Izinto ezibalulekileyo zevalvu yebhola ngumzimba wevalvu, isitulo sevalvu, ingqukuva, isiqu sevalvu, kunye nomqheba. Ivalve yebhola ine-sphere njengecandelo layo lokuvala (okanye ezinye izixhobo zokuqhuba). Ijikeleza i-axis yevalve yebhola kwaye iqhutywe sisikhondo sevalve. Isetyenziswa ikakhulu kwimibhobho ukusika, ukusasaza, kunye nokutshintsha indlela yokuhamba kwesixhobo. Abasebenzisi kufuneka bakhethe iintlobo ezahlukeneyo zeevalvu zebhola ngokusekelwe kwiimfuno zabo ngenxa yoluhlu olukhulu lweevalvu zebhola, kubandakanywa nemigaqo yokusebenza eyahlukeneyo, imidiya kunye neendawo zokusebenza. Iivalvu zebhola zihlelwe ngokweendidi ezahlukeneyo ngokusekelwe kwiimeko ezisebenza ngokwenene kwindawo ethile.

Ngokolwakhiwo lunokwahlulwa lube:

1. Ivalve yebhola edadayo

Ibhola edadayo yevalve yebhola. Phantsi kweempembelelo zoxinzelelo oluphakathi, ibhola inokudala ukushukuma okuthile kwaye ityhale ngokuqinileyo kumphezulu wokutywina wesiphelo sokuphuma ukugcina itywina lesiphelo sokuphuma.

Nangona ivalve yebhola edadayo inoyilo oluthe ngqo kunye nobuchule bokutywina obusebenzayo, kubalulekile ukuba kuthathelwe ingqalelo ukuba izinto zeringi yokutywina zinokumelana nomthwalo osebenzayo webhola ephakathi kuba umthwalo wesixhobo sokusebenza kwibhola usasazwa ngokupheleleyo. kumsesane wokutywina wokuphuma. Iivalvu zebhola ezinoxinzelelo oluphakathi nophantsi zidla ngokusebenzisa olu lwakhiwo.

2. Ivalve yebhola ezinzileyo

Emva koxinzelelo, ibhola yevalve yebhola ilungisiwe kwaye ayishukumi. Izihlalo zevalve ezidadayo zibandakanywe nebhola esisigxina kunye neevalvu zebhola. Isihlalo sevalve siyashukuma xa siphantsi koxinzelelo oluphakathi, ukucinezela iringi yokutywina ngokuqinileyo ngokuchasene nebhola ukuqinisekisa ukutywinwa. Ngokuqhelekileyo, iibhola zebhola zifakwe kwi-shafts ephezulu kunye nezantsi, kwaye i-torque yabo encinci yokusebenza ibenza balungele iivalve ezinkulu ezinoxinzelelo oluphezulu.

Ivalve yebhola etywinwe ngeoyile, ifaneleke ngakumbi kwi-high-pressure ye-diameter ye-diameter ye-valve yebhola, iye yavela kwiminyaka yakutshanje ukwenzela ukunciphisa i-torque yokusebenza yevalve yebhola kunye nokwandisa ukufumaneka kwesitywina. ayifaki kuphela ioli ekhethekileyo yokuthambisa phakathi kweendawo zokutywina ukwenza ifilimu yeoli, ephucula ukusebenza kokutywinwa kodwa inciphisa i-torque yokusebenza.

3. Ivalve yebhola ye-elastic

Ibhola elastiki kwivalve yebhola. Ibhola yesitulo sevalve kunye neringi yokutywina zombini zenziwe ngentsimbi, ngoko ke kufuneka uxinzelelo olukhethekileyo lokutywina. Ngokoxinzelelo lwe-medium, amandla angaphandle kufuneka asetyenziswe ukutywina isixhobo kuba uxinzelelo oluphakathi alwanelanga ukwenza njalo. Le valve inokusingatha i-mediums kunye nokushisa okuphezulu kunye noxinzelelo.

Ngokwandisa i-groove e-elastic ekupheleni kwezantsi kwodonga lwangaphakathi lwe-sphere, i-elastic sphere ifumana iimpawu zayo. Intloko emile okwengca yesiqu sevalve kufuneka isetyenziswe ukwandisa ibhola ngelixa uvala itshaneli kwaye ucinezele isihlalo sevalve ukufezekisa ukutywinwa. Khulula intloko emise okweweji kuqala, emva koko ujike ibhola ngelixa ubuyisela iprototype yantlandlolo ukuze kubekho isithuba esincinci kunye nendawo yokutywina ukunciphisa ukukhuhlane kunye netorque yokusebenza phakathi kwebhola kunye nesitulo sevalvu.
