Wafer Butterfly Valves Opanga

Chovala chagulugufe chamtundu wa butterfly valve chimayikidwa m'mimba mwake cha chitoliro. Mu cylindrical channel of the butterfly valve body, mbale yagulugufe yooneka ngati chimbale imazungulira mozungulira ndi ngodya yozungulira ya 0 ° - 90 °, yomwe imatha kugwira ntchito yoyendetsera kayendetsedwe kake. Pamene gulugufe mbale atembenuza 90 °, valavu kufika pazipita kutsegula.

Valovu yagulugufe ya wafer ndi yophweka popanga, yaying'ono mu voliyumu ndi yopepuka kulemera kwake, ndipo imapangidwa ndi magawo ochepa chabe. Komanso, valavu akhoza kutsegulidwa ndi kutsekedwa mwamsanga kokha pozungulira 90 °, ndipo ntchito ndi yosavuta. Pa nthawi yomweyi, valve ili ndi makhalidwe abwino olamulira madzimadzi. Pamene valavu ya gulugufe ili pa malo otseguka, makulidwe a gulugufe ndi kukana kokha pamene sing'anga imayenda kupyolera mu thupi la valavu, kotero kuti kutsika kwapakati kopangidwa ndi valavu kumakhala kochepa kwambiri, kotero kumakhala ndi makhalidwe abwino oyendetsa. Vavu yagulugufe ili ndi mitundu iwiri yosindikiza, zotanuka zofewa ndi chisindikizo chachitsulo. Vavu yosindikizira yofewa, mphete yosindikizira imatha kuyikidwa pathupi la valve kapena kumangirizidwa m'mphepete mwa mbale yagulugufe.

Mavavu okhala ndi zisindikizo zachitsulo nthawi zambiri amakhala ndi moyo wautali kuposa omwe amakhala ndi zisindikizo zotanuka, koma ndizovuta kuti asindikize kwathunthu. Chisindikizo chachitsulo chimatha kutengera kutentha kwambiri kogwira ntchito, pomwe zotanuka zofewa zimakhala ndi vuto lochepa chifukwa cha kutentha.

Ngati valavu ya butterfly ikufunika kuti igwiritsidwe ntchito poyendetsa kayendetsedwe kake, chinthu chachikulu ndikusankha bwino kukula ndi mtundu wa valve. Kapangidwe ka valavu ya butterfly ndiyoyenera kupanga mavavu akulu akulu. Vavu yamtunduwu iyenera kuyikidwa mopingasa mu payipi.

Mavavu agulugufe omwe amagwiritsidwa ntchito nthawi zambiri amaphatikiza ma valve agulugufe wafewa ndi ma valve agulugufe wa flange. Vavu yagulugufe yamtundu wa wafer imalumikiza valavu pakati pa mapaipi awiri okhala ndi mabawuti. Valavu ya butterfly yamtundu wa flange imakhala ndi ma flanges pa valavu, ndipo ma flanges pa malekezero onse a valavu amalumikizidwa ndi ma flanges a chitoliro ndi mabawuti.

cholinga

Amagwiritsidwa ntchito popanga mapaipi amafuta m'makampani a sulfuric acid: cholowera ndi chowombera kutsogolo kwa ng'anjo, kulowera ndi kutulutsa kwa fan relay, mndandanda wamagetsi amagetsi ndi valavu yolumikizira, polowera ndi kutulutsa kwa S02 chowombera chachikulu, malamulo osinthira, kulowera ndi kutulutsa kwa preheater, etc. ndi kudula gasi.

Amagwiritsidwa ntchito poyaka sulfure, kutembenuka ndi magawo owuma a sulfur based sulfuric acid production system. Ndilo mtundu woyamba wa mavavu opangira sulfure based sulfuric acid unit. Amaganiziridwa ndi ogwiritsa ntchito ambiri ngati valavu yagulugufe yokhala ndi ntchito yabwino yosindikiza, ntchito yopepuka, dzimbiri m'mbali, kukana kutentha kwambiri, ntchito yabwino, yosinthika, yotetezeka komanso yodalirika, ndipo yalimbikitsidwa kwambiri ndikugwiritsidwa ntchito.

Amagwiritsidwanso ntchito kwambiri mu payipi ya SO2, nthunzi, mpweya, mpweya, ammonia, CO2 mpweya, mafuta, madzi, brine, mowa zamchere, madzi a m'nyanja, asidi nitric, hydrochloric acid, asidi sulfuric, asidi phosphoric ndi TV ena mu mankhwala. , petrochemical, smelting, pharmaceutical, chakudya ndi mafakitale ena monga chipangizo chowongolera ndi choletsa.

Mapangidwe a valve butterfly valve

① Mapangidwe apadera a njira zitatu eccentric samapangitsa kuti pakhale mikangano pakati pa malo osindikizira ndikuwonjezera moyo wautumiki wa valve.

② Chosindikizira chotanuka chimapangidwa ndi torque.

③ Mapangidwe owoneka bwino opangidwa ndi mphero amathandiza kuti valavu ikhale ndi ntchito yosindikiza yokhayokha kuti ikhale yolimba komanso yolimba pamene valavu imatsekedwa, ndipo malo osindikizira amakhala ndi chipukuta misozi ndi kutayikira zero.

④ Kukula kwakung'ono, kulemera kopepuka, ntchito yopepuka komanso kuyika kosavuta.

⑤ Zipangizo zamakina ndi zamagetsi zimatha kukhazikitsidwa molingana ndi zofunikira za ogwiritsa ntchito kuti zikwaniritse zosowa zakutali ndikuwongolera pulogalamu.

⑥ Zida zosinthira zitha kugwiritsidwa ntchito pazofalitsa zosiyanasiyana, ndipo chiwombankhangacho chimatha kukhala anticorrosive (lining F46, gxpp, Po, etc.).

⑦ Kusiyanasiyana kwapang'onopang'ono: matako achitsulo, flange ndi matako kuwotcherera.
