Zogulitsa m'makampani aliwonse zimagawidwa molingana ndi ntchito ndi zida zawo, momwemonso ndi makampani opanga ma valve.Mkonzi wamakono akufotokozera makamaka momwe valavu ya mpira imagawidwira.Mavavu a mpira amagawidwa kukhala: valavu yoyandama ya mpira, valavu ya mpira wokhazikika, valavu ya mpira wa orbital, valavu ya V-woboola pakati, valavu ya mpira wanjira zitatu, valavu ya mpira wosapanga dzimbiri, chitsulo chosapanga dzimbiri.Brass Ball Valve Ulusi Wachikazi, valavu yachitsulo yopangira zitsulo, valavu yotulutsa phulusa, valavu ya mpira wa sulfure, valavu ya mpira wa pneumatic, valavu yamagetsi yamagetsi, valavu ya mpira wa ferrule, valavu ya mpira.

Malinga ndi gulu la zipolopolo / zakuthupi, valavu ya mpira imatha kugawidwa kukhala: valavu ya mpira

1. Valavu yachitsulo yachitsulo: monga valavu ya carbon steel, valve yachitsulo, valavu yachitsulo, valavu yachitsulo, titaniyamu alloy valve, Monel valve, copper alloy valve, aluminium alloy valve, lead alloy valve, etc.

2. Mavavu opangidwa ndi zitsulo zazitsulo: monga ma valve opangidwa ndi mphira, ma valve opangidwa ndi fluorine, ma valve otsogolera, ma pulasitiki opangidwa ndi pulasitiki, ndi ma valve opangidwa ndi enamel.

3. Vavu yazinthu zopanda zitsulo: monga valavu ya ceramic, valve ya galasi, valve yapulasitiki.

Pali opanga ambiri apakhomo a mavavu a mpira, ndipo makulidwe ambiri olumikizira si ofanana.Zogawidwa kwambiri m'magulu otsatirawa:

Mpira wa valavu ya mpira ukuyandama.Pansi pa kukakamizidwa kwapakati, mpirawo ukhoza kutulutsa kusuntha kwina ndikukankhira mwamphamvu pamalo osindikizira kumapeto kuti mutsimikizire kusindikiza kotuluka.

Siyanitsani mwadongosolo:

Kusindikiza ndikwabwino, koma katundu wagawo lokhala ndi sing'anga yogwirira ntchito amasamutsidwa ku mphete yosindikiza.Choncho, m'pofunika kuganizira ngati zinthu za mphete yosindikiza zingathe kupirira ntchito yogwira ntchito ya sing'anga.Mukagwidwa ndi kugwedezeka kwakukulu, chigawocho chikhoza kusuntha..Kapangidwe kameneka kamakonda kugwiritsidwa ntchito ngati mavavu apakati komanso otsika.

Mpira wa valavu ya mpira umakhazikika ndipo susuntha mopanikizika.Vavu yokhazikika ya mpira imakhala ndi mpando wa valve woyandama.Pambuyo popanikizidwa ndi sing'anga, mpando wa valve umayenda, kotero kuti mphete yosindikizira imakanizidwa mwamphamvu pa mpira kuti zitsimikizire kusindikiza.Zimbalangondo nthawi zambiri zimayikidwa pazitsulo zapamwamba ndi zapansi ndi mpira, ndipo torque yogwiritsira ntchito ndi yaying'ono, yomwe ili yoyenera kwa ma valve othamanga kwambiri komanso aakulu.

Pofuna kuchepetsa kuthamanga kwa valve ya mpira ndikuwonjezera kudalirika kwa chisindikizo, valavu ya mpira yosindikizidwa ndi mafuta yawonekera, yomwe sikuti imalowetsa mafuta apadera opaka mafuta pakati pa malo osindikizira kuti apange filimu yamafuta, yomwe sikuti imangowonjezera kusindikiza ntchito, komanso kumachepetsa torque yogwiritsira ntchito.Oyenera kuthamanga kwambiri komanso ma valve akulu akulu a mpira.
