Description

Technical Field

[0001] This application relates to the technical field of condensate drain valves with water traps, and in particular to a multi-model compatible condensate drain valve with water traps. Background Technology

[0002] Condensate traps are commonly used in air conditioning, HVAC systems, or other equipment that involves condensate drainage. Their function is to remove accumulated condensate from the system to maintain normal equipment operation and prevent potential problems caused by moisture buildup.

[0003] Existing technologies, such as the utility model patent with publication number CN220888845U, disclose a water trap fitting and piping system. The disclosed water trap fitting includes an interconnected crescent-shaped body and a water trap main body. The radius of curvature of the crescent-shaped body is 4 to 10 times its outer diameter. The end of the crescent-shaped body away from the water trap main body is the inlet, and the end of the water trap main body away from the crescent-shaped body is the outlet. The water trap main body consists of an interconnected straight pipe section and a curved section. One end of the straight pipe section is connected to the crescent-shaped body and is tangent to the inner arc of the crescent-shaped body. The end of the straight pipe section away from the crescent-shaped body is connected to the curved section. The bending direction of the crescent-shaped body is opposite to the bending direction of the curved section. The disclosed piping system includes the aforementioned water trap fitting. This water trap fitting is convenient to install at corner locations, has low construction difficulty, and is widely applicable.

[0004] The inventor discovered through daily use that existing air conditioner condensate drain traps (also known as "water traps" or "U-shaped bends") are simple devices that prevent backflow of air, odor intrusion, and insect entry through a water seal principle. Their core principle and design focus are primarily the water seal principle and the anti-backflow mechanism. Drain traps are typically designed as U-shaped or S-shaped pipes, with a certain amount of condensate continuously stored inside, forming a sealed barrier. When the air conditioner is running, the condensate produced by the evaporator flows into the drain trap and accumulates at the bottom of the U-shape, blocking direct communication between the drain pipe and the outside air. However, due to the different sizes of the connecting pipes, the dimensions of the connecting pipes need to be redesigned according to site requirements during installation, which can significantly impact the on-site construction progress. Utility Model Content

[0005] One of the technical problems this application aims to solve is the disadvantage that bends are difficult to connect with various types of pipes.

[0006] To address the aforementioned technical problems, this application provides a multi-model compatible condensate drain valve for water traps, comprising:

[0007] The bend has a multi-stage connector fixedly connected inside one end.

[0008] Connecting pipe, the connecting pipe is slidably connected to the multi-stage connector; and

[0009] The connecting structure is set on the arc surface of the bend;

[0010] The connecting structure includes a threaded ring, which is rotatably connected to a bent pipe. A fixed ring is slidably connected to one end of the bent pipe near the threaded ring, and the fixed ring is threadedly connected to the threaded ring. A stop ring is fixedly connected to the inner wall of the connecting pipe, and the stop ring is slidably connected to the fixed ring. Several limiting rods are fixedly connected to the arc surface of the bent pipe near the threaded ring. A slip ring is slidably connected to the arc surface of the bent pipe near the limiting rods. Several limiting grooves are opened on the inner wall of the slip ring, and the limiting grooves are slidably connected to the limiting rods. Several insert rods are fixedly connected to one side of the slip ring near the threaded ring. Several insertion holes are opened on the side of the threaded ring near the insert rods, and the insert rods are adapted to the insertion holes. A rotating ring is rotatably connected to the inner wall of the threaded ring near the slip ring. A spring is provided between the rotating ring and the slip ring, and the two ends of the spring are fixedly connected to the rotating ring and the slip ring respectively. The spring is sleeved on the arc surface of the bent pipe. A multi-stage connecting gasket is interference-fitted to the inner wall of the multi-stage connector, and the multi-stage connecting gasket is interference-fitted to the connecting pipe.

[0011] The aforementioned components achieve the following effect: When connecting the connecting pipe and the bend, first pull the fixing ring to move it, placing the fixing ring on the arc surface of the connecting pipe. Then, pull the fixing ring towards one end of the connecting pipe to bring the fixing ring and the abutment ring into contact. Next, pull the connecting pipe to move it, aligning the fixing ring with the bend. Then, place the multi-stage connecting gasket on the connecting pipe, insert the fixing ring into the bend, and pull the sliding ring to move it. The sliding ring causes the limiting groove to slide on the arc surface of the limiting rod, and the sliding ring causes the insertion rod to move. The insertion rod is separated from the insertion hole, then the slip ring drives the spring to stretch, and the threaded ring is rotated to move. The rotating ring rotates on the inner wall of the threaded ring, and the threaded ring drives the fixed ring to move. The fixed ring drives the abutment ring to move, and the abutment ring drives the connecting tube to rub into the multi-stage connector. Then the multi-stage connecting gasket is connected to the multi-stage connector for sealing. After the fixing is completed, the slip ring spring is released to retract and drive the slip ring to reset. The slip ring drives the insertion rod to be inserted into the appropriate insertion hole for fixing. Then the connecting tube and the bend are connected for use.

