Description

Technical Field

[0001] This utility model belongs to the technical field of refrigeration equipment, and in particular relates to a stainless steel muffler connecting pipe with a guide angle. Background Technology

[0002] Stainless steel silencer connectors are key components in refrigeration equipment used to reduce compressor airflow noise and vibration. They absorb and attenuate sound wave energy through a special internal structure (such as perforated plates), ensuring quieter and smoother system operation and extending equipment life. Stainless steel (such as 304 or 316L) is chosen primarily due to its excellent corrosion resistance, resisting the erosion of refrigerants, lubricating oils, and moisture. It also boasts advantages such as high strength, high cleanliness, and long lifespan. However, stainless steel silencer connectors still have the following drawbacks in practical use:

[0003] When assembling the stainless steel silencer pipe before welding, the operator needs to manually align it and carefully insert the pipe. During the insertion process, the amount of movement is limited, and the alignment position needs to be carefully observed, which makes alignment inconvenient.

[0004] Secondly, after assembly, the refrigerant can pass through the muffler. However, the muffler only performs noise reduction on the refrigerant during the noise reduction process, and the noise reduction effect is not high enough. Utility Model Content

[0005] The purpose of this utility model is to provide a stainless steel muffler connector with a guide angle. By setting up a muffler, a guide ring and a connector assembly, the problem of inconvenient alignment of the stainless steel muffler connector and insufficient muffler effect is solved.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a stainless steel muffler connector with a guide angle, comprising a muffler, a guide ring, and a connector assembly. Both ends of the muffler are fixed with air pipes. A guide ring is fixed to the end of the air pipe furthest from the muffler. The air pipe and the guide ring are movably connected to the connector assembly. The connector assembly includes a fixed pipe, a chamfer, and a sound-absorbing cotton sleeve. The fixed pipe is movably connected inside the air pipe. A chamfer is formed on the outer edge of the fixed pipe near the muffler. A sound-absorbing cotton sleeve is fixed to the periphery of the fixed pipe. Air pipes are fixed to both ends of the muffler, and a guide ring is fixed to the outer end of each air pipe. The connector assembly, comprising a fixed pipe, a chamfer, and a sound-absorbing cotton sleeve, is installed inside the air pipe and the guide ring. The fixed pipe is inserted into the air pipe, with a chamfer on the outer side of its inlet end. The outer periphery of the pipe is covered with a sound-absorbing cotton sleeve to reduce noise from the flowing medium.

[0008] Furthermore, a limiting ring is fixed on the inner wall of the air blowing pipe, and a fitting ring is fixed on the outer edge of the limiting ring away from the muffler. The fitting ring is fitted into the chamfer of the fixed pipe. The inner wall of the air blowing pipe is provided with a limiting ring, and the outer edge of the limiting ring has a fitting ring. The fitting ring fits into the chamfer of the fixed pipe, and together with the limiting ring, they constrain the insertion position of the fixed pipe and improve the connection stability.

[0009] Furthermore, a solder ring is movably connected inside the guide ring. The solder ring is movably disposed outside the air blowing pipe. The guide ring contains the solder ring, which is sleeved on the outside of the air blowing pipe. After the fixed pipe is installed in place, the solder ring is welded to seal the connection between the fixed pipe, the air blowing pipe, and the guide ring.

[0010] Furthermore, the connecting pipe assembly also includes a connecting groove and a limiting plate. The connecting groove is arranged in a ring array on the periphery of the fixed pipe near the muffler. The limiting plate is fixed on the periphery of the fixed pipe away from the muffler. The solder ring is disposed between the guide ring and the limiting plate. The connecting groove is arranged in a ring array on the periphery of the fixed pipe near the muffler to avoid stress concentration. The limiting plate is provided on the outside of the guide ring. The solder ring is clamped between the guide ring and the limiting plate to achieve a reliable seal during welding.

