Description

Technical Field

[0001] This utility model belongs to the field of silencer pipe technology, specifically relating to a water inlet silencer pipe. Background Technology

[0002] Water inlet pipes are pipes used to introduce water or other liquids into equipment, systems or containers. They are commonly found in household appliances, industrial equipment, building water supply systems, and especially in urban secondary water supply systems, where water inlet pipes are among the most frequently used pipes.

[0003] In existing secondary water supply systems, the inlet pipe's function is to deliver water to the secondary water supply tank. Currently, the inlet pipe of the secondary water supply tank often uses a free-flow method. However, even after the water flow is reduced in pressure by a pressure reducing valve, there is still a free water pressure of several meters. When this free-flowing water enters the tank through the inlet pipe, it violently impacts the water surface and tank walls, generating significant water flow noise and vibration, and may even cause structural resonance, affecting nearby residents. If the tank's inlet water is directly submerged, on the one hand, short-circuiting can easily occur, creating hydraulic dead zones within the tank, affecting water quality and increasing the risk to water supply safety; on the other hand, when the municipal water supply network experiences a sudden pressure drop due to maintenance, pipe bursts, or other factors, the water in the tank can siphon back into the municipal water supply network, affecting water supply safety. Therefore, it is necessary to optimize the outlet method and structure of the secondary water supply tank's inlet pipe to solve these problems. Utility Model Content

[0004] The purpose of this utility model is to provide a water inlet silencer pipe with a simple structure and reasonable design in order to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A water inlet silencer pipe includes a water inlet pipe, a first fixing plate fixedly installed at the bottom of the water inlet pipe, and a second fixing plate attached to the bottom of the first fixing plate. The first fixing plate and the second fixing plate are fixedly connected by a second bolt. A connecting pipe is fixedly installed at the bottom of the second fixing plate. An overflow sleeve is fixedly installed on the outside of the top of the connecting pipe. A second base sleeve is fitted on the outside of the connecting pipe. A first base sleeve is fitted on the outside of the overflow sleeve. Several first reinforcing ribs are provided at the connection between the upper surface of the outer wall of the overflow sleeve and the connecting pipe.

[0007] Preferably, a base plate is fixedly installed at the bottom of the No. 1 base sleeve, and the base plate is fixedly installed at the bottom of the pool by several No. 1 bolts. A metal baffle is fixedly installed at the bottom of the No. 1 bolts, and the metal baffle is in contact with the bottom of the pool.

[0008] Preferably, a number of No. 2 reinforcing ribs are provided at the connection between the bottom of the outer wall of the No. 2 base sleeve and the upper surface of the base plate, and the base plate is fixedly installed on the No. 1 bolt by nuts.

[0009] Preferably, a number of positioning plates are uniformly fixedly installed on the outside of the bottom of the connecting pipe. The bottom of the connecting pipe is located inside the No. 2 base sleeve, the upper part of the No. 2 base sleeve is located inside the overflow sleeve, the lower part of the overflow sleeve is located inside the No. 1 base sleeve, and a number of No. 3 reinforcing ribs are provided at the connection between the bottom of the outer wall of the No. 1 base sleeve and the base plate.

[0010] Preferably, a screw is fixedly installed at the bottom center of the base plate, and the screw passes through the top center of the base plate and is threaded to a threaded block. Several connecting rods are evenly fixedly installed on the outside of the threaded block, and the outside of the multiple connecting rods is fixedly connected to the inner wall of the connecting pipe.

[0011] Preferably, the upper part of the water inlet pipe is provided with an anti-siphon hole, and a flange is fixedly installed at the end of the water inlet pipe away from the second fixing plate.

[0012] The beneficial effects of this utility model are as follows: This utility model delivers water to the base sleeve through the water inlet pipe. After the water fills the two-stage base sleeve, it overflows from the gap between the first base sleeve and the overflow sleeve. The overflow outlet replaces the traditional direct discharge method, avoiding the situation where the water flow directly impacts the water surface and pool wall, effectively reducing the noise and vibration during water intake, and achieving noise reduction during water intake. The threaded setting between the threaded block and the screw allows for adjustment of the distance between the bottom edge of the connecting pipe and the base plate. Attached Figure Description

[0018] Example

[0019] Please see Figure 1 and Figure 2 A water inlet silencer pipe includes a water inlet pipe 1. A first fixing plate 2 is fixedly installed at the bottom of the water inlet pipe 1, and a second fixing plate 12 is attached to the bottom of the first fixing plate 2. The first fixing plate 2 and the second fixing plate 12 are fixedly connected by a second bolt 9. A connecting pipe 13 is fixedly installed at the bottom of the second fixing plate 12. An overflow sleeve 7 is fixedly installed on the outside of the top of the connecting pipe 13. A second base sleeve 19 is sleeved on the outside of the connecting pipe 13. A first base sleeve 3 is sleeved on the outside of the overflow sleeve 7. Several first reinforcing ribs 8 are provided around the connecting pipe 13 at the connection between the upper surface of the outer wall of the overflow sleeve 7 and the connecting pipe 13.

[0020] In use, the inlet pipe 1 is used for water intake, the first fixing plate 2, the second fixing plate 12 and the second bolt 9 are used to connect the inlet pipe 1 and the connecting pipe 13, and the first reinforcing rib 8 is used to enhance the structural strength between the connecting pipe 13 and the overflow sleeve 7.

