The present invention relates to an oil tank flow rate measuring device for the use of fake gasoline determination, and more particularly, a flow rate measuring device equipped with a measurer and a fake gasoline determination member is inserted into an oil tank of a gas station to easily measure the flow rate inside and at the same time. The present invention relates to a flow rate measuring device capable of discriminating gasoline.

Generally, oil tanks at gas stations are installed underground, and the oil tanks are large enough to store very large volumes of oil.

According to FIG. 1, a very long rectangular bar 2 is used to measure the amount of oil S in the oil tank 1, and the depth of the oil tank 1 is at least 5 m to 10 m deep. Square bars (2) vary and are slightly longer than the depth of the oil tank.

Therefore, the conventional square bar 2 is soaked so as to stand inside the oil tank (1).

Next, to measure the flow rate, the square bar (2) is pulled out of the oil tank (1), and the flow rate is measured by visually identifying the upper scale of the oil on the surface of the square bar (2). This is the same as using the long measuring bar to visually measure the oil on it.

However, when measuring the oil in the gas station oil tank (1), it is difficult to measure with the naked eye at night, and in the case of gasoline, it is slightly yellowish, so it is easy to identify, but it is easily volatilized because of its high volatility. There was a problem that could not be measured accurately because it was not well identified, which caused trouble to measure again and again for accurate measurement.

On the other hand, bad fuel (petrol) refers to a product manufactured by mixing toluene and methane with a solvent, a normal fuel produced by an oil refining company, and when such a bad fuel is used in a vehicle, the fuel is not combusted normally and the output is lowered. Will damage.

In addition, the fuel economy of the engine is greatly reduced and the performance of the vehicle is shortened by adversely affecting the engine performance, and the fuel is not completely burned while the vehicle is running, and toxic gases harmful to the human body and the environment are leaked into the air without defense. It threatens people's health and natural environment. The production and sales of such poor fuels (petrol) have been further driven by inflation and rising prices.

In order to solve the above problems, recently, equipment for determining whether fuel is bad using specific gravity and vapor pressure, which are inherent in fuel (petrol), has been used as a means of continuously controlling gas stations in police or municipalities.

However, these equipments are expensive and there is a problem that excessive maintenance costs are spent in the event of a failure, and the problem has existed because it takes a lot of time to determine whether the fuel is defective.

Therefore, the present invention can easily incorporate the flow rate measuring device equipped with a hose and the measuring device in the gas station oil tank to solve the above problems, the oil flowed into the hose more easily with the naked eye to measure the flow rate, even at night It is an object of the present invention to provide a flow measurement device that facilitates flow measurement.

The jaw 211a is formed, and the upper end portion is formed with a first fitting portion 213 protruding to a certain height so that the hose 300 to be described later is coupled, and the foreign matter E of the oil tank bottom is oil (S) at the lower end portion. The second fitting portion 214 is formed to prevent the inflow, such that the support member 260 is fitted to the second fitting portion 214 so that the foreign matter E is almost in contact with the bottom of the oil tank. To prevent the inflow to

Here, since the support member 260 is in contact with the bottom of the oil tank in order to prevent the foreign substance (E) of the bottom of the oil tank into the first inlet 211, only a small amount of oil (S) is introduced, An amount of oil larger than the amount of oil S flowing into the first inlet 211 is formed on the outer circumferential surface of the body portion 210 and is introduced through the second inlet 212 connected to the first inlet 211. . In addition, by forming a plurality of second inlet 212 on the outer circumferential surface of the body portion 210 so that the oil filled in the oil tank can be moved to the hose 300 more quickly to shorten the measurement time Of course.

The oil 230 introduced between the upper end of the first fitting portion 212 and the bolt 230 is inserted into the bolt 230 by the O-ring 240 made of rubber material, and the first and second inlets ( 211 and 212 to prevent leakage.

Here, the nut 250 mounted on the bolt 230 is mounted to prevent the spring 220 caught by the body portion 210 from falling out, and is vibrated by the elastic force of the spring 220. It is preferable that a pair of nuts 250 are mounted on the bolts 230 to prevent the nuts 250 from being loosened.

As shown in FIG. 7, the flow rate measuring device 100 measures the oil introduced through the oil inlet 200 and checks the flow rate in the oil tank and determines whether the oil S is fake. The configuration of the hose 300 is installed so that the oil (S) introduced into the first fitting portion 213 to the upper side by the height of the flow rate filled in the oil tank, and the hose 300 is One side is opened to be fitted and fixed, the support portion 410 of the circular groove is formed in the longitudinal direction, the lower end is composed of a frame 400 is fixed to the upper end of the oil inlet 200 with an adhesive.

As illustrated in FIG. 8, the frame 400 has guide grooves 420 formed up and down so as to face both sides, and the guide groove 420 is fitted with a measurer 500 and one guide groove 420. The fake gasoline determination member 600 is inserted into the gasoline to determine the fake gasoline, and is caught by the clamping portions 421 formed at both ends of the guide groove 420 to measure the measuring member 500 and the fake gasoline determination member 600. Is firmly fixed. In addition, the frame 400 is made to the length of more than 3m, which is because the depth of the oil tank of the gas station is approximately 3m, but in the case of a large capacity oil tank can be more than 3m depth of the connector 700 will be described later ) And the connecting tube 800 and the frame 400 are sequentially coupled to extend its length.

