Abstract

The utility model relates to a shock energy transducer which comprises a cylindrical mixing chamber. A fluid inlet is arranged at the inlet end of the mixing chamber, a fluid outlet is arranged at the outlet end, a fluid suction inlet is arranged in the middle, and the tail end of the fluid inlet is designed into a tapered nozzle; a tubular diffuser is installed at the rear part of the fluid suction inlet in the mixing chamber; and an outlet of the diffuser is communicated with the fluid outlet. The diffuser is divided into three sections, the front section is taper-shaped, the middle section adopts a straight tube, and the rear section is diverged. The mixing chamber is designed into a cylinder shape. The shock energy transducer adopts the shock wave generated when the pressure of the water is reduced in an accelerated way, and compresses vaporized gas to ensure that the gas is fluidized but is not expanded and to ensure the ejected fluid to smoothly enter into the mixing chamber to be ejected. Both low-temperature water and high-temperature water can be used as ejection power, thereby the ejection power source and the ejection range are expanded.

Description

The shock wave transducer

Technical field

The utility model relates to a kind of lead-jetting device, a kind of specifically device that utilizes other fluids of hot water injection.

Background technique

Water jet technology in the past all is that water temperature rising ejector capacity reduces with other fluids of low temperature water injection.When the temperature rising reaches water vapor with the pressure that produces, promptly can not realize injection.

The model utility content

For realizing that the utility model provides a kind of shock wave transducer with other fluids of high-temperature water injection, adopt this device can realize with other fluids of high-temperature water injection.

The utility model realizes that the technological scheme of above-mentioned purpose is:

A kind of shock wave transducer comprises the tubular mixing chamber, and the entry end of this mixing chamber is established fluid inlet, and outlet end is established fluid output, and the fluid suction inlet is established at the middle part, it is characterized in that:

The tip designs of described fluid inlet becomes the gradually-reducing shape nozzle;

The tubulose Diffuser is installed at the place, rear that is positioned at described fluid suction inlet in the described mixing chamber, and the outlet of this Diffuser is communicated with described fluid output.

In implementing measure of the present utility model:

Described Diffuser is divided into three sections, and leading portion is a convergent shape, and the stage casing is a straight tube, and back segment is a gradually expanding shape.

Described mixing chamber is designed to cylindric.

The diameter of described mixing chamber is 10-15 a times of described jet expansion bore.

The shock wave that the utility model produces when utilizing water to quicken decompression, the compressed boil-off gas makes it liquefaction and does not expand, and guarantees that driven fluid enters mixing chamber smoothly by injection.Not only low temperature water can be as injection power, and high-temperature water also can be done injection power, thereby enlarged injection power source and injection scope.

Description of drawings:

Fig. 1 is a structure principle chart of the present utility model.

Embodiment:

Below in conjunction with accompanying drawing the utility model is elaborated.

The utility model is a kind of shock wave transducer, comprises cylindric mixing chamber 1, and the entry end of this mixing chamber 1 is established fluid inlet 2, and outlet end is established fluid output 6, and fluid suction inlet 5 is established at the middle part, and the end 3 of fluid inlet 2 is designed to the gradually-reducing shape nozzle; Tubulose Diffuser 4 is installed at the place, rear that is positioned at fluid suction inlet 2 in the mixing chamber 1, and the outlet of this Diffuser 4 is communicated with fluid output 6.

Wherein: Diffuser 4 is divided into three sections, and leading portion is a convergent shape, and the stage casing is a straight tube, and back segment is a gradually expanding shape.

Mixing chamber 1 is the essential condition that produces shock wave, according to the temperature and pressure of injection water, its diameter be fluid inlet 2 end 3 the jet expansion bore 10-15 doubly.Hot water enters mixing chamber 1 through intake pipe 2 and nozzle 3, and in negative throat noz(zle) section step-down speedup, pressure can be converted into the speed energy, and the pressure of mixing chamber 1 is reduced.The vaporization of hot water decompression rear section produces pressure shock wave but the structure of mixing chamber 1 is a diameter when designing to such an extent that make high speed hot water by mixing chamber, and the steam of this shock wave compressed boil-off makes it become water again, thereby keeps the negative pressure of mixing chamber 1.The pressure of driven fluid is higher than the pressure of mixing chamber, and pressure official post driven fluid enters mixing chamber 1 and mixes with high speed hot water through fluid suction inlet 5.Fluid-mixing enters Diffuser 4, can change into the pressure energy to speed again, fluid-mixing is boosted after fluid output 6 flows out mixing chamber, finishes injection.
