Description
Technical field
The utility model relates to pipe-line equipment technical field, is specifically related to logical pressure balanced expansion joint.
Background technology
Expansion joint is also compensator traditionally, or telescopic joint.By forming the bellows (a kind of flexible member) of its operative body and holding the annexes such as pipe, support, flange, conduit to form.Expansion joint is the additional stress in order to compensate because temperature difference and mechanical oscillation cause, and is arranged on a kind of flexible structure on container casing or pipeline.Utilize effective dilatation of its operative body bellows, to absorb pipeline, conduit, container etc. by reason and the change in size produced such as expanding with heat and contract with cold, or axial, the transverse direction of compensation pipes, conduit, container etc. and angular displacement.Also can be used for noise-and-vibration-reduction.In heat supply, when heating up to prevent heat supply pipeline, causing pipe deforming or destruction due to thermal stretching or temperature stress, needing to arrange compensator on pipeline, to compensate the thermal stretching of pipeline, thus the stress reducing tube wall and the active force acted on valve member or supporting structure.
Due to expansion joint as a kind of can the elastic compensation element of free-extension, there is the advantages such as reliable operation, functional, compact conformation, be widely used in the departments such as chemical industry, metallurgy, nuclear energy.The expansion joint that container adopts, has various ways, with regard to the shape of ripple, applies the most extensive with U-shaped expansion joint, secondly also has Ω shape and C shape etc.And the expansion joint adopted on pipeline is with regard to structure compensation, be divided into again universal, pressure balance type, hinge type and Universal connector hair style etc.
But the limited pressure that existing expansion joint air bearing is subject to, can not absorb internal pressure thrust, rigidity is poor, guidance quality is general.
Summary of the invention
The purpose of this utility model is to provide logical pressure balanced expansion joint, and it has the ability absorbing internal pressure thrust, and self-balancing is superior compared with ZYP type; Rigidity is little, and guidance quality is good; Appearance and size is little, good economy performance.
In order to solve the problem existing for background technology, the utility model is by the following technical solutions: it comprises adapter, first bellows, reinforcing ring, second bellows, steam vent, interior end socket, outside head, pull bar, drain port, the outside of the second described bellows is socketed with interior end socket, the two ends, left and right of interior end socket are connected with outside head, the outside of described interior end socket is also provided with steam vent and drain port, the outside of the outside head at two ends, left and right is all connected with reinforcing ring, the outside port of reinforcing ring connects the first bellows, the outside port of the first bellows is connected with adapter, the arranged outside of described adapter has pull bar, pull bar is connected with outside head, the second described bellows and adapter, first bellows is communicated with.
The utility model has following beneficial effect: it has the ability absorbing internal pressure thrust, and self-balancing is superior compared with ZYP type; Rigidity is little, and guidance quality is good; Appearance and size is little, good economy performance.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention:
Referring to Fig. 1, this detailed description of the invention is by the following technical solutions: adapter 1, first bellows 2, reinforcing ring 3, second bellows 4, steam vent 5, interior end socket 6, outside head 7, pull bar 8, drain port 9, the outside of the second described bellows 4 is socketed with interior end socket 6, the two ends, left and right of interior end socket 6 are connected with outside head 7, the outside of described interior end socket 6 is also provided with steam vent 5 and drain port 9, the outside of the outside head 7 at two ends, left and right is all connected with reinforcing ring 3, the outside port of reinforcing ring 3 connects the first bellows 2, the outside port of the first bellows 2 is connected with adapter 1, the arranged outside of described adapter 1 has pull bar 8, pull bar 8 is connected with outside head 7, the second described bellows 4 and adapter 1, first bellows 2 is communicated with.
This detailed description of the invention has following beneficial effect: it has the ability absorbing internal pressure thrust, and self-balancing is superior compared with ZYP type; Rigidity is little, and guidance quality is good; Appearance and size is little, good economy performance.
