Abstract
The sealing device of high temperature glasses valve, including valve plate and the extrusome and valve body that contact, T shapes convex surface is set on valve plate, T shapes concave surface is set on extrusome and valve body, the inclined-plane on T shapes convex surface and the inclined-plane of T shapes concave surface abut against, twice metal hard-sealing is formed, soft seal is set at the plane of T shapes concave surface on extrusome and valve body, soft seal forms soft seal together with T shapes convex surface；Further, soft seal is the bellows being fixedly connected and soft graphite ring, and soft graphite ring forms soft seal together with T shapes convex surface.The utility model has the beneficial effects that：1, using the three seal structures of twice inclined-plane sealing soft graphite soft seal with together with firmly, it ensure that the sealing performance of valve；2, worst hot case is may be used at using soft graphite soft seal, it can be with trouble free service under the conditions of 400 800 °C of worst hot case.
Description
Technical field
The utility model is related to a kind of glasses valves, more particularly to a kind of sealing device of glasses valve.
Background technology
Glasses valve is a kind of valve plate mechanism for the form glasses being formed by combining by blind plate, saturating plate, is made along sealing surface of seat
Reciprocating linear moves, and realizes the Special valve for blocking, opening function.This valve is only used in the medium pipeline less than 250 °C.
Due to high temperature（400~800°C）The heatproof of the needs of operating mode, rubber seal is insufficient, it may occur that leakage.Currently, the country has much
Recirculated cooling water can be led to, but ineffective in valve body and extrusome internal recessing in producer, and most multipotency maintains 350 °C of 10 minutes
High temperature.By consulting domestic and international related data, there are no produce can under the conditions of 400 ~ 800 °C of worst hot case trouble free service
Valve.
Invention content
In order to overcome existing glasses valve disadvantages mentioned above, the present invention provide it is a kind of can be in 400-800 °C of worst hot case condition
The sealing device of lower trouble free service.
Technical solution adopted by the utility model to solve its technical problems is the sealing devices of high temperature glasses valve, including valve
Plate and the extrusome and valve body contacted, setting T shapes convex surface on valve plate, setting T shapes concave surface on extrusome and valve body, T shapes
The inclined-plane on convex surface and the inclined-plane of T shapes concave surface abut against, formation twice metal hard-sealing, and T shapes concave surface is flat on extrusome and valve body
Soft seal is set at face, and soft seal forms soft seal together with T shapes convex surface.
Further, soft seal is the bellows being fixedly connected and soft graphite ring, soft graphite ring and T shapes convex surface
Form one of soft seal.
Further, soft graphite ring and the contact surface with T shapes convex surface are curved surface.
The utility model has the beneficial effects that：
1, using the three seal structures of twice inclined-plane sealing soft graphite soft seal with together with firmly, it ensure that the close of valve
Sealing property；
2, it seals the area under equal conditions increasing sealing surface firmly using inclined-plane, reduces leakage, using soft graphite
Soft seal may be used at worst hot case, can be with trouble free service under the conditions of 400-800 °C of worst hot case；
3, the form combined with soft graphite using bellows is worn using the high resiliency of bellows in soft graphite ring
Still compressible sealing surface afterwards, is effectively ensured the leakproofness of valve;
4, soft graphite ring can increase sealing area using curved form, reduce leakage.

Specific implementation mode
As shown in Figure 1, the sealing device of high temperature glasses valve, including valve plate and the extrusome 3 and valve body 1 that contact,
T shapes convex surface A6-1 and T shape convex surface B6-2 is set on valve plate 2, T shapes concave surface A7-1 is set on valve body 1, setting T shapes are recessed on extrusome 3
The inclined-plane of face B7-2, T shape convex surface A6-1 and T shape convex surface B6-2 and the inclined-plane of T shapes concave surface A7-1, T shape concave surface B7-2 abut against,
Twice metal hard-sealing is formed, soft seal is set at the plane of T shapes concave surface A on the T shapes concave surface B7-2 and valve body 1 of extrusome 3
Part, soft seal be with the bellows A4-1 and soft graphite ring A5-1 that are fixedly connected, and be fixedly connected with extrusome 3
Bellows B4-2 and soft graphite ring B5-2, soft graphite ring A5-1 form soft seal together, flexible stone with T shapes convex surface A6-1
Black ring B5-2 forms soft seal together with T shapes convex surface B6-2.Further, soft graphite ring A5-1 and T shapes convex surface A6-1
Contact surface is curved surface, and the contact surface of soft graphite ring B5-2 and T shapes convex surface B6-2 is curved surface.
