Amavalve ovemvane awumndeni wamavalvu ajikelezayo ajikelezayo asetshenziswa kumapayipi, kunezinhlobo eziningi zamavalve ovemvane.Imvamisa, izinhlobo ezahlukahlukene zamavalve emvemvane zihlukaniswa ngokuxhuma, izinto zokwakha,isakhiwo, inqubo yokukhiqiza, njalonjalo.I-ZFA ingomunye wabakhiqizi abadumile be-wafer butterfly valve, abakhiqizi be-butterfly valve be-flange, nabakhiqizi be-lug butterfly valve e-China.
Izinhlobo zamavalve emvemvane ngokuxhuma, ziyizinhlobo ezine.
1.I-valve ye-butterfly ye-wafer
4.I-valve yevemvane ye-U-section
5. Weld butterfly valve
Izinhlobo zamavalvu ovemvane ngezinto zomzimba ze-valve zingaphansi kwezinhlobo ezinhlanu.
1. I-Ductile iron butterfly valve
2. I-Carbon steel butterfly valve
3. I-valve ye-butterfly yensimbi engagqwali
4. I-valve ye-butterfly yensimbi engenasici
5. I-valve ye-butterfly yethusi
Izinhlobo zamavalvu ovemvane ngenqubo yokukhiqiza yemizimba yamavalvu zingaphansi kwezinhlobo ezintathu
1. I-valve ye-butterfly esakazayo
2. Welding butterfly valve
3. Forging butterfly valve
Iyasakaza
Ukushisela
Ukuqamba
Izinhlobo ngokwesakhiwo, zingaphansi kwezinhlobo ezimbili.
1.I-Centerline Butterfly Valve
a.Izinzuzo: Isakhiwo esilula futhi kulula ukusikhiqiza, ukonga;
b.Ukungalungi: Ipuleti le-butterfly kanye nesihlalo se-valve zihlala zisesimweni sokukhipha nokukhuhla, ibanga lokumelana likhulu futhi ukugqokwa kuyashesha.
c.Izicelo: Isetshenziswa kakhulu emikhakheni eminingi efana ne-petroleum, amakhemikhali, i-metallurgy, namandla kagesi.
2.I-Eccentric Butterfly Valve
a.Izinzuzo: Yima izinga lokushisa eliphezulu nokucindezela, Nweba ukuphila kwesihlalo sevalvu
b.Ukungalungi: Kuyabiza futhi kuyinkimbinkimbi ngokwengeziwe ukwenza
c.Izicelo: Isetshenziswa kakhulu ohlelweni lwamapayipi oketshezi okuphakelwa kwamanzi kanye ne-drainage, indle, ukwakhiwa, uphethiloli, amakhemikhali, izindwangu ezilula, ukwenza amaphepha, amandla kagesi, insimbi, amandla, namanye amaphrojekthi.
Ake sihlaziye imigomo efanele kanye nomlando wokuthuthuka we-Centerline butterfly valve kanye ne-eccentric butterfly valve ngokuningiliziwe.
I-Butterfly Valve ephakathi nendawo ibonakala maphakathi ne-axis ye-stem, isikhungo sepuleti uvemvane, kanye nenkaba yomzimba isesimweni esifanayo, njenge-valve ye-centerline evamile.I-valve yevemvane egxilile, imvamisa isuka kusayizi we-DN50 iye ku-DN2200, Ukuvalwa kwevalve uvemvane womugqa ophakathi nendawo ithambile, ngakho iyi-valve enezinga lokushisa eliphansi nengcindezi ephansi.I-ductile iron butterfly valve ingenye yamavalve uvemvane agxilile
Ingcindezi: DN1200, Max pressure PN6;
Izinga lokushisa: Ngokusho izinto zokuvala uphawu, Ngokwesibonelo, NBR, Max lokushisa: 100℃, EPDM, Max lokushisa:150℃;FRM, izinga lokushisa eliphezulu:200℃;I-SBR, izinga lokushisa eliphezulu:100℃;CR, izinga lokushisa eliphezulu:100℃;NR, izinga lokushisa eliphezulu:70℃;HR, izinga lokushisa eliphezulu:100℃;UR, izinga lokushisa eliphezulu:40℃.
Ku-valve ye-butterfly eccentric, ziyizinhlobo ezintathu
a.I-Single Eccentric Butterfly Valve
b.I-valve yevemvane ene-eccentric ephindwe kabili
Umlando we-eccentric butterfly valve type
I-valve uvemvane olulodwa uhlobo lwe-valve uvemvane olukhiqizwe ukuxazulula inkinga yokukhama ipuleti uvemvane kanye nesihlalo se-valve emgqeni ophakathi uvemvane.I-axis ye-stem ichezuka phakathi nendawo ye-valve uvemvane ukuze isiphetho esingezansi se-valve uvemvane singabe sisaba i-eksisi yokuzungezisa, ehlakaza futhi inciphise ukumpintshana kwesikhashana kwezingxenye ezingenhla nezingezansi zepuleti lovemvane kanye nesihlalo sevalvu.
I-double offset butterfly valve ingenye yezinhlobo zamavalvu ovemvane, i-stem axis ivaliwe kokubili enkabeni yepuleti lovemvane naphakathi nendawo yomzimba.Umthelela we-eccentricity kabili wenza i-butterfly plate ikwazi ukuphuma ngokushesha esihlalweni ngemva kokuvulwa kwe-valve, okusiza ekuqedeni ukuminya ngokweqile nokuklwebheka phakathi kwepuleti uvemvane nesihlalo futhi kuthuthukise ukuphila kwesihlalo.Ukunciphisa okuphawulekayo kokukhuhla kwenza kube nokwenzeka ukusebenzisa izihlalo zensimbi kuma-valve e-butterfly eccentric ephindwe kabili, engasetshenziswa ezinhlelweni zokushisa okuphezulu.
I-valve uvemvane oluyi-eccentric kathathu iwuhlobo lwe-valve yovemvane, ngenxa yokuchezuka kwendawo ye-axis ye-stem ngesikhathi esifanayo, okwenza i-axis eyisiyingi ye-butterfly plate sealing surface ichezuke eksisini eyisilinda yomzimba, indawo yokuvala yepuleti uvemvane i-elliptical, Ngakho-ke ukwakheka kwendawo yokubeka uphawu kuyi-asymmetric, uhlangothi olulodwa luthambekele ku-centerline yomzimba, olunye uhlangothi luhambisana ne-centerline yomzimba.Amavalvu ovemvane amathathu ane-eccentric aguqula ngokuyisisekelo indawo evalayo, angabe esaba ukuvalwa kwendawo, kodwa ukuvaleka kwe-torsion, ancike endaweni ethintwayo yesihlalo se-valve ukuze afinyelele umphumela wokuvala, ukuxazulula inkinga yokuvuza kweziro kwesihlalo se-valve yensimbi.Njengoba ukucindezela kwendawo yokuxhumana nokucindezela okuphakathi kuyalingana, kuphinde kuxazulule inkinga yokucindezela okukhulu nokushisa okuphezulu, futhi i-valve butterfly isetshenziswa kabanzi.
