Abstract

PURPOSE:To facilitate the determination of length at the time of cutting a leg portion in a water remover provided on the bottom end of a suction pipe of an oil feeding device installed on a service station, etc., by providing a scale mark for cutting on the leg portion which serves for determining a defined height position of the opening thereof. CONSTITUTION:A suction pipe 2 is provided on an oil feeding device 1 provided in the ground A of a service station. This suction pipe 2 is inserted into an underground tank 3 from an opening portion 3a and a water remover 10 is installed on the bottom end thereof. A leg portion 16 is extended downward from the bottom portion of the water remover 10 and this leg portion 16 is brought into contact with the bottom portion of the underground tank 3, to determine the height position of a flow-in port 13, or an opening. In this case, two step-portion scale marks 18, 19 as scale marks for cutting are formed on the leg portion 16. Due to the bottom end portion 20 and the step-portion scale marks 19, 18 of the leg portion 16, the height H1-H3 of the flow-in port 13 from the bottom portion of the underground tank 3 can be determined as, e.g., 150mm, 120mm, 100mm.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a water remover installed at the lower end of a suction pipe of a refueling device installed at a refueling station such as a gas station.

[Prior Art] As is well known, at the bottom of an underground tank at a gas station, water or drainage containing dew vapor accumulates, and if a predetermined amount or more has accumulated, the tank is drained. Therefore, in order to prevent these from being sucked in when refueling from a refueling machine, a water remover, which normally has an upwardly facing opening, is attached to the lower end of the suction pipe at a certain height from the bottom of the tank.

[Problems to be Solved by the Invention] The water remover described above is provided with a vertical leg portion that determines a certain height of the opening.

Incidentally, the amount of water or drain that accumulates varies depending on the environment of the gas station, that is, the temperature and humidity, and the height of the accumulation varies depending on the shape of the underground tank. Therefore, if the height of the opening is constant, the dead stock will be large in an underground tank with a large horizontal area at a low height where water and drains accumulate, so the lower part of the foot should be cut off to make the opening as low as possible. It is necessary to provide Also, if the tank has a small horizontal area and the water and drain are high, if the opening is too low, water and drain will be sucked in, so use the tank without cutting off the legs to make the opening higher.

The leg is cut by measuring the length from the opening to the cutting position using a tape measure or the like. However, since the suction pipe connecting portion of the main body having the opening has a large diameter and the foot portion has a small diameter, it is troublesome to measure with a tape measure or the like across the large diameter portion and the small diameter portion.

SUMMARY OF THE INVENTION An object of the present invention is to provide a water remover that makes it easy to shorten the length of a leg when it is cut.

[Means to solve problems] According to the present invention, a cutting scale is attached to the foot.

It is preferable that the cutting scale is formed by a step, but it may also be formed by engraving a scale mark or by engraving a number on the step.

Moreover, it is preferable that the opening is formed in the side surface of the main body connected to the suction pipe.

[Function] In the water remover configured as described above, when cutting the foot, the length can be easily determined using the cutting scale without using a measuring tape or the like.

Moreover, since the opening is provided on the side surface, the outer diameter of the main body connected to the suction pipe can be made as small as possible with respect to the outer diameter of the suction pipe.

[Example code] The present invention will be described in detail below with reference to the drawings.

In Figure 1, the refueling station 1f installed at the site A of the refueling station
A suction pipe 2 is provided in the il, and the suction pipe 2 is inserted into the underground tank 3 through an opening 3a. A water remover 10 is provided at the lower end of the suction pipe 2, and a foot portion 16 hanging down from the bottom of the water remover 10 is in contact with the bottom of the underground tank 3, and the height of the inlet 13, which is an opening, is positioning. In addition, the reference numeral 4 in the figure is a measuring port, 5 is an oil supply port of the oil supply pipe 6, and 7 is a ventilation pipe with a ventilation port 8 provided at its upper end.

In FIG. 2, the water remover 10 consists of a main body 11 which is screwed onto the suction pipe 2, and a leg part 16 which is vertically disposed from the bottom of the main body 11.

The main body 11 consists of a flange-shaped upper part 12 connected to the suction pipe 2, and a substantially hemispherical bottom part 14 fitted into the upper part 12. A plurality of (four in the illustrated example) inlet ports 13 are opened in the side surface of the upper portion 12, and a drain hole 15 is bored in the bottom surface of the bottom portion 14.

The foot portion 16 has a columnar shape, is formed integrally with the bottom portion 14, and is reinforced with ribs 17. Two stepped graduations 18.1 forming cutting graduations are formed on the foot portion 16.

Therefore, the heights Hl, H2, H3 of the lower edge of the inlet 13 from the bottom of the underground tank 3 are determined by the lower end 20 of the foot part 16 and the step scale 19.18, for example, 150 mm, 120 mm, 10 mm.
It is now possible to determine 0QII11.

FIG. 3 shows another embodiment of the present invention, in which a scale 21 is engraved on the foot 16, and the other parts are formed in the same manner as in FIG. Therefore, the height of the lower edge of the inlet 13 from the bottom of the underground tank 3 can be precisely determined by the scale 21.

[Effects of the Invention] Since the present invention is configured as described above, the height of the inlet 13 from the bottom of the underground tank 3 can be measured directly on the step scale 18, 19 or 18 without using a measuring tape or the like. This can be easily determined using the scale 21.

In addition, since the inlet 13 is provided on the side surface of the main body 11, the outer diameter of the main body 11 is D2 can be made small. Therefore, even if the inner diameter of the opening 3a of the underground tank 3 is small, a thick suction pipe 2 can be provided, and the flow path resistance of the suction pipe 2 can be reduced accordingly.
