It is connected.
In the present invention, measurement inner cavity 2 is equipped in the shell 1.The measurement inner cavity 2 is one and is arranged described
Hollow cavity inside shell 1.The entrance 3 is communicated with the measurement inner cavity 2.Gas-liquid mixture from the input channel
(it is, crude oil from oil well) is entered inside the measurement inner cavity 2 by the entrance 3.
Spool 6 is equipped in the measurement inner cavity 2.The upper end of the spool 6 is equipped with electromagnetic coil 7.The electromagnetic coil 7 with
Control circuit is connected.The spool 6 is equipped with lower valve 8 and upper valve 9.Wherein, the lower valve 8 is for controlling the measurement
Whether the bottom of inner cavity 2 communicates with the inside of the shell 1.The top that the upper valve 9 is used to control the measurement inner cavity 2 is
The no inside with the shell 1 communicates.
Specifically, the positive energization of the electromagnetic coil 7 is controlled by the control circuit, moves downward the spool 6,
To make the lower valve 8 close and the upper valve 9 is connected.In this way, from the input channel gas-liquid mixture (
Be exactly crude oil) enter the measurement inner cavity 2 after, the survey is discharged by the upper valve 9 in the gas in the gas-liquid mixture
Inner cavity 2 is measured, liquid L is stayed in inside the measurement inner cavity 2.As shown in Figure 2.
The electromagnetic coil 7 is controlled by the control circuit to be reversely powered, and moves upwards the spool 6, to make
The lower valve 8 is connected and closes the upper valve 9.In this way, it is described to pass through the liquid L entered in the measurement inner cavity 2
Lower valve 8 is discharged.Also, since the upper valve 9 is to close, gas G can not be discharged, so that it is described to remain in gas G
It measures in inner cavity 2.As shown in Figure 3.
