Umgomo we-valve ye-butterfly ye-UPVC ephefumulayo ukuhlangabezana nezidingo zezikhathi ezahlukene. Umgomo we-pneumatic entshaI-valve yebhabhathane ye-UPVCinama-degree angu-0-90, ama-degree angu-0-120, kanye nama-degree angu-0-180. Ama-valve e-butterfly e-UPVC asebenzisa umoya angaphinde ahlinzeke ngama-actuator e-angular stroke afana nama-degree angu-0-140. Ama-degree angu-0-160, njll., lapho kukhethwa i-valve ye-butterfly ye-UPVC esebenzisa umoya, inani lokuphepha liyangezwa ku-torque enqunyiwe ukuze kwandiswe inani lokuphepha ngo-25%, i-valve ye-butterfly ye-UPVC esebenzisa umoya engagcobi i-slurry liquid medium ikhulisa inani lokuphepha ngo-30%, i-valve ye-butterfly ye-UPVC esebenzisa umoya. I-gas medium eyomile engagcobi ikhulisa inani lokuphepha ngo-40%, i-gas engagcobi i-pneumatic ikhipha izinto ezincane ikhulisa inani lokuphepha ngo-60%, kanti i-valve ye-butterfly ye-UPVC esebenzisa umoya ikhulisa inani lokuphepha ngo-20% ye-lubricating medium ehlanzekile, ephansi. Inani lokuphepha elishiwo ngenhla Kuyisincomo senkampani futhi sihloselwe ukubhekisela kuphela. Ilungelo lokushicilela lokuhlela lingelaseShanghai Huanqi. Ngeke kube nesaziso lapho okuqukethwe kulo mbhalo kushintsha, futhi inkampani inelungelo lokugcina lokuhumusha.
I-pneumatic valve butterfly ye-UPVC i-actuator pneumatic (evame ukubizwa ngokuthi i-pneumatic head) ibizwa nangokuthi i-pneumatic actuator noma idivayisi ye-pneumatic. Iyi-actuator esebenzisa umfutho womoya ocindezelwe ukushayela ukuvula nokuvala noma ukulungisa ama-valve.Amavalvu ebhabhathane e-UPVCikakhulukazi zakhiwe ngamasilinda omoya. Ama-piston, imiphini yegiya, izivalo zokugcina, izivalo, izikulufo, njll., ama-actuator omoya ngokuvamile asetshenziswa nezinhlobo ezahlukene zama-valve, i-pneumaticAmavalvu ebhabhathane e-UPVC, okuhlanganisa nemiyalelo yokuvula, imikhawulo yokushaya, ama-valve e-solenoid, ama-positioner, izingxenye zomoya, incwadi yemiyalelo Indlela yokusebenza, impendulo yesignali nezinye izingxenye, ukuvulwa kwe-valve, ukuvala, ukuthi kuvulwe malini, nokuthi kuvalwe malini, konke kulawulwa umoya ocindezelwe. I-Shanghai Huanqi Pneumatic UPVC butterfly valve actuator iyasebenza. Ama-actuator omoya angahlukaniswa abe yi-single-acting kanye ne-double-acting ngokwesimo sesenzo. Ama-actuator asebenza kabili avula umoya futhi avalwe, okungukuthi, lapho kuvulwa umoya, ukuphefumula kuvaliwe, futhi lapho umthombo womoya ulahlekile, Akukho senzo, hlala endaweni, futhi ama-actuator asebenza kanye anomsebenzi wokubuya kwentwasahlobo. Ngokuvamile, kuvame ukuba nezinhlobo ezivaliwe futhi ezivame ukuvuleka, okungukuthi, ukuphefumula kuvuliwe. Lapho umthombo womoya ulahlekile, i-valve ye-UPVC butterfly e-pneumatic ibuyela esimweni sokuqala ngokuzenzakalelayo. Isetshenziswa kaningi ezimweni zokusebenza, futhi i-valve ingavalwa ngokushesha noma ivulwe lapho kwenzeka ukwehluleka okungazelelwe lapho ukunikezwa kwegesi kulahleka.

Isimiso sokusebenza se-valve ye-butterfly ye-UPVC esebenza kabili ye-pneumatic actuator:

I-valve ye-butterfly ye-UPVC yomoya, lapho ingcindezi yomthombo womoya ingena emgodini ophakathi kwama-piston amabili esilinda kusukela echwebeni lomoya (2), ama-piston amabili ayahlukaniswa bese eqhubekela emaphethelweni amabili esilinda. I-rack iqhuba ngokuvumelanisa i-output shaft (igiya) ukuze ijikeleze ngokuphambene newashi, i-valve ye-butterfly ye-UPVC yomoya, ngokuphambene nalokho, lapho ingcindezi yomthombo womoya ingena emakamelweni omoya kuzo zombili iziphetho zesilinda kusukela echwebeni lomoya (4), i-valve ye-butterfly ye-UPVC yomoya ihambisa ama-piston amabili ohlangothini oluphakathi kwesilinda, kanti igumbi lomoya eliphakathi liyi-. Umoya ukhishwa ngechwebeni lomoya (2), kanti i-valve ye-butterfly ye-UPVC yomoya ngesikhathi esisodwa ibangela ukuthi ama-racks amabili e-piston aqhube ngokuvumelanisa i-output shaft (igiya) ohlangothini oluhambisana newashi. (Uma i-piston ifakiwe ohlangothini oluphambene, i-output shaft izoba ukujikeleza okuphambene)
