Kulula ukusebenza, vula ngokukhululeka, ukunyakaza okuguquguqukayo nokuthembekile;Ukuhlanganiswa kwe-disc nokugcinwa kulula, isakhiwo sokubeka uphawu sinengqondo, futhi ukushintshwa kwendandatho yokubeka uphawu kulula futhi kuyasebenza.Isakhiwo: Ikakhulukazi yakhiwe umzimba we-valve, i-disc, indandatho yokuvala, isiqu, ukusekela, indlala ye-valve, isondo lesandla, i-flange, i-nati, isikulufu sokumisa nezinye izingxenye.Lolu hlobo lwe-valve ngokuvamile kufanele lufakwe ngokuvundlile epayipini.
I-valve yokukhipha isetshenziswa kakhulu ekukhipheni, ukukhipha, ukusampula kanye nemisebenzi yokuvalwa kwamahhala ngaphansi kwe-reactor, ithangi lokugcina nezinye iziqukathi.I-flange engezansi ye-valve ishiselwe phansi kwethangi nezinye iziqukathi, ngaleyo ndlela kuqedwe into evamile eyinsalela yenqubo yemidiya endaweni yokuphuma.I-valve yokukhipha ngokuvumelana nezidingo zesimo sangempela, umklamo wesakhiwo esiphansi uwuhlobo oluphansi oluyisicaba, umzimba we-valve unomumo we-V, futhi uhlinzeka ngezinhlobo ezimbili zediski yemodi yokusebenza ephakamisayo neyokuwayo.Umgodi womzimba we-valve onokumelana nokuguguleka, ukumelana nokugqwala kwendandatho yophawu, lapho kuvulwa umzuzu we-valve, kungavikela umzimba we-valve ukuthi ungagezwa yi-medium, ukugqwala, kanye nokwelashwa okukhethekile kwendandatho yophawu, ukuze ukuqina kwendawo. ifinyelela ku-HRC56-62, enokumelana nokuguga okuphezulu, umsebenzi wokumelana nokugqwala, uphawu lwe-disc ngokwesidingo sekhava idlula i-carbide enosimende, i-seal pair isebenzisa uphawu lomugqa, ukuqinisekisa ukuthembeka kophawu, Futhi kuvimbele izibazi.Ngasikhathi sinye, thatha idizayini ye-valve ye-stroke emfushane.
Umehluko phakathi kwaphezulu naphansi:
Ivalve yokukhipha eya phezulu ukuze ibhola likhuphuke ukuze liphume, ivalvu ekhulayo ephansi ukuze ibhola iwe ukuze liphume.
I-valve yokukhipha eyaphezulu iyi-bore egcwele, i-valve yokukhipha ephansi yohlobo oluvulekile ijwayelekile encishisiwe, faka i-kettle end flange inkulu.Isiqondiso sokushintsha i-Disc sihlukile: I-valve yokukhipha phezulu, njengoba igama lisho, ivula i-disc futhi iphakamise i-reactor ephezulu;i-valve yokukhipha eya phansi, njengoba igama lisho, ivula i-disc futhi yehlise igumbi le-valve.Ngenxa yalesi sizathu, izinga le-flange kufanele lenyuswe ukwandisa isikhala segumbi le-valve.I-stroke yokuvula nokuvala ihlukile, futhi usayizi wokufaka une-stroke encane yokuvula nokuvala kanye nokuphakama okuncane kokufakwa kwama-valve aphezulu naphansi okuvula nokuvala.Ukuphakama kokufakwa kwesakhiwo senduku ejikelezayo kuncane kakhulu, futhi i-plunger ijikeleza kuphela inqubo yokuvula nokuvala.Inquma indawo yokuvula nokuvala ye-valve ngokusho kwesibonisi sokuvula nokuvala.I-valve yokuvula nokuvala i-torque eya phezulu ivulekele i-disc ukuze inyuse i-valve, i-valve idinga ukunqoba amandla aphakathi nendawo lapho ivuliwe, futhi i-torque yokuvala inkulu uma ivuliwe.
Uhlobo oluya phansi kanye nevalvu yokukhipha i-plunger ivula i-disc i-valve yokuhamba eya phansi.Uma ivuliwe, isiqondiso sokunyakaza siyafana namandla aphakathi, ngakho-ke i-torque yokuvala incane uma ivuliwe.
Nakuba i-valve yokukhipha eya phezulu kanye ne-valve yokukhipha eya phansi ihluke kakhulu, izici zabo ezivamile ibanga eliseduze phakathi kwesihlalo se-valve kanye ne-flange yokugcina, ukugcinwa okuncane kwezinto ezibonakalayo, isakhiwo esihlangene kanye nokusebenza kokuvala okuphakeme.Zisetshenziswa embizeni yokusabela yemboni yamakhemikhali emihle, imboni yezemithi kanye nemboni yamakhemikhali, futhi ingasetshenziswa ekuthuthweni okuphakathi kwezinhlayiya ezinhle nezithambile.
