Description
Technical field
The present invention relates to fluid control field, particularly relate to a kind of can the variation and the fluid control device of automatic Compensation Regulation with input end and output terminal fluid parameter.
Background technique
Traditional fluid control technology mainly relies on various valve bodies to control and regulate every fluid parameter, and its control mode is mainly divided two kinds: manually control and electronic control.Its working principle all is to rely on the position of external force change spool with the useful area that the regulation valve body inner fluid passes through, and reaches the pressure of change output terminal fluid or the purpose of fluid parameters such as flow velocity or flow.
Control efficiency is low, the shortcoming of control weak effect but this controlling method but has inevitably.At first, because it relies on the motion of outside driving force control spool fully, spool itself can not be adjusted automatically with the variation of fluid parameter, so existing valve technology can't be according to the real-time change of fluid parameter and quick adjustment voluntarily; Secondly, existing valve technology all is that a kind of valve body only has the function of regulating a fluid parameter without exception, as pressure regulator valve, series flow control valve, and in the application of reality, every fluid parameter at runner two ends, as pressure, flow velocity or flow very complicated variation may take place simultaneously, in such complex work environment, this one-parameter control valve is difficult to adapt to actual needs.For example, in production reality, may when reducing delivery pressure, also need to keep or increase output flow, or one or more fluid parameters of input end or output terminal have continuous irregular variation, such as from fluid substance such as underground extraction water, oil or rock gases the time, the parameters that is positioned at underground fluid can't accurately be expected because correlative factor is complicated and changeable.Such working environment and requiring for traditional control valve body can only be formed complexity and huge valve system is finished by the valve body of enormous amount, will certainly increase the cost and the maintenance of valve system so greatly and operate the cost of this system.
Occur a kind of utilization at present and be arranged at the method and apparatus that mobile plate in the air channel is regulated blast, wind speed and air quantity automatically.Its control principle is, one hinged regulator plate is set in the air channel, this regulator plate can be swung under the effect of the stream pressure in the air channel of flowing through automatically to keep the balance of regulator plate gravity and suffered wind-force, when the flow parameter at two ends, air channel changes, air-flow also can correspondingly change at the active force of this regulator plate, so the automatic swing of regulator plate meeting is to keep balance again, change in location along with regulator plate, space, cross section between regulator plate and the air channel also changes, the passing capacity that is the air channel changes, thereby can reach the purpose of automatic adjusting output terminal fluid parameter.
Summary of the invention
The object of the present invention is to provide a kind of novel fluid control device that can regulate the output terminal relevant parameter according to the variation of runner two ends parameter automatically with new technical conceive, the present invention is simple and reasonable, adapt to wide, the control effect is remarkable, utilize fluid control device of the present invention quick adjustment output flow rate of fluid, pressure and flow automatically, have very wide application prospect.
Technological scheme of the present invention is as follows:
Automatic compensation controller for fluid, comprise runner, it is characterized in that: be provided with in the described runner can this runner axial direction moves in the fluid force lower edge controlling device, and the cross section difference between described runner and the controlling device changes with moving of this controlling device, and described controlling device produces the active force that balances each other with suffered fluid force in this moving process.
Described flow path wall is provided with one or more perforation runners inside and outside adjustment hole or groove.
Described adjustment hole or groove longitudinally are uniformly distributed on the flow path wall.
Described runner is the bend pipe structure that is obliquely installed.
Described bend pipe structure has the caliber of gradual change.
Described controlling device is rolling element or the slide mass that is arranged in the runner.
Described rolling element is ball or roller.
Described slide mass is a slide block.
The active force that balances each other with suffered fluid force that described controlling device produces in its moving process is gravity or elastic-restoring force or magnetive attraction or its combination.
Technique effect of the present invention is:
The present invention is by being provided with controlling device in runner, this controlling device can move under the fluid force effect and move with this and produce the active force that balances each other with suffered fluid force, and the cross section difference between described runner and the controlling device changes with moving of this controlling device.
When the parameter at the runner two ends changes, will certainly influence the suffered active force of controlling device that is positioned at runner, can move at the effect lower edge of fluid runner owing to controlling device simultaneously, therefore change in location takes place in controlling device under the effect of this active force, thereby cause the cross section difference between runner and the controlling device to change, just can correspondingly influence the fluid parameter at runner two ends conversely.
