Mfundo ntchito ndi kumanga ndi unsembe mfundo mphira akukhala gulugufe valavu

Themphira wokhala ndi butterfly valvendi mtundu wa valavu yomwe imagwiritsa ntchito mbale yagulugufe yozungulira ngati gawo lotsegula ndi lotseka ndikuzungulira ndi tsinde la valve kuti litsegule, kutseka ndi kusintha njira yamadzimadzi. Gulugufe mbale wamphira wokhala ndi butterfly valveimayikidwa m'mimba mwake ya payipi. Mu njira ya cylindrical yamphira wokhala ndi butterfly valvethupi, mbale yagulugufe yooneka ngati chimbale imazungulira mozungulira, ndipo ngodya yozungulira imakhala pakati pa 0 ° ndi 90 °. Ikazungulira mpaka 90 °, valavu imatsegulidwa kwathunthu.

Zomanga ndi kukhazikitsa

1. Malo oyika, kutalika, ndi njira yotumizira ndi kutumiza kunja ziyenera kukwaniritsa zofunikira za mapangidwe, ndipo kugwirizana kuyenera kukhala kolimba ndi kolimba.

2. Pamitundu yonse ya mavavu apamanja omwe amaikidwa papaipi yotsekera matenthedwe, chogwiriracho sichiyenera kutsika.

3. Kuyang'ana kowonekera kuyenera kuchitidwa valve isanakhazikitsidwe, ndipo dzina la valve liyenera kukwaniritsa zofunikira za "General Valve Mark" GB12220. Kwa valavu yomwe mphamvu yake yogwira ntchito ndi yaikulu kuposa 1.0MPa ndipo imagwira ntchito yodula chitoliro chachikulu, mphamvu ndi kuyesedwa kolimba ziyenera kuchitidwa musanayike, ndipo zimaloledwa kugwiritsidwa ntchito pambuyo poyesa mayeso. Pakuyezetsa mphamvu, kupanikizika kwa mayeso ndi 1.5 kuwirikiza mwadzina, ndipo nthawiyo siichepera mphindi 5. Nyumba ya valve ndi kulongedza ziyenera kukhala zoyenerera popanda kutayikira. Pakuyesa kolimba, kukakamiza kwa mayeso ndi 1.1 nthawi yanthawi yopumira; kukakamizidwa kwa mayeso kuyenera kukwaniritsa zofunikira za GB50243 nthawi yoyeserera, ndipo valavu yosindikizira disc ndiyoyenera ngati palibe kutayikira.

Zosankha zamalonda

1. The waukulu ulamuliro magawo amphira wokhala ndi butterfly valvendi mafotokozedwe ndi miyeso.

2. Ikhoza kugwiritsidwa ntchito pamanja, pamagetsi kapena ndi zipper, ndipo ikhoza kukhazikitsidwa pamakona aliwonse mkati mwa 90 °.

3. Chifukwa cha shaft imodzi ndi mbale imodzi ya valve, mphamvu yobereka imakhala yochepa, ndipo moyo wautumiki wa valve ndi waufupi pansi pa kusiyana kwakukulu kwapakati ndi kuthamanga kwakukulu.
