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, but after many years of use, the water level gradually drops and becomes low-pressure water, which weakens the force of groundwater and makes it difficult to determine how much water there is. Even when the control valve was opened, the water pressure was weak, so water was not evenly sprayed all the way to the end.

[Problem to be solved by the device] The present device has solved such problems, and even if the water is high pressure, it can be increased to the desired water pressure and the desired water volume,
The technical challenge is to provide a snow melting sprinkler nozzle that can spray water at the desired water pressure.

[Means to solve the problem]

A water flow control valve cylinder 3 is installed vertically at the center of the top 2 of the water pipe connection cylinder 1, and the lower end 4 of this water flow control valve cylinder 3 is fitted 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 flow regulating valve cylinder 3 above the partition wall 5 and the inner periphery of the water pipe connection pipe 1, and a blocking collar 7 is provided on the outer periphery of the water flow regulating valve cylinder 3.
A spiral flow channel 8 is formed between the blocking flange 7 and a communication hole 9 communicating with the rectifying gap chamber 6 is bored in the water flow control valve cylinder 3. This relates to a water spray nozzle for snow melting in which nozzle holes 10 communicating with a rectification gap chamber 6 are bored at several locations on the top part 2 of the vehicle.

In addition, the screw hole 12 provided at the center of the top portion 2 of the water pipe connection tube 1 is inserted into the upper end screw portion 1 of the water flow control valve tube 3.
3, and fit the lower end 4 of this water flow control valve cylinder 3 into the partition wall 5 provided in the middle of the inner hole of the water pipe connection pipe 1, and connect the outer periphery of the water flow control valve cylinder 3 above this partition wall 5 with the water flow control valve cylinder 3. A rectifying gap chamber 6 is formed between the inner periphery of the water pipe connection cylinder 1, and a shutoff flange 7 is formed on the outer periphery of the water flow control valve cylinder 3.
A spiral flow channel 8 is formed between the blocking flange 7 and a communication hole 9 communicating with the rectifying gap chamber 6 is bored in the water flow control valve cylinder 3. This relates to a water spray nozzle for snow melting in which nozzle holes 10 communicating with a rectification gap chamber 6 are bored at several locations on the top part 2 of the vehicle.

The present invention also relates to a water sprinkler nozzle for snow removal, in which a ceiling lid 15 is provided at the upper end of the water flow control valve cylinder 3, and the roof lid 15 is used as the ceiling part 2 of the water pipe connection cylinder 1.

[Effect]

When groundwater is fed to the riser pipe 14, the fed groundwater is discharged from the communication hole 9 and introduced into the rectification gap chamber 6.

Then, the groundwater flows along the spiral flow channel 8 formed by the blocking flange 7 while swirling around and around, so that the water force gradually becomes stronger and is sent upward.

Then, the groundwater that is vigorously sent out is sprayed onto the road surface from the nozzle hole 10.

That is, since the groundwater passes through the spiral flow channel 8 formed by the blocking flange 7 and the rectifying gap chamber 6, the low pressure water gradually changes to high water pressure due to the swirling phenomenon, thereby making it possible to perform high pressure water sprinkling.

In this case, the longer the distance of the spiral flow channel 8, the stronger the water pressure, that is, the water force.

Note that the amount of water can be adjusted by adjusting the degree of opening of the communication hole 9.

[Effect of idea]

Since the present invention is configured as described above, the groundwater does not pass through the rectification gap chamber all at once and is sprayed from the nozzle hole, but instead uses a spiral flow channel formed by the blocking flange and the rectification gap chamber. As it passes by while turning, the water pressure gradually increases due to the swirling phenomenon, and the water force becomes stronger.

In this case, by increasing the distance of the spiral flow channel, increasing the spiral angle, or adjusting the water volume with a water flow control valve, the desired amount of water and water pressure can be sprinkled on the snow removal road using low-pressure groundwater. We will provide the best snow removal nozzle for.
