Embodiment approach

[0028] As an embodiment of the present invention, the nozzle housing 2 is straight cylindrical, one end of the nozzle housing 2 is provided with a high-pressure pipe connection groove 21, and the bottom of the high-pressure pipe connection groove 21 is provided with a nozzle for installing the riser. 1, the nozzle housing 2 has a nozzle 23 that communicates with the riser installation chamber 22 and the outside of the nozzle housing 2; after the riser 1 is installed, the conical shrinkage The outlet channel section 12 communicates with the high-pressure pipe connection groove 21 , and the straight tube channel section 14 communicates with the nozzle 23 . The structure of the sprinkler housing 2 is set in a straight cylinder, which is similar to a conventional linear sprinkler. Therefore, the width of the sprinkler housing 2 is small, and it can be inserted into the cracks between the concrete for demolition; in order to prevent water leakage, install high-pressure Behind the p...

Abstract

The invention relates to a deflection nozzle. The deflection nozzle comprises a nozzle shell and a spraying core. The spraying core is arranged in the nozzle shell. A flow channel is formed in the spraying core. The flow channel comprises a conical necking flow channel section, a corner flow channel section and a straight cylinder flow channel section, wherein the conical necking flow channel section, the corner flow channel section and the straight cylinder flow channel section are sequentially connected, and the small end of the conical necking flow channel section is connected with the corner flow channel section. The deflection nozzle is used for solving the technical problem that existing high-pressure water jet nozzles cannot crush concrete in a narrow space and cannot hit concrete behind steel bars.

Description

technical field [0001] The invention relates to the field of high-pressure water jet crushing, in particular to a deflecting nozzle. Background technique [0002] High-pressure water jet technology refers to the use of high-pressure water jets to remove the deteriorated concrete of concrete structures, so as to facilitate the repair of these building structures, so that they can be transformed and reinforced. The working principle is to pressurize the high-pressure pump and deliver the high-pressure water to the actuator. The actuator ejects high-speed water flow, which acts on the concrete surface. The high-speed water flow penetrates into the micropores on the concrete surface, and the speed is converted into pressure. When the pressure is greater than the concrete When the tensile strength is exceeded, the concrete is broken. Since the surface of the steel bar is dense and there are no micropores, high-pressure water cannot drill in, so the steel bar is not damaged. [...
