Abstract
The invention discloses a single straight-pipe bypass external pressure type pressure balancing expansion joint. The technical scheme is that the pressure balancing expansion joint comprises a first corrugated pipe with pulling-rod combinations, and a second corrugated pipe of a seal structure, wherein one end of the first corrugated pipe is connected with a left connecting pipe, the other end of the first corrugated pipe is connected with the second corrugated pipe, the other end of the second corrugated pipe is fixedly connected with a right connecting pipe, the left and right ends of the second corrugated pipe are provided with a left blind plate and a right blind plate, an outer protecting bush is fixedly connected with a limiting ring and is slidingly connected with the left connecting pipe by the limiting ring, the sealing part of the outer protecting bush is provided with a seal ring, the outer surface of the left connecting pipe is symmetrically provided with the two pulling-rod combinations to connect the left connecting pipe with the outer protecting bush, and a hose passes through the right connecting pipe and the right blind plate to be connected with a dewatering opening in the outer protecting bush. The pressure balancing expansion joint has the following beneficial effects that not only can lateral displacement stress caused by pipeline thermal-deformation be absorbed, but also axial displacement stress caused by inner pressure can be absorbed; the pressure balancing expansion joint also has the characteristics of small rigidity and small outline size.
Description
Technical field
The present invention relates to expansion joint application, relate in particular to single entry straight tube bypass external pressure balance expansion joint.
Background technique
In various work, living facilities, the use of pipe-line system is of common occurrence, the thermal distortion causing due to high temperature, high pressure in order to compensate pipeline, we often use some expansion joints to solve, although but general straight-through type expansion joint energy heat-absorbing deformation, but can not compensating axial thrust, and bulky.
Summary of the invention
In order to address the above problem, the object of this invention is to provide a kind of single entry straight tube bypass external pressure balance expansion joint, this expansion joint has two bellowss, both the thermal distortion can extraction duct Yin Gaowen causing, the end thrust producing in again can bucking-out system, and the present invention has the advantages that rigidity is little, boundary dimension is little.
To achieve these goals, technological scheme of the present invention is achieved in that single entry straight tube bypass external pressure balance expansion joint, it comprises the first bellows 2 with pull bar combination and the second bellows 3 of sealing configuration, described first bellows 2 one end are connected with left adapter 1, the other end is connected with described the second bellows 3, the right-hand member of described left adapter 1 has left pore 10, the other end of described the second bellows 3 is fixedly connected with right adapter 4, the two ends, left and right of described the second bellows 3 are provided with left blind plate 16, right blind plate 15, the left end of described right adapter 4 has right pore 14, oversheath 5 is fixedly connected with limited ring 9, described oversheath 5 is slidably connected by limited ring 9 and described left adapter 1, and described oversheath 5 sealing parts are provided with seal ring 11, on described left adapter 2 outer surfaces, be symmetrical arranged two risers 6, pull bar 8 couples together described left adapter 2 and described oversheath 5 by described riser 6, nut 7 is fixed on described pull bar 8 on described riser 6, flexible pipe 13 is through described right blind plate 15, right adapter 4 is connected with the drain port 12 on described oversheath 5.
Further, described the first bellows 2, the second bellows 3 are the identical ripple original paper of geometric parameter and the flexible element of taking over formation.
Further, the area sum of described pore 10 equals cross-section of pipeline area.
Further, described flexible pipe 13 external layers are wire, and nexine is that high temperature resistant, corrosion-resistant material is made.
The present invention has following beneficial effect: the bellows with pull bar in the present invention absorbs lateral displacement stress, and the bellows absorption axes of by-pass structure is to displacement stress, the end thrust being caused by interior pressure like this will can not be passed to the related facilities such as equipment in pipeline system, container, pipe support.The present invention also has the feature that rigidity is little, boundary dimension is little.
