Detailed Description

The invention is described in further detail below with reference to the figures and the embodiments.

The invention discloses an adjustable nozzle which is used on a high-pressure water pipe, and can adjust the spraying state of high-pressure water sprayed during the operation of the high-pressure water pipe.

Referring to fig. 1 and 2, the adjustable nozzle of the present embodiment includes a water pipe 10, an adjusting pipe 20 sleeved on a pipe orifice of the water pipe 10, and a transition joint 30 connected in the adjusting pipe 20 in a threaded manner, wherein the transition joint 30 is in an embedded fit with the pipe orifice of the water pipe 10, and is used for limiting an axial direction of the transition joint 30.

Wherein, the adjusting pipe 20 is arranged on the water pipe 10, and the adjusting pipe 20 is in clearance fit with the water pipe 10, and a clearance is reserved between the adjusting pipe 20 and the water pipe 10. The adjusting pipe 20 of this embodiment is sealed by a sealing packing 40, preferably a rubber O-ring, inserted between the side of the adjusting pipe 10 and the water pipe 10.

In this embodiment, the adjusting pipe 20 is further provided with a plurality of positioning bolts 21 and a plurality of adjusting bolts 22 to match with the pipe wall of the water pipe 10. It should be noted that the adjusting pipe 20 is specifically provided with a threaded hole, and the positioning bolt 21 and the adjusting bolt 22 are connected to the adjusting pipe 20 in a threaded manner so as to be matched with the pipe wall of the water pipe 10. Further, the sealing packing 40 and the adjusting bolt 22 are disposed on both sides of the positioning bolt 21.

Specifically, the adjusting tube 20 is provided with 3 positioning bolts 21 and 3 adjusting bolts 22 in an annular array. The pipe wall of the water pipe 10 is provided with an annular groove 11, and the positioning bolt 21 on the adjusting pipe 20 extends downwards into the annular groove 11 on the pipe wall of the water pipe 10 and is used for limiting the axial direction of the adjusting pipe 20, preferably, the width of the annular groove 11 is larger than the outer diameter of the positioning bolt 21. The adjusting bolt 22 is directly abutted downwards on the pipe wall of the water pipe to limit and fix the adjusting pipe 20 on the water pipe 10.

As can be seen from the above, the transition joint 30 is in an embedded fit with the pipe orifice of the water pipe 10, specifically, in this embodiment, the transition joint 30 is provided with a plurality of bumps 31 on the end portion of one side facing the pipe orifice of the water pipe 10, preferably, 2 bumps 31 are provided in an annular array manner, the pipe orifice of the water pipe 10 is correspondingly provided with a plurality of slots 12, and the slots 12 are in an embedded fit with the bumps 31, in this embodiment, the embedded fit between the slots 12 and the bumps 31 is also in a clearance fit. It should be noted that, in the present embodiment, the transition joint 30 and the pipe orifice of the water pipe 10 are in an embedded fit, and a clamping groove may be formed on the transition joint 30, and a projection is arranged on the pipe orifice of the water pipe 10.

In this embodiment, the end of the transition joint 30 far away from the nozzle of the water pipe 10 is spherical, the end of the adjusting pipe 20 far away from the water pipe 10 is concave spherical, and the outer diameter of the spherical end 32 of the transition joint 30 is equal to the inner diameter of the concave spherical end 23 of the adjusting pipe 20. That is, the spherical end 32 of the transition joint 30 may engage the concave spherical end 23 of the adjustment tube 20.

As can be seen from the above, the high pressure water in the water pipe 10 passes through the transition joint 30 from the nozzle of the water pipe 10, and then is jetted outward from the spherical end 32 of the transition joint 30 toward the concave spherical end 23 of the adjusting pipe 20. Therefore, the high-pressure injection structure of the present embodiment, when used specifically:

referring to fig. 4, when the spraying angle needs to be adjusted, the adjusting bolt 22 (the bolt directly abuts against the outer wall of the water pipe) for adjusting the relative angle according to the direction requirement, and the adjusting pipe 20 slightly swings with the positioning bolt 21 and the annular groove 11 as the fulcrum. At this time, the two spherical surfaces of the concave spherical end 23 of the adjusting tube 20 and the spherical end 32 of the transition joint 30 have a sufficient distance and are not in contact with each other, and the nozzle injection is in a closed state under the action of the concave spherical end 23 of the adjusting tube 20, the injection distance is at a minimum, but the injection force is also in a most concentrated state.

Referring to fig. 3, when the injection distance needs to be increased, the adjusting pipe 20 is radially rotated by taking the positioning bolt 21 and the annular groove 11 as fulcrums, the transition joint 30 is restricted by the clamping groove 12 of the water pipe 10 and does not rotate in the rotating process, but under the action of the internal and external threads of the transition joint 30 and the adjusting pipe 20, the transition joint 30 realizes axial movement (as mentioned above, arbitrary rotation ensures the embedded connection between the bump 31 and the clamping groove 12) to adjust the relative movement between the two spherical surfaces of the concave spherical end 23 of the adjusting pipe 20 and the spherical end 32 of the transition joint 30, the shape of the water column of the injection port is changed while the distance between the two spherical surfaces is changed, and when the inner diameters of the two spherical surfaces are in close-up fit, the injection port is not restricted by the close-up and is in.

Referring to fig. 5, it can be understood that the two adjustment manners are axial adjustment of the adjusting tube 20, and in this embodiment, radial adjustment of the adjusting tube 20 is also possible. Specifically, the adjusting bolt 22 screwed on the adjusting tube 20 is screwed to change the coaxiality between the orifice of the adjusting tube 20 and the water pipe 10, so as to achieve the requirement that the orifice of the adjusting tube 20 is inclined and positioned in the direction in which the orifice is aligned, the maximum adjusting range is limited by the gap between the inner diameter of the adjusting tube 20 and the outer diameter of the water pipe 10, and the processing gap is determined according to the specific adjusting requirement.

In summary, the adjustable nozzle provided by the invention has the advantages that through reasonable structural arrangement, when the adjustable nozzle is used, the axial directions of the concave spherical end part of the adjusting pipe and the concave spherical end part of the transition joint can be adjusted, and the radial direction of the adjusting pipe relative to the water pipe can be adjusted, so that the spraying state of high-pressure water sprayed by the adjustable nozzle during working can be adjusted, the adjustment is convenient, and the use requirement of an industrial field is met.
