Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a snow removal nozzle mainly used for removing snow from roads.

[Conventional technology]

Recently, when building a private snow removal road jointly within a town,
In order to deliver water to the end of the road, deep wells are dug to obtain high-pressure water.

For this reason, the water nozzle disclosed in the applicant's earlier application, JP-A-63-20053, had the disadvantage that the force of the groundwater was too strong and the water was blown up into the air, making it difficult to remove snow.

Normally, you would just have to throttle the water flow control valve, but since the water was under high pressure, the more you throttled it, the more groundwater would gush out, making it ineffective.

[The problem that the idea aims to solve]

The present invention solves these problems, and the technical challenge is to provide a water spray nozzle for snow melting that can spray water at the desired amount and pressure by reducing the water pressure to the desired level even when using high-pressure water. .

[Means to solve the problem]

A water flow control valve cylinder 3 is installed vertically at the center of the top part 2 of the water pipe connection cylinder 1, and the lower end threaded portion 4 of the water flow control valve cylinder 3 is screwed into a partition wall 5 provided in the middle of the inner hole of the water pipe connection cylinder 1. A rectifying gap chamber 6 is formed between the outer periphery of the water volume regulating valve cylinder 3 above the partition wall 5 and the inner periphery of the water pipe connecting pipe 1, and a blocking collar 7 is provided on the outer periphery of the water volume regulating valve cylinder 3. A detour water passage part 8 is provided in a horizontally protruding manner, and the position of the shutoff flange 7 is shifted. There are rectification gap chambers 6 in several places on the ceiling 2.
A nozzle hole 10 communicating with is bored, and a water amount adjustment valve 11 is provided in this water amount adjustment valve cylinder 3.

[Effect]

When groundwater is fed to the riser pipe 12, the fed groundwater is discharged from the communication hole 9 and introduced into the rectification gap chamber 6.

Then, the groundwater collides with the cut-off flange 7, weakening the water pressure (water force), and then detours around the detour water passage section 8.
It is sent upward from.

Then, the sent-out groundwater collides with the upper blocking flange 7, the water pressure is further weakened, and is sent out through the detour water passage section 8 and the nozzle hole 10.
Water is sprinkled on the road surface.

That is, the groundwater flows through the blocking flange 7 having the detour water flow section 8.
Since the high-pressure water passes through the detour passage formed by the rectifying gap chamber 6 and the rectifying gap chamber 6, the high-pressure water is gradually weakened and becomes low-pressure water, which is then sprayed.

In the drawing, the blocking flange 7 is provided in two stages, so the water pressure, that is, the water force, is weakened in two stages.

Note that the water amount can be adjusted by adjusting the water amount control valve 11 to adjust the opening degree of the communication hole 9.

〔Example〕

The top portion 2 of the water pipe connection tube 1 is formed by a lid 13 provided at the upper end of the water flow control valve tube 3.
Nozzle hole forming grooves 14 are formed radially at four locations (the number is not limited) on the inclined back surface of No. 3, and nozzle hole forming grooves 14 corresponding to the nozzle hole forming grooves 1
5 is formed on the opening inclined upper surface of the water pipe connecting cylinder 1, and the nozzle hole 10 is formed by the nozzle hole forming grooves 14 and 15 of both.

Although the illustration shows a case in which the blocking flange 7 is provided in two stages, the number thereof is not limited.

Four locations (the number is not limited) on this blocking flange 7.
Although the detour water passage portion 8 is formed by a notched water passage portion, it may be formed by a water passage hole.

The communication hole 9 is a detour water passage part 8 of the lowermost blocking flange 7.
The holes are drilled at different positions.

The water flow control valve rod 11 shown in FIG. 1 is of a screw type, and a rubber cap 16 is provided on the top portion 2.

The water flow control valve rod 11 shown in FIG. 3 is of a cocked type.

Figure 4 shows the core 17 of the pressed product shown in Figure 5.
is housed in the rectifying gap chamber 6, the bottom 18 of this core 17 serves as the blocking flange 7, the notch 21 provided in the bottom 18 serves as the detour water passage section 8, and is formed at several locations on the periphery flange 19. The guide groove 20 is used as the nozzle hole 10.

The material of this product may be stainless steel, cast iron, plastic, etc., or a combination of these may be used.

In the figure, 22 is a water pressure suppressing member having water permeability that suppresses water pressure.

[Effect of idea]

Since the present invention is configured as described above, the groundwater does not communicate with the rectifying gap chamber 6 all at once and is sprayed from the nozzle hole 10, but instead the blocking flange 7 with the detour water flow section 8 provided in multiple stages Since the water passes by detouring through the detour passage formed by the and rectifying gap chamber 6, the water pressure is gradually reduced and the water force is weakened.

In this case, it is necessary to select the number of shutoff flanges 7, the number and size of detour water passage parts 8, and the water flow control valve 1.
By adjusting the amount of water in step 1, it is possible to sprinkle water at the desired amount and pressure, thus providing the optimal snow removal nozzle for snow removal roads that use high-pressure groundwater.

Since the water volume adjustment valve cylinder 3 with the lid 13 is designed to be taken out, the water volume adjustment valve cylinder 3 and the water volume adjustment valve 11
If it is damaged, it can be easily replaced, and the inside of the rectifying gap chamber 6 can be easily cleaned. Also, by removing the water flow control valve cylinder 3 while turning it, it can be replaced at the detour water flow section 8. Since the inner circumferential surface of the rectifying gap chamber 6 is cut, cleaning can be made easier, and this has excellent practical effects.
