Description
Technical Field
The invention relates to the technical field of spray heads, in particular to a high-wear-resistance self-advancing high-pressure spray head.
Background
High pressure jets play a significant role in everyday life applications, for example, self-propelled cleaning jets used in cities to clean sewers are one type of high pressure jets. The traditional high-pressure spray head is easy to corrode and deform at the water outlet due to high-speed washing of water flow, so that the service life of a product is greatly shortened, and huge resource waste is formed. The high-pressure spray head is easy to generate huge corrosion on the inner surface of the high-pressure spray head, particularly the vicinity of a water outlet, due to the washing of extremely high-speed water flow, and the short service life of the high-pressure spray head is one of the most critical reasons. Although modern machining techniques have been developed, there are still many problems in machining deep and long holes. The problems of dimensional accuracy error, edge surface generation on the inner surface of the hole, and the like are easily caused. These problems also create a potential for a shorter life of the sprinkler in the future. In addition, the service life of the spray head can be greatly reduced if the spray head is operated at high temperature or abnormal temperature for a long time.
In conclusion, how to reduce the abrasion of the water flow to the spray head becomes a problem which needs to be solved urgently by researchers of the company.
Disclosure of Invention
The technical problem to be solved by the invention is as follows: how to reduce the abrasion of the water flow to the spray head;
in order to solve the technical problems, the invention adopts the following technical scheme:
the invention relates to a high wear-resistant self-advancing high-pressure spray head, which comprises: a nozzle body; the first water outlet is formed in the top end of the spray head body; the second water outlet is circumferentially arranged at the tail end of the spray head; the inner cavity is arranged in the spray head body and communicated with the first water outlet and the second water outlet; wherein, the inner cavity is conical, and the inclined inner wall of the inner cavity forms an included angle of 15-75 degrees with the central line of the nozzle body;
in the scheme, the nozzle body is streamline in appearance, so that the resistance on the outer surface is reduced in the cleaning process, and the cleaning efficiency and the working speed are improved; the first water outlet is a long and thin hole and is always in a high-pressure water flow impact state in work; the second water outlets are uniformly distributed at the tail part of the spray head body, the second water outlets are used for discharging redundant high-pressure water flow from the tail part to reduce the overlarge pressure of the inner cavity of the spray head, and meanwhile, the discharged water flow can provide forward thrust to enable the spray head to have self-propelling capacity;
the inner cavity is designed in a conical shape, and the conical degree is in an interval of 15-75 degrees with the central line, so that the impact of water flow on the inner wall is reduced, and the water flow injection is smoother.
Furthermore, on the symmetrical surface of the spray head body, the included angle between the axis of the second water outlet and the central line of the spray head body is inclined; when viewed from the tail end face of the nozzle body, the included angle between the axis of the second water outlet and the vertical line is c, and the c is 5-40 degrees.
That is, on the two-axis coordinates of the nozzle body, the axis of the second water outlet is obliquely arranged with the two axes of the coordinate axis, so that the self-advancing nozzle can generate self-advancing thrust in work, and meanwhile, the deflection angle can slightly drive the nozzle to enable the nozzle to generate self-rotation so as to increase the force generated in propulsion; and the sprayed water can effectively wash away dirt generated after cleaning.
The invention has the beneficial effects that: the invention relates to a high-wear-resistance self-advancing high-pressure spray head, wherein the inner cavity is designed in a conical shape, and the conical degree is in a range of 15-75 degrees with the central line, so that the impact of water flow on the inner wall is reduced, and the water flow is sprayed more smoothly.

Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic views illustrating only the basic structure of the present invention in a schematic manner, and thus show only the constitution related to the present invention.
The nozzle body 1 of the invention is streamline in shape as shown in figure 1, so that the resistance on the outer surface is reduced in the cleaning process, and the cleaning efficiency and the working rate are improved. As shown in the cross-sectional view of fig. 2, the top end of the nozzle body 1 is provided with a first water outlet 2, and the first water outlet 2 is an elongated hole and is always in a high-pressure water flow impact state during operation. As shown in fig. 2, at the tail of the nozzle body 1, there are a plurality of uniformly distributed second water outlets 3 at the tail, and the purpose of these second water outlets 3 is to discharge the excess high-pressure water flow from the tail to reduce the excessive pressure in the inner cavity 4 of the nozzle body, and at the same time, these discharged water flows can provide forward thrust so that the nozzle body 1 has the capability of self-propulsion. The inner cavity 4 is designed to be conical as shown in fig. 2, the included angle between the conical degree and the central line is a, and the included angle a is in the range of 15-75 degrees, so that the impact of water flow on the inner wall is reduced, and the water flow is sprayed more smoothly. As shown in fig. 3, the second water outlet 3 at the tail part has a deflection angle of 15 to 40 degrees with the center line of the product, the angle is c, so that the water outlet not only can generate self-advancing thrust when the water outlet works, but also can slightly drive the nozzle body 1 to generate self-rotation so as to increase the force generated when the water outlet is pushed; and the sprayed water can effectively wash away dirt generated after cleaning.
In order to achieve high wear resistance, the inner and outer surface nozzles of the high-pressure nozzle need to be subjected to super-hardening treatment, and the selected TD coating treatment process is as follows: 1. firstly, roughly processing and forming a workpiece; 2. quenching and tempering the workpiece: high temperature quenching (1020-. 3. The workpiece is finished, in particular the inner cavity 4 and the surface are polished to facilitate the growth and infiltration of carbides on the surface. 4. TD treatment is carried out in a well type resistance furnace, and the formula of salt bath is as follows: 85% Na2B4O7+5％B4C+10％V2O5The salt bath time is 6 hours, so that a layer of metal carbide layers of vanadium, niobium, chromium, titanium and the like with the sizes of several micrometers to more than twenty micrometers is formed on the inner surface and the outer surface of the workpiece. 5. Finally, polishing the inner part and the outer part of the processed workpieceAnd (4) finishing.
In light of the foregoing description of the preferred embodiment of the present invention, many modifications and variations will be apparent to those skilled in the art without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
