Vavu ya butterfly ndi ventilation valve yomwe imadutsa mumlengalenga kusuntha mpweya. Kapangidwe kake ndi kosavuta komanso kosavuta kugwiritsa ntchito.

chikhalidwe:

1. Mtengo wa mpweya wa butterfly valve ndi wotsika, teknoloji ndi yosavuta, torque yofunikira ndi yaying'ono, chitsanzo cha actuator ndi chaching'ono, ndipo mtengo wonse udzakhala ndi mwayi waukulu;

2. Kutentha kwenikweni kulibe malire. Zida zosiyanasiyana zingagwiritsidwe ntchito kutentha (<100 ℃), kutentha kwakukulu (200 ℃ + -) ndi kutentha kwakukulu (500 ℃ + -);

3. Moyo wautali wautumiki, mawonekedwe osavuta komanso kukonza kosavuta kwa valavu ya butterfly;

4. Ndi mlingo wina wotuluka, yonjezerani mphete yosungira pakhoma lamkati la thupi la valve kuti mbale ya valve ikhale yogwirizana kwambiri ndi mphete yosungira pamene valavu yatsekedwa kuti muchepetse kutayikira, ndipo kutuluka kungathe kuwongoleredwa pafupifupi 1. %; kwa ntchito yowononga gasi, ili mkati mwazowongolera;

Kutengera izi, valavu ya butterfly yakhala ikudziwika kwambiri, kutulutsa kwa adsorption, kuyaka kothandizira ndi ntchito zina zochizira gasi zinyalala zimagwiritsa ntchito valavu yamtunduwu.

Magulu a valavu ya butterfly ya mpweya wabwino:

1. Malinga ndi kugwirizana, akhoza kugawidwa mu flange, kuwotcherera mapeto ndi yopyapyala malekezero

2 .Malinga ndi zinthu, zikhoza kugawidwa mu zitsulo zosapanga dzimbiri, carbon zitsulo ndi wapawiri gawo zitsulo zitsulo.

3. Malinga ndi njira yogwirira ntchito, imatha kugawidwa kukhala magetsi, manja, pneumatic ndi hydraulic operation.
