Hlukanisa esakhiweni

I-valve yebhola enengxenye eyodwa iyibhola elihlanganisiwe, indandatho ye-PTFE, kanye ne-lock nut. Ububanzi bebhola buncane kancane kunobe-ipayipi, okufana nevalvu 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 enezicucu ezintathu yakhiwe ngezingxenye ezintathu, ibhonethi ezinhlangothini zombili kanye nomzimba wevalvu ephakathi. Ivalvu yebhola enezicucu ezintathu ihlukile kunevalvu yebhola enezicucu ezimbili kanye nevalvu eyodwa.ivalvu yebholangoba kulula ukuyihlukanisa nokuyinakekela.

Hlukanisa ekucindezelekeni

Ukumelana nengcindezi yevalvu yebhola enezicucu ezintathu kuphakeme kakhulu kunokwevalvu yebhola enezicucu eyodwa nenezicucu ezimbili. Uhlangothi lwangaphandle lwevalvu yebhola eyinhloko enezicucu 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-valve yebhola entantayo: Ibhola le-valve yebhola liyantanta. Ngaphansi kwesenzo sokucindezela okuphakathi, ibhola lingakhiqiza ukufuduka okuthile bese licindezela ngokuqinile ebusweni bokuvala bokuphela kokuphuma ukuqinisekisa ukuthi ukuphela kokuphuma kuvaliwe. I-valve yebhola entantayo inesakhiwo esilula kanye nokusebenza okuhle kokuvala, kodwa umthwalo we-medium esebenzayo ebholeni udluliselwa endandatho yokuvala yokuphuma. Ngakho-ke, kubalulekile ukucabangela ukuthi impahla yendandatho yokuvala ingamelana yini nomthwalo osebenzayo we-medium eyindilinga. 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 kokuthola ingcindezi ye-medium, isihlalo se-valve sizohamba, ukuze indandatho yokuvala icindezelwe ngokuqinile ebholeni ukuqinisekisa ukuvalwa. Ama-bearings avame ukufakwa emigodini ephezulu nephansi yebhola, futhi i-torque yokusebenza incane, efanele ama-valve anomfutho ophezulu kanye nobubanzi obukhulu. Ukuze kuncishiswe i-torque yokusebenza ye-valve yebhola futhi kwandiswe ukuthembeka kwe-seal, kwavela i-valve yebhola evalwe ngowoyela. Kwafakwa uwoyela okhethekile wokugcoba phakathi kwezindawo zokuvala ukuze kwakhiwe ifilimu kawoyela, okwathuthukisa ukusebenza kokuvala futhi kwanciphisa i-torque yokusebenza, okwenza ifaneleke kakhulu ezingcindezini eziphezulu.I-valve yebholayobukhulu.

3. I-valve yebhola enwebekayo: Ibhola le-valve yebhola liyanwebeka. I-sphere kanye nendandatho yokuvala isihlalo se-valve zenziwe ngezinto zensimbi, futhi ingcindezi ethile ye-seal 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 ibhola, bese ibhola lizobuyela esimweni salo sokuqala, ukuze kube negebe elincane phakathi kwebhola 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 sawo sesiteshi. Amavalvu amabili ebhola okugcina asetshenziselwa ukusabalalisa i-medium nokushintsha indlela yokugeleza kwe-medium.
