Can do. In addition, a portion for joining the injection portion to the ball portion is not necessary, so that the protrusion amount of the injection portion can be reduced and the cost can be reduced.

  Moreover, if it comprises with brass, while being able to suppress the corrosion by seawater, it can process easily. Therefore, it can be preferably used for ships.

It is a figure showing the structure of the nozzle which concerns on one embodiment of this invention. It is a figure showing the structure of the conventional nozzle.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 shows a configuration of a nozzle according to an embodiment of the present invention. FIG. 1 (A) shows an appearance viewed from the injection side, and FIG. 1 (B) shows an appearance viewed from the side. FIG. 1C shows a cross-sectional structure. The nozzle 1 is preferably used for, for example, a ship, and includes a bearing member 10, a ball portion 20, an injection portion 30, and a pressing member 40. The bearing member 10, the ball part 20, the injection part 30, and the pressing member 40 are preferably made of brass.

  The bearing member 10 has the 1st flow path 11 inside, and the both ends of the 1st flow path 11 are open | released. The cross-sectional shape of the first flow path 11 is, for example, a circle. A ball receiving portion 12 is provided on the inner surface on one end side of the bearing member 10, that is, on the inner surface on one end side of the first flow path 11. The ball receiving portion 12 includes, for example, an inclined portion 12A that is inclined so that the diameter increases from the other end side toward the one end side, and an extended portion 12B that is extended with the same diameter on one end side of the inclined portion 12A. have. The diameter of the extending portion 12B is the same as or larger than the maximum diameter of the inclined portion 12A.

  For example, a screw portion 13 for screwing the presser member 40 is provided on the outer peripheral surface on one end side of the bearing member 10. For example, the presser member 40 is screwed on the other end side of the screw portion 13. When performing, the holding | maintenance part 14 holding the bearing member 10 protrudes and is provided. It is preferable that the holding | maintenance part 14 has 6 surfaces arrange | positioned equally in the circumferential direction, for example. On the other end side of the bearing member 10, for example, a connection portion 15 for connecting a pipe (not shown) is formed, and a screw is formed on the outer peripheral surface, for example.

  For example, the ball portion 20 is disposed so as to be rotatable with respect to the ball receiving portion 12 of the bearing member 10 and has an outer surface formed in a spherical shape. Inside the hole portion 20, for example, a second flow path 21 having both ends opened from the bearing member 10 toward the opposite side is provided so as to communicate with the first flow path 11. The ball portion 20 and the ball receiving portion 12 are in line contact, for example, and the first flow path 11 and the second flow path 21 are joined. The cross-sectional shape of the second channel 21 is, for example, a circle.

  The injection unit 30 is provided on the opposite side of the bearing member 10 corresponding to the second flow path 21 of the ball unit 20. The injection unit 30 is formed integrally with the ball unit 20 and constitutes one part together with the ball unit 20. Inside the injection unit 30, for example, a third flow path 31 is provided in which both ends are open and an end on the second flow path 21 side communicates with the second flow path 21. The cross-sectional shape of the third flow path 31 is, for example, a circle. The diameter of the third flow path 31 is smaller than that of the second flow path 21 so that the second flow path 21 can be narrowed and fluid can be ejected.

  For example, a V-shaped groove 32 extends in one direction on the end surface of the injection unit 30 opposite to the ball unit 20, and the shape of the end surface of the third flow path 31 is opposite to each other, for example. It has a shape in which arcs that curve so as to protrude toward the side are joined at both ends. Thereby, the fluid supplied to the bearing member 10 spreads in the extending direction of the groove 32 from the injection unit 30 and is ejected in a fan shape.

  The pressing member 40 has, for example, an annular shape, is provided so as to expose the injection portion 30 and cover a part of the ball portion 30 from the opposite side of the bearing member 10, and is externally fitted to the bearing member 10. On the inner peripheral surface of the pressing member 40 on the bearing member 10 side, for example, a screw portion 41 that is screwed into the screw portion 13 of the bearing member 10 is provided. On the outer peripheral surface of the pressing member 40, for example, a grip portion 42 that is gripped when the pressing member 40 is screwed is provided. The gripping part 42 preferably has, for example, six surfaces that are equally arranged in the circumferential direction.

  For example, the nozzle 1 is arranged as follows. First, the connecting portion of the bearing member 10 is connected to a pipe (not shown), and the ball portion 20 is disposed on the ball receiving portion 12 of the bearing member 10. Next, a part of the ball part 20 is covered with the presser member 40, and the ball part 20 is rotated before the presser member 40 is externally fitted to the bearing member 10 to determine the position of the injection part 30. After setting the position of the injection part 30 to a desired position, for example, the screw part 13 of the pressing member 40 is externally fitted by being screwed to the screw part 13 of the bearing member 10. Thereby, the ball | bowl part 20 and the injection part 40 are fixed.

  As described above, according to the nozzle 1 according to the present embodiment, since the ball portion 30 and the injection portion 40 are integrally formed, it is possible to reduce the number of components and facilitate component management. And cost can be reduced. Moreover, the part for joining the injection part 40 with respect to the ball | bowl part 30 is unnecessary, and while being able to make the protrusion amount of the injection part 40 small, cost can be reduced.

  Moreover, if it comprises with brass, while being able to suppress the corrosion by seawater, it can process easily. Therefore, it can be preferably used for ships.
