I-pneumatic control globe valve eyaziwa nangokuthi i-pneumatic cut-off valve, iwuhlobo lwe-actuator ohlelweni oluzenzakalelayo, oluhlanganisa i-multi-spring pneumatic film actuator noma i-piston actuator entantayo kanye ne-valve elawulayo, ethola isignali yensimbi elawulayo, elawula ukusika. , ukuxhuma noma ukushintsha uketshezi epayipini lenqubo. Inezici zesakhiwo esilula, impendulo ebucayi kanye nesenzo esithembekile. Ingasetshenziswa kabanzi ku-petroleum, imboni yamakhemikhali, i-metallurgy kanye neminye imikhakha yokukhiqiza yezimboni. Umthombo womoya we-valve yokusika umoya womoya udinga umoya ocindezelwe ohlungiwe, futhi okuphakathi nendawo okugeleza emzimbeni we-valve kufanele kungabi nakungcola kanye nezinhlayiya zoketshezi negesi.
Isilinda se-valve yeglobu ye-pneumatic siwumkhiqizo ocatshangwayo, ongahlukaniswa ube yisenzo esisodwa kanye nesenzo esiphindwe kabili ngokuya ngemodi yesenzo. Umkhiqizo osebenza ngokukodwa une-reset cylinder spring, enomsebenzi wokusetha kabusha okuzenzakalelayo wokulahlekelwa umoya, okungukuthi, lapho i-cylinder piston (noma i-diaphragm) ingaphansi kwesenzo sentwasahlobo, induku yokusunduza isilinda iphindiselwa emuva ekuqaleni. isikhundla se-cylinder (indawo yokuqala ye-stroke). Isilinda esibamba kabili asinaso isiphethu sokubuya, futhi ukuqhubekela phambili nokuhlehla kwenduku yokusunduza kufanele kuncike endaweni yokungena nokuphuma komthombo womoya wesilinda. Lapho umthombo womoya ungena ekamelweni eliphezulu le-piston, induku yokusunduza iye phansi. Lapho umthombo womoya ungena ngomgodi ongezansi wepiston, induku yokusunduza ihambela phezulu. Ngenxa yokuthi asikho isiphethu sokusetha kabusha, isilinda esibamba kabili sinokugxilwa okungaphezu kobubanzi obufanayo nesilinda esibamba esisodwa, kodwa asinawo umsebenzi wokusetha kabusha okuzenzakalelayo. Ngokusobala, izikhundla ezihlukene zokuthatha zenza i-putter ihambe ngezindlela ezahlukene. Lapho indawo yokungenisa umoya ingemuva kwenduku yokusunduza, ukungena komoya kwenza induku yokusunduza ithuthuke, le ndlela ibizwa ngokuthi isilinda esiqondile. Ngokuphambene nalokho, lapho indawo yokungena komoya isohlangothini olufanayo lwe-push rod, ukungena komoya kwenza i-push rod ibuyele emuva, ebizwa ngokuthi i-react cylinder. I-valve yeglobu yomoya ngenxa yesidingo esijwayelekile sokulahlekelwa umsebenzi wokuvikela umoya, ngokuvamile kusetshenziswa isilinda esibambayo esisodwa.

1. Isakhiwo somzimba we-valve sinesihlalo esisodwa, umkhono, isihlalo esiphindwe kabili (izindlela ezimbili ezintathu) izinhlobo ezintathu, amafomu okufaka uphawu anezimpawu zokupakisha kanye nezinhlobo ezimbili ze-bellows, uhlobo lomkhiqizo olubizwa ngokuthi ingcindezi PN10, 16, 40, 64 izinhlobo ezine, uhla lwezinga elilinganiselwe DN20 ~ 200mm. Ukushisa okusebenzayo koketshezi kusuka ku -60 kuya ku-450 ℃. Izinga lokuvuza yikilasi IV noma i-Class VI. Isici sokugeleza sivula ngokushesha;
2. i-multi-spring actuator kanye nendlela yokulungisa ixhunywe namakholomu amathathu, ukuphakama konke kungancishiswa cishe ngo-30%, futhi isisindo singancishiswa cishe ngo-30%;
3. umzimba we-valve uklanywe ngokuhambisana nesimiso se-fluid mechanics ibe isiteshi sokugeleza sokumelana nokugeleza okuphansi, i-coefficient yokugeleza elinganiselwe ikhuphuke ngo-30%;
4. Ingxenye evalekayo yezingxenye zangaphakathi zevalvu inezinhlobo ezimbili zophawu oluqinile futhi oluthambile, uhlobo oluqinile lwe-carbide enosimende engaphezulu, uhlobo lophawu oluthambile lwempahla ethambile, ukusebenza kahle kokuvala lapho kuvaliwe;
5. ama-valve angaphakathi alinganiselayo, athuthukise umehluko ovumelekile wokucindezela we-valve yokusika;
6. I-bellows seal yenza uphawu oluphelele esiqwini se-valve enyakazayo, ivimbele ukuvuza kwendawo;
7, i-piston actuator, amandla amakhulu okusebenza, ukusetshenziswa komehluko omkhulu wengcindezi.
Ngesikhathi sokuvula nokuvala i-valve yeglobu yensimbi eyenziwe ngomgunyathi, ngenxa yokuthi ukungqubuzana phakathi kwe-disc kanye nendawo yokuvala yomzimba we-valve kuncane kunaleyo ye-valve yesango, ayigugi.
I-stroke yokuvula noma yokuvala ye-valve stem imfushane kakhulu, futhi inomsebenzi wokusika othembeke kakhulu, futhi ngenxa yokuthi ukuguqulwa kwembobo yesihlalo se-valve kuhambisana nokushaywa kwe-valve disc, kulungele kakhulu ukulungiswa. wezinga lokugeleza. Ngakho-ke, lolu hlobo lwe-valve lufaneleka kakhulu ukunqunywa noma ukulawulwa nokudonsa.
Njengengcweti ye-Pneumatic Actuator Control Gate Valve kanye nesithekeli, sithembisa ukuhlinzeka amakhasimende ngesevisi yekhwalithi ephezulu yangemva kokuthengisa, okuhlanganisa nalokhu okulandelayo:
1.Nikeza isiqondiso sokusetshenziswa komkhiqizo neziphakamiso zokuwulungisa.
2.Ngokwehluleka okubangelwa izinkinga zekhwalithi yomkhiqizo, sithembisa ukuhlinzeka ngosekelo lobuchwepheshe kanye nokuxazulula izinkinga ngesikhathi esifushane kakhulu.
3.Ngaphandle komonakalo odalwe ukusetshenziswa okuvamile, sinikeza ukukhanda kwamahhala kanye nezinsizakalo zokushintshwa.
4.Sithembisa ukuphendula ngokushesha ezidingweni zesevisi yamakhasimende ngesikhathi sewaranti yomkhiqizo.
5. Sinikeza ukwesekwa kwezobuchwepheshe kwesikhathi eside, ukubonisana nge-inthanethi kanye nezinsizakalo zokuqeqesha. Umgomo wethu uwukunikeza amakhasimende umuzwa wesevisi ongcono kakhulu nokwenza ulwazi lwamakhasimende lube mnandi futhi lube lula.
