Detailed Description

The invention is further described below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on those shown in the drawings, and are used only for convenience in describing the present invention and for simplicity in description, and do not indicate or imply that the referenced devices or elements must have a particular orientation, be constructed and operated in a particular orientation, and thus, are not to be construed as limiting the present invention. Furthermore, the terms "first", "second", etc. are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first," "second," etc. may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless otherwise specified.

Referring to fig. 1-2, the fixed energy dissipater of the present invention mainly includes a cylindrical housing 1 and a cylindrical sleeve 2, the specific sleeve 2 is located inside the housing 1, and a cavity 3 is formed between an inner wall of the housing 1 and an outer wall of the sleeve 2, the sleeve 2 is composed of an outer sleeve 21, a middle sleeve 22 and an inner sleeve 23 which are spaced and cylindrical from each other from outside to inside in sequence, meanwhile, the circumferential walls of the outer sleeve 21, the middle sleeve 22 and the inner sleeve 23 are all provided with through holes 4 for water circulation, wherein one end of the inner sleeve 23 is a water outlet, in addition, one end of the housing 1 is provided with an energy dissipation orifice plate 5, the energy dissipation orifice plate 5 is provided with a plurality of water inlet holes for water to flow into the cavity, the other end of the housing 1 is provided with a pressure plate 6, the pressure plate 6 is connected with the housing 1 through bolts and presses and fixes the whole sleeve 2 in the housing 1, it should be noted that the water inlet hole on the energy dissipation pore plate 5 and the water outlet at one end of the inner sleeve 23 are respectively located at two ends of the shell 1, in use, water flows into the cavity 3 from the water inlet hole on the energy dissipation pore plate 5, then sequentially passes through the outer sleeve 21, the middle sleeve 22 and the inner sleeve 23 through the through hole 4, and finally flows out from the water outlet at one end of the inner sleeve 23, it should be noted that channels through which water flows all form flow channels, the flow channels in the invention are all designed in radial symmetry, and the design facilitates the water flow to form collision energy dissipation inside the energy dissipater, so that the energy dissipater can operate stably, and the cavitation performance is high.
