Imanuwali Yekhwalithi Ephezulu Yezitolo Ezithengisa Izimpahla Ezithengiswayo Umkhiqizi webhola elintantayo wase-China umnikezeli wefekthri Umkhiqizi
Iyini i-valve yebhola elintantayo Mathupha?
Ivalvu yebhola elintantayo eyenziwe ngesandla isebenzisa ibhola elizungezayo nesiqu esihlinzeka ngokuvula/ukuvala ukugeleza.
II-valve yebhola elintantayo eyenziwe ngesandlasebenzisa ukucindezela komugqa wemvelo ukuze ucindezele futhi uvale ibhola esihlalweni esingezansi komfula.Ukucindezela komugqa kuvezwa endaweni enkulu - yonke ubuso obuphezulu bebhola, okuyindawo elingana nosayizi wepayipi langempela.
AI-valve yebhola elintantayo eyenziwe ngesandlaiyivalvu enebhola elintantayo (elingagxiliwe yi-trunnion) ngaphakathi komzimba we-valve, ikhukhuleka iye ohlangothini olungezansi lomfula bese isunduza ngokuqinile esihlalweni ngaphansi kwengcindezi ephakathi ukuze iqinisekise ukwethembeka kokuvala.I-valve yebhola elintantayo inesakhiwo esilula, ukusebenza kahle kokuvala kodwa impahla yesihlalo iyadingeka ukuze imelane nomsebenzi njengoba ingcindezi yokuvala ivalwe yindandatho yesihlalo.
Lapho i-valve ibekwe lapho ibhore iqondaniswe khona ngendlela efanayo nepayipi, isendaweni evulekile, futhi uketshezi lungadlula phansi komfula.I-NORTECHI-valve yebhola elintantayo eyenziwe ngesandla umkhiqizo omusha okhiqizwa ukuguqulwa kwe-valve evamile kanye nokwamukelwa kwezinga lamazwe ngamazwe lakamuva.
Izici eziyinhloko ze-NORTECHManual valve yebhola elintantayo ?
1. Idizayini Yezihlalo Ezikhethekile
samukela umklamo wesakhiwo sendandatho yophawu oluguquguqukayo yevalve yebhola elintantayo.Lapho ingcindezi ephakathi nendawo iphansi, indawo yokuxhumana yeringi yophawu nebhola incane.Izonciphisa ukungqubuzana kanye ne-torque yokusebenza futhi iqinisekise ukucinana ngesikhathi esifanayo.Lapho ukucindezela okuphakathi kukhushulwa, indawo yokuxhumana yendandatho yophawu nebhola iba nkulu kanye nokuguqulwa okunwebekayo kwendandatho yophawu, ukuze indandatho yophawu ibekezelele indawo ephakeme. umthelela ngaphandle kokulimala.
2. Idizayini Yesakhiwo Sokuvikela Umlilo
Esimweni somlilo ngesikhathi kusetshenziswa ivalvu, iringi yesihlalo eyenziwe nge-PTFE Noma ezinye izinto ezingezona ezensimbi zizobola noma zonakaliswe ngaphansi kwezinga lokushisa eliphezulu futhi kuzoholela ekuvuzeni okukhulu koketshezi, kuyingozi impela endaweni evuthayo noma eqhumayo. Indandatho yophawu olungashi ibekwe phakathi kwebhola nesihlalo ukuze emva kokushiswa kwesihlalo se-valve, okuphakathi kuzophusha ibhola ngokushesha libheke ezansi nendandatho yensimbi yophawu lwensimbi ukuze yakhe insimbi eyinsimbi esakhiweni sokuvala sensimbi esingalawula ngempumelelo ukuvuza kwe-valve. Ngaphezu kwalokho, i-gasket evala uphawu ye-flange ephakathi, engaqinisekisa ukuvala ngisho nangaphansi kwezinga lokushisa eliphezulu.

3. Isakhiwo esiphikisana ne-static
I-valve yebhola iklanywe ngesakhiwo esingaguquki kanye nedivaysi yokukhipha ugesi omile ukuze yakhe ishaneli emile phakathi kwebhola nomzimba ngesiqu ukuze ikhiphe ugesi ongashintshi okhiqizwa ukungqubuzana kwebhola nesihlalo, ukugwema umlilo noma ukuqhuma. okungase kubangelwe ukucwazimula okumile kanye nokuqinisekisa ukuphepha kwesistimu.

5. Ukuvimbela Ukukhiya kanye Nokusebenzisa Kabi
I-valve yebhola yamanuwali ingakhiywa ngelokhi endaweni evulekile egcwele noma evala ngokugcwele.Isiqephu sokuma esivulekile esingu-90° esivulekile nesivalekile esinembobo yokukhiya siklanyelwe ukugwema ukusebenzisa kabi ama-valve okubangelwa ama-opreator angagunyaziwe, futhi singavimbela ukuvuleka noma ukuvala kwamavalvu, noma ezinye izingozi ezibangelwa ukudlidliza kwepayipi noma izici ezingalindelekile.Isebenza kakhulu ikakhulukazi kuwoyela ovuthayo naqhumayo, amapayipi asebenza ngamakhemikhali nawezokwelapha noma amashubhu asensimini.Ingxenye esekhanda lesiqu efakwe nesibambo yamukela umklamo oyisicaba.Lapho ivalvu ivulwa khona, isibambo sihambisana nepayipi, futhi izinkomba zokuvala zevalvu ziqinisekisiwe ukuthi zilungile.

Imininingwane Yobuchwepheshe Yevalvu yebhola elintantayo Manuwali
Umbukiso Womkhiqizo: I-valve yebhola elintantayo eyenziwe ngesandla
Ukusetshenziswa kwe-Manual valve yebhola elintantayo
Ivalvu yethu yebhola elintantayo eyenziwe ngesandla ingasetshenziswa kabanzi ku-petrochemical, amakhemikhali, ensimbi, ekwenziweni kwephepha, kwezemithi kanye namapayipi okuthutha amabanga amade.etc, cishe yonke inkundla.
