Description

[Detailed description of the invention] [Field of industrial application] The present invention is a nozzle that is mainly used in snow-melting equipment for roads and roofs in snowy regions, watering equipment for farms and lawns, fountain equipment for parks, etc. It is related to the device.

[Prior Art] The same applicant as the present applicant provided the industry with a type of water control block that can be operated with a hexagonal wrench as shown in Japanese Patent Application No. 100254/1982.

[Problems to be Solved by the Invention] The conventional type described above is as shown in Fig. 5, and while operating a hexagonal wrench, the hexagonal wrench blocks the water spout, so the amount of water spouted is checked. In addition, since there is a retaining ring 19 on the water control body and there are many threaded parts, the structure is complicated and the cost is relatively high.

[Means for solving the problem] In the present invention, a water control body 2 having a water discharge hole 1 bored in the upper surface is inserted into a bottomed cylindrical outer casing 3 so as to be freely twistable. A guide groove 4 and a pin 5 are provided on the outer periphery of the top body 2 and the peripheral wall of the outer casing 3 so as to be slidably fitted to each other. The water guide hole 6 and the inlet hole 7 are drilled so that they do not communicate when the rotation angle is reached, and the outer periphery of the upper end of the water control piece 2 is made into a prismatic shape to form a box wrench fitting part 8. The gist of this invention is that a space 9 for inserting a box wrench is formed around the fitting part 8, and this gist attempts to solve the above-mentioned problems.

[Embodiment] The first embodiment shown in FIGS. 1 to 3 is a short bar-shaped metal water control body 2 with a water discharge hole 1 bored on the top surface.
is inserted into a bottomed cylindrical metal outer casing 3 with an outward flange 10 provided on the opening edge so that it can be twisted freely as a seal with an O-ring 11. The peripheral wall is provided with an endless ring-shaped guide groove 4 and a driven pin 5 that are slidably fitted into each other, and inclined water guide holes 6 and Snow melting water inlet hole 7
These water guide holes 6 and inlet holes 7 communicate with each other and are open when the water control piece 2 reaches a predetermined rotation angle, and are closed and do not communicate when the water control piece 2 reaches a certain rotation angle. In addition, the outer periphery of the upper end of the water control piece 2 is shaped like a hexagonal column to form a box wrench fitting part 8, and the part surrounding the box wrench fitting part 8 on the top surface of the outer casing 3 is recessed. In each case, a space 9 for inserting a box wrench is formed.

In the second embodiment shown in FIG. 4, the guide groove 4 is shortened so that when the pin 5 abuts against one end of the guide groove 4, the water guide hole 6 and the inlet hole 7 communicate with each other and abut against the other end. It is designed so that there are times when there is no communication.

In the present invention, the water control body 2 and the outer casing 3 may be made of plastic with good sliding properties.
In some cases, a male mounting thread is provided on the outer periphery of the pipe, and this male thread is used to screw onto the internally threaded water pipe 13.

[Function] Since the present invention has the above-described structure, it can be used, for example, by being attached to the upper end of the water pipe 13 as shown in Fig. 3, or as a conventional one shown in Fig. 5. A male screw 15 is provided on the outer periphery of the outer casing 3 to a female screw 14 carved in the upper end of the outer casing 3.
The whole is attached to the water pipe 13 by screwing them together, and a water sprinkling member 17 provided with a diagonal water sprinkling port 16 is attached to the outer end of the water pipe 13 so that it can be twisted and detached. It is. In this way, when the inlet hole 7 and the water guide hole 6 are in communication, a part of the water flowing inside the water pipe 13 is sprayed from the water outlet hole 1 via the inlet hole 7 → the water guide hole 6 in the former case. In the latter usage example, water is sprayed from the water spout 16 via the inlet hole, the water guide hole 6, and the water spout hole 1. In addition, a box wrench (not shown) is attached to the box wrench fitting part 8.
The effective communication cross-sectional area between the inlet hole 7 and the water guide hole 6 can be increased by twisting the water control piece 2 (after removing the water spray member 17 for the latter use). It is possible to increase or decrease the amount of water spouted from the water spouting hole 1 while visually checking it by making it wider or narrower, or to stop the water spouting by setting the same area to zero, that is, a non-communicating state. Furthermore, if it is desired to change the direction of water sprinkling, this can be done by rotating the water sprinkling member 17 to change the direction of the water fountain 16. Furthermore, if it is desired to spray water directly above, this can be done by omitting the water spray member 17.

Note that 18 in the figure indicates a hole for hooking a bottle spanner used when twisting the water spraying member 17.

[Effects of the invention] Since the invention is as described above, it is convenient that when opening/closing the water control block 2 and adjusting the opening degree, it is possible to check the water discharge and the amount of water discharged while performing the same operations. In addition, since there is no retaining ring 19 like in the conventional one and there are only a few threaded parts, the structure is simple and the cost is low.

Claims (1)

[Scope of utility model registration request] A water control piece 2 with a water discharge hole 1 bored on the top surface is inserted into a bottomed cylindrical outer casing 3 so as to be able to twist freely, and the outer periphery of this water control piece 2 and the peripheral wall of the outer casing 3 are mutually connected. A guide groove 4 and a pin 5 are provided which are slidably fitted into the water spouting hole 1 and the wall of the outer casing 3, and communicate with each other when the water control piece 2 reaches a predetermined rotation angle.
