Uhlobo lwevalve yebhola

Ivalve yeBhola edadayo
Ibhola yeivalve yebholaiyadada.Ngaphantsi kwesenzo soxinzelelo oluphakathi, ibhola inokuvelisa i-displacement ethile kwaye icinezele ngokuqinileyo kwindawo yokutywinwa kwendawo yokuphuma ukuze kuqinisekiswe ukutywinwa kokuphela kokuphuma.Ivalve yebhola edadayo inesakhiwo esilula kunye nokusebenza kakuhle kokutywinwa, kodwa umthwalo webhola ephethe i-medium yokusebenza yonke idluliselwe kwindandatho yokutywina yokuphuma, ngoko ke kuyimfuneko ukuqwalasela ukuba izinto zokutywina ziyakwazi ukumelana nomthwalo wokusebenza ibhola medium.Esi sakhiwo sisetyenziswa ngokubanzi kwiivalvu zebhola eziphakathi kunye neziphantsi.
Ivalve yebhola yetrunnion
Ibhola yeivalve yebholailungisiwe kwaye ayihambi phantsi koxinzelelo.Ivalve yebhola esisigxina inesitulo sevalve edadayo.Emva kokunyanzeliswa yi-medium, isihlalo sevalve siyahamba, ukwenzela ukuba ikhonkco lokutywina ligxininiswe ngokuqinileyo kwibhola ukuqinisekisa ukutywinwa.Iibhere zivame ukufakwa kwi-shafts ephezulu kunye nezantsi kunye nebhola, kwaye i-torque yokusebenza incinci, ifanelekile kwi-high-pressure kunye ne-diameter-diameter valves.Ukuze kuncitshiswe i-torque yokusebenza ye-valve yebhola kunye nokwandisa ukuthembeka kwesitywina, iivalve zebhola ezitywinwe ngeoyile zivele kutshanje.Ioli ekhethekileyo yokuthambisa ijojowe phakathi kweendawo zokutywina ukwenza ifilimu yeoli, eyandisa ukusebenza kokutywinwa kunye nokunciphisa i-torque yokusebenza ifaneleke ngakumbi kwi-high-pressure kunye ne-diameter yebhola ye-valve.
Ivalve yebhola ye-elastic
Ibhola yevalve yebhola ilastiki.Zombini ibhola kunye nomsesane wokutywina wesihlalo sevalve zenziwe ngezinto zentsimbi, kwaye uxinzelelo oluthile lokutywina lukhulu kakhulu.Uxinzelelo oluphakathi ngokwalo alukwazi ukuhlangabezana neemfuno zokutywinwa, kwaye kufuneka kusetyenziswe amandla angaphandle.Le valve ifanelekile kubushushu obuphezulu kunye noxinzelelo oluphakathi.I-elastic sphere ifumaneka ngokuvula i-elastic groove ekupheleni kodonga lwangaphakathi lwe-sphere ukufumana i-elasticity.Xa uvala itshaneli, sebenzisa intloko ye-wedge yesikhondo sevalve ukwandisa ibhola kwaye ucinezele isihlalo sevalve ukufezekisa ukutywinwa.Ngaphambi kokuguqula ibhola, khulula intloko ye-wedge, kwaye ibhola iya kubuyela kwisimo sayo sokuqala, ukuze kubekho umsantsa omncinci phakathi kwebhola kunye nesihlalo sevalve, enokunciphisa ukukhuhla kunye nokusebenza kwetorque yendawo yokutywina.
