Yahlula kwisakhiwo

Ivalvu yebhola eneqhekeza elinye yibhola edibeneyo, iringi ye-PTFE, kunye ne-lock nut. Ububanzi bebhola buncinci kancinci kunobo bombhobho, obufana 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 yebholayahlukile kwivalvu yebhola enamacandelo amabini kunye nevalvu yebhola enye kuba kulula ukuyiqhaqha nokuyilungisa.

Yahlula kuxinzelelo

Ukumelana noxinzelelo lohlobo lweziqwenga ezintathu kuphezulu kakhulu kunoko kwecandelo elinye necandelo ezimbini.iivalvu zebholaIcala langaphandle levalvu yebhola ephambili enamacandelo amathathu liqiniswe ngamabholithi 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 iyadadayo. 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 wesphere ephethe i-medium esebenzayo udluliselwa kwiringi yokutywina ye-outlet, ngoko ke kuyimfuneko ukuqwalasela ukuba izinto zeringi yokutywina zinokumelana nomthwalo osebenzayo we-medium yesphere. 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 koxinzelelo lwe-medium, isihlalo sevalvu siyashukuma, ukuze iringi yokutywina icinezelwe ngokuqinileyo ebholeni ukuqinisekisa ukutywinwa. Iibheringi zihlala zifakelwa kwimijikelo ephezulu nesezantsi yesphere, kwaye itorque yokusebenza incinci, efanelekileyo kwiivalvu ezinoxinzelelo oluphezulu kunye nobubanzi obukhulu. Ukuze kuncitshiswe itorque yokusebenza yevalvu yebhola kwaye konyuswe ukuthembeka kwetywina, kwavela iivalvu zebhola ezitywinwe ngeoyile. Ioyile yokuthambisa ekhethekileyo yafakwa phakathi kweendawo zokutywina ukwenza ifilimu yeoyile, eyaphucula ukusebenza kokutywinwa kwaye yanciphisa itorque yokusebenza, okwenza ukuba ifaneleke ngakumbi kwiingcinezelo eziphezulu. Ivalvu yebhola ye-caliber.

3. 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 nemidiya yoxinzelelo oluphezulu. Isphere ye-elastic yenziwe ngokuvula umngxuma we-elastic kwisiphelo esisezantsi sodonga lwangaphakathi lwesphere ukuze ufumane ukuthamba. Xa uvala ipaseji, sebenzisa intloko yesiqu sevalvu ukuze wandise ibhola kwaye ucinezele isihlalo sevalvu ukuze uyivale. Khulula intloko ethambileyo ngaphambi kokuba ujikelezise isphere, kwaye isphere iya kubuyela kwimo yayo yokuqala, ukuze kubekho umsantsa omncinci phakathi kwesphere kunye nesihlalo sevalvu, 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.iivalvu ezimbini zebholazisetyenziselwa ukusasaza i-medium kunye nokutshintsha indlela yokuhamba kwe-medium.
