本考案は、流路管内を流れている液体中に混し
ている空気を前記液体から分離するため気液分離
装置の改良に関する。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an improvement in a gas-liquid separation device for separating air mixed in a liquid flowing in a flow path pipe from the liquid.
従来の技術
流量計により液体計測を行う場合、被計測液体

により流体の計量を正確に行うようにしている。BACKGROUND ART When measuring a liquid using a flowmeter, if a gas is mixed into the liquid to be measured, no matter how accurate the flowmeter is, accurate measurement cannot be performed. In such cases, by using an air separator, the gas in the liquid can be removed, and after the gas has been removed, the liquid can be measured by passing it through a flowmeter to accurately measure the fluid. That's what I do.

し、弁機構6が閉となる。 FIG. 5 is a sectional view for explaining an example of a conventional gas-liquid separation device. In the figure, 1 has a liquid inlet 2 and an outlet 3 at the bottom, and an air reservoir 4 at the top. In the liquid separation tank, the liquid containing air bubbles that flows into the tank 1 from the inlet 2 is separated from the air bubbles in the tank 1 and then flows out through the outlet 3.
The gas separated in the tank 1 accumulates in the air reservoir 4, and the liquid level gradually decreases. A float 5 is floating on the liquid level, and a valve mechanism 6 is provided above the float 5. When the float lowers as described above and reaches a predetermined position, the valve mechanism 6 opens. , the air in the air reservoir 4 is discharged from the exhaust port 31.
released to the outside. When the air in the air reservoir 4 is released to the outside, the pressure in the air reservoir 4 decreases, the liquid level rises, the float rises, and the valve mechanism 6 closes.

す。 FIG. 6 is a cross-sectional view taken along the line A-A in FIG.
An outer cylinder 20 is provided on the outside of the inner cylinder 10 and moves up and down in sliding contact with the inner cylinder 10, and an opening 11 is provided in the side wall of the inner cylinder 10. The outer cylinder 20 is connected to the float 5 via a pin 30, and while the air in the air reservoir 4 is low, the float 5 is in the state shown in the figure, and therefore the opening 11 of the inner cylinder 10 is connected to the outer cylinder 20. The air inside the air reservoir 4 is discharged to the outside in small amounts through the minute gap 32. After the air is completely exhausted, the liquid tries to be expelled, but since its viscosity is much higher than that of gas, the leakage is extremely small. However, when the air mixed in the liquid is separated from the liquid as described above and the amount of air in the air reservoir 4 increases, the air volume in the air reservoir increases and the liquid level decreases. Then, the float 5 lowers and finally the outer cylinder 2
0 falls below the opening 11 of the inner cylinder 10, the air reservoir 4 and the outside communicate through the opening 11, and the air in the air reservoir 4 is discharged to the outside.
When the air in the air reservoir 4 is released to the outside, the liquid level in the tank 1 rises again, causing the outer cylinder 20 to rise to the inner cylinder 10.
The opening 11 is closed, and the same operation is repeated.

ストの増大をまねき、又、LPGなどのような低
比重液などの場合、浮力が得られず、大きな問題
となる。 Therefore, in the above-mentioned conventional gas-liquid separator,
Due to the pressure difference between the pressure inside the tank 1 and the pressure outside the tank 1, that is, the pressure in the inner cylinder 10, the outer cylinder 20 is attracted to the side surface of the inner cylinder 10 even when the communication port 11 is in a symmetrical position. For example, as shown in Fig. 6, the outer cylinder is eccentric and comes into contact with the inner cylinder, and due to frictional force, a large force is required to raise the outer cylinder. Therefore, a float with large buoyancy must be used. In addition, a large force is required when descending, which necessitates the use of a heavy float, which requires contradictory performance from the float. This leads to an increase in manufacturing costs due to the increase in size, and in the case of low specific gravity liquids such as LPG, buoyancy cannot be obtained, which poses a big problem.

It operates as described with respect to FIGS. 5 and 6. Therefore, in the present invention, a groove 21 is provided on the inner circumferential surface of the outer cylinder 20 so as to cover the opening 11, so that the pressure balance between the inner cylinder 10 and the outer cylinder 20 is completely maintained. It is maintained substantially uniform over the circumference, and the frictional force at the contact surface between the inner cylinder 10 and the outer cylinder 20 can be reduced without receiving differential pressure when the outer cylinder 20 is eccentric with respect to the inner cylinder 10. The float 5 can move up and down smoothly.
