のである。 As described above, the nozzle according to the present invention has two nozzle discharge ports 8 arranged in the front and back direction in the nozzle body 1.
V-shaped grooves 10 and 1 with inclined V-shaped grooves 10 and 1 having discharge ports 8b and 9b formed in opposite left and right directions;
1, the air/water mixture that has flowed from the inflow channel 7 into the branch channels 8 and 9 is sprayed in a fan shape in one direction (to the left) from one of the discharge ports 8b. , a fan-shaped injection is performed in the other direction (to the right) from the other discharge port 9b. That is, as shown in FIG. 8, the jet is ejected from one outlet 8b at a spray angle θ1 that is offset to the left of the central axis l1 of the nozzle body 1 , and from the other outlet 9b to the right side of the axis l1 . The injection is performed at a spray angle θ 2 that is offset toward the center of the injection area, and there is a region S 1 in the center of the injection region that appears to partially overlap, but the discharge ports 8b and 9b
The total injection area S 2 is a wide range including the injection area from . Also, the spray amount Q indicated by the vertical diagonal line Y in Fig. 8
For example, when the height H of the nozzle body 1 is 160 mm, the liquid volume L is 10.4 l/min, and the gas-liquid ratio R is 48.5, the central part where the spray volume Q from each outlet 8b and 9b is small is Since the spray amounts Q from the discharge ports 8b and 9b are combined, the amount is approximately the same as that on both sides where the spray amount is large, and a more even amount of the air-water mixture is sprayed over the entire spray range. Furthermore, as shown in Fig. 9, on both sides of the spray range S, the spray is sprayed in an area of W width from each discharge port 8b, 9b, but in the central part, it is sprayed only in a width narrower than W width from each discharge port. However, since the spraying from both outlets is lined up in the width direction, a wider W width is also sprayed, and the pattern area is approximately the same as the approximately rectangular area of the W width. Can be covered evenly. Furthermore, the respective spray areas injected from both discharge ports 8b and 9b are
As shown in the figure, since they are separated without overlapping, the mist particles are separated and fine, especially right below the discharge ports 8b and 9b, and since the respective particles do not overlap, the cooling condition is This is something that is well done.

Furthermore, since the spraying is performed in the same range symmetrically with respect to the central axis l1 of the nozzle, it is sufficient to arrange the nozzle axis l1 perpendicular to the object surface above the center of the object surface. Since surfaces 2C and 2D for indicating directionality are provided above the upper nozzle, the direction of the nozzle can be set extremely easily during use.

The atomized mist is sprayed as a substantially uniform atomized mist within a certain range in front of the top surface of the nozzle body,
Two fan-shaped nozzles with a spray angle of θ on one side are arranged side by side in a single nozzle body, and the fan-shaped jets are made in opposite directions, and the center parts overlap, so that it can be used from extremely close distances. A fine mist can be sprayed over a wide range on the surface of the object with a uniform spray amount and a uniform area. Furthermore, since two nozzle discharge ports are provided in the nozzle body which is structurally compact, it is possible to spray over a wide range without taking up much space.

As shown in Figs. 26 and 27, two fan-shaped nozzles with a spray angle of θ on one side are arranged side by side in the same injection hole, and by overlapping a part of the central part, the amount of spray can be reduced. Looking at Q, for example, the nozzle body 1″
When the height H = 160 mm, the liquid volume L = 11.3 l/min, and the air-liquid ratio R = 43.6, a mist of air/water mixture is evenly spread over a wide range of the target surface from a very close distance. Furthermore, a substantially uniform width (W) can be obtained in terms of pattern area.

うにしたことを特徴とするスプレーノズル。 The inlet passage into which the air-water mixture is introduced is formed by having at least one or more holes extending from the bottom opening of the columnar nozzle body into the inside of the nozzle body along the axis of the nozzle body to near the top surface of the nozzle body. The nozzle body is formed as a linear injection hole at the bottom, and is provided in the vicinity of the intersection except for the intersection with the axis of the injection hole on the top surface of the nozzle body, which is formed as one plane approximately perpendicular to the axis of the injection hole. A notched sloped surface is formed from the ridge line to the opposite side of the nozzle body from the top surface to the bottom surface, corresponding to each of the injection holes, and further on each of the sloped surfaces. A concave groove having a V-shaped cross section with a constant depth running longitudinally along an inclined line approximately perpendicular to the dividing ridge line is formed at a position on at least one side extending at a certain distance from the axis of the corresponding injection hole. The bottom of the groove and the top of the injection hole communicate with each other to open a discharge port, so that the air-water mixture introduced under high pressure into the inlet channel opened at the bottom of the nozzle body is injected into the injection hole. A spray nozzle characterized in that a substantially uniform atomized mist is sprayed within a certain range from the discharge port at the top of the hole through the groove to the front of the top surface of the nozzle body.
