Description

Technical Field

[0001] The utility model relates to the field of oil and gas acquisition and detection, and particularly relates to a liquid flow measurement mechanism and an analysis device. Background Art

[0002] In oil and gas fields, a metal cylindrical flow cell is used to analyze the actual situation of liquid media, so as to ensure the safety of oil and gas production and transportation.

[0003] However, the currently used metal cylindrical flow cell is integrally sealed. During the analysis operation, operators cannot determine the liquid level in the flow measurement cell and cannot judge whether the measurement probe is immersed in the liquid to be measured, resulting in distorted measurement data and prolonged measurement time. Moreover, since the metal cylindrical flow cell is directly connected to the process pipeline, the metal cylindrical flow cell is greatly affected by the flow rate of the liquid medium in the process pipeline. When the flow rate is too large, the liquid medium will overflow from the cover plate. When the flow rate is too small, the liquid medium in the metal cylindrical flow cell lags behind the liquid medium in the process pipeline, and even the liquid medium in the metal cylindrical flow cell dries up, resulting in the exposure of the measurement probe, causing inaccurate measurement results of the measurement probe. Content of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiency that it is difficult to control the liquid level in the metal cylindrical flow cell in the prior art, and provide a liquid flow measurement mechanism and an analysis device.

[0005] In the first aspect, the utility model provides a liquid flow measurement mechanism, including

[0006] A device body, the device body is provided with a measurement chamber, a liquid inlet and a liquid outlet, and the liquid inlet and the liquid outlet are respectively communicated with the measurement chamber;

[0007] A flow rate regulating device, the liquid inlet is connected to a liquid inlet pipeline, the liquid outlet is connected to a liquid outlet pipeline, and the flow rate regulating device is arranged on the liquid inlet pipeline and / or the liquid outlet pipeline;

[0010] A liquid flow measurement mechanism of the present utility model. The liquid medium flows in the measurement cavity through the liquid inlet and the liquid outlet. The flow rate adjustment device can control the flow rate of the liquid medium entering or discharging from the measurement cavity, thereby controlling the liquid level height in the measurement cavity and avoiding the influence of the liquid medium level in the measurement cavity by the liquid medium flow rate in the process pipeline. By connecting both ends of the liquid level observation pipeline to the measurement cavity, a communicating vessel is formed between the liquid level observation tube and the measurement cavity. By observing the liquid level height in the liquid level observation tube, the liquid level height in the measurement cavity can be judged, enabling the operator to adjust the flow rate adjustment device according to the observed liquid level height, controlling the contact between the liquid medium in the measurement cavity and the measurement probe, reducing the measurement time, and improving the measurement efficiency. The highest point of the liquid level observation tube is higher than the lowest point of the measurement probe, ensuring that the operator can control the liquid level height to contact the measurement probe.

By arranging the liquid inlet at the bottom of the device body, the occurrence of liquid dryness in the measurement cavity is avoided.

[0023] Preferably, the flow rate regulating device includes a first valve and a second valve. The first valve is arranged on the liquid inlet pipe, and the second valve is arranged on the liquid discharge pipe.

[0024] By jointly controlling the liquid level height in the measurement cavity by the first valve and the second valve, the liquid level height can be controlled more accurately, which is convenient for operation and ensures that the measurement probe can always be in contact with the liquid medium during measurement.

[0025] In a second aspect, the present invention provides an analysis device, which includes a data processing device and the above-mentioned liquid circulation measurement mechanism, and the data processing device is connected to the measurement probe.

An inlet 12 and an outlet 13 are opened on the device body 1, so that the inlet 12 and the outlet 13 are respectively communicated with the measurement chamber 11; the liquid medium flows in the measurement chamber 11 through the inlet 12 and the outlet 13; an inlet pipe 14 is connected to the inlet 12, a drain pipe 15 is connected to the outlet 13, and a flow rate regulating device 2 is respectively provided on the inlet pipe 14 and the drain pipe 15. The flow rate of the liquid medium flowing in and out of the measurement chamber 11 is regulated by the flow rate regulating device 2, so that the liquid level height in the measurement chamber 11 can always be maintained at an appropriate position; by providing a liquid level observation tube 3 on the device body 1, both ends of the liquid level observation tube 3 are respectively communicated with the measurement chamber 11 to form a communicating vessel, and the liquid level height in the measurement chamber 11 can be judged from the liquid level observation tube 3 through the communicating vessel principle; the measurement probe 4 extends into the measurement chamber 11 and is fixed on the device body 1, so that the highest point of the liquid level observation tube 3 is higher than the lowest point of the measurement probe 4.

[0055] The liquid medium flows in the measurement chamber 11 through the liquid inlet 12 and the liquid outlet 13. The flow rate regulating device 2 can control the flow rate of the liquid medium entering or discharging from the measurement chamber 11, thereby controlling the liquid level height in the measurement chamber 11 and avoiding the influence of the liquid medium flow rate in the process pipeline on the liquid level of the liquid medium in the measurement chamber 11. By connecting both ends of the liquid level observation pipe 3 to the measurement chamber 11, a communicating vessel is formed between the liquid level observation pipe 3 and the measurement chamber 11. The liquid level height in the measurement chamber 11 is judged by observing the liquid level height in the liquid level observation pipe 3, enabling the operator to adjust the flow rate regulating device 2 according to the observed liquid level height, controlling the contact between the liquid medium in the measurement chamber 11 and the measurement probe 4, reducing the measurement time, and improving the measurement efficiency.

The vertically arranged transparent pipe section 31 has a larger liquid level visual range, is easier to reflect the difference between the current liquid level and the established liquid level, and is more convenient for the operator to adjust. A number of scales are set on the transparent pipe section 31, and the liquid level height is accurately judged by reading the scales.

After the liquid medium enters the measurement chamber 11, it accumulates in the measurement chamber 11 until the liquid level height of the liquid medium reaches the liquid outlet 13 and is discharged from the measurement chamber 11 through the liquid outlet 13, thereby ensuring that the liquid medium is measured by the measurement probe 4 before being discharged from the measurement chamber 11, and leaving a certain space at the top of the measurement chamber 11 to avoid the overflow of the liquid medium when the flow rate is too large.

[0064] In one or more embodiments, the flow regulating device 2 is only composed of the second valve, and the flow rate of the liquid medium discharged through the liquid discharge pipeline 15 is controlled by the second valve, so as to realize the control of the liquid level of the measurement chamber 11.
