Uhlobo lwe-valve yebhola

I-Floating Ball Valve
Ibhola le-ivalvu yebholaiyantanta. Ngaphansi kwesenzo sokucindezela okuphakathi, ibhola lingakhiqiza ukufuduka okuthile futhi licindezele ngokuqinile ebusweni bokuvala bokuphela kokuphuma ukuqinisekisa ukuvalwa kokuphela kokuphuma. I-valve yebhola entantayo inesakhiwo esilula kanye nokusebenza okuhle kokuvala, kodwa umthwalo webhola eliphethe i-medium esebenzayo udluliselwa endandatho yokuvala yokuphuma, ngakho-ke kubalulekile ukucabangela ukuthi impahla yendandatho yokuvala ingamelana yini nomthwalo osebenzayo we-medium yebhola. Lesi sakhiwo sisetshenziswa kabanzi kuma-valve ebhola acindezelwe aphakathi naphansi.
I-valve yebhola le-trunnion
Ibhola le-ivalvu yebholaiqinile futhi ayihambi ngaphansi kwengcindezi. I-valve yebhola egxilile inesihlalo se-valve esintantayo. Ngemva kokucindezelwa yi-medium, isihlalo se-valve siyahamba, ukuze indandatho yokuvala icindezelwe ngokuqinile ebholeni ukuqinisekisa ukuvalwa. Ama-bearings avame ukufakwa kuma-shaft aphezulu naphansi ngebhola, futhi i-torque yokusebenza incane, efanele ama-valve anomfutho ophezulu nobubanzi obukhulu. Ukuze kuncishiswe i-torque yokusebenza ye-valve yebhola futhi kwandiswe ukuthembeka kwe-seal, ama-valve ebhola avaliwe ngowoyela avele muva nje. Uwoyela wokugcoba okhethekile ufakwa phakathi kwezindawo zokuvala ukuze kwakhiwe ifilimu kawoyela, okuthuthukisa ukusebenza kokuvala futhi kunciphisa i-torque yokusebenza ifaneleka kakhulu kuma-valve ebhola anomfutho ophezulu nobubanzi obukhulu.
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 ne-medium yokucindezela okuphezulu. I-sphere enwebekayo itholakala ngokuvula umsele onwebekayo ekugcineni okuphansi kodonga lwangaphakathi lwe-sphere ukuze uthole ukuqina. Uma uvala isiteshi, sebenzisa ikhanda le-wedge lesiqu se-valve ukuze wandise ibhola bese ucindezela isihlalo se-valve ukuze uthole ukuqina. Ngaphambi kokuguqula ibhola, khulula ikhanda le-wedge, bese ibhola lizobuyela esimweni salo sokuqala, ukuze kube negebe elincane phakathi kwebhola nesihlalo se-valve, okunganciphisa ukungqubuzana kanye ne-torque yokusebenza kwendawo yokuvala.
