An end of the high-pressure water cavity is provided with an inner nozzle. The outer shell is inside provided with a low-pressure water cavity outside the high-pressure water cavity. The low-pressure water cavity is communicated with a lower-pressure water inlet. Inside the outer shell, the front end of the low-pressure water cavity is provided with a mixing cavity communicated with the low-pressure water cavity. The mixing cavity is communicated with the high-pressure water cavity through the inner nozzle installed in an end part of the high-pressure water cavity. The inner nozzle in the high-pressure water cavity sprays water into the mixing cavity. The mixing cavity is communicated with a cavitation jet flow lead pipe communicated with the outer nozzle.

Description
technical field:
The utility model relates to shower nozzle, is mainly a kind of cavitation shower nozzle that is applicable to cavitation jet.
background technology:
Cavitation jet is that solid jet is modulated into a kind of novel jet flow with strong pressure oscillation and high cavitation threshold energy power, be mainly used on the cleaning technique of hull or pipeline, thereby coordinate cavitation jet need to have special-purpose cavitation shower nozzle, in order to improve jeting effect.
utility model content:
Technical problem to be solved in the utility model is to provide a kind of cavitation shower nozzle that is applicable to cavitation jet, and its structure is ingenious, is provided with the hybrid chamber of High-Pressure Water and low pressure water flow, improves water flow jet effect, easy for installation.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A cavitation shower nozzle that is applicable to cavitation jet, comprises shell body, and shell body is provided with outer nozzle on one end, it is characterized in that: in described shell body, be provided with high-pressure water chamber, be communicated with water under high pressure water inlet on high-pressure water chamber, one end of high-pressure water chamber is provided with inner nozzle; The inherent high-pressure water chamber of described shell body is provided with low-pressure water chamber outward, on low pressure water cavity, be communicated with low-pressure water water inlet, the front end of the inherent low pressure water cavity of described shell body is provided with the hybrid chamber being communicated with low pressure water cavity, the inner nozzle that described hybrid chamber is installed by high-pressure water chamber end is communicated with high-pressure water chamber, and the inner nozzle on described high-pressure water chamber sprays in hybrid chamber; Described hybrid chamber is communicated with a cavitation jet conduit, and described cavitation jet conduit is communicated with outer nozzle.
The tapered structure of described outer nozzle.
At normal temperatures and pressures, fluid molecule effusion liquid surface and become the process of gas molecule, is called " vaporization ".If it is constant to maintain water temperature, the pressure of the water surface is reduced to after certain critical value, the very little bubble that water body inside was contained originally (common name gas core) will expand rapidly, form the obvious bubble that contains steam or other gases in water, and this phenomenon is called " cavitation ".Cavitation forms hole, cavity or cavity in water.The regional area that liquid stream is flowed through, if pressure during lower than certain critical value, also can there is cavitation in liquid.At the liquid of low-pressure area cavitation, carrying a large amount of cavitys and forming " two phase flow " motion, thereby destroying the continuity in liquid macroscopic view, the cavity that current are being carried under one's arms is when the higher region of the downstream pressure of flowing through, and cavity will be crumbled and fall.Therefore, cavitation phenomenon comprise cavity generation, grow and crumble and fall.Cavitation jet is transient state stream theory and the marine acoustics principle of utilizing microvariations ripple to propagate at piping, solid jet is modulated into a kind of novel jet flow with strong pressure oscillation and high cavitation threshold energy power, and cavitation effect adopts self-excited oscillation pulsed water jet to occur conventionally.It is reported, in jet flow cavitation process, more than the microjet speed that the moment of crumbling and fall in hole produces can reach 70-180 m/s, the temperature of 5000 K, the pressure of 140-170MPa, clean surface is subject to microjet number of shocks and is about 100 1 1000 times/s..These conditions are enough to make organic matter that chemical bond rupture, water burning, pyrolytic or radical reaction occur in cavitation bubble, utilize these conditions can be by cavitation jet for cleaning field and other field.When the cavity of vacillating in water constantly produces, grows, breaks, the surge of cavity collapse is constantly applied to cleans on wall, like this, the percussion of microjet will be as hammering the continuous cleaning wall that hitting.Wherein strong percussion will directly be destroyed and clean wall formation pit, and weak impulsive force repeated action can cause the fatigue rupture of wall dirt, it is broken and come off and take away with current.Cavitation effect produces different frequency vibrations in addition, by liquid, is reached dirt and is cleaned wall.Because dirt and cleaning wall are that different materials forms, their intrinsic frequency is also different.For this reason, excite dirt and clean wall with different frequency vibrations, broken dirt and be adsorbed on the bonding force cleaning on wall, make it to become more loose and be easy to remove.Cavitation jet is compared with solid jet, and the surge pressure of jet has improved 1.7 times; Erosion volume has improved 1.5-2.0 doubly; Effectively range has improved 2-4 doubly.If both cleaning performances are the same, the energy that obvious cavitation jet consumes is lower than solid jet, has obtained the energy-conservation result of expection.
The utility model has the advantages that:
The utility model structure is ingenious, is provided with the hybrid chamber of High-Pressure Water and low pressure water flow, improves water flow jet effect, easy for installation.
