Detailed description of the invention

Fig. 1 is the structural schematic diagram of the adjustable jet flow device of the utility model embodiment.

Specific embodiment

Technical solutions of the utility model are described in detail below with reference to embodiment.

As shown in Figure 1, the adjustable jet flow device of the utility model embodiment includes intake chamber 1, induction chamber 2, diffuser 3 And component is adjusted, intake chamber 1, induction chamber 2 and 3 three of diffuser are sequentially communicated connection, and intake chamber 1, which has, adjusts port 11 and spray Liquid port 12 adjusts the other end that port 11 is located at intake chamber 1 with respect to hydrojet port 12, adjusts and inserts at component self-regulation port 11 It can move back and forth in intake chamber 1 and in intake chamber 1, intake chamber 1 is inserted in induction chamber 2 by helicitic texture, is passed through Intake chamber 1 is rotated, to adjust the distance between hydrojet port 12 and diffuser 3.In other embodiments, it is removable that other can be used Dynamic mode.Hydrojet port 12 can move back and forth in induction chamber 2, and induction chamber 2 is connected through a screw thread with diffuser 3, certainly Other detachably connected modes can also be used.The side wall of intake chamber 1 is outward extended with inlet tube 4, and induction chamber 2 is equipped with air-breathing Pipe 5 passes through 3 mixing liquid of diffuser and gas.

Adjusting component is needle valve structure, mainly includes valve handle 51 and spool 52, and the head of spool 52 is arranged to spherical surface, In other embodiments, it may be designed as other shapes, such as ellipsoid, but according to fluid mechanics principle, spherical surface is practical new at this Effect is best in type technical solution.Spool 52 is fixed on valve handle 51, and valve handle 51 is able to drive spool 52 and is moved, valve handle 51 It is adapted with port 11 is adjusted, by adjusting the position of valve handle 51 come the position of adjusting spool 52.The head of spool 52 can into Axial movement, longest may extend in hydrojet port 12 in liquid chamber 1, and the effect of the position of adjusting spool 52 is, adjust spray Area of passage at liquid port 12.In the present embodiment, by rotation valve handle 51 adjust valve handle 51 adjust port 11 position, To 52 position of adjusting spool.It in other embodiments, can also be by applying pulling force or the fortune of press belt movable valve plug 52 to valve handle 51 It is dynamic, come the position of adjusting spool 52.

Valve handle 51 is equipped with scale, to show the mobile distance of valve handle 51, to find the flow-passing surface at nozzle ports 12 The long-pending corresponding relationship with scale, it is subsequent the area of passage at nozzle ports 12 accurately to be adjusted by scale.

It is equipped with gasket 6 between valve handle 51 and adjusting port 11, gasket 6 is sealed intake chamber 1, prevents leakage.

To be threadedly coupled between hydrojet port 12 and induction chamber 2, by intake chamber 1 clockwise or counterclockwise, thus It realizes and the distance between hydrojet port 12 and diffuser 3 is adjusted.

It is connected through a screw thread between induction chamber 2 and diffuser 3, convenient for timing maintenance and replacement, in other embodiments, Other detachable or non-removable connection types can be used, such as be bolted, weld.

In the present embodiment, if there are two inlet tube 4 and the symmetrical side wall for being distributed in intake chamber 1, inlet tube 4 and feed liquors Angle between room 1 is 45 °, and this gives optimal structural parameters, in other embodiments, the quantity of inlet tube 4 And position is not construed as limiting, the angular range between inlet tube 4 and intake chamber 1 is greater than 20 ° and less than 70 °, according to actual stream Body operating condition is determined, to realize optimal technological effect.

Explanation is further explained to the technical solution of the utility model below by way of specific implementation process:

Make between hydrojet port 12 and diffuser 3 there are certain distance and fix, leads to by certain flow rate into inlet tube 4 Enter liquid to be mixed, liquid to be mixed enters intake chamber 1 by inlet tube 4, then adjusts hydrojet port 12 using screw thread and expands The distance between separate tube 3, while the area of passage at hydrojet port 12 is adjusted by rotating valve handle 51, in the mistake of adjusting Optimal the amount of gas inhalation is looked in journey, makes the stable water pressure sprayed, to obtain the optimised process of ejector under current working Parameter.

The adjustable jet flow device of the utility model can be achieved at the same time area of passage and spray at ejector nozzle ports The distance between mouth port and diffuser are adjusted, and quickly find the best ejector setting condition under current fluid operating condition, It realizes optimised process effect, and adapts to the variation of fluid flow, without being replaced to ejector.

Specific embodiment of the utility model is described in detail above, it should be understood that those skilled in the art without It needs creative work according to the present utility model can conceive and makes many modifications and variations.Therefore, it is all in the art Technical staff passes through logical analysis, reasoning, or a limited experiment according to the design of the utility model on the basis of existing technology can It, all should be within the scope of protection determined by the claims with obtained technical solution.
