Namuhla, i-DN1200 enosayiziivalvu yokuhlola egobile enesando sobunzimae-Jinbin workshop isiqede yonke inqubo yokukhiqiza futhi iyaqhubeka nokusebenza kokugcina kokupakisha, okuzothunyelwa kumakhasimende. Ukuqedwa ngempumelelo kwala manziivalvu yokuhlolaakubonisi nje kuphela amasu okukhiqiza amahle kakhulu e-workshop, kodwa futhi kugqamisa inani elibalulekile lama-valve okuhlola okuvala kancane anamandla amancane amelana nokumelana nogesi emkhakheni wokulawula uketshezi lwezimboni.

Amavalvu okuhlola amakhulu, anomklamo wawo oyingqayizivele, anezici eziningana eziphawulekayo. Okokuqala, amandla okugeleza aqinile yinzuzo yawo eyinhloko. Ivalvu yokuhlola ene-DN1200 flanged ingahlangabezana nesidingo sokuthuthwa koketshezi olukhulu, ngokulahlekelwa okuncane kwengcindezi ngesikhathi senqubo yokuthutha, okungathuthukisa ngempumelelo ukusebenza kahle kwesistimu. Okwesibili, inokuqina okuphezulu kwesakhiwo. Yenziwe ngezinto ze-alloy ezinamandla aphezulu, umzimba wevalvu unobukhulu obufanayo bodonga futhi ungamelana nezimo zokusebenza ezinzima njengokucindezela okuphezulu kanye nokushisa okuphezulu. Impilo yayo yesevisi idlula kakhulu eyevalvu yokuhlola i-butterfly. Ngaphezu kwalokho, amavalvu okuhlola amakhulu anokusebenza okuhle kakhulu kokuvala. Ngokucutshungulwa okunembile kwendawo yokuvala kanye ne-valve core, anganciphisa ukugeleza kwe-medium ngezinga elikhulu futhi aqinisekise ukusebenza okuphephile kwesistimu.

Njengesigaba sezinga eliphezulu phakathi kwevalvu yensimbi enkulu ephothiwe, ivalvu yokuhlola ukuvala kancane ephikiswayo enokumelana okuncane inezinhlelo zokusebenza ezingenakuguqulwa emikhakheni eminingi ebalulekile. Emaphrojekthini okuphakelwa kwamanzi emadolobheni, ifakwe kabanzi kumapayipi amakhulu okudlulisa amanzi ezitshalweni zamanzi. Ayikwazi nje ukuhlangabezana nesidingo esikhulu samanzi ngesikhathi samahora aphezulu kodwa futhi ivimbela amanzi ukuthi angene emsebenzini wayo wokuvala kancane, ivikele amapayipi kanye nemishini yokupompa. Ohlelweni lwamanzi olujikelezayo lwezitshalo zamandla okushisa, leli valve elingabuyi lingalawula ngokunembile indlela yokulethwa kwamanzi okupholisa, livimbele ukugeleza kwamanzi emuva ngesikhathi sokuvala, futhi liqinisekise ukuvalwa okuphephile kwamayunithi akhiqizayo. Ezitshalweni zokwelashwa kwamanzi okungcola ezinkulu, umklamo omelana nokugqwala ungavumelana nokwakheka okuyinkimbinkimbi kwemidiya yokungcola. Okwamanje, umsebenzi wokuvala kancane unganciphisa ukudlidliza kwamapayipi futhi wehlise izindleko zokulungisa imishini.

Uma unesidingo sokwenza ngokwezifiso ama-valve amakhulu, sicela usithinte ngezansi. Uzothola impendulo zingakapheli amahora angama-24 futhi sizokwenza ngokwezifiso ikhambi elifanele wena mathupha.
