Pie sprinkler nozzle

 

(57) Abstract:

Usage: packing is intended to increase the range of the spray pattern rain with reduced intensity. Pie sprinkler nozzle consists of a housing 1 with the water outlet hole 2 in the shape of a truncated cone, rolling into a cylindrical hole with an aspect ratio of length to diameter of 1.0 to 3.0. The presence of a flat area 3 under the water outlet hole 2, followed by a deflector with a width to length ratio of 0.4 to 1.2 forms a laminar flow. The deflector has a shape duchatelet tramplingamateur curved surface with a crest 4, ascending at an angle = 20 - 30oto the horizon. Two lateral descending surface 5 to smoothly pass through curved curves in ascending lateral surface 8, and at the end of the ridge - plane 9, the ascending angle = 40 - 60oto the horizon. When passing through the vent stream gains haste and at a meeting with the air is broken up into small drops. 3 Il.

The invention relates to agriculture, namely, to designs korotkostrizhenih pie sprinkler nozzles.

Known sprinkler nozzle, comprising full housing with connecting thread, the water outlet overstayed is the uneven distribution of precipitation on irrigated surface due to the occurrence of rupture of the spray of the rain.

Closest to the proposed technical solution is the sprinkler nozzle, comprising full housing with connecting thread, the water outlet hole and the flat ground below him, followed by a deflector that is different from the analogue to the fact that its deflector is made in the form of a ridge duchatelet surface extending in a horizontal plane when removed from the hole, the upper end of which moves in a plane, the side edges of the baffle are raised relative to the plane, forming trompenaars edge, and the relationship of the diameter of the water outlet holes, length duchatelier ridge width tramplingamateur edges, the length of the baffle to the length of the flat area, respectively, are located within: 0,3 - 2,0; 4,0 - 6,0; 0,4 - 0,6; 5,5 - 7,5, and the ratio of the width of the deflector to its length is equal to 1.3 - 1.5.with. N 1161052, A 01 CL M 7/00, 15.06.85).

The disadvantage of this nozzle is the lack of range of the spray of rain and its greater intensity.

The aim of the invention is to increase the distance of the spray of rain and decreasing its intensity.

This objective is achieved in that the water outlet hole of the housing in the direction of flow of water made in the form of the data hole, forming laminarinase flow, with the ratio of its length to diameter in the range of 1.0 to 3.0, and the ratio of the width of the deflector to its length in the range of 0.4 to 1.2, while the angle between the line of the ridge vent and a plane passing through the space under the water outlet hole is located within 20 - 35oand the angle between the tangent to the plane of the upper end portion of the deflector and the same plane passing through the space under the water outlet hole is in the range of 40 - 60o.

In Fig. 1 shows a sector of the sprinkler nozzle, General side view of Fig. 2 is a view of the nozzle from the top, with a section along the centerline of the housing; Fig. 3 - deflector in the section along a-a of Fig. 1.

Pie sprinkler nozzle consists of a body 1, for example on the outside in the form of a polyhedron with connection thread, but from the inside with the water outlet hole 2 in the shape of a truncated cone tapering in the direction of flow of water passing into the cylindrical calibrated on a water discharge hole forming laminarinase flow, as well as a flat area 3, followed by a deflector, which is in the form duchatelet tramplingamateur curved surface with a vertical plane passing h pass smoothly, on curved curves in ascending lateral surface 8, and at the end of the ridge, at point 7, in the ascending surface 9.

In order to harden the weakest joints of the vent housing, for example, in the manufacture of the nozzle of the plastic molding by extrusion, it has two lateral tide 10, further connecting one baffle to the enclosure.

The nozzle has the following letter designations of its parameters: the diameter of the cylindrical holes - d0its length l0; length of the area 3 - l1; crest length 4, from point 6 to point 7 - l2x plane 9 - l3; the width of the baffle - B, its length from the point 6 to the end of the width of the plane 9 - l; the angle formed by the line 6 - 7 the top of the ridge 4 and the horizontal plane passing through the space of 3 ; the angle formed by a tangent drawn through the plane 9 with the horizontal plane passing through the space 3 - .

In accordance with letter designations, the nozzle has the following correlation of parameters: d0/l1= 0,3 - 2,0; l2/l1= 4,0 - 6,0; l3/l1= 0,4 - 0,6 l/l1= 5,5 - 7,5; l0/d0= 1,0 - 3,0; B/l = 0.4 - 1.2 and outside corners: = 20 - 30o; = 40 - 60o.

The nozzle is some hole 2, hits in duhallow ridge surface 4, 5, escapes with her curved surfaces of the depressions, rises on the lateral surface 8 and the front surface 9, with which a high speed is reset to the air. In the air water to break up into droplets of rain and at an angle to the irrigated surface rain evenly deposited on the front and the length of the seizure.

The nozzle can be successfully used, for example, as a device that removes water from the cylinder drive wheels trucks multisupport sprinkling machines type "Frigate", and also as an attachment to the garden hose for watering them by way of sprinkling manually.

Pie sprinkler nozzle comprising a hollow body in the shape of a polyhedron with connection thread, the water outlet hole flat pad under it, followed by a deflector is made in the form duchatelet ridge surface, extending at a distance from the hole and the upper end portion of the ridge which, as a side, pass into the curved surface, rising around the perimeter edges of the vent, forming ramps with relations diameter moduleusage holes, length duchatelier ridge width tramplingamateur CROs is tives such as those what, with the aim of increasing the range of spray and rain reduce its intensity, the water outlet hole in the direction of flow of water is made in the shape of a truncated cone, tapering towards the exit and rolling in a calibrated cylindrical bore with respect to its length to diameter in the range from 1 to 3, the ratio of the width of the deflector to its length in the range of 0.4 to 1.2, while the angle between the line of the ridge vent and the plane passing through the area below the outlet is in the range of 20 to 30oand the angle between the tangent to the plane of the upper end portion of the deflector and the same plane passing through the area below the outlet is in the range of 40 to 60o.
