DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a trap with a partition plate.

[0002]

2. Description of the Related Art In general, the inside of a pipeline made of a PVC pipe is formed smoothly without a step to prevent a blockage accident. In addition, a drainage basin with a PVC U trap is interposed in such a pipeline. In addition, the U-trap has a self-cleaning function, which cleans the pipeline by the drainage water itself, so that there is no stagnation, and therefore, there is no clogging accident due to its high flush-out effect.

However, a large amount of highly viscous oil from a commercial kitchen, a large amount of earth and sand from a drain, a large amount of hair from a barber shop or a beauty salon, a large amount of shavings and cloth waste from a commercial laundry, If it unexpectedly flows into a PVC pipe line with a U trap over a dust trap such as a strainer, especially high-viscosity oil cannot be caught by the strainer. Accidents are likely to occur. Of course, it also occurs in home drainage of ordinary households.

[0004] However, even if a general pipe line is blocked,
For example, if a long cleaning rod is inserted from the upstream side, this blockage can be easily resolved.

On the other hand, the U-trap is provided with various structures and functions in order to cope with various drainage facilities in a variety of terrain, geology, buildings, and the like. I am working on a flexible basis.

For example, in a merging type U trap 100 shown in FIG. 8, a pair of main pipe connecting portions 10 are provided on both sides from a main body 102 having a connecting portion 101 for an inspection tube provided above.
3, 103 and two lower branch connections 104,
One main pipe flow path and two branch pipe flow paths are provided, and U-traps 105, 105 are connected to these branch pipe connection sections 104, 104, respectively. In addition, 7 is an inspection tube, 14 is a main pipe in a house, and 10 is a branch pipe.

Therefore, such a U trap 100
Then, two U traps 10 in one main body 102
5, 105, and various cost reductions have been achieved (see, for example, Japanese Utility Model Publication No. 4-37987), as well as two branch pipes 10, which are not provided with an instrument trap.
10 is advantageously used in drainage facilities laid in close proximity.

In addition, if the U trap 100 is brought to the construction site, one of the two branch pipe connecting portions 104, 104 may be closed with a plug, or the main pipe connecting portion 103 may be closed.
If the upstream side is closed with a plug, the branch pipe 10 can be applied to a single drainage facility, and can also be applied to a U trap for a starting point.

[0009]

It has been found that the above-mentioned prior art has the following problems.

[0010] In the U trap shown in Fig. 8, if two or more branch pipes having a small nominal diameter are used, the occurrence rate of the blockage accident as described above increases accordingly.
When cleaning is performed by inserting a cleaning rod from the upstream, it is difficult to pass the cleaning rod because it is a U trap.

If a U-trap to which two or more branch pipes can be connected is brought to a construction site and its use is to be expanded, plugs can only be attached and detached, so the use is limited.

The present invention has as its main object to solve such different kinds of problems all at once, and has another object to further expand the applications.

[0013]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides: 1) a main pipe flow path and a branch which merges with the main pipe flow path and is integrally extended from a side surface of the main body. A pipe flow path;
A partition plate that separates the main pipe flow path and the branch pipe flow path, and that can be freely inserted and removed from an upwardly directed inspection tube provided in the main body;
In the main body provided with the above, a water-sealing part is formed by the partition plate and the branch pipe flow path, and the main pipe flow path is formed as one in the trap with the partition plate having the overflow part formed in the partition plate. In addition, a plurality of branch pipe channels are provided, and the partition plate is moved in and out, whereby it is possible to easily prevent or eliminate a blockage accident of a branch pipe connected to these branch pipe channels. And 2) a trap with a partition plate having two branch pipe channels by providing a partition weir between the branch pipe channels according to claim 1.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail with reference to embodiments shown in the accompanying drawings. 1 is a longitudinal sectional view of an embodiment of the present invention, FIG. 2 is a plan view of FIG. 1, and FIG.
4 is a partially detailed view of FIG. 1, FIG. 5 is a longitudinal sectional view of another embodiment, and FIG. 6 is a plan view of FIG.
7 and 8 of the conventional example are omitted.

