Hlola umthetho wokusebenza kwevalvu, ukuhlukaniswa nokufaka

Indlela i-valve yokuhlola esebenza ngayo

Iivalvu yokuhlola isetjenziswa erherhweni lamapayipi, begodu umsebenzi wayo omkhulu kukhandela ukubuyela emuva kwe-medium, ukujikeleza emuva kwepompo kanye ne-motor yayo etjhayelako, nokukhutjhwa kwe-medium esitjeni.

Hlola amavalvu ingasetjenziswa godu emigqeni ephakela amasistimu asizako lapho umfutho ungakhuphuka ngaphezu komfutho omkhulu wesistimu. Amavalvu wokuhlola angasetjenziswa emaphayiphini weendaba ezihlukahlukeneko ngokuya ngezinto ezihlukahlukeneko.

Ivalvu yokuhlola ifakwa epayipini begodu iba ngenye yeengcenye ze-fluid yepayipi epheleleko. Ikambiso yokuvula nokuvala idiski yevalvu ithintwa bujamo bokugeleza kwesikhatjhana kwesistimu lapho itholakala khona; ngokulandelana, ubujamo bokuvala kwediski yevalvu bunomthelela ebujameni bokugeleza kwe-fluid.

Hlola ukuhlukaniswa kwevalvu

1. Ivalvu yokuhlola yokujinga

Idiski yevalvu yokuhlola i-swing inesimo sediski begodu ijikeleza ishafti yesiteshi sesihlalo sevalvu. Ngombana isiteshi esise-valve sihlelwe kuhle, ukujamelana nokugeleza kuncani kunaleyo ye-lift check valve. Ilungele amazinga aphasi wokugeleza nokutjhuguluka okungakavami kokugeleza. Kodwana, ayikulungele ukugeleza okushayako, begodu ukusebenza kwayo kokuvala akusikuhle njengomhlobo wokuphakamisa.

I-swing check valve ihlukaniswe yaba mihlobo emithathu: umhlobo we-single-lobe, double-lobe kanye no-multi-lobe. Amafomu amathathu la ahlukaniswe ngokuya ngobubanzi bevalvu.

2. Phakamisa ivalvu yokuhlola

I-valve yokuhlola lapho idiski ye-valve itjhelela emgqeni ophakathi oqondileko womzimba we-valve. Ivalvu yokuhlola ukuphakamisa ingafakwa kwaphela ephayiphini evundlileko, begodu ibholo ingasetjenziselwa idiski yevalvu kuvalvu yokuhlola encani enomfutho omkhulu. Ijamo lomzimba wevalvu we-lift check valve liyafana nele-globe valve (lingasetjenziswa ngokufana ne-globe valve), ngalokho-ke i-fluid resistance coefficient yayo yikulu. Isakhiwo sayo sifana ne-globe valve, begodu umzimba we-valve nediski kuyafana ne-globe valve.

3. Ivalvu yokuhlola ivithamini

Ivalvu yokuhlola lapho idiski ijikeleza khona ipini esihlalweni. I-disc check valve inesakhiwo esilula begodu ingafakwa kwaphela ephayiphini evundlileko, begodu ukusebenza kokuvala akukalungi.

4. Ivalvu yokuhlola iphayiphi

Ivalvu lapho idiski itjhelela khona emgqeni ophakathi womzimba wevalvu. Ivalvu yokuhlola iphayiphi yivalvu etja. Incani ngobukhulu, ilula ngobunzima begodu ilungele ithekhnoloji yokucubungula. Ngenye yeendlela zokuthuthukisa i-valve yokuhlola. Kodwana, izinga lokujamelana noketshezi likhulu kancani kunaleyo ye-swing check valve.

5. Ivalvu yokuhlola ukugandeleleka

Umhlobo lo wevalvu usetjenziswa njengevalvu yokuphakela amanzi webhoyila kanye nevalvu yokusika umtjhiso, inomsebenzi ohlanganisiweko wevalvu yokuhlola ukuphakamisa kanye nevalvu ye-globe nofana ivalvu ye-angle.

Ukungezelela, kunamavalvu wokuhlola angakafaneli ukufakwa kwepompo, njengevalvu yeenyawo, umhlobo we-spring, umhlobo we-Y, njll.
