Description

Technical Field

[0001] This utility model relates to the field of pipe fittings technology, specifically to a pipe fitting with a filtering function. Background Technology

[0002] Pipe fittings are core components in pipeline systems used for connecting, turning, branching, or changing pipe diameters. Their core function is to achieve a sealed and secure connection between pipes through mechanical structures. They are widely used in water supply and drainage, petrochemicals, hydraulic transmission, food processing, and other fields. During the operation of a pipeline system, the medium (such as water, oil, gas, slurry, etc.) often carries impurities. These impurities mainly come from debris left over from pipe installation, particles contained in the medium itself (such as sand, gravel, rust), and flaking products caused by corrosion of the inner wall of the pipe. If they are not filtered in time, they will have a serious impact on the entire pipeline system and downstream equipment.

[0003] Existing pipe fittings do not have a filtration function, causing impurities in the medium to flow directly into downstream equipment, which not only shortens the service life of the equipment, but may also cause equipment failure, resulting in production interruption or safety hazards.

[0004] For example, a pipe fitting disclosed in CN207122692U includes a pipe body, an inlet end, and an outlet end. The inlet end and the outlet end are respectively located at both ends of the pipe body. A connecting reinforcement is provided between the inlet end and the pipe body. The inner diameter of the connecting reinforcement gradually decreases from the end connected to the inlet end to the end connected to the pipe body. A filter device is snapped onto the inner wall of the connecting reinforcement. Although this patent achieves the filtration function by setting a filter device at the inlet end and improving the cleanliness of the medium, its filter device is installed on the inner wall of the connecting reinforcement and does not have a convenient disassembly and assembly structure. This makes the operation cumbersome and the maintenance inconvenient when disassembling, cleaning or replacing the filter device.

[0005] Therefore, it is necessary to invent a pipe fitting with a filtering function to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a pipe fitting with a filtering function, which solves the problems of lacking filtering function and the cumbersome operation and poor maintenance convenience when disassembling the filtering device.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a pipe fitting with a filtering function, comprising a pipe fitting body, wherein filtering components are detachably arranged inside both ends of the pipe fitting body, the filtering components comprising a sleeve and a filter cylinder, the sleeve being coaxially sleeved outside the port of the pipe fitting body, the filter cylinder being coaxially fixedly arranged at the center of the sleeve and extending into the interior of the pipe fitting body, and filter screen one and filter screen two being sequentially arranged inside the filter cylinder along the medium flow direction, and four fixing components being arranged at the port of the sleeve and the pipe fitting body, the four fixing components being evenly distributed along the circumferential direction.

[0008] Preferably, a sealing gasket is provided between the inner wall of the sleeve and the outer wall of the fitting body.

[0009] Preferably, four limiting rods are evenly distributed around the inside of the sleeve along the circumferential direction, and a matching limiting slot is provided on the end face of the pipe fitting body at the corresponding position of the four limiting rods.

[0010] Preferably, four limiting sliders are evenly distributed around the outer wall of the filter cylinder in the circumferential direction. A limiting groove extending in the axial direction is provided on the inner wall of the pipe fitting body at the corresponding position of the four limiting sliders. The limiting sliders can slide along the limiting groove to achieve axial guidance of the filter cylinder.

[0011] Preferably, both filter screen one and filter screen two are sealed to the inner wall of the filter cylinder, and the pore size of filter screen one is larger than that of filter screen two.

[0012] Preferably, the fixing assembly includes a bearing, a fixing plate, and fixing bolts. The bearing is fixedly installed around the outer wall of the pipe fitting body. One end of the fixing plate is hinged to the bearing, and the other end can rotate around the hinge point to the outer wall of the sleeve.

[0013] Preferably, the fixing plate has a threaded hole, and the fixing bolt is threaded through the threaded hole. The end of the sleeve and the pipe fitting body has a coaxially connected fixing screw hole at the contact position with the fixing bolt. The fixing bolt can pass through the fixing screw holes of the sleeve and the pipe fitting body in sequence to achieve a fixed connection between the two.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows: 1. This utility model, through the design of the filter assembly, has filter screens one and two with different pore sizes arranged sequentially along the medium flow direction inside the filter cylinder of the filter assembly. This can intercept impurities of different sizes in stages, which not only avoids large particles of impurities clogging the fine filter screen, but also ensures the cleanliness of the output medium, meeting the medium transportation scenarios with high cleanliness requirements. 2. This utility model significantly reduces the maintenance difficulty and cost of the filter assembly through its modular and detachable structural design. The filter assembly and the pipe fitting connector body adopt a detachable connection method of "limit positioning + bolt fixing": During installation, the limit rod inside the sleeve is inserted into the limit slot of the connector body, and the limit slider of the filter cylinder slides along the limit groove on the inner wall of the connector, which can quickly achieve circumferential positioning and axial guidance of the filter assembly and ensure installation accuracy; during fixing, it is only necessary to rotate the fixing plate and screw in the fixing bolt to complete the fixing, which is convenient to operate. When it is necessary to clean or replace the filter screen, it is only necessary to remove the fixing bolt to take out the entire filter assembly, reducing maintenance time and workload.

