Ubwino wa wafer check valve ndi chiyani?

Valavu yoyang'ana Wafer ili ndi kutalika kwa ma valve afupiafupi, kukula kochepa komanso kulemera kopepuka. kutseka ma valve othamanga, kuthamanga kwa nyundo yamadzi otsika, njira yoyenda bwino, kukana kwamadzimadzi otsika. mapaipi opingasa kapena oyima angagwiritsidwe ntchito. Ndiosavuta kukhazikitsa, kuchitapo kanthu movutikira, ntchito yabwino yosindikiza, kugunda kwa valve yaying'ono, mphamvu yaying'ono ya valavu, mawonekedwe osavuta, mawonekedwe okongola, moyo wautali wautumiki, kudalirika kwakukulu. Zimalepheretsa kubweza kwapakati / kubwerera kumbuyo, kuwongolera zokha pakutsegula ndi kutseka ndi zina zotero.

Valavu yoyang'ana wafer imagwiritsidwa ntchito makamaka mu petrochemical, chitsulo ndi zitsulo zachitsulo, mphamvu yamagetsi ndi mafakitale ena, m'matauni ndi okwera m'manyumba opangira madzi ndi ma network. Chifukwa kutalika kwa mawonekedwe a valavu yolumikizira kulumikizana ndiafupi kuposa valavu yachikhalidwe yolumikizira flange. Ndiwoyenera kwambiri malo okhala ndi malire a unsembe.

Kodi muyenera kulabadira chiyani mukakhazikitsa valve yowunikira?

1. Sichiloledwa kuyika valavu pa mawonekedwe a pampu ya flange, ndipo tikulimbikitsidwa kuti muyike valve osachepera nthawi 10 kutalika kwa dzina lachidziwitso (DN) 2 mamita kunja kwa malo okhazikika.

2. Poika valavu, tikulimbikitsidwa kugwiritsa ntchito gasket lathyathyathya kuti mudziwe kusindikiza.

3. Mapaipi okhala ndi khoma la makulidwe oposa 10 saloledwa. 4.

4. Yoyenera kuyika yopingasa kapena yowongoka, kuyika koyima kumangolola kuwongolera kwamadzi mmwamba.

5. Ikani valavu pakati pa ma flanges (axis alignment) ndikuyika torque yovomerezeka kuti mumangitse ma flanges onse.
