JPS586526Y2 - spray nozzle - Google Patents

Description

[Detailed explanation of the invention] This invention creates a water curtain in a fire extinguishing system, etc., and when cooling a tank or preventing a fire, the height and width of the water curtain is changed by changing the nozzle angle and the concentration angle of the spray. This invention relates to a variable nozzle that can arbitrarily change the nozzle.

Normal nozzles are made by changing the hole diameter and shape to provide performance tailored to each purpose.

However, in this case, there is only one nozzle 12, and the height and width of the water curtain created by the water pressure and the nozzle hole diameter are limited.

The present invention eliminates the drawbacks of the conventional method, and by concentrating the pressure water ejected from multiple nozzles at one point, the water curtain can be raised higher with the same pressure, and the nozzle angle and concentration point can be changed. Accordingly, it is an object of the present invention to provide a spray nozzle in which the height and width of the water curtain can be freely changed.

Embodiments of the present invention will be described with reference to the drawings.

Reference numeral 1 denotes a body formed into a Y-shaped cross section, with a pressure water flow port 2 provided at its base, and pressure water discharge ports 3 and 4 branched on both left and right sides of the upper end connected to the pressure water flow port 2. It can be opened.

Backings 5 and 6 are formed at the open ends of the pressure water outlets 3 and 4, respectively, and screws 7 and 8 are formed on the outer peripheral surfaces of the open ends of these pressure water outlets 3 and 4.

9 and 10 are nozzle members having a spherical outer peripheral surface that fit into the backings 5 and 6, and 11 and 12 are tubular parts connected to these nozzles and having a through hole,
Nuts 13 and 14 are engaged with the outer peripheral surfaces of the nozzle members 9 and 10 and screwed onto the screws 7 and 8 on the outer peripheral surfaces of the pressure water discharge ports 3 and 4.

15 is a rod protruding from the center of the upper surface of the body 1;
Adjustment nuts 16 and 17 are screwed onto the screw rod 15 in contact with the upper and lower surfaces of the adjustment ring 18 that is loosely inserted into the screw rod 15, and adjustment nuts 1 and 20 are screwed onto the adjustment ring 18 with one end attached to the adjustment ring 18 with pins 21 and 22, respectively. The other ends are connected to nozzles 9 and 1, respectively.
The connecting rod for adjusting the fountain angle is shown pivoted to the tubular parts 11 and 12 of 0 with pins 23 and 24.

Since the present invention is constructed as described above, pressure water flows from the inlet 2 through the discharge ports 3 and 4 to the nozzle members 9 and 10.
is discharged from the tips of the tubular parts 11 and 12.

and tubular portions 11 and 12 of nozzle members 9 and 10.
The nuts 13 and 14 are connected to the body 1 by selecting and adjusting the angles of the nozzle members 9 and 10 and the concentration point of the discharged water so that the pressurized water discharged from the openings of
By fixing the nozzles 9 and 10 with screws, the discharged water can be continuously formed to form a water curtain having the required height and width. By inserting the adjusting rod 18 and fixing it with the adjusting nuts 16 and 17, the nozzle members 9 and 10 can be installed in a high place such as a building or a fuel tank. It is possible to perform a prescribed spray while preventing the relative position of the spray from changing, and it is extremely effective when used in disaster prevention equipment and the like.
