Isingeniso kusimiso se-check valve

I-Check valve, eyaziwa nangokuthi i-check valve, i-check valve, isimiso sayo sokusebenza sisekelwe kakhulu ekuvulekeni nasekuvalekeni okuzenzakalelayo kwediski ye-valve ukulawula ukugeleza kwendlela eyodwa kwe-medium nokuvimbela ukugeleza emuva. Okulandelayo isingeniso esiningiliziwe sesimiso sokusebenza se-check valve:

Okokuqala, isimiso esiyisisekelo sokusebenza

Isimiso sokusebenza sevalvu yokuhlola singafingqwa kanje: lapho i-medium (njengoketshezi, igesi, njll.) igeleza ngendlela enqunyiwe, idiski yevalvu ivulwa ngokuzenzakalelayo yingcindezi ye-medium, okuvumela i-medium ukuthi idlule; Lapho i-medium izama ukubuyisela emuva ukugeleza, idiski yevalvu ivala ngokuzenzakalelayo ngaphansi kwesenzo sengcindezi ephakathi kanye namandla ayo adonsela phansi, ivimbela i-medium ukuthi igeleze emuva.

Okwesibili, isimiso esithile sokusebenza

Ngokwesakhiwo sevalvu yokuhlola, isimiso sayo sokusebenza sihlukile kancane, kodwa isimiso esiyisisekelo siyafana. Okulandelayo kusebenzisa amavalvu okuhlola okujikijelayo kanye namavalvu okuhlola okuphakamisa njengezibonelo:

1. I-valve yokuhlola ukujika

Izici zesakhiwo: Idiski yevalvu yokuhlola i-swing ixhunywe nomzimba wevalvu ngendlela yehinge, futhi ingajikeleziswa ngokukhululekile. Idiski ivame ukuba yidiski futhi ijikeleza iphini phakathi nesihlalo.

Isimiso sokusebenza: Uma i-medium igeleza phambili, i-valve disc icindezelwa yi-medium, bese ijikeleza umgodi wephini ukuze ivumele i-medium ukuthi idlule; Uma i-medium igeleza emuva, i-valve disc ibhekana nesenzo esiphindwe kabili somfutho ophakathi kanye namandla ayo adonsela phansi, bese ijikeleza umgodi wephini ukuze ivimbele i-medium ukuthi igeleze emuva.

2. I-valve yokuhlola ukuphakamisa

Izici zesakhiwo: I-flap ye-lift check valve ihamba phezulu naphansi eduze kwe-axis. I-disc ivame ukutholakala endaweni yokuvala isihlalo yomzimba we-valve futhi ingaphakanyiswa futhi yehliswe ngokukhululeka.

Isimiso sokusebenza: Uma i-medium igeleza phambili, i-valve disc iphakanyiswa yingcindezi ye-medium, bese isiteshi sivulwa ukuze kuvunyelwe i-medium ukuthi idlule; Uma i-medium igeleza emuva, i-valve disc incishiswa yisenzo esiphindwe kabili sengcindezi ephakathi kanye namandla ayo adonsela phansi, bese isiteshi sivalwa ukuvimbela i-medium ukuthi igeleze emuva.

Okwesithathu, izici zomsebenzi

Ama-valve okuhlola anezici zokusebenza ezilandelayo:

1. Ukuzenzakalela: I-valve yokuhlola iyi-valve ezenzakalelayo engadingi ukulawulwa kwangaphandle noma ukungenelela ukuze kufezwe ukugeleza kwendlela eyodwa kwe-medium nokuvimbela ukugeleza emuva.

2. Ukuvala: I-valve yokuhlola isebenza kahle ekuvaleni phakathi kwediski nesihlalo ukuqinisekisa ukuthi i-medium ingavinjelwa ngempumelelo lapho ukugeleza okuphambene kugeleza.

3. Ukuthembeka: I-valve yokuhlola inesakhiwo esilula kanye nokusebenza okuthembekile, futhi ingagcina ukusebenza okuzinzile ngaphansi kwezimo zokusebenza ezahlukahlukene.

Okwesine, insimu yesicelo

Ama-valve okuhlola asetshenziswa kabanzi ezinhlelweni ezahlukahlukene zoketshezi, njengezinhlelo zokuphakelwa kwamanzi kanye nokukhipha amanzi, izinhlelo ze-HVAC, izinqubo zokukhiqiza zezimboni, njll., ukuvimbela ukugeleza kwemidiya emuva nokuvikela imishini nezinhlelo ekulimaleni.

Ngamafuphi, i-check valve ilawula ukugeleza kwendlela eyodwa kwe-medium futhi ivimbela ukubuyela emuva ngokuvula nokuvala okuzenzakalelayo kwe-valve disc. Isimiso sayo sokusebenza silula futhi sithembekile, futhi sidlala indima ebalulekile ezinhlelweni ezahlukene zoketshezi.
