I-Titanium B367 GC-2 Globe Valve
Kunezinhlobo ezi-3 zezindlela zokuxhuma: uxhumano lwe-flange, uxhumano lwe-threaded, nokuxhumeka okuhlanganisiwe kodwa. Ngemva kokuvela kwamavalvu azivalayo, indlela yokugeleza emaphakathi yevalvu yokuvala iyashintsha ukusuka ngenhla kwe-valve disc ukuze ingene egumbini levalvu. Ngalesi sikhathi, ngaphansi kwengcindezi ye-medium, amandla okuvala i-valve mancane, kuyilapho amandla okuvula i-valve makhulu, futhi ububanzi besiqu se-valve bungancishiswa ngokufanayo. Ngesikhathi esifanayo, ngaphansi kwesenzo se-medium, leli fomu le-valve nalo liqinile. I-"Three Modernizations" yama-valve ezweni lakithi yake yabeka ukuthi indlela yokugeleza kwama-valve embulunga kufanele isuke phezulu iye phansi. Lapho i-valve yokuvala ivuliwe, ukuphakama kokuvula kwediski ye-valve kungu-25% kuya ku-30% we-diameter yegama. Lapho izinga lokugeleza selifinyelele umkhawulo walo, libonisa ukuthi i-valve ifinyelele endaweni evulekile ngokugcwele. Ngakho-ke indawo evulekile ngokugcwele ye-valve yokuvala kufanele inqunywe ngokushaya kwediski ye-valve.
Ingxenye evulayo nevalayo yevalvu yokumisa, i-Globe Valve, iyi-disc ye-valve emise okwepulaki, enendawo eyisicaba noma eyi-conical endaweni evalayo. I-valve disc ihamba ngomugqa oqondile phakathi nendawo yesihlalo se-valve. Indlela yokunyakaza yesiqu se-valve, evame ukubizwa ngokuthi induku efihliwe, ingabuye isetshenziselwe ukulawula ukugeleza kwezinhlobo ezahlukene zoketshezi olunjengomoya, amanzi, isitimu, imidiya eyonakalisayo ehlukahlukene, udaka, uwoyela, insimbi ewuketshezi, kanye nemidiya ekhipha imisebe. ngokusebenzisa uhlobo lwenduku yokuphakamisa nokujikeleza. Ngakho-ke, lolu hlobo lwe-valve yokuvala lufaneleka kakhulu ngezinjongo zokusika, zokulawula, kanye ne-throttling. Ngenxa yokuvuleka okufushane noma ukuvala ukushaywa kwesiqu se-valve kanye nomsebenzi othembeke kakhulu wokunqamula, kanye nobudlelwano obulinganayo phakathi kokushintshwa kokuvuleka kwesihlalo se-valve kanye nokushaywa kwe-valve disc, lolu hlobo lwe-valve lubaluleke kakhulu. ilungele ukulawula ukugeleza.

Izici Ezengeziwe
Umgomo wokusebenza wama-valve eglobhu ensimbi ukuzungezisa i-valve ukwenza i-valve ingavimbeki noma ivinjwe. Ama-valve esango alula, amancane ngosayizi, futhi angenziwa abe ama-diameter amakhulu. Zinokubekwa uphawu okuthembekile, ukwakheka okulula, nokugcinwa ngendlela efanele. Indawo yokuvala kanye nendawo eyindilinga kuvame ukuba sesimweni esivaliwe futhi ayiguguleka kalula ngabezindaba. Zisetshenziswa kabanzi ezimbonini ezahlukahlukene.
Ipheya elivalayo levalvu yokuvala liqukethe indawo yokuvala yediski ye-valve kanye nendawo yokuvala yesihlalo sevalvu. Isiqu se-valve sishayela i-disc ye-valve ukuze ihambe iqonde emgqeni omaphakathi wesihlalo se-valve. Ngesikhathi sokuvula nokuvala i-valve yokuvala, ukuphakama kokuvula kuncane, okwenza kube lula ukulungisa izinga lokugeleza, futhi kulula ukukhiqiza nokugcina, ngezinhlelo eziningi zokucindezela.
Indawo yokuvala ye-valve yeglowubu ayigqoki kalula noma ayiklwebheki, futhi asikho isihlobo esishelelayo phakathi kwediski ye-valve nendawo yokuvala isihlalo se-valve phakathi nenqubo yokuvula nokuvala. Ngakho-ke, ukugqokwa nokuklwebheka endaweni yokuvala kuncane, okuthuthukisa impilo yesevisi ye-pair yokuvala. I-valve yembulunga ine-valve disc stroke encane kanye nokuphakama okuncane ngesikhathi sokuvala okugcwele. Ukungalungi kwe-valve yokuvala ukuthi ine-torque enkulu yokuvula nokuvala futhi kunzima ukufeza ukuvulwa nokuvala ngokushesha. Ngenxa yamashaneli okugeleza ahlukumezayo emzimbeni we-valve, ukumelana nokugeleza koketshezi kuphezulu, okuholela ekulahlekelweni okukhulu kwamandla oketshezi epayipini.
