Description

Description: TECHNICAL FIELD The present invention relates to a water remover provided at a lower end of a suction pipe of an oil supply device installed in a gas station such as a gas station.

[Prior Art] As is well known, since water and drainage of water vapor are accumulated at the bottom of an underground tank at a gas station, the water is drained if a predetermined amount or more is accumulated. Therefore, a water remover having an opening generally facing upward from the bottom of the tank is attached to the lower end of the suction pipe so as not to suck them when refueling from the fueling machine.

[Problems to be Solved by the Invention] In the above-mentioned water remover, a foot portion for determining a constant height of the opening is vertically provided.

By the way, the amount of water and drain accumulated depends on the environment of the gas station, that is, the temperature and humidity, and the height of accumulation depends on the shape of the underground tank. Therefore, if the height of the opening is constant, the dead stock becomes large in an underground tank where the height of water and drain is low and the horizontal area is large.Therefore, cut the lower part of the foot to lower the opening as much as possible. It is necessary to provide. If the height of water or drain is high in a tank having a small horizontal area, the water and drain will be sucked in if the opening is too low. Therefore, the foot should be used without cutting in order to raise the opening.

This foot is cut by measuring the length from the opening to the cutting position using a 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 measure or the like across the large diameter portion and the small diameter portion.

An object of the present invention is to provide a water remover that facilitates length determination when cutting a foot.

[Means for Solving the Problems] According to the present invention, in the water remover provided at the lower end of the suction pipe of the oil supply device, the main body attached to the suction pipe and the foot suspended from the bottom of the main body. A plurality of inflow ports are opened in the side surface of the main body, a drainage hole is bored in the bottom part, and a scale indicating the position from the inflow port is provided in the foot part. .

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

Further, 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.

Embodiments Embodiments of the present invention will be described below with reference to the drawings.

In FIG. 1, a refueling machine 1 installed on the site A of a gas station
Is provided with a suction pipe 2, and the suction pipe 2 has an opening 3a.
It is inserted in the underground tank 3 from. The wick 2
The water remover 10 is provided at the lower end of the water remover 10, and the foot 16 hung from the bottom of the water remover 10 contacts the bottom of the underground tank 3.
The height of the after-mentioned inflow port 13 which is an opening is positioned.
In the figure, reference numeral 4 is a measuring port, 5 is a filler port of the filler pipe 6,
Reference numeral 7 is a ventilation pipe provided with a ventilation port 8 at the upper end.

In FIG. 2, the water remover 10 is composed of a main body 11 that is screwed into the suction pipe 2, and a foot portion 16 that is vertically provided from the bottom of the main body 11.

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

The foot portion 16 has a columnar shape and is integrally formed with the bottom portion 14, and is reinforced by ribs 17. On the foot portion 16, two step portion scales 18 and 19 forming a scale for cutting are formed.

Therefore, due to the lower end 20 of the foot 16 and the step marks 19 and 18, the heights H1, H2, H3 from the bottom of the underground tank 3 at the lower edge of the inlet 13 are, for example, 150 mm, 120 mm, 100.
mm can be decided.

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

EFFECTS OF THE INVENTION Since the present invention is configured as described above, the height of the inflow port 13 from the bottom of the underground tank 3 can be directly measured using the step scales 18, 19 or without using a measure or the like. It can be easily determined on the scale scale 21.

Further, since the inflow port 13 is provided on the side surface of the main body 11, the outer diameter of the main body 11 is larger than the outer diameter D1 of the suction pipe 2 as compared with the conventional water removing device in which the inflow port is provided on the upper surface of the main body. D2 can be reduced. Therefore, even if the inner diameter of the opening 3a of the underground tank 3 is small, the thick suction pipe 2 can be provided, and the flow path resistance of the suction pipe 2 can be reduced accordingly.
