Hlukanisa esakhiweni

I-valve yebhola enengxenye eyodwa iyibhola elihlanganisiwe, indandatho ye-PTFE, kanye ne-lock nut. Ububanzi bebhola buncane kancane kunobepayipi, obufana ne-valve yebhola ebanzi.

Ivalvu yebhola enezicucu ezimbili yakhiwe ngezingxenye ezimbili, futhi umphumela wokuvala ungcono kunowevalvu yebhola enezicucu eyodwa. Ububanzi bebhola bufana nobepayipi, futhi kulula ukuyihlukanisa kunevalvu yebhola enezicucu eyodwa.

Ivalvu yebhola enezingcezu ezintathu yakhiwe ngezingxenye ezintathu, ibhonethi izinhlangothi zombili kanye nomzimba wevalvu ephakathi.ivalvu yebholaihlukile kwivalvu yebhola enezicucu ezimbili kanye nevalvu yebhola enezicucu eyodwa ngoba kulula ukuyihlukanisa nokuyinakekela.

Hlukanisa ekucindezelekeni

Ukumelana nengcindezi yohlobo lwezingcezu ezintathu kuphakeme kakhulu kunokwezingcezu eyodwa nezingcezu ezimbiliamavalvu ebholaUhlangothi lwangaphandle lwevalvu yebhola eyinhloko enezingcezu ezintathu luqiniswe ngamabhawodi amane, adlala indima enhle ekuqiniseni. Umzimba wevalvu yokuphonsa ngokunemba ungafinyelela ingcindezi engu-1000psi≈6.9MPa. Ngezingcindezi eziphakeme, kusetshenziswa imizimba yevalvu eyenziwe ngobumba.

Ngokwesakhiwo se-ball valve, ingahlukaniswa ibe:

1. I-Floating ball valve: Ibhola le-ball valve liyantanta. Ngaphansi kwesenzo sokucindezela okuphakathi, ibhola lingakhiqiza ukufuduka okuthile bese licindezela ngokuqinile ebusweni bokuvala bokuphela kokuphuma ukuqinisekisa ukuthi ukuphela kokuphuma kuvaliwe. I-floating ball valve inesakhiwo esilula kanye nokusebenza okuhle kokuvala, kodwa umthwalo we-sphere ophethe i-medium esebenzayo wonke udluliselwa eringini yokuvala yokuphuma, ngakho-ke kubalulekile ukucabangela ukuthi impahla ye-sealing ring ingamelana yini nomthwalo osebenzayo we-sphere medium. Lesi sakhiwo sisetshenziswa kabanzi kuma-valve ebhola acindezelwe aphakathi naphansi.

2. I-valve yebhola elungisiwe: Ibhola le-valve yebhola liqinile futhi alinyakazi ngemva kokucindezelwa. I-valve yebhola elungisiwe ifakwe isihlalo se-valve esintantayo. Ngemva kokucindezela kwe-medium, isihlalo se-valve siyahamba, ukuze indandatho yokuvala icindezelwe ngokuqinile ebholeni ukuqinisekisa ukuvalwa. Ama-bearings avame ukufakwa emigodini ephezulu nephansi ye-sphere, futhi i-torque yokusebenza incane, efanelekile kuma-valve anomfutho ophezulu kanye nobubanzi obukhulu. Ukuze kuncishiswe i-torque yokusebenza ye-valve yebhola futhi kwandiswe ukuthembeka kwe-seal, kwavela ama-valve ebhola avaliwe ngamafutha. Kwafakwa uwoyela okhethekile wokugcoba phakathi kwezindawo zokuvala ukuze kwakhiwe ifilimu kawoyela, okwathuthukisa ukusebenza kokuvala futhi kwanciphisa i-torque yokusebenza, okwenza ifaneleke kakhulu ekucindezelweni okuphezulu. I-valve yebhola ye-caliber.

3. I-valve yebhola enwebekayo: Ibhola le-valve yebhola liyanwebeka. Kokubili ibhola kanye nendandatho yokuvala isihlalo se-valve kwenziwe ngezinto zensimbi, futhi ingcindezi ethile yokuvala inkulu kakhulu. Ingcindezi ye-medium ngokwayo ayikwazi ukuhlangabezana nezidingo zokuvala, futhi amandla angaphandle kumele asetshenziswe. Le valve ifanele ukushisa okuphezulu kanye nemidiya yokucindezela okuphezulu. I-sphere enwebekayo yenziwa ngokuvula umsele onwebekayo ekugcineni okuphansi kodonga lwangaphakathi lwe-sphere ukuze uthole ukuguquguquka. Uma uvala indlela, sebenzisa ikhanda elinomumo we-wedge lesiqu se-valve ukuze wandise ibhola bese ucindezela isihlalo se-valve ukuze uvale. Khulula ikhanda elinomumo we-wedge ngaphambi kokujikeleza i-sphere, bese i-sphere izobuyela esimweni sayo sokuqala, ukuze kube negebe elincane phakathi kwe-sphere nesihlalo se-valve, okunganciphisa ukungqubuzana kwendawo yokuvala kanye ne-torque yokusebenza.

Amavalvu ebhola angahlukaniswa ngohlobo oluqondile, uhlobo olunezindlela ezintathu kanye nohlobo lwe-engeli yesokudla ngokuya ngesimo sesiteshi sawo.amavalvu amabili ebholazisetshenziselwa ukusabalalisa i-medium nokushintsha indlela yokugeleza kwe-medium.
