Yahlula kwisakhiwo

Ivalvu yebhola eneqhekeza elinye yibhola edibeneyo, iringi ye-PTFE, kunye ne-lock nut. Ububanzi bebhola buncinci kancinci kunobo bebhola.umbhobho, efana nevalvu yebhola ebanzi.

Ivalvu yebhola enamacandelo amabini yenziwe ngamacandelo amabini, kwaye isiphumo sokutywina singcono kunesevalvu yebhola eneqhekeza elinye. Ububanzi bebhola bufana nobombhobho, kwaye kulula ukuyiqhekeza kunevalvu yebhola eneqhekeza elinye.

Ivalvu yebhola enamacandelo amathathu yenziwe ngamacandelo amathathu, ibhonethi kumacala omabini kunye nomzimba wevalvu ephakathi. Ivalvu yebhola enamacandelo amathathu yahlukile kwivalvu yebhola enamacandelo amabini kunye nevalvu yenxalenye enye.ivalvu yebholakuba kulula ukuyiqhaqha nokuyilungisa.

Yahlula kuxinzelelo

Ukumelana noxinzelelo lwevalvu yebhola eneziqwenga ezintathu kuphezulu kakhulu kunokwevalvu yebhola eneziqwenga ezimbini kunye neyeziqwenga enye. Icala langaphandle levalvu yebhola eneziqwenga ezintathu liqiniswe ngamabholiti amane, adlala indima entle ekuqiniseni. Umzimba wevalvu yokuphosa ngokuchanekileyo unokufikelela kuxinzelelo lwe-1000psi≈6.9MPa. Kwiingcinezelo eziphezulu, kusetyenziswa imizimba yevalvu eyenziwe ngomatshini.

Ngokwesakhiwo sevalvu yebhola, ingahlulwahlulwa ibe:

1. Ivalvu yebhola edadayo: Ibhola yevalvu yebhola iyadada. Phantsi kwesenzo soxinzelelo oluphakathi, ibhola inokuvelisa ukufuduka okuthile kwaye icinezele ngokuqinileyo kumphezulu wokutywina wesiphelo sokuphuma ukuqinisekisa ukuba isiphelo sokuphuma sivaliwe. Ivalvu yebhola edadayo inesakhiwo esilula kunye nokusebenza kakuhle kokutywina, kodwa umthwalo wesixhobo esisebenzayo ebholeni udluliselwa kwiringi yokutywina yesithuba sokuphuma. Ke ngoko, kuyimfuneko ukuqwalasela ukuba izinto zeringi yokutywina zinokumelana nomthwalo osebenzayo wesixhobo esijikelezayo. Esi sakhiwo sisetyenziswa kakhulu kwiivalvu zebhola ezidanyazayo eziphakathi neziphantsi.

2. Ivalvu yebhola ezinzileyo: Ibhola yevalvu yebhola izinzile kwaye ayishukumi emva kokuba icinezelwe. Ivalvu yebhola ezinzileyo ixhotyiswe ngesihlalo sevalvu esintantayo. Emva kokufumana uxinzelelo lwe-medium, isihlalo sevalvu siya kuhamba, ukuze iringi yokutywina icinezelwe ngokuqinileyo ebholeni ukuqinisekisa ukutywinwa. Iibheringi zihlala zifakelwa kwimivalo ephezulu nesezantsi yebhola, kwaye i-torque yokusebenza incinci, efanelekileyo kwiivalvu ezinoxinzelelo oluphezulu kunye nobubanzi obukhulu. Ukuze kuncitshiswe i-torque yokusebenza yevalvu yebhola kwaye kwandiswe ukuthembeka kwetywina, kwavela ivalvu yebhola etywinwe ngeoyile. Ioyile yokuthambisa ekhethekileyo yafakwa phakathi kweendawo zokutywina ukwenza ifilimu yeoyile, eyaphucula ukusebenza kokutywinwa kwaye yanciphisa i-torque yokusebenza, okwenza ukuba ifaneleke ngakumbi kwiingcinezelo eziphezulu.Ivalvu yebholayodidi.

3. Ivalvu yebhola ethambileyo: Ibhola yevalvu yebhola i-elastic. Isphere kunye neringi yokutywina isihlalo sevalvu zenziwe ngezinto zesinyithi, kwaye uxinzelelo oluthile lweseal lulukhulu kakhulu. Uxinzelelo lwesixhobo ngokwaso alunakwanelisa iimfuno zokutywina, kwaye kufuneka kusetyenziswe amandla angaphandle. Le valve ifanelekile kubushushu obuphezulu kunye nemidiya yoxinzelelo oluphezulu. Isphere ye-elastic yenziwe ngokuvula umngxuma we-elastic kwisiphelo esisezantsi sodonga lwangaphakathi lwesphere ukuze ufumane ukuqina. Xa uvala ipaseji, sebenzisa intloko yesiqu sevalvu ukuze wandise ibhola kwaye ucinezele isihlalo sevalvu ukuze utywine. Khulula intloko ethambileyo ngaphambi kokuba ujikelezise ibhola, kwaye ibhola iya kubuyela kwimo yayo yokuqala, ukuze kubekho umsantsa omncinci phakathi kwebhola kunye nesihlalo sevalvu, nto leyo enokunciphisa ukungqubana komphezulu wokutywina kunye ne-torque yokusebenza.

Iivalvu zebhola zinokwahlulwa zibe ziintlobo ezithe tye, iintlobo ezintathu kunye nohlobo lwe-engile yasekunene ngokwendawo yazo yetshaneli. Ezi valve zimbini zokugqibela zisetyenziselwa ukusasaza i-medium kunye nokutshintsha indlela yokuhamba kwe-medium.