Fluid control device of the present invention has the bidirectional modulation function.When runner input end fluid parameter changes, controlling device in the runner is moved under the effect of fluid, and along with this moves, cross section difference between runner and the controlling device changes, thereby make the practical tonnage capacity of runner change, and influence the parameters of the fluid of output terminal; Conversely, when the fluid parameter of runner output terminal changes, can produce the change in location of controlling device equally, make the passing capacity of runner change, and influence each relevant parameter of the fluid of output terminal.
For example, adopt vertical plane tilt be provided with on the less horn-like bend pipe structure of end section, controlling device is the ball that can move freely that is arranged in this bend pipe, fluid flows into from the lower end oral area of bend pipe, and is flowed out by the upper end oral area.
When input end pressure or flow velocity change, fluid force suffered on the ball is strengthened, ball moves to the bend pipe rear end with fluid, and in a certain position, spheroid gravity will balance each other with the active force of fluid, spheroid stops to move, at this moment, cross section difference between bend pipe and spheroid reduces, the passing capacity of fluid a little less than, the isoparametric variation tendency diminuendo of the pressure of output terminal and flow velocity as long as suitably adjust the caliber difference in change of bend pipe front end and back end, just can keep the pressure of output terminal, parameter such as flow velocity or flow is constant or keep parameters variation tendency as required to regulate voluntarily.
On the contrary, when every fluid parameter of output terminal changes, the suffered pressure reduction in spheroid two ends also can correspondingly change, and the fluid force that spheroid is subjected to also will change, and spheroid equally also can be moved till being positioned at new equilibrium position at fluid effect lower edge runner.Such as, when output terminal causes outlet pressure decline, flow attenuating owing to a variety of causes such as obstructions, the suffered pressure reduction of spheroid reduces, be that suffered fluid force reduces, it moves to input end under the effect of gravity, thereby cause the cross section difference between bend pipe and spheroid to increase, the fluid passing capacity strengthens, the flow of output terminal, pressure and other parameters increase, not smooth to overcome the runner that causes owing to reasons such as obstructions, can guarantee that stable or each parameter variation tendency as required of each parameter of fluid of output terminal is regulated voluntarily.
Can't effectively utilize under the situation of spheroid self gravitation for those, as runner for being horizontally disposed with or fluid flows downward in runner, this moment, controlling device can utilize elastic-restoring force or magnetive attraction to reach the purpose that balances each other with fluid force, as controlling device is spheroid, between this spheroid and runner, be provided with elastic structure or magnetic pole, spheroid is moved under the influence of fluid force, this elastic structure or magnetic pole produce elastic force or the magnetive attraction opposite with this fluid force, reach new balance to impel spheroid.
Certainly, for different flow passage structure modes, the concrete adjusting effect that the present invention played also has nothing in common with each other, but its total technical conceive is always by controlling device moving in runner, makes the corresponding purpose that changes and influence the every fluid parameter of output terminal to reach of cross section product moment between runner and controlling device.
In addition, the present invention's flow path wall is provided with adjustment hole or groove, by controlling device moving in runner, the adjustment hole number and the area that are positioned at the controlling device both sides all change thereupon, and the adjustment hole that is positioned at the controlling device outlet side so also will effectively play the effect of regulating output flow and flow velocity and pressure.
By above-described regulation mechanism as can be seen, control gear of the present invention both can change and reaction automatically with the fluid parameter of input end, also can change and reaction automatically with the fluid parameter of output terminal, and had the extremely good characteristic that is quick on the draw; The result is not only relevant with the structure of runner for its adjusting of controlling device of the present invention, also be arranged at flow path wall on the useful area of adjustment hole relevant, also change relevant simultaneously with each parameter of input end and output terminal, so can reach the purpose that flow velocity, pressure and flow are exported in effective adjusting by regulating each relevant parameter, so the present invention has, and regulation range is wide, mean of calculating abundant, the regulative mode flexible characteristic.
That controlling device of the present invention also has is simple in structure, simple installation, with low cost, service-strong advantage.

Embodiment
The present invention will be further described below in conjunction with embodiment.
Be illustrated in figure 1 as the structural representation of one embodiment of the invention.
