And first be provided with slip-preventing structure between adapter, described slip-preventing structure is cushion block, and first takes over and be fixedly connected with cushion block, leads
Flow tube is fixedly connected with cushion block.
In the above-mentioned bellows component with slip-preventing structure, the described first adapter is welded with cushion block, described
Mozzle welds with cushion block.
In the above-mentioned bellows component with slip-preventing structure, described 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 mozzle of described cushion block
Cloth.
In the above-mentioned bellows component with slip-preventing structure, described cushion block has radian.
In the above-mentioned bellows component with slip-preventing structure, described slip-preventing structure also includes packing ring, described
Packing ring fix be set on mozzle.
In the above-mentioned bellows component with slip-preventing structure, circulation is formed between described packing ring and the second adapter
Gap.
In the above-mentioned bellows component with slip-preventing structure, described mozzle has first end and the second end,
Described first end is corresponding with the first adapter, and the second end is corresponding with the second adapter, and cushion block is located at first end, and packing ring is positioned at the
Two ends.
Compared with prior art, there is the advantages of bellows component of slip-preventing structure to be for this：Mozzle and first
Adapter is fixedly connected, and medium flows out through the gap, and no matter medium passes through from which end, flow, flow velocity, pressure, is impossible to
Mozzle is allowed to dislocate；Communication port is sized to be controlled according to demand, more stably and controllable；Only need to weld some cushion blocks
, structure is relatively simple, is also convenient for processing, processing cost is low.
Brief description of the drawings
Fig. 1 is transverse sectional view provided by the invention.
Fig. 2 is longitudinal sectional view provided by the invention.
In figure, mozzle 1, bellows 2, the first adapter 3, the second adapter 4, cushion block 5, packing ring 6, passage gaps 7, first end
8th, the second end 9, communication port 10.
Embodiment
Following examples only exist in illustrative purpose, without being intended to limit the scope of the present invention.
Embodiment
As shown in Figure 1-2, there is the bellows component of slip-preventing structure to include mozzle 1, bellows 2, the first adapter 3 for this
With the second adapter 4, bellows 2 is set on mozzle 1, and one of the first adapter 3 and bellows 2 is connected, the second adapter 4 with
The other end of bellows 2 is connected, it is characterised in that slip-preventing structure is provided between the adapter 3 of mozzle 1 and first, it is anti-slip
Structure is cushion block 5, and the first adapter 3 is fixedly connected with cushion block 5, and mozzle 1 is fixedly connected with cushion block 5.
When main pipeline heat expansion, bellows 2 shortens, and mozzle 1 moves to the direction of the second adapter 4, so as to heat expansion effect
Offset, when main pipeline shrinkage, bellows 2 extends, and mozzle 1 moves to the direction of the first adapter 3, so as to shrinkage effect
Offset.Mozzle 1 is fixedly connected with the first adapter 3, except the part of cushion block 5, between the first adapter 3 and mozzle 1
Gap is formed, medium flows out through the gap, and no matter medium passes through from which end, flow, flow velocity, pressure, is impossible to allow mozzle 1
