【Embodiment】
The following example is further explanation of the present invention, and the present invention is not limited in any way.
Refering to Fig. 1, air energy pipeline fluid wave filter 100 of the invention includes filter main body 10, elastic thin-wall flexible pipe
20 and ozzle 30.The wave filter is installed in practical application on the pipeline between fluid pump and load, and fluid pump is exported
Flow and pressure filtering after be output to load, described load can be the equipment such as ultrafiltration, chromatography.
As shown in figure 3, the filter main body 10 is tubular body made of stainless steel, its both ends is provided with pipe joint 11, uses
It is connected in fluid-transporting tubing.Inwall in the filter main body 10 between the pipe joint 11 at both ends in arcuation to
Outer expansion so that the inner chamber of filter main body 10 is in elliposoidal.Between the inwall of the pipe joint 11 and the elliposoidal inwall
By the transition of ring bodies 12, the ring bodies 12 is inwardly protruding, forms undergauge, is easy to seal off elastic thin-wall flexible pipe 20 and wave filter
Air between main body 10.
As shown in figure 1, being provided with elastic thin-wall flexible pipe 20 in filter main body 10, the elastic thin-wall flexible pipe 20 can be silicon
Sebific duct or emulsion tube or rubber tube, its can air pressure effect under elastic deformation.In the present embodiment, the elasticity
Thin walled hose 20 is to meet the high intensity silicone tube of hygienic requirements.The elastic thin-wall flexible pipe 20 is prolonged by one end in filter main body 10
The other end is extended, and the both ends of elastic thin-wall flexible pipe 20 are fixed by ozzle 30 and the sealing of filter main body 10.
For the structure of ozzle 30 as shown in figure 4, the ozzle 30 is tubular body made of stainless steel, its internal diameter is less than the bullet
The internal diameter of property thin walled hose 20, two ozzles 30 are embedded in both ends in the filter main body 10 by stationary fit, each ozzle 30
One end is provided with cyclic convex edge 31, and the end face of the convex edge 31 is concordant with the end face of the pipe joint 11 of the filter main body.In ozzle
30 outer wall is provided with the annular projection 32 of evagination, and in the present embodiment, the annular projection 32 is curved, the annular projection of ozzle 30
32 are pressed on elastic thin-wall flexible pipe 20 on convex ring bodies 12, so as to which the aeroseal in the cavity 40 be isolated.
As shown in figure 1, formed with the cavity 40 for accommodating air, chamber between filter main body 10 and elastic thin-wall flexible pipe 20
, can be to flowing through elastic thin-wall flexible pipe by the change of the volume of the air in cavity 40 filled with the air that pressure is normal pressure in body 40
The flow and pressure of fluid in 20 carry out dynamic regulation, flow and pressure is in plateau.Due to elastic thin-wall flexible pipe
20 are pressed on by ozzle 30 at the annular projection 32 on the outer wall of ozzle 30 so that flow through the fluid in elastic thin-wall flexible pipe 20 and institute
The air stated in cavity 40 is completely isolated.When the flow and pressure for flowing through the fluid in elastic thin-wall flexible pipe 20 produce fluctuation,
So that elastic thin-wall flexible pipe 20 is deformed, this deformation causes the volume of air in cavity 40 to change, and volume of air
Change then the flow of fluid and the fluctuation range of pressure are attenuated, and the flow of fluid pump output and pressure are in
Poised state.
As shown in figure 5, the wave filter 100 is installed in practical application on the pipeline between fluid pump 50 and load 60,
Load 60 is output to after flow and the pressure filtering that fluid pump 50 is exported, described load can be that ultrafiltration, chromatography etc. are set
It is standby.
Although being disclosed by above example to the present invention, protection scope of the present invention is not limited thereto,
Under conditions of without departing from present inventive concept, each component is done to more than deformation, replacements etc. will fall into right of the invention
In claimed range.
