Ukwahlula kwisakhiwo

Ivalve yebhola enye yibhola edibeneyo, i-PTFE ring, kunye ne-lock nut. Ububanzi bebhola buncinci kancinci kunombhobho, obufana 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. Isiqwenga esithathuivalve yebholayahlukile kwivalve yebhola enamacandelo amabini kunye nevalve yebhola enye kuba kulula ukuyiqhaqha kunye nokugcina.

Yahlula kuxinzelelo

Ukunyanzeliswa koxinzelelo lweentlobo ezintathu kuphezulu kakhulu kunomnye kunye neebini ezimbiniiivalve 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 wesphere ephethe i-medium yokusebenza ugqithiselwa kwikhonkco lokutywina lokuphuma, ngoko ke kuyimfuneko ukuqwalasela ukuba izinto zokutywina ziyakwazi ukumelana nomthwalo wokusebenza iSphere 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 koxinzelelo lwe-medium, isihlalo sevalve sihamba, ukwenzela ukuba ikhonkco lokutywina licinezele ngokuqinileyo kwibhola ukuqinisekisa ukutywinwa. Iibheringi zivame ukufakwa kwi-shafts ephezulu kunye nesezantsi kwi-sphere, kwaye i-torque yokusebenza incinci, ifanelekile kwi-high-pressure kunye ne-diameter-diameter valves. Ukuze kuncitshiswe i-torque yokusebenza yevalve yebhola kunye nokwandisa ukuthembeka kwetywina, iivalve zebhola ezitywinwe ngeoyile zavela. 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 yebhola yomgangatho.

3. Ivalve yebhola enwebekayo: 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 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 ingqukuva, kwaye ingqukuva iya kubuyela kwimo yayo yokuqala, ukuze kubekho umsantsa omncinci phakathi kwengqukuva 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. Ixesha lamvaiivalve ezimbini zebholazisetyenziselwa ukusasaza i-medium kunye nokutshintsha i-flow direction ye-medium.
