Problems solved by technology

There are filtering and softening devices in the high-pressure water jet equipment, but these impurities cannot be completely removed, and there are also free metal debris inside the high-pressure pipeline. Under the washing of ultra-high pressure water, the edge of the gemstone hole will slowly passivate or even shatter. cracks, resulting in a drop in jet quality, and then failure

Embodiment 1

[0045] See figure 1 , image 3 , Figure 4 with Figure 5 , An ultra-high-pressure liquid jet diamond nozzle, comprising a diamond sheet 1, a metal nanopowder layer 2, a metal gland 3, and a metal casing 4, the metal casing 4 is provided with a built-in cavity, and the metal gland 3 is covered Fixed at the bottom of the built-in cavity, the built-in cavity is filled with metal nanopowder and forms a metal nanopowder layer 2. The metal nanopowder layer 2 is provided with a diamond sheet 1, which is set on a metal The central axis of the shell 4 is located in contact with the inner wall of the inner cavity of the metal shell 4, the metal nano powder layer 2 tightly wraps the diamond sheet 1 and the metal shell 4 is integrated.

[0046] The top of the metal shell 4 is provided with an upper opening 5, the metal gland 3 is provided with a lower opening 6, the diamond sheet 1 is provided with a nozzle through hole 7, and the bottom of the upper opening 5 The cone, the top cone of the ...

Embodiment 2

[0053] See figure 2 , image 3 , Image 6 with Figure 7 This embodiment is used as a further implementation structure of the first embodiment. On the basis of this, the diamond sheet 1 is arranged at the central axis position of the metal shell 4 and completely wrapped in the inner cavity of the metal nano powder layer 2. The bottom cone tip of the upper opening 5 extends to the inner cavity of the metal nano powder layer 2, and a tapered opening is formed on the top of the metal nano powder layer 2. The diamond sheet 1 is not in contact with the metal shell 4 and is completely wrapped in the inner cavity of the metal nano powder layer 2.

[0054] Preferably, see Figure 8-13 , The illustrations are all diamonds with different hole types and structures after being processed to meet the needs of different types of processing operations.

Abstract

The invention relates to a nozzle technology, in particular to a diamond nozzle of an ultra-high pressure liquid jet and a manufacturing method of the diamond nozzle. The diamond nozzle comprises a diamond sheet, a metal nano-powder layer, a metal backup shoe and a metal shell, the metal shell is provided with a built-in cavity, the cavity is filled with metal nano-powder and forms a metal nano powder layer, the metal nano powder layer is internally provided with the diamond sheet, the diamond sheet is arranged at the position of a central axis of the cavity of the metal shell, tightly wrappedby the metal nano-powder and integrated with the metal shell, the top of the metal shell is provided with an upper formed opening, the metal backup shoe is provided with a lower formed opening, the diamond sheet is internally provided with a nozzle through hole in a penetrating mode, and communicates with the upper formed opening and the lower formed opening. According to the diamond nozzle, diamond is adopted as a core material, the hardness and flow coefficient are high, the diamond is installed in a cutting head and a spraying head of fluid equipment, the jet effect is better, crack and passivation of an orifice cannot be produced in the use process, and the service life of the nozzle is far longer than that of other materials.

Description

Technical field [0001] The invention relates to nozzle technology, in particular to a diamond nozzle with ultra-high pressure liquid jet and a manufacturing method thereof. Background technique [0002] The nozzle is an energy conversion element, which converts the pressure energy of the water medium into the kinetic energy of the water jet, and then shoots out in the form of a high-speed water jet, which can clean, crush and cut the material. The pressure range of the high-pressure water jet is very wide, so there are many types of nozzle materials. The materials used to make nozzles on the market mainly include stainless steel, high-quality carbon steel, tool steel, cemented carbide, ceramics, artificial gems, and diamonds. The higher the output pressure of the pump, the higher the hardness of its material handling. [0003] The most commonly used ultra-high pressure nozzle material is artificial gemstone (corundum), which has a hardness of 9 on the Mohs scale. However, with t...
