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 kwa 20 ~ 25 °, gulugufe mbale kusindikiza pamwamba olekanitsidwa kwathunthu ndi valavu mpando kusindikiza pamwamba, kuti valavu gulugufe mu ndondomeko kutsegula, wachibale mawotchi kuvala ndi extrusion pakati pa malo awiri osindikizira kwambiri yafupika, kotero kuti ntchito yosindikiza valavu ya butterfly imatha kuwongoleredwa. 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 valavu yagulugufe imodzi yokha, malo ozungulira a gulugufe amachotsedwa pakati pa mzere wapakati wa valavu, zomwe zimapangitsa kuti gulugufe apange mawonekedwe amtundu wa butterfly panthawi yotsegulira, kotero kuti kusindikiza pamwamba pa mbale ya butterfly kukhoza kupatulidwa. Kusindikiza pamwamba pa mpando wa valve mofulumira kusiyana ndi mawonekedwe a 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 wosindikizira pamwamba umapanga eccentricity ya angular ndi mzere wapakati wa valavu, zomwe zimapangitsa kusindikiza pamwamba pa gulugufe nthawi yomweyo kuchoka pampando wosindikiza pamwamba pa nthawi yotsegula panthawi yotsegulira mbale ya butterfly, ndikungolumikizana ndikusindikiza malo osindikizira mpando panthawi yotseka. 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.
