Vavu Yoyandama ya Mpira Wapaipi ya Gasi

Nambala ya Model:

Kufotokozera Kwachidule:

GDF-5 valavu ya mpira ndi mtundu wa valavu yoyandama yomwe imalumikizidwa ndi flange. Itha kuyikidwa paokha paipi kuti ingoyang'anira kutulutsa kwa gasi, mafuta ndi njira zina zoyendera; imathanso kukhala ndi mita yolumikizira kuti izindikire kuyeza kwamayendedwe komanso kuwongolera panjira yoyendera mapaipi. Lili ndi makhalidwe a ntchito yodalirika, nthawi yochepa yotsegula ndi yotseka, komanso kupanikizika kwakukulu kwa ntchito. Mosiyana ndi valavu yanthawi zonse yoyandama ya mpira, potulutsira mpweya wa mankhwalawa amatenga njira yopumira ndi ufulu wodziyimira pawokha. Valavu ya mpira yoyandama ya GDF-5 imayendetsedwa ndi injini yaying'ono, ndipo magawo onse amapangidwa motsatira mfundo za dziko.

Ubwino wa Zamalonda

Mawonekedwe a valve ya bomba la gasi ndi zabwino zake
1. Kuthamanga kwa ntchito ndi kwakukulu, ndipo valavu ikhoza kutsegulidwa ndi kutsekedwa mokhazikika mu malo ogwira ntchito a 0.4MPa;
2. Kutsegula kwa valve ndi nthawi yotseka ndi yaifupi, ndipo nthawi yotsegula ndi kutseka valve ndi yocheperapo kapena yofanana ndi 50s pansi pa malire ogwira ntchito 7.2V;
3. Palibe kutayika kwapanikizidwe, ndipo mapangidwe a zero-pressure loss structure ndi ma valve awiri ofanana ndi mapaipi awiri amatengedwa;
4. Ntchito yosindikiza ya valve yotseka ndi yabwino, ndipo chisindikizocho chimapangidwa ndi mphira wa nitrile wokhala ndi kutentha kwakukulu (60 ℃) ndi kutentha kochepa (-25 ℃).
5. Ndi kusintha kwa malire, imatha kuzindikira molondola momwe alili pa malo a valve yosinthira;
6. Valavu yotsekedwa imayenda bwino, popanda kugwedezeka komanso phokoso lochepa;
7. Bokosi la injini ndi gear zimasindikizidwa kwathunthu, ndipo mlingo wa chitetezo ndi ≥IP65, womwe umalepheretsa kuti sing'anga yopatsirana isalowemo, ndipo imakhala ndi ntchito yabwino yoteteza kuphulika;
8. Thupi la valve limapangidwa ndi aluminiyumu, lomwe limatha kupirira kupanikizika kwa 1.6MPa, kukana kugwedezeka ndi kugwedezeka, ndikusintha kumadera ovuta;
9. Pamwamba pa thupi la valve ndi anodized, yomwe imakhala yokongola komanso yoyera komanso imakhala ndi ntchito yabwino yotsutsa-kutu;

Malangizo Ogwiritsa Ntchito

1. Chingwe chofiira ndi waya wakuda ndi mawaya amphamvu, waya wakuda umagwirizanitsidwa ndi electrode yabwino, ndipo waya wofiira amagwirizanitsidwa ndi electrode yolakwika kuti atsegule valve;
2. Mizere yotulutsa chizindikiro cha malo osankhidwa: Mizere yoyera ya 2 ndi mizere yotsegulira ma valve mu malo, yomwe imakhala yochepa kwambiri pamene valve ili; Mizere ya buluu ya 2 ndi mizere ya ma valve yotseka-pamalo, yomwe imakhala yochepa kwambiri pamene valve ili; (Vavu ikatsegulidwa kapena kutsekedwa, magetsi amawonjezedwa kwa 5s kuti atsimikizire kukhazikika kwa chizindikiro chapamalo)
3. Bokosi la deceleration la valve likhoza kusinthidwa madigiri a 180 lonse molingana ndi momwe kasitomala amathandizira kuti akhazikitse bokosi lolamulira, ndipo valve ingagwiritsidwe ntchito kawirikawiri pambuyo pozungulira;
4. Gwiritsani ntchito mabawuti amtundu wa flange kulumikiza mavavu, mapaipi, ndi ma flowmeters. Pamaso unsembe, mapeto nkhope ya flange ayenera kutsukidwa mosamala kupewa chitsulo slag, dzimbiri, fumbi ndi zinthu zina lakuthwa pa mapeto pamwamba kukanda gasket ndi kuchititsa kutayikira;
5. Vavu iyenera kuikidwa mu payipi kapena flowmeter ndi valve yotsekedwa. Ndikoletsedwa kuti mugwiritse ntchito pazovuta kwambiri kapena kutayikira kwa gasi ndikuzindikira kutayikira ndi moto wotseguka;
6. Maonekedwe a mankhwalawa amaperekedwa ndi dzina.
