I-FUO1 BV1UDF 2L (Uvalued iivelufa zebhabhathane)
Yazisa
I-U-uhlobo esisangqa ibhabhathane vana yamkela phezulu imvelaphi inyuselwa khona, nto leyo kunciphisa iibholiti kokuxhuma umzimba vana ngokwalo phantsi koxinzelelo oluphezulu nobubanzi enkulu, kwandisa ukuthembeka ivelufa kwaye oyisa ifuthe ubunzima inkqubo kwi eqhelekileyo ukusebenza kwevalve.
Ububanzi besicelo
Uhlobo lwe-U-flange butterfly valve lusetyenziswa kakhulu kwimizi-mveliso yamachiza amalahle, imveliso ye-petrochemical, irabha, ukwenza iphepha, amayeza kunye neminye imibhobho njengombane we-shunt confluence okanye isixhobo esitshintshayo sokuhamba.
Ipleyiti yebhabhathane yesivalo sebhabhathane ifakelwe kwicala lobubanzi bombhobho. Kwisitampu se-cylindrical somzimba wevelufa webhabhathane, isitya sebhabhathane esenziwe nge-disc sijikeleza i-axis, kwaye i-angle yokujikeleza iphakathi kwe-0 ° kunye ne-90 ° kwaye xa ujikelezo lufikelela kuma-90 ° isitya sevalve sivulekile ngokupheleleyo.
Ivelufa yebhabhathane ilula kulwakhiwo, ngobukhulu obuncinci kunye nobunzima bokukhanya, kwaye inamalungu ambalwa kuphela. Ngapha koko, ivalve ingavulwa kwaye ivalwe ngokukhawuleza ngama-90 ° ngokujikeleza, ekulula ukusebenza. Kwangelo xesha, ivalve ineempawu ezifanelekileyo zokulawula ulwelo. Xa ivalve ibhabhathane ivalve ikwindawo evulekileyo ngokupheleleyo, ubukhulu bepleyiti yamabhabhathane kuphela kokuxhathisa xa iphakathi lihamba emzimbeni wevalve, ngenxa yoko ukwehla koxinzelelo okuveliswe yivelufa kuncinci kakhulu, ke kuneempawu ezifanelekileyo zokuhamba kokuhamba. Ibhabhathane ivelufa itywina elastic nesinyithi I-valve yokutywina e-elastic, iringi yokutywina inokufakwa emzimbeni wevalve okanye iqhotyoshelwe kumda wepleyiti yebhabhathane.
Ivalve enetywina lesinyithi inobomi benkonzo ende kunaleyo itywiniweyo, kodwa kunzima ukuyitywina ngokupheleleyo. Isitywina sentsimbi sinokuziqhelanisa nobushushu obuphezulu bokusebenza, ngelixa itywina le-elastic linomda wobushushu.
Ukuba kufuneka ibhabhathane ivelufa ukuze isetyenziswe njengokulawula ukuhamba, eyona nto iphambili kukukhetha ubungakanani ochanekileyo kunye nohlobo lwevalve. Umgaqo wesakhiwo wevelufa yamabhabhathane ulungele ngokukodwa ukwenza ivelufa enobubanzi obukhulu. Ivelufa yebhabhathane ayisebenzisi kuphela ipetroleum, igesi, ishishini lamachiza, unyango lwamanzi kunye namanye amashishini ngokubanzi, kodwa ikwasetyenziswa nakwinkqubo yokupholisa amanzi kwisikhululo samandla eshushu.
