Description

[Detailed description of the invention] The present invention relates to the configuration of a flow rate adjustment device for a water pipe.
In particular, the present invention relates to a flow rate regulating device that is installed at the end of a water pipe provided for taking in or draining water for rinsing, so that the amount of water taken in or drained can be easily adjusted.

drawing waterways for irrigation from constructed waterways or streams;
Drainage channels may be formed in the direction from the rice fields, such as drainage ditches.

These waterways are generally in the form of a moat,
The flow rate is regulated by a weir.

In addition, when these weirs are large, the flow rate is adjusted by opening and closing the weir plates automatically or manually, but for small canals that are built directly into rice fields, the width of the moat is adjusted. The flow rate is adjusted by altering or by placing or removing stones or other fill materials.

Therefore, in such small canals, not only special manual labor is required to adjust the flow rate, but also the height of the fill material must be selected depending on the amount of water intake and the drainage water level, which takes time. .

The flow of water in these canals also causes water conflicts during drought periods.

In addition, waterways such as those described above are formed not only for agricultural purposes but also for ponds for eel farming, etc., and the water volume is adjusted in the same way.

For these reasons, there has been a desire for a flow rate adjustment device that can easily adjust the flow rate and can be provided at low cost.

The present invention has been made with attention to these points, and aims to provide a flow rate regulating device that satisfies all of the above-mentioned matters. An opening/closing cover plate is provided at the end of the water intake receiving side or the drainage outlet side, and the cover plate is configured to be set in a free position from the open end of the pipe.

The present invention will be explained in detail below based on the drawings, but the drawings show an example of a specific implementation of the present invention, and the present invention is not limited to the example shown in the drawings. The same implementation is possible even with changes or changes in design.

FIG. 1 is an explanatory cross-sectional view showing an example of installing a water pipe equipped with the flow rate regulating device of the present invention, and 1 and 2 indicate appropriate ridges, which are constructed with earth mounds or concrete to form a waterway 3. It is formed.

For example, 5 indicates a paddy field, and a vibro is buried in order to pass the water 4 from the waterway 3, and the pipe used for the pipe may be a clay pipe, a metal pipe, or a resin pipe mainly made of synthetic resin, which is conventionally used for water passage. Alternatively, the pipe may be applied after being subjected to corrosion-resistant treatment, but synthetic resin pipes are particularly recommended because they are inexpensive and have excellent corrosion resistance and workability.

Therefore, in the following embodiments, a water-passing vibro constructed of a synthetic resin pipe will be described.

A flow rate regulating device as shown at 7 is provided on the water receiving side of the water passing vibro, and the main part of the present invention relates to the structure of the flow rate regulating device.

Therefore, the water passing vibro is not limited to the horizontal arrangement as shown in the figure, but may be provided at an angle.

As shown in an enlarged and partially cutaway view of FIG. 2, the flow rate regulating device 7 is assembled to the support tube 9 and inserted into one end of the water-flowing vibro.

Also, inside the support tube 9, there is a section line III-I in FIG.
As shown in FIG. 3, the arm rods 13,
13', 13" and 12.12', 12"(12"
(not shown in FIG. 2) is provided with a support shaft 14, and a metal fitting 10.11 is fixed to the latch of each arm rod to support the support shaft 14.

Further, the spindle 14 is formed with a narrow diameter portion 15 and an end portion 17,
The narrow diameter portion 15 is passed through and fixed to the metal fitting 10.

Reference numeral 16 indicates welding as the fixing means.

Although the other metal fitting 11 is shown screwed onto the end portion 17, it may be fitted loosely or fixedly. Convenient for holding position.

Further, the metal fittings 10.11 and the support shaft 14 are made of a highly corrosion-resistant metal material, and brass is preferable for practical use.

Further, the support cylinder 9 and each arm rod 12, 13 may be made of steel and adhesively bonded to the water passing vibro, or may be molded from a synthetic resin material in the same way as the water passing vibro.

In the latter case, the metal fittings 10 and 11 are attached to each arm rod 12,
13 by insert molding means, and each arm rod 12, 13 is gripped into the support tube 9 by resin welding or adhesive.

Note that, if necessary, the inner part of the support tube of these arm rods 12 and 13 can be similarly configured by being fixed from the outer periphery of the support tube 9 with tap screws, etc., and the arm rod The shape of 12, 12 can also be freely selected.

Although these support shafts 14 are shown as being formed in the support tube 9 and inserted into the water-flowing vibro, they can also be installed directly on the inner surface of the end of the water-flowing vibro without using the support tube 9 by the same means as described above. You can also do so.

Further, the constricted portion 8 of the water-flowing vibro shown in FIG. 2 is formed to regulate the insertion distance of the support tube 9 and to prevent sediment accumulation during flowing water, but it may be omitted.

Furthermore, the support tube 9 and the water-flowing vibro are integrated using a suitable adhesive or bonding agent, but as shown in FIG.
4. When fastened with 24' and 24'' (not shown), it is convenient because it can be replaced freely.

In addition, when using a clay pipe or a concrete pipe as a water-flowing vibro, it is recommended to use a support tube 9 made of metal or plastic.

The support tube 9 is also advantageous in that the length of the support tube 9 protruding from the existing vibro can be changed depending on the conditions of the paddy field or field.

A closing cover plate 13 is provided on the support shaft 14 provided in this manner so as to be movable toward or away from the end face of the support tube 9 or the end face of the water-flowing vibro, and is held in a free position. It is configured as follows.

That is, the cover plate 18 shown in the figure is formed of a disk made of a synthetic resin material or a metal material, and a screw metal fitting 19 made of a corrosion-resistant metal similar to the metal fitting 11 is fixed at the center thereof.

Therefore, if the cover plate 18 is rotated in either direction, it will move to the left or right in the drawing as described above.

Also, gaskets 20 and 21 are provided on the support cylinder side of the cover plate 18.
, especially the packing 20 along the cutting line IV in Fig. 2.
-IV is formed of an annular body along the outer periphery of the lid plate 18, as shown in FIG.

Further, the gasket 21 is attached to the threaded metal fitting 19 and its outer periphery on the support cylinder side, but may be omitted depending on the case.

However, if the cover plate 18 screwed onto the support shaft 14 is moved to the left in the drawing and brought to the position shown by the dotted line in Fig. 2, the opening surface of the support tube 9 can be closed, thereby allowing water to flow. can be stopped.

In addition, the amount of water flowing is determined by the distance between the opening surface of the support tube 9 and the cover plate 18, and in order to hold the cover plate 18 in a predetermined position so that it does not move to the right or left side of the drawing position, a lock nut such as a threaded screw 22 is used. It is sufficient if they are screwed together adjacently.

That is, by loosening the threaded screw 22, the cover plate 18 can be rotated, and the end 17 formed on the support shaft 14 can be locked at an appropriate position.

In addition, when the water flow direction is on the right side, the cover plate 18 is attached to the support shaft 14.
The cover plate 18 is loosely fitted into the end portion 17 of the cover plate 18 with the screw 22.
It is also possible to restrict movement of the support tube 9 in a direction away from the support tube 9.
