Amavalvu, njengeminye imikhiqizo yemishini, nawo adinga ukulungiswa.Uma lo msebenzi wenziwe kahle, unganweba impilo yesevisi ye-valve.Okulandelayo kuzokwethula ukugcinwa kwe-valve.
1. Ukugcinwa nokugcinwa kwe-valve
Inhloso yokugcina nokugcinwa akukhona ukulimaza i-valve endaweni yokugcina noma ukunciphisa ikhwalithi.Eqinisweni, ukugcinwa okungalungile kungenye yezizathu ezibalulekile zokulimala kwe-valve.
Isitoreji se-valve, kufanele sihleleke kahle, ama-valve amancane eshalofini, ama-valve amakhulu angahlelwa kahle endaweni yokugcina impahla, hhayi inqwaba engahlelekile, ungavumeli indawo yokuxhumana ye-flange ithintane nomhlabathi.Lokhu akukona nje ngenxa yezizathu zobuhle, kodwa ikakhulukazi ukuvikela i-valve ekuqhekekeni.
Ngenxa yokugcinwa nokuphathwa ngendlela engafanele, isondo lesandla eliphukile, isiqu se-valve sigwegwile, isondo lesandla kanye nesiqu se-valve ukulahlekelwa okuxekethile okuxekethile, njll., lokhu kulahlekelwa okungadingekile kufanele kugwenywe.
Kuma-valve angasetshenziswa esikhathini esifushane, izigcwalisi ze-asbestos kufanele zisuswe ukuze kugwenywe ukugqwala kwe-electrochemical kanye nokulimala kwesiqu se-valve.
Ama-valve asanda kungena endaweni yokugcina impahla kufanele ahlolwe.Isibonelo, amanzi emvula noma ukungcola okungena ngesikhathi sokuthutha kufanele kusulwe futhi kugcinwe.
I-inlet ne-outlet ye-valve kufanele ivalwe ngephepha le-wax noma ishidi lepulasitiki ukuvimbela ukungcola ukuthi kungangeni.
Indawo yokucubungula i-valve engagqwala emkhathini kufanele igcotshwe ngamafutha e-antirust ukuyivikela.
Amavalvu abekwe ngaphandle, kumele ambozwe ngezinto ezingangenwa yimvula futhi zingangenwa uthuli njengelinoleum noma iseyili.Indawo lapho kugcinwa khona ama-valve kufanele igcinwe ihlanzekile futhi yomile.

2. Ukusebenza nokugcinwa kwe-valve
Inhloso yokusebenza nokugcinwa kwe-valve ukwandisa isikhathi sokuphila kwe-valve nokuqinisekisa ukuvulwa nokuvala okuthembekile.
Intambo ye-valve stem, evamise ukungqubuzana kwe-valve stem nati, izogcotshwa ngamafutha amancane aphuzi owomile, i-molybdenum disulfide noma i-graphite powder, ukuthambisa.
Ku-valve engavamile ukuvulwa futhi ivaliwe, kuyadingeka futhi ukuzungeza isondo lesandla njalo futhi wengeze i-lubricant kuntambo ye-stem ukuvimbela ukuluma.
Kuma-valve angaphandle, umkhono ovikelayo kufanele wengezwe esiqwini se-valve ukuvimbela imvula, iqhwa nokugqwala kothuli.
Uma i-valve ibekwe ngomshini, kuyadingeka ukwengeza uwoyela wokugcoba ku-gearbox ngesikhathi.
Gcina i-valve ihlanzekile njalo.
Hlola njalo futhi ugcine ubuqotho bezinye izingxenye ze-valve.Uma i-nati engashintshi ye-handwheel iwa, kufanele ifaniswe, ngaphandle kwalokho izogaya izinhlangothi ezine zengxenye engenhla ye-valve stem, kancane kancane ilahlekelwe ukwethembeka kokufanisa, futhi ihluleke ngisho nokuqala.
Unganciki ku-valve ukusekela ezinye izinto ezinzima, ungami ku-valve.
Isiqu se-valve, ikakhulukazi ingxenye yentambo, kufanele yesulwe kaningi, futhi i-lubricant engcoliswe uthuli kufanele ishintshwe entsha, ngoba uthuli luqukethe imfucumfucu eqinile, okulula ukuyigqoka intambo kanye nengaphezulu isiqu se-valve, esithinta impilo yesevisi.

3. Ukugcinwa kwe-valve yokupakisha
Ukupakisha kuwuphawu oluyisihluthulelo oluhlobene ngokuqondile nokuthi ukuvuza kwenzeka yini lapho i-valve ivulwa futhi ivaliwe, uma ukwehluleka ukupakisha, okuholela ekuvuzeni, i-valve ilingana nokwehluleka, ikakhulukazi i-valve yepayipi ye-urea, ngoba izinga lokushisa layo liphakeme kakhulu, ukugqwala kuphakeme kakhulu, ukupakisha kulula ukuguga.Ukuqinisa isondlo kungandisa impilo yokupakisha.
Lapho i-valve ishiya imboni, ukuze kuqinisekiswe ukunwebeka kokupakisha, ngokuvamile ingaphansi kokuhlolwa kwengcindezi emile ngaphandle kokuvuza.Ngemuva kokuthi i-valve ilayishwe epayipini, ngenxa yokushisa nezinye izici, kungase kube nokuphuma kwamanzi, ngakho-ke kuyadingeka ukuqinisa i-nati ezinhlangothini zombili zegland yokupakisha ngesikhathi, inqobo nje uma ingavuzi, bese kuthi-ke. i-seepage futhi, ungaqinisi kanye, ukuze ugweme ukulahlekelwa ukunwebeka kokupakisha kanye nokulahlekelwa kokusebenza kokuvala.
Okunye ukupakisha kwe-valve kufakwe i-molybdenum disulfide lubrication paste, lapho isetshenziselwa izinyanga ezimbalwa, kufanele ifike ngesikhathi ukuze ungeze amafutha okugcoba ahambisanayo, lapho kutholakala ukuthi isigcwalisi sidinga ukungezwa, kufanele sikhuphuke ngesikhathi esifanele ukupakisha okuhambisanayo, ukuze kuqinisekiswe ukuthi ukusebenza kwayo kokubekwa uphawu.

4. Ukugcinwa kwezingxenye zokudluliswa kwe-valve
I-Valve ngesikhathi sokushintsha, uwoyela wokuqala wokugcoba uzoqhubeka nokulahlekelwa, kuhambisana nendima yamazinga okushisa, ukugqwala nezinye izici, kuzokwenza uwoyela wokugcoba uhlale endaweni eyomile.Ngakho-ke, izingxenye zokudlulisela ze-valve kufanele zihlolwe njalo, kutholakale ukuthi ukungabi khona kwamafutha kufanele kugcwaliswe ngesikhathi, ukuze kuvinjwe ukungabi khona kwe-lubricant nokwandisa ukugqoka, okuholela ekudluliseni okungenakuguquguquka nokunye ukwehluleka.

Ukugcinwa kwe-valve kufanele kuphathwe ngesimo sengqondo sesayensi, ukuze kwenziwe ukugcinwa kwe-valve kusebenze ukufeza imiphumela oyifunayo kanye nezinhloso zokufaka isicelo.Ukuze wenze ukusebenza okuvamile kokukhiqiza, ukunciphisa ukupaka nokwandisa izinzuzo zezomnotho, ku-valve, kufanele senze lawa maphuzu amathathu:
Ukukhetha kahle ama-valve kuyisisekelo.
Ukusetshenziswa kahle kwe-valve kuyisihluthulelo.
Ukunakekela okulungile kuyisiqinisekiso.
