Abstract
The utility model discloses a kind of high temperature bushing type auto-compensation pipeline, its structure is: pipeline one end adpting flange is welded to connect compensating jacket, the pipe end of compensating jacket is set to casing flange, and pipeline the other end adpting flange is welded to connect compensation pipeline, compensates pipeline and is inserted in compensating jacket; Be wound with high temperature flexible gasket at compensating jacket and on compensating between pipeline overlap joint circumferential surface, be sleeved on end face that the Gland compensated on pipeline is pressed on high temperature flexible gasket to make at compensating jacket and to compensate to be formed between pipeline and seal; Compensation pipeline is set with sealing gland, spring is set between sealing gland and Gland, by bolt bolt between casing flange, Gland and sealing gland, make spring obtain pretightening force.The utility model unit area compensation rate is large, good seal performance, have automatic-sealed compensate function.
Description
Technical field
The utility model relates to a kind of auto-compensation pipeline, is more particularly for tackling the auto-compensation pipeline producing axial deformation because of thermal expansion.
Background technique
When heating up to prevent high-temperature pipe, producing the problem of axial deformation due to thermal expansion of pipeline, needing to arrange compensator on pipeline, thus the stress reducing tube wall and the active force acted on valve or fixed support.Traditional pipeline compensator has stuffing box packing formula compensator, corrugated expansion joint, square-shaped joints.Stuffing box packing formula compensator easily leaks gas leakage, and need often maintenance and change filler, this can bring certain potential safety hazard to engineering; Corrugated expansion joint cost is higher, and unit area compensation rate is less, limited for installing space and the workplace requiring compensation rate larger is not too applicable; Square pipe compensator boundary dimension is large, installs and takes up room greatly, easily trapped fuel phenomenon occurs, and do not allow under many process conditions.
Summary of the invention
In order to solve the problem, the utility model provides that a kind of unit area compensation rate is large, good seal performance and have that automatic-sealed compensates, high temperature bushing type auto-compensation pipeline safe and reliable to operation.
The utility model is that technical solution problem adopts following technological scheme:
The structural feature of the utility model high temperature bushing type auto-compensation pipeline is: pipeline one end adpting flange is welded to connect compensating jacket, the pipe end of described compensating jacket is set to casing flange, pipeline the other end adpting flange is welded to connect compensation pipeline, and described compensation pipeline is inserted in compensating jacket; High temperature flexible gasket is wound with, to make at described compensating jacket and to compensate to be formed between pipeline and seal on the end face that the Gland be sleeved on described compensation pipeline is pressed on described high temperature flexible gasket at described compensating jacket and on compensating between pipeline overlap joint circumferential surface; Described compensation pipeline is set with sealing gland, spring is set between sealing gland and Gland, by bolt bolt between described casing flange, Gland and sealing gland, make spring obtain pretightening force.
The utility model high temperature bushing type auto-compensation pipeline, its feature is also: described Gland be annular cover plate inner peripheral surface position at one end protruded out pressure cylinder towards described casing flange vertically, be pressed on described pressure cylinder on the end face of described high temperature flexible gasket.
Compared with the prior art, the utility model beneficial effect is embodied in:
1, the utility model installs high-temp and high-strength Compress Spring between Gland and gland flange, it is made to be in compressive state all the time, pretightening force is provided to Gland, automatically Gland is advanced by high-temp and high-strength Compress Spring, ensure that high temperature flexible filler is in compaction state all the time, realize auto-compensation.
2, the utility model adopts single high-temp and high-strength Compress Spring, ensures Gland stress equalization, prevents bias from losing auto-compensation.
3, the utility model can ensure that stuffing box packing is in compaction all the time, ensures compactness, greatly reduces the frequency of maintenance, extends the cycle changing filler, ensures the reliability of seal for pipe joints and reduces management maintenance cost.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Number in the figure: 1a pipeline one end adpting flange, 1b pipeline the other end adpting flange, 2 compensating jackets, 3 high temperature flexible gaskets, 4 bolts, 5 casing flanges, 6 Glands, 7 springs, 8 sealing glands, 9 compensate pipeline.
Embodiment
See Fig. 1, in the present embodiment, the structural type of high temperature bushing type auto-compensation pipeline is: pipeline one end adpting flange 1a is welded to connect compensating jacket 2, the pipe end of compensating jacket 2 is set to casing flange 5, pipeline the other end adpting flange 1b is welded to connect and compensates pipeline 9, compensates pipeline 9 and is inserted in compensating jacket 2; Be wound with high temperature flexible gasket 3 at compensating jacket 2 and on compensating between pipeline 9 overlap joint circumferential surface, be sleeved on end face that the Gland 6 compensated on pipeline 9 is pressed on high temperature flexible gasket 3 to make at compensating jacket 2 and to compensate to be formed between pipeline 9 and seal; Compensation pipeline 9 is set with sealing gland 8, spring 7 is set between sealing gland 8 and Gland 6, by bolt 4 bolt between casing flange 5, Gland 6 and sealing gland 8, makes spring 7 obtain pretightening force.
In concrete enforcement, as shown in Figure 1, Gland 6 has at one end protruded out pressure cylinder towards casing flange 5 vertically on the inner peripheral surface position of annular cover plate, is pressed on the end face of high temperature flexible gasket 3 with pressure cylinder.
In concrete enforcement, the insertion depth that compensation pipeline 9 inserts in compensating jacket 2 generally can be taken as 150-200m, should be reserved with the distance of 10-20mm between Gland 6 and casing flange 5 after high temperature flexible filler 3 compacting.
When pipeline long-play, the impact of the factors such as high temperature flexible filler 3 is worn, etch, aging, dry, temperature, when occurring that compactness reduces, high-temp and high-strength Compress Spring 7 advances Gland 6 automatically, compress high temperature flexible filler 3, remain its compactness, until preset space is zero between Gland and casing flange.Thus ensure the property safe and reliable to operation of pipeline compensator.
