Problems solved by technology

Nozzles for ships use open cone nozzles. The disadvantage of existing open cone nozzles is that their structure limits the power of water spraying. Part of the reason is that the nozzles have a large taper, and high-pressure water passes through the nozzle after being sprayed out. The dispersion effect of the cone surface leads to insufficient injection power and low injection efficiency

Embodiment Construction

[0014] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0015] See figure 1 , figure 2 , the present invention includes a casing 2, a cavity 1, a cone 3 and a joint 4. The cone 3 is fixed between the cavity 1 and the joint 4 by means of the casing 2 . The joint 4 has a through hole 41, and the end surface has a conical surface 40, and the conical surface 40 can reduce the water outlet hole to increase the spray pressure.

[0016] See Fig. 3, Figure 4 The conical body 3 has a conical surface 30 and spray holes, the spray holes include a central spray hole 31 and circumferential spray holes 32 , 33 and 34 perpendicular to the conical surface 30 . The cavity 1 has a central hole 12 and reflective surfaces 10, 11 and 13 corresponding to the circumferential injection holes of the cone body 3, and each reflective surface is an arc surface.

[0017] Working process of the present invention is as ...

Abstract

The invention relates to a marine high-pressure spraying nozzle which comprises a sleeve shell, a cavity, a conical body and a connector. The marine high-pressure spraying nozzle is characterized in that the conical body is fixed between the cavity and the connector through the sleeve shell, the sleeve shell, the cavity and the connector are connected through threads, the conical body is provided with a spraying hole, and the sleeve shell is provided with a reflection face corresponding to the spraying hole. The marine high-pressure spraying nozzle overcomes the defects that an existing high-pressure spraying nozzle is insufficient in spraying power, and low in spraying efficiency, an arc face reflection type spraying mode is used, the spraying power is enhanced, the spraying effect is improved, and stability of a ship is further improved.

Description

technical field [0001] The invention relates to the field of ship equipment, in particular to a ship nozzle. technical background [0002] During the sailing process, the ship is usually pushed forward by the propeller. If the propulsion force of the propeller is not enough, a jetting device is usually added at the stern of the ship to assist the ship's navigation. The jetting device can not only provide part of the power for the ship, but also assist the ship's turns and improves the smoothness of the boat. The commonly used injection device is a high-pressure nozzle, and the injection of the high-pressure nozzle is realized through the nozzle at the end of the nozzle. Nozzles for ships use open cone nozzles. The disadvantage of existing open cone nozzles is that their structure limits the power of water spraying. Part of the reason is that the nozzles have a large taper, and high-pressure water passes through the nozzle after being sprayed out. The dispersion effect of t...
