Abstract

The present invention relates to a fluid metering device, and more specifically, the inlet pipe 100 by installing a circular rubber pad 130 formed with a flow path 120 in the center between the inlet pipe 100 and the outlet pipe 110. The circular rubber pad 130 is compressed in proportion to the pressure by the pressure of the fluid flowing into the pressure and the central flow path 120 in the inlet pipe 100 is reduced to automatically adjust the flow rate

Description

      Fluid metering device {CONSTANT FLOW DEVICE}

The present invention relates to a fluid metering device, and more particularly, to a fluid metering device to automatically adjust the flow rate to the fluid itself pressure.

By using the formula (flow rate = pipe diameter x flow rate) and applying a pressure, a rubber pad that is deformed is applied to make a flow path hole in the center, and the flow path becomes smaller in proportion to the water pressure applied. Will get

In general, the flow of fluid in the pipe of the same diameter increases the flow rate when the pressure is high and the flow rate is low when the pressure is low.In the case of water supply pipe or district heating pipe, there is a difference in water pressure depending on the location and altitude of each household. In the case of heating, the pressure difference is caused by many pipes, so constant water supply and heating were not possible.

 By using the formula (flow rate = pipe diameter x flow rate) and applying a pressure, a rubber pad that is deformed is applied to create a flow path hole in the center to make the flow path smaller in proportion to the pressure applied, and the flow rate becomes faster in proportion to the increased pressure. Will get

Even if the hydraulic pressure is different for each pipe, the rubber pad of the present invention is inversely proportional to each other by the rubber pad of the present invention and automatically adjusted to obtain the same flow rate.

The present invention for achieving the above object will be described in detail with reference to the accompanying drawings, FIGS. 1, 2 and 3.

1 is an exemplary view showing a state in which the present invention is installed, the fluid does not flow

Figure 2 is an exemplary view showing a state in which the fluid flows and the pressure is applied to the present invention in cross section

Figure 3 is an exemplary view showing in a cross-sectional view a state in which the pressure of the fluid rises higher pressure is applied.

The principle of the present invention works in the absence of pressure as shown in Figure 1 in the central flow path 120 maintains the maximum diameter, but as the fluid flows the water pressure rises as shown in Figure 2 rubber pad 130 outlet 110 Pressed in the direction of) and the central flow path 120 is reduced and as the pressure increases, the rubber pad 130 is pressed more as shown in FIG. 3 and the flow path 120 is further reduced.

Then, the flow rate should decrease as the flow path 120 becomes smaller, but the formula

(Flow rate = area X flow rate)

The flow path 120 is reduced by as much as the pressure goes up as in the flow rate but the flow rate is increased by the increased water pressure, the flow rate is always constant compared to the above formula.

As a result, water and heating imbalances, which appear to be high and low in water pressure according to generation altitude and location in water supply or district heating, are resolved.

Because the flow path is reduced at high pressure, the supply volume is maintained at the proper level, and at low pressure, the flow path is wide, but the flow rate is slowed and the supply volume is generally constant.

In the case of individual heating, the heating imbalance occurs due to the flow of fluid to one pipe during heating of each room. However, if this bill is installed, the heating water is equally supplied to each room to achieve equal heating.