Runner 1 is a horn-like bend pipe structure, the one end is import 4, the other end is outlet 5, around the tube wall of runner 1, evenly be provided with adjustment hole 6, be provided with roller 3 in runner 1 inner chamber, but roller 3 longshore current roads 1 internal chamber wall freely rolls, and is provided with baffle plate 7 at import 4 oral areas, to prevent that roller 3 is by tumbling in the runner 1.
At first, because runner 1 is the horn-like bend pipe structure that entrance point is big, outlet end is little, when passing to fluid in the runner 1, roller 3 is in a certain equilibrium position, and himself gravity and suffered fluid force balance each other.
When the pressure of import 4 ends or flow velocity increase, roller 3 suffered fluid force also increase thereupon, and the effect lower edge of this fluid force runner 1 to the outlet 5 directions move, because runner 1 top bore is little, space between roller 3 and the runner 1 reduces with moving of roller 3, and the effective discharge area of runner 1 inner fluid is also corresponding to be reduced, and fluid increases through the pressure loss that roller 3 produces, so it is stable that the outlet pressure of fluid keeps, and can not increase with entrance point pressure.
When the pressure of import 4 ends or flow velocity reduce, roller 3 suffered fluid force also reduce thereupon, roller 3 moves to import 4 directions at the effect lower edge of self gravitation runner 1, because runner 1 below bore is big, space between roller 3 and the runner 1 increases with moving of roller 3, the also corresponding increase of the effective discharge area of runner 1 inner fluid, and fluid reduces through the pressure loss that roller 3 produces, it is stable that the outlet pressure of fluid still keeps, and can not reduce and reduce with entrance point pressure.
Yet, in reality production reality, also have owing to various former thereby cause the unstable situation about changing of outlet end fluid parameter, for example in the wind-force feeder, exhaust outlet causes the load variations of outlet end owing to the variation of solid accumulation amount, when solid accumulation more for a long time, the outlet end load is big, this moment, outlet end stopped up, and correspondingly the pressure reduction that is produced on the roller 3 reduces, and roller 3 will move to import 4 directions under action of gravity, space between roller 3 and the runner 1 increases with moving of roller 3, the also corresponding increase of the effective discharge area of runner 1 inner fluid, the flow with the end of increasing export improves the feeding ability; And when material supply is not enough, the outlet end load is little, the pressure reduction that is correspondingly produced on the roller 3 increases, roller 3 will move to outlet 5 directions under the fluid effect, space between roller 3 and the runner 1 reduces with moving of roller 3, the effective discharge area of runner 1 inner fluid is also corresponding to be reduced, and to reduce the flow of outlet end, restriction feeding ability is to avoid the unnecessary consumption of fluid.
Secondly, because runner 1 tube wall is provided with a large amount of adjustment hole 6, the adjustment hole 6 that wherein is positioned at roller 3 outlet sides will effectively be exported fluid, when roller 3 longshore current roads 1 move, the gross area of the adjustment hole 6 of its outlet side will change thereupon, promptly also will change thereupon, can play the purpose of regulating and improving output flow by the fluid total volume that exports 5 outputs.
In the present invention, roller 3 also can be replaced by structures such as slide blocks, and adjustment hole 6 can be replaced by the groove structure that is arranged on the tube wall.Described groove structure can have any shape.
Can't effectively utilize under the situation of spheroid gravity for those, as runner for being horizontally disposed with as shown in Figure 2, or fluid flows downward in runner as shown in Figure 3, this moment, controlling device can utilize elastic-restoring force or magnetive attraction to reach the purpose that balances each other with fluid force, be made as slide block as controlling device, between this slide block and runner, be provided with spring 8, slide block is moved under the influence of fluid force, this spring 8 produces the elastic force opposite with this fluid force thereupon, reaches new balance to impel slide block.
Certainly, the magnetic pole that also can utilize correspondence to be arranged between slide block and runner produces the magnetive attraction opposite with fluid force, to replace or to impel slide block to reach new balance in conjunction with described elastic-restoring force.
Fluid of the present invention comprises working medium such as various liquid phases, gas phase or other little viscosity fluidised form.
The above is a preferred implementation of the present invention only, should be pointed out that for a person skilled in the art, can also make a lot of modification and improvement according to spirit of the present invention and essence, but these modification and improvement all will fall into protection scope of the present invention.
