Ivalvu yeglobu yebhonethi evalwe ngomfutho iwuhlobo lwevalvu yembulunga enomklamo wokuvalwa kokucindezela kubhonethi, ohlinzeka ngophawu oluthembekile lwezinhlelo zokusebenza zokucindezela okuphezulu.Lo mklamo uvame ukusetshenziswa ezimbonini lapho ukugcina uphawu oluqinile ngaphansi kwengcindezi ephezulu kubalulekile, njengasemikhakheni kawoyela negesi, i-petrochemical, neyokukhiqiza amandla.Idizayini yebhonethi evalwe ngomfutho ihluke ekucushweni kwebhonethi eboshwe ngokwesiko ngokusebenzisa uhlobo lwensimbi. -ukuvalwa kwensimbi phakathi kwebhonethi nomzimba we-valve, okususa isidingo se-gasket.Le ndlela yokuvala ithuthukisa ikhono le-valve lokumelana nokucindezela okukhulu futhi isiza ekuvimbeleni ukuvuza.Amavalvu eglobhu ebhonethi evalwe ukucindezela avame ukusetshenziswa ezinhlelweni ezibucayi lapho ukuphepha, ukwethembeka, nokusebenza ngaphansi kwezimo ezimbi kakhulu kubaluleke kakhulu.Idizayini yokuvala ingcindezi iqinisekisa ukuthi i-valve ingakwazi ukugcina ubuqotho bayo futhi ivaleke ngisho nalapho ibhekene namazinga okucindezela adingekayo.Lapho ucacisa noma ukhetha i-valve yeglobhu yebhonethi evalwe ngomfutho, kubalulekile ukucabangela izici ezifana nesilinganiso esiphezulu sokucindezela, izidingo zokushisa, ukuhambisana kwezinto ezibonakalayo. , kanye nezindinganiso ezithile zemboni noma iziqondiso ezingase zisebenze esicelweni esihlosiwe.Uma uneminye imibuzo mayelana namavalvu eglobhu ebhonethi evalwe ukucindezela noma uma udinga usizo nganoma yiziphi izihloko ezihlobene, zizwe ukhululekile ukucela ulwazi olwengeziwe.
1. Umzimba we-valve kanye nefomu lokuxhuma ikhava ye-valve: ikhava ye-valve yokuvala i-self-pressure.
2. Izingxenye zokuvula nokuvala (i-valve disc) design: ngokuvamile zisebenzisa i-disc ye-valve yophawu lwendiza, ngokwezidingo zekhasimende kanye nezimo zangempela zokusebenza zidinga ukusebenzisa i-taper seal valve disc, indawo yokuvala ingaba ngaphezu kwezinto zegolide zokushisela noma izinto ezingezona ezensimbi ezihlanganisiwe kuzimfuneko zomsebenzisi.
3. Ikhava ye-valve ifomu le-gasket eliphakathi: indandatho yensimbi yokuzicindezela ngokuzikhandla.
4. Ukupakisha uphawu: I-graphite eguquguqukayo ivame ukusetshenziswa njengempahla yokupakisha, futhi i-PTFE noma impahla yokupakisha eyinhlanganisela inganikezwa ngokwezidingo zomsebenzisi.Ubukhulu obungaphezulu bokupakisha kanye nokuxhumana kwebhokisi lokuphakela kungu-0.2um, okungaqinisekisa ukuthi isiqu se-valve kanye nendawo yokuthintana yokupakisha kusondelene kodwa kuzungezisa ngokukhululekile, futhi isiqu se-valve esivala ubuso obumaholo obungu-0.8μm ngemva komshini oqondile ungaqinisekisa ukubekwa uphawu okuthembekile kwesiqu se-valve.
5. Uhlelo lomthelela wokupakisha okulayishwe entwasahlobo: Uma kudingwa amakhasimende, isistimu yomthelela yokupakisha okulayishwe entwasahlobo ingasetshenziswa ukuthuthukisa ukuqina nokuthembeka kokupakisha izimpawu.
6. Indlela yokusebenza: ngaphansi kwezimo ezijwayelekile, i-hand wheel drive noma i-gear drive mode ingasetshenziswa ngokwezidingo zomsebenzisi, i-sprocket drive noma idrayivu kagesi.
7. Idizayini ye-reverse seal: Wonke ama-valve embulunga anikezwe inkampani yethu anomklamo wophawu oluhlehlayo, ngaphansi kwezimo ezijwayelekile, idizayini yesihlalo se-carbon steel globe valvu yamukela uhlaka oluhlukanisiwe oluhlanekezela uphawu, kanye nophawu olubuyela emuva lwembulunga yensimbi engagqwali. i-valve icutshungulwa ngokuqondile noma icutshungulwe ngemuva kokushisela.Lapho i-valve isendaweni evulekile ngokugcwele, indawo yokuvala engemuva ithembeke kakhulu.
8. Idizayini ye-valve stem: Yonke inqubo yokubumba isetshenziselwa ukunquma ubukhulu obuncane ngokwezidingo ezijwayelekile.
9. I-valve stem nut: Ngaphansi kwezimo ezijwayelekile, impahla ye-valve stem nut iyingxube yethusi.Izinto ezifana nensimbi ephezulu ye-nickel cast zingasetshenziswa ngokuya ngezidingo zomsebenzisi.Ukuze uthole umfutho ophezulu kanye nama-valve embulunga amakhulu: ama-rolling bearings aklanyelwe phakathi kwe-stem nut nesiqu, esinganciphisa ngempumelelo i-torque yokuvula i-valve yembulunga ukuze i-valve ivuleke futhi icishwe kalula.
Ngesikhathi sokuvula nokuvala i-valve yeglobu yensimbi eyenziwe ngomgunyathi, ngenxa yokuthi ukungqubuzana phakathi kwe-disc kanye nendawo yokuvala yomzimba we-valve kuncane kunaleyo ye-valve yesango, ayigugi.
I-stroke yokuvula noma yokuvala ye-valve stem imfushane kakhulu, futhi inomsebenzi wokusika othembeke kakhulu, futhi ngenxa yokuthi ukuguqulwa kwembobo yesihlalo se-valve kuhambisana nokushaywa kwe-valve disc, kulungele kakhulu ukulungiswa. wezinga lokugeleza.Ngakho-ke, lolu hlobo lwe-valve lufaneleka kakhulu ukunqunywa noma ukulawulwa nokudonsa.
