However, cavitation occurs when the oil is shaken and bubbles in the process of transporting oil through the tank lorry, and when the oil is pumped from the tank into the underground storage tank, cavitation (when the liquid is flowing, The air is separated from the vapor in the liquid to generate air bubbles and cavities are formed. As a result, a large amount of air bubbles are generated due to the presence of the air bubbles in the transfer oil, which is difficult to measure in the process of being supplied to the storage tank of the gas station There was a problem following.

In order to solve such a conventional problem, Patent Document 1 discloses an air conditioner comprising an air reservoir connected to a oil supply unit and the oil supply unit to retain air by a difference in weight between air and a liquid, a turbine connected to a lower side of the air reservoir, A temperature sensor for detecting a temperature signal of the liquid, which is incorporated into or near the flowmeter unit and the turbine flowmeter unit, and a gas-liquid separator connected to the upper portion of the air reservoir for bypassing the air- And a computer means for receiving the temperature signal and the rotation signal to calculate a flow rate and controlling a valve and the like, thereby providing a liquid metering apparatus capable of measuring the flow rate of the liquid in real time.

However, in the above-mentioned Patent Document 1, the air can be discharged by the 'A' air reservoir to the main piping, but the flow of the oil by the 'A' piping causes vortex, , It is difficult to calculate the accurate flow rate due to the generation of the bubbles due to the vortex, and the facility cost is somewhat high due to complicated equipment.

The foam breaker 250 is partitioned along the periphery of the cylindrical body 270 so as to be spaced apart from the cylindrical body 270 by a predetermined distance so that the inner space of the case 210 is divided .

At this time, the partition wall constituting the foam breaker 250 may be integrally formed at the lower part of the protector 270. In this case, the foam breaker 250 may be installed on an inner part of the protector 270, And a joining member 280 'for supporting the swash plate 240 and the foam breaker 250 to be supported.

This is because it allows the pressure of the collected liquid to flow more firmly to the bottom.

The bubble discharging pipe 260 penetrates the center of the case 210 and is connected to the gas-liquid separator 300 provided at the upper part of the case 210 to discharge the gas generated from the bubble. Can be performed.

The gas-liquid separator 300 discharges the gas generated by the bubbles of the liquid discharged by the bubble removing unit 200, The liquid to be wasted can be minimized.

The cylindrical body 270 covers the lower end of the case 210 so as to adjust the amount of the liquid flowing into the inlet hole 211 connected to the supply pipe 100, A plurality of punched holes 271 are formed in the lower portion of the case 210 so as to allow the liquid flowing down the wall of the case 210 along the swash plate 240 to flow into the supply pipe 100 without generating vortex Can be formed.

According to an embodiment of the present invention, the bubble discharging pipe 260 may penetrate the center of the case 210 and penetrate the inside of the cylindrical case 270, And a hole for discharging the gas generated while bubbles are removed from the outside of the cylindrical body 270 may be formed on a wall surface of the cylindrical body 270 connected to the bubble discharge pipe 260 have.

The bubbled liquid flows into the cylindrical body 270 through the ridge 271 formed in the cylindrical body 270 and is supplied to the storage tank T through the supply pipe 100 And the gas generated from the bubbles removed from the liquid can be discharged to the gas-liquid separator 300, which is spaced apart from the upper portion of the foam eliminator 200 through the bubble discharge pipe 260.

The buoy 272 can be moved up and down along the bubble discharging pipe 260 passing through the inside of the cylindrical body 270 and the height restricting means 273 is coupled to restrict the vertical moving height .

That is, the buoy 272 provides up and down buoyancy in accordance with the amount of the introduced liquid so that the bubble discharging pipe 260 can be moved up and down, so that bubbles can be smoothly discharged corresponding to the amount of liquid, The height of the upper tank 270 is limited by the height restricting means 273 so that a certain level of liquid is allowed to exist in the cylindrical tank 270 and the liquid is supplied to the storage tank T To be able to do so.

According to an embodiment of the present invention, the gas-liquid separator 300 may include a separator body 310, a perforated plate 320, a discharge pipe 330, and a recovery pipe 340 as shown in FIG. And may be connected to the upper part of the bubble removing unit 200 by the bubble discharge pipe 260 passing through the center of the bubble removing unit 200.

Here, the separator body 310 refers to the external appearance of the gas-liquid separator 300 and may be connected to the bubble discharge pipe 260 so that the bubbles discharged from the bubble rejection unit 200 may be introduced into the interior.

The vapor, which is a gas generated from the oil, is not discharged directly to the outside because of a high risk of fire or explosion, and can be safely treated through a vapor treatment apparatus generally provided in a storage tank (T) for storing oil.

Also, since the small amount of gas generated in the gas-liquid separator 300 does not affect the stock amount of the oil already supplied from the measuring unit 400, 400) and the storage tank (T).