At this time, the frame 400 is equipped with the measuring device 500 and the fake gasoline determination member 600, the lower end thereof is bonded to the upper surface 215 of the oil inlet 200, the measuring device 500 The fake gasoline determination member 600 is prevented from falling downward from the guide groove 420 of the frame 400.

Here, the measurer 500 is a tape measure made of a generally used metal, but is not limited thereto, and any measurer may be used as long as the scale is displayed.

As shown in FIG. 9, the fake gasoline determination member 600 is made of polyvinyl chloride (PVC) to examine the toluene component contained in the fake gasoline, such that the PVC is in contact with toluene. If the toluene penetrates into the PVC and the polymer chain is broken, fine cracks are densely generated on the surface, thereby causing whitening, which is shown in Table 1 below. As it increases, the color becomes gradually whiter and darker, thereby predicting the amount of toluene contained in the gasoline, thereby determining whether the gasoline is fake.

Here, the fake gasoline containing toluene is composed of 45wt% of solvent (Solvent), 50wt% of toluene and 5wt% of methane (methane), the content of the fake gasoline shown in Table 1, that is, the weight ratio 10 %, 30%, 50%, 70%, 100% is toluene contained in the weight ratio of 5%, 15%, 25%, 35%, 50%, respectively.

Table 2 below shows the weight change of toluene contained in gasoline and the color change of the fake gasoline discriminating member according to the time elapsed. As the weight ratio of toluene increases in the gasoline, the rigid PVC is made over time. In 610, the whitening phenomenon is continuously increased. In contrast, in the soft PVC (620), when the toluene component is lowered, gasoline infiltrates into the tissue over time, causing sulfidation to increase, thereby inversely establishing each other. You can see that.

Here, the material of the fake gasoline determination member is not limited to PVC, and any synthetic resin may be used as long as it is a synthetic resin causing whitening due to cracks caused by contact with toluene.

In addition, the upper end of the frame 400, as shown in Figure 10 is formed in the frame 400, the projection 710 formed in the connector 700 for the flow measurement and the determination of the fake gasoline even in a large oil tank The fixing part is inserted into the support part 410, and the connector 700 and the frame 400 are sequentially connected after the connector tube 800 is fixed to the upper part of the connector 700, thereby allowing the flow rate measuring device 100 to be fixed. Will be able to extend the length of.

Referring to the operating state of the flow measurement device is configured as follows.

When pressed in the direction of the arrow, the bolt 230 is pushed upward, the oil (S) filled in the oil tank is formed in the oil inlet 200, the first inlet 211 and the second inlet 212 Inflow through the oil, the oil (S) is filled to the same height as the flow rate filled in the oil tank in the hose 300 connected to the oil inlet 200.

Subsequently, when the flow rate measuring device 100 is pulled up after a predetermined time, the bolt 230 is moved downward by the elastic force of the spring 220 which is reduced in the oil inlet 200, and the bolt is moved downward. The O-ring 240 mounted on the 230 blocks the upper end of the first inlet 211 to prevent the oil S introduced into the hose 300 from leaking back to the oil inlet 200, so that the correct flow rate Can be measured.

Subsequently, the flow measuring device 100 which is vertically drawn out of the oil tank is made to coincide with the scale of the measuring device 500 mounted on the frame 400 and the surface of the oil S filled in the hose 300. By visually checking the value, it is possible to measure the flow rate of oil filled in the oil tank. At this time, the fake gasoline determination member 600 mounted on the frame 400 is in contact with the oil for a predetermined time in the process of being inserted into the oil tank, as shown in Table 1 according to the whitening phenomenon according to the amount of toluene contained in the oil By comparing and analyzing the change in the color change reference table (see Table 1) of the fake gasoline determination member 600, it is possible to determine the defective gasoline.

In this way, with respect to the flow rate measuring device of the present invention, all the various design changes of the respective components within the scope of the present invention are considered to be included in the scope of the technical idea of the present invention.

As described above, the flow measuring device according to the present invention easily incorporates a flow measuring device equipped with a hose and a measurer into a gas station oil tank to measure the flow rate of oil introduced into the hose more easily with the naked eye through a measuring instrument, and measures the flow rate even at night. This has the effect of being easy.

In addition, the flow measuring device is simple in configuration, and there is almost no possibility of failure or corrosion, so it can be used semi-permanently and requires no maintenance. Since the fake gasoline discriminating member is a plate formed of PVC, it can be replaced at a low price. By visually checking the whitening phenomenon of fake gasoline discrimination member by toluene component included in gasoline, it is easy to determine whether the oil is fake.If it is determined as fake gasoline by whitening phenomenon, it can be used again immediately after replacing the discriminating gasoline. It works.
