Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flow control unit having a plurality of flow control pieces having different slopes,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flow rate control unit having a plurality of flow rate control pieces having different slopes and, more particularly, to a flow rate control unit having flow rate control units having different slopes for reducing fluctuation of a flow rate of a fluid To a flow rate control unit having a plurality of flow rate control pieces.

Generally, the tap water used in each household differs depending on the installed position of the water supply equipment even when the water pipe of the same size is used, because the difference in the position of the water tank and the gap between the water tank and the water supply equipment The water pressure and the discharge amount flowing through the water pipe become different, and in the case of the old water pipe, the discharge amount becomes different due to the foreign substance such as the scale inside.

Since the above-described water pressure is proportional to the size of the water pipe and the amount of water that can be discharged within a limited time, a small amount of water is discharged within the same time in a water pipe having a low water pressure, A large amount of water is discharged.

Therefore, in a low-rise building of a high-rise building or a high-rise apartment, a part of the discharge amount is wasted due to a water pressure that is higher than necessary.

In view of such problems, a flow rate regulating device for measuring the water pressure in the water pipe to reduce the cross-sectional area inside the water pipe to match the discharge amount is used. Because it regulates the flow rate by controlling the area irrespective of the water pressure inside the water pipe, many kinds of flow rate control devices required according to the size of the water pipe and the water pressure should be manufactured and visit each household to check the size of the water pipe, The valve is disassembled and a specific flow rate regulating device is mounted. Therefore, it takes a lot of manpower and time to install the flow rate regulator.

It is to be understood, however, that the appended drawings illustrate the present invention in order to more easily explain the present invention, and the scope of the present invention is not limited thereto. You will know.

In describing the embodiments of the present invention, it is to be noted that elements having the same function are denoted by the same names and numerals, but are substantially not identical to elements of the prior art.

Also, the terms used in the present application are used only to describe certain embodiments and are not intended to limit the present invention.

FIG. 1 is a view illustrating a flow control unit having a plurality of flow control pieces having different slopes according to an embodiment of the present invention.

As shown in FIG. 1, the flow rate control unit provided on the flow path according to an embodiment of the present invention may be installed on the flow path 10a. 1, the flow path 10a of the water supply device 10 is illustrated as an example of the flow path 10a. However, the present invention is not limited thereto and may be applied to any flow path where the fluid flows. FIG. 3 is a cross-sectional view of a flow control unit including a plurality of flow control pieces having different slopes according to an embodiment of the present invention. FIG. It is a perspective view.

Hereinafter, a flow rate control unit having a plurality of flow rate control pieces having different slopes according to an embodiment of the present invention will be described with reference to FIGS. 2 and 3. FIG.

As shown in FIGS. 2 and 3, the flow rate control unit having a plurality of flow rate control pieces having different slopes according to an embodiment of the present invention may include a plate 100 and a flow rate control piece 110 .

The plate 100 may be disposed perpendicular to the flow direction of the fluid in the flow path 10a. The plate 100 may have at least one fluid passage hole 120 through which the fluid passes.

Here, the fluid is not limited to water but is used to include liquids such as water and oil, and gases such as air and oxygen.

The plate 100 may be formed in a circular shape and may have a predetermined thickness. The thickness of the plate 100 may be determined in consideration of the hydraulic pressure or the cross-sectional area of the fluid flowing through the flow path to which the plate 100 is applied, and the thickness of the plate 100 applied to the oil pressure- have.

As the material of the plate 100, metal or synthetic resin having corrosion resistance can be applied, but the present invention is not limited thereto.

A plurality of the flow rate regulating pieces 110 may be provided at positions corresponding to the fluid passing holes 120. The flow rate regulating pieces 110 may be inclined with respect to the plate 100 in a direction in which the fluid flows, . At least two of the plurality of flow rate adjusting pieces 110 may form different slopes from the plate 100.

Also, the flow rate adjusting member 110 can be pressed by the hydraulic pressure of the fluid to adjust the opening of the fluid passing hole 120. As a result, the fluctuation range of the flow rate is narrowed, so that the water saving effect can be expected.

For example, when the flow rate of the fluid flowing through the flow path 10a is increased to increase the flow rate, the pressure for pressurizing the flow rate regulating element 110 is increased. As a result, So that the opening between the flow rate adjusting member 110 and the plate 100 can be narrowed. Accordingly, the flow rate passing through the fluid passing hole 120 is reduced, and as a result, the flow rate discharged through the water supply device to the outside can be smaller than the flow rate flowing in the flow path 10a.