Izici zesakhiwo:
1. Vula futhi uvale ngaphandle kokungqubuzana. Lo msebenzi uyixazulula ngokuphelele inkinga yama-valve endabuko athinta ukubekwa uphawu ngenxa yokungqubuzana phakathi kwezindawo zokuvala.
2. Isakhiwo esifakwe phezulu. Amavavu afakwe kumapayipi angahlolwa ngokuqondile futhi alungiswe ku-inthanethi, okunganciphisa ngempumelelo isikhathi sokungasebenzi kwedivayisi kanye nezindleko eziphansi.
3. Umklamo wesihlalo esisodwa. Iqede inkinga yokukhuphuka kwengcindezi engavamile endaweni yegumbi le-valve, ethinta ukuphepha kokusetshenziswa.
4. Idizayini yetorque ephansi. Isiqu se-valve esinomklamo okhethekile wesakhiwo singavulwa kalula futhi sivalwe nge-valve yesibambo esincane nje.
5. Isakhiwo sokubeka uphawu esimise okwe-Wedge. Ama-valve ancike emandleni kamishini anikezwa isiqu se-valve ukucindezela inkaba yebhola esihlalweni se-valve nokuvala, ukuqinisekisa ukuthi ukusebenza kokuvala kwe-valve akuthintwa izinguquko zomehluko wengcindezi yamapayipi, nokusebenza okuthembekile kokuvala kuqinisekisiwe ngaphansi kokusebenza okuhlukahlukene. izimo.
6. Isakhiwo sokuzihlanza sendawo yokubeka uphawu. Lapho i-sphere inyakaza isuka esihlalweni se-valve, uketshezi olusepayipini ludlula ngokufanayo endaweni evalekayo yendawo nge-engeli engu-360 °, okungagcini nje ngokuqeda ukuhlinzwa kwendawo kwesihlalo se-valve ngoketshezi olunesivinini esikhulu, kodwa futhi nokugudluza. ukunqwabelana endaweni yokuvala, ukufeza inhloso yokuzihlanza.
7. Imizimba yamavalvu kanye nekhava enobubanzi obungaphansi kwe-DN50 iyizingxenye ezifojiwe, kuyilapho lezo ezinobubanzi obungaphezulu kwe-DN65 ziyizingxenye zensimbi ezisansimbi.
8. Amafomu okuxhumana phakathi komzimba we-valve nesembozo se-valve ahlukile, okuhlanganisa ukuxhumana kwe-clamp pin shaft, uxhumano lwe-flange ye-gasket, nokuxhumeka kwentambo yokuzivala.
9. Izindawo zokuvala zesihlalo sevalvu kanye nediski zonke zenziwe nge-plasma spray welding noma i-overlay welding ye-cobalt chromium tungsten hard alloy. Izindawo zokuvala zinokuqina okuphezulu, ukumelana nokugqokwa, ukumelana nokuhuzuka, nempilo ende yesevisi.
10. I-valve stem material iyinsimbi ene-nitrided, futhi ukuqina kwendawo ye-valve ye-nitrided kuphakeme, ayigugi, imelana nokunwaya, futhi imelana nokugqwala, nempilo ende yesevisi.

Izinhlelo zokusebenza
Amavalvu eglobhu e-Titanium cishe awaboli emkhathini, emanzini ahlanzekile, emanzini olwandle, nesitimu esinezinga lokushisa eliphezulu, futhi amelana nokugqwala kakhulu emithonjeni ye-alkaline. Ama-valve embulunga ye-Titanium anokumelana okuqinile nama-ion e-chloride futhi amelana kahle kakhulu ne-chloride ion corrosion. Amavalvu embulunga ye-Titanium anokumelana nokugqwala okuhle emithonjeni yezindaba efana ne-sodium hypochlorite, amanzi e-chlorine, nomoya-mpilo omanzi. Ukumelana nokugqwala kwamavalvu embulunga ye-titanium kuma-asidi aphilayo kuncike ekunciphiseni noma ekuhlanganiseni kwezakhiwo ze-asidi. Ukumelana nokugqwala kwamavalvu embulunga ye-titanium ekunciphiseni ama-asidi kuncike ekubeni khona kwama-corrosion inhibitors phakathi nendawo. Amavalvu embulunga ye-Titanium ayisindi futhi anamandla okusebenza aphezulu, futhi asetshenziswa kakhulu emkhathini. Amavalvu eglowubhu ye-Titanium angakwazi ukumelana nokuguguleka kwemithombo yezindaba egqwala ehlukahlukene, futhi angaxazulula inkinga yokugqwala okunzima ukuyixazulula kumapayipi omoya ezimboni amelana nokugqwala. Inezinzuzo zokuphepha, ukwethembeka, nempilo ende yesevisi. Isetshenziswa kakhulu embonini ye-chlor alkali, embonini ye-soda ash, embonini yezemithi, embonini kamanyolo, imboni yamakhemikhali emihle, imboni ye-textile fibre synthesis kanye nemboni yokudaya, i-asidi eyisisekelo ye-organic kanye nokukhiqizwa kukasawoti we-inorganic, imboni ye-nitric acid, njll.
