Mavavu agulugufe atatu amatha kugwiritsidwa ntchito kumalo ogwirira ntchito ndi kutentha mpaka 600 ° C, ndipo kutentha kwa valavu nthawi zambiri kumagwirizana ndi zinthu ndi kapangidwe.

Pamene kutentha kwa valavu kupitirira 350 ℃, zida za nyongolotsi zimakhala zotentha chifukwa cha kutentha, zomwe zimawotcha mosavuta chowotcha chamagetsi, ndipo nthawi yomweyo zimachititsa kuti woyendetsa aziwotcha mosavuta.Chifukwa chake, pamapangidwe anthawi zonse a NSEN, tsinde lokulitsa lomwe lili ndi mawonekedwe oziziritsa a zipsepse amagwiritsidwa ntchito kuteteza ma actuators monga zida zamagetsi ndi pneumatics.

Nachi chitsanzo chosavuta.Pamene thupi lalikulu lakuthupi liri losiyana ndipo ziwalo zamkati zimakhala zofanana, kutalika kwa tsinde la valve yowonjezera nthawi zambiri kumakhala kosiyana pansi pa kutentha komweko kwa ntchito.

Pamene mtundu kugwirizana ndi flange, m'pofunika kulabadira kwambiri kutentha kwambiri 538 ℃.Sitikulimbikitsidwa kugwiritsa ntchito kugwirizana kwa flange pamene kutentha kwenikweni kumadutsa 538 ℃.

Chithunzi chotsatirachi chikuwonetsa valavu yathu yamtundu wamtundu wa kaboni chitsulo chowonjezera kutentha kwa gulugufe, zida zake ndi izi:

Mavavu thupi-WCB

Vavu disc-WCB

Phokoso la mphete-SS304

Chisindikizo- SS304+Graphite

Mtengo wa 2CR13

Kutentha kwakukulu kwa valve ndi 425 ℃
