Kusiyana ndi kugwiritsa ntchito mavavu agulugufe wapawiri komanso katatu

Mavavu agulugufe omwe ali ndi ma eccentric ndi ma valve agulugufe atatu amagwiritsidwa ntchito kwambiri m'mafakitale. Amagwira ntchito yofunika kwambiri pakuwongolera madzimadzi ndipo amagwiritsidwa ntchito m'mafakitale osiyanasiyana monga mafuta, mankhwala, kukonza chakudya, ndi kuthira madzi. Kudziwa kusiyana pakati pawo ndikofunikira pakusankha koyenera komanso kugwiritsa ntchito valve yoyenera.

Kusiyana kwa kapangidwe kake: Mapangidwe a valavu yagulugufe yapawiri yophatikizika amaphatikizanso mitsinje iwiri, imodzi yomwe ili pakatikati pa mbale yagulugufe ndipo inayo ili m'mphepete mwa mbale yagulugufe. Kapangidwe kameneka kamathandizira gulugufe kuchepetsa kukangana potsegula ndi kutseka, potero kuchepetsa mphamvu yogwiritsira ntchito. Mosiyana ndi zimenezi, mapangidwe a gulugufe wamtundu wa katatu amawonjezera shaft yachitatu ku mbale ya butterfly, kotero kuti mbale ya butterfly imatha kupatulidwa kotheratu ndi mphete yapampando ikatsekedwa, potero kuchepetsa kusindikiza kusindikiza ndikuwongolera ntchito yosindikiza.

Kusiyana kwa mfundo zogwirira ntchito: Vavu yagulugufe wapawiri wooneka ngati eccentric amawongolera kutuluka kwa madzimadzi pozungulira mbale ya gulugufe. Pamene mbale ya gulugufe yatsegulidwa mokwanira, njira yaikulu imapangidwa pakati pa mbale ya butterfly ndi mphete ya mpando, kotero kuti madziwo amatha kudutsa bwino. M'malo mwake, mbale yagulugufe ikatsekedwa, njirayo idzatsekedwa kwathunthu, kulepheretsa kutuluka kwamadzimadzi.

Mfundo yogwira ntchito ya katatu eccentric butterfly valve ndi yofanana ndi ya double eccentric butterfly valve, koma imasintha malo a gulugufe kupyola muzitsulo zamtundu wa gulugufe kuti athe kudzipatula pampando pamene ali. chatsekedwa. Kapangidwe kameneka kamatha kuchepetsa kuvala kwa malo osindikizira, kutalikitsa moyo wautumiki wa valavu, komanso kupititsa patsogolo ntchito ya kusindikiza ndi kuthamanga kwambiri. control mapulogalamu. Mapangidwe ake ophweka ndi ntchito yosinthika ndi yoyenera pazochitika zomwe zimafuna kutsegula ndi kutseka pafupipafupi. Mwachitsanzo, valavu imagwiritsidwa ntchito nthawi zambiri m'makina operekera madzi ndi ngalande, kuyeretsa madzi owonongeka ndi makina oyendetsa mpweya, ndi zina zotero.

Mosiyana ndi izi, valavu yagulugufe katatu ndi yoyenera kukakamiza kwambiri komanso malo ovuta kwambiri ogwirira ntchito. Chifukwa cha kukhathamiritsa kwake kusindikiza komanso kukana kupanikizika kwambiri, nthawi zambiri amagwiritsidwa ntchito popanga mafuta, makampani opanga mankhwala, gasi wachilengedwe komanso kupanga mphamvu zamagetsi. Kuphatikiza apo, valavu yagulugufe yamitundu itatu ndiyoyeneranso kuyang'anira media zowononga komanso kutentha kwambiri.

Kutsiliza: Pali kusiyana kodziwikiratu pakati pa valavu yagulugufe yawiri eccentric ndi valavu yagulugufe katatu pamapangidwe apangidwe, mfundo zogwirira ntchito komanso momwe amagwiritsidwira ntchito. Ma valve agulugufe omwe ali ndi ma eccentric ndi oyenera kukakamiza kwapakatikati ndi kutsika komanso kuwongolera madzimadzi, pomwe mavavu agulugufe atatu ndi oyenera kupanikizika kwambiri komanso ntchito zovuta kwambiri. Kusankhidwa koyenera ndi kugwiritsa ntchito ma valve oyenerera ndizofunikira kuti zitsimikizidwe kuti zikugwira ntchito bwino ndi chitetezo cha dongosolo. Choncho, muzogwiritsira ntchito, ndizofunikira kwambiri kusankha mtundu wa valve woyenera kwambiri malinga ndi zosowa zenizeni ndi ntchito.
