Uhlobo lomkhiqizo we-valve

I-valve iyisici sokulawula ohlelweni lokudlulisa uketshezi, olunomsebenzi wokunqamula, ukulawula, ukuphambukisa, ukuvimbela ukugeleza okubuyela emuva, ukuqiniswa, ukuphambukisa noma ukuchichima kanye nokukhulula ingcindezi.Amavalvu asetshenziswa ezinhlelweni zokulawula uketshezi, kusukela kumavalvu alula ukuvala kuya kumavalvu ahlukahlukene asetshenziswa ezinhlelweni zokulawula ezizenzakalelayo eziyinkimbinkimbi kakhulu, anezinhlobonhlobo zezinhlobonhlobo kanye nokucaciswa.
Amasistimu amapayipi ahlukene asebenzisa ama-valve emishini anezinto ezihlukene, izakhiwo, imisebenzi, nezindlela zokuxhuma.Ngakho-ke, kukhona amagatsha asebenzayo kanye nama-trickles ngaphakathi kwama-valve emishini, anezinzuzo zawo, ukungalungi kanye nezinkambu zokufaka isicelo.Ochwepheshe badinga ukukhetha amavalvu emishini ngokwezidingo zangempela zohlelo lwamapayipi., Ukuqinisekisa ukusebenza okuzinzile kwesistimu yamapayipi.

I-globe valve:
I-valve yokuvala inesakhiwo esilula.Kuyinto elula kakhulu futhi elula kungakhathaliseki ukuthi ukuhlanganisa, ukusetshenziswa, ukusebenza nokugcinwa, ukuqaqa ohlelweni lwamapayipi, noma ukuhlolwa kokukhiqizwa kanye nekhwalithi efektri;umphumela wokuvala muhle, nempilo yesevisi ohlelweni lwamapayipi yinde Lokhu kungenxa yokuthi idiski nendawo yokuvala yevalvu yokuvala imile ngokuqhathaniswa, futhi akukho ukuguga okubangelwa ukushelela;isikhathi esiningi futhi sisebenza kanzima, lokhu kungenxa yokuthi i-disc stroke ifushane futhi i-torque inkulu, futhi kuthatha amandla amaningi kanye nesikhathi sokuvula i-valve yokuvala;Ukumelana noketshezi kukhulu, ngoba ukudlula kwangaphakathi kwe-valve yokuvala kuhlukumeza kakhulu lapho kubhekene noketshezi, futhi uketshezi ludinga ukudla amandla amaningi ngesikhathi sokudlulisa i-valve;isiqondiso sokugeleza kwe-fluid sisodwa, futhi ama-valve e-valve avaliwe okwamanje emakethe angakwazi ukusekela isiqondiso esisodwa Hambisa, ungasekeli izinguquko zendlela ezimbili nangaphezulu.

Ivaluvu yesango:
Ukuvulwa nokuvalwa kwe-valve yesango kuqedwa yi-nut ephezulu nesango.Lapho ivala, incike ekucindezelweni okuphakathi kwangaphakathi ukuze ibone ukucindezelwa kwesango nesihlalo se-valve.Lapho ivula, incike kumantongomane ukuze ibone ukuphakanyiswa kwesango.Amavalvu esango anokuvalwa kahle nokusebenza kahle, futhi ngokuvamile asetshenziswa ezinhlelweni zamapayipi ezinobubanzi obungaphezu kuka-50 mm.Ukucindezela kusetshenziselwa ukuqaphela ukucindezelwa kwesango kanye nesihlalo se-valve, futhi i-nut isetshenziselwa ukuqaphela ukuphakanyiswa kwesango lapho livuliwe.Amavalvu esango anophawu oluhle nokusebenza kahle kokusika, futhi ngokuvamile asetshenziswa ezinhlelweni zamapayipi ezinobubanzi obungaphezu kuka-50 ㎜
Phakathi.Umsebenzi we-throttling usetshenziswa kakhulu kumapayipi kawoyela, igesi yemvelo, kanye namanzi

I-valve yebhola:
I-valve yebhola inokusebenza kokulungisa isiqondiso sokugeleza koketshezi kanye nezinga lokugeleza, futhi inokusebenza kokuvala okuphezulu.Indandatho yokuvala ngokuvamile yenziwe nge-PTFE njengento eyinhloko, ekwazi ukumelana nokugqwala ngezinga elithile, kodwa ukumelana nokushisa okuphezulu akuphakeme, kudlula izinga lokushisa elifanele Ukuguga kuyashesha kakhulu, futhi kuzothinta umphumela wokuvala we-valve yebhola.Ngakho-ke, i-valve yebhola ifaneleka kakhulu ukulungiswa kwezindawo ezimbili, ukumelana noketshezi oluncane, izidingo eziphakeme zokuqina, kanye nemingcele yokushisa ephezulu ngaphakathi kwezinga elithile lesistimu yamapayipi.Indawo yonke iphansi, futhi ifanele amagatsha esistimu amaningi kanye nezidingo zokusebenza ezinemininingwane eyengeziwe.Ukufakwa kwamapayipi aphakeme akudingekile kumapayipi aqondile, asikho isidingo sokugeleza koketshezi, umthamo wokugeleza, futhi izinga lokushisa loketshezi liphezulu kakhulu ohlelweni lwamapayipi, okuzonyusa ukucindezela kwezindleko.

I-Butterfly valve:
I-valve uvemvane yamukela umklamo ohlelekile uwonke, ngakho ukumelana noketshezi kuncane uma kusetshenziswe ohlelweni lwamapayipi.I-valve yovemvane isebenzisa isakhiwo senduku ukuze isebenze ivalvu.I-valve ivaliwe futhi ivuliwe hhayi ngokuphakamisa, kodwa ngokujikeleza, ngakho izinga lokugqoka liphansi futhi impilo yesevisi yinde.Ama-valve ovemvane avame ukusetshenziswa ezinhlelweni zamapayipi ukufudumeza, igesi, amanzi, uwoyela, i-asidi kanye nokuthutha uketshezi lwe-alkali.Angamavalvu emishini avaleka kakhulu, impilo ende yesevisi, nokuvuza okuncane.
