Description
Technical field
The present invention relates to Hydrodynamic Cavitation Technology field, particularly a kind of tandem Venturi tube cavitation apparatus.
Background technology
In Hydrodynamic Cavitation Technology field, often due to pressure reduce the process for vaporizing water (or other liquid) call it is " empty
Change ", the gas core that cavitation is formed in water is referred to as " vacuole ".Vacuole in water produces very big instant pressure when crumbling and fall, when routed
When going out generation near the surface of solids, the repeated action of the High Voltage produced by the vacuole constantly crumbled and fall in current can destroy solid
Body surface face, this phenomenon is referred to as " cavitation corrosion ".For a long time, although the theory of cavitation has had a great development, but with relating to
And the field of cavitation phenomenon is gradually increased, cavitation phenomenon is also considered as a masty problem.
At present, the drawbacks of there is different types of Venturi tube cavitation apparatus both at home and abroad, but have certain.For example：Literary mound
In pipe throttled only with one-level, cavitation phenomenon is obvious；The work that can be simulated in the determination of venturi throat size, experimentation
Condition is limited, and applicability is poor；Device structure is complicated, and equipment performance is unstable etc. in experimentation.
Therefore, a kind of simple in construction, cavitation phenomenon of urgent need is obvious, equipment performance is stable, the literary mound with stronger applicability
In pipe cavitation apparatus.
The content of the invention
The present invention is intended to provide a kind of tandem Venturi tube cavitation apparatus, for solving current Venturi tube cavitation apparatus
Existing complicated, cavitation phenomenon not substantially, the series of problems such as equipment performance is unstable, applicability is poor.
The technical solution adopted for the present invention to solve the technical problems is：
This tandem Venturi tube cavitation apparatus by external screw thread, inlet, contraction section, venturi, expansion segment, internal thread,
Liquid outlet is constituted.It is made up of inside Venturi tube contraction section, venturi, expansion segment；Multiple Venturi tubes can be connected through a screw thread and
Tandem；Tandem Venturi tube cavitation apparatus throat diameter is provided with plurality of specifications, can be different straight by selecting specification to be formed
Footpath tandem compound.
Advantages of the present invention：
Because multiple Venturi tubes can connect, multi-level throttle is formed, the degree of pressure reduction is added, the effect of cavitation is more
Plus substantially；Venturi tube is influenceed smaller, the performance of equipment is more in experimentation by the way of threaded connection by the disturbance of water
It is stable；It is made up of inside Venturi tube contraction section, venturi, expansion segment, current streamline is smooth, reduces the energy loss of current；
The throat diameter of this kind of Venturi tube can have different specifications, and the Venturi tube series connection of different size can simulate different operating modes,
Drastically increase the scope of application of this kind of device.
Brief description of the drawings
Fig. 1 is the structural representation of Venturi tube.
Fig. 2 is two kinds of specification Venturi tube series connection schematic diagrames.
Fig. 3 is Venturi tube left view.
Fig. 4 is Venturi tube right view.
In figure：External screw thread 1, inlet 2, contraction section 3, venturi 4, expansion segment 5, internal thread 6, liquid outlet 7.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further illustrated：
As shown in figure 1, this tandem Venturi tube cavitation apparatus by external screw thread 1, inlet 2, contraction section 3, venturi 4,
Expansion segment 5, internal thread 6, liquid outlet 7 are constituted.As shown in Fig. 2 when two Venturi tube series connection, the Venturi tube of one-level throttling
The external screw thread 1 of Venturi tube of internal thread 6 and two-step throttle coincide.As shown in figure 3, circle or circle in Venturi tube left view
Arc, is followed successively by outward from interior：Venturi contour line, external screw thread root circle, external screw thread outside circle, Venturi tube outer contour.Such as Fig. 4
Shown, circle or circular arc in Venturi tube right view are followed successively by outward from interior：Venturi contour line, internal thread root circle, internal thread
Outside circle, Venturi tube outer contour.
During work, water is entered by inlet 2 first, then flows sequentially through contraction section 3, venturi 4, expansion segment 5, liquid outlet 7.
In contraction section 3 because the flow section of water reduces, water flow velocity is increased sharply, pressure reduction, and vacuole is produced in water, and in venturi
Cavitation occurs at 4.
When cavitation phenomenon is not obvious at venturi 4, i.e., the suction strength that is formed in venturi 4 not enough, can now connect two
Individual Venturi tube, forms two-stage throttling.In the case of two-stage throttling, although first order throttling can aggravate water without cavitation phenomenon
The disturbance of stream, forms enough vacuoles, and vacuole throttles with the current direction second level, is produced at second venturi throat 4
Raw cavitation.By that analogy, can connect multiple Venturi tubes, form multi-level throttle.
When needing to study influence of the diameter of venturi 4 to cavitation, but one-level throttling is when being not reaching to expected cavitation effect,
The Venturi tube of two-step throttle can be now transformed into different specifications, so that change the venturi throat 4 of two-step throttle
Diameter.When needing to study influence of the sequencing of venturi 4 of different-diameter to cavitation, it is only necessary to change the string of Venturi tube
Connection order.
Because multiple Venturi tubes can connect, multi-level throttle is formed, the degree of pressure reduction is added, the effect of cavitation is more
Plus substantially；Venturi tube is influenceed smaller, the performance of equipment is more in experimentation by the way of threaded connection by the disturbance of water
It is stable；It is made up of inside Venturi tube contraction section, venturi, expansion segment, current streamline is smooth, reduces the energy loss of current；
The throat diameter of this kind of Venturi tube can have different specifications, and the Venturi tube series connection of different size can simulate different operating modes,
Drastically increase the scope of application of this kind of device.
This tandem Venturi tube cavitation apparatus is simple in construction, cavitation phenomenon is obvious, equipment performance is stable, with stronger
Applicability.
