Uhlobo lwe-valve yebhola

Ivalve yebhola elintantayo
Ibhola lei-valve yebholaiyantanta.Ngaphansi kwesenzo sokucindezela okuphakathi, ibhola lingaveza ukugudluka okuthile futhi licindezele ngokuqinile endaweni yokuvala yokuphela kwe-outlet ukuze kuqinisekiswe ukuvaleka kokuphela kokuphumayo.I-valve yebhola elintantayo inesakhiwo esilula kanye nokusebenza kahle kokuvala, kodwa umthwalo webhola eliphethe i-interface yokusebenza wonke udluliselwe endandatho yokuvala i-outlet, ngakho-ke kuyadingeka ukucabangela ukuthi indandatho yokuvala ingakwazi yini ukumelana nomthwalo wokusebenza we-outlet. ibhola medium.Lesi sakhiwo sisetshenziswa kabanzi kuma-valve ebhola aphakathi naphansi.
I-valve yebhola ye-trunnion
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, ama-valve ebhola afakwe uphawu ngamafutha asanda kuvela.Amafutha okugcoba akhethekile ajovwa phakathi kwezindawo zokuvala ukuze enze ifilimu kawoyela, ethuthukisa ukusebenza kokuvala futhi inciphise i-torque esebenzayo ifaneleka kakhulu kuma-valve ebhola anomfutho ophezulu kanye nobubanzi obukhulu.
I-valve yebhola ye-Elastic
Ibhola le-valve yebhola liyanwebeka.Kokubili ibhola nendandatho yokuvala isihlalo se-valve zenziwe ngezinto zensimbi, futhi ingcindezi ethile yokubeka uphawu 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.
