Abstract

The utility model relates to a nozzle in the jetting technology of high-pressure water. A cone bundle opening at the front part of an inner cavity of a nozzle body and the combining part of the back part are provided with fluid inner holes which are smoothly connected by a circular arc curve. An annular wall of an inner opening of the cone bundle opening at the front part of the nozzle body is provided with a plurality of surrounding inclined holes which are uniformly distributed towards the inclined front direction, and the design of the inclined holes can select different angles, different hole diameters and different numbers according to scale layers with different structures and different hardness. The weak links of the scale layers and the combining parts of the end surfaces of the scale layers are intensively shot by matching the jetting of high-pressure water, and the layered scale is shot off in high efficient and quick mode.

Description

Penetrate nozzle tiltedly

The utility model relates to a kind of nozzle in the high pressure water jet.High pressure water jet is by special high pressure lift device, and with common water sources such as running water, supercharging is hundreds of to thousands of atmospheric pressures.Current after this supercharging pass through spray-hole tiny in the special shower nozzle again, produce high high-speed water jet, and the energy height that sends is concentrated, and this energy can produce the effect of cutting.Utilize this characteristics, it is dirty to can be used to remove rust, foulant, adhesive and tamper in oxide and the removing pipeline.According to relevant document introduction both at home and abroad, the nozzle kind is a lot, and structure is different, for emphasizing the advancement function of nozzle, spray orifice all be designed to oblique rear to.The shortcoming of penetrating the nozzle maximum tiltedly is to make full use of energy.

The purpose of this utility model is to penetrate nozzle before adopting tiltedly, makes high-pressure hydraulic directly act on dirt layer end face, impacts dirt layer joint portion, improves scale removal efficient.

The technical scheme of penetrating nozzle before the utility model is oblique is that being provided with inner chamber anterior in the nozzle body is the cone-beam mouth, and sprinkler body inner chamber rear portion is a circular curve with anterior connecting.It is characterized in that the anterior circular cone ring wall of inner chamber has several peripheral uniform spray orifices, spray orifice is to oblique the place ahead, and center line and sprinkler body axis have certain included angle.For making ejection water jet scattering minimum, the spray orifice exit there is a plane perpendicular to the orifice center line.

During work, water under high pressure penetrates through tiny spray orifice by the nozzle inner chamber, and pressure can be converted into high-velocity flow, and its flow velocity is near velocity of sound, and its energy can be concentrated and act on working face.This nozzle is when removing dirty thing, and the jet of spray-hole mainly is the layering joint portion end face to the shooting layer of scale to oblique the place ahead, attacks its dirt layer weak link, increases work efficiency, and hits layer dirt as early as possible.When real work, according to different structure, the dirt layer of different hardness adopts different nozzles, the perforation angle of nozzle, and the spray orifice aperture, nozzle hole number, the pressure of water under high pressure all can design by seriation.

The beneficial effect of penetrating nozzle tiltedly mainly is that high-pressure water jet directly acts on dirt layer end face.To removing the dirty thing of different structure different hardness, can both play better effects.Foulant mainly is a stratiform in the pipeline, and when removing dirty thing, the jet line of spray-hole forms an angle with the dirty end face of layer, the energy of jet, joint portion of each dirt layer of concentrated fire, and the joint portion is the weak link of layer dirt between the dirt layer, so jet can hit a layer dirt smoothly and reaches the quick descaling purpose.Be and shirk the heavy work and choose the light, attack weak link, art is good for strength.

Example: facts have proved that we are used to penetrate nozzle before tiltedly descale effect preferably.The anterior coning angle of this nozzle is 60 °, and injection diameter is Ф 1.2mm, and the center line of spray orifice and sprinkler body axis angle are 60 °, and four spray orifices are uniform.

Claims (2)

1, a kind ofly penetrates nozzle before tiltedly, be that being provided with inner chamber anterior in the nozzle body is the cone-beam mouth, nozzle intracoelomic cavity rear portion is a circular curve with anterior connecting, it is characterized in that the anterior circular cone ring wall of inner chamber is provided with several peripheral uniform spray orifices, spray orifice is to oblique the place ahead, and center line and nozzle body axis have certain included angle.

2, according to claim 1ly penetrate nozzle before tiltedly, it is characterized in that there is a plane perpendicular to the orifice center line in the spray orifice exit.
