Background technique
In gas-turbine combustion chamber component test, for carrying out the detailed measurements of outlet parameter, often needing test sensor to be in place on moving mechanism, by translation or the revolution of displacement mechanism, realizing the detailed scanning to pelvic outlet plane.Owing to being high-temperature high-pressure fuel gas in combustor test pipeline, for ensureing displacement mechanism reliable operation, the actuator of displacement mechanism is generally placed in test pipe outside, and this proposes very high requirement to the sealing between displacement mechanism and gas pipeline.Traditional sealing means is comparatively complicated, dismounting difficulty, and sealing effect is unstable.
Summary of the invention
The purpose of this utility model is to provide the seal arrangement of a kind of firing chamber test bit moving mechanism, and to solve, traditional sealing device structure is complicated, dismounting is difficult and the problem of sealing effect instability.
The technical solution of the utility model is:
A seal arrangement for firing chamber test bit moving mechanism, comprises gas pipeline, the fitting seat being with plenum, displacement mechanism and high-pressure air feed pipeline;
Described fitting seat is fixedly mounted on the tube wall aperture position place of described gas pipeline, and institute's displacement mechanism is through described plenum;
Spielpassung between institute's displacement mechanism and described fitting seat, described fitting seat is connected with the high-pressure air feed pipeline be communicated with described plenum, and described plenum internal pressure is higher than the gaseous-pressure in described gas pipeline.
Alternatively, the bottom of described fitting seat offers the through hole be communicated with described plenum, and described high-pressure air feed pipeline is connected with described through hole.
Alternatively, described fitting seat and described gas pipeline are bolted to connection.
The beneficial effects of the utility model:
The seal arrangement of firing chamber of the present utility model test bit moving mechanism, structure is simple, easy accessibility, plenum and high-pressure air feed pipeline are set between displacement mechanism and gas pipeline, ensure that plenum pressure is greater than gas pipeline internal pressure, make high-pressure air flow into gas pipeline, effectively can prevent the leakage of high-temperature high-pressure fuel gas.
Accompanying drawing explanation
Accompanying drawing to be herein merged in specification and to form the part of this specification, shows and meets embodiment of the present utility model, and is used from specification one and explains principle of the present utility model.
Fig. 1 is the structural representation of the seal arrangement of the utility model firing chamber test bit moving mechanism.
Embodiment
Here will be described exemplary embodiment in detail, its sample table shows in the accompanying drawings.When description below relates to accompanying drawing, unless otherwise indicated, the same numbers in different accompanying drawing represents same or analogous key element.
As shown in Figure 1, the seal arrangement of a kind of firing chamber of the present utility model test bit moving mechanism, comprises gas pipeline 1, the fitting seat 2 being with plenum 21, displacement mechanism 3 and high-pressure air feed pipeline 4.
Gas pipeline 1 cross section is circular, and the bigger mounting plane of its tube wall thickness setting, mounting plane offers opening, and mounting plane periphery arranges screw hole.
Be provided with inner chamber in fitting seat 2, as plenum 21, fitting seat 2 cavity two ends arrange equal diameter circular hole, and cavity two ends circular hole keeps coaxial with fitting seat 2; Fitting seat 2 periphery is provided with the screw hole matched with the screw hole on gas pipeline 1 mounting plane, and is bolted, and to realize the connection of fitting seat 2 and gas pipeline 1, and joint can adopt the mode encapsulation process such as sealing gasket.
Displacement mechanism 3 is in shaft-like, and lever arm is circular, and lever arm diameter is slightly less than the diameter of the cavity two ends circular hole of band fitting seat 2, and Spielpassung is arranged in two circular holes, and can move back and forth in two circular holes; In addition, displacement mechanism 3 is provided with one end of sensor through plenum 21, extend in gas pipeline 1.
Fitting seat 2 is offered and puts bleed hole, bleed hole is connected with the high-pressure air feed pipeline 4 be communicated with plenum 21, high-pressure air feed pipeline 4 is connected with source of the gas (not shown), makes plenum 21 internal pressure all the time higher than the gaseous-pressure in gas pipeline 1.
When the seal arrangement of firing chamber of the present utility model test bit moving mechanism is installed, first by the circular hole of the lever arm of displacement mechanism 3 through fitting seat 2 two ends, then band fitting seat 2 is installed to the opening of gas pipeline by screw.In work, high-pressure air feed pipeline 4 pairs of plenums 21 are for high-pressure air, plenum 21 internal pressure, higher than the gaseous-pressure in gas pipeline 1, makes high-pressure air by the unidirectional inflow gas pipeline 1 in the gap between displacement mechanism 3 and fitting seat 2, thus prevents the leakage of high-temperature fuel gas.
The seal arrangement of firing chamber of the present utility model test bit moving mechanism, structure is simple, easy accessibility, plenum 21 and high-pressure air feed pipeline 4 are set between displacement mechanism and gas pipeline, ensure that plenum 21 pressure is greater than gas pipeline 1 internal pressure, make high-pressure air flow into gas pipeline 1, effectively can prevent the leakage of high-temperature high-pressure fuel gas.
In the seal arrangement of firing chamber of the present utility model test bit moving mechanism, the bottom of fitting seat 2 offers the through hole be communicated with plenum 21, and high-pressure air feed pipeline 4 is connected with through hole.And fitting seat 2 and gas pipeline 1 are bolted to connection.
The above; be only embodiment of the present utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of described claim.
