[0029] A flange silencer interface, such as Figure 1-Figure 3As shown, it includes a flange 10, and a muffler inner pipe 20 that is compatible with the size of the external pipe and plug-fitted is installed at the center of the flange 10; the muffler inner pipe 20 is threadedly connected to the flange 10; the muffler inner pipe 20 includes a metal substrate layer 201, and a muffler and sound insulation layer 202 is installed inside the metal substrate layer 201, and an anti-corrosion inner layer 203 is arranged on the inner wall of the muffler and sound insulation layer 202, and a sealing outer layer 204 is arranged on the outer wall of the metal substrate layer 201. By setting the muffler and sound insulation layer 202, the interface can effectively reduce the noise generated when the fluid flows in the pipeline. Noise can be reduced and good noise reduction effect can be provided. The setting of the anti-corrosion inner layer 203 enables the inner wall of the silencer inner tube 20 to effectively resist the corrosive substances in the fluid and prolong the service life of the silencer inner tube. At the same time, it also ensures the purity of the fluid and prevents possible secondary pollution. The threaded connection between the silencer inner tube 20 and the flange 10 makes installation and disassembly convenient and quick, greatly improving work efficiency. The sealing outer layer 204 is on the outer wall of the metal substrate layer 201, which enhances the sealing performance of the flange silencer interface, effectively prevents fluid leakage, and ensures the safe operation of the pipeline system.

[0030] Furthermore, the flange 10 is provided with a plurality of connection screw holes 11 which are evenly and equidistantly arranged in a ring shape, so that the interface can be easily fixedly connected to other parts of the pipeline system.

[0031] Among them, an internal threaded connecting ring seat 12 for connecting the silencer inner pipe 20 is arranged at the center of the flange 10. The internal threaded connecting ring seat 12 and the flange 10 are an integrally formed structure. An external threaded connecting head 21 which is matched with the size of the internal threaded connecting ring seat 12 and is threadedly connected is arranged in the middle of the outer wall of the silencer inner pipe 20, which not only ensures the tightness of the connection, but also improves the reliability and durability of the connection. Since the internal threaded connecting ring seat 12 and the flange 10 are an integrally formed structure, the entire interface is more sturdy and durable.

[0032] Specifically, the metal substrate layer 201 is made of seamless steel pipe, galvanized pipe or alloy pipe, and has a thickness of 2-4mm. It has high strength and corrosion resistance, and can ensure that the silencer inner pipe 20 is not easily deformed or damaged during use. The silencer and sound insulation layer 201 is made of glass fiber, sound-absorbing cotton, polyethylene foam, rock wool or mineral wool, and has a thickness of 3-10mm. It has good sound absorption performance and can effectively reduce the noise generated when the fluid flows.

[0033] In addition, the anti-corrosion inner layer 203 adopts polyurethane anti-corrosion coating, epoxy resin anti-corrosion coating or acrylic paint, has good anti-corrosion performance, can resist the erosion of the inner wall of the silencer inner pipe by corrosive substances in the fluid, and has a thickness of 0.5-1.5mm. The sealing outer layer 204 is made of wear-resistant rubber or latex material, and has a thickness of 1-2mm. It has good elasticity and wear resistance, and can ensure the sealing performance between the silencer inner pipe and the flange.

[0034] Working principle of this flange silencer interface:

[0035] Metal substrate layer 201: As the skeleton of the sound-absorbing inner tube 20, the metal substrate layer 201 provides the necessary mechanical strength and stability. At the same time, it also provides support for the internal sound-absorbing and sound-insulating layer 202.

[0036] Noise-absorbing and sound-insulating layer 202: This is the key part to achieve the noise-absorbing function. The noise-absorbing and sound-insulating layer 202 uses special materials or structural designs, such as porous materials, sound wave absorbing structures, etc., which can effectively absorb or reflect the sound waves generated when the fluid flows, thereby reducing the propagation of noise. When the fluid flows in the pipeline, the sound waves generated will be captured by the noise-absorbing and sound-insulating layer 202 and converted into heat energy or other forms of energy, thereby achieving the noise-absorbing effect.

[0037] Anti-corrosion inner layer 203: The anti-corrosion inner layer 203 covers the inner wall of the sound-absorbing and sound-insulating layer 202. It is made of corrosion-resistant materials and can resist corrosive substances that may exist in the fluid. This can not only extend the service life of the sound-absorbing inner tube 20, but also prevent the fluid from being contaminated and ensure the purity of the fluid.

[0038] Sealing outer layer 204: The sealing outer layer 204 is located on the outer wall of the metal substrate layer 201, and it enhances the sealing performance of the flange muffler interface. Through tight fitting and connection, the sealing outer layer 204 can effectively prevent fluid leakage and ensure the safe operation of the pipeline system.

[0039] The introduction of this flange silencer interface technology effectively reduces the noise level in the pipeline system through the built-in silencer and sound insulation layer. After testing, the flange interface using this technology can reduce the noise level to the normal level during operation, significantly improving the working environment.
