Vavu ya butterfly mu kapangidwe ka kalasi yofewa komanso kuyambitsa magwiridwe antchito

Vavu agulugufe chimagwiritsidwa ntchito m'matauni zomangamanga, petrochemical, zitsulo, mphamvu yamagetsi ndi mafakitale ena mu payipi sing'anga kuchita kudula kapena kusintha otaya chipangizo bwino. Kapangidwe ka ma valve a butterfly ndiye njira yabwino kwambiri yotsegulira ndi kutseka paipi, ndiye njira yoyendetsera mapaipi amasiku ano otsegulira ndi kutseka. Nthawi zambiri timakhala ndi valavu yagulugufe yamtundu wofewa, yomwe imagwiritsidwa ntchito kwambiri pakutentha kwabwino, kutsika kwapang'onopang'ono komwe kumagwirira ntchito, monga madzi ndi ngalande, ntchito zosungira madzi, zomangamanga zamatauni ndi madera ena. Zotsatirazi makamaka zimabweretsa valavu imodzi yokha yagulugufe, valavu yagulugufe wapawiri komanso ma valve agulugufe atatu.

Choyamba, imodzi eccentric dongosolo lavalavu yagulugufe yofewa, mpando kusindikiza mtanda gawo kapena gulugufe mbale makulidwe a malangizo a mzere equidistant ndi pakati kasinthasintha wa valavu tsinde wachibale eccentric, kuti valavu gulugufe m'kati kutsegula, gulugufe mbale kusindikiza pamwamba pang'onopang'ono kutali valavu mpando kusindikiza pamwamba. Gulugufe mbale kasinthasintha 20 ~ 25 °, gulugufe mbale kusindikiza pamwamba olekanitsidwa ndi valavu mpando kusindikiza pamwamba, kuti valavu gulugufe mu ndondomeko kutsegula, wachibale mawotchi kuvala ndi extrusion pakati pa malo awiri osindikiza kwambiri yafupika, kotero kuti gulugufe valavu kusindikiza ntchito akhoza bwino. Kapangidwe kameneka kamadalira kwambiri kusinthika kwa zotanuka komwe kumapangidwa ndi kutulutsa pakati pa mbale yagulugufe ndi mpando wa valavu kuti zitsimikizire kusindikizidwa kwa valavu yagulugufe.

Pamaziko a eccentric gulugufe valavu, pakati kasinthasintha wa gulugufe mbale ndi kuchotsa pakati pa mzere wa valavu otaya njira, amene amapangitsa gulugufe mawonekedwe cam zotsatira pa njira yotsegula, kotero kuti kusindikiza pamwamba pa gulugufe mbale akhoza anasiyanitsidwa ndi kusindikiza pamwamba pa mpando valavu mofulumira kuposa dongosolo limodzi eccentric. Pamene mbale ya gulugufe imazungulira ku 8 ° ~ 12 °, malo osindikizira a gulugufe amasiyanitsidwa ndi kusindikiza pamwamba pa mpando wa valve. Mapangidwe a kamangidwe kameneka amachepetsa kwambiri kuvala kwa makina ndi ma extrusion pakati pa malo awiri osindikizira, zomwe zimapangitsa kuti valavu ya butterfly isindikize bwino.

Ndipo pamaziko avalavu yagulugufe yawiri eccentric, mzere wapakati wa mpando kusindikiza pamwamba ndipamene eccentricity angular ndi mzere wapakati wa valavu, zomwe zimapangitsa kusindikiza pamwamba pa gulugufe mbale yomweyo detach pa mpando kusindikiza pamwamba pa mphindi kutsegula pa ndondomeko ya gulugufe mbale kutsegula, ndi kukhudzana kokha ndi akanikizire mpando kusindikiza pamwamba pa mphindi kutseka. Kuphatikizika kwapadera kumeneku kwa eccentricity kumagwiritsa ntchito mokwanira mphamvu ya cam, kumathetsa mikangano yamakina ndi abrasion pakati pa malo awiri osindikizira a butterfly valve kusindikiza vice pamene valavu imatsegula ndikutseka, ndikuchotsa kuthekera kwa abrasion ndi kutayikira. Chisindikizo chotuluka chimasinthidwa kukhala torque chisindikizo, ndipo kusintha kwa mphamvu yosindikizira kumachitika posintha torque yakunja, kuti ntchito yosindikiza ndi moyo wautumiki wa ma eccentric ma valve agulugufe osindikizidwa bwino kwambiri.

Kupatula apo, Tianjin Tanggu Water Seal Valve Co., Ltd. ndiukadaulo wapamwamba wokhala ndi mphira wokhala valavu yothandizira mabizinesi, zinthuzo ndizokhazikika pampando wagulugufe valavu, valavu yagulugufe, valavu yagulugufe iwiri, valavu yagulugufe, valavu, valavu yapawiri mbale yowunikira,Valve yotulutsa mpweya, Y-Strainer ndi zina zotero. Ku Tianjin Tanggu Water Seal Valve Co., Ltd., timanyadira popereka zinthu zapamwamba zomwe zimakwaniritsa miyezo yapamwamba kwambiri yamakampani. Ndi ma valve athu osiyanasiyana ndi zomangira, mutha kutikhulupirira kuti tikupatsani yankho labwino kwambiri pamadzi anu. Lumikizanani nafe lero kuti mudziwe zambiri zazinthu zathu komanso momwe tingakuthandizireni.
