Platform and lower convex platform；When valve is closed, the front face of convex platform and valve page, the rear-face contact of lower convex platform and valve page.
Sealing gasket is provided between boss and valve page.
The thickness that boss stretches out heat-insulation layer is more than 10mm；
Gap between heat-insulation layer inwall and valve page is 5-20mm；
Also include the actuator for being connected to axle power intake.
Horizontal range between convex platform and lower convex platform is equal with valve page thickness.
Two opposite faces of valve buckle are provided with support base, and the bearing for support shaft is provided with support base.
Heat-insulation layer is high temperature resistant castable or heat-preservation cotton.
Square with the axis reinforcement is provided with valve page.
Compared with prior art, the present invention at least has the advantages that：Heat-insulation layer is provided with valve buckle, in heat-insulation layer
Valve page is set, gap is provided between heat-insulation layer inwall and valve page, axle is connected through valve buckle with valve page fixing, avoids valve page in height
It is stuck when warm deformation, it is ensured that valve execution action is smooth；Heat-insulation layer inwall is provided with boss, and boss is divided into by boundary of axle
Boss and lower convex platform；When valve is closed, the front face of convex platform and valve page, the back side of lower convex platform and valve page connects
Touch, be in close contact between valve page and boss, seal form is changed into end face seal, avoid gas from leaking, significantly reduce height
The released gas rate of warm valve, by using said structure design, in the production process of reality, set between valve page and heat-insulation layer
Gap when, without consider further that valve page expansion when need with being bonded between heat-insulation layer inwall the problem of, reduce design and manufacture
Difficulty, improves yields, and the equipment of production has high job stability.
Further, sealing gasket is set to strengthen sealing effectiveness between boss and valve page.
Further, the thickness of boss stretching heat-insulation layer is more than 10mm, makes have enough contact surfaces between boss and valve page
Product, avoids boss by conquassation, while ensure sealing effectiveness.
Further, the gap between heat-insulation layer inwall and valve page is 5-20mm, valve page is gone back in the case of thermal deformation
It can rotate freely.
Further, the horizontal range between convex platform and lower convex platform is equal with valve page thickness, it is ensured that valve is when closed
Valve page is in vertical state.
Further, high temperature resistant castable or heat-preservation cotton are conventional insulation material, are adapted to do the heat-insulation layer in high-temperature valve,
It is readily available, and cost is low.
Further, square with the axis reinforcement is provided with valve page, improves valve page intensity, can effectively reduce the thickness of valve page
Degree, save raw material.
