Ukuhlaziywa okujulile kokucaciswa nokusebenza kwamavalvu eglobhu e-flange ajwayelekile yaseShayina
Ezinhlelweni zamapayipi ezimboni, amavalvu embulunga adlala indima ebalulekile njengoba esebenza njengabalindisango abaqinile, alawula ukugeleza koketshezi. Phakathi kwezinhlobo eziningi zama-valve embulunga, i-valve yaseShayina ejwayelekile ye-flange igqama ngokuguquguquka kwayo okuhle kakhulu nokuthembeka. Namuhla, sizokwembula iveyili yayo engaqondakali futhi sihlole ukucaciswa kwayo nokusebenza ngokuningiliziwe.
Ivalvu yeglobhu ye-flange ejwayelekile yaseShayina, njengoba negama lisho, iyivalvu yembulunga eklanywe futhi yakhiqizwa ngokuvumelana namazinga kazwelonke, axhunywe ohlelweni lwamapayipi ngokuxhumeka kwe-flange. Lolu hlobo lwe-valve luklanywe kahle kakhulu futhi lungavulwa noma luvalwe ngokusebenza kwe-stem ephakamisayo ngaphandle kokushintsha isiqondiso sokugeleza koketshezi. Isakhiwo sawo ngokuvamile sihlanganisa izingxenye ezifana nomzimba we-valve, isembozo se-valve, i-valve disc, isiqu se-valve, iringi yokuvala, njll., ngayinye edlala indima ebalulekile.
Ngokuqondene nokucaciswa, ama-valve embulunga ye-flange ejwayelekile yaseShayina alandela izindinganiso ezifanele ezifana ne-GB/T12235, enobubanzi obubanzi obusuka kumamilimitha ambalwa kuya kumakhulu amaningana amamilimitha, angahlangabezana nezidingo zamapayipi anosayizi abahlukahlukene. Isibonelo, ivalvu yembulunga evamile ene-flanged ingase ibe nobubanzi obujwayelekile be-DN50, okusho ukuthi ingakwazi ukuxhumana ngaphandle komthungo nezinye izingxenye zamapayipi e-DN50. Ngaphezu kwalokho, ngokwezingcindezi ezihlukene zokusebenza, ama-valve embulunga nawo ahlukaniswe abe amazinga ahlukene okucindezela, njenge-1.6MPa, 2.5MPa, 4.0MPa, njll., ukuze ahlangabezane nezidingo zezimo zokusebenza ezahlukene.
Mayelana nokusebenza, izici zamavalvu embulunga ye-flange ejwayelekile yaseShayina zingafingqwa njengokuthi "ukunemba, ukuzinza, nokuqina". Okokuqala, ukunemba kubonakala ekhonweni lakho lokuhlinzeka ngokulawula ukugeleza okunembayo. Njengompheki onolwazi okwazi kahle ukushisa, ivalvu yomhlaba wonke ingalawula ngokunembile izinga lokugeleza nezinga lokugeleza koketshezi ngokulungisa ukuvuleka kwayo. Okwesibili, ukuzinza kubonakala ekusebenzeni kwayo okuhle kakhulu kokuvala. Kungakhathaliseki ukuthi kusendaweni enengcindezi ephezulu noma enengcindezi ephansi, ama-valve embulunga angagcina ukuvala kahle futhi avimbele ukuvuza, ngenxa yesakhiwo sokuvala esiklanywe ngokucophelela kanye nezinto zokuvala zekhwalithi ephezulu. Okokugcina, ukuqina kuqinisekiswa ngokukhethwa kwezinto ezimelana nokugqwala nezingagugi, kanye nezingxenye zomshini onembile, ukuze kuqinisekiswe ukwethembeka kwe-valve yembulunga ekusetshenzisweni kwesikhathi eside.
Ekusetshenzisweni okungokoqobo, izinzuzo zama-valve eglobhu e-flange e-Chinese zibonakala ikakhulukazi. Ukuthatha isitshalo samakhemikhali njengesibonelo, kudinga ukushintshwa njalo kokugeleza koketshezi phakathi nenqubo yokukhiqiza, engafinyelelwa kalula ngokusebenzisa i-valve yeglobhu yohlobo lwe-flange. Ngaphezu kwalokho, lapho ukugcinwa kwemishini noma ukushintshwa kuyadingeka, umsebenzi wokuvala we-valve yokuvala ungaqinisekisa ukusebenza kahle ngaphandle kokukhathazeka ngokuvuza kwamanzi.
Yiqiniso, ukukhetha i-valve yokuvala efanelekile nakho kudinga amakhono athile. Isibonelo, ezindaweni ezishisa kakhulu nezinomfutho ophezulu, kuyadingeka ukukhetha izinto eziphikisana nokushisa okuphezulu nokucindezela; Kumithombo yezindaba ebola kakhulu, kubalulekile ukukhetha izinto ezimelana nokugqwala. Konke lokhu kudinga ukucatshangelwa ngokucophelela okusekelwe ezimweni zangempela zokusebenza.
Kafushane, ama-valve eglobhu ama-flange ajwayelekile aseShayina aseyingxenye ebaluleke kakhulu yezinhlelo zamapayipi ezimboni ngenxa yokucaciswa kwawo okuhlukahlukene nokusebenza okuzinzile. Ukulawula kwayo okunembayo, ukubekwa uphawu okuhle kakhulu, nokuqina kuyenza isebenze kahle kakhulu ezindaweni ezihlukahlukene eziyinkimbinkimbi. Ukuqonda ukucaciswa kwayo nokusebenza kubaluleke kakhulu ekuqinisekiseni ukuphepha nokusebenza kahle kokukhiqizwa kwezimboni.
