Power Station Steam Ball Valve (Chigawo chimodzi)
Mawonekedwe
1. 1/4 kuzungulira kumachepetsa kwambiri kuvala ndi kukangana kwa kulongedza kuti asatayike.
2. Mapangidwe a mpira wa anti scour amatsimikizira kuti malo otsegulira ndi aakulu pa digiri yotsegulira yofanana pa gawo loyambirira la kusintha, amachepetsa kuthamanga kwa kusiyana mofulumira, amachepetsa nthawi yowonongeka ya kupanikizika kosiyana, ndikuwonjezera bwino moyo wautumiki.
3. The graphite kulongedza ndi mpando kusintha Alamu zisanayambe zomangika ndi gulugufe kasupe kupewa kutseka pansi kutentha kwambiri.
4. Pansi pazikhalidwe zina zapadera zogwirira ntchito (monga valavu ya chitoliro chachikulu cha nthunzi, chomwe chimapangitsanso kutuluka kwa nthunzi kuchokera pachitoliro cha kutentha koyambira kuwonjezera pa ngalande), chifukwa cha kuthamanga kwakukulu ndi mphamvu yaikulu yamphamvu. , mpira womwe uli pabowo la ceramic umatulutsa kugwedezeka kwakanthawi kobwerezabwereza kuti kukhudze ndodo ya valve.Torque imakula kwambiri, zomwe zimakhala zosavuta kupangitsa ndodo yosinthira kusweka ndi kupotoza, zomwe zimapangitsa kuti zisagwiritsidwe ntchito moyenera.The throttling orifice ntchito kwa decentralized kusintha mphamvu pamene valavu anatsegula pa chiyambi kuchepetsa kukokoloka ndi cavitation.
5. Zambiri zokongola ndi mapangidwe ophatikizika.

5. Kulumikizana ndi kusokoneza chivundikiro cha bolt ndi chosavuta, ndipo zowonjezera zimatha kusinthidwa ndikukonza tsiku ndi tsiku kungapangitse moyo wautumiki.
Mapulogalamu:
Kuwongolera ndi kuthamanga kwa turbine bypass bypass ndi nthunzi yotentha kwambiri.Kuwongolera nthunzi ndi kutenthetsa mapaipi a malata a ng'anjo yowomba mwaye.Kuwongolera kuthamanga kwa nthunzi wapaipi yotentha kwambiri komanso yothamanga kwambiri.
