Embodiment Construction

[0022] The technical characteristics of the present invention will be further described below in conjunction with the accompanying drawings.

[0023] Figure 1 to Figure 2 A first advantageous embodiment of the fan nozzle according to the invention is schematically shown in , the nozzle body as a whole in figure 1 marked. The fan nozzle comprises an upper inlet section 6 with a cylindrical shape.

[0024] The flow channel extends from the upper end face through the nozzle body 1 to the lower end face. The flow channel has a cylindrical inlet section 6 with a circular flow cross section. Adjoining the central part 2 is a beam-shaping section 4 which tapers continuously in the flow direction 7 of the fluid flowing through the flow channel, i.e. the flow cross-section of the beam-shaping section 4 follows the flow direction 7 decreases continuously.

[0025] The jet-shaping section 4 extends to the nozzle opening 3 , which is characterized by the smallest flow cross-section ...

Abstract

In the work, a novel fan-shaped nozzle applied to high-pressure cleaning equipment (a cleaning machine and a cleaning and sweeping vehicle) is provided. The fan-shaped nozzle is provided with a nozzle body through which a flow channel for fluid passes, wherein the flow cross-section of the flow channel continuously becomes thin in the beam forming section. According to the fan-shaped nozzle, by changing the structure of the flow channel of the nozzle, steps influencing the pressure loss of water flow are removed, and the angle of the beam forming section is optimized, so that the pressure loss of the water flow is reduced, and the striking force of the water flow is improved. Due to the continuous transition and the optimization of the angle of the forming section, the flow loss can be kept very small. Accordingly, the fan-shaped nozzle according to the present invention is characterized by having beam shaping with minimal pressure loss, and compared with other types of cleaning type nozzles, the fan-shaped nozzle can effectively improve cleaning efficiency and reduce the energy loss to the maximum degree.

Description

technical field [0001] The invention relates to the field of model design, and proposes a fan-shaped nozzle applied to high-pressure cleaning equipment (cleaning machine, washing and sweeping vehicle), the fan-shaped nozzle has a nozzle body, and the flow channel for fluid passes through the nozzle body, wherein, in In the beam-shaping section, the flow cross-section of the flow channel tapers continuously. Background technique [0002] With the development of society, people's awareness of environmental protection has begun to strengthen. As an environmentally friendly cleaning method, high-pressure water jet cleaning has the characteristics of low cleaning cost, fast speed, high cleaning rate, no damage to the cleaned object, wide application range, and no environmental pollution. . Therefore, the development and design of high-efficiency and energy-saving cleaning nozzles has become a hot spot for researchers. [0003] Fan nozzles are known which have a low inlet pressu...
