DETAILED DESCRIPTION

[0021] like Figure 1-4 As shown, a high-efficiency noise reduction, drainage and wave absorbing device comprises a sealed shell, a through hole 1 is respectively provided on the left and right walls of the shell, an elastic plate is provided on the inner top wall of the shell through a lifting mechanism, the elastic plate is perpendicular to the axis of the through hole 1 in a normal state, a spherical soft layer 2 matching the through hole 1 is provided on the front and back surfaces of the elastic plate, and the switch of the lifting mechanism is provided on the outer surface of the shell.

[0022] In this embodiment, when in use, the shell is installed between the two ends of the pipeline, that is, the through hole 1 on the left side wall of the shell and the through hole 1 on the right side wall are both connected to the pipeline, and the flow of the liquid in the pipeline passes through the interior of the shell. When the switch (valve) on the pipeline is closed or opened, assuming that the valve is set on the left side of the shell, the shell and the valve are connected in series on the pipeline. When the valve is suddenly opened, the shock wave generated at this time enters the shell from the through hole 1 on the right side of the shell and hits the elastic plate at the same time. The elasticity of the elastic plate buffers the liquid in the shell. At the same time, after the impact of the shock wave, the elastic plate is impacted to the left side of the shell. At this time, the spherical soft layer 2 on the elastic plate will partially block the through hole 1 on the left side wall of the shell, that is, reduce the flow of the through hole 1 on the left side wall of the shell, thereby avoiding the switch (valve) on the pipeline from being separated from the pipeline under the action of the shock wave in the pipeline, and due to the existence of the spherical soft layer 2, when the elastic plate is impacted by the shock wave and hits the edge of the through hole 1, it will not make too much noise, thereby playing a noise reduction role.

[0023] As a preferred mode, the elastic plate includes a transverse root 3 and a longitudinal actuator 4, the shape and size of the transverse root 3 are consistent with the shape and size of the inner top wall of the shell, the top of the longitudinal actuator 4 is fixedly connected to the lower surface of the transverse root 3, the transverse root 3 is fixedly connected to the actuator end of the lifting mechanism, the front and back surfaces of the longitudinal actuator 4 are perpendicular to the axis of the through hole 1, the front and back surfaces of the longitudinal actuator are provided with the spherical soft layer 2, and the side wall of the transverse root 3 is slidably connected to the inner side wall of the shell. The transverse root 3 is used to be fixedly connected to the actuator end of the lifting mechanism, so that when it is necessary to adjust the degree of blocking of the through hole 1 by the spherical soft layer 2 during the process of the shock wave impacting the longitudinal actuator 4, the elastic plate is adjusted to descend or ascend through the lifting mechanism. At the same time, the transverse root 3 is also provided to ensure the airtightness inside the shell during the process of the lifting mechanism controlling the longitudinal actuator 4 to ascend and descend.

[0024] As a preferred mode, the lifting mechanism includes a screw hole 5, a bolt 6, a nut 7, and a bearing 8. The screw hole 5 is provided through the top wall of the shell. The upper surface of the transverse root 3 is rotatably connected to the lower end of the bolt 6 through the bearing 8. The upper end of the bolt 6 passes through the screw hole 5 and extends outside the shell. The bolt 6 is perpendicular to the transverse root 3. The two ends of the bolt 6 are threadedly connected to the screw hole 5. The two ends of the bolt 6 are threadedly connected to the nut 7 outside the shell. After such a configuration, the elastic plate can be controlled to rise or fall by rotating the bolt 6. At the same time, after adjustment, the bolt 6 is locked by the nut 7.

[0025] As a preferred mode, it also includes an annular elastic soft sealing sheet 9, one end of the annular elastic soft sealing sheet 9 is tightly connected to the lower surface of the transverse root 3, the other end of the annular elastic soft sealing sheet 9 is tightly connected to the front, back, left and right inner side walls of the shell, and the top wall of the shell is provided with a vent hole 10. In this way, by providing the elastic soft sealing sheet 9, the air tightness inside the shell can be ensured without requiring the circumference of the transverse portion 3 to be completely in close contact with the inner side wall of the shell, and at the same time, the elastic plate does not affect the rise and fall of the elastic plate under the control of the lifting mechanism; the vent hole 10 is provided to release the airflow in the space formed by the elastic plate, the elastic soft sealing sheet 9 and the inner top wall of the shell during the rise and fall of the elastic plate.

[0026] As a preferred mode, the shell is composed of an upper shell unit 11 and a lower shell unit 12, the elastic plate is arranged in the upper shell unit 11, the through hole 1 is arranged on the side wall of the lower shell unit 12, the upper shell unit 11 and the lower shell unit 12 are locked together by a bolt assembly, and the annular end of the elastic soft sealing sheet 9 away from the transverse root 3 is clamped together by the lower edge of the upper shell unit 11 and the upper edge of the lower shell unit 12. After such arrangement, it is convenient to install the elastic plate in the shell, and at the same time, the edge of the elastic soft sealing sheet 9 is clamped together by the lower edge of the upper shell unit 11 and the upper edge of the lower shell unit 12, which can play a role in fixing the elastic soft sealing sheet 9 and can ensure the airtightness in the shell. The material of the elastic soft sealing sheet 9 can be made of conventional elastic rubber.

[0027] As a preferred mode, a groove 13 is provided on the lower edge of the upper shell unit 11, and a protrusion 14 cooperating with the groove is provided on the upper edge of the lower shell unit 12. The arrangement of the groove 13 and the protrusion 14 ensures that the elastic soft sealing sheet 9 is not easy to slip during the process of being clamped by the upper shell unit 11 and the lower shell unit 12, and at the same time, it can increase the area of ​​the elastic soft sealing sheet 9 squeezed by the upper shell unit 11 and the lower shell unit 12, thereby further ensuring the airtightness in the shell.

[0028] As a preferred embodiment, a flange connection end 15 is provided on the outer side wall of the shell at the through hole 1. The flange connection end 15 is provided to facilitate installation of the shell on the pipeline.

[0029] Preferably, it also includes a diffusion chamber 1, which is a container with a volume greater than that of the shell. When in use, the diffusion chamber 1 and the shell are connected in series and then arranged between the two ends of the pipeline. Figure 4 As shown, after such arrangement, the residual waves eliminated in the shell enter the diffusion chamber 1 for diffusion, and are thus dissipated in the diffusion chamber 1 .
