Ivalve yebhabhathane yeTaike inokohlulwa ibe ivelufa yebhabhathane yepneumatic, ivalve yebhabhathane yombane, ivalve yebhabhathane yezandla, njl njl. vala, kwaye ulawule umjelo wolwelo. Ipleyiti yebhabhathane yevalve yebhabhathane ifakwe kwicala elinobubanzi bombhobho. Kwijelo le-cylindrical lomzimba wevalve yebhabhathane, ipleyiti yebhabhathane emile idisc ijikeleza i-axis, kunye ne-engile yokujikeleza phakathi kwe-0 ° kunye ne-90 °. Xa ukujikeleza kufikelela kwi-90 °, ivalve ivuleke ngokupheleleyo. Ivalve yebhabhathane, ekwaziwa ngokuba yivalve yeflap, sisakhiwo esilula esilawulayo kwaye ingasetyenziselwa ukutshintsha ulawulo loxinzelelo oluphantsi lombhobho weendaba. Ivalve yebhabhathane (isiNgesi: ivelufa yebhabhathane) ibhekisa kudidi lwesivalo apho indawo yokuvala (idiski okanye idiski) iyidiski ejikeleza iaxis yevalve ukufikelela ukuvuleka nokuvala. Isebenza ikakhulu njengevalve yokuvala kunye ne-throttling kwimibhobho. Ivalve yebhabhathane evula kunye nenxalenye yokuvala yipleyiti yebhabhathane emilisekileyo ejikeleza i-axis yayo ngaphakathi kumzimba wevalvu ukufezekisa injongo yokuvula, ukuvala okanye ukulungisa. Ivalve yebhabhathane idla ngokuba ngaphantsi kwe-90 ° ukusuka ekuvulekeni ngokupheleleyo ukuya ekuvaleni ngokupheleleyo, kwaye ivalve yebhabhathane kunye nesiqu azinawo amandla okuzivalela. Ukuze ubeke ipleyiti yebhabhathane, isinciphisi segiya leentshulube kufuneka sifakwe kwisiqu sevalve. Ukusetyenziswa kokunciphisa i-worm gear akugcini nje ukwenza ukuba i-butterfly plate ibe namandla okuzivalela kwaye imise kuyo nayiphi na indawo, kodwa iphucula ukusebenza kwevalve. Iimpawu zeevalvu zebhabhathane kwimizi-mveliso kukumelana nobushushu obuphezulu, uluhlu loxinzelelo oluphezulu, idiameter enkulu ebizwa ngokuba yi-carbon steel body, kunye nentsimbi yentsimbi endaweni yeringi yerabha yokutywinwa kwepleyiti yevalve. Iivalvu zebhabhathane ezinkulu ezinobushushu obuphezulu zenziwa ngokuwelda iipleyiti zentsimbi kwaye zisetyenziswa ikakhulu kwimibhobho yerhasi yobushushu obuphakathi kunye nemibhobho yerhasi.
Iivalve zebhabhathane zinokwahlulwa zibe luhlobo lwepleyiti ye-offset, uhlobo lwepleyiti ethe nkqo, uhlobo lwepleyiti ethambekele, kunye nohlobo lwe-lever ngokwendlela yazo yesakhiwo. Ngokwefomu yokutywina, inokwahlulwa ibe ziindidi ezimbini: ivalwe ngokufanelekileyo kwaye ivalwe nzima. Uhlobo lokutywina oluthambileyo luqhele ukusebenzisa ukutywinwa kweringi yerabha, ngelixa uhlobo lokutywina olulukhuni luqhele ukusebenzisa ukutywinwa komsesane wentsimbi. Ngokohlobo loqhagamshelwano, lunokwahlulwa lube ludibaniso lwe-flange kunye noqhagamshelo lwe-wafer; Ngokwendlela yothumelo, inokwahlulwa ibe ziindidi ezininzi: i-manual, i-gear transmission, i-pneumatic, i-hydraulic, kunye nombane.
1、 Izinto eziluncedo kwiiVavu zebhabhathane
1. Ukuvula nokuvala ngokukhawuleza kunye nokukhawuleza, ukonga abasebenzi, ukuxhathisa ulwelo oluphantsi, kwaye kunokusebenza rhoqo.
2. Isakhiwo esilula, ubungakanani obuncinci, kunye nobunzima obulula.
3. Inokuthutha udaka kwaye igcine olona lwelo luncinane emlonyeni wombhobho.
4. Ngaphantsi koxinzelelo oluphantsi, ukutywinwa okulungileyo kunokufezekiswa.
5. Ukusebenza kakuhle tuning.
2, Ukungalungi kweeVavu zeBhava
1. Uxinzelelo lokusebenza kunye noluhlu lweqondo lokushisa lincinci.
2. Ukusebenza kakubi kokutywinwa.
3、 Ukufakwa kunye nokugcinwa kweevalvu zebhabhathane
1. Ngethuba lofakelo, i-disc ye-valve kufuneka imiswe kwindawo evaliweyo.
2. Isikhundla sokuvula kufuneka sinqunywe ngokwe-angle yokujikeleza ye-butterfly plate.
3. Iivalvu zebhabhathane ezineevalve zokudlula kufuneka zivulwe phambi kokuba zivulwe.
4. Ufakelo kufuneka luqhutywe ngokwemiyalelo yokufakela umenzi, kwaye iivalve zebhabhathane ezinzima kufuneka zibe nesiseko esiqinileyo.
5. Ipleyiti yebhabhathane yevalve yebhabhathane ifakwe kwicala elinobubanzi bombhobho. Kwijelo le-cylindrical lomzimba wevalve yebhabhathane, ipleyiti yebhabhathane emile idisc ijikeleza i-axis, kunye ne-engile yokujikeleza phakathi kwe-0 ° kunye ne-90 °. Xa ukujikeleza kufikelela kwi-90 °, ivalve ivuleke ngokupheleleyo.
6. Ukuba i-valve ye-butterfly iyadingeka ukulawula ukuhamba, into ephambili kukuba ukhethe ubungakanani obuchanekileyo kunye nohlobo lwevalve. Umgaqo wokwakhiwa kweevalve zebhabhathane ufanelekile ngokukodwa ukwenza iivalve ezinobubanzi obukhulu. Iivalvu zebhabhathane azisetyenziswa ngokubanzi kwipetroleum, igesi, imichiza, unyango lwamanzi nakwamanye amashishini ngokubanzi, kodwa zikwasetyenziswa kwinkqubo yokupholisa yamanzi kwisikhululo samandla obushushu.
7. Zimbini iivalve zebhabhathane ezisetyenziswa ngokuqhelekileyo: ivalufa yohlobo lwebhabhathane kunye nevalve yohlobo lwebhabhathane. Ivalve yohlobo lwebhabhathane yivalve edityaniswe phakathi kweeflange zemibhobho emibini kusetyenziswa iibholithi ezinentloko ezimbini. Ivalve yohlobo lwebhabhathane yivalve eneflange, kwaye iiflange kuzo zombini iziphelo zevalve ziqhagamshelwe kwiflange yombhobho kusetyenziswa iibholithi.
8. Ipleyiti yebhabhathane yevalve yebhabhathane ifakwe kumda wecala lombhobho. Kwijelo le-cylindrical lomzimba wevalve yebhabhathane, ipleyiti yebhabhathane emile idisc ijikeleza i-axis, kunye ne-engile yokujikeleza phakathi kwe-0 ° kunye ne-90 °. Xa ukujikeleza kufikelela kwi-90 °, ivalve ivuleke ngokupheleleyo.
