Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be described clearly and completely with reference to the accompanying drawings.
In a first embodiment, as shown in fig. 1 to 4, a water supply pump station with a water hammer prevention device includes a water inlet pipe 1, an energy dissipation tank 2 and an air pressure tank 3, wherein a water inlet 4 is arranged at one side of the water inlet pipe 1, a plurality of water outlets 5 are arranged at the other side of the water inlet pipe 1, each water outlet 5 is connected with one side of a water outlet pipe 7 through a pipe valve system 6, the other side of the water outlet pipe 7 is communicated with an inlet end of the energy dissipation tank 2 through a connecting pipeline 8, an outlet end of the energy dissipation tank 2 is connected with one end of a branch pipe 9, the other end of the branch pipe 9 is communicated with an inlet end of the air pressure tank 3, a pressure relief pipeline 10 is fixedly connected in the middle of the branch pipe 9, and a pressure holding relief valve 11 is installed on the pressure relief pipeline 10; a plurality of energy dissipation plates 12 are arranged in parallel in the energy dissipation tank 2.
In the present embodiment, a pressurizing device 18 is installed in the middle of each pipe valve system 6, and a detection system 19 is installed on the water outlet pipe 7. The pressurizing device 18 and the detection system 19 play roles of pressurizing and stabilizing pressure in the water delivery process; this is the prior art and is not described in detail.
The working principle is as follows:
in the water delivery process, when a backflow water hammer occurs, the water hammer enters the energy dissipation tank 2 through the pipe valve system 6 and the connecting pipeline 8, and partial cut-off closing water hammer is absorbed by the plurality of energy dissipation plates 12 in the energy dissipation tank 2; when the energy dissipation tank 2 is filled with the backflow medium, the energy dissipation function is lost, at the moment, the conveying medium enters the air pressure tank 3 through the branch pipe 9, the residual water hammer energy is absorbed through the bag type structure in the air pressure tank 3, meanwhile, the gas in the tank body is compressed, and the gas is continuously acted through the air bag; when the internal pressure value of the air pressure tank 3 reaches the design upper limit and reaches the opening given value of the pressure maintaining relief valve 11, the pressure maintaining relief valve 11 is automatically opened, the residual pressure is removed, and the process is finished. Therefore, the water hammer caused by the medium backflow of the water delivery pipe network due to the instantaneous pump stop is quickly eliminated through the water hammer eliminating system consisting of the energy dissipation tank 2 and the air pressure tank 3.
In the second embodiment, as a further preferable scheme of the first embodiment, a middle hole 13 is formed in the middle of the energy dissipation plate 12, and four circular holes 14 are uniformly formed in the edge of the energy dissipation plate 12. The setting number of the energy dissipation plates 12 and the size of an opening on the surface of each energy dissipation plate 12 are determined according to the flow of a pump station; in this embodiment, the energy dissipation plates 12 include a plurality of first energy dissipation plates 15 and a plurality of second energy dissipation plates 16, the first energy dissipation plates 15 are located below the outlet end of the energy dissipation tank 2, the second energy dissipation plates 16 are located above the outlet end of the energy dissipation tank 2, the radius of the middle holes 13 of the first energy dissipation plates 15 is larger than that of the circular arc holes 14, and the radius of the middle holes 13 of the second energy dissipation plates 16 is equal to that of the circular arc holes 14. Therefore, when water flows through the energy dissipation plate 12, because the middle hole and the circular arc hole of the energy dissipation plate 12 are smaller than the inner diameter of the energy dissipation tank 2, the water flow generates local resistance which is suddenly contracted and suddenly amplified, thereby reducing the potential energy of the water body and achieving the effect of energy dissipation.
In the third embodiment, as a further preferable scheme of the first embodiment, the connection pipeline 8, the outlet end of the energy dissipation tank 2, the inlet end of the air pressure tank 3 and the pressure relief pipeline 10 are respectively provided with a detection valve 17. The opening and closing of the energy dissipation tank 2 and the air pressure tank 3 can be respectively controlled by arranging the detection valve 17, so that the maintenance work of the water supply pump station can be carried out.
The above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
