Into water pocket cavity；Described water pocket cavity both sides are symmetrically arranged with water pocket water inlet adapter mouth, and bottom symmetrical is provided with water pocket blowdown
Adapter mouth.
Described water pocket body is tetragonal structure；Described tetragonal structure bottom is provided with square space.
Described water pocket body and support between connecting plate by supporting the connection of connecting plate riveting screw thread.
It is threadedly coupled by pressing plate fixed screw between described the first noumenon and the second body and water pocket edge-pressing board.
Support bar connecting bolt is provided with described support connecting plate.
A kind of expansion compensation seam shielding water pocket of this utility model, provides effectively for the expansion compensation seam at fuel transport passage
Compensation and radiation shield, compared with traditional structure：The medium of certain pressure is passed through by water pocket water inlet adapter mouth so that water pocket
Water pocket expandable cavity on body, in the expansion compensation seam at fuel transport passage closed barrier is formed, and is changed existing swollen
The deficiency of swollen compensation seam Shielding plan, and it is superior with easy construction, economy height, anti-seismic performance, the advantages of safe and reliable.

Specific embodiment
In order that goal of the invention of the present utility model, technical scheme and its Advantageous Effects become apparent from, below in conjunction with
The drawings and specific embodiments, are further elaborated to this utility model；
In the accompanying drawings：A kind of expansion compensation seam shielding water pocket, including water pocket body 1；It is provided with described water pocket body 1
Support connecting plate 2 and water pocket protective bag 3；Support bar connecting bolt 13 is provided with described support connecting plate 2；Described water pocket
Body 1 be threadedly coupled by supporting connecting plate riveting screw 11 between connecting plate 2 with being supported, and not only ensure that water pocket body 1
Structural strength, and be located by connecting by support bar connecting bolt 13 and miscellaneous part when being easy to actually used installation；Described
Water pocket protective bag 3 not only plays a part of to protect water pocket body 1, and the sealing of itself is played further to water pocket body 1
Booster action, safety is higher；Described water pocket body 1 includes two block structure identical the first noumenons 4 and the second body 5；
The described periphery of 4 and second body of the first noumenon 5 is compressed by water pocket edge-pressing board 6, forms water pocket cavity 7；Described first
It is threadedly coupled by pressing plate fixed screw 12 between the body 5 of body 4 and second and water pocket edge-pressing board 6, it is ensured that the knot of water pocket body 1
Structure intensity；Described water pocket cavity 7 not only serves the effect of storage liquid, and can pass through to adjust the pressure of storage liquid
So that water pocket cavity 7 expands, shielding and the effect for compensating are reached；The described left and right sides of water pocket cavity 7 is both provided with water pocket and enters
Water adapter mouth 8, bottom symmetrical is provided with water pocket blowdown connection mouth 9；Described water pocket water inlet adapter mouth 8 is easy to water pocket cavity 7
The medium of certain pressure is passed through so that water pocket body 1 expands, the effect of the expansion compensation seam at compensation fuel transport passage is reached；
Described water pocket blowdown connection mouth 9 is easy to be used during cleaning.
Described water pocket body 1 is tetragonal structure；Described tetragonal structure bottom is provided with square space 10；It is described
Square space 10 facilitate conduit component to penetrate.
This utility model is compared with conventional art：
1. when actually used, the mobility scale of expansion compensation seam is 29.7 ~ 56.0mm, and expansion compensation seam shielding water pocket should
Energy radial expansion clogs all the time expansion compensation seam, is led to water pocket body 1 installed in fuel transport by support bar connecting bolt 13
At expansion compensation seam at road, then certain pressure is passed through into water pocket cavity 7 by water pocket water inlet adapter mouth 8 from liquid storage water tank
Deionized water causes water pocket body 1 to expand, and reaches the effect of the expansion compensation seam at compensation fuel transport passage, same water pocket sheet
