Ivalvu iyisisetshenziswa esiwumshini esilawula ukugeleza, ukugeleza, ukugeleza, ukucindezela, izinga lokushisa, njll. koketshezi olugelezayo, futhi i-valve iyingxenye eyisisekelo ohlelweni lwamapayipi. Ukufakwa kwamavalvu kuyafana ngokobuchwepheshe namaphampu futhi kuvame ukuxoxwa njengesigaba esihlukile. Ngakho yiziphi izinhlobo zama-valve? Ake sithole ndawonye.
Njengamanje, izindlela ezivame ukusetshenziswa kakhulu zokuhlukanisa ama-valve emazweni omhlaba nasekhaya yilezi ezilandelayo:
1. Ngokwezici zesakhiwo, ngokuya ngesiqondiso lapho ilungu elivalayo lihamba khona lihlobene nesihlalo se-valve, lingahlukaniswa libe:
1. Umumo osikiwe: ingxenye yokuvala ihamba phakathi nendawo yesihlalo sevalvu.
2. Isimo sesango: ilungu elivalayo lihamba phakathi nendawo yesihlalo esime mpo.
3. Iqhude nebhola: Ilungu elivalayo i-plunger noma ibhola elizungeza umugqa ophakathi nendawo.
4. Swing shape; ilungu elivalayo lizungeza i-eksisi ngaphandle kwesihlalo sevalvu.
5. Isimo sediski: idiski yelungu elivalayo izungeza i-eksisi esesihlalweni sevalvu.
6. Umumo wevalvu yesilayidi: ilungu elivalayo lislayida liqonde ngqo esiteshini.
2. Ngokwendlela yokushayela, ingahlukaniswa ngezindlela ezihlukene zokushayela:
1. Ugesi: oshayelwa yinjini noma ezinye izinto zikagesi.
2. Amandla e-hydraulic: aqhutshwa (amanzi, amafutha).
3. I-Pneumatic: sebenzisa umoya ocindezelwe ukushayela i-valve ukuze ivule futhi ivale.
4. Imanuwali: Ngosizo lwamasondo ezandla, izibambo, ama-lever noma ama-sprocket, njll., iqhutshwa ngabasebenzi. Uma idlulisa i-torque enkulu, ifakelwe izinto zokunciphisa ezifana namagiya wezikelemu namagiya.
3. Ngokwenhloso, ngokuya ngokusetshenziswa okuhlukile kwe-valve, ingahlukaniswa ibe:
1. Ngokuphuka: okusetshenziselwa ukuxhuma noma ukusika i- medium yepayipi, njenge-valve yeglobhu, i-valve yesango, i-valve yebhola, i-butterfly valve, njll.
2. Ngokungabuyi: isetshenziselwa ukuvimbela ukubuyela emuva kokuphakathi, njenge-valve yokuhlola.
3. Ukulungiswa: kusetshenziselwa ukulungisa ukucindezela nokugeleza kwe-medium, njengama-valve okulawula kanye nama-valve okunciphisa ukucindezela.
4. Ukuze kusatshalaliswe: kusetshenziselwa ukuguqula indlela yokugeleza kwe-medium nokusabalalisa okuphakathi, njengamaqhude anezindlela ezintathu, ama-valve okusabalalisa, ama-slide valve, njll.
5. Ivalvu yokuphepha: Uma ingcindezi yendawo ephakathi idlula inani elishiwo, isetshenziselwa ukukhipha okuphakathi okweqile ukuze kuqinisekiswe ukuphepha kwesistimu yamapayipi nezinto zokusebenza, njenge-valve yokuphepha kanye ne-valve yezimo eziphuthumayo.
6. Ezinye izinjongo ezikhethekile: njengezicupho ze-steam, ama-valve okukhipha umoya, ama-valve endle, njll.
