應(yīng)用:適用于超高溫熔鹽介質(zhì)。
設(shè)計特點:
1:多層密封設(shè)計,確保零泄漏:
第一道密封:波紋管組件密封,采用內(nèi)藏式設(shè)計,免沖刷結(jié)構(gòu),保證使用壽命。
第二道密封:采用超高溫專用低泄露填料(蛭石),完全不受氧化作用影響,更增加了可靠性、安全性以及耐高溫性。
2:閥體閥蓋螺紋連接+焊接,強度密封雙重保證。
3:波紋管選用特材英科鎳625
4:中法蘭采用凹槽設(shè)計,纏繞墊片完全定位,防止墊片擠出損壞。
5:密封面特性:一體式閥座,線密封,整體堆焊硬質(zhì)合金,
錐形閥座,切除結(jié)晶熔鹽。
Application: For ultra-high temperature molten salt media.
Design features:
1: Multi-layer seal design to ensure zero leakage:.
First seal: bellows assembly seal with built-in design and flush-free construction that guarantee the service life.
The second seal: the use of ultra-high temperature special low leakage filler (vermiculite), completely unaffected by oxidation.
This increases reliability, safety and high temperature resistance.
2: Threaded connection of the valve body and cover + welding,
double guarantee of strength and sealing.
3: The bellows is made of special material Inconel 625
4: The middle flange is grooved and the winding gasket is fully
positioned to prevent gasket extrusion damage.
5: Sealing surface characteristics: one-piece valve seat, line sealing,
overall overlay carbide. Conical sealing, removal of crystalline molten salt.
