Have between valve element and plug in head, cylinder on compressed air, joint and be connected with triple valve, one of water outlet of triple valve
End is connected with joint.This water hammer absorber, which has, is easy to use and installs conveniently advantage.
This water hammer absorber may be only available for the connection of the pipeline of metal material, can not be nonmetallic suitable for being connected in
On pipeline.
The content of the invention
The utility model technical issues that need to address：A kind of direct hair style water hammer absorber is provided, this water hammer absorbs
Device is easy to be connected and fixed in the infusion pipeline of non-metallic material.
To solve the technical problem, the technical solution of the utility model：A kind of direct hair style water hammer absorber, including cylinder
Body and coupling head, cylinder one end open, other end closing, hollow coupling head are connected in the openend of cylinder, set in cylinder
There is piston, the outer end connection of coupling head has hollow straight joint, it is characterised in that in being made in straight joint provided with elastomeric material
Empty liner, is formed with the assembly cavity of annular, assembly cavity between liner and straight joint are inner and is provided with hollow choker block, choker block
It is made up of elastomeric material, choker block is in frustoconical, the small head end of choker block is located in coupling head；The outer end of coupling head carries outer spiral shell
Internal thread is provided with line, the inner of straight joint, coupling head and straight joint are threaded togather.
In the outer end of straight joint integrally formed with interior to bulge loop, the outer end of liner is resisted against on the interior inner surface to bulge loop.
One end side portion is radially protruded in straight joint.
The wall thickness of straight joint concave portion is more than the wall thickness of the outer one end side portion of straight joint.
Choker block stub end is resisted against on the step surface formed in straight joint.
Interior oral area in coupling head outer end is formed with fillet surface.
Therefore, the beneficial effects of the utility model：This water hammer absorber is used for and non-metallic pipe such as aluminium-plastic pipe is connected and fixed,
Non-metallic pipe is plugged into liner, in straight joint and coupling head rundown process is realized, due to the shape of choker block, and coupling head can make
To contraction in choker block generation, and then liner is promoted to wrap on nonmetallic surface, and when liner is radially deformed more
Gently, the local deformation of non-metallic pipe wall body is not resulted in, so as to conveniently realize the firm of non-metallic pipe and water hammer absorber
Connect.Being connected and fixed between this water hammer absorber and non-metallic pipe is easy to operate, and the connection fastness between them can be obtained
Meet, the job requirement of water hammer absorber is ensure that well.
Brief description of the drawings
Fig. 1 is the longitudinal sectional view of this direct hair style water hammer absorber.
Fig. 2 is the longitudinal sectional view of coupling head.
Embodiment
With reference to accompanying drawing, this directly hair style water hammer absorber, including cylinder 1 and coupling head 8, the one end open of cylinder 1, the other end
Closing.The openend of cylinder 1 is plugged in hollow coupling head 8, and both is connected and fixed together by way of welding.
Piston 3 is provided with cylinder 1, the outer peripheral face of piston 3 is provided with twice O-ring seals 2, and realizes between piston 3 and cylinder 1
Hermetic seal.Piston 3 is located at the position of coupling head 8 in cylinder 1, integrally formed with interior to shoulder 10 in coupling head 8, for handle
Piston 3 is limited in coupling head 8, and air is sealed between the blind end of piston 3 and cylinder 1.
The outer end connection of coupling head 8 has in hollow straight joint 4, straight joint 4 provided with the liner being made up of rubber or silica gel
6, liner 6 is hollow.The assembly cavity of annular is formed between liner 6 and the inner of straight joint 4, the assembly cavity can be described as follows
Formed by the extending out for appropriate section of straight joint 4, or the external diameter of the appropriate section of liner 6 is inside contracted and formed.
Hollow choker block 7 is provided with assembly cavity, the material of choker block 7 is consistent with the material of liner 6.The shape of choker block 7 is in cut
