Umgomo we-pneumatic UPVC butterfly valve ukuhlangabezana nezidingo zezikhathi ezahlukene. Umgomo we-pneumatic entshaUPVC uvemvane valvehas 0-90 degrees, 0-120 degrees, kanye 0-180 degrees. Amavalvu ovemvane e-UPVC anganikeza ama-angular stroke actuators afana namadigri angu-0-140. 0-160 degrees, njll., lapho kukhethwa i-valve uvemvane we-UPVC womoya, inani lokuphepha liyengezwa kuthoshi enqunyiwe ukuze kwenyuswe inani lokuphepha ngo-25%, ivalve yovemvane ye-UPVC engagcotshi uketshezi oluncibilikayo yomoya inyusa inani lokuphepha. ngo-30%, i-valve uvemvane i-UPVC yomoya Igesi eyomile engagcotshisiwe inyusa inani lokuphepha ngo-40%, Igesi engagcotshisiwe edluliswa yizinhlayiyana inyusa inani lokuphepha ngo-60%, futhi ivalve uvemvane we-UPVC womoya inyusa inani lokuphepha ngo-20% endaweni yokugcoba, enokungqubuzana okuphansi. Inani lokuphepha elishiwo ngenhla Kuyisincomo sethiyori senkampani futhi kubhekiselwa kuso kuphela. I-copyright yokuhlela ingeye-Shanghai Huanqi. Ngeke kube nesaziso uma okuqukethwe kulo mbhalo kushintsha, futhi inkampani inelungelo lokugcina lokutolika.
I-pneumatic UPVC butterfly valve pneumatic actuator (evame ukubizwa ngokuthi ikhanda eliphefumulayo) liphinde libizwe ngokuthi i-actuator yomoya noma idivayisi yomoya. Kuyi-actuator esebenzisa umfutho womoya ocindezelwe ukushayela ukuvula nokuvala noma ukulungisa ama-valve. I-pneumaticI-UPVC butterfly valvesikakhulukazi akhiwe ngamasilinda omoya. Ama-piston, ama-giya shaft, ama-end cap, ama-seal, izikulufu, njll., ama-pneumatic actuators ngokuvamile asetshenziswa nezinhlobo ezahlukene zamavalvu, umoya womoya.I-UPVC butterfly valves, okuhlanganisa nemiyalelo yokuvula, imikhawulo yokushaywa unhlangothi, ama-valve e-solenoid, ama-positioners, izingxenye ze-pneumatic, imanuwali Umshini, impendulo yesignali nezinye izingxenye, ukuvulwa kwe-valve, ukuvala, ukuvuleka okungakanani, ukuvala okungakanani, konke kulawulwa umoya ocindezelweyo. . I-Shanghai Huanqi Pneumatic UPVC butterfly valve pneumatic actuator iyasebenza. Ama-actuator e-pneumatic angahlukaniswa abe yi-single-acting kanye ne-double-acting ngokuya ngohlobo lwesenzo. Ama-actuator asebenza kabili avula umoya futhi avale umoya, okungukuthi, lapho kuvulwa umoya, umoya uvaliwe, futhi lapho umthombo womoya ulahlekile , Akukho senzo, hlala endaweni, futhi ama-actuator asebenza ndawonye anomsebenzi. yokubuya kwentwasahlobo. Ngokuvamile, kunezinhlobo ezivaliwe futhi ezivame ukuvuleka, okungukuthi, ukungena komoya kuvuliwe. Lapho umthombo womoya ulahlekile, ivalve uvemvane we-UPVC womoya izihlela kabusha ngokuzenzakalelayo esimweni sokuqala. Isetshenziswa kaningi ezimweni zokusebenza, futhi i-valve ingavalwa ngokushesha noma ivuleke lapho ukwehluleka okungazelelwe kwenzeka lapho ukunikezwa kwegesi kulahleka.

I-pneumatic UPVC butterfly valve isimiso sokusebenza se-pneumatic actuator:

Ivalvu uvemvane we-UPVC womoya, lapho umfutho womthombo womoya ungena endaweni ephakathi kwamaphistoni amabili esilinda ukusuka endaweni yomoya (2), amaphistoni amabili ayahlukaniswa futhi aya ngasekugcineni okubili kwesilinda. I-rack ishayela ngokulinganayo i-shaft ephumayo (igiya) ukuze ijikelezise ngokuphambene newashi, i-pneumatic UPVC butterfly valve, ngokuphambene nalokho, lapho umfutho womthombo womoya ungena emagumbini omoya kuzo zombili iziphetho zesilinda ukusuka esikhumulweni somoya (4), i-UPVC yomoya. i-butterfly valve ihambisa ama-piston amabili iqonde maphakathi nesilinda, kanti igumbi lomoya eliphakathi nendawo lithi Umoya uphuma phakathi. Imbobo yomoya (2), kanye nevalve yovemvane ye-UPVC yomoya ngesikhathi esisodwa ibangela ukuthi ama-piston rack amabili ashayele ngokuhambisanayo i-shaft yokuphumayo (igiya) ukuze ijikelezise ngendlela yewashi. (Uma i-piston ifakwe ngakolunye uhlangothi, i-shaft ephumayo izophenduka ukuzungeza)
