Description
Technical field
The utility model relates to dynamic flow balancing assembly, belongs to technical field of valve control.
Background technique
Current flow balance valve is by the area of passage of automatic change spool, adapts to pressure before and after valve and change, and controls by valve flow.Automatic flow control valve is actually a kind of constant flow rate valve that flow is constant that keeps, when the modulating valve of some end-equipment in system (as fan coil unit or new blower fan group etc.) is along with the variation of load regulates and while causing in pipe network that pressure changes, the flow of other end-equipments remained unchanged.According to the difference of setting flow mode, automatic flow control valve can be divided into firm discharge type and two kinds of fixed flow discharge types are established at scene, but in actual working procedure, particularly in the larger variable flow system of system loading fluctuation, due to the fluctuation of inlet outlet pressure differential, cause the control characteristic variation of flow balance valve, control accuracy reduces, and the ability of opposing system interference is poor.
Summary of the invention
The utility model provides dynamic flow balancing assembly, to solve existing dynamic flow balance valve control characteristic variation in the larger variable flow system of system loading fluctuation, control accuracy reduces, the poor problem of ability of opposing system interference, the utility model adopts following technological scheme for this reason:
Dynamic flow balancing assembly, comprise electric actuator, valve body and pipe collar, the two ends of valve body are set to respectively entrance channel and outlet flow, described valve body comprises Flow valve stamen cylindrical shell, spring and valve courage, the first end of spring is fixedly connected with one end of Flow valve stamen cylindrical shell, the second end of spring is fixedly connected with one end of valve courage, and electric actuator is connected by the first end of pipe collar, and the second end of pipe collar is fixedly connected with one end of valve body.
The dynamic flow balancing modular construction that the utility model mode of execution provides is simple, and the required pressure reduction of startup work is little, and through-current capability is large, cheap for manufacturing cost, is applicable to large-scale mass production.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technological scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment who obtains under creative work prerequisite, all belong to the scope of the utility model protection.
The utility model embodiment provides a kind of dynamic flow balancing assembly, as Figure 1-4, comprise electric actuator 1, valve body 2 and pipe collar 3, the two ends of valve body 2 are set to respectively entrance channel and outlet flow, described valve body 2 comprises Flow valve stamen cylindrical shell 22, spring 23 and valve courage 24, the first end of spring 23 is fixedly connected with one end of Flow valve stamen cylindrical shell 22, the second end of spring 23 is fixedly connected with one end of valve courage 24, electric actuator 1 is connected by the first end of pipe collar 3, and the second end of pipe collar 3 is fixedly connected with one end of valve body 3.
As optionally, described valve body 2 can adopt casting copper alloys.Described electric actuator 1 can employing be organized hot ABS, and wherein ABS is the copolymer of acrylonitrile (A), butadiene (B) and vinyl benzene (S), and this electric actuator 1 can be Siemens GLB ... the ball valve actuator of 9 series.Described spring 23 can adopt stainless steel material, and described valve courage 24 can adopt casting copper alloys.
Particularly, as shown in Figure 2 and Figure 4, in the time that system pressure difference is less than or equal to minimum value or system pressure difference and is more than or equal to maximum value, described Flow valve stamen cylindrical shell 22 is realized the effect of throttling plate hole, in the suitable place of pipeline, aperture is diminished, when liquid is through reducing, a fluid stream can attenuate or shrink.In the time that system pressure difference is between minimum value and maximum value, Flow valve stamen cylindrical shell 22 utilizes spring action to adjust orifice plate flow area according to the variation of pressure reduction, so that flow control is in nominal error scope.Described maximum value and minimum value are determined according to the designing requirement of system.
The dynamic flow balancing modular construction that the utility model mode of execution provides is simple, and the required pressure reduction of startup work is little, and through-current capability is large, cheap for manufacturing cost, is applicable to large-scale mass production.This dynamic flow balancing assembly not only has the motorized adjustment effect of traditional dynamic flow balance valve, carry out adjust flux by the opening and closing of controlling mortor operated valve, also there is the effect of transient equiliblium, flow can maintain all the time electric two-way valve open in the time that system pressure fluctuates time remains unchanged, thus avoided as traditional electric two-way valve system during in operation at part load state because pressure surge makes greatly the water flow fluctuation of carrying larger.Electrodynamic balance Twoway valves comprises the ball valve body being installed in ball valve body runner and the angle distance electric executor being connected with ball valve body, Intelligent dynamic balanced electric two-way valve structure technique of the present utility model is simple, startup operating pressure differential is little, through-current capability large, long service life, cheap for manufacturing cost, be applicable to large-scale mass production, in the time being applied to air-conditioning or heating network water system, its synthesis energy saving effect is fairly obvious.In the utility model, flow equilibrium and electronic control are integrated, closing force is up to 6.8bar, wide pressure differential range inner coil pipe water flow high precision in control is constant, when operation, noise is low, install and dismantle the very convenient obvious hydrodynamic noise that reduces water system, thoroughly solve hydraulic equilibrium problem, synthesis energy saving effect is remarkable.
The above; it is only preferably embodiment of the utility model; but protection domain of the present utility model is not limited to this; any be familiar with those skilled in the art the utility model embodiment disclose technical scope in; the variation that can expect easily or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claim.
