I-API Izingcezu Ezintathu Ze-Carbon Steel Flanged Motorized trunnion ball valve China Factory
Iyini i-Motorized trunnion ball valve?
AI-valve yebhola ye-trunnion enemotokusho ukuthi ibhola livinjelwa ama-bearings futhi livunyelwe kuphela ukuzungeza, iningi lomthwalo we-hydraulic lisekelwa yizingqinamba zeSistimu, okuholela ekucindezelekeni okuphansi kokuthwala futhi akukho ukukhathala kwe-shaft.
Umfutho wepayipi ushayela isihlalo esikhuphuka nomfula ngokumelene nebhola elimile ukuze ukucindezela komugqa kuphoqe isihlalo esikhuphuka nomfula singene ebholeni okwenza ukuthi livaleke.I-anchoring eyimishini yebhola idonsa ukusunduza kumfutho womugqa, ivimbele ukungqubuzana okweqile phakathi kwebhola nezihlalo, ngakho-ke ngisho nange-torque elinganiswe ngokugcwele yokusebenza ihlala iphansi.Lokhu kunenzuzo ikakhulukazi uma i-valve yebhola icushiwe ngoba yehlisa usayizi we-actuator futhi ngaleyo ndlela izindleko zizonke zephakheji yokuvula i-valve.
Izinzuzo zedizayini yebhola le-trunnion i-torque ephansi yokusebenza, ukusebenza kalula, ukugqokwa kwesihlalo okuncishisiwe (Ukuhlukaniswa kwesiqu/ibhola kuvimbela ukulayishwa okuseceleni nokuguga kwezihlalo ezisezingeni eliphansi ezithuthukisa ukusebenza nempilo yesevisi), ukusebenza kokuvala okuphakeme kukho kokubili ingcindezi ephezulu nephansi (okuhlukile indlela yasentwasahlobo kanye nokucindezela komugqa okhuphuka nomfula kusetshenziswa njengendlela yokuvala ibhola elimile ukuze kufakwe umfutho ophansi kanye nokucindezela okuphezulu).
Izici eziyinhloko ze-NORTECH Motorized trunnion ball valve
1. I-Double Block and Bleed(DBB)
Lapho i-valve ivaliwe futhi imbobo emaphakathi ithululwa nge-valve yokukhipha, izihlalo ezikhuphuka nomfula ziyovimba ngokuzimela.Omunye umsebenzi wedivayisi yokukhipha ukuthi isihlalo se-valve singabhekwa uma kukhona ukuvuza ngesikhathi sokuhlolwa.
11.Blow-out Isiqu Sobufakazi
Isiqu samukela ukwakheka kobufakazi bokushaywa umoya. Isiqu siklanywe ngesitebhisi sonyawo phansi ukuze uma kubekwe ikhava engenhla nesikulufu, isiqu ngeke sishaywe umoya ngisho nalapho ukucindezela okungavamile kukhuphuka. i-valve cavity.
Isiqu Sobufakazi Sokushaywa
2.I-Torque Esebenzayo Ephansi
Ivalvu yebhola yepayipi le-trunnion ithatha isakhiwo sebhola le-trunnion kanye nesihlalo se-valve esintantayo, ukuze ithole i-torque ephansi ngaphansi kwengcindezi yokusebenza.Isebenzisa i-PTFE ezithambisayo kanye ne-metal sliding bearing ukuze kuncishiswe i-coefficient yokungqubuzana ibe phansi kakhulu ngokuhambisana nokuqina okuphezulu kanye nesiqu sokucoleka okuphezulu.
3.Idivayisi Yokuvalwa Kwezimo Eziphuthumayo
Amavalvu ebhola anobubanzi obungaphezulu noma obulingana no-6'(DN150) wonke aklanywe ngendlela yomjovo wokuvala isivalo esiqwini nasesihlalweni.Uma indandatho yesihlalo noma i-stem O ring ilimele ngenxa yengozi, isivalo esihambisanayo singajovwa ngomjovo we-sealant ukugwema ukuvuza okuphakathi kweringi yesihlalo nesiqu.
