Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
Embodiment one
Referring to figs. 1 through Fig. 3, for the multi-stage jet flow exhaust valve in the embodiment of the present invention one, the multi-stage jet flow exhaust valve in the present embodiment is located at the air inlet of common gas exhaust passage system.Described multi-stage jet flow exhaust valve includes the panel 100 being provided with exhaust outlet 110 and is located at the guide pipe 200 connected inside panel 100 and with exhaust outlet 110, is provided with fluidic generator 300 inside panel 100.
In the present embodiment, fluidic generator 300 includes three plates 310 that enclose the most horizontally arranged, and be positioned at inner side enclose plate 310 be directed to together with panel 100 pipe 200 enclose in, and enclose formation through hole 320.And three of fluidic generator 300 self enclose plate 310 and form through hole 330 and through hole 340.So, when gas flows through multi-stage jet flow exhaust valve, forming three strands of jets and discharge in through hole 320, through hole 330 and through hole 340, in so enclosing jet protective conduit, waste gas is not poured in down a chimney out by exhaust outlet 110 by guide pipe 200.It should be noted that the structure of fluidic generator 300 is not limited to the structure in the present embodiment, it also can arrange dividing plate in through hole 330 with through hole 340 and two through hole is divided into greater number of through hole.As long as ensureing when fluidic generator 300 encloses guide pipe 200; and a reserved jet via-hole between guide pipe 200; fluidic generator 300 self is provided with at least one through hole simultaneously; regardless of whether fluidic generator 300 the most why structure; it can at least form two jet via-holes and for air-flow discharge thus reach the effect of Multi-stage jet; be conducive to the discharge of waste gas, therefore meet the fluidic generator 300 of above-mentioned condition all within scope.
As shown in Figure 2, the bottom of through hole 330 and through hole 340 has air inlet 350, and top has gas outlet 360, and air inlet 350 is big, and gas outlet 360 is little.So, regulated by each through hole air inlet, gas outlet size ratio, change effluxvelocity, reduce the gas in pipelines normal pressure to exhaust outlet 110, even produce negative pressure, beneficially exhaust equipment and carry out waste gas discharge, efficiency is greatly improved, and save air draft power consumption, reduce air draft noise, more energy efficient, environmental protection.
With reference to Fig. 1; in the present embodiment; on fluidic generator 300, through hole 330 and through hole 340 enclose guide pipe 200 completely; i.e. on fluidic generator 300, through hole 330 and through hole 340 are all to produce jet in the both sides of guide pipe 200 and back; this form protected effect is best; it is of course also possible to only part encloses guide pipe 200.
In the present embodiment, the plate 310 that respectively encloses of fluidic generator 300 is both secured on panel 100.Can certainly be fixed on guide pipe 200.
In the present embodiment, fluidic generator 300 uses metal, plastics or slurry curing material to make.The above-mentioned various strength of materials, cost are different, can select according to actual needs.This metal can be simple metal material, it is also possible to alloy material.
In the present embodiment, enclose plate 310 bottom and can change the size of angular adjustment air inlet and fix (not shown) by screw, thus or obtain different size of air inlet 350.
In the present embodiment, fluidic generator 300 is fixedly connected on inside panel 100.Certainly, panel 100 can also be a part for discharge duct tube wall, and guide pipe 200 and fluidic generator 300 are fixed on discharge duct wall.
Embodiment two
With reference to Fig. 4, Fig. 5, for multi-stage jet flow exhaust valve in the embodiment of the present invention two.In the present embodiment, being: in the present embodiment in place of first embodiment main difference, the through hole 330 of fluidic generator 300 and through hole 340 only produce jet rather than enclose guide pipe 200 and produce jet at the back of guide pipe 200.And in embodiment one, fluidic generator 300 is all to produce three strands of jets in the both sides of guide pipe 200 and the back side.The present embodiment is weaker compared with embodiment one comparative effectiveness, but it can reduce the width of fluidic generator 300, advantageously reduces manufacturing cost.
Embodiment three
With reference to Fig. 6, Fig. 7, for multi-stage jet flow exhaust valve in the embodiment of the present invention three.The present embodiment and embodiment one, it is in place of the main difference of embodiment two: in the present embodiment, the cross section of guide pipe 200 is semicircle, fluidic generator 300 includes that two pieces enclose plate 310, respectively enclosing plate 310 and enclosing the cross section of formation is arc, wherein form a through hole between plate 310 and guide pipe 200 enclosing of inner side, two enclose and have a through hole between plate 310, so, when gas passes through multi-stage jet flow exhaust valve, secondary jets can only be produced, and the end face of the gas outlet 360 of fluidic generator 300 is concordant with guide pipe 200 upper port, and each gas outlet 360 of fluidic generator 300 raises successively in embodiment one with embodiment two, and higher than the upper port of guide pipe 200.
These are only presently preferred embodiments of the present invention, not in order to limit the present invention, all any amendment, equivalent and improvement etc. made within the spirit and principles in the present invention, should be included within the scope of the present invention.
