Detailed Implementation

[0015] This utility model embodiment provides an ultra-high pressure cavitation cleaning head.

[0016] Example 1, please refer to Figure 1 , Figure 2 and Figure 3 It includes a gas valve 3, a needle valve assembly 5 at the bottom of the gas valve 3, a high pressure rod 7 at the bottom of the needle valve assembly 5, and a fixing block 4 and a cutting head tee 6 on one side of the needle valve assembly 5. A cavitation mixing chamber gem seat 1 is installed at the bottom of the high pressure rod 7. A cavitation mixing chamber sand tube seat 2 is installed at the bottom of the cavitation mixing chamber gem seat 1. A sand tube 11 is installed at the bottom of the cavitation mixing chamber sand tube seat 2. Specifically, the cavitation mixing chamber gemstone holder 1 is used to install gemstones and form a cavitation chamber; the cavitation mixing chamber sand pipe holder 2 is used to install sand pipe 11 and form a cavitation chamber; the air valve 3 is used to control the opening or closing of high-pressure water; the fixing block 4 is used to fix and connect the high-pressure pipe and input high-pressure water through the high-pressure pipe; the needle valve assembly 5 cooperates with the air valve 3 to open and close the high-pressure water, and the needle in the needle valve assembly 5 cooperates with the center hole in the valve gasket to open and close the high-pressure water; the high-pressure rod 7 is used to connect the needle valve, the mixing chamber and the gemstone.

[0017] Please see Figure 1 and Figure 2 The cavitation mixing cavity gemstone seat 1 and the cavitation mixing cavity sand tube seat 2 are combined to form the cavitation mixing cavity; Specifically, a tapered hard seal is used between the cavitation mixing chamber gemstone seat 1 and the cavitation mixing chamber sand tube seat 2 to ensure its sealing performance.

[0018] Please see Figure 1 A locking nut 9 and a sand pipe clamping sleeve 10 are sequentially arranged on the outside of the sand pipe 11. The locking nut 9 is located between the sand pipe clamping sleeve 10 and the cavitation mixing chamber sand pipe seat 2. Specifically, the locking nut 9 is used to fix the sand pipe 11; the sand pipe clamping sleeve 10 is used to clamp the sand pipe 11, which is composed of nozzles.

[0019] Please see Figure 1 and Figure 2 A gem nozzle 8 is provided between the high-pressure rod 7 and the cavitation mixing chamber gem seat 1; Specifically, the gem nozzle 8 is designed to form a water jet from the ejected high-pressure liquid.

[0020] Please see Figure 1 A booster is installed on one side of the fixed block 4; Specifically, the booster uses 400 MPa, and when the water is pressurized to 400 MPa, a water jet of 120 m / s is formed at point 8 of the 0.3 mm sapphire nozzle. Figure 2 At the location, an almost still water cavity is formed by diversion. When a fast water jet enters the cavity, it promotes the cavitation process. Under the guidance of the high-speed water flow, it is ejected from the 1.02 mm sand pipe 11, forming a water jet with dense bubbles, thus achieving the purpose of cavitation cleaning.

[0021] Please see Figure 1 , Figure 2 and Figure 3 The cavitation mixing chamber gem seat 1 is provided with a water inlet 12 and a water inlet 2 13, and the cavitation mixing chamber gem seat 1 is provided with an adjustable air inlet 14.

[0022] Working principle: When the cylinder is not vented, the valve needle is pressed down, and the tip of the valve needle presses against the valve gasket hole, shutting off the high-pressure water flow. When the cylinder is vented, the valve needle is released, and the high-pressure water flow is activated. When the high-pressure water flows at high speed, it generates negative pressure in the cavitation mixing chamber between the sapphire seat 1 and the sand tube seat 2, drawing in atmospheric pressure water. Guided by the high-speed water flow, the water is ejected from the nozzle, forming a water jet with dense bubbles, achieving the purpose of cavitation cleaning. The adjustable air inlet 14 can adjust the magnitude of the negative pressure, thereby regulating the amount of water drawn in.
