I-valve yeglobe ehlanganisiwe yezimboni esezingeni eliphezulu Umkhiqizi waseChina
Iyini ivalvu yeglobe enemicu?
I-valve yembulunga ehlanganisiwekuwumklamo okhethekile wama-globe valve amancane.
Njengevalvu yomhlaba, inazo zonke izici zevalvu yomhlaba, ivula futhi ivale ngokushesha.
amavalvu. njengokujwayelekile, izingxenye zokuvula nokuvala ziyisango, ngesimo se-wedge, yingakho zibizwa ngokuthi i-wedge gate valve. Indlela yokunyakaza kwesango iqonde ngqo ohlangothini loketshezi. I-wedge gate valve ingavulwa ngokugcwele futhi ivalwe ngokuphelele futhi ayikwazi ukulungiswa futhi icindezelwe. I-gate valve yaklanywa ukuthi isetshenziswe ivuleke ngokuphelele noma ivalwe ngokuphelele.
kodwaI-valve yembulunga ehlanganisiweinezici zayo. Yenziwe ngensimbi yekhabhoni eyakhiwe, insimbi engagqwali, insimbi ye-alloy, enomzimba omncane, ifanele uketshezi olunomfutho ophezulu. Ibhonethi ingaboshwa, ishiselwe futhi ivalwe ngomfutho, ngokuya ngezimo zokusebenza.
Izici eziyinhloko ze-Threaded globe valve
Izici eziyinhloko ze-API602ivalvu yensimbi eyakhiwe
- 1) Isiqu esikhuphukayo ngentambo ephindwe kabili ye-acme enembile ukuze sisebenze ngokushesha.
- 2) Ijoyinti lomzimba kuya kwebhonethi elenzelwe ukufaka umthwalo ofanayo ku-gasket ukuqinisekisa ukuthi i-seal ayivuzi.
- 5) Isihlalo sangemuva esenzelwe ukunciphisa ingcindezi yangemuva ekupakisheni kwesiqu uma sihlezi ngokuphelele. Akukhuthazwa ukufaka esikhundleni se-stem packing ngaphansi kwengcindezi.
- 6) Ukupakisha isiqu kuklanyelwe ukulawula kahle ukuvuza kokukhishwa kwegesi okubalekayo emoyeni. Izinga lokuvuza kokukhishwa kwegesi eliphansi kakhulu liqinisekiswa ngokuphela okuhle endaweni yokuvala isiqu, ukucaca okuncishisiwe kwe-diametrical kanye nokulawula ukuqondeka kwesiqu.

Umbukiso Womkhiqizo: I-valve yembulunga ehlanganisiwe
Ukusetshenziswa kwe-Threaded globe valve
Lolu hlobo lweI-valve yembulunga ehlanganisiweisetshenziswa kabanzi emigwaqweni enoketshezi kanye nezinye izinto eziwuketshezi. Uphethiloli, uwoyela, Amakhemikhali, Amakhemikhali kaphethiloli, Amandla kanye Nezinsiza njll., ikakhulukazi ezimweni lapho ukusebenza kahle kokugeleza okuphezulu, ukuvala okuqinile kanye nesevisi ende kuyadingeka. Ukukhetha okubanzi kwezinto zokwakha igobolondo kanye nokuhlobisa kuhlanganisa lonke uhla lwezinhlelo zokusebenza, kusukela ohlotsheni lwensizakalo yansuku zonke engaboli kuya kwinsizakalo ebalulekile enemidiya enamandla kakhulu.
