Ukuhlukaniswa kwe-pneumatic valvei-valveizidingo zezici ezinomthelela
A, izinhlobo zokhiye ze-pneumatic valve:
1) Ivalvu elawulayo yohlobo lwe-v-umoya
2) I-valve ye-pneumatic o-type yokunqamula
3) i-torsion cylinder valve
4) i-electromagnetic induction pneumatic butterfly valve
5) I-pneumatic straight drive inqubo ye-pneumatic butterfly valve
6) I-valve yokulawula kagesi
Okwesibili, ivalvu elawulayo yohlobo lwe-v ye-pneumatic:
Ukusetshenziswa okuyinhloko nezici
A, ukusetshenziswa okuyinhloko Isakhiwo se-bevel rotary, sona kanye nesicelo sendawo ye-valve esisekela indawo, singaqedela ukulungiswa kwesilinganiso; I-valve core yohlobo lwe-V ifanele zonke izinhlobo zezindawo zokulungisa, ene-coefficient enkulu yokugeleza kukalwe, isilinganiso esiguquguqukayo, umphumela wokuvala muhle kakhulu, izici zokulungisa ezizwelayo eziyiziro, usayizi omncane, ukufakwa okuqamba amanga okuqondile. Ifanele ukulawula umhwamuko, umhwamuko, uketshezi nezinye izinto.
B, izici: iyisakhiwo esijikelezayo se-bevel, esakhiwe ngepuleti lesekhethi kawoyela emise okwe-v, i-actuator yomoya, indawo yokubuka kanye nezinye izesekeli; Kukhona izici ezifanayo zokuqala zokugeleza kwesilinganiso sekhulu; Isakhiwo esinezingqimba ezimbili, i-torque egijimayo incane, inokunemba okuhle kanye nezinga lokungeniswa kazibuthe; Ikhono elihle lokusika.
C, ukucindezelwa komoya kwe-piston rod actuator njengedivayisi yamandla, ngokuya ngokunyakaza kokuqina kwenduku ye-piston ukuze kuthuthukiswe ingalo egoqayo ukuze yenze ama-degree angama-90 wokuzungezisa, ukuze i-valve ivuleke futhi ivaleke ngokugcwele. Iqukethe: ukulungisa i-anchor bolt, i-actuator housing, uhlobo lwengalo egoqayo, umkhono wesilinda, i-cylinder shaft, i-piston rod, i-crankshaft, i-universal shaft.
D, umsebenzi wevalvu yokulawula uhlobo lwe-pneumatic yevalvu yokulawula ehambayo yokuqala nge-actuator nenhlangano elawulayo. I-actuator iyingxenye yamandla okushayela evalvu elawulayo, eyenza amandla okushayela ahambisanayo ngokosayizi wengcindezi yesignali yedatha yokukhohlisa ukuze kuthuthukiswe ukulungiswa kokuma kwenhlangano. I-oil circuit plate iyingxenye yokulawula ye-valve yokulawula umoya. Iphinde ithinte into elawulayo ukulungisa ukugeleza okuphelele koketshezi.
Izici ezithonya izidingo ze-valve
Izici ezithonya izidingo ze-valve
Kusukela ngoJanuwari kuya kuJuni ngo-2013, i-Wenzhou, indawo eyinhloko yokukhiqiza ama-valve e-China, yathumela imikhiqizo yama-valve ama-batches angu-8109, ngokukhula konyaka ngonyaka ka-0.61%, isabelo sokuthekelisa sama-DOLLA ayizigidi ezingu-260, ukwehla konyaka nonyaka. ka-2.98%, ukwehla okuqhubekayo, futhi ngo-2012, i-quota ye-Wenzhou valve yokuthekelisa i-1-6 ikhuphuke yafinyelela ku-42%, igebe elibalulekile phakathi kwamaqembu amabili edatha.
I-valve edingwa imvelo yomnotho womhlaba umonakalo inkulu, inkambu ye-valve yaseChina kufanele ngomoya ophansi, ithuthukise ikhono labo lokungenisa nokuthekelisa ukuhwebelana ngengozi yohwebo, ikakhulukazi yezidingo eziphansi zezobuchwepheshe zemikhiqizo ye-valve evamile ephakathi, ehlanganyela enkampanini eminingi, i-homogeneity yomkhiqizo ingaphezulu. okungathi sína, ukukhiqiza ngokweqile, ukwehla kwezinga lenzuzo, Izinkampani eziningi zamavalvu zisekelwe ekwandiseni ukuthunyelwa kwempahla kwamanye amazwe ukuze ziphile, isilinganiso sokuthekelisa kwempahla yama-valve ngokukhula kancane kancane.
