Abstract
Disclosed by the invention is a kind of parallel Venturi tube cavitation apparatus, and this parallel Venturi tube cavitation apparatus is made up of bolt hole, ring flange, fluid intake, contraction section, fish mouth, venturi, diffuser, fluid issuing.Fish mouth by venturi be divided into above and below two parts, faster, good throttle effect, cavitation phenomenon is obvious for the flow velocity of venturi water up and down.Connected between Venturi tube and Venturi tube or using ring flange between Venturi tube and main line pipeline, pipeline good sealing effect, during flow oscillation, the probability of leakage is greatly lowered.In contraction section, diffuser caliber gradual change, flow process, because energy loss reduces caused by throttling in Venturi tube.The content that device can be studied is with strong applicability than wide.
Description
Technical field
The present invention relates to Hydrodynamic Cavitation Technology field, particularly a kind of parallel Venturi tube cavitation apparatus.
Background technology
When local pressure is reduced in Hydrodynamic Cavitation Technology field, liquid, gas space on liquid internal or the solid interface of liquid
The formation in cave (vacuole), the process for developing and crumbling and fall are referred to as " cavitation ".In cavitation processes, vacuole rapidly produces, expands and burst
Go out, shock wave or high-speed micro-jet can be formed in a liquid.At present, marine propeller, rudder, hydrofoil, underawater ordnance, water pump, water wheels
Machine, high speed culvert, gate slot, liquid rocket pump, cylinder jacket of diesel engine etc. can all run into Cavitation Problems, cause efficiency to reduce, material
Material degrades.So, cavitation is a popular topic at this stage.
At present, the experimental facilities of research cavitation mainly has cavitation water hole, decompression cabinet, vacuum towing basin, Venturi tube empty
Makeup is put, magnetostriction apparatus, rotating disk cavitation corrosion device, cavitation jet rifle, Single bubble cavitation generator etc., but using much still
Venturi tube cavitation apparatus.The principle of Venturi tube cavitation apparatus is：The flow section of water reduces, and flow velocity is accelerated, pressure reduction,
So as to produce cavitation.
At present, widely used Venturi tube cavitation apparatus structure is all substantially the same both at home and abroad, is existed " common fault ".Example
Such as：Throttling is simple, and restriction effect is bad, and cavitation phenomenon is not obvious；In experimentation, equipment performance is unstable, exist current from
The situation of Venturi tube two ends leakage；During water circulation, the energy loss of current is larger at Venturi tube, experimental provision
Do not save；Meanwhile, it is capable to which research is limited in scope, and the applicability of device is not strong etc..
Therefore, it is badly in need of a kind of obvious cavitation effect, equipment performance stabilization, the energy-saving Venturi tube with stronger applicability
Cavitation apparatus.
The content of the invention
The present invention is intended to provide a kind of parallel Venturi tube cavitation apparatus, is filled for solving Venturi tube cavitation at this stage
Put the series of problems such as existing cavitation effect is not obvious, equipment performance is unstable, energy loss is big, applicability is not strong.
The technical solution adopted for the present invention to solve the technical problems is：
This parallel Venturi tube cavitation apparatus by bolt hole, ring flange, fluid intake, contraction section, fish mouth, venturi,
Diffuser, fluid issuing composition.Wherein, method is used between Venturi tube and Venturi tube or between Venturi tube and main line pipeline
Blue disk connection；Fish mouth by venturi be divided into above and below two parts, venturi is in parallel up and down；Contraction section, diffuser caliber gradual change.
Advantages of the present invention：
Due to fish mouth by venturi be divided into above and below two parts, although the total flow size of water does not change, but upper lower larynx
Faster, restriction effect is more preferable for the flow velocity of water at road, it is easier to cavitation occurs here；It is between Venturi tube and Venturi tube or literary
Connected between venturi and main line pipeline using ring flange, pipeline sealing effectiveness is more preferable, during flow oscillation, the probability of leakage
It is greatly lowered；In contraction section, diffuser caliber gradual change, flow process, current streamline is more smooth, i.e., in Venturi tube because
Reduce for energy loss caused by throttling.Two or more Venturi tubes can also be connected by the way of ring flange connection, be filled
Put that the content that can be studied is more extensive, applicability is stronger.
Brief description of the drawings
Fig. 1 is the overall structure diagram of the present invention.
Fig. 2 is the left view of the present invention.
In figure：Bolt hole 1, ring flange 2, fluid intake 3, contraction section 4, fish mouth 5, venturi 6, diffuser 7, fluid issuing 8.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further illustrated：
This parallel Venturi tube cavitation apparatus by bolt hole 1, ring flange 2, fluid intake 3, contraction section 4, fish mouth 5,
Venturi 6, diffuser 7, fluid issuing 8 are constituted.Wherein, between Venturi tube and Venturi tube or Venturi tube and main line pipeline it
Between connected using ring flange 2；Fish mouth 5 by venturi 6 be divided into above and below two parts, venturi is in parallel up and down；Contraction section 4, diffuser 7 are managed
Footpath gradual change.
During work, water is entered by fluid intake 3, then flows sequentially through contraction section 4, venturi 6, diffuser 7, fluid issuing 8.
In contraction section 4 because caliber is gradually reduced, the flow velocity of water is gradually accelerated, so pressure can reduce always.On water is further separated into
After lower venturi 6, the degree of this section of caliber minimum, i.e. pressure reduction is maximum, and venturi 6 has sufficiently long length, and water, which just has, to be filled
With the sufficient time cavitation occurs at venturi 6 for the condition divided.After diffuser 4 is flowed to, caliber gradually increases, and water flow velocity subtracts
It is small, pressure increase, making the possibility of cavitation reduces, and this reduces destruction is degraded to main line pipeline, protects main line to manage
Line.
Due to fish mouth 5 by venturi 6 be divided into above and below two parts, although the total flow size of water does not change, but up and down
Faster, restriction effect is more preferable for the flow velocity of water at venturi 6, it is easier to cavitation occurs here；Between Venturi tube and Venturi tube
Or using ring flange connection between Venturi tube and main line pipeline, pipeline sealing effectiveness is more preferable, during flow oscillation, leakage
Probability is greatly lowered；In contraction section 4, the caliber gradual change of diffuser 7, flow process, current streamline is more smooth, i.e., in venturi
Because energy loss reduces caused by throttling in pipe.Two or more Venturi tubes also can be by the way of the connection of ring flange 2
Series connection, the content that device can be studied is more extensive, and applicability is stronger.
Such a parallel Venturi tube cavitation apparatus cavitation phenomenon is obvious, equipment performance is stable, good energy-conserving effect, with compared with
Strong applicability.
