulu kakhulu, imbobo yokujova igrisi ivinjiwe, igrisi esitywinweni iqinisiwe, noma indandatho yokuvala ikhiywe ngebhola le-valve nepuleti levalvu. Imvamisa, lapho ingcindezi yokujova igrisi iphansi kakhulu, amafutha ajovwe ageleza adlulele ngaphansi kwembobo yevalvu, evame ukwenzeka kumavalvu esango amancane. Uma umfutho womjovo wamafutha uphezulu kakhulu, ngakolunye uhlangothi, hlola umlomo womjovo wamafutha, bese uwushintsha uma imbobo yamafutha ivinjiwe; Ngakolunye uhlangothi, ukuqina kwamafutha, lapho isisombululo sokuhlanza sisetshenziselwa ukuthambisa ngokuphindaphindiwe amafutha okufaka uphawu ahlulekile futhi esikhundleni salo namafutha amasha. Ukwengeza, uhlobo lokuvala kanye nezinto zokubeka uphawu nazo zithinta ukucindezela kwamafutha, amafomu okuvala ahlukene anokucindezela okuhlukile kwamafutha, ngokuvamile, ukucindezela kwe-grease seal okuqinile kuphakeme kunophawu oluthambile.
Ukwenza lo msebenzi ongenhla kukholakala ukuthi kuwusizo kakhulu ekwandiseni impilo yesevisi yei-valve, futhi ngesikhathi esifanayo, kunganciphisa nezinkinga eziningi ezingadingekile.
