FUO1 BV1UDF 2L (U flanged uvemvane valve)
Yethula
I-U-type flange butterfly valve isebenzisa isakhiwo esifakwe phezulu, esinciphisa amabhawodi wokuxhuma womzimba we-valve uqobo ngaphansi kwesimo sengcindezi ephezulu nobubanzi obukhulu, kuthuthukisa ukuthembeka kwe-valve futhi kunqobe ithonya lesisindo sohlelo kokujwayelekile ukusebenza kwe-valve.
Ububanzi besicelo
I-U-type flange butterfly valve isetshenziswa kakhulu embonini yamakhemikhali yamalahle, imboni ye-petrochemical, irabha, ukwenziwa kwephepha, ezemithi kanye namanye amapayipi njengendlela yokusebenzisa i-shunt confluence noma i-flow switching device.
Ipuleti levemvane levevemvane lifakwe kusiyingi sephayiphi. Kumzila wesilinda womzimba womvemvane wevemvane, ipuleti levemvane elimise okwe-disc lizungeza i-eksisi, futhi i-engeli yokujikeleza iphakathi kuka-0 ° no-90 ° futhi lapho ukuzungeza kufinyelela kuma-90 ipuleti le-valve livuleke ngokuphelele.
I-butterfly valve yakhiwe ngesakhiwo, ngosayizi omncane nokukhanya kwesisindo, futhi inezingxenye ezimbalwa kuphela. Ngaphezu kwalokho, i-valve ingavulwa futhi ivalwe ngokushesha ngokuzungezisa okungu-90 ° kuphela, okulula ukusebenza. Ngesikhathi esifanayo, i-valve inezici ezinhle zokulawula uketshezi. Lapho i-flange butterfly valve isendaweni evulekile ngokuphelele, ubukhulu bepuleti levemvane ukuphela kokumelana lapho okuphakathi kugeleza emzimbeni we-valve, ngakho ukwehla kwengcindezi okwenziwe yi-valve kuncane kakhulu, ngakho-ke inezici ezinhle zokulawula ukugeleza. Butterfly valve has nokunwebeka seal nensimbi seal. I-elastic yokuvala uphawu, indandatho yokufaka uphawu ingafakwa emzimbeni we-valve noma inamathele emaphethelweni epuleti levemvane.
I-valve enophawu lwensimbi inokuphila okude kunaleyo ene-elastic seal, kepha kunzima ukuyivala ngokuphelele. Uphawu lwensimbi lungakwazi ukuzivumelanisa nokushisa okuphezulu kokusebenza, kanti uphawu lwelastiki lunomkhawulo wokushisa.
Uma kudingeka ivelufa levemvane ukuze lisetshenziswe njengokulawulwa kokugeleza, into esemqoka ukukhetha usayizi nohlobo olufanele lwe-valve. Isimiso sesakhiwo sevemvane levemvane silungele ngokukhethekile ukwenza i-valve enkulu yobubanzi. I-butterfly valve ayigcini nje ngokusetshenziswa kabanzi ku-petroleum, igesi, imboni yamakhemikhali, ukwelashwa kwamanzi nezinye izimboni ezijwayelekile, kodwa futhi isetshenziselwa uhlelo lwamanzi okupholisa wesiteshi samandla esishisayo.