13.Isiqu Sokunweba
Ngokuqondene nevalvu eshumekiwe, isiqu esinwetshiwe singanikezwa uma kudingeka ukusebenza komhlabathi.Isiqu esinwetshiwe sakhiwe ngesiqu, ivalve yomjovo we-sealant, kanye nevalve yokukhipha amanzi enganwetshwa iye phezulu ukuze kube lula ukusebenza.Abasebenzisi kufanele bakhombise izidingo zesiqu sesandiso kanye nobude lapho befaka ama-oda.Ku-valve yebhola eqhutshwa ngogesi, i-pneumatic kanye ne-pneumatic - hydraulic actuators, ubude besiqu esinwetshiwe kufanele busuke phakathi nendawo yepayipi ukuya phezulu.
Umdwebo wohlelo lwesiqu sesandiso
4.I-Fireproof Structure Design
Uma kwenzeka umlilo ngesikhathi kusetshenziswa i-valve, indandatho yesihlalo, isiqu O indandatho kanye ne-flange ephakathi O indandatho eyenziwe nge-PTFE,irabha yezinye izinto ezingezona ezensimbi izobola noma yonakaliswe ngaphansi kwezinga lokushisa eliphezulu.Ngaphansi kwengcindezi ye-medium, ibhola i-valve izophusha isibambi sesihlalo ngokushesha ibheke ebholeni ukuze yenze indandatho yophawu lwensimbi ixhumane nebhola futhi yakhe insimbi eyisisekeli esakhiweni sokuvala sensimbi, esingalawula ngempumelelo ukuvuza kwevalvu.
5.Anti-static Isakhiwo
I-valve yebhola iklanywe ngesakhiwo esingaguquki futhi yamukela idivayisi yokukhipha ugesi omile ukuze yakhe ngokuqondile umzila omile phakathi kwebhola nomzimba ngesiqu, ukuze ikhiphe ugesi ongashintshi okhiqizwa ngenxa yokungqubuzana ngesikhathi sokuvulwa nokuvala. ibhola kanye nesihlalo epayipini, ukugwema umlilo wokuqhuma okungenzeka udalwe inhlansi engashintshi kanye nokuqinisekisa ukuphepha kohlelo.
Uhlangothi olungezansi komfula: Uma ingcindezi ethi “Pb” ngaphakathi kwe-valve Cavity ikhuphuka, amandla asetshenziswa ku-A3 angaphezulu kwalawo aku-A4.Njengo-A3-A4=B2, umehluko wengcindezi ku-B2 uzonqoba amandla entwasahlobo ukuze wenze isihlalo sikhululwe ebholeni futhi ubone ukukhululeka kwe-valve engxenyeni engezansi komfula ngemva kwalokho, isihlalo nebhola kuzovalwa futhi ngaphansi kwesenzo sasentwasahlobo. .
8.Ukuvalwa Okukabili (i-Double piston)
Ivalvu yebhola yepayipi le-trunnion ingaklanywa ngesakhiwo sokuvala kabili ngaphambi nangemuva kwebhola ngezimo ezithile zesevisi ezikhethekile kanye nezidingo zomsebenzisi.Inomphumela we-piston kabili.Ngaphansi kwesimo esivamile, i-valve ngokuvamile isebenzisa ukuvala okuyisisekelo. Lapho isihlalo esiyinhloko esisivalayo sonakaliswa futhi sibangela ukuvuza, isihlalo sesibili singadlala umsebenzi wokuvala futhi sithuthukise ukwethembeka kokuvala.isihlalo samukela isakhiwo esihlanganisiwe.Isigxivizo esiyinhloko siyinsimbi kuya kwesensimbi.Isigxivizo sesibili i-fluorine rubber O ring engaqinisekisa ukuthi i-valve yebhola ingafinyelela ukuvala izinga le-bubble.Uma umehluko wengcindezi uphansi kakhulu, isihlalo sokuvala sizocindezela ibhola esenzweni sasentwasahlobo ukuze kutholakale uphawu lokuqala.Lapho umehluko wengcindezi ukhuphuka, amandla okuvala isihlalo nomzimba azokhula ngokufanele ukuze avale ngokuqinile isihlalo nebhola futhi aqinisekise ukusebenza kahle kokuvala.