[0017] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0018] This utility model provides, for example Figure 1-6The pipe fitting shown includes a pipe fitting body 1. Filter components 2 are detachably installed inside both ends of the pipe fitting body 1. The filter components 2 include a sleeve 201 and a filter cylinder 202. The sleeve 201 is coaxially sleeved outside the port of the pipe fitting body 1. The filter cylinder 202 is coaxially fixed at the center of the sleeve 201 and extends into the interior of the pipe fitting body 1. A sealing gasket is provided between the inner wall of the sleeve 201 and the outer wall of the pipe fitting body 1. A filter screen 203 and a filter screen 204 are sequentially arranged inside the filter cylinder 202 along the medium flow direction. Both filter screens 203 and 204 are sealed to the inner wall of the filter cylinder 202, and the aperture of filter screen 203 is larger than that of filter screen 204.

[0019] In this embodiment, the combination of filter screen 203 and filter screen 204 in filter assembly 2 can perform graded filtration of the medium. First, larger particulate impurities are filtered through filter screen 203 with larger pore size, and then smaller particulate impurities are filtered through filter screen 204 with smaller pore size, thereby improving the filtration effect.

[0020] Four limiting rods 3 are evenly distributed around the inside of the sleeve 201 along the circumferential direction. A limiting slot 4 is provided on the end face of the pipe fitting body 1 at the corresponding position of the four limiting rods 3. Four limiting sliders 5 are evenly distributed around the outer wall of the filter cylinder 202 along the circumferential direction. A limiting groove 6 extending axially is provided on the inner wall of the pipe fitting body 1 at the corresponding position of the four limiting sliders 5. The limiting sliders 5 can slide along the limiting groove 6 to achieve axial guidance of the filter cylinder 202.

[0021] In this embodiment, the cooperation of the limiting rod 3 and the limiting slot 4 can position the sleeve 201 in the circumferential direction to prevent the sleeve 201 from rotating relative to the pipe fitting body 1. The cooperation of the limiting slider 5 and the limiting groove 6 can guide the filter cylinder 202 in the axial direction, so that the filter cylinder 202 can be accurately installed into the pipe fitting body 1. At the same time, it ensures the stability of the filter cylinder 202 during installation and disassembly, avoids its shaking or displacement, and ensures the correct assembly of the filter assembly 2 and the pipe fitting body 1.

[0022] Four fixing components 7 are provided at the ports of the sleeve 201 and the pipe fitting body 1. The four fixing components 7 are evenly distributed along the circumference. Each fixing component 7 includes a bearing 701, a fixing plate 702, and a fixing bolt 703. The bearing 701 is fixedly installed around the outer wall of the pipe fitting body 1. One end of the fixing plate 702 is hinged to the bearing 701, and the other end can rotate around the hinge point to the outer wall of the sleeve 201. The fixing plate 702 has a threaded hole, and the fixing bolt 703 is threaded through the threaded hole. The ports of the sleeve 201 and the pipe fitting body 1 have coaxially connected fixing screw holes 704 at the contact positions with the fixing bolt 703. The fixing bolt 703 can pass through the fixing screw holes 704 of the sleeve 201 and the pipe fitting body 1 in sequence to achieve a fixed connection between the two.

[0023] In this embodiment, the four fixing components 7 are evenly distributed along the circumference to ensure that the sleeve 201 is firmly connected to the pipe fitting body 1 and that the force is evenly distributed. The structure of the bearing seat 701 and the hinged fixing plate 702 allows the fixing plate 702 to rotate flexibly, facilitating installation and disassembly. The cooperation of the fixing bolts 703 and the fixing screw holes 704 can tightly fix the sleeve 201 and the pipe fitting body 1 together, preventing the filter component 2 from loosening or falling off during use, and ensuring the stability and reliability of the entire pipe fitting structure.

[0024] Working principle of this utility model: Refer to the instruction manual appendix Figure 1-6 When using this utility model, firstly, connect both ends of the pipe fitting body 1 to the medium conveying pipeline so that the medium can flow smoothly into the pipe fitting body 1. After the medium flows into the pipe fitting body 1, it first enters the filter cylinder 202 of the filter assembly 2 and comes into contact with the first filter screen 203. Since the pore size of the first filter screen 203 is large, larger particles of impurities in the medium will be intercepted on the surface of the first filter screen 203, achieving preliminary filtration. The medium after preliminary filtration by the first filter screen 203 continues to flow and reaches the second filter screen 204, which can further intercept smaller particles of impurities in the medium, achieving fine filtration. After two stages of filtration by the first filter screen 203 and the second filter screen 204, the impurity content of the medium is greatly reduced, and it flows out from the other end of the pipe fitting body 1 and enters the subsequent conveying pipeline or the use process. When the filter assembly 2 needs to be disassembled, cleaned, or replaced after long-term use, first loosen the fixing bolts 703 in the four fixing components 7 in sequence, so that the fixing bolts 703 come out of the fixing screw holes 704, but do not remove them completely to prevent the fixing plate 702 from shaking. Rotate the fixing plate 702 around the hinge point with the shaft seat 701 to move the fixing plate 702 away from the outer wall of the sleeve 201, making room for disassembling the sleeve 201 and the filter cylinder 202. Hold the filter cylinder 202 and slowly pull it outward along the direction of the limiting slide groove 6, so that the limiting slider 5 slides in the limiting slide groove 6, and pull the filter cylinder 202 out of the pipe fitting body 1. After the filter cylinder 202 is removed, remove the sleeve 201 from the outside of the port of the pipe fitting body 1. At this time, the limiting rod 3 comes out of the limiting slot 4, completing the disassembly of the filter assembly 2. If it is necessary to clean or replace parts of the filter assembly 2, the corresponding operations can be performed after disassembly.