[0021] Please see Figure 2 and Figure 3 A base plate 6 is fixedly installed at the bottom of the first base sleeve 3. The base plate 6 is fixedly installed at the bottom of the pool by several first bolts 5. A metal baffle 4 is fixedly installed at the bottom of the first bolts 5. The metal baffle 4 is in contact with the bottom of the pool. Several second reinforcing ribs 17 are provided at the connection between the bottom of the outer wall of the second base sleeve 19 and the upper surface of the base plate 6. The base plate 6 is fixedly installed on the first bolts 5 by nuts. Several positioning plates 14 are evenly fixedly installed on the outside of the bottom of the connecting pipe 13. The bottom of the connecting pipe 13 is located inside the second base sleeve 19. The upper part of the second base sleeve 19 is located inside the overflow sleeve 7. The lower part of the overflow sleeve 7 is located inside the first base sleeve 3. Several third reinforcing ribs 20 are provided at the connection between the bottom of the outer wall of the first base sleeve 3 and the base plate 6.

[0022] In use, the positioning piece 14 is used to position the connecting pipe 13 and the second base sleeve 19.

[0023] Please see Figure 1 , Figure 2 and Figure 3A screw 18 is fixedly installed at the bottom center of the base plate 6. The screw 18 passes through the top center of the base plate 6 and is threaded to a threaded block 15. Several connecting rods 16 are evenly fixedly installed on the outside of the threaded block 15. The outside of the multiple connecting rods 16 is fixedly connected to the inner wall of the connecting pipe 13. An anti-siphon hole 10 is opened at the top of the water inlet pipe 1. A flange 11 is fixedly installed at the end of the water inlet pipe 1 away from the second fixed plate 12.

[0024] In use, flange 11 is used for the installation of water inlet pipe 1, and anti-siphon hole 10 is used to balance the pressure inside and outside of water inlet pipe 1 to avoid backflow of water. When installing water inlet pipe 1, first use flange 11 to install water inlet pipe 1 into the main pipeline of the system. Rotate base plate 6 to drive screw 18 to rotate synchronously. By adjusting the position between screw 18 and threaded block 15, it is easy to adjust the distance between base plate 6 and bottom edge of connecting pipe 13 according to the depth of the pool.

[0025] It should be noted that, in the use of this type of inlet silencer pipe, the inlet pipe 1 is first fixedly installed into the main pipeline of the system using flange 11. Then, the first fixing plate 2 and the second fixing plate 12 are attached and fixed together using bolt 9, so that the connecting pipe 13 and the overflow sleeve 7 fixedly connected to it are connected to the bottom of the inlet pipe 1, thus achieving the fixed installation of the overflow sleeve 7. The first reinforcing rib 8 is used to enhance the structural strength between the overflow sleeve 7 and the connecting pipe 13. Then, the second base sleeve 19 is inserted between the bottom of the overflow sleeve 7 and the connecting pipe 13. Rotating the base plate 6 simultaneously drives the screw 18 to rotate, adjusting the position between the screw 18 and the threaded block 15 to facilitate adjusting the distance between the bottom plate 6 and the bottom edge of the connecting pipe 13 according to the depth of the water tank. Rotate until the specified length is reached. Nuts are welded to the lower surface of the holes on the base plate 6. After passing the first bolt 5 through the nut, screw the movable nut into the bottom of the first bolt 5 and insert the metal baffle 4 into the bottom of the first bolt 5. Use the first bolt 5 to press the metal baffle 4 into contact with the bottom of the pool. Then screw the movable nut towards the bottom of the first bolt 5 until the movable nut presses the metal baffle 4 tightly against the bottom of the pool, thus achieving stable installation of the metal baffle 4. The base plate 6 is then mounted on the first bolt 5, thus realizing the installation of the water inlet silencer pipe. Water enters the connecting pipe 13 from the water inlet pipe 1, and then enters the second base sleeve 19 from the connecting pipe 13. After filling the second base sleeve 19, water flows from the gap between the second base sleeve 19 and the connecting pipe 13 into the water inlet. The water overflows upwards, refilling the No. 1 base sleeve 3. Water then overflows upwards from the gap between the No. 1 base sleeve 3 and the overflow sleeve 7, achieving upward overflow. This fully agitates the water in the pool, increasing water circulation and effectively preventing the formation of hydraulic dead zones. Furthermore, by installing a silencer at the outlet of the inlet pipe 1 and fixing the base plate 6 to the bottom of the pool with bolts, the installation of the silencer outlet is secure, reducing vibration noise from the outlet structure. In addition, compared to the traditional inlet pipe 1, installing a silencer at the outlet of the inlet pipe 1 ensures that the water flow from the inlet pipe to the silencer outlet remains full, extending the time of full flow and effectively preventing gas-liquid two-phase noise. A flow-guiding structure is also employed. The structure alters the direction of the incoming water flow, thus reducing pressure. Furthermore, when the outlet of the silencer is submerged below the water surface, the outflow velocity is reduced, minimizing the impact of the outflow on the water in the pool and reducing turbulent noise. Under normal operating conditions, the water level in the pool remains at least above the minimum level, ensuring the silencer is submerged in most cases. This allows the water to exit from the silencer outlet and then exit below the pool surface, preventing the sudden change in velocity and strong turbulence that occurs with traditional full-pipe pressurized water flow encountering the atmosphere at the outlet. This eliminates turbulent noise to some extent. Additionally, a downward-facing right-angle bend can be installed on the anti-siphon hole 10 for use when the pool is replenished.This design allows the water to flow in a concentrated stream from the right-angle bend outlet downwards and towards the water surface in the pool. This prevents water from spraying outwards from the anti-siphon hole 10, avoiding water impact on the pool wall and thus reducing turbulence noise to some extent.

[0026] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
