Description
Technical field
The utility model relates to the middle temperature mesolow pipeline restraint device of a kind of petrochemical industry and energy industry, especially a kind of device of limit levels piping displacement.
Background technique
Pressure piping is used extremely wide at present, at a large amount of pipelines of industrial field existence in various degree such as oil, chemical industry and power industries, each links such as their design, manufacturing, installation and operation are all established one's own system, and have formulated the standard of some row, have guaranteed the safety of pipeline.
In piping design and operation phase, often for the stable and controlling plumbing fixtures vibration of pipeline, on some directions (some even any) direction, give rigid constraint, with displacement that limits this direction and the load of bearing this direction, Here it is rigid constraint device.
The rigid constraint device is owing to the effect of undertaking restriction conduit displacement and bearing load and stablizing piping in pipeline, so each link such as their design, installation and operation are all extremely important.The kind of rigid constraint is a lot of at present, (medium temperature is less than 300 degree at the medium temperature and medium pressure pipeline, pressure medium is less than 10MPa) on, basically be to adopt channel-section steel or I-steel and pipeline itself to weld together, though can play the effect of restriction conduit displacement like this, the welding job amount is big, the construction trouble reaches in the future and may see Fig. 1 because stress causes shortcomings such as pipeline cracking greatly but exist in the construction at the scene.
Summary of the invention
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, a kind of rigidity that can improve pipeline is provided, increases the stability of pipeline, significantly reduce the welding job amount of pipeline, tubulation road abnormal displacements, the device of the limit levels piping displacement of the safe operation of assurance equipment.
For achieving the above object, the utility model adopts following technical proposals:
A kind of device of limit levels piping displacement, comprise spacing framework, block and diagonal brace, on the periphery of pipeline, be provided with spacing framework, spacing framework links to each other with embedded part on the face of taking root by diagonal brace, be provided with block with the pipeline cylindrical of spacing framework touching position, described block is distributed in the both sides of spacing framework, and block contacts with spacing framework is seamless.
Described spacing framework is the rectangular frame that is welded by four channel-section steels, and wherein the face of taking root is inserted in the extension of two channel-section steels up and down.
Described block is welded on the pipeline cylindrical, has eight, and spacing framework both sides respectively have four blocks to be evenly distributed on the pipe circumference and are close to four limits of spacing framework.
The purpose of this utility model is the displacement of control medium temperature and medium pressure pipeline, by the combination of spacing framework and postioning abutment, has limited the displacement of pipeline.Working principle is as follows: the utility model is by the displacement of three directions of restriction conduit and the rotation of three directions, and making herein displacement and rotational angle is zero, becomes immovable point herein.The utility model has changed the setting of traditional immovable point, has significantly reduced on pipeline the directly workload of welding, has prolonged pipeline working life, has guaranteed equipment safety operation, is applicable to the displacement control of medium temperature and medium pressure pipeline.
The utlity model has advantages such as rational in infrastructure, esy to use, safe and reliable, that effect is remarkable.

Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Among Fig. 2-4, on the periphery of pipeline 1, be provided with spacing framework 2, spacing framework 2 links to each other with embedded part on the face of taking root 4 by diagonal brace 3, be provided with block 5 with pipeline 1 cylindrical of spacing framework 2 touching positions, described block 5 is distributed in the both sides of spacing framework 2, and block 5 and spacing framework 2 seamless contacts.
Described spacing framework 2 is the rectangular frames that are welded by four channel-section steels.Article four, channel-section steel is welded into the spacing framework of rectangle and is close to the pipeline outside, and restriction conduit is the displacement of (four direction up and down among Fig. 3) radially, and wherein the face of taking root is inserted in the extension of two channel-section steels up and down.
Described block 5 is welded on pipeline 1 cylindrical, has eight, and spacing framework 2 both sides respectively have four blocks 5 to be evenly distributed on pipeline 1 circumference and are close to four limits of spacing framework 2.Positive stop 5 has eight, be divided into two groups, each is organized four and is welded on pipeline 1 outside respectively, along the even distribution (see figure 3) of circle spacing 90 degree, two groups of blocks 5 are positioned at the both sides (seeing Fig. 2 and Fig. 4) of spacing framework, and contact with channel-section steel is seamless, like this can restriction conduit displacement vertically, i.e. pipeline 1 left and right directions displacement among Fig. 2 and Fig. 4.
One end of two diagonal braces 3 and the front end of spacing framework are welded together, and the other end is fixed on the embedded part of the face of taking root 4, plays the effect that strengthens and fixes spacing framework.
Embodiment 1: as shown in Figure 5, unit capacity is 289 ℃ of the cooling water piping design running temperatures of 300MW unit, and design pressure 7.32MPa, #1 height add that hydrophobic critical drain water piping is in service to exist judder, have a strong impact on the security of operation of pipeline.
This pipe vibration reason is that pipeline is longer, and elbow is many, lacks necessary limit stoper, causes that hydrophobic band vapour causes the resonance of pipeline.According to designing requirement, need set up two place's limit stoper, see the following form 1.Node location sees that Fig. 5 illustrates.It is all qualified to set up behind the limit stoper stress of each cell node, each limit stoper to the reaction force of pipeline in reasonable level.