[0011] Furthermore, the connecting pipe assembly also includes an installation connector. One end of the sound-absorbing cotton sleeve near the muffler is fixed to the end of the limiting plate, and the other end of the fixing pipe away from the muffler is fixedly connected to the installation connector. One end of the sound-absorbing cotton sleeve is fixed to the end of the limiting plate, and the other end of the fixing pipe is connected to the installation connector for connecting to an external pipeline.

[0012] Furthermore, the connecting pipe assembly also includes a welding port and a conveying pipe. Each of the mounting joints has a welding port welded and fixed inside. The end of the welding port away from the fixed pipe is fixedly connected to the conveying pipe. Each mounting joint has a welding port welded inside. The welding port is connected to the conveying pipe. The cooling medium flows into the silencer through the conveying pipe, the welding port, and the fixed pipe. After the noise is silenced, it flows out in the reverse direction. The sound-absorbing cotton sleeve further absorbs the flowing noise.

[0013] This utility model has the following beneficial effects:

[0014] This invention solves the problem of inconvenient alignment of stainless steel muffler connectors by setting up a muffler, guide ring, and connector assembly. Before inserting the fixed tube into the guide ring, the solder ring is put on the end of the fixed tube, and then the chamfer on the fixed tube is inserted into the guide ring and guided into the air pipe through the guide ring. At this time, the chamfer on the fixed tube is locked onto the fitting ring, and the position is restricted by the limiting ring, making it easier to align the stainless steel muffler connectors during operation.

[0015] This invention solves the problem of insufficient noise reduction in stainless steel silencer connectors by incorporating a silencer, guide ring, and connector assembly. Cooling medium is transported through a delivery pipe to the weld joint, then through the weld joint to a fixed pipe, then through the fixed pipe to an air blowing pipe, and finally through the air blowing pipe to the silencer for noise reduction. It is then transported to another air blowing pipe, through the air blowing pipe to the fixed pipe, and after passing through the fixed pipe, it is transported back to the weld joint and then to the delivery pipe, finally being output to subsequent equipment. As the cooling medium flows through the sound-absorbing cotton sleeve surrounding the fixed pipe, the sound-absorbing cotton sleeve absorbs the noise generated in the cooling medium within the fixed pipe, further reducing the noise generated during the flow of the cooling medium, thus improving the noise reduction effect of the stainless steel silencer connector.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Specific Implementation Example 1

[0025] Please see Figure 1-5 This utility model relates to a stainless steel muffler connector with a guide angle, comprising a muffler 1, a guide ring 2, and a connector assembly 3. Both ends of the muffler 1 are fixed with air blowing pipes 101. During operation, the muffler 1 silences the air supplied by the connector assembly 3. The connector assembly 3 is connected to the air blowing pipes 101. A guide ring 2 is fixed to the end of the air blowing pipe 101 furthest from the muffler 1. The guide ring 2 guides the structure of the fixed pipe 301 into the air blowing pipe 101. The connector assembly 3 is movably connected to both the air blowing pipe 101 and the guide ring 2. Component 3 includes a fixed tube 301, a chamfer 302, and a sound-absorbing cotton sleeve 305. The fixed tube 301 is movably connected inside the air blowing pipe 101. A chamfer 302 is provided on the outer edge of the fixed tube 301 near the muffler 1. The sound-absorbing cotton sleeve 305 is fixed around the fixed tube 301. The fixed tube 301 transports the cooling medium in and out of the muffler 1. The chamfer 302 increases the stability of cooling after the fixed tube 301 enters the air blowing pipe 101. The fixed tube 301 absorbs the noise generated by the medium passing through it through the sound-absorbing cotton sleeve 305.

