Uhlobo lwevalvu yebhola

Ivalve yeBhola edadayo
Ibhola yeivalvu yebholaiyadada. Phantsi kwesenzo soxinzelelo oluphakathi, ibhola inokuvelisa ukufuduka okuthile kwaye icinezele ngokuqinileyo kumphezulu wokutywina wesiphelo sokukhupha ukuqinisekisa ukutywina kwesiphelo sokukhupha. Ivalvu yebhola edadayo inesakhiwo esilula kunye nokusebenza kakuhle kokutywina, kodwa umthwalo webhola ephethe i-medium esebenzayo udluliselwa kwiringi yokutywina ye-outlet, ngoko ke kuyimfuneko ukuqwalasela ukuba izinto zeringi yokutywina zinokumelana nomthwalo osebenzayo we-medium yebhola. Esi sakhiwo sisetyenziswa kakhulu kwiivalvu zebhola ezixineneyo eziphakathi neziphantsi.
Ivalvu yebhola yeTrunnion
Ibhola yeivalvu yebholailungisiwe kwaye ayishukumi phantsi koxinzelelo. Ivalvu yebhola esisigxina inesihlalo sevalvu esintantayo. Emva kokuba icinezelwe yi-medium, isihlalo sevalvu siyahamba, ukuze iringi yokutywina icinezelwe ngokuqinileyo ebholeni ukuqinisekisa ukutywinwa. Iibheringi zihlala zifakelwa kwi-shafts ephezulu nesezantsi ngebhola, kwaye i-torque yokusebenza incinci, efanelekileyo kwiivalvu ezinoxinzelelo oluphezulu kunye nobubanzi obukhulu. Ukuze kuncitshiswe i-torque yokusebenza yevalvu yebhola kunye nokwandisa ukuthembeka kwetywina, kuye kwavela iivalvu zebhola ezitywinwe ngeoyile kutshanje. I-oyile yokuthambisa ekhethekileyo ifakwe phakathi kweendawo zokutywina ukwenza ifilimu yeoyile, ephucula ukusebenza kokutywinwa kwaye inciphise i-torque yokusebenza ifanelekile ngakumbi kwiivalvu zebhola ezinoxinzelelo oluphezulu kunye nobubanzi obukhulu.
Ivalvu yebhola ethambileyo
Ibhola yevalvu yebhola i-elastic. Zombini ibhola kunye neringi yokutywina isihlalo sevalvu zenziwe ngezinto zesinyithi, kwaye uxinzelelo oluthile lokutywina lukhulu kakhulu. Uxinzelelo lwesixhobo ngokwaso alunakwanelisa iimfuno zokutywina, kwaye kufuneka kusetyenziswe amandla angaphandle. Le valve ifanelekile kubushushu obuphezulu kunye nesixhobo sokuxinana esiphezulu. I-elastic sphere ifunyanwa ngokuvula umngxuma we-elastic kwisiphelo esisezantsi sodonga lwangaphakathi lwesixhobo ukuze ufumane ukuxinana. Xa uvala umjelo, sebenzisa intloko ye-wedge yesiqu sevalvu ukwandisa ibhola kwaye ucinezele isihlalo sevalvu ukuze ufumane ukutywina. Ngaphambi kokuba ujike ibhola, khulula intloko ye-wedge, kwaye ibhola iya kubuyela kwimo yayo yokuqala, ukuze kubekho umsantsa omncinci phakathi kwebhola kunye nesihlalo sevalvu, onokunciphisa ukungqubana kunye ne-torque yokusebenza komphezulu wokutywina.
