Description

Technical Field

[0001] This utility model relates to the field of buffer device technology, and in particular to a pump station outlet water buffer device. Background Technology

[0002] With the rapid pace of urbanization, the volume of urban sewage discharge is also increasing. In the sewage treatment process, the sewage is introduced into sewage treatment pumping stations, where it is pumped into subsequent sewage treatment equipment.

[0003] Water has a certain impact force when it flows, especially at the connection between the valve and the pipe. When the valve is opened and closed, a large impact force is generated, which can cause great damage to the pipe. If the pipe is unstable, it is easy to shake a lot under the action of strong impact water flow. If this happens frequently, it is easy to loosen over time. Utility Model Content

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A pump station outlet buffer device includes a housing. An air-filled water hammer eliminator and an adjustable pressure reducing valve are installed inside the housing. The outlet of the air-filled water hammer eliminator is fixed to the interface of the adjustable pressure reducing valve. The air-filled water hammer eliminator and the adjustable pressure reducing valve are integrated into the housing, effectively absorbing water hammer during pump shutdown. The output pressure can be adjusted according to the downstream pipeline network requirements, protecting pipeline safety and simplifying installation. Through holes are provided on both sides of the housing, and auxiliary positioning components are equidistantly installed on both sides of the housing. An adjustment mechanism for adjusting the auxiliary positioning components is installed on the side of the housing.

[0007] The auxiliary positioning component includes a second gear rotatably mounted on the outer wall of the box, a swing arm coaxially fixed to the second gear, and a pressure roller fixed to the swing arm at a position away from the second gear.

[0008] As a further embodiment of this utility model, the adjusting mechanism includes a gear ring that meshes with the second gear, and a mounting ring frame is fixed to the side of the box body, with the gear ring slidably disposed within the mounting ring frame.

[0009] As a further embodiment of this utility model, the outer wall of the box is rotatably provided with a first gear that meshes with a gear ring. The first gear is coaxially fixed with a worm gear, and the worm gear is located on the inner wall of the box. The worm gear is equipped with a worm adapted to it, and the worm gear is coaxially fixed with a turntable.

[0010] As a further embodiment of this utility model, the inner wall of the box is fixed with a mounting box covering the worm gear and the worm, and the worm and the worm gear are rotatably disposed in the mounting box. The outer wall of the box is provided with a hole for the worm to pass through.

[0011] As a further embodiment of this utility model, the outer wall of the box body has an opening corresponding to the position of the mounting box, and the mounting box passes through the opening and is fixedly installed.

[0012] As a further embodiment of this utility model, a box cover is fixed to the top of the box body by bolts.

[0013] The beneficial effects of this utility model are as follows:

[0014] This utility model integrates an airbag-type water hammer eliminator and an adjustable pressure reducing valve into a housing, which can effectively absorb water hammer caused by pump shutdown and adjust the output pressure according to the needs of the downstream pipeline network, protecting the pipeline network and simplifying installation.

[0015] This utility model: The airbag-type water hammer eliminator and the water inlet and outlet of the adjustable pressure reducing valve are all connected to water pipes.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] Reference Figure 1-4 A pump station outlet buffer device includes a housing 1. The housing 1 is characterized by having an airbag-type water hammer eliminator 6 and an adjustable pressure reducing valve 7 installed inside. The outlet of the airbag-type water hammer eliminator 6 is fixed to the interface of the adjustable pressure reducing valve 7. The airbag-type water hammer eliminator 6 and the adjustable pressure reducing valve 7 are integrated into the housing 1, effectively absorbing water hammer caused by pump stoppage. The output pressure can be adjusted according to the downstream pipeline network requirements, protecting the pipeline network and simplifying installation. Through holes 3 are provided on both sides of the housing 1. Auxiliary positioning components 4 are installed equidistantly on both sides of the housing 1. An adjustment mechanism 5 is installed on the side of the housing 1 to adjust the auxiliary positioning components 4.

[0024] The auxiliary positioning component 4 includes a second gear 15 rotatably disposed on the outer wall of the box body 1, a swing arm 16 coaxially fixed to the second gear 15, and a pressure roller 17 fixed to the swing arm 16 at a position away from the second gear 15.

[0025] In this embodiment, the adjustment mechanism 5 includes a toothed ring 9 that meshes with the second gear 15, and a mounting ring frame 8 is fixed on the side of the housing 1. The toothed ring 9 is slidably disposed in the mounting ring frame 8.

[0026] In this embodiment, a first gear 11 that meshes with a gear ring 9 is rotatably provided on the outer wall of the box body 1. A worm gear 13 is coaxially fixed to the first gear 11, and the worm gear 13 is located on the inner wall of the box body 1. A worm 12 adapted to the worm gear 13 is provided on the worm gear 13, and a turntable 14 is coaxially fixed to the worm 12.

[0027] In this embodiment, the inner wall of the box body 1 is fixed with a mounting box 10 covering the worm gear 13 and the worm 12. The worm 12 and the worm gear 13 are rotatably disposed in the mounting box 10. The outer wall of the box body 1 is provided with a hole for the worm 12 to pass through.

[0028] In this embodiment, the outer wall of the box body 1 has an opening corresponding to the position of the mounting box 10, and the mounting box 10 is fixedly installed through the opening.

[0030] Working Principle: The system incorporates a housing 1, a cover 2, an airbag-type water hammer eliminator 6, an adjustable pressure reducing valve 7, auxiliary positioning components 4, and an adjustment mechanism 5.

The output pressure can be adjusted according to downstream pipeline requirements, protecting pipeline safety and simplifying installation. The airbag-type water hammer eliminator 6, its inlet, and the adjustable pressure reducing valve 7's outlet are all connected to water pipes, which pass through a through hole 3. The system operates by rotating the turntable 1. 4. This causes the worm gear 12 to drive the worm wheel 13 to rotate. Under the action of the first gear 11, the rotating worm wheel 13 causes the gear ring 9 to rotate, which in turn causes the first gear 11 to rotate. Finally, the second gear 15 drives the swing arm 16 to swing. Several pressure rollers 17 located on the same side retract towards each other, squeezing and positioning the outer wall of the pipe, thus providing support. This effectively solves the problems raised in the background technology, enabling the positioning and clamping of the pipe connection position, increasing support, and making it more stable. It is suitable for supporting and positioning pipes of different outer diameters.