Alternatively, if the flow rate of the fluid flowing through the flow path 10a is decreased and the flow rate is lowered, the pressure of the fluid pressurizing the flow rate adjusting flap 110 is relatively lowered. Accordingly, The fluid passing hole 120 between the flow rate controlling member 110 and the plate 100 may be wider than in the above case. Accordingly, the flow rate passing through the fluid passing hole 120 becomes large, and as a result, the flow rate discharged to the outside through the water supply device can be relatively increased.

The fluctuation range of the flow rate discharged to the outside through the water supply equipment is narrowed by the above-described principle, and the water saving effect can be obtained.

The area of the flow rate regulating piece 110 corresponds to the cross sectional area of the fluid passing hole 120 but the area of the flow rate regulating piece 110 is larger than the cross sectional area of the fluid passing hole 120 May be formed small.

In one embodiment of the present invention, the flow rate adjusting member 110 may be formed by forming a fluid passage hole 120 by cutting a portion of the plate 100 from the plate 100 and bending toward the fluid inlet side to form a slope with respect to the plate 100 . That is, the plate 100 and the flow rate controlling member 110 may be integrally formed. As a result, the water saving effect can be obtained with a minimum number of components.

When the plate 100 and the flow rate adjusting piece 110 are integrally formed as in the present embodiment, the material of the plate 100 is a material having an elastic force and a restoring force. The flow rate adjusting piece 110 is made of The inclination with respect to the plate 100 is reduced, and when the oil pressure is removed, the inclination with respect to the plate 100 is increased and can be restored to its original state.

Alternatively, although not shown in the figure, the flow rate regulating piece 110 may be coupled to the plate 100 as a separate member.

The flow rate regulating piece 110 can be joined to the plate 100 by welding. Even when the flow rate regulating piece 110 is provided as a separate member, the flow rate regulating piece 110 may have a predetermined inclination with respect to the plate 100. [ When the flow rate adjusting member 110 is pressurized by the hydraulic pressure, the opening of the fluid passing hole 120 is narrowed by tilting toward the side closer to the plate 100. When the hydraulic pressure applied to the flow rate adjusting member 110 is removed, It can be restored to its original state.

The area of the flow rate regulating piece 110 is larger than the sectional area of the fluid passing hole 120 so that the flow rate regulating piece 110 is supported on the plate 100 around the fluid passing hole 120, Can be limited.

4 is a cross-sectional view of a flow rate control unit having a plurality of flow rate control pieces having different slopes according to an embodiment of the present invention.

As shown in FIG. 4, in one embodiment of the present invention, the slopes of the plurality of flow rate adjusting pieces 110 with respect to the plate 100 may be different from each other. Thus, the opening degree can be gradually narrowed from the fluid passage hole 120 corresponding to the flow adjusting member 110 having a small inclination with respect to the plate 100, that is, a large projection area.

Here, the projected area refers to the area of a shadow formed on the plane of the rear when a parallel light ray is projected on an object. In this embodiment, the projected area of the flow rate adjusting piece 110 may be perpendicular to the moving direction of the fluid.

In the present embodiment, the flow rate control unit including a plurality of flow rate control pieces having different inclination angles includes three flow rate control pieces 110 and fluid through holes 120 as an example.

For convenience of explanation, the flow rate adjusting piece having the largest slope with respect to the plate 100 is referred to as a first flow rate adjusting piece 110a, and the second flow rate adjusting piece 110a is arranged in ascending order as the slope with the plate 100 becomes smaller 110b, and a third flow rate regulating element 110c. That is, since the angle between the first flow rate adjusting plate 110a and the plate 100 is larger, the angle formed by the first flow rate adjusting plate 110a and the plate 100 is

Figure 112014021777946-pat00001
The angle between the second flow rate regulating piece 110b and the plate 100 is
Figure 112014021777946-pat00002
The angle between the third flow rate regulating piece 110c and the plate 100 is

In other words,

The corresponding fluid passing holes are referred to as a first fluid passing hole 120a, a second fluid passing hole 120b and a third fluid passing hole 120c, respectively.

In the case where the pressure is the same, the force acting on the flow rate adjusting member 110 becomes larger as the projection area becomes larger. When the areas of the flow rate adjusting members 110 are all the same, the smaller the angle formed with the plate 100, The third flow rate regulating piece 110c having the smallest slope with respect to the first flow rate regulating piece 110c has the largest force and accordingly the third flow rate regulating piece 110c can be tilted by the greatest angle. On the contrary, since the first flow rate adjusting piece 110a having the largest slope from the plate 100 has the smallest force, the first flow rate adjusting piece 110a can be tilted to the smallest angle.

