Kutheni kufuneka iivalve yeglowubhuiyilwe njengendawo yokungena esezantsi, indawo yokuphuma ephezulu kunye nevalve yeglowubhu edayamitha encinci?Kuyilo kunye nenkqubo yokufakela, i-inlet ephantsi kunye ne-outlet ephezulu idla ngokusetyenziswa, oko kukuthi, i-valve yeglowubhu ihamba isuka ngaphantsi kwe-flap yevalve ukuya ngaphezu kwe-valve flap.Ivalve yeglowubhu enobubanzi obuncinci ine-torque encinci kakhulu kunye netorque encinci yokuvula kunye nokuvala.Naphantsi kwempembelelo yoxinzelelo lokusebenza, impembelelo ekusebenzeni incinci, kuba impembelelo yolwalathiso lokuhamba kwendlela yobunzima bokusebenza inokungahoywa.Ivalve yeglobhu ene-diameter encinci yamkelwe Zizo zonke izakhiwo ezingalinganiyo.Kutheni le nto ivalve yeglowubhu kufuneka iyilwe ibe ne-inlet ephantsi kunye ne-high outlet kunye ne-outlet ephantsi kunye ne-outlet ephezulu?Xa ivaliwe, uxinzelelo oluphakathi lunempembelelo encinci kwi-valve stem kwaye ayiyi kuchaphazela i-valve stem.
Isiqu se-valve siphinde sicwiliselwe phakathi, okungekho lula ukutshatyalaliswa yi-medium, ekhusela ngokufanelekileyo i-valve stem;isakhiwo sokupakisha sikwahlulwe ngokufanelekileyo kwi-medium, iqinisekisa impembelelo ye-medium kwi-packing, kunye nokwandisa ngokufanelekileyo ubomi be-valve stem packing.
Eyona nto ibalulekileyo lukhuseleko.Ukuba i-valve stem iyaphuka okanye ezinye iintsilelo zenzeke, i-valve inokuvula ngokuzenzekelayo ukuthintela uxinzelelo olugqithisileyo lwenkqubo.
Ukusetyenziswa kwe-inlet ephantsi kunye ne-outlet ephezulu kunokuphepha ngokufanelekileyo i-hammer phenomenon yamanzi ye-valve yokuvala.Xa ivaliwe, phantsi kwesenzo soxinzelelo oluphakathi, isantya esihamba phantsi kweflap yokuthambisa asikwazi ukukhawuleza, kwaye ixesha lokuvala lide, kwaye akulula ukwenza isando samanzi kwintando yePhenomenon, ebangela ukungcangcazela kwemibhobho kunye nokuphepha umonakalo zonke izixhobo ezinxulumene nombhobho.
