Umehluko Phakathi Kwamavalvu Asebenza Ngaqondile Nawe-Pilot
2024-03-14Izimiso zamavalvu asebenza ngomshayeli namavalvu asebenza ngokuqondile
Ama-valve asebenza ngomshayelifuthi ama-valve asebenza ngokuqondile ama-valve avamile okulawula ukucindezela. Zihlukile endleleni i-spool yokulawula ehamba ngayo.
Ama-valve asebenza ngomshayeli ngokuvamile anezela imbobo yokushayela ezungeze umnyombo we-valve. Lapho i-valve core yokulawula isuswa, ukusatshalaliswa kwengcindezi yembobo yokushayela kuzoshintshwa. Ngalesi sikhathi, i-medium ingena noma ikhishwe ekamelweni lokulawula ngembobo yokushayela, ngaleyo ndlela iguqule ukucindezela kwekamelo lokulawula. Ukulawula ukuvulwa nokuvalwa kwe-valve.
Ama-valve asebenza ngokuqondile alungisa ngokuqondile ukugeleza kwe-medium ngokulawula indawo ye-valve core. Lapho i-spool yokulawula ihamba, ukuvulwa kwe-valve kuzoshintsha ngokufanele.
Izinzuzo kanye nokungalungi kwama-valve aqhutshwa umshayeli kanye nama-valve asebenza ngokuqondile
1. Ivalvu esebenza ngomshayeli
Ama-valve asebenza ngomshayeli asebenzisa imbobo yokuhlola ukwenza i-valve ibe bucayi futhi isheshe ukushintsha phakathi nendawo. Ngakho-ke, ama-valve aqhutshwa umshayeli afaneleka ezimweni lapho ukusabela okusheshayo ekushintsheni kwemidiya kuyadingeka. Ngaphezu kwalokho, i-valve eqhutshwa umshayeli inokunemba okuphezulu kokulawula futhi inganciphisa ngempumelelo i-amplitude yokuguquguquka kwengcindezi ephakathi.
Kodwa-ke, ngenxa yokuba khona kwembobo yokushayela, i-valve yomshayeli isebenza ngokungazinzile lapho umehluko wengcindezi uphansi futhi ujwayele ukukhiya. Ngaphezu kwalokho, ngaphansi kokushisa okuphezulu kanye nemidiya ye-viscosity ephezulu, umgodi wokushayela uvinjelwe kalula, othinta ukusebenza okuvamile kwe-valve.
2. Ivalvu ebambelayo eqondile
Ama-valve asebenza ngokuqondile awanazo izimbobo zokushayela, ngakho-ke akukho mkhuba wokukhiya wamavalvu asebenza ngomshayeli. Ngaphezu kwalokho, ama-valve asebenza ngokuqondile azinzile ngaphansi kwe-high-temperature ne-high-viscosity media.
Kodwa-ke, uma kuqhathaniswa nama-valve asebenza ngomshayeli, ama-valve asebenza ngokuqondile anejubane eliphansi lokuphendula kanye nokunemba okuphansi kokulawula. Ngaphezu kwalokho, ama-valve asebenza ngokuqondile azokhiqiza inani elithile lokudlidliza kwe-valve core kanye nomsindo ngesikhathi sokusebenza, okuzothinta umphumela wokusetshenziswa.
Sengiphetha, womabili ama-valve asebenza ngomshayeli kanye nama-valve asebenza ngokuqondile anezinzuzo ezihlukile kanye nokubi. Ukukhetha phakathi kwalezi zinhlobo ezimbili zamavalvu kuncike ezidingweni ezithile zohlelo lokusebenza, okuhlanganisa isidingo sokuphendula ngokushesha, ukunemba kokulawula, ukuzinza ngaphansi kwezimo zemidiya ezihlukene, nokubekezelela ukudlidliza nomsindo. Ngokuqonda izimiso nezici zohlobo ngalunye lwe-valve, onjiniyela nabaklami besistimu bangenza izinqumo ezinolwazi ukuze baqinisekise ukusebenza kahle ezindaweni ezihlukahlukene zezimboni nezentengiso.
