Imikhiqizo
I-Pneumatic Actuator Control Globe Valve
✧ Incazelo
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, i-cylinder push rod 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 lepiston, induku yokuphusha ihlehla iye phansi.Lapho umthombo womoya ungena ngomgodi ophansi 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 sisebenzisa isilinda esibambayo esisodwa.

✧ Izinzuzo ze-Pneumatic Actuator Control Globe Valve
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.