A trap with a partition plate according to an embodiment of the present invention is based on a generally used small-diameter injection-molded PVC square muffler. For example, as shown in FIG. 100 mmφ, 200 mmφ for the inspection cylinder, and 75 mmφ for the branch pipe are convenient.

First, an outline of the trap 1 with a partition plate of the embodiment will be described. 1 to 3, a main body 3 having an inspection tube connecting portion 2 provided thereon is provided with main pipe connecting portions 4 and 4 forming an inlet and an outlet, respectively. A pair of upwards, which form a main flow path 5 having a substantially horizontal shape of the main and main pipes 4 and 4 and which merge at right angles to the main flow path 5 and extend integrally from the side surface of the main body 3 Inspection in which L-shaped branch pipe passages 6 and 6 are formed, these main pipe passages 5 and a pair of branch pipe passages 6 and 6 are respectively partitioned and connected to the above-mentioned inspection tube connecting portion 2. Partition plates 8 and 8 are provided, which can be moved in and out of the cylinder 7 (see FIG. 7).

The height h of this partition plate 8 is
4 and the diameter d of the entrance / exit of the branch pipe flow path 6 are made larger than the diameter D of the branch pipe flow path 6 and the partition plate 8 to form a pair of water sealing portions 9 and 9;
As the trap, the U trap shown in FIG.
It has the same function as 00. Therefore, it can be said that this trap 1 with a partition plate is a twin trap type of a confluence type.

The above-mentioned twin-trap type trap with a partition plate 1 is composed of two branch pipes 10,
10 (see FIG. 7) can be conveniently used for drainage facilities laid in close proximity, and the sewage gas of the main flow path 5 is reduced to 2 by these water sealing portions 9 and 9 and the overflow portion 12 of the partition plate 8. Branch pipe 1
0, 10 so that the building 11
(See FIG. 7). As a result, compared to the case where two traps with partition
Equipment costs can be reduced by half.

Then, one or both of the branch pipes 1
If a blockage accident occurs at 0, the accident can be easily resolved by removing the partition plate 8 and inserting a cleaning rod or jet cleaning nozzle into the branch pipe 10 from the inspection cylinder 7 or the building 11 side.

As shown in FIG. 7, an instrument trap 13 is provided in the building 11.
In general, the cautionary note of double trap prohibition is thoroughly provided between the main house 14 and the main house 14. However, if the trap 100 is inadvertently interposed as shown in FIG. 7 or FIG. When a double trap is formed in the branch pipe 10 in the middle of the pipe, and drainage flows into the branch pipe from upstream, the drainage capacity is extremely reduced, the drainage time is prolonged, and eventually, a blockage accident is caused. If the formation of such a double trap is found after the laying work, the partition plate 8 is removed from the inspection tube 7 and the water sealing portion 9 is eliminated to avoid the double trap (for example, see Japanese Patent Application Laid-Open No. 9-134).
No. 90), and thus a blockage accident can be prevented.

Further, the trap 1 with the partition plate can be used for other purposes without using both or one of the two partition plates 8. For example, if one of the two partition plates 8 is not used, the present invention can be applied to, for example, a two-joining type having no instrument trap on one side as shown in Japanese Utility Model Laid-Open No. 3-36081.

That is, the drainage system is constituted by a drainage pipe of a washing machine near a wash basin provided with an instrument trap, a drainage pipe for a bathroom floor with an instrument trap, and a bathtub without an instrument trap. Not only is it convenient for drainage equipment, but also a plug (not shown) at the main pipe connection 4 on the inlet side
Then, it can be substituted for a trap with a partition plate of a twin trap type of a starting type described later.

Next, each part of the trap 1 with a partition plate of this embodiment will be described in detail. The body 3
The inspection tube connecting portion (reception port) 2 provided upward is opened by, for example, 57 mm from the pipe axis of the main pipe channel 5 toward the branch pipe channels 6 and 6, and each width is about 90 mm. Since the mounting positions of the pair of partition plates 8, 8 substantially coincide with the center of the connecting portion 2 for the inspection tube, these partition plates 8, 8 are located within the opening of the inspection tube 7, 7 can be freely moved in and out, and the body 3 can be made more compact.

