Yini inhloso ye-valve yokuhlola?

Bheka i-valve, eyaziwa nangokuthiBheka i-valveNoma i-valve yendlela eyodwa, iyingxenye ebalulekile ezinhlelweni zokulawula uketshezi. Inhloso yayo eyisisekelo ukuvikela emuva okuphakathi nendawo, kuqinisekiswe ukugeleza kwamanzi okukodwa, ukuvikela imishini, futhi kugcinwe ukusebenza kohlelo oluzinzile.

Ezinhlelweni zamapayipi,Bheka ama-valvesFinyelela umsebenzi we-Anti Backflow ngokuvula okuzenzakalelayo nokuvalwa kwama-valve disc. Lapho indlela ephakathi iyogeleza iqhubekela phambili, ingcindezi icindezela i-valve disc ukuvula, ukuvumela uketshezi ukuthi ludlule kahle; Lapho nje umgwaqo ophakathi nendawo abuyele emuva, i-valve disc ngokushesha iseva ngaphansi kwesenzo esimbili sesisindo sayo nokucindezela emuva, ukusika indlela yangemuva. Isibonelo, emapayipi kawoyela kanye negesi, ama-valves ahlola angavimba ngempumelelo i-backflow yotshwala noma amagesi, agweme ubungozi bomonakalo noma ukuqhuma ohlelweni lwepayipi; Ekukhiqizeni amakhemikhali, kungavimba i-backflow yemidiya ewonambathi kanye nokuvikela imishini yokuguguleka kwamakhemikhali.

Bheka ama-valves anezinhlobonhlobo zezimo zohlelo lokusebenza, ezimboza zombili izinkambu zezimboni nezakhamuzi. Njenge-valve engezansi yedivaysi yokupompa, kungavimba amanzi ukuthi ageleze abuyele emuva futhi aqinisekise ukusebenza okuqhubekayo nokuzinzile kwepompo yamanzi; Uma isetshenziswa ngokuhlanganiswa ne-valve evaliwe, ingafinyelela ukuhlukaniswa okuphephile futhi ivikele ukungcoliswa kwe-medium. Ngaphezu kwalokho, hlola ama-valves nawo angasetshenziselwa uhlelo olusizayo olunikezela ngamapayipi. Lapho ingcindezi yesistimu ingadlula lelo hlelo oluphambili, lingavimbela ngokuzenzakalelayo ukufulathela okuphakathi futhi kuqinisekise ukuphepha kohlelo.

Ngokombono wokuhlukaniswa kwesakhiwo,Bheka ama-valvesFaka ikakhulukazi izinhlobo ezintathu: Uhlobo lokujikisa, uhlobo lokuphakamisa, nohlobo lwevemvane. I-Rotary Check valve ithembele ku-Valve disc ijikeleza ezungeze i-axis ukufezekisa ukuvula nokuvala, ilungele ukugeleza okuphansi noma uketshezi olunoshintsho oluncane; I-valve disc yokuhlola i-valve valve slides eduze kwe-centerline mpo yomzimba we-valve, okuholela ekubekeni kangcono ukubekwa uphawu kodwa ukumelana noketshezi; I-valve yokuhlola uvemvane inesakhiwo esilula, kepha ukusebenza kwalo kokubopha kubuthakathaka. Bheka ama-valves anezinhlaka ezahlukahlukene angakhethwa ngokuya ngezimpawu ze-medium, amapayipi, nezidingo zohlelo.

Ngokuya ukufakwa nokulungiswa, ukuqondiswa kwama-valves okuhlola kubalulekile, futhi kuyadingeka ukuqinisekisa ukuthi ukuqondiswa kokugeleza okuphakathi kuyahambisana nokuqondisa komcibisholo we-valve womzimba. Ngasikhathi sinye, kuyadingeka ukugwema ukusika noma ukuthutha e-valve efakiwe ukugwema ukulimaza umzimba we-valve nokubekwa uphawu. Ukubheka njalo isimo sokusebenza sama-valves okuhlola futhi kuthathe indawo ngokushesha noma ukulungisa izinto ezingajwayelekile kubalulekile ekuqinisekiseni ukusebenza kwesikhathi eside kohlelo.
