I-valve yesondlo yansuku zonke kanye ne-valve yokulungisa ivuza izindlela ezinhlanu zobuchwepheshe ukubhekana nazo

Ama-valve awasetshenziswa kuphela ezimbonini ezihlukahlukene, kodwa nasezindaweni ezihlukene. Amanye ama-valve ezindaweni zokusebenza ezingezinhle ajwayele ukuba nezinkinga. Ngenxa yokuthi ama-valve ayimishini ebalulekile, ikakhulukazi kwamanye ama-valve amakhulu, uma kunenkinga yokukhanda noma ukushintshwa kuyinkinga impela. Ngakho ukwenza umsebenzi omuhle wokunakekela nokunakekela nsuku zonke kubaluleke kakhulu. Ake sibheke ulwazi oluncane mayelana nokugcinwa kwama-valve.
Ama-valve awasetshenziswa ezimbonini ezihlukahlukene kuphela, kodwa nasezindaweni ezihlukene zokusebenzisa. Amanye ama-valve ezindaweni zokusebenza ezingezinhle ajwayele ukuba nezinkinga. Ngenxa yokuthi ama-valve ayimishini ebalulekile, ikakhulukazi kwamanye ama-valve amakhulu, uma kunenkinga yokukhanda noma ukushintshwa kuyinkinga impela. Ngakho ukwenza umsebenzi omuhle wokunakekela nokunakekela nsuku zonke kubaluleke kakhulu. Ake sibheke ulwazi oluncane mayelana nokugcinwa kwama-valve.
1. Ukugcinwa kanye nokuhlolwa kwansuku zonke kwama-valve
I-1, i-valve kufanele igcinwe ekamelweni elomile nelingenawo umoya, zombili iziphetho zendlela kufanele zivalwe.
I-2, isitoreji sesikhathi eside se-valve kufanele sihlolwe njalo, ukungcola, namafutha okugqwala agcotshwe endaweni yokucubungula.
3. Ngemuva kokufakwa, ukuhlolwa okuvamile kufanele kwenziwe. Izinto zokuhlola eziyinhloko yilezi:
(1) Ukugqokwa kokuvala indawo.
(2) ukugqokwa kwentambo ye-trapezoidal yesiqu ne-stem nut.
(3) ukuthi ukupakisha kuphelelwe yisikhathi futhi akuvumelekile, uma konakele, kufanele kushintshwe ngesikhathi.
(4) Ngemuva kokulungiswa nokuhlanganisa ama-valve, ukuhlolwa kokusebenza kokuvala uphawu kufanele kwenziwe.
Okwesibili, umsebenzi wokulungisa i-valve grease
Ukugcinwa kochwepheshe kwe-valve ngaphambi kokushisela nangemva kokukhiqiza kudlala indima ebalulekile ekukhiqizeni nasekusebenzeni kwe-valve. Ukugcinwa okulungile nokuhlelekile futhi okuphumelelayo 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.
I-valve grease, ngokuvamile ayinaki inkinga yesamba samafutha. Ngemuva kokugcwalisa amafutha, opharetha ukhetha ukuxhumana phakathi kwe-valve nokugcwalisa amafutha, bese egcwalisa ukugcwaliswa kwamafutha. Kunezimo ezimbili: ngakolunye uhlangothi, inani lamafutha lingaphansi kokwanele, futhi indawo yokuvala uphawu igqokwa ngokushesha ngenxa yokuntuleka kokugcoba. Ngakolunye uhlangothi, umjovo wamafutha amaningi udala imfucuza. Akukho ukubala okunembile komthamo wophawu lwe-valve ngokusho kwesigaba sohlobo lwe-valve. Ungakwazi ukubala umthamo wokuvala ngosayizi wevalvu kanye nesigaba, bese ujova inani elifanelekile lamafutha.
Okwesibili, amafutha e-valve, ngokuvamile angayinaki inkinga yokucindezela. Ngesikhathi sokusebenza komjovo we-lipid, ingcindezi yomjovo we-lipid inoshintsho olujwayelekile lwe-peak-valley. 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 uma ingcindezi yokujova igrisi iphansi kakhulu, igrisi ejovwe igelezela ngaphansi kwegumbi levalvu, ngokuvamile eyenzeka kumavalvu esango amancane. Ngenkathi ukucindezela komjovo wamafutha kuphezulu kakhulu, ngakolunye uhlangothi, hlola i-nozzle yamafutha, uma imbobo yamafutha ivinjiwe, yishintshe; Ngakolunye uhlangothi, ukuqina kwe-lipid, uketshezi lokuhlanza kufanele kusetshenziselwe ukuthambisa ngokuphindaphindiwe amafutha ophawu ohlulekile, kanye nokujova ukushintshwa kwamafutha amasha. Ngaphezu kwalokho, uhlobo lwe-seal kanye nempahla yophawu, nayo ithinta ingcindezi yomjovo, amafomu ophawu ahlukene anengcindezi ehlukile yomjovo, ngokuvamile, ingcindezi yomjovo wophawu oluqinile iphakeme kunophawu oluthambile.
Yenza umsebenzi ongenhla, ngikholelwa ukuthi ukwelula impilo yesevisi ye-valve kuyasiza kakhulu, kodwa futhi kunganciphisa izinkinga eziningi ezingadingekile.
Izindlela ezinhlanu zobuchwepheshe zokubhekana nokuvuza kwe-valve
Ukuvuza komzimba we-valve kanye nekhava ye-valve:
Isizathu:

I-4, umhlangano we-gasket kufanele uhlangane nendawo, amandla afanayo, i-gasket ayivunyelwe ukugoqa futhi isebenzise i-gasket kabili;
5, ukugqwala kokubekwa uphawu okumile, ukucutshungulwa komonakalo, ikhwalithi yokucubungula ayiphezulu, kufanele ilungiswe, ukugaya, ukuhlolwa kombala, ukwenza indawo yokubeka uphawu emile ihlangabezane nezidingo ezifanele;
6. Uma ufaka i-gasket, ukunakwa kufanele kukhokhwe ekuhlanzeni, ukubeka uphawu kufanele kube i-parafini ecacile, futhi i-gasket akufanele iwele phansi.
Okwesine, ukuvuza koxhumano lwendandatho yokuvala uphawu
Isizathu:
1, ukugoqa indandatho yokuvala akuqinile
2, indandatho yokuvala kanye nokushisela umzimba, ikhwalithi yokuvela impofu;
3, intambo yokuxhuma indandatho yokuvala, isikulufu, indandatho yokucindezela ikhululekile;
4. Indandatho yokuvala ixhunyiwe futhi igqwalile.
Izindlela zokunakekela:
1. Ukuvuza endaweni yokuginqika evalekile kufanele kulungiswe ngokujova ingcina bese iyagoqeka;