A partition plate groove 15 for mounting the partition plate 8 (the groove 15 is not necessarily vertical, but may be slightly inclined toward the main channel 5. Only one of the pair is described) is formed on the outlet side of the branch pipe flow path 6, and is formed substantially vertically in the pipe wall 16 on one side of the main pipe flow path 5 and on one side of the partitioning weir 17. , At its lower end. The partitioning weir 17 is raised in the middle of the pair of branch pipe channels 6 and 6 in parallel with the pipe axis, and the top is higher than the overflow portion 12 of the partition plate 8.

By providing the partitioning weir 17, the branch pipe flow path 6 can be configured as an approximate U trap, and the flash-out effect can be exhibited.

In the groove 15, since the entire shape of the partition plate 8 is formed in the shape of a scooping piece of a shovel as described later (see FIG. 3), the groove 15 has a U-shape opening upward as viewed from the branch pipe flow path 6. The lower curved portion is also formed as a groove in the pipe bottom of the branch pipe flow path 6. Accordingly, ribs are formed on the outer surface of the main body 3 by the group 15 to reinforce the main body 3.

An upwardly directed branch port 18 is formed at the inflow port of the branch channel 6, and the center of the branch pipe port 18 is 170 mm away from the center of the inspection tube connecting portion 2, and
An opening is provided at a position higher than the overflow portion 12 of the partition plate 8, and a foot 19 extends in the branch pipe channel 6 immediately below the branch pipe spout 18.

Next, the partition plate 8 will be described. Partition plate 8
Is made of hard PVC, and is formed of a shovel-like plate as shown in FIG. The valve plate 20 of the partition plate 8 is formed to have the same thickness.
The jigs portion is / 3 or less, a window is opened above the jigs portion, and the overflow portion (wear) 12 of the trap is provided. Accordingly, the partition plate 8 is inserted into and removed from the groove 15 by gripping the handle 21.

Surrounding ridges 22 are provided on the periphery and the upper side of both sides of the valve plate 20, and on the outer periphery of the ridges 22, an insertion portion (square dropping portion) to be inserted into the groove 15 is provided. ) 23 are provided. In particular, the insertion portion 23 is formed in a wedge shape with a slope having a thicker upper portion and a thinner lower portion.

Next, the rubber packing 24 will be described.
In FIG. 1, the rubber packing 24 is mounted and fixed to the groove 15 in advance with an adhesive or the like. The rubber packing 24 is made of synthetic rubber, and is formed in a U-shape with the whole opened upward.

Next, another embodiment of the present invention will be described. As shown in FIGS. 5 and 6, the trap 25 with a partition plate is a twin trap type of a starting point type, and a main body 26 is provided with a main pipe connection portion 27 having only an outlet.

That is, a main pipe flow path 28 having the main pipe connection portion 27 is formed in the main body 26, and a pair of branch pipe flow paths 29, 29 are formed in parallel with the pipe axis of the main pipe flow path 28. Is formed. The other components are the same as those of the trap with partition plate 1 described above, and are denoted by the same reference numerals, and description thereof will be omitted.

In the traps 1 and 25 with a partition plate, a pair of grooves 15 and 15 are provided on the outlet side of the branch pipe passages 6 and 29 and on one side of the main pipe passages 3 and 28. Tube wall 16
And on both sides of the partitioning weir 17, respectively.
The present invention is not limited to this, and the grooves 15 are formed without the partition weir 17 at the outlet side of the branch pipe passages 6 and 29 so that the partition plate 8 is mounted along the pipe wall 16. May be.
In this case, it is needless to say that the partition plate 8 can be moved in and out of the inspection tube 7.

Further, the partition plates 8 may not be formed as a pair but may be formed of a perforated or non-perforated partition plate which does not form one trap, and may also be used as two partition plates. In this case, of course, one group is provided.

[0035]

According to the present invention, since a plurality of branch pipe channels are joined to one main pipe channel in a trap with a partition plate, two or more simple trap plates with a partition plate are arranged side by side. In addition to reducing product costs and construction costs, as well as saving installation space, the incidence of blockage accidents is high just by merging from multiple traps, but if even a partition plate is taken out, such a high probability of blockage Accidents can be prevented and resolved.

In addition, it is possible to use the trap with the partition plate for other purposes by detaching the partition plate and closing the branch pipe with the plug, thereby expanding the use.
