Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a water tank used, for example, in a water supply pressurizing device, and particularly relates to an improvement in the closing structure of an inspection opening.

Tap water pressurization devices are often used, which store tap water in a water tank, pressurize it with a pump, and then supply the water to where it is needed, so that a predetermined water pressure can always be obtained.

A conventional device of this type is shown in FIG.

That is, 1 is a water tank, 2 is a mounting plate on which the pump 3 is placed, and 4
is the cover.

The pump 3 is provided with a suction port body 5, a discharge port body 7 equipped with a water tap 6, and a detection port body 9 equipped with a water cutoff switch 8.

The aquarium 1 is provided with an overflow eye 10, a ball tap 12 with a float 11, and an inspection port 13 as an opening.

This inspection port 13 is closed with a lid plate 15 via a gasket 14, as shown in FIG.

Thus, water is replenished into the water tank 1 from the ball tap 12, and the water level is regulated within the displacement range of the float 11.

Water in the water tank 1 is pumped up by the drive of the pump 3 and is supplied through the water tap 6 from the outlet body 7 .

By the way, since the water supplied from the ball tap 12 has a certain amount of water pressure, it hits the water surface and is repelled as water droplets.

A portion of the splashed water drops falls on the inspection port 13 located near the ball tap 12.

The lid plate 15 is separated from the aquarium 1 by 14 minutes.

That is, since the inspection opening 13 and the inner peripheral edge of the gasket 14 form recesses in the vertical portion of the water tank 1, the water droplets accumulate therein.

Originally, gaskets are used to prevent leakage, but water may leak out due to lack of elasticity, damage, loosening of bolts 16, etc. due to long-term use.

Although it is necessary to retighten the bolt 16 and the cap nut 17 each time, there is a limit to preventing seepage.

This type of phenomenon applies not only to water tanks used in water pressure equipment, but also to water tanks for air conditioning equipment and all other water tanks. The same applies when attaching via a packing.

The present invention was made with attention to the above circumstances, and its purpose is to have a relatively simple structure, but to
The present invention aims to provide an aquarium that improves waterproofness and reliability by preventing splashed water droplets from seeping out from a closed opening.

An embodiment of the present invention will be described below with reference to FIGS. 3 and 4.

In the figure, 20 is a water tank body used, for example, in a water supply pressurizing device.

An inspection port 21, which is an opening, is provided at the upper end of the vertical portion of the water tank body 20.

A plurality of mounting holes 22 are bored around the inspection port 21 at predetermined intervals.

23 is a lid plate made of the same material as the aquarium body 20.

An annular gasket 2 is provided along the peripheral edge of one side of the lid plate 23.
4 is attached.

The packing 24 is made of an elastic member such as synthetic leather rubber, and has a thin wall thickness.

The above-mentioned mounting holes 22 are provided in the cover plate 23 and the gasket 24.
A through hole 25 is integrally formed at a position opposite to.

A splash protection gasket 26 is attached to the inside of the gasket 24.

This splash protection gasket 26 is made of an elastic material such as soft synthetic rubber or foam material, and is extremely thick.

Its dimensions are formed to be 2 to 37 FL/m thicker than the total thickness of the packing 24 and the water tank body 20.

Moreover, it is preferable to make the peripheral edge part larger than the peripheral edge part of the inspection port 21.

In this way, the gasket 24 and the splash prevention gasket 26 are attached to the lid plate 23 and can be handled as one unit.

When attaching to the water tank body 20, first insert the splash protection gasket 26 into the inspection opening 21.

This gasket 26 is larger than the inspection port 21, so it is easy to insert it, but it is forced into place using its elasticity.

Next, insert the bolts 27 into the mounting holes 22 through the through holes 25 from the lid plate 23 side, and attach the aquarium body 20.
A nut packing 28 is fitted onto the end of the bolt 27 protruding from the inner surface of the bolt 27, and a cap nut 29 is screwed into the bolt 27.

If the bolt 27 and cap nut 29 are tightened together,
The gasket 24 receives a clamping force between the lid plate 23 and the aquarium main body 20, and the splash-preventing gasket 26 fits into the inspection opening 21, and its end surface protrudes toward the inner surface of the aquarium main body 20.

On the other hand, a ball tap 30 having a float (not shown) is provided near the inspection port 21.

This ball tap 30 communicates with a water supply source, and the inner end of the water tank body 20 is bent downward.

Although not shown in the drawings, the water tank body 20 is connected to an overflow eye body, a drain mouth body, etc., and a pump is mounted on the lower part via the upper cover, and from this a pumping mortar body, a detection mouth body, etc. are attached to the inner bottom. It will be extended towards.

The pump is provided with a discharge port provided with a water tap.

Thus, when the level of the stored water in the water tank main body 20 decreases, water is replenished from the ball tap 30.

This make-up water has some water pressure, and since the distance between the ball tap 30 and the water surface is large, the water is repelled from the water surface as shown by the broken line arrow.

A portion of the splashed water drops head toward the inspection port 21.

However, the splash protection gasket 26 fits into this,
Since the gasket 26 protrudes toward the inner surface of the water tank body 20, all water droplets flow down along the protruding end surface of the gasket 26.

Therefore, even a small drop of water will not enter the inspection port 21 and will not leak from between the lid plate 23 and the tank body 20.

In this way, the splash seal 26 repels water droplets and prevents them from leaking to the outside, so the lid plate 23 can be attached to the aquarium body 20 using the bolts 27 and cap nuts 29 as in the above embodiment. In addition to using a simple and inexpensive structure such as a roller catcher, it is sufficient to mount it so that it does not leak from the part.

Further, in the above embodiment, the splash protection gasket 26 is made of an elastic material such as synthetic leather rubber, but it is not limited to this, and even a hard material can have sufficient effect as long as it can fit into the opening. There is.

Further, in the above embodiment, an inspection port is used as the opening 21, but the invention is not limited to this. For example, an opening for installing instruments and piping on a mounting plate may be used. There may be.

Further, in the above embodiments, the explanation has been made with application to a water supply pressurizing device, but the present invention is not limited to this, and of course can be applied to water tanks used in other devices.

As explained above, according to the present invention, the opening provided in the vertical part of the aquarium body is opened and closed by the lid plate, and the lid plate fits into the opening and protrudes from the inner surface of the aquarium body. Since we have provided a gasket to prevent splashing, there are no concave areas where water drops can collect in the vertical part of the tank body, which is the case with conventional aquariums.
It is possible to reliably avoid splashing water droplets that fly toward the opening.

Therefore, it is possible to prevent water from seeping out from the opening, thereby improving waterproofness, and also improving durability and reliability.
