Description

High-pressure wash compound nozzle

Technical field

The utility model relates to cleaning technique fields, and in particular to and a kind of pair of tubular member carries out the nozzle of high-pressure wash, More particularly to a kind of high pressure cleaning nozzle that for diesel common rail engine etc. cleannes are required with very high tubular member.

Background technique

High-pressure wash is that high pressure water flow is generated by high-pressure pump to rinse a kind of process of body surface.Diesel common rail The accurate pipe part of engine etc. cleannes are required it is very high, can will be in tubulose precision component using high-pressure wash method Dirt, attachment and tamper are removed, are washed away, achieving the purpose that clean completely.Insertion is generallyd use in the prior art to be less than It is cleaned the jet pipe of caliber, circular hole spout, injection water and cleaned part relative motion are radially processed on jet pipe, is guaranteed high Pressure water flow can be washed into the every place surface of part, to guarantee cleaning effect, but when due to pipe part cleaning cleaning solution by tube wall Constraint can not form effective flowing, can only overflow, and impurity is deposited in inner bore of part table in cleaning solution after shaking repeatedly Face influences cleaning effect, simultaneously because elongated jet pipe is generated vibration by the reaction of injection water, again may with hole wall collision Generate new particulate matter.

Summary of the invention

Cleaning solution can not form effective flowing by tube wall constraint when to solve pipe part of the existing technology cleaning, only The problem of energy overflows, and impurity is deposited in inner bore of part surface in cleaning solution after shaking repeatedly, influences cleaning effect, this Utility model provides high-pressure wash compound nozzle.The high-pressure wash compound nozzle of the utility model, including with can spiral The nozzle body of the spout threads connection of reciprocating motion, the nozzle body are axially provided with cavity, it is characterised in that: described The spaced radial of nozzle body is arranged two groups of reversed spray orifices, two groups of reversed spray orifices axis with the nozzle body respectively Line forms tilt angle, and two groups of reversed spray orifices are connected to the cavity.

Further, at least one helix channel-shaped spray orifice, the helix are provided between two groups of reversed spray orifices Channel-shaped spray orifice is connected to the cavity.

Further, the helix groove width of the helix channel-shaped spray orifice is less than the hole of two groups of reversed spray orifices Diameter.

Further, the partial outer face of the nozzle body is in melon prism-shaped, opens up one on the melon prism concave surface The reversed spray orifice of group.

Further, the melon prismatic surface is quartering melon prism, and one is opened up on each melon prism concave surface instead To spray orifice.

Further, two groups of reversed spray orifices form 25 degree of tilt angles with the axis of the nozzle body respectively.

Further, the axis of the helix channel-shaped spray orifice and the nozzle body is at 45 degree.

The high-pressure wash compound nozzle of the utility model has following good effect, and the high-pressure wash of the utility model is multiple Box-like nozzle has opened up combined type spray orifice, after nozzle is completely into pipe part, is formed at the both ends of nozzle contrary Two-way water flow forms negative relative area, and will cleaning under high speed, the water impact and Venturi effect of high pressure in the middle part of nozzle Cleaning solution afterwards takes away as far as possible, reduces the residual of cleaning solution.Simultaneously nipple top use melon fusiform structure, guarantee guiding and In the case of the support of jet pipe, the contact with hole wall is reduced as far as possible and increases water-outlet area, improve the effect of cleaning, improve clearly Wash efficiency.

Specific embodiment

To further illustrate the principles of the present invention and structure, the embodiments of the present invention are carried out now in conjunction with attached drawing It is described in detail.

The high-pressure wash compound nozzle of the utility model, including with can the jet pipe 5 that moves back and forth of spiral be threadedly coupled Nozzle body 1, the nozzle body 1 is axial to be provided with cavity, it is characterised in that: the spaced radial of the nozzle body 1 is set Two groups of reversed spray orifices 2 are set, the reversed spray orifice 2 of described two groups forms tilt angle, institute with the axis of the nozzle body 1 respectively The reversed spray orifice 2 of two groups stated is connected to the cavity.

Further, at least one helix channel-shaped spray orifice 3, the spiral are provided between two groups of reversed spray orifices 2 Wire casing shape spray orifice 3 is connected to the cavity.

In a preferred embodiment, 2 helix channel-shaped spray orifices 3 are provided between two groups of reversed spray orifices 2.

Further, the helix groove width of the helix channel-shaped spray orifice 3 is less than the hole of two groups of reversed spray orifices 2 Diameter.

Further, the partial outer face of the nozzle body 1 is in melon prism-shaped, opens up one on the melon prism concave surface The reversed spray orifice 2 of group.

Further, the melon prismatic surface is quartering melon prism, and one is opened up on each melon prism concave surface instead To spray orifice.

Further, described two groups reversed spray orifices 2 form 25 degree of inclinations angle with the axis of the nozzle body 1 respectively Degree.

Further, the axis of the helix channel-shaped spray orifice 3 and the nozzle body 1 is at 45 degree.

Nozzle enter part spin move when, combined type spray orifice by the high-pressure cleaning liquid in jet pipe be converted into three roads height Press water beam, at the top and bottom of high pressure water beam sprayed, rinsed in the opposite direction respectively, by high speed, high pressure water The impurity of hole wall and particulate matter are removed, are washed out by stream impact, and are taken away by flowing water flow.Zigzag shape in the middle part of nozzle Spout is smaller compared to circular hole nozzle exit product, but in nozzle screw, it is bigger to rinse area.Cleaning after cleaning Under the Venturi effect that both ends water impact is formed, middle part cleaning solution is taken away liquid as far as possible, reduces the residual of cleaning solution； Melon prismatic 4 point contact in top not only ensure that guiding when jet pipe 5 enters pipe part 4, but also play support jet pipe 5, avoid Jet pipe 5 taps the new cleannes risk of hole wall bring because of vibration.

The above, only the utility model preferred embodiment, therefore the utility model implementation cannot be limited with this Range should still belong to this reality that is, according to equivalent changes and modifications made by present utility model application the scope of the patents and description In the range of being covered with new patent.
