Description

Technical Field

[0001] This utility model relates to the field of steam trap technology, specifically a steam trap. Background Technology

[0002] The main functions of a steam trap include automatically removing condensate and non-condensable gases such as air from heating equipment or steam pipelines, preventing steam leakage, protecting equipment safety, and saving energy; timely removing accumulated water from pipelines to prevent water accumulation from affecting equipment operation and ensuring safe operation; preventing water hammer, vibration, and freezing cracking; and preventing condensate from corroding equipment and preventing water hammer, vibration, and freezing cracking in steam pipelines. A steam trap is needed to avoid steam loss during use.

[0003] Upon investigation, it was found that existing steam traps have filters located inside the valve body. Disassembling the filter plate requires isolating, depressurizing, and cooling the entire valve, which is a lengthy process and prone to burns, mechanical damage, or seal failure due to improper operation. Furthermore, if condensate is not completely drained or steam pressure is not released during disassembly, high-speed steam may impact the pipeline, causing water hammer, pipeline deformation, or rupture, which will prolong downtime for maintenance and increase labor costs. In response to the above issues, technological innovation will be carried out on the basis of existing devices. Utility Model Content

[0012] Preferably, both sides of the sweeping rod are fixedly connected to a corrugated tube that is movably sleeved on the threaded rod, and the end of the corrugated tube away from the sweeping rod is fixedly connected to the inner wall of the transmission groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. This steam trap has a fixed block fixedly connected to the surface of the delivery pipe. The fixed block has a placement groove inside, and a filter plate slides inside the placement groove. Placing the filter plate in the delivery pipe can directly intercept impurities carried in the steam, preventing them from entering the valve cavity and causing blockage or wear on key components. This effectively prevents impurities from interfering with the opening and closing of the steam trap, reduces the risk of failure caused by impurity accumulation, and allows for individual cleaning or replacement without disassembling the entire valve, shortening the maintenance cycle.

[0014] 2. This steam trap has a motor fixedly connected to one side of a fixed block. A threaded rod is rotatably connected inside the fixed block, and a cleaning rod is threadedly connected to the surface of the threaded rod. The cleaning rod scrapes the surface of the filter plate, actively removing the impurities accumulated on the filter plate surface. This avoids localized corrosion caused by long-term retention of impurities, avoids the cumbersome process of traditional manual cleaning, prevents filter plate clogging, and ensures stable drainage.

[0017] Please see Figures 1-5 This utility model provides a technical solution: a steam trap, including a valve body 1. The valve body 1 has an existing structure, which will not be described in detail here. A conveying pipe 2 is fixedly connected to one side of the valve body 1. A fixing block 3 is fixedly connected to the surface of the conveying pipe 2. A placement groove 4 is opened inside the fixing block 3. A filter plate 5 is slidably connected inside the placement groove 4. The surface of the filter plate 5 has filter holes for filtering impurities, which can intercept the conveyed impurities. A side frame 6 is fixedly connected to one side of the filter plate 5. The filter plate 5 slides in the placement groove 4 by moving the side frame 6. A fixing plate 7 is fixedly connected to one side of the fixing block 3. A sliding groove 8 is opened inside the fixing plate 7. An L-shaped rod 9 is slidably connected inside the sliding groove 8. The L-shaped rod 9 can cover the side frame 6 to prevent gas and water leakage. A spring 10 is fixedly connected inside the sliding groove 8. The side of the spring 10 near the L-shaped rod 9 is connected to... The L-shaped rod 9 is fixedly connected to the surface. The movement of the L-shaped rod 9 drives the compression and reset of the spring 10. The slide groove 8 is equipped with a rotating gear 11. One end of the gear 11 rotates through the interior of the fixed plate 7 and extends to the exterior of the fixed plate 7. The side of the L-shaped rod 9 near the gear 11 is provided with teeth. One side of the L-shaped rod 9 is connected to the surface of the gear 11 through tooth meshing. When the operator needs to remove the filter plate 5, the rotating rod 12 is rotated to make the gear 11 move through the teeth on the surface, and at the same time, the spring 10 is compressed, so that the L-shaped rod 9 releases the pressure on the side frame 6. Then the side frame 6 is pulled out, and the filter plate 5 slides out of the placement groove 4 for replacement. After the new filter plate 5 is slid back into the placement groove 4, the rotating rod 12 is released, the spring 10 is reset, and the L-shaped rod 9 is pressed back onto the surface of the side frame 6 to prevent gas and water leakage.

[0018] The fixed block 3 has a transmission groove 14 inside, and a threaded rod 15 is rotatably connected inside the transmission groove 14. A motor 13 is fixedly connected to one side of the fixed block 3, and the output end of the motor 13 is fixedly connected to one end of the threaded rod 15. A cleaning rod 17 is slidably connected inside the transmission groove 14. The cleaning rod 17 can clean impurities on the surface of the filter plate 5 to prevent impurities from clogging the filter plate 5 and affecting its normal drainage function. The inside of the cleaning rod 17 is threadedly connected to the surface of the threaded rod 15, and movable sleeves are fixedly connected to both sides of the cleaning rod 17. The bellows 16 on the threaded rod 15 has one end away from the cleaning rod 17 that is fixedly connected to the inner wall of the transmission groove 14. The bellows 16 can prevent water and impurities from entering the interior and causing damage to the machine. When the operator needs to clean the impurities on the surface of the filter plate 5, the motor 13 is started to move the threaded rod 15 to drive the cleaning rod 17 on the surface, so that the cleaning rod 17 can clean the impurities on the surface of the filter plate 5 and prevent blockage. At the same time, the bellows 16 on the surface of the threaded rod 15 can prevent water and impurities from entering and causing damage to the machine.

[0019] Working principle: For this type of steam trap, the valve body 1 is installed inside the steam pipeline. A float is installed inside the valve body 1. Steam enters the valve body 1 from the delivery pipe 2 and the fixing block 3. When a certain amount of condensate and non-condensable gases accumulate inside the valve body 1, the float is immersed in the liquid and floats due to buoyancy. When the float reaches a certain height, the rod connected to the float will open the valve. This is existing technology and will not be elaborated further. When the operator needs to remove the filter plate 5, they rotate the rotating rod 12. The gear 11 drives the L-shaped rod 9 to move through the teeth on its surface, while simultaneously compressing the spring 10. This releases the L-shaped rod 9 from the pressure on the side frame 6, allowing the side frame 6 to be pulled out. This causes the filter plate 5 to slide out of the placement groove 4 for replacement. After the new filter plate 5 is slid back into the placement groove 4, the rotating rod 12 is released, allowing the spring 10 to return to its original position. This causes the L-shaped rod 9 to press back onto the surface of the side frame 6, preventing gas and water leakage. Replacing the filter plate 5 reduces the risk of malfunctions caused by impurity buildup. Furthermore, it allows for individual cleaning or replacement without disassembling the entire valve, shortening the maintenance cycle.

[0020] When the operator needs to clean the impurities on the surface of the filter plate 5, the motor 13 is started, which causes the threaded rod 15 to move the cleaning rod 17 on the surface. The cleaning rod 17 can clean the impurities on the surface of the filter plate 5 to prevent clogging. At the same time, the corrugated pipe 16 on the surface of the threaded rod 15 can prevent water and impurities from entering and causing damage to the machine. By scraping the surface of the filter plate 5, the impurities accumulated on the surface of the filter plate 5 are actively removed, while avoiding local corrosion caused by long-term retention of impurities. This avoids the cumbersome process of traditional manual cleaning, prevents the filter plate 5 from clogging, and ensures stable drainage.
