JPH08238444A - Rotary nozzle by high pressure water - Google Patents

Abstract

PURPOSE: To prevent rotational performance from being affected by high pressure water. CONSTITUTION: In a rotary nozzle, a primary nozzle 2 attached to a main body 1, a secondary nozzle 3 which receives the reaction of high pressure water ejected from the primary nozzle 2, and a rotor 4 connected with the secondary nozzle 3 rotate around the main body 1 through a rotary bearing 5. Since high pressure water does not act on the rotary sliding part, the rotational performance of the nozzle is not affected by the high pressure water.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used in equipment having a nozzle using high pressure water.

[0002]

2. Description of the Related Art Some conventional rotary nozzles use a reaction of high-pressure water to rotate jet water. In this case, high-pressure water is struck against the rotary blades or the rotor for rotation, but the rotating portion has a structure of a slide bearing, which adversely affects the durability of the rotary performance.
Further, since the high-pressure water path is in the rotation support portion, it is affected by watertightness or water quality, or the direction of the jetted water, which also adversely affects its durability. In addition, in order to smooth the rotation of a certain type of rotary nozzle, a clearance is required in the rotary sliding part, but if it is too large, high pressure water may flow into the gap and adversely affect the rotation. there were.

[0003]

In the rotary nozzle, the structure of the rotary part has a great influence on the rotary performance and durability, and it cannot be used for a long time under high pressure and in all directions. There are drawbacks.

Therefore, an object of the present invention is to provide a rotary nozzle in which high-pressure water does not affect the rotary performance and durability.

[0005]

In order to solve this problem, the present invention relates to a rotary nozzle using a reaction of high-pressure water, and a main body having a primary nozzle for injecting the high-pressure water and a main body provided with the main nozzle. It is characterized in that it has a rotating body that is capable of rotating in response to the injection in cooperation with the next nozzle and its secondary nozzle, and a rotary bearing portion that supports the rotating body.

[0006]

According to the present invention, the high-pressure water sprayed from the primary nozzle collides with the secondary nozzle, and the rotary body connected to the secondary nozzle is rotated by the reaction of the high-pressure water, so that the jetting direction of the high-pressure water draws a spiral shape. It spouts into rotation.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, one embodiment of the present invention will be described with reference to FIGS. As shown in FIG. 1, the rotary nozzle has a main body (1), a primary nozzle (2), a secondary nozzle (3), a rotating body (4), and a rolling bearing portion (5).

As shown in FIG. 1, the primary nozzle (2) is mounted on the main body (1) and the secondary nozzle (3) is connected to and integrated with the rotating body (4). Further, the rotating body (4) is supported by the main body (1) via the rolling bearing (5), and can smoothly rotate around the main body (1).

Next, the operation of this rotary nozzle will be described.
As shown in FIG. 1, first, high-pressure water (A) enters the main body (1) and is jetted straight from the primary nozzle (2).

The high-pressure water (B) ejected from the primary nozzle (2) collides with the secondary nozzle (3) and its traveling direction is changed to high-pressure water (C). At this time, the secondary nozzle receives a reaction in the direction (a) as shown in FIG.
The rotating body (4) connected to this secondary nozzle (3) is (b)
Start a rotational movement in the direction of.

The rotating body 4 is mounted on the body 1 via a rolling bearing 5.
Therefore, the high-pressure jet water C is jetted rotationally so as to draw a spiral shape.

Further, at this time, the high pressure water does not flow into the rotary sliding portion at all, so that it is not necessary to maintain the watertightness of the water passage, and the sliding portion is abraded by impurities contained in the water. No phenomenon occurs.

On the other hand, since the secondary nozzle (3) is connected to the rotating body (4) and is mounted on the main body (1) through the rolling bearing (5), it is possible to inject in all directions. .

Further, as shown in FIG. 3, since the rotation of the nozzle is freely controlled, the rotary motion is transmitted from the rotary drive source (6) through the transmission body (7), and a stable rotary nozzle can be formed. Is.

[0015]

According to the present invention, the high-pressure water sprayed from the primary nozzle does not affect the rotating performance of the rotating secondary nozzle, and is not affected by the watertightness / spraying direction and water quality at all. It is possible to form a high-pressure jet nozzle.

Claims (3)

[Claims] 1. A rotary nozzle that forms a rotary jet nozzle by causing a water flow jetted straight from a primary nozzle to collide with an inner wall of the secondary nozzle and causing a reaction body to rotate to rotate the rotary body. 2. A rotary nozzle in which the rotating body rotates with respect to the main body via a rolling bearing, so that the rotation durability is extremely high. 3. A rotary sliding part for supporting a rotary body is not associated with a high-pressure water path, and therefore high-pressure water does not flow into the rotary sliding part, so that the high-pressure water is not affected at all. nozzle.
