Yintoni umsebenzi wevalve yeglowubhu?
2019-10-10
Iivalvu zeglowubhu zisetyenziselwa ukuvala ukuhamba kwemidiya. Iivalvu zeglowubhu zifanelekile kumathuba afuna ukuvulwa rhoqo. Ngokuqhelekileyo zisetyenziselwa ukuveliswa kweekhemikhali. Iindawo zokutywina zeevalvu zeglowubhu ziidiski kunye nezihlalo. Ukuze uvale iivalve zeglobhu ngokuqinileyo, iindawo zokukhwelana kweediski kunye nezihlalo kufuneka zibe phantsi okanye zifakwe i-gasketed, kunye nezixhobo ezinganyangekiyo kunye ne-corrosion-resistant-resistant ezifana ne-bronze kunye nensimbi engenasici inokufakwa kwiindawo zokutywinwa. Idiski kunye nesiqu sevalve yeglowubhu ziqhagamshelwe ngokushukumayo ukuququzelela idiski kunye nesiqu ukuba zilingane ngokusondeleyo. Ukunyuka kunye nokuwa kwe-disc yevalve yeglobhu ngokuqhelekileyo ilawulwa sisikhondo. Inxalenye ephezulu yesiqu sevalve yeglowubhu livili lesandla, kwaye indawo ephakathi ngumsonto kunye necandelo lokupakisha lokutywina. Umsebenzi wokupakisha kukuthintela ukuvuza kwendawo ephakathi ngaphakathi kumzimba wevalvu ecaleni kwesiqu. Umsebenzi ophambili wevalve yeglowubhu kumbhobho wekhemikhali kukunqumla okanye ukudibanisa ulwelo. Umyinge olawulayo wokuqukuqela kwevalve yeglowubhu ungcono kunalowo wevalve yesango. Kodwa ivalve yeglowubhu ayinakusetyenziswa ukulawula uxinzelelo kunye nokuhamba ixesha elide. Kungenjalo, umphezulu wokutywina wevalve yeglowubhu unokukhukuliseka ngokuphakathi kwaye ukusebenza kokutywina kunokutshatyalaliswa. Iivalvu zeglowubhu zingasetyenziswa emanzini, umphunga, umoya ocuthekileyo kunye neminye imibhobho, kodwa ayifanelekanga kwimibhobho ephakathi ene-viscosity ephezulu, ukupheka lula kunye nemvula, ukunqanda ukonakalisa umphezulu wokutywina. Umgaqo osebenzayo wevalve yeglowubhu kukuba idiski yevalve yeglowubhu ihamba ngokuthe nkqo ecaleni komgca osembindini wesihlalo, kwaye ixhomekeke ekujikelezweni komsonto wesiqu, ukuze indawo yokutywina yediski yevalve yeglowubhu kunye nomphezulu wokutywina wevalve yeglowubhu. izihlalo zibambene ngokusondeleyo, ngaloo ndlela zinqumle ukuhamba kwe medium. Izinto eziluncedo kunye nezingeloncedo kwiivalvu zeglowubhu Izinto eziluncedo zeGlobe Valve Globe valve ine-stroke encinci yokusebenza kunye nexesha elifutshane lokuvula kunye nokuvala. Ivalve yeglowubhu inepropathi elungileyo yokutywina, ukungqubana okuncinci phakathi komphezulu wokutywina kunye nobomi benkonzo ende. Ivalve yeglowubhu inomsebenzi olungileyo wokulawula. Ukungalungi kwevalve yeglowubhu Ubude bofakelo lwevalve yeglowubhu inkulu, kwaye ukuxhathisa kokuhamba okuphakathi kukhulu. Iivalvu zeglowubhu zintsonkothile ngokwesakhiwo kwaye kunzima ukuzivelisa nokuzigcina. Ukuhamba kwevalve yeglowubhu kudlula kwisitulo sevalve ukusuka ezantsi ukuya phezulu, enokumelana okukhulu kwaye ifuna amandla amakhulu xa uvula kwaye uvala. Iivalvu zeglowubhu azifanelekanga ukuba ziphakathi ezinamasuntswana, i-viscosity ephezulu kunye nokupheka okulula. Iivalvu zeglowubhu zisoloko zisetyenziswa kwimibhobho efuna ukuvulwa ngokupheleleyo nokuvala ngokupheleleyo, kwaye imibhobho yomphunga isetyenziswa kakhulu. Uqhagamshelo phakathi kwevalve yeglowubhu kunye nombhobho, nokuba ujijelwe okanye ujikelezwe.
