Butterfly valvezvinoreva rudzi rwevharuvhu rine chikamu chinovhara (dhisiki kana butterfly plate) idhisiki, rinotenderera kutenderera shaft yevharuvhu kuti iwane kuvhura nekuvhara.Inonyanya kushandiswa kucheka uye kupuruzira pombi.
The butterfly valve kuvhura nekuvhara chikamu idisc-shaped butterfly plate, iyo inotenderera ichitenderedza axis yayo mumutumbi wevharuvhu kuti iwane chinangwa chekuvhura nekuvhara kana kugadzirisa.Ivhavhavhavhavhavha inowanzoitika isingasviki 90 ″ kubva yakazaruka kusvika yakavharwa zvakazara,
Ivhavhavhavhavha uye hunde reshavishavi hazvina kugona kuzvivharira.Pakumisa ndiro yeshavishavi, chinodzikisira giya rehonye chinofanira kuiswa pahunde yevharuvhu.Kushandiswa kwegonye gear reducer haigoni kuita chete butterfly plate self-locking uye kumisa ndiro ye butterfly pane chero nzvimbo, asiwo inovandudza kushanda kwevhavha.
Iyo indasitiri butterfly valve inoratidzirwa nekupisa kwekushisa kwepamusoro, yakakwirira inoshanda yekumanikidza, yakakura zita dhayamita, uye muviri wevharuvhu wakagadzirwa nekabhoni simbi.
Mhete yekuvharisa yeplate yevharuvhu inoshandisa mhete yesimbi pachinzvimbo chemhete yerabha.Iyo huru tembiricha yeshavishavi vharafu inogadzirwa nesimbi plate welding, uye inonyanya kushandiswa kune flue ducts uye gasi pombi dzepamusoro tembiricha midhiya.
Kuiswa uye kugadziriswa kwevhavhavhavhavha yevhavha kunofanira kubhadhara kune zvinotevera zvinhu: Panguva yekuisa, valve disc inofanira kumira panzvimbo yakavharwa.Nzvimbo yekuvhura inofanirwa kutariswa zvinoenderana nekona yekutenderera kwebhoti butterfly.
Pamavharuvhu eshavishavi ane vharuvhu yekubypass, vharafu yekunzvenga inofanira kuvhurwa isati yavhurwa
Kuiswa kunofanira kuitwa maererano nemirairo yekuisa yemugadziri, uye inorema butterfly valve inofanira kuiswa nenheyo yakasimba.
Zvakanakira butterfly mavharuvhu ndeaya anotevera: zviri nyore uye nekukurumidza kuvhura nekuvhara, kushanda-kuchengetedza, kushomeka kwemvura kuramba, uye inogona kushandiswa kazhinji.
Chimiro chakareruka, diki diki uye uremu huremu.
Madhaka anogona kutakurwa, nekuunganidza kudiki kwemvura pamuromo wepombi.
Pasi pekumanikidzwa kwakaderera, kuvhara kwakanaka kunogona kuwanikwa.
Zvakanaka kugadzirisa kushanda.
Izvo zvisingabatsiri zvevhavhavhavhavha ndezvizvi zvinotevera: huwandu hwekushanda kwekushanda uye kupisa kwekushanda kuduku.
The tightness iri murombo.
Butterfly mavharuvhuinogona kukamurwa kuita offset plate type, vertical plate type, inclined plate type uye lever type zvinoenderana nechimiro.Zvinoenderana nefomu yekuisa chisimbiso, inogona kupatsanurwa mumhando mbiri: yakavharwa mhando uye yakaoma chisimbiso mhando.Iyo yakapfava seal type inowanzo shandisa rubber ring seal, uye hard seal type inowanzo shandisa simbi ring seal.
Zvinoenderana nemhando yekubatanidza, inogona kukamurwa kuita flange yekubatanidza uye wafer yekubatanidza;zvinoenderana neiyo nzira yekufambisa, inogona kukamurwa kuita bhuku, giya rekufambisa, pneumatic, hydraulic uye magetsi.
