Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline connectors, and in particular relates to a PE pipe connecting component. Background Art

[0002] PE materials are widely used in the field of water supply pipe manufacturing due to their high strength, corrosion resistance, and non-toxicity. Because their material will not rust, they are ideal pipes to replace ordinary iron water supply pipes. Pipe connectors are usually required when connecting two PE pipes. Flanges are a common way to connect PE pipes. The flanges are welded or hot-melt connected at the ends of the PE pipes, and then the two flanges are connected together by bolts. They are suitable for occasions that require frequent disassembly, such as pipeline maintenance and equipment connection. While PE pipes are transmitting water, impurities in the water behind the water transmission route sometimes accumulate and become clogged, requiring staff to regularly disassemble and clean the PE pipes. However, this method is more cumbersome, time-consuming, labor-intensive, and inefficient. In addition, when the pipe is disconnected, the waterway needs to be suspended, which interferes with the water delivery work. Utility Model Content

[0018] See also Figure 1-Figure 4 The utility model provides the following technical solution: it includes two PE pipes 1, a two-way pipe 2 is arranged between the two PE pipes 1, and both ends of the two-way pipe 2 are rotatably connected with a rotating connecting pipe 21. The two rotating connecting pipes 21 are connected to the corresponding PE pipe 1 through flanges. Two water troughs 22 are provided in the two-way pipe 2, and an inner connecting pipe 211 is installed on the inner side of the two rotating connecting pipes 21. The inner connecting pipe 211 is rotatably connected to the inner wall of the two-way pipe 2. A water hole 212 is provided on one side of the inner connecting pipe 211. Four connecting holes 23 are provided in the two-way pipe 2. The water trough 22 is connected to the internal space of the two water holes 212 through the corresponding two connecting holes 23. The opening directions of the two water holes 212 correspond to each other. A card slot 24 is provided on one side of the PE pipe 1, and a sealing plate 25 is hinged in the card slot 24. A filter cup 3 is installed on one side of the sealing plate 25, and the filter cup 3 is snap-connected to the inner wall of the corresponding water trough 22.

[0019] In this embodiment: the two-way pipe 2 supports and protects the various components of the device externally, and the two rotating connecting pipes 21 rotate at the two ends of the two-way pipe 2. The rotating connecting pipe 21 is connected and fixed to the flange at the end of the PE pipe 1 through its own flange, so that the two PE pipes 1 can complete the docking and water flow. The two-way pipe 2 realizes two water flow channels through two water grooves 22, and the two water grooves 22 are different from each other, so that the two water grooves 22 can work independently. The rotating connecting pipe 21 passes water between the inner connecting pipe 211 and the two-way pipe 2, and the inner connecting pipe 211 realizes the waterway opening through the water hole 212. When the water groove 22 is aligned with the water hole 212 through the connecting hole 23, the waterway flows. The four connecting holes 23 are divided into two groups. By rotating the two-way pipe 2, the two groups of connecting holes 23 can be alternately docked with the two water holes 212, thereby allowing the two water grooves 22 to The filter cup 3 is then removed and cleaned, so that the water channel does not need to be disconnected when cleaning the filter cup 3, thereby avoiding affecting the water use, and there is no need to disassemble the two pipes and connecting components, which is simple and convenient to operate, saving time and effort, and improving efficiency.

[0020] One-way valves 221 are installed on the inner walls of the two water troughs 22, and the filter cup 3 does not contact the one-way valves 221; the one-way valves 221 intercept the water source in the water troughs 22 to prevent the impurities intercepted and filtered at the filter cups 3 from flowing back into the upstream pipeline, which is convenient for centralized cleaning of impurities, and the operations of the water troughs 22 and the filter cups 3 will not interfere with each other.

[0021] An inner filter tube 31 is installed on the inner side of the bottom of the filter cup 3, and the inner filter tube 31 is flush with the top of the filter cup 3; the inner filter tube 31 and the filter cup 3 participate in the filtering and impurity removal work together. The inner filter tube 31 increases the filtering area inside the filter cup 3, thereby increasing the spatial range for filtering impurities, making it easier to increase the filtering reserve and reduce the occurrence of blockage.

[0022] The cam 33 is pressed against the top of the bottle 32 and the bottle 33, and the cam 33 is pressed against the bottle 32 to prevent it from sliding into the bottle 32. When the cam 33 is in the closed position, the bottle 33 is in a closed position.

[0023] A rectangular ring sealing strip 251 is installed on the inner side of the sealing plate 25, and the rectangular ring sealing strip 251 contacts the inner wall of the card slot 24; when the sealing plate 25 is closed, the sealing plate 25 drives the rectangular ring sealing strip 251 to fit and squeeze the card slot 24, so that the rectangular ring sealing strip 251 can seal the connection range between the card slot 24 and the sealing plate 25 to prevent water leakage.

[0024] A fixed tube 4 is installed on the outside of the blocking plate 25, and a limiting plug rod 41 is slidably connected to the inner wall of the fixed tube 4. Insert rings 42 aligned with the limiting plug rod 41 are installed on both sides of the bidirectional tube 2, and the limiting plug rod 41 is inserted into the inner wall of the corresponding plug ring 42; the blocking plate 25 supports the fixed tube 4, and the fixed tube 4 supports the limiting plug rod 41. When the blocking plate 25 and the slot 24 are closed, the limiting plug rod 41 is aligned with the plug ring 42, and the position of the blocking plate 25 is locked by controlling the limiting plug rod 41 to be inserted into the plug ring 42.

[0025] The side wall of the limiting plug 41 is fixedly connected to a fixing ring 411, and one side of the fixing ring 411 is fixedly connected to a return spring 412, and one end of the return spring 412 contacts the inner wall of the fixed tube 4; the fixed tube 4 limits the limiting plug 41 inside through the fixing ring 411, and the return spring 412 pushes the fixing ring 411, so that the fixing ring 411 can drive the limiting plug 41 to be stably inserted into the plug ring 42, thereby improving the stability of the sealing plate 25 when connected to the slot 24.

[0026] The working principle and usage process of the present invention are as follows: when the device is in use, by controlling the rotation of the two-way pipe 2, the other water trough 22 can be spatially docked with the two rotating connecting pipes 21 to realize water flow switching, and the two-way pipe 2 is locked and no longer rotated. The filter cup 3 and the inner filter pipe 31 filter and remove impurities from the water flow passing through the water trough 22 to prevent impurities from continuing to flow to the rear of the water source transmission route, thereby reducing the occurrence of blockage inside the PE pipe 1. The other filter cup 3 is in the non-working area, and the filter cup 3 can be cleaned at this time. By pulling the limit plug rod 41 out of the plug ring 42, the sealing plate 25 can drive the filter cup 3 to open, and the filter cup 3 can be removed for cleaning. There is no need to disconnect the water route to avoid affecting water use, and there is no need to disassemble the two pipes and connecting components. The operation is simple and convenient, saving time and effort, and improving efficiency.
