Description
Technical field
The present invention relates to seal for pipe joints equipment technical field, 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.
The content of the invention
It is an object of the invention to provide a kind of jet chimney sealing device, is asked with solve to propose in above-mentioned background technology
Topic.
To achieve the above object, the present invention provides following technical scheme：A kind of jet chimney sealing device, including flange
Disk, there are spacer layer and high temperature resistant castable, the ring flange is separately positioned on the first jet chimney and the second jet chimney port
Place, is provided with buffer interface, and the first jet chimney and the second steam pipe between first jet chimney and the second jet chimney
Road is separately fixed at annular groove both sides, and the ring slot outside is connected with projection, and projection periphery setting is fluted, described recessed
High temperature resistant castable is filled with groove, is provided with stator on the inside of the annular groove, the stator inwall is provided with spacer layer, institute
State and Graphite pad is fixed among spacer layer, be connected with polyethylene board on the outside of the Graphite pad, on second jet chimney
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 invention are as follows：
1st, the spacer layer of the invention by setting, polyethylene board add adhesive force of the Graphite pad in seal process, due to
It has good heat resistance and cold resistance, and 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 use of at high operating temperatures, together
When be easily changed dismounting, it is durable in use.
2nd, the present invention passes through the high temperature resistant castable and groove of setting so that the first jet chimney and the second jet chimney with
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 projection.
3rd, the present invention is easy to Graphite pad and polyethylene board to be fitted tightly over the first jet chimney by the stator of setting
With the inwall of the second jet chimney, good sealing effect.

Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other under the premise of creative work is not made
Embodiment, belong to the scope of protection of the invention.
Fig. 1-3 are referred to, the present invention provides a kind of technical scheme：A kind of jet chimney sealing device, including ring flange 1,
There are spacer layer 3 and high temperature resistant castable 9, the ring flange 1 is separately positioned on the first jet chimney 5 and the end of the second jet chimney 8
At mouthful, buffer interface 2, and the first jet chimney 5 and second are provided between the jet chimney 8 of the first jet chimney 5 and second
Jet chimney 8 is separately fixed at the both sides of annular groove 12, and the outside of annular groove 12 is connected with projection 13, and the periphery of projection 13 is set
Groove 10 is equipped with, high temperature resistant castable 9 is filled with the groove 10, the inner side of annular groove 12 is provided with stator 11, described
The inwall of stator 11 is provided with spacer layer 3, and Graphite pad 14, the outside of Graphite pad 14 are fixed among the spacer layer 3
Polyethylene board 15 is connected with, valve 4 is installed on second jet chimney 8, bolt 6, institute are equipped between the ring flange 1
State the one end of bolt 6 and be fixedly connected with nut 7, high temperature resistant castable 9 and groove 10 cause the first jet chimney 5 and the second steam pipe
