Ukuqonda iiFlanged Ball Valves: iiFlanges kunye neeBall Valves
Ukuze siyiqonde ngokupheleleyo ivalvu yebhola ejijekileyo, makhe sihlalutye izinto zayo ezimbini ezisisiseko:
Yintoni iValve yeBhola:
Intliziyo yayo ixhomekeke kumgangathoIvalvu yeBholaumgaqo. Ibhola engqukuva enembobo (umngxuma) embindini wayo ijikeleza iidigri ezingama-90 ngaphakathi komzimba wevalvu. Xa imbobo ihambelana nombhobho, ukuhamba kwamanzi akuthintelwa (kuvuliwe). Xa ijikeleziswa ngokuthe nkqo, ibhola eqinileyo ivimba ukuhamba kwamanzi ngokupheleleyo (ivaliwe). Olu yilo lubonelela ngokusebenza ngokukhawuleza, amandla okuvala agqwesileyo, kunye nokunciphisa ukuhamba kwamanzi xa ivuliwe ngokupheleleyo (ingakumbi kwiidizayini zezibuko ezipheleleyo).
Yintoni iFlange End Connection:
I-flange yevalvu yindlela yokwakheka apho ivalvu iqhagamshelwe kumbhobho kusetyenziswa indlela yoqhagamshelo lweflange. Yinto eqhelekileyo yoqhagamshelo olususwayo kwiinkqubo zemibhobho yemizi-mveliso.
Inkcazo engundoqo:
I-flange yevalvu sisakhiwo esimile okweflange esenziwe kuzo zombini iziphelo okanye indawo yokungena kunye nendawo yokuphuma yomzimba wevalvu. Ibotshelelwa kwiflange yepayipi kusetyenziswa iibholiti kunye neegaskets ukuze kufezekiswe ukutywinwa kunye nokuhamba kwamanzi.
Ikwicandelo "leevalvu eziqhagamshelwe kwiflange," igxininisa indlela yokudibanisa endaweni yohlobo lwevalvu (umz., iivalvu zebhabhathane, iivalvu zebhola, iivalvu zesango, njl.njl., zonke zinokujikwa).
Iiflanges zithe tyaba, zifana neediski kunye nothotho lwemingxuma yebholthi ebholiweyo ejikeleze umjikelezo wazo. Kwivalvu yebhola eflangekileyo, ezi zifakwa ngokudibeneyo okanye zifakwe kwisiphelo somzimba wevalvu. Ivalvu ifakwa ngokufaka i-gasket phakathi kweeflanges zayo kunye neeflanges zepayipi, emva koko kuqiniswe iibholthi ezijikeleze umjikelezo. Oku kudala ijoyinti eqinileyo, engaxinzelelekiyo enokususwa ngokulula ukuze kugcinwe okanye kutshintshwe iivalvu ngaphandle kokusika umbhobho.
