Kusiyana Pakati pa Resilient Seated Butterfly Valve ndi Metal Seated Butterfly Valve
Mavavu agulugufe, ali ndi kapangidwe kakang'ono, kapangidwe kosavuta, kachitidwe kabwino, komanso kukonza kosavuta.
Iwo ndi amodzi mwa ma valve odziwika kwambiri a mafakitale.
Nthawi zambiri timakhala ndi mavavu agulugufe okhala ndi mphira, kapena ma valve agulugufe okhala ndi mphira. M'gululi, tili ndi ma valve agulugufe okhala ndi mphira, ma valve agulugufe okhala ndi mphira, ma valve agulugufe amtundu wa U ndi ma valve agulugufe awiri.
Potsegula ndi kutseka, valavu ya mpira imagwira ntchito pansi pa mphamvu ya mipando ya valve pamapeto onse awiri.Poyerekeza ndi valavu ya theka-mpira, valavu ya mpira imakhala ndi torque yayikulu yotsegulira ndi kutseka.Ndipo kukula kwake kwadzina, kumawonekeranso kusiyana kwa kutsegula ndi kutseka torque.Kutsegula ndi kutseka kwa valavu ya butterfly kumazindikiridwa ndi kugonjetsa kusinthika kwa mphira.Komabe, zimatenga nthawi yayitali kugwiritsa ntchito mavavu a pachipata ndi ma valve a globe ndipo ndizovuta kuchita izi.
Vavu ya mpira ndi valavu yamapulagi ndi amtundu womwewo.valavu ya mpira yokhayo ili ndi mpira wopanda dzenje wowongolera kuyenda modutsamo.Mavavu a mpira amagwiritsidwa ntchito kwambiri kudula, kugawa ndikusintha njira yoyendetsera sing'anga mumapaipi.
Valovu yagulugufe wa katatu
Malo onse osindikizira a valve ndi zitsulo kapena zinthu zina zolimba, zomwe sizimasindikiza bwino, koma zimakhala ndi makina abwino, monga kukhala osagwirizana ndi kutentha kwambiri komanso anti-kuvala.
Nthawi zambiri, pali kusiyana kotere kwa mavavu agulugufe amipando iwiri yosiyana.
<1> Mapangidwe Osiyana
Kapangidwe ka mzere wapakati wa valavu yagulugufe wokhala mokhazikika pomwe kapangidwe kaŵirikaŵiri kapena katatu ka valavu yagulugufe yokhala ndi zitsulo.
<2> Kutentha kosiyana koyenera
timagwiritsa ntchito valavu yagulugufe yokhazikika pa kutentha kwabwino, pomwe valavu yagulugufe yokhala ndi Zitsulo imagwiritsidwa ntchito potsika, mwachizolowezi komanso kutentha kwambiri.
<3> Kupanikizika kosiyana
Vavu yagulugufe yokhala pansi ndi yoyenera kutsika komanso kutsika kwabwinobwino ndipo valavu yagulugufe yokhala ndi Metal imathanso kugwirizana ndi kuthamanga kwapakati.
<4> Kusindikiza kosiyana kosiyana
Vavu yagulugufe yokhala pansi komanso valavu yagulugufe yokhala ndi Metal imakhala ndi ntchito yabwino yosindikiza.Pambuyo pake imatha kusindikiza bwino pakuthamanga kwambiri komanso kutentha.
