Ngaba uyalwazi ulwahlulo oluqhelekileyo lweevalvu zebhabhathane zombane?

Iivalvu zebhabhathane zombaneluhlobo lwevalve yombane kunye nevalve yokulawula yombane. Iindlela zokudibanisa eziphambili zombaneiivalve butterflyzezi: uhlobo lwe-flange kunye nodidi lwe-wafer; iindlela eziphambili zokutywina zeiivalve zebhabhathane zombanezezi: ukutywinwa kwerabha kunye nokutywinwa kwesinyithi.

Umbaneivelufa butterflyilawula ukuvuleka nokuvalwa kwevalve yebhabhathane ngemiqondiso yamandla. Le mveliso ingasetyenziselwa i-valve yokuvala, i-valve yokulawula kunye ne-valve yokukhangela kwiinkqubo zemibhobho. Ixhotyiswe ngesixhobo sokulawula ngesandla. Kwimeko yokusilela kwamandla, inokusebenza okwethutyana ngesandla ukunqanda ukuchaphazela ukusetyenziswa kwayo.

Ukuhlelwa ngokwefomu yolwakhiwo

(1) Itywina eliphakathi

Ungatshatangaeccentric itywina yombane butterfly valve.

(3)Ivalve yebhabhathane etywiniweyo ephindwe kabini.

(4) Ivalve yebhabhathane yombane ene-offset ezintathu etywiniweyo.

2. Ukuhlelwa ngokutywinwa kwezinto ezingaphezulu

(1) Isibini sokutywina esithambileyo senziwe ngezinto ezithambileyo ezingezizo ezentsimbi ngokuchasene nemathiriyeli ethambileyo engeyiyo eyentsimbi. Isibini sokutywina senziwe ngezinto eziqinileyo zesinyithi ngokuchasene nemathiriyeli ethambileyo engeyiyo eyentsimbi.

(2) Ivalve yebhabhathane yentsimbi yombane eqinileyo. Isibini sokutywina senziwe ngezinto eziqinileyo zetsimbi ngokuchasene nezinto eziqinileyo zetsimbi.

3. Ukuhlelwa ngokutywinwa kwefom

(1) Ukutywinwa ngenkani: Ivalve yebhabhathane yombane etywiniweyo. Uxinzelelo oluthile lokutywina lwenziwa yipleyiti yevalve ekhama isihlalo sevalve xa ivalve yombane ivaliwe, kunye nokunwebeka kwesitulo sevalvu okanye ipleyiti yevalvu. Ivalve yebhabhathane yombane yokutywina itorque yangaphandle, uxinzelelo olukhethekileyo lokutywina luveliswa yitorque esetyenziswa kwivalufa yevalve.

(2) Ivalve yebhabhathane yombane etywinwa ngoxinzelelo: Uxinzelelo oluthile lokutywina lwenziwa ngokucinezela into etywiniweyo yokutywina kwisitulo sevalve okanye kwipleyiti yevalvu.

(3) Ukutywina okuzenzekelayo kwevalve yebhabhathane yombane: Uxinzelelo oluthile lokutywina lwenziwa ngokuzenzekelayo luxinzelelo oluphakathi.
