Abstract
The utility model discloses a straight-through side balance non-thrust corrugated pipe compensating device. The utility model uses a left connecting pipe, a compensating corrugated pipe, a flow guiding pipe and a right connecting pipe which are respectively connected in seal on the same axial line to form a medium straight-through compensating passage. In addition, a balance system composed of a fixed support bracket, a side left connecting pipe, a balance corrugated pipe, a side right connecting pipe, a sliding support bracket, a communicating pipe and a drainage screw hole is arranged on one side of the medium straight-through compensating passage. The other three sides are not provided with components. The utility model has the advantages of simple structure, straight-through medium without flowing resistance and small radial size. The utility model can conveniently select an installing position to avoid a contiguous pipeline and realize the arrangement of small space distances of pipe galleries and pipe networks.
Description
Technical field
The utility model relates to a kind of thrustless compensator, belongs to tube equipment.
Background technique
In the piping lane of the harbour of oil, chemical industry, smelter and relevant industries, harbour, tunnelling works, pipe network, widely apply thrustless compensator.Although can compensating because of medium temperature, prior art changes the axial displacement that the pipeline cause expands with heat and contract with cold and produces, also can interior pressure of equalizing main change the end thrust that causes, but, prior art radial structure size is big, in the application, occupy than the large space position, increase the adjacent channel spacing, cause thus that the support of pipelines size is big, quantity is many, engineering cost is big, prior art can not satisfy in the engineering the little requirement of corrugated expansion joint radial structure size.
The model utility content
The purpose of this utility model provides a kind of straight-through lateral balance does not have thrust corrugated expansion joint technological scheme, this compensator only is provided with balance sysmte in straight-through compensation channel two sides of medium, other three side does not have member, thereby overcomes the complicated and big deficiency of radial dimension of above-mentioned prior art radial structure.
The utility model is achieved by following technical proposals.
A kind of straight-through lateral balance does not have the thrust corrugated expansion joint, form with bellows, the right adapter of side, cross over pipe, drainage screw, push-pull screw and nut with bellows, honeycomb duct, right adapter, fixed support, sliding support, the adapter of a side left side, balance by left side adapter, fixed plate, compensation, a left side is taken over, compensation is with bellows, honeycomb duct, the right sealed attachment successively of taking on same axis, forms the straight-through compensation channel of medium; Fixed support, the adapter of a side left side, balance is characterized in that with bellows, the right adapter of side, sliding support, cross over pipe, drainage screw Compositional balance system described balance sysmte is in the straight-through compensation channel one side setting of medium.
Balance sysmte in the said structure is in the straight-through compensation channel one side setting of medium, and when compensation with bellows functional axial deformation takes place with bellows, balance, sliding support will be taken on the outer wall on the right side and move axially accordingly.In straight-through compensation channel of medium and balance sysmte, 1～4 identical bellows of parameter is set with waiting quantity respectively, because the channeling of cross over pipe, compensation equates with the axial deflection that bellows takes place under same operating mode with bellows and balance, but the axial deformation direction is opposite, can compensate each other effectively with balance line system in axial deformation and end thrust, make pipe-line system be in a kind of no thrust conditions.Drain screw and only be the passage of using as exhaust or blowdown.
Owing to adopt above technological scheme, the utility model is more simple in structure than the pressure-equalizing corrugated pipe compensator of existing same specification straight tube bypass type, the straight-through pressure-balancing type corrugated expansion joint of straight tube, medium channel does not have flow resistance, and the radial structure size is little, volume is little, in light weight.The most important thing is that the utility model only has member in straight-through compensation channel one side, other three side does not have member, during installation easily chosen position dodge adjacent channel, can realize that the little spacing of piping lane, pipe network arranges.
Description of drawings
Accompanying drawing is the utility model structural representation.
Embodiment
In the present embodiment, left and right sides bellows is made by alloyed steel, and the material of all the other members is carbon steel or alloyed steel.Take over the same successively axis sealed attachment compensation of 1 outer wall right-hand member on a left side with bellows 2, right adapter 9, take over 1 inwall connection honeycomb duct 11 on a left side and form straight-through compensation channel.Same successively axis sealed attachment side left side adapter 4 on fixed support 3 right planes, balance bellows 6, the right adapter 7 of side, sliding support 8, sealed attachment cross over pipe 12 and drainage screw 5, formation balance sysmte.Balance sysmte assembly, fixed plate 10 are set in the assigned position on the straight-through compensation channel and are fixedly connected, push-pull screw 13 is installed at last and fastening nut 14 is formed a complete straight-through no thrust sides balance corrugated expansion joint.The utility model compensate reliably with balance sysmte in axial deformation and end thrust.
Claims (4)
