[0024] The present application is further described with reference to the accompanying drawings:

[0025] A volumetric metering device, characterized by comprising a box 10, a liquid storage mechanism I and a liquid storage mechanism II;

[0026] The box body 10 is provided with a control panel 14, and the box body 10 is provided with a liquid storage mechanism I121, a liquid storage mechanism II122, a support plate 17, a water inlet pipe 211 and a water outlet pipe 212;

[0027] The liquid storage mechanism I121 and the liquid storage mechanism II122 are arranged on the support plate 17;

[0028] The liquid storage mechanism I121 and the liquid storage mechanism II122 both include a measuring container 11, a liquid level sensor 13 and a weighing device 16; the weighing device 16 connected to the inner cavity of the measuring container 11 is disposed at the bottom thereof, and the liquid level sensor 13 is disposed at the top of the inner cavity of the measuring container 11;

[0029] The liquid level sensor 13 and the weighing device 16 are both electrically connected to the control panel 14;

[0030] The metering container 11 is connected to the water inlet pipe 211 and the water outlet pipe 212 through a flange, and an electric butterfly valve 22 is also provided between the metering container 11 and the water inlet pipe 211 and the water outlet pipe 212;

[0031] The electric butterfly valve 22 is electrically connected to the control panel 14 .

[0032] The metering container 11 is a cube or a cylinder.

[0033] The support plate 17 is disposed in the box body 10 via a bracket 18 .

[0034] The metering container 11 is provided with an exhaust pipe 15 , and the exhaust pipe 15 passes through the outer shell of the box body 10 .

[0035] The weighing device 16 is a hydraulic gauge.

[0036] The flange is sealed by bolts.

[0037] Each of the metering containers 11 is equipped with two electric butterfly valves 22 , one electric butterfly valve 22 is arranged between the flange and the water inlet pipe 211 , and the other electric butterfly valve 22 is arranged between the water outlet end of the metering container 11 and the flange.

[0038] The control panel 14 controls the opening mode of the electric butterfly valve 22 to achieve the purpose of controlling the volume of the liquid inside the measuring container 11; the weighing device 16 is located at the bottom of the measuring container 11, and the density of the liquid in the measuring container 11 can be monitored by the weighing device 16. When the liquid quality is unqualified, the weighing device 16 sends a signal and the control panel 14 sends an alarm; the volume of the liquid inside the measuring container 11 is controlled so that the volume of the liquid in the volume is fixed and accurate, thereby improving the accuracy;

[0039] The water inlet pipe 211 and the water outlet pipe 212 are connected to the measuring container 11 through flanges, and the flanges are fixed by bolts. The measuring container 11 can be designed into different specifications to adapt to different liquid conditions;

[0040] An exhaust pipe 15 is installed on the top of the measuring container 11, and the exhaust pipe 15 extends outside the device to make the internal and external air pressures the same, thereby reducing safety risks;

[0041] Combination Figure 1 As shown, when the liquid flows into the water inlet pipe 211, the electric butterfly valve 22 at the water inlet end of the metering container 11 is opened, and the electric butterfly valve 22 at the water outlet end is closed at the same time, so that the liquid is stored in the liquid storage mechanism I121 and the liquid storage mechanism II122. When the water level touches the liquid level sensor, the electric butterfly valve 22 at the water inlet end of the metering container 11 is closed through the control panel 14, and the electric butterfly valve 22 at the water outlet end of the metering container 11 is opened. This operation is repeated so that the liquid is intermittent. By counting the number of times the control panel 14 is opened and closed, the flow rate of the liquid passing through is calculated.

[0042] When the liquid in the measuring container 11 is not full and does not contact the liquid level sensor 13, the liquid is weighed by the weighing device 16 to obtain the volume of the liquid and complete the statistics.

[0043] Combination Figure 2 As shown, when the flow rate in and out of the water inlet pipe 211 is too fast and the volume of the metering container 11 does not meet the internal flow rate, the metering container 11 of different containers is adjusted by removing the flange to meet the flow rate in the water inlet pipe 211, so that water can continuously flow out from the water outlet pipe 212 and the liquid flow rate is calculated.

[0044] The measuring container 11 has the same volume when in different shapes. When the flow rate in and out of the water inlet pipe 211 is too fast and the volume of the measuring container 11 does not meet the internal flow rate, the measuring container 11 of different shapes is adjusted by removing the flange to meet the flow rate in the water inlet pipe 211, so that water can continuously flow out from the water outlet pipe 212 and the liquid flow rate can be calculated.