Kodwa ukwandisa ukuthunyelwa kwamanye amazwe akusona isimo esibucayi sokuthuthukiswa kwemboni ye-valve yokucubungula i-panacea, futhi kunzima ukugwema izinkinga ezithile ngokubukeka kwedatha yedatha yokuthekelisa ekhombisa kancane kancane: izinkampani eziningi zokuthekelisa zama-valve zokwandisa ngokwazo isabelo semakethe sokuthekelisa, kusukela ekulinganiseni ukuncintisana kwamanani emakethe yaseChina, ukuncintisana kwamanani amabi. iyaqhubeka ukwanda. Izinkampani eziningi ezincane - neziphakathi ziyaqhudelana ngentengo ukuze zithole ulwazi lokuhleleka kwamazwe ngamazwe. Kodwa-ke, amanye amabhizinisi amancane naphakathi ngentengo ephansi yomkhiqizo ukuze athole ama-oda aphesheya kwezilwandle, ukuze kulawulwe kangcono izindleko, kuvame ukushoda. Ngenxa yalokhu, imikhiqizo eqediwe ayifaneleki futhi ukwethembeka kochungechunge lwemboni yezingxenye zama-valve kusengozini. ** Okuthusayo ukuthi ngokuhamba kwesikhathi, uchungechunge lwemboni yezingxenye zamavalvu e-China kungenzeka futhi luhlupheke ngokuvikeleka kwezohwebo emakethe yomhlaba.
Kulesi sigaba, ukuthunyelwa kwama-valve kakhulu kususwa ngama-DOLLA, futhi ingcuphe yezinga lokushintshaniswa ebangelwa ukwazisa kwe-RENMINBI nayo yengeza uphethiloli emlilweni. Abanye abakhiqizi bamavalvu abanalo ikhwalithi yomkhiqizo eqinile, mbumbulu kanye ne-shoddy, balimaza imali engenayo yemboni efanayo e-China kanye nesithombe somkhiqizo wezimpahla ezithunyelwa kwamanye amazwe zamavalvu e-China. Ngiyaxolisa, okuholele ekutheni imajini yokukhishwa kwe-valve iqhubekile nokwehla.
Ukusimama komnotho wembulunga yonke kusafanele kube inqubo ehamba kancane, izidingo ze-valve yimvelo yezomnotho yomhlaba zikhulu kakhulu, inkundla ye-valve yaseChina kufanele iphendule ngomoya ophansi ukuze ithuthukise ikhono lokuxhumana ngezingozi zokungenisa nokuthumela ngaphandle, ekwandiseni ukuthekelisa ngasikhathi sinye. , futhi ayikwazi ukukhulula ingcindezi ekuthuthukisweni kwemakethe yokuthengisa yaseChina. Isisekelo senkampani singakwazi ukwenza ukuthuthukiswa kwesakhiwo sezimboni, ukuya embonini yezimpahla ze-valve ephezulu ukuze iqhubekele phambili, njengowoyela ongahluziwe, izitshalo zamandla enuzi kanye nezinye izimboni zokuthuthukiswa okubalulekile zikazwelonke, ama-valve angaphandle usayizi wemakethe ohlukile awunakunakwa.
Ngokusho kwezibalo, ngo-2013, izinkampani ze-valve zaseShayina zahlangabezana nengcindezi yokuthekelisa ukuze zandise isimo, izinkampani ze-valve kufanele ziqinise ubuchwepheshe bokuqamba, kusukela enanini eliphelele lokugcizelela, ukunwetshwa kwesikali sebhizinisi ukunaka kakhulu ukuphishekela ikhwalithi ephelele, izinzuzo zezomnotho. , futhi ithuthukise ngenkuthalo imakethe yokuthengisa yaseChina, ikhuthaze inkambiso yentuthuko enengqondo yensimu ye-valve yaseChina. Futhi ngaphansi kwezidingo zobuchwepheshe zezinye izinkampani zama-valve amancane naphakathi, zingacabangela imboni entsha yokuhlukanisa, njengokushisa kwe-valve yesihlukanisi samanzi, ithuthukise umthamo wamaphrojekthi wobunjiniyela asekela izikhungo, ithuthukise inani elengeziwe le-valve.
Imikhiqizo yepompo ye-Ze de centrifugal eya esiphakamisini sendle, umshini wokuphakamisa amabhakede angcolile, isiteshi sokuphakamisa amanzi angcolile, isiteshi sepompo esididiyelwe, iphampu ephakamisa indle, imishini yokuphakamisa indle, iphampu yasengadini, iphampu yejet, impompo ye-centrifugal, isihlukanisi se-slag, iphampu yendle, iphampu yendle engaphansi kwamanzi njenge idivayisi ehamba phambili yokuphakamisa indle. Umshini ngamunye wokuphakamisa indle uklanyelwe ukuba ube lula kakhulu ukuwufaka, futhi ngesikhathi esifanayo, kunesethi ephelele yezingxenye ezisele ezidingekayo ukuze zifakwe. Sinekhava yokuthengisa emakethe ezwakalayo I-inthanethi, ingakulethela amaphrojekthi esevisi alula, e-France, e-Europe, iningi lase-China lingaqedela umgomo oseduze wokuthenga. Imishini yokuphakamisa indle ye-Ze de ilungele abantu abajwayelekile (umndeni), i-villa yomndeni owodwa, ingadi, izinsizakalo zezentengiselwano nezinye iziza, ezigxile epayipini lokudonsa amanzi elingaphansi kwe-villa, i-drainage efanayo yaphansi, ukuphakelwa kwamanzi okuphuza asekhaya, ukuchelela engadini kanye nezinye izingcweti. kanye nemishini edidiyelwe yokuthutha emanzini nezixazululo!
