Ukwahlula kwisakhiwo

Ivalve yebhola enye yibhola edibeneyo, i-PTFE ring, kunye ne-lock nut. Idayamitha yebhola incinci kancinci kunolo lweumbhobho, efana nevalve yebhola ebanzi.

Ivalve yebhola enamacandelo amabini yenziwe ngamacandelo amabini, kwaye isiphumo sokutywinwa singcono kuneso siqhekeza esinye sebhola. Idayamitha yebhola iyafana naleyo yombhobho, kwaye kulula ukuyiqhaqha kunevalve yebhola enye.

Ivalve yebhola enamacandelo amathathu yenziwe ngamalungu amathathu, ibhonethi emacaleni omabini kunye nomzimba wevalvu ephakathi. Ivalve yebhola enamacandelo amathathu yahlukile kwivalve yebhola enamacandelo amabini kunye neqhekeza elinyeivalve yebholakuba kulula ukuqhaqha kunye nokugcina.

Yahlula kuxinzelelo

Ukunyanzeliswa koxinzelelo lwe-valve yebhola yebhola emithathu kuphezulu kakhulu kunomnye kunye neebhola ezimbini zebhola. Icala langaphandle le-valve yebhola yebhola emithathu ephambili igxininiswe ngamabholiti amane, adlala indima enhle ekuqiniseni. Umzimba wevalve yokuphosa echanekileyo unokufikelela kuxinzelelo lwe-1000psi≈6.9MPa. Kuxinzelelo oluphezulu, imizimba yevalvu eyenziweyo iyasetyenziswa.

Ngokwesakhiwo sevalve yebhola, inokwahlulwa ibe:

1. Ivalve yebhola edadayo: Ibhola yevalve yebhola iyadada. Ngaphantsi kwesenzo soxinzelelo oluphakathi, ibhola inokuvelisa i-displacement ethile kwaye icinezele ngokuqinileyo kwindawo yokutywinwa kwendawo yokuphuma ukuze kuqinisekiswe ukuba isiphelo sokuphuma sivalwe. Ivalve yebhola edadayo inesakhiwo esilula kunye nokusebenza kakuhle kokutywinwa, kodwa umthwalo womsebenzi ophakathi ebholeni wonke ugqithiselwa kumsesane wokutywina wokuphuma. Ngoko ke, kuyimfuneko ukuqwalasela ukuba izinto zokutywina ziyakwazi ukumelana nomthwalo osebenzayo we-spherical medium. Esi sakhiwo sisetyenziswa ngokubanzi kwiivalvu zebhola eziphakathi kunye neziphantsi.

2. Ivalve yebhola esisigxina: Ibhola yevalve yebhola izinzileyo kwaye ayishukumi emva kokucinezelwa. Ivalve yebhola esisigxina ixhotyiswe ngesitulo sevalve edadayo. Emva kokufumana uxinzelelo lwe-medium, isihlalo se-valve siya kuhamba, ukwenzela ukuba umsesane wokutywina ugxininiswe ngokuqinileyo kwibhola ukuqinisekisa ukutywinwa. Ukubethelwa ngokuqhelekileyo kufakwe kwi-shafts ephezulu kunye nesezantsi yebhola, kwaye i-torque yokusebenza incinci, ifanelekile kwi-high-pressure kunye ne-diameter-diameter valves. Ukuze kuncitshiswe i-torque yokusebenza yevalve yebhola kunye nokwandisa ukuthembeka kwesitywina, i-valve yebhola etywinwe ngeoli yavela. Ioli ekhethekileyo yokuthambisa yafakwa phakathi kweendawo zokutywina ukuze zenze ifilimu yeoli, eyaphucula ukusebenza kokutywinwa kunye nokunciphisa i-torque yokusebenza, okwenza ukuba ifaneleke ngakumbi kuxinzelelo oluphezulu.Ivalve yebholayomgangatho.

3. Ivalve yebhola enwebekayo: Ibhola yevalve yebhola ilastiki. I-sphere kunye neseyili yokutywina isihlalo sevalve zenziwe ngezinto zetsimbi, kwaye uxinzelelo oluthile lwetywina lukhulu kakhulu. Uxinzelelo oluphakathi ngokwalo alukwazi ukuhlangabezana neemfuno zokutywinwa, kwaye kufuneka kusetyenziswe amandla angaphandle. Le valve ifanelekile kubushushu obuphezulu kunye neendaba zoxinzelelo oluphezulu. I-elastic sphere yenziwa ngokuvula i-elastic groove kwisiphelo esisezantsi sodonga lwangaphakathi lwe-sphere ukufumana u-elasticity. Xa uvala ipaseji, sebenzisa intloko emise okwe wedge yesikhondo sevalve ukwandisa ibhola kwaye ucinezele isihlalo sevalve ukutywina. Khulula intloko emise okwe wedge phambi kokuba ujikelezise ibhola, kwaye ibhola iya kubuyela kwimo yayo yokuqala, ukuze kubekho umsantsa omncinci phakathi kwebhola kunye nesihlalo sevalve, enokunciphisa ukukhuhlana komphezulu wokutywina kunye netorque yokusebenza.

Iivalvu zebhola zinokwahlulwa zibe luhlobo oluthe ngqo, uhlobo lweendlela ezintathu kunye nohlobo lwe-angle ekunene ngokwendawo yetshaneli. Iivalvu ezimbini zokugqibela zebhola zisetyenziselwa ukusasaza i-medium kunye nokutshintsha i-flow direction ye-medium.
