cast steel metal esihlalweni butterfly valve

Ama-valve okuhlola noma ama-valve endlela eyodwa aklanyelwe ukumisa ukubuyela emuva futhi ekugcineni avikele amaphampu nama-compressor.Atholakala ngezitayela nobukhulu obuhlukahlukene, kusukela ku-1/8" kuya kusayizi omkhulu kakhulu ongase udinge.Ama-valve okuhlola asetshenziswa ezimbonini eziningi. ezinhlobonhlobo zezicelo, kusukela emanzini kamasipala kuya ezimayini kanye negesi yemvelo.Izinhlobo ezintathu ezivame kakhulu ama-valve okuhlola ama-swing, ama-valve okuhlola iminyango emibili, nama-valve okuhlola ukugeleza kwe-spring-assisted axial esetshenziswa namuhla futhi iwumklamo ogcwele wembobo, okusho ukuthi idiski ayikho kumfudlana wokugeleza lapho ivuleke ngokugcwele.Lolu hlobo lwevalvu yokuhlola lulungele izinhlelo zokusebenza ezinamaphesenti aphezulu okuqinile kanye nenani eliphansi lemijikelezo yokuvula/yokuvala.Ama-valve okuhlola i-Swing avale kancane kancane ngenxa yebanga lokuhamba le-disc.Lokhu kubangela ukugeleza kokugcina okuhlanekezela ukusunduza i-valve disc ivaleke, okubangela ukukhuphuka kokucindezela okukhulu okubangela isando samanzi.Isando samanzi siwukushaqeka kokucindezela lapho uketshezi olunyakazayo luphoqeleka ukuba lume noma lushintshe ngokuzumayo. isiqondiso, ukudala igagasi lokucindezela epayipini.Amaza okucindezela anjalo angabangela izinkinga ezinkulu kusukela emsindweni nokudlidliza kuya kumapayipi awile. Le valve ifana nevalve yokuhlola ukujika futhi ingcono kancane ekuvaleni ngoba iziphethu zekhoyili zisiza izicabha ezimbili ezinama-cantilever ukuba zivale ngokushesha. Kuvele ukuthi lokhu akuyona into engcono kakhulu uma ubhekene nesando samanzi, nakuba isebenza kangcono kunama-valve okuhlola ama-swing. .Ngokuvamile, le valve ibhekwa njenge-valve yempahla engekho eshalofini enezinketho ezincane zokwenza ngokwezifiso. Lawa mavalvu ageleza ngokugcwele aqukethe i-stem-disc eqondiswa maphakathi nendawo kanye nesiphethu sokucindezela.Lokhu kusho ukuthi idiski ihlala kumfudlana wokugeleza.Imidiya igeleza izungeza, ngaphandle kosizo olwenziwa ngesandla noma oluzenzakalelayo.Lapho iphampu isebenza, ivalvu ivula.Lapho iphampu ivaliwe, i-valve ivala kancane ngaphambi kokuba ukugeleza kwamanzi kubuyele emuva ngenxa yamandla okucindezela asentwasahlobo asebenza ku-disc, aqeda ngokuphelele isando samanzi. Izimfuneko eziningi zamavalvu okuhlola zicabangela kuphela usayizi womugqa kanye nesilinganiso sokucindezela, njengoba ingcindezi ephakathi nendawo namazinga okugeleza angashintsha kakhulu lapho amadizayini amapayipi enziwa abe mkhulu ngezinkinga zesikhathi esizayo noma abe ngaphansi ngenxa yokuntuleka noma ulwazi olungalungile .Lena akuyona njalo indlela engcono kakhulu uma unquma ukuthi iyiphi uhlobo lwe-valve okufanele lusetshenziswe ohlelweni.Ezinye izici okufanele zicatshangelwe ingcindezi yokusebenza, izinga lokugeleza, amandla adonsela phansi athile kanye nezinga lokushisa le-medium.Ukuhlaziywa komklamo wesistimu kunconywa kakhulu.Kudingeka ukuqonda izimbangela nezimbangela zokuhluleka kwe-valve .Ukwehluleka okuvame kakhulu kungenxa yokuguga ngokweqile ezingxenyeni zangaphakathi ze-valve.Ukuguga ngaphambi kwesikhathi kweziphethu, ama-disc neziqu ezingaqinile ngesikhathi sokusebenza.Ukuxoxisana kungenzeka lapho i-disc ingazinzile ngenxa yokungagelezi okwanele ukuze uyibambe ivuleke ngokugcwele. isikhundla. Ukulinganisa i-valve yokushayela emaphakathi akunzima.Ngaphezu kosayizi wepayipi odingekayo, isilinganiso sokucindezela kanye nohlobo lwe-valve (i-flange, i-wafer, njll.), umsebenzisi udinga ukucindezela kwangempela kokusebenza, izinga lokugeleza, uhlobo lwemidiya, izinga lokushisa kanye namandla adonsela phansi athile. wemidiya.Kungase kube lula njengokwakha i-valve ngesiphethu esilula ukuze uvule ngokugcwele i-valve.Ukuletha i-valve endaweni evuleke ngokugcwele, kungase kudingeke umkhawulo wokuphakamisa ukunciphisa ukuhamba kwediski.Lapho i-valve ivuleke ngo-100%, ihlala izinzile ekuhambeni futhi inciphisa ukuguga nokwehluleka ngaphambi kwesikhathi ngokususa imiphumela yokuxoxa.Kubalulekile ukukhumbula ukuthi lawa mavalvu enzelwe amanani okugeleza angempela, hhayi usayizi womugqa.I-valve enosayizi ofanele izoba indawo evuleke ngokuphelele noma evalwe ngokugcwele. Kuye ngomthelela wemali engenayo elahlekile, amaholo, kanye nezindleko zokushintsha i-valve, izindleko zokushintsha i-valve zingaba phezulu kakhulu. ?Uma i-valve yosayizi owodwa ibiza ngokuphindwe kahlanu, kodwa iphindwe kahlanu kunesikhathi sesevisi, cabanga ukuthi lokhu kuyithinta kanjani ibhalansi yezimali, ucabangela izindleko zokuyilungisa kanye nokulahlekelwa kokukhiqiza. Nakuba ezinye izinhlelo zokusebenza zidinga ama-valve okuhlola iminyango emibili kanye ne-swing ukuze asebenze kahle futhi ayadingeka, lawa kanye namanye ama-valve angaphandle kweshalofu akusona isisombululo kuphela.Kunoma yiluphi uhlelo lapho kusetshenziswa khona i-valve yokuhlola, ukufaka i-valve yangokwezifiso kungathuthukisa ukusebenza. futhi andise impilo yohlelo lwamapayipi.Lokhu kuhumushela inani elithe xaxa kanye nokonga kwezindleko zesikhathi eside.