[0012] In some embodiments, a plurality of levers are fixedly connected to the arc surface of the threaded ring, and the plurality of levers are evenly distributed on the threaded ring.

[0013] The effect achieved by the above components is that when it is necessary to rotate the threaded ring, the lever can be rotated directly, and the lever drives the threaded ring to move, making it more convenient to rotate the threaded ring.

[0014] In some embodiments, the arc surface of the slip ring is provided with a plurality of slots, which are evenly distributed on the slip ring.

[0015] The effect achieved by the above components is that the groove can increase the friction between the hand and the slip ring, preventing slippage when the slip ring is pulled.

[0016] In some embodiments, the cross-section of the multi-level connecting pad is stair-shaped, and the multi-level connecting pad is a rubber pad.

[0017] The effects achieved by the above components are: the rubber material not only has excellent plasticity, but can also seal between the connecting pipe and the multi-stage connector, and can also increase the friction between the connecting pipe and the connector.

[0018] In some embodiments, a plurality of limiting rods are evenly distributed on the bend, and the limiting rods are stainless steel rods.

[0019] The effect achieved by the above components is that the limiting rod can limit the slip ring and prevent it from rotating during use.

[0020] In some embodiments, the cross-section of the swivel ring is annular, and the swivel ring is a stainless steel ring.

[0021] The effect achieved by the above components is that the stainless steel material can increase the service life of the swivel ring and prevent it from rusting during use.

[0022] In some embodiments, the retaining ring is made of plastic and has a circular cross-section.

[0023] The effects achieved by the above components are: firstly, the cost of plastic materials is reduced, which can greatly reduce the manufacturing cost of the retaining ring; secondly, it can prevent the retaining ring from rusting during use.

[0024] Through the above technical solution, the existing air conditioning condensate drain bend (also known as a "water trap" or "U-bend") provided in this application, by setting a connection structure, is a simple device that prevents air backflow, odor intrusion, and insect entry through the water seal principle. Its core principle and design points are mainly the water seal principle and the anti-backflow mechanism. The drain bend is usually designed as a U-shaped or S-shaped pipe, with a certain amount of condensate water stored inside for a long time, forming a sealed barrier liquid. When the air conditioner is running, the condensate water produced by the evaporator flows into the drain bend and accumulates at the bottom of the U-shape, blocking the direct connection between the drain pipe and the outside air. Because the connecting pipes have different sizes, the size of the connecting pipes needs to be redesigned according to the site requirements during installation, which greatly affects the on-site construction progress. This device improves the water trap valve, adapting to different types of drain outlets, and allows for quick installation and disassembly of the bend pipe and external pipes, greatly improving the efficiency of bend pipe connection and avoiding damage to the bend pipe caused by violent disassembly.

[0034] Please see Figures 1 to 5 This utility model provides a technical solution: a multi-model compatible water trap condensate drain valve, comprising:

[0035] Bend 1, with a multi-stage connector 3 fixedly connected inside one end of bend 1;

[0036] Connecting pipe 2, which is slidably connected to multi-stage connector 3; and

[0037] Connection structure 4 is set on the arc surface of the bend 1.

