Technical field
Seal for pipe joints equipment technical field is the utility model is related to, specially a kind of jet chimney sealing device.
Background technology
The Sealing Technology of vapour system pipeline break-make controlling position is current relevant field urgent problem to be solved, traditional
Control mode typically uses dish-style stop valve.Gap is larger between the flap and valve body of dish-style stop valve, and be prone to wear out and
Get rusty, thus sealing is poor, need to often repair, change, and causes acquisition cost, use cost increase.In addition, existing steam pipe
Road sealing device, the contact surface that valve body coordinates with flap are usually arranged as the larger plane of area, and two rigid planar contacts are close
Envelope, under high temperature, high pressure conditions, easily caused material in waste gas treatment process or impurity are accumulated on this plane, caused
The identical imprecision of contact surface and flap, reduces sealing, another convenience, because medium temperature is high, pressure among jet chimney
Power is big, flow velocity is fast, operationally can bring larger expansive force and impulsive force to the gasket seal in pipeline so that joint
Seal easily aging, it is also more inconvenient often to change, therefore we make improvement to this, proposes a kind of jet chimney sealing
Device.

At mouthful, buffer interface, and the first jet chimney and the second steam are provided between first jet chimney and the second jet chimney
Pipeline is separately fixed at annular groove both sides, and the ring slot outside is connected with projection, and projection periphery setting is fluted, described
High temperature resistant castable is filled with groove, stator is provided with the inside of the annular groove, the stator inwall is provided with spacer layer,
Graphite pad is fixed among the spacer layer, polyethylene board, second jet chimney are connected with the outside of the Graphite pad
On valve is installed, bolt is equipped between the ring flange, described bolt one end is fixedly connected with nut.
Preferably, be formed in one structure between the stator and annular groove.
Preferably, the stator is stainless steel.
Preferably, the polyethylene board is attached at Graphite pad outer surface, and polyethylene board and Graphite pad are equal in magnitude.
Preferably, it is fixedly connected by welding between the projection and annular groove.
Compared with prior art, the beneficial effects of the utility model are：
1st, the utility model adds attachment of the Graphite pad in seal process by the spacer layer of setting, polyethylene board
Power, because it has good heat resistance and cold resistance, chemical stability is good, while because its density is low, has good rigidity
And toughness, high mechanical strength, the sealing effectiveness of jet chimney flange joint is enhanced, can be long-term at high operating temperatures
Use, while be easily changed dismounting, it is durable in use.
2nd, the high temperature resistant castable and groove that the utility model passes through setting so that the first jet chimney and the second steam pipe
An entirety, the shortcomings that overcoming anti-expansive force and the anti-impact force difference of existing high-temperature resistant sealing pad are formed between road and projection.
3rd, the utility model is easy to Graphite pad and polyethylene board to be fitted tightly over the first steam by the stator of setting
The inwall of pipeline and the second jet chimney, good sealing effect.
