I-Petroleum kunye ne-Petrochemical Check Valve
Iimbonakalo
Umsebenzi wale valve yokukhangela i-swing kukuvumela ukuba i-medium ihambe kwicala elinye kuphela, kunye nokumisa ukuhamba kwelinye icala.Ngokuqhelekileyo, ivalve isebenza ngokuzenzekelayo.Ngaphantsi kwesenzo soxinzelelo lwe-fluid ehamba kwicala elinye, i-valve clack iyavula.Xa i-fluid igeleza kwicala elichaseneyo, itanki yokulungelelanisa isebenza kwisitulo sokulungelelanisa ngoxinzelelo lwe-fluid kunye nobunzima be-flap yokulungelelanisa ukunqumla ukuhamba.
Ivalve yokujonga i-swing ine-hinge mechanism, kwaye ivalve efana nocango iphumle ngokukhululekileyo kumphezulu wesitulo sevalve echongekileyo.Ukuze kuqinisekiswe ukuba i-valve flap inokufikelela kwindawo efanelekileyo yesihlalo somnatha ngalo lonke ixesha, i-valve flap yenzelwe kwindlela ye-hinge, ukwenzela ukuba i-flap yamahhala ibe nendawo eyaneleyo yokujika, kunye ne-flap eguquguqukayo idibanisa ngokubanzi isihlalo sevalve. .Ivalve inokuthi yenziwe ngokupheleleyo ngentsimbi, okanye ifakwe ngesikhumba, irabha okanye i-synthetic coverage kwintsimbi, kuxhomekeke kwiimfuno zokusebenza.Xa ivalve yokujonga ujingi ivulwe ngokupheleleyo, uxinzelelo lolwelo luphantse lungathintelwa, ngoko ke ukuhla koxinzelelo ngevalve kuncinci.

Iimbonakalo
Umsebenzi wale valve yokukhangela yokuphakamisa kukuvumela ukuba i-medium ihambe kwicala elinye kuphela, kwaye imise ukuhamba kwelinye icala.Ngokuqhelekileyo, ivalve isebenza ngokuzenzekelayo.Ngaphantsi kwesenzo soxinzelelo lwe-fluid ehamba kwicala elinye, i-valve clack iyavula.Xa i-fluid igeleza kwicala elichaseneyo, itanki yokulungelelanisa isebenza kwisitulo sokulungelelanisa ngoxinzelelo lwe-fluid kunye nobunzima be-flap yokulungelelanisa ukunqumla ukuhamba.
Ngaphandle kokuba ivalve inokuvulwa kwaye ithotywe ngokukhululekileyo, enye ivalve iyafana neglobhu.Uxinzelelo lolwelo luphakamisa intsimbi yevalve ukusuka kumphezulu wokutywina wesihlalo sevalvu, kwaye isignali ephakathi yokubuya ibangela ukuba iphini elilawulayo liwele umva kwisitulo sevalvu kwaye inqumle ukuhamba.Ngokwemiqathango yokusetyenziswa, i-shunting ingaba yinto yonke yesakhiwo sesinyithi, okanye inokuba luhlobo lwe-rubber inlaying pads okanye amakhonkco erabha kwisakhelo sokudlulisa igama.Njengevalve yeglowubhu, ukudlula kolwelo kwivalve yokukhangela yokuphakamisa kumxinwa, ngoko ke uxinzelelo lokuphakamisa ivalve yokukhangela lukhulu kunolo lwevalve yokujonga ujingi.