Ukuvalwa okuyisisekelo: Phezulu komfula.
Uma umehluko wengcindezi uphansi noma ungekho umehluko wengcindezi, isihlalo esintantayo sizonyakaza nge-axially eduze kwe-valve ngaphansi kwesenzo sasentwasahlobo futhi sishaye isihlalo sibheke ebholeni ukuze sigcine ukuvala okuqinile.Uma isihlalo sevalvu singaphezu kwamandla asetshenziswa endaweni A1,A2- A1=B1.Ngakho-ke, amandla ku-B1 azophusha isihlalo siye ngaseBholeni futhi abone ukuvaleka okuqinile kwengxenye ekhuphuka nomfula.
9.Idivayisi Yokusiza Ukuphepha
Njengoba i-valve yebhola iklanywe ngokuvala okuphambili okuphambili nokwesibili okunomphumela we-piston kabili, futhi indawo ephakathi ayikwazi ukuqaphela ukukhululeka kokucindezela okuzenzakalelayo, i-valve yokusiza ukuphepha kufanele ifakwe emzimbeni ukuze kuvinjelwe ingozi yokulimala ngokweqile. ngaphakathi kwesikhala se-valve okungenzeka ngenxa yokwanda okushisayo kwe-medium.Ukuxhuma kwe-valve yokusiza ukuphepha ngokuvamile kuyi-NPT 1/2.Elinye iphuzu okufanele liqashelwe ukuthi i-valve yokusiza ukuphepha ikhishelwa ngqo emkhathini.Uma kwenzeka ukudedelwa okuqondile emkhathini kungavunyelwe, siphakamisa ukuthi i-valve yebhola enesakhiwo esikhethekile sokukhululeka kokucindezela okuzenzakalelayo ngasemfudlaneni ongaphezulu kufanele kusetshenziswe.Bheka okulandelayo ukuze uthole imininingwane.Sicela uyikhombise ngokulandelana kwayo uma ungayidingi ivalvu yokusiza ukuphepha noma uma ungathanda ukusebenzisa ivalvu yebhola enesakhiwo esikhethekile sokukhululeka kokucindezela okuzenzakalelayo ngasemfuleni ongaphezulu.
10.Isakhiwo Esikhethekile Sokukhululwa Kwengcindezi Okuzenzakalelayo Kubhekise Kumfudlana Ephezulu
Njengoba i-valve yebhola iklanywe ngokuvaleka okuphambili okuphambili nokwesibili okunomphumela we-piston kabili, futhi umgodi ophakathi awukwazi ukubona ukukhululeka kokucindezela okuzenzakalelayo, i-valve yebhola ith isakhiwo esikhethekile siyanconywa ukuhlangabezana nezidingo zokunciphisa ukucindezela okuzenzakalelayo nokuqinisekisa ukuthi akukho kungcola. emvelweni.Esakhiweni, umfudlana ongaphezulu uthatha ukuvaleka okuyisisekelo bese umfudlana ongezansi uthatha ukuvala okuyisisekelo nokwesibili Lapho i-valve yebhola ivaliwe, umfutho osesikhaleni sevalvu ungathola ukukhululeka kokucindezela okuzenzakalelayo kumfudlana ongenhla, ukuze ugweme. ingozi ebangelwa ukucindezela komgodi.Lapho isihlalo sokuqala sonakele futhi sivuza, isihlalo sesibili singadlala futhi umsebenzi wokuvala. Kodwa ukunakekelwa okukhethekile kufanele kukhokhwe ekugelezeni kwe-valve yebhola. Ngesikhathi sokufakwa. Qaphela umfula okhuphukayo kanye izikhombisi-ndlela ezingezansi.Bheka emidwebeni elandelayo ukuze uthole isimiso sokuvala i-valve ngesakhiwo esikhethekile
Umdwebo womgomo wokuvala i-valve yebhola phezulu nomfula
Umdwebo wesimiso sokukhululeka kwengcindezi ye-valve yembobo yebhola emfudlaneni ongaphezulu kanye nokuvala umfula ongezansi
