Zingaki izinhlobo zama-valves ezihlolo owaziyo?

Zingaki izinhlobo zeBheka ama-valvesIngabe uyazi?

Bheka ama-valves, abizwa nangokuthi ama-valves wendlela eyodwa, asetshenziselwa ukuvikela i-backflow ephakathi futhi asetshenziswa kabanzi ezinhlelweni eziningi zezimboni nabezizwe, nezinhlobo ezahlukahlukene.

Ihlukaniswe ngesakhiwo, izinhlobo ezijwayelekile zifaka phakathi ukukhuphukaBheka ama-valves. I-valve disc yayo islayida e-vertical Centerline yomzimba we-valve futhi ngokuvamile ifakwe kumapayipi avundlile. Lolu hlobo lwe-valve ye-Checkve lunesakhiwo esilula nokusebenza kahle kokubekwa uphawu, kepha kunamandla amakhulu okumelana futhi kufanelekile ngentengo ephansi yokugeleza kanye nezicelo ezincane zobubanzi. Isibonelo, isetshenziswa kakhulu ekutholeni kwamanye amaphampu amancane amanzi ukuvikela amanzi ekugelezeni emuva ephampu.

Ama-Swing Check Valves nawo ajwayelekile. I-valve disc ijikeleza ezungeze i-eksisi yesiteshi sesihlalo se-valve futhi ingafakwa kumapayipi avundlile nawomile. Inokuphikiswa okuphansi koketshezi nokusebenza okuphansi okuphansi okuqhathaniswa nohlobo lokuphakamisa, kepha kungasetshenziswa ezimweni zokusebenza ngamawadi amakhulu namanani aphezulu okugeleza. Ama-Rotary Check Valves avame ukubonwa ezinhlelweni ezinkulu zamanzi kanye namapayipi e-petrochemical ukuqinisekisa ukuhamba kwendlela okukodwa.

Isakhiwo se-valve sokuhlola uvemvane sifana ne-valve yamabhabhathane, nge-valve disc ejikeleza ezungeze i-eksisi engaguquki. Kuncane ngosayizi, ukukhanya ngesisindo, kulula ukuyifaka, futhi kunomelana noketshezi oluphansi, kepha ukusebenza kwalo kokubopha kungokwesilinganiso. Isetshenziswa kakhulu ezinhlelweni zamapayipi ngezidingo eziphansi zokubekwa uphawu nendawo okulinganiselwe, okufana nemithi yokufaka umoya omncane kwezinye izakhiwo, ukuvikela ukubuyela emuva komoya.

Kukhona futhi i-valve yokuhlola i-valve ethembele ekuguqukeni kwe-diaphragm ukulawula ukuvulwa nokuvalwa kwe-valve. Lolu hlobo lwe-valve ye-Check valve lunesakhiwo esilula, ukubekwa uphawu okuthembekile, nezidingo eziphansi zokuhlanzeka kwe-medium. Ilungele imidiya ewuketshezi equkethe izinhlayiya eziqinile noma imicu. Kwelinye ipayipi yokwethuka kwamapayipi, i-diaphragmBheka ama-valveskungavikela ngempumelelo ukubuyela emuva kwendle futhi kuvikele ukusebenza okujwayelekile kwemishini.

Ngaphezu kwalokho, ngokuya ngezindlela ezahlukahlukene zokuxhumeka, ama-valves ahlole angahlukaniswa ngezixhumi ze-flange, ukuxhumana okufakwe, ukuxhumana, nezinye izinhlobo zokuhlangabezana nezidingo zokufaka zamapayipi. Izinhlobo ezahlukene zama-valves ezihlolo zinezimpawu zazo, futhi ezincelweni ezingokoqobo, zidinga ukukhethwa ngokusekelwe ezintweni ezifana nezakhiwo eziphakathi nendawo, ukucindezela kwengcindezelo, ukufakwa kwe-Checkve kudlala indima enhle ekuvikeleni i-backflow ephakathi.