[0026] Specifically, a limiting ring 102 is fixed on the inner wall of the air blowing pipe 101. A fitting ring 103 is fixed on the outer edge of the limiting ring 102 away from the muffler 1. The fitting ring 103 is fitted and connected to the chamfer 302 of the fixed pipe 301. The air blowing pipe 101 restricts the position of the fixed pipe 301 through the limiting ring 102 and is fitted at the chamfer 302 of the fixed pipe 301 through the fitting ring 103. After the fixed pipe 301 and the limiting ring 102 abut against each other, the position of the limiting ring 102 is restricted.

[0027] Furthermore, a solder ring 201 is movably connected inside the guide ring 2. The solder ring 201 is movably disposed on the outside of the air blowing pipe 101, and the guide ring 2 is disposed therein via the solder ring 201, with the solder ring 201 being fitted into it.

[0028] The operation process of this embodiment is as follows: Before the fixed tube 301 needs to be inserted into the guide ring 2, the solder ring 201 is put on the end of the fixed tube 301, and then the chamfer 302 on the fixed tube 301 is inserted into the guide ring 2 and guided into the air blowing tube 101 through the guide ring 2. At this time, the chamfer 302 on the fixed tube 301 is stuck on the fitting ring 103 and the position is restricted by the limiting ring 102 until the solder ring 201 is stuck on the guide ring 2. Then welding is performed. During welding, the fixed tube 301, the air blowing tube 101 and the guide ring 2 are welded and set by the solder ring 201, so that the gap between the air blowing tube 101 and the fixed tube 301 is sealed. Specific Implementation Example 2

[0029] Please see Figure 1-5 Based on the first specific embodiment, the pipe assembly 3 further includes a connecting groove 303 and a limiting plate 304. The connecting groove 303 is arranged in a ring array on the periphery of the fixed pipe 301 near the muffler 1. The limiting plate 304 is fixed on the periphery of the fixed pipe 301 away from the muffler 1. The solder ring 201 is disposed between the guide ring 2 and the limiting plate 304. The fixed pipe 301 is prevented from pressure concentration by the connecting groove 303. The solder ring 201 is disposed between the guide ring 2 and the limiting plate 304. During welding, the guide solder and the limiting plate 304 are welded together to ensure that the gap between the air blowing pipe 101 and the fixed pipe 301 is sealed.

[0030] Specifically, the pipe assembly 3 also includes an installation connector 306, a sound-absorbing cotton sleeve 305 with one end near the muffler 1 fixed to the end of the limiting plate 304, and a fixed pipe 301 with the installation connector 306 fixedly connected to the end away from the muffler 1. The sound-absorbing cotton sleeve 305 absorbs the noise generated by the cooling medium passing through the fixed pipe 301, and the installation connector 306 connects to the welding joint 307.

[0031] Furthermore, the connecting pipe assembly 3 also includes a welding port 307 and a delivery pipe 308. Each mounting joint 306 has a welding port 307 welded and fixed inside. The end of the welding port 307 away from the fixed pipe 301 is fixedly connected to the delivery pipe 308. The mounting joint 306 is welded and fixed inside through the welding port 307. The ends of the two delivery pipes 308 away from the welding port 307 are respectively connected to the equipment for inputting and outputting cooling medium, so that the cooling medium passes through the silencer 1.

[0032] The operation process of this embodiment is as follows: During operation, the cooling medium is transported to the welding port 307 through a conveying pipe 308, then to the fixed pipe 301 through the welding port 307, then to the air blowing pipe 101 through the fixed pipe 301, and then to the silencer 1 for noise reduction treatment in the air blowing pipe 101. It is then transported to another air blowing pipe 101, and then to the fixed pipe 301 through the air blowing pipe 101. After passing through the fixed pipe 301, it is transported to the welding port 307 and then to the conveying pipe 308, and finally output to the subsequent equipment. When the cooling medium flows through the sound-absorbing cotton sleeve 305 around the fixed pipe 301, the sound-absorbing cotton sleeve 305 absorbs the noise generated in the cooling medium in the fixed pipe 301, further reducing the noise generated in the flow of the cooling medium.