As described above, the slopes of the plate 100 and the plurality of flow rate adjusting pieces 110 are formed differently, and the opening of the fluid passing holes 120 is gradually narrowed in accordance with the inclination, Can receive the same force to prevent all of the fluid through holes 120 from being simultaneously closed.

As described above, the opening degree of the fluid passage hole 120 is gradually adjusted by the flow rate or the flow rate of the fluid flowing in the flow passage 10a, whereby a proper amount of flow rate can be discharged to improve the flow rate.

Although the fluid passing holes 110 are formed in the same area in this embodiment, the areas of the fluid passing holes 110 may be different from each other.

FIG. 5 is a view illustrating a bypass flow path formed in a plate of a flow rate control unit having a plurality of flow rate control pieces having different slopes according to an embodiment of the present invention. FIG.

As shown in FIG. 5, a bypass flow path 130 may be formed at one side of the plate 100 to prevent the flow of fluid from being blocked.

When the elasticity of the flow rate adjusting member 110 is lowered over time and the slope between the plate 100 and the flow rate adjusting member 110 becomes smaller, the opening of the fluid passing hole 120 becomes narrower, Can be reduced. Alternatively, if the flow control member 110 is horizontal to the plate 100 and the fluid can not pass therethrough, the water supply device 10 may be damaged. Therefore, it is possible to prevent the flow of the fluid from being blocked by forming the bypass flow path 130 through which the fluid can always pass.

FIG. 6 is a view illustrating a flow control unit having a plurality of flow control pieces having different slopes according to an embodiment of the present invention.

As shown in FIG. 6, a stopper 300 for restricting a tilting angle of the flow rate adjusting member 110 may be provided at the rear of the plate 100. When a very strong pressure suddenly acts on the flow rate adjusting member 110, there is a possibility that the flow rate adjusting member 110 tilts more than the inclination with respect to the plate 100. Therefore, in order to prevent this, a stopper 300 may be provided on the rear side of the plate 100.

6, the stopper 300 may be formed such that a mesh is applied to a portion corresponding to the fluid passage hole 120 to allow the fluid to pass therethrough, but the tilt angle of the flow rate control member 110 is limited. Though not shown, may be a pin provided to cross the fluid passage hole 120. [

The stopper 300 is not limited to the one described above, and any material may be used as long as the fluid can flow normally but restrict the tilting angle of the flow rate controlling member 110.

A plurality of flow rate control units having a plurality of flow rate control pieces having different inclination according to the embodiment of the present invention are provided on the flow path 10a so as to be spaced apart from each other to greatly reduce the fluctuation range of the flow rate of the fluid discharged to the outside .

The flow rate control unit having a plurality of flow rate control pieces having different slopes according to the present embodiment may be installed directly on the flow path 10a or may be provided on the flow path 10a with a plurality of flow rate control pieces having different slopes An adapter for installing the adjustment unit may be separately provided.

FIG. 7 is a plan view of a flow rate control unit including a plurality of flow rate control pieces having different slopes according to another embodiment of the present invention. FIG. 8 is a cross- And Fig.

Hereinafter, a flow rate control unit having a plurality of flow rate control pieces having different slopes according to another embodiment of the present invention will be described with reference to FIGS. 7 and 8. FIG.

7 and 8, the flow rate control unit having a plurality of flow rate control pieces having different slopes according to another embodiment of the present invention may include a plate 100 and a flow rate control piece 110 have.

The description of the same configuration as that of the embodiment of the present invention will be omitted.

However, according to another embodiment of the present invention, the flow rate control unit having a plurality of flow rate control pieces having different slopes may have four or more even numbered flow rate control units, The flow rate adjusting pieces 110 facing each other may be formed to have the same slope as the plate 100.

In the present embodiment, four fluid passage holes 120 are formed as an example. The slopes of the first flow rate regulating piece 110a and the second flow rate regulating piece 110b with respect to the plate 100 are equal to each other And the slopes of the third flow rate regulating piece 110c and the fourth flow rate regulating piece 110d with respect to the plate 100 are formed to be equal to each other and disposed to face each other.

That is, the angle formed between the first flow rate regulating piece 110a and the plate 100 is

Figure 112014021777946-pat00005
The angle between the second flow rate regulating piece 110b and the plate 100 is

Thus, since the hydraulic pressures acting on the flow regulating pieces 110 opposed to each other are the same and the closing speeds are the same, the hydraulic pressures acting on both sides of the plate 100 are the same and the flow rate and the hydraulic pressure are concentrated on one side of the plate 100 Can be prevented. Thus, deformation, breakage, and the like of the plate 100 can be prevented.

It will be apparent to those skilled in the art that the present invention can be embodied in other specific forms without departing from the spirit or scope of the invention as defined in the appended claims. It is obvious to them.
