Referring to fig. 1 to 5, the present embodiment provides a spray pressure adjusting apparatus, which includes a high pressure pipe 1 for flowing liquid and an adjusting member 2 for adjusting the spray form and pressure of the liquid, wherein one end of the high pressure pipe 1 is provided with a first spray hole 11 for spraying the liquid from the high pressure pipe 1, the adjusting member 2 includes a rotating shaft portion 21 and a shaping portion 22, the rotating shaft portion 21 is disposed at one side of the high pressure pipe 1, the shaping portion 22 is provided with a second spray hole 23 and is not limited to one, and the shaping portion 22 can rotate along the circumferential direction of the rotating shaft portion 21 and/or move along the axial direction through the rotating shaft portion 21 for adjusting the relative position of the second spray hole 23 and the first spray hole 11.
When the invention is used, liquid is sprayed from the first spray hole 11 of the high-pressure pipe 1 to form a liquid high-pressure spray ray, the high-pressure spray liquid sprayed from the first spray hole 11 acts outwards due to the internal force of the high-pressure spray liquid, so that the high-pressure spray liquid is in a divergent shape, and in order to adjust the shape and the pressure of the sprayed high-pressure spray liquid, the adjusting piece 2 is provided with the second spray hole 23 corresponding to the first spray hole 11, so that the liquid is sprayed from the first spray hole 11 and enters the second spray hole 23, the second spray hole 23 can move along the axial direction of the rotating shaft part 21 to adjust the distance from the first spray hole 11 through the rotating shaft part 21, the divergent angle and the spray pressure of the liquid sprayed from the second spray hole 23 can be adjusted, and the second spray hole 23 can also rotate relative to the high-pressure pipe 1 through the rotating shaft part 21 to change the relative position of the axis of the second spray hole 23, so that the liquid which diverges after being sprayed from the first spray hole 11 is hit at different positions of the first spray hole 11 to reflect the liquid with different divergent angles and the spray pressures from the second spray hole 23.
In addition, since the second nozzle hole 23 of the present invention is not limited to one, when there are a plurality of second nozzle holes 23, the shaping portion 22 is rotated in the circumferential direction and/or moved in the axial direction of the rotation shaft portion 21, so that different second nozzle holes 23 correspond to the first nozzle holes 11, thereby changing the ejection pressure and angle of the ejected liquid.
Referring to fig. 3, in the present embodiment, the second nozzle hole 23 includes a diverging portion 231, and the axial cross-section of the diverging portion 231 is in a horn shape or a bidirectional horn shape, and in the present embodiment, the diverging portion 231 is in a horn shape, which helps to expand the divergence angle of the liquid emitted from the second nozzle hole 23 and quickly reduce the emission pressure of the liquid.
Specifically, the included angle R between the inner side wall of the diverging portion 231 and the axis of the second nozzle 23 is 0-80 °, in this embodiment, the included angle R is 15 °, so that when the liquid ejected from the first nozzle 11 enters the second nozzle 23 and is ejected from the second nozzle 23, the diverging portion has a good diverging angle, and is suitable for the liquid action area required by most working scenarios.
Referring to fig. 4, further, the second nozzle hole 23 includes a reflecting portion 232, so that the liquid ejected from the first nozzle hole 11 is reflected on the inner sidewall of the reflecting portion 232, on one hand, the ejection path of the liquid is changed, so as to change the divergence angle of the whole liquid ejected from the second nozzle hole 23, on the other hand, the ejection pressure of the liquid is changed by the impact, specifically, the inner sidewall of the reflecting portion 232 extends along the axial direction of the second nozzle hole 23, so that the liquid path ejected from the first nozzle hole 11 forms a certain included angle with the inner sidewall of the second nozzle hole 23, thereby increasing the quantity of the liquid reflected by the inner sidewall of the second nozzle hole 23, and further increasing the capability of reducing the ejection pressure of the liquid;
Referring to fig. 5, in which the rotation of the rotating shaft 21 changes the relative positions of the first nozzle hole 11 and the second nozzle hole 23, so that the first nozzle hole 11 and the second nozzle hole 23 are eccentrically arranged, and the liquid ejected from the first nozzle hole 11 impinges on different positions of the reflecting portion 232 of the second nozzle hole 23, so as to realize more various liquid ejecting modes of the second nozzle hole 23, preferably, the rotating angle of the rotating shaft 21 in this embodiment is 0 to 360 °.
Referring to fig. 2, wherein the diameter D of the reflecting portion 232 is 0.01 to 10mm, the liquid ejected from the first nozzle hole 11 is limited to 0.01 to 10mm when directly entering the second nozzle hole 23 based on the range of the diameter D, thereby controlling the divergence angle and pressure formed after the liquid is ejected from the second nozzle hole 23.
Further, the distance L between the end of the second nozzle 23 near the first nozzle 11 and the first nozzle 11 is 0-50 mm, the second nozzle 23 moves axially relative to the high pressure tube 1 through the rotating shaft portion 21, the moving distance L is 0-50 mm, when the liquid is ejected from the first nozzle 11 by adjusting the distance between the second nozzle 23 and the first nozzle 11, the divergence angle of the ejected liquid increases with distance from the first nozzle 11, that is, with different distances between the second nozzle 23 and the first nozzle 11, the divergence angle of the liquid ejected from the first nozzle 11 into the second nozzle 23 is different, so that the divergence angle and the ejection pressure of the liquid ejected from the second nozzle 23 are changed, and based on the distance L, the divergence angle and the ejection pressure of the liquid ejected from the second nozzle 23 in this embodiment are suitable for most working environments.
Referring to fig. 1 and 2, in order to improve the stability of the installation of the adjusting member 2 and the high-pressure tube 1, the embodiment further includes a supporting frame 3, where the supporting frame 3 is provided with a first sleeve hole 31 and a second sleeve hole 32, respectively, so that the high-pressure tube 1 is sleeved and fixed in the first sleeve hole 31, and the adjusting member 2 is sleeved and fixed in the second sleeve hole 32, which is helpful to fix the radial distance between the adjusting member 2 and the high-pressure tube 1, and improve the stability of adjusting the relative positions of the first spray hole 11 and the second spray hole 23.
