Eshabhu laseJinbin, insimbi eyodwa engagqwaliisango lokungenaisiqedile ukucutshungulwa kwayo kokugcina, amasango amaningana ayahlanzwa nge-asidi engaphezulu, kanti elinye isango lamanzi liyahlolwa ngokucindezela kwe-hydrostatic ukuze kuqashwe ngokucophelela ukuthi amasango awavuzi. Wonke la masango enziwe ngensimbi engagqwali engu-304 futhi anosayizi ongu-DN1600. Ivalvu yesango lensimbi yaklanywa nge-flange ukuze ixhunywe kalula kumapayipi.

Lolu hlobo lwesango le-penstock elenziwe ngesandla eline-flange elingaxhunywa kumapayipi lunezinzuzo eziningi

1. Inokwethenjelwa okuphezulu kokuvala. Ubuso be-flange end bufakwe ama-gasket enjoloba, insimbi kanye namanye ama-gasket okuvala, aqiniswe ngokulinganayo ngama-bolts ukuze alingane kahle. Lokhu kungavimbela ngempumelelo ukuvuza kwamanzi, uwoyela, igesi kanye nezinye izinto, futhi kufaneleka kakhulu ezimweni zokusebenza ezinengcindezi ephezulu (PN1.6-10MPa) kanye nezimo zokusebenza ezinezinga lokushisa eliphezulu.

2. Ukufakwa nokugcinwa kulula. Ukuxhumeka kwebholidi akudingi umonakalo emzimbeni wephayiphi. Ngesikhathi sokuhlukaniswa nokuhlanganiswa, amabholidi kuphela okudingeka asuswe ukuze kufakwe isango noma i-gasket esikhundleni salo, okunciphisa kakhulu isikhathi sokulungisa.

3. Inamandla okuxhuma amahle kakhulu. Ama-flange namapayipi ahlanganiswa kakhulu noma akhiwe ndawonye, ​​​​okumelana kakhulu nokudlidliza kanye nomthelela wangaphandle, okuvimbela ukukhululeka ezindaweni zokuxhuma.

4. Inokuguquguquka okunamandla futhi ihambisana nezindinganiso zomhlaba wonke nezasekhaya njenge-GB kanye ne-ANSI. Amasango namapayipi avela kubakhiqizi abahlukene angashintshwa ngokuya ngezincazelo, kuncishiswe izindleko zokukhetha kanye nokuthenga.

I-valve yesango eligobile ingasetshenziswa ezimweni ezahlukahlukene. Emaphrojekthini okuphakelwa kwamanzi kanye nokukhipha amanzi, asetshenziselwa ukulawula amanethiwekhi ezitshalo zamanzi kanye namapayipi omphakathi, ukuvimbela ukuvuza kanye nokwenza kube lula ukugcinwa. Ifanele amapayipi athwala izinto ezibolayo ezifana namafutha aluhlaza kanye nezinyibilikisi zamakhemikhali ensimini ye-petrochemical, futhi ingamelana nomfutho ophezulu.

Isetshenziswa embonini yamandla emipayipini yamanzi anomusi kanye nokupholisa ukuze ibhekane nezimo zokushisa okuphezulu kanye nokucindezela okuphezulu. Emipayipini yegesi kamasipala, kuthenjelwa kuzo izivalo ezithembekile ukuvimbela ukuvuza kwegesi nokuqinisekisa ukuphepha. Ngaphezu kwalokho, ivame ukusetshenziswa ezimweni zokusebenza eziyinkimbinkimbi njenge-metallurgy kanye nokwelashwa kwamanzi ezimbonini, futhi ifanelekela imidiya ekhethekile njengezixazululo ze-asidi kanye ne-alkali kanye ne-slurry.

Uma udinga amasango afanayo noma ezinye izidingo ezenziwe ngokwezifiso, sicela usithinte ngezansi. Abasebenzi abangochwepheshe abavela ku-Jinbin Valves bazokunikeza isevisi yomuntu nomuntu.
