Izici zokugeleza ze-valve yokulawula ikakhulukazi zihlanganisa izici ezine zokugeleza: umugqa oqondile, amaphesenti alinganayo, ukuvulwa okusheshayo kanye ne-parabola.
Uma ifakwe kwinqubo yokulawula yangempela, ukucindezelwa okuhlukile kwe-valve kuzoshintsha ngokushintsha kwezinga lokugeleza.Okusho ukuthi, lapho izinga lokugeleza lincane, ukulahlekelwa kwengcindezi yengxenye yamapayipi kuncane, futhi ukucindezelwa okuhlukile kwe-valve kuzokwanda, futhi ukucindezelwa okuhlukile kwe-valve kuzokwehla lapho izinga lokugeleza likhulu.Lesi sici se-valve, esihlukile kusici esingokwemvelo, sibizwa ngokuthi isici sokugeleza esisebenzayo.
I-valve yangaphakathi yesici sokuqala esisheshayo inomumo wediski futhi isetshenziselwa ngokuyinhloko isenzo sokuvula/ sokuvala.
Izici zokulawula ukugeleza kwe-valve yokulawula i-spool surface shape valve zinqunywa izici zokugeleza kwe-valve kanye nenhlanganisela yamapayipi enqubo, amaphampu, njll., futhi zikhethwa kuthebula elingezansi ngokuya ngenani lokulahleka komfutho we-valve kulelo nalelo. lawula into nohlelo.
Into yokulawula Ingxenye yokulahlekelwa komfutho we-valve ohlelweni Izici zokugeleza zevalvu
Ukulawula ukugeleza noma ukulawula izinga loketshezi Ngaphansi kuka-40% Amaphesenti alinganayo
isilawuli sokugeleza noma isilawuli sezinga le-liquid Ngaphezu kuka-40% Linear
ukulawula ukucindezela noma ukulawula izinga lokushisa Ngaphansi kuka-50% Amaphesenti alinganayo
ukulawula ingcindezi noma izinga lokushisa Ngaphezu 50% Linear
Njengoba ukulahlekelwa kwengcindezi yamapayipi kukhuphuka ngokulingana nesikwele sezinga lokugeleza, uma izici zomzimba we-valve zibonisa ushintsho olulula lomugqa, ingcindezi ehlukile ye-valve iyanda lapho izinga lokugeleza lincane, futhi izinga lokugeleza liba. enkulu lapho i-valve ivuleka kancane.Lapho izinga lokugeleza likhulu, ingcindezi ehlukile ye-valve iyancipha.Izinga lokugeleza alikwazi ukulingana ngokuqondile nokuvulwa kwe-valve.Ngenxa yalesi sizathu, inhloso yokuklama isici sephesenti elilinganayo ukwengeza izici zamapayipi kanye nephampu ukuze ubone ukulawula ukugeleza okuzimele ngaphandle kwesilinganiso sokugeleza futhi izinguquko kuphela ngokulingana nokuvuleka kwevalvu.
Ukusebenza kwe
uhlelo lwamapayipi kanye ne-valve yokulawula ukulahlekelwa kwengcindezi
ingakhethwa ngokuya ngenhlanganisela yeyunithi yokushayela kanye nomzimba we-valve.
Inhlanganisela yeyunithi yokushayela kanye nomzimba we-valve kanye nesenzo se-valve (isibonelo se-valve yesihlalo esisodwa)
Isenzo sevalvu sihlanganisa izinhlobo ezintathu: isenzo esiqondile, isenzo sokuhlehla, kanye nesenzo sohlobo lokubamba.Imodi yesenzo esiqondile yedrayivu ye-pneumatic efana nohlobo lwe-diaphragm nohlobo lwesilinda kuyindlela yokuvala i-valve ngokwandisa isignali yokucindezela komoya, eyaziwa nangokuthi "I-AIR TO CLOSE".Indlela yesenzo sokuhlehla iwukuvula ivalvu ngokwandisa isignali yokucindezela komoya, eyaziwa nangokuthi “UMOYA OKUYA KUVULA” noma “I-AIRLESS UKUVALA”.Amasignali asebenza ngogesi angaguqulwa abe amasignali womoya ngumuntu obeka indawo.Uma isignali yokusebenza iphazamiseka noma umthombo womoya uphazamiseka noma ugesi unqanyulwa, sicela ucabangele ukuphepha nokuhluzeka kwenqubo bese ukhetha ukuvala noma ukuvula i-valve.
Isibonelo, lapho ulawula inani le-asidi ngevalvu ngesikhathi sokuxuba amanzi ne-asidi, kuphephile futhi kunengqondo ukuvala i-valve yokulawula i-asidi lapho ulayini wesiginali kagesi unqanyulwa noma ukuvuza kwepayipi lesignali yomoya, umthombo womoya kuphazamiseka, noma amandla anqanyuliwe.I-valve yesenzo sokuhlehlisa.
