In the above-mentioned bellows component with slip-preventing structure, described first take over cushion block weld, it is described
Diversion pipe is welded with cushion block.
In the above-mentioned bellows component with slip-preventing structure, the cushion block at least two, adjacent pod it
Between form communication port.
In the above-mentioned bellows component with slip-preventing structure, circumferential uniform point around diversion pipe of the cushion block
Cloth.
In the above-mentioned bellows component with slip-preventing structure, the cushion block has radian.
In the above-mentioned bellows component with slip-preventing structure, the slip-preventing structure further includes washer, described
Washer fixation be set on diversion pipe.
In the above-mentioned bellows component with slip-preventing structure, the washer and second take between formed circulation
Gap.
In the above-mentioned bellows component with slip-preventing structure, the diversion pipe has a first end and a second end,
The first end is taken over corresponding with first, and second end is taken over corresponding with second, and cushion block is located at first end, and washer is located at the
Two ends.
Compared with prior art, this bellows component with slip-preventing structure is：Diversion pipe and first
It takes over and is fixedly connected, medium is flowed out through the gap, and no matter medium passes through from which end, and flow, flow velocity, pressure are impossible to
Diversion pipe is allowed to dislocate；Communication port is sized to be controlled according to demand, more stably and controllable；It only needs to weld several cushion blocks
, structure is relatively simple, is also convenient for processing, processing cost is low.
Description of the drawings
Fig. 1 is transverse sectional view provided by the utility model.
Fig. 2 is longitudinal sectional view provided by the utility model.
In figure, diversion pipe 1, bellows 2, the first take over 3, the second take over 4, cushion block 5, washer 6, passage gaps 7, first end
8th, second end 9, communication port 10.
Specific embodiment
Following embodiment only exists in illustrative purpose, without being intended to limitation the scope of the utility model.
Embodiment
As shown in Figs. 1-2, there is the bellows component of slip-preventing structure to include diversion pipe 1, bellows 2, the first take over 3 for this
With the second take over 4, bellows 2 is set on diversion pipe 1, and one of the first take over 3 and bellows 2 is connected, the second take over 4 with
The other end of bellows 2 is connected, which is characterized in that slip-preventing structure is equipped between 1 and first take over 3 of diversion pipe, it is anti-slip
Structure is cushion block 5, and the first take over 3 is fixedly connected with cushion block 5, and diversion pipe 1 is fixedly connected with cushion block 5.
When main pipeline heat expansion, bellows 2 shortens, and diversion pipe 1 is moved to 4 direction of the second take over, so as to heat expansion effect
It is offset, when main pipeline shrinkage, bellows 2 extends, and diversion pipe 1 is moved to 3 direction of the first take over, so as to shrinkage effect
It is offset.Diversion pipe 1 is fixedly connected with the first take over 3, except 5 part of cushion block, between the first take over 3 and diversion pipe 1
Gap is formed, medium is flowed out through the gap, and no matter medium passes through from which end, flow, flow velocity, pressure, is impossible to allow diversion pipe 1
Dislocation.
