Kusiyana pakati pa parallel gate valve ndi wedge gate valve

Kodi valavu yachipata chofananira ndi chiyani: ndiko kuti, malo osindikizira amafanana ndi mzere wapakati, kotero thupi la valve ndi malo osindikizira pachipata amakhalanso ofanana.Mtundu wodziwika kwambiri wamtunduwu wa valve yachipata ndi mtundu wa zipata ziwiri.Pofuna kupanga thupi la valve ndi malo awiri osindikizira a pachipata kuti agwirizane kwambiri pamene akutseka, kagawo kakang'ono kaŵirikaŵiri kaŵirikaŵiri kamakhala pakati pa zipata ziwirizo.Mwa njira iyi, pamene valavu yatsekedwa, kukhudzana pakati pa mbali ziwiri zowonongeka kwazitsulo ndi pansi pa thupi la valve kumatsindika pang'onopang'ono, ndipo chipata chachiŵiri chimakankhidwa kuti chitsegulidwe kuti chisindikizo cha chitseko ndi valve. matupi amasindikizidwa ndi kumangirizidwa mwamphamvu.Mtundu uwu wa zipata ziwiri zofananira zimagwiritsidwa ntchito kwambiri pamapaipi otsika kwambiri monga mapaipi ang'onoang'ono.Ma valve ofananira ndi chipata chimodzi amapezekanso koma osowa.

Chipata cha Wedge chili ndi zipata ziwiri komanso zipata.Ubwino wa mtundu wa zipata ziwiri ndikuti kulondola kwa kusindikiza ndi ngodya kumakhala kotsika, kusintha kwa kutentha sikuli kophweka kuti pakhale mphero yachipata, ndipo gasket ikhoza kuwonjezeredwa kuti iwononge kuvala kwa kusindikiza pamwamba.Choyipa ndichakuti mawonekedwewo ndi ovuta, ndipo ndi osavuta kumamatira mu sing'anga youma, ndipo koposa zonse, mbale ya pachipata imakhala yosavuta kugwa pambuyo poti ma baffles apamwamba ndi apansi akuwonongeka kwa zaka zambiri.Ngakhale kuti chipata chimodzi chili ndi kuipa kwa kusindikiza kwakukulu ndi kulondola kwakukulu kwa angular, kukonza kovuta, ndi kusintha kwa kutentha kungapangitse kuti chipatacho chikhale chophwanyika, ndi chosavuta komanso chodalirika chogwiritsidwa ntchito.Elastic deformation imagwiritsidwa ntchito kubweza kupatuka komwe kumapangidwa pamakona osindikizira, kotero kumagwiritsidwa ntchito kwambiri pakadali pano.
