Ukufaneleka kwezinkambiso zezinkambiso

Ukufaneleka kwezinkomba zeglobe.

A globe valve is a valve in which the closing member (valve flap) moves along the centerline of the valve seat. According to this form of movement of the valve flap, the change of the valve seat orifice is proportional to the valve flap stroke. Since the stem opening or closing stroke of this type of valve is relatively short and has a very reliable shut-off function, and since the change in the seat orifice is proportional to the travel of the valve flap, it is very suitable for regulating the flow rate. Therefore, this type of valve is very suitable for cutting off or regulating and throttling.

Isikhala se-Globe valve flap ekhishwe kusukela ekhishwe kusukela ekufungweni, isiqandisi sakhe nokuhlushwa kwesiqandisi sakhe asikwazi ukudlala ngokuphelele, ngakho isiqandisi sakhe sokuhlushwa kuyinto enhle kakhulu, okungenamkhawulo kuyinto ukuthi isiqandisi sakhe singathathwa phakathi kwamaparti ekusakazweni. Kodwa, uma isikala se-valve flap sibonakala njengesibhakela esisitayela noma isibhakela se-porcelain, le nto izosulwa. Ngakho konke okuningi kwesikala se-valve seat kanye ne-valve flap globe valve kuyinto enjalo okungenamkhawulo ukwenza okuningi noma ukulungiswa, futhi ekulungiseni noma ekulungiseni isiqandisi sokuhlusha asikwazi ukuthatha isivalo sonke se-valve ekusakazweni, okuyinto enhle kakhulu ekwakhiweni kwe-valve kanye ne-pipeline.

Ukuphambuka kwamanzi okulula kwezivalo zeglobe kungaba kuncane kunazo zonke izinhlobo zezivalo ngenxa yokuthi kubalulekile ukubuka kwamanzi ngaphakathi kwezivalo ezifana nazo. Kodwa, le nto iyatholakala ukuthi iyatholakala ngokwengqondo kwiqembu lezivalo kanye nokwenza kwesitayela somkhumbi kusukela kwiinkanuko zezivalo kwi-inlet kanye ne-outlet. Ngokwesibonelo, uma isitayela somkhumbi sigqithisa futhi sibeka phakathi kweminyaka engu-1, isitayela sokuphambuka sisebenzela kahle kakhulu ekwenzeni izinto ezidinga ukugqamisa ngokweqile. Isitayela somkhumbi sicacisa kwiinkqubo zeziflow zezinto eziningi. Kwenziwe ukwenza ukwazi ukwakha izinto eziningi zezivalo zeglobe ezifanele kwenziwe ukwakha izinto eziningi zezivalo zeglobe ezifanele kwenziwe ukwakha izinto eziningi zezivalo zeglobe ezifanele kwenziwe ukwakha izinto eziningi zezivalo zeglobe ezifanele kwenziwe ukwakha izinto eziningi zezivalo zeglobe ezifanele kwenziwe ukwakha izinto eziningi zezivalo zeglobe ezifanele kwenziwe ukwakha izinto eziningi zezivalo zeglobe ezifanele kwenziwe ukwakha izinto eziningi zezivalo zeglobe ezifanele kwenziwe ukwakha izinto eziningi zezivalo zeglobe ezifanele kwenziwe ukwakha izinto eziningi zezivalo zeglobe ezifanele.

Izinkinga zokusetshenziswa kwamaglobhu valve kuyinto enkulu kakhulu, kodwa ngenxa yokuthi isikhwama sokuvula nokufaka kubalulekile kakhulu, isimo sokwenza kuyinto eside, kuhambisana nomzila okuyisikhombisa, kubonakala ukuthi isikhombisa esisodwa kufinyelela ekulimazweni okuphansi kwe-250mm, kune-400mm, kodwa ukhetho lwezindlela yokungena nokuhamba kuyadinga ukucabanga okunye. Kusukela kubalulekile ukuthi izinga lokucuthwa kwe-150mm phezulu, amamedya amaningi kusukela ekubhujisweni kwesikhwama sokuphansi kuya kubhujiswa ekubhujisweni kwesikhwama sokuphansi phezulu. Lokhu kuyenzeka ukuze kwenzeke izinga lokucuthwa kwesikhwama. Ukuze kwenzeke ukucabangela isikhwama sokuvula noma sokucisha, kubonakala ukuthi izinkomba ezingu-200mm phezulu zisetshenziswa ekubhujisweni noma ekubhujisweni kwesikhwama sokuphansi.
