Description
Technical field
The present invention relates to a kind of flow uniform distributors.
Background technique
In engineer application, because pipeline is compared with fluid is larger by the resistance of pipeline, the method for the shunting taken thus.Together
When, using flow allocation method, to meet the purpose of each section, position and flow demand.In different in size, the Yi Jizhi of each branch
Road front-rear position relationship, so that the flow behavior in pipe is different, assignment of traffic also becomes uneven.In order to solve this problem,
It needs that flow uniform distributor is arranged, it is uniform to meet each rate of discharge.
Summary of the invention
The purpose of the present invention is to provide gas is made when distributing by branch, guarantee that assignment of traffic is uniform, to reach
To a kind of compressed air require uniform distributor with silencing function of optimum flow demand.
The object of the present invention is achieved like this:
A kind of compressed air require uniform distributor with silencing function of the present invention, it is characterized in that: including convex expander road, institute
Stating convex expander road is connected reduced diameter section and enlarged diameter section, and reduced diameter section connects main flow pipeline, and enlarged diameter section is cylinder knot
The downstream of the gas chamber of structure, cylindrical structure is closed, and is opened up airflow hole on the side wall of cylindrical structure, is cased with outside enlarged diameter section
Ventilative quieter material.
The present invention may also include:
1, the airflow hole is set by arrangement, and adjacent airflow hole between row and row is arranged in column or interlaced arrangement.
2, the taper of airflow hole is 15 ° -30 °.
3, the screw thread that the external setting of reduced diameter section is connect with main flow conduit, the ventilative quieter material are inorfil material
Material, the diameter of enlarged diameter section is 2 times of reduced diameter section diameter.
Present invention has an advantage that the present invention compared with existing invention, has structure simple, more uniform, noise reduction is distributed
The features such as.In existing invention, most of to use water conservancy diversion, sensor, the modes such as hydraulic regulation, which are realized, to be evenly distributed, but is existed and divided
With the disadvantages of uneven, structure is complicated, and reliability is not high, and processing installation is complicated.The present invention is by being threadedly engaged, convenient for loading and unloading,
It is structure-integrated simultaneously, improve reliability.Due to special construction feature of the invention, assignment of traffic can be preferably realized.
Detailed description of the invention
Fig. 1 is overall structure of the present invention (without external ventilative quieter material)；
Fig. 2 is global sections figure of the present invention；
Fig. 3 is A sectional view；
Fig. 4 is distribution of air flow schematic diagram；
Fig. 5 is the schematic diagram that adjacent airflow hole between row and row is arranged in column.
Specific embodiment
It illustrates with reference to the accompanying drawing and the present invention is described in more detail:
In conjunction with Fig. 1-5, a kind of compressed air require uniform distributor with silencing function of the present invention, including have airflow hole
1 Divergent Piping 3,4, reduced diameter section 3 connect main flow pipeline, and enlarged diameter section is gas chamber 4；Airflow hole 1 is located at air chamber
4 barrel surface of room arranges or is arranged in parallel in alternating expression；The closing of 4 downstream of gas chamber, does not arrange airflow hole；Airflow hole 1 has
Certain taper --- -15~30 °；Main flow pipe reduced diameter section 3 is connected, outside is connect using screw thread 2 with main flow conduit；Gas chamber 4
Outside is one layer of ventilative quieter material 5.
Primary structure of the present invention is the closed sudden expansion pipe 3,4 of big end, and sudden expansion size can be minor diameter according to major diameter
It twice, can be adjusted according to practical engineering application.Small end is the duct section 3 of minor diameter, is connected with the air distribution hole of main flow conduit, adopts
It is connected with 2 form of screw thread.In the pipeline top closure of major diameter, a cavity 4 is formed, there is airflow hole 1 on cavity cylindrical surface.
Airflow hole circumferentially interlaced arrangement, is uniformly distributed along axial direction, and has 15~30 ° of certain taper.Pore opening and quantity can roots
It is adjusted according to actual requirement of engineering.In the present invention, stomata totally 8 row, totally 144 stomatas.Stomata containment portion wraps up one layer of inorganic fibre
Material is tieed up, for homogenizing gas, reduces noise.Fibrous material has the characteristics of loose porous, good permeability.Fibrous material is thick
Degree is about twice of cavity thickness.
The present invention is a kind of compressed air require uniform distributor with silencing function, an including Divergent Piping is big straight
Diameter pipeline top closure, forms gas chamber, and reduced diameter section connects mainstream gas pipeline.Outside diameter is twice of minor diameter.
Airflow hole is opened up around gas chamber, in being uniformly staggered.Airflow hole cone angle is 21.8 degree, and pore opening and quantity can bases
Actual requirement of engineering adjustment.It is external thread structure outside reduced diameter section, is connect with branch road air distribution hole.Such as Fig. 4, gas passes through master
Flow tube road, the air distribution hole 7 of branch road 6 enter gas chamber by reduced diameter section sudden expansion, and subsequent gas passes through metering orifice to outflow
Out, external inorganic fibers are flowed through, since density is larger, the full and uniform mixing of gas is gone out by clearance flow therebetween.Due to gas
Body outflow aperture can generate noise, and exterior material has noise reduction effect simultaneously.Inorganic fibers, intensity is high, corrosion-resistant, is not easy
The advantages that burning, can be applied to a variety of use environments.
Fig. 1 airflow hole is to be staggered, and air-flow pore size distribution can be uniform parallel arrangement such as Fig. 5, and the present invention is preferably gas
Discharge orifice is staggered.
Preferably as the present invention, airflow hole cone angle is 21.8 degree, and airflow hole converts into diameter 4mm relative wall thickness 2.5mm, air-flow
Cone angle can be depending on use condition.