[0038] In the embodiments of this utility model, please refer to Figures 1 to 5The connecting structure 4 includes a threaded ring 402, which is rotatably connected to the bend 1. A fixed ring 404 is slidably connected to one end of the bend 1 near the threaded ring 402, and the fixed ring 404 is threadedly connected to the threaded ring 402. A stop ring 409 is fixedly connected to the inner wall of the connecting pipe 2, and the stop ring 409 is slidably connected to the fixed ring 404. Several limiting rods 405 are fixedly connected to the arc surface of the bend 1 near the threaded ring 402. A sliding ring 406 is slidably connected to the arc surface of the bend 1 near the limiting rods 405. Several limiting grooves 410 are formed on the inner wall of the sliding ring 406, and the limiting grooves 410 are slidably connected to the limiting rods 405. A number of insert rods 412 are fixedly connected to the side of the slip ring 406 near the threaded ring 402. A number of insertion holes 403 are opened on the side of the threaded ring 402 near the insert rods 412. The insert rods 412 are adapted to the insertion holes 403. A rotating ring 413 is rotatably connected to the inner wall of the threaded ring 402 near the end of the slip ring 406. A spring 411 is provided between the rotating ring 413 and the slip ring 406. The two ends of the spring 411 are fixedly connected to the rotating ring 413 and the slip ring 406 respectively. The spring 411 is sleeved on the arc surface of the bend 1. A multi-stage connecting pad 408 is interference-fitted to the inner wall of the multi-stage connector 3. The multi-stage connecting pad 408 is interference-fitted to the connecting pipe 2. When connecting the connecting pipe 2 to the bend 1, first pull the fixing ring 404 to move it, placing the fixing ring 404 on the arc surface of the connecting pipe 2. Then, pull the fixing ring 404 towards one end of the connecting pipe 2 to abut the fixing ring 404 and the abutment ring 409. Next, pull the connecting pipe 2 to move it, aligning the fixing ring 404 with the bend 1. Then, place the multi-stage connecting pad 408 on the connecting pipe 2, and insert the fixing ring 404 into the bend 1. Pull the sliding ring 406 to move it, causing the limiting groove 410 to slide on the arc surface of the limiting rod 405. The sliding ring 406 also causes the insertion rod 412 to move, separating it from the insertion hole 403. Finally, the sliding ring 406 pulls the spring 411. Extend and rotate the threaded ring 402 to move it. The rotating ring 413 rotates on the inner wall of the threaded ring 402. The threaded ring 402 drives the fixed ring 404 to move. The fixed ring 404 drives the abutment ring 409 to move. The abutment ring 409 drives the connecting tube 2 to rub into the multi-stage connector 3. Then the multi-stage connecting gasket 408 is connected to the multi-stage connector 3 for sealing. After fixing, the slip ring 406 is released and the spring 411 is contracted to drive the slip ring 406 to reset. The slip ring 406 drives the insertion rod 412 to be inserted into the appropriate insertion hole 403 for fixing. Then the connecting tube 2 and the bend tube 1 are connected for use. Several handles 401 are fixedly connected to the arc surface of the threaded ring 402. Several handles 401 are evenly distributed on the threaded ring 402.When it is necessary to rotate the threaded ring 402, the handle 401 can be rotated directly. The handle 401 drives the threaded ring 402 to move, making it easier to rotate the threaded ring 402. The arc surface of the slip ring 406 has several grooves 407, which are evenly distributed on the slip ring 406. The grooves 407 can increase the friction between the hand and the slip ring 406, preventing slippage when pulling the slip ring 406. The multi-stage connecting pad 408 has a stair-shaped cross-section and is made of rubber. The rubber material not only has excellent plasticity but can also seal between the connecting pipe 2 and the multi-stage connector 3 and increase the friction between the connecting pipe 2 and the connector. Several limiting rods 405 are evenly distributed on the bend 1, and the limiting rods 405 are made of stainless steel. The limiting rod 405 can limit the movement of the slip ring 406, preventing it from rotating during use. The rotating ring 413 has a circular cross-section and is made of stainless steel. The stainless steel material increases the service life of the rotating ring 413 and prevents it from corroding during use. The fixing ring 404 is made of plastic and also has a circular cross-section. Firstly, the lower cost of the plastic material significantly reduces the manufacturing cost of the fixing ring 404; secondly, it prevents the fixing ring 404 from corroding during use.

[0039] Working principle: When connecting the connecting pipe 2 and the bend 1, first pull the fixing ring 404 to move it, so that the fixing ring 404 is placed on the arc surface of the connecting pipe 2. Then, pull the fixing ring 404 towards one end of the connecting pipe 2 to make the fixing ring 404 and the abutment ring 409 abut against each other. Then, pull the connecting pipe 2 to move it, so that the connecting pipe 2 drives the fixing ring 404 to align with the bend 1. Then, put the multi-stage connecting pad 408 on the connecting pipe 2. Then, insert the fixing ring 404 into the bend 1. Pull the sliding ring 406 to move it, so that the sliding ring 406 drives the limiting groove 410. The limit rod 405 slides on its arc surface, and the slip ring 406 drives the insertion rod 412 to move, separating the insertion rod 412 from the insertion hole 403. Then, the slip ring 406 drives the spring 411 to stretch, rotating the threaded ring 402 to move. The rotating ring 413 rotates on the inner wall of the threaded ring 402, and the threaded ring 402 drives the fixed ring 404 to move. The fixed ring 404 drives the abutment ring 409 to move, and the abutment ring 409 drives the connecting tube 2 to rub into the multi-stage connector 3. Then, the multi-stage connecting pad 408 connects with the multi-stage connector 3 to form a tight seal. After sealing and fixing, release the spring 411 of the slip ring 406 to retract it, causing the slip ring 406 to return to its original position. The slip ring 406 then drives the insertion rod 412 to be inserted into the appropriate insertion hole 403 for fixing. Then, connect the connecting pipe 2 and the bend pipe 1 for use. When it is necessary to rotate the threaded ring 402, the handle 401 can be rotated directly. The handle 401 drives the threaded ring 402 to move, making it easier to rotate the threaded ring 402. The groove 407 increases the friction between the hand and the slip ring 406, preventing slippage when pulling the slip ring 406. The rubber material not only has excellent plasticity, but can also seal between the connecting pipe 2 and the multi-stage connector 3, and can also increase the friction between the connecting pipe 2 and the connector. The limiting rod 405 can limit the slip ring 406 to prevent the slip ring 406 from rotating during use. The stainless steel material can increase the service life of the rotating ring 413 and prevent the rotating ring 413 from rusting during use. First, the cost of the plastic material is reduced, which can greatly reduce the manufacturing cost of the fixed ring 404. Second, it can prevent the fixed ring 404 from rusting during use.
