JPH01203508A - Regeneration of defective water spraying nozzle and valve for regeneration of nozzle - Google Patents

Abstract

PURPOSE:To regenerate an old water spraying nozzle for making the amount of water to be spread adjustable by a method in which the valve body of defective water spraying nozzle is removed, a receiving hole to receive new valve body is formed by drilling, and a new body with a water spraying nozzle is attached in a vertically movable manner. CONSTITUTION:A regulator 6 for the amount of water to ne sprayed is removed from the valve hole 7 of a defective waver spraying nozzle (a'), and the drill 11 of a boring machine (b) is inserted into the hole 7 to form a hole 12 to receive a new valve body and an expanded valve hole 7'. The new valve body is screwed into the hole 7' and the hole 12 to close the old water spraying hole 5. The new valve body has a water spraying hole. The existing water spraying nozzle can thus be regenerated to a new water spraying nozzle without cutting off passage.

This is related to.

[Problems to be solved by conventional technology and invention]

If the water spray nozzle in a road snow removal device is used for a long period of time, the water spray hole may quickly become clogged due to frequent car driving over the water spray nozzle or rust and corrosion. This can cause looseness in the threaded joint, resulting in poor water spraying, and malfunctioning of the valve, making it easy to become unable to use it again even after repair, and eventually having to replace it with a new water nozzle. There wasn't.

This work requires cutting out the center of the recess on the road surface to replace the water spray nozzle, performing the replacement work, and then returning the recess to its original position, which has the disadvantage of being extremely troublesome and at the same time increasing costs. Ta.

[Effect]

Among the water sprinkling nozzles a installed on the road surface 8, a defective water sprinkling nozzle a'' that is old and does not spray water well is selected.

Remove the water sprinkling amount adjustment device 6 from the valve lower, insert the drill 11 into the inside of the valve lower to enlarge and drill a predetermined valve stem receiving hole n at 1° of the water passage hole, and at the same time. The valve opening portion 7° is also enlarged to form a valve stem screwing hole 13.

This drilling work is carried out using a water hole drilling drill 11" as shown in the drawing.
, Valve opening drill 11" and valve opening tap 11"°'
These may be formed into one drill 11 and all operations may be performed in one operation, or each operation may be repeated individually.

When a new valve body 14 is screwed into the newly formed valve stem screw hole 13 and the water sprinkling hole 5 of the base body is blocked, a defective water sprinkling nozzle a° is detected.
is regenerated into a new water nozzle.

That is, when water 9 is pressurized into the water passage hole 1, the water 9 enters the rectifying chamber 3 from the valve hole 19 through the vertical groove 19' in the case of FIG. The water is introduced into the introduction hole 20 of the valve stem 17 and is sprayed onto the road surface 8 from the water sprinkling hole 21 .

When the valve body 14 is raised by rotating it with a wrench with a claw that engages with a rotation locking portion n provided on the upper surface of the top disc part, the valve hole 19 is enlarged and the amount of water to be sprayed is increased. When the valve body 14 is lowered, the valve hole 19 becomes smaller and the amount of water sprayed decreases.

In addition, in the case of Fig. 3, a vertical hole 19 is provided at the sliding center of the fitting part, and a valve hole 19 is provided with a T-shaped horizontal hole W in conjunction with this vertical hole 19'°.
When this is adopted, the water 9 is introduced into the rectifying chamber 3 from the valve stem receiving hole through the vertical hole 19' and the horizontal hole 19, and the width of the valve hole 19 at both end openings of the horizontal hole 19 is equal to the width of the valve body 14. The amount of water sprinkled is adjusted by raising and lowering the water.

〔Example〕

The drill drilling machine shown in the drawing is equipped with a drill rotating shaft that can be raised and lowered freely on the machine base supported by a leg lever, and a valve stem receiving hole is drilled in the drill chuck n attached to the lower end of this drill rotating shaft. A drill rod 11 having a water passage hole 11°, a valve opening drilling drill 11°″ for drilling a valve stem screwing hole 13, and a valve opening tap 11 for threading the valve stem screwing hole 13. The drilling work and thread cutting work may be performed by replacing them one after another, or these works may be completed at once using the drill rod 11 as shown.

The rotation locking part n in the drawing shows a case where locking holes are drilled at four locations near the periphery of the top disc part of the valve body W, but a rectangular hole is drilled in the center of the top disc part. You may do so.

The encoder is a communication chamber communicating with the water sprinkling hole 21 and the introduction hole 4, B
is the water pipe, 4 is the 0 ring, and the nod is the water hole blocking pin.

〔Effect of the invention〕

Since the present invention is configured as described above, it has the following effects.

In the regeneration method of the present invention, a defective water spray nozzle is selected from the water spray nozzles installed on the road surface, the water spray amount adjustment device is removed from the defective water spray nozzle, and drilling and screw cutting are performed on the defective water spray nozzle. An excellent feature is that a defective water spray nozzle a° can be regenerated into a new water spray nozzle simply by screwing a new valve body into the part.

In addition, the new valve body has both a water sprinkling hole and a valve hole, and by raising and lowering the valve body, the opening area of the valve hole can be adjusted by the upper edge of the valve stem receiving hole, and water can be introduced into the rectifying chamber through the valve hole. , then water is sprayed on the road surface from the watering hole through the introduction hole,
The valve body can sufficiently adjust the amount of water sprinkled, and the valve body for regenerating the water sprinkling nozzle has excellent practicality and can be regenerated into a water sprinkling nozzle that is comparable in overall heat to the existing water sprinkling nozzle a.
