isakhiwo

Ukusebenza kokuvala kuhle, kodwa umthwalo wendilinga ephethe isisetshenziswa sokusebenza wonke udluliselwa eringini yokuvala yokuphumayo.Ngakho-ke, kuyadingeka ukucabangela ukuthi impahla yendandatho yokuvala ingakwazi ukumelana nomthwalo wokusebenza we-sphere medium.Uma ingaphansi kokushaqeka komfutho ophezulu, i-sphere ingase ishintshe..Lesi sakhiwo ngokuvamile sisetshenziselwa ama-valve ebhola aphakathi nendawo naphansi.

Ibhola lei-valve yebholaiyalungiswa futhi ayinyakazi ngaphansi kwengcindezi.I-valve yebhola engashintshi inesihlalo se-valve esintantayo.Ngemuva kokucindezelwa yi-medium, isihlalo se-valve siyanyakaza, ukuze indandatho yokuvala icindezelwe ngokuqinile ebhola ukuze kuqinisekiswe ukuvala.Ama-bearings avame ukufakwa ku-shafts ephezulu nangaphansi ngebhola, futhi i-torque yokusebenza incane, efanelekile kuma-valve aphezulu kanye nobubanzi obukhulu.

Ukuze kuncishiswe i-torque yokusebenza ye-valve yebhola futhi kwandiswe ukuthembeka kophawu, kuye kwavela i-valve yebhola evalwe ngamafutha, engagcini nje ngokujova uwoyela okhethekile wokugcoba phakathi kwezindawo zokuvala ukuze wenze ifilimu kawoyela, engagcini nje ngokuthuthukisa ukusebenza kokuvala, kodwa futhi kunciphisa i-torque yokusebenza.Ifanele umfutho ophezulu kanye nama-valve amabhola amakhulu.

ukunwebeka

Ibhola le-valve yebhola liyanwebeka.Kokubili ibhola nendandatho yokuvala isihlalo se-valve zenziwe ngezinto zensimbi, futhi ingcindezi ethile yokuvala inkulu kakhulu.Ingcindezi ye-medium ngokwayo ayikwazi ukuhlangabezana nezidingo zokuvala, futhi amandla angaphandle kufanele asetshenziswe.Le valve ifanele izinga lokushisa eliphezulu kanye ne-high pressure medium.

I-elastic sphere itholakala ngokuvula i-elastic groove engxenyeni engezansi yodonga lwangaphakathi lwendilinga ukuze kutholwe ukunwebeka.Lapho uvala isiteshi, sebenzisa inhloko ye-wedge yesiqu se-valve ukwandisa ibhola bese ucindezela isihlalo se-valve ukuze ufinyelele ukuvala.Ngaphambi kokuguqula ibhola, khulula ikhanda le-wedge, futhi ibhola lizobuyela esimweni salo sokuqala, ukuze kube negebe elincane phakathi kwebhola nesihlalo se-valve, okunganciphisa ukungqubuzana nokusebenza kwe-torque yendawo yokuvala.
