Description

Technical Field

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

[0002] Currently, existing pipe filter screens typically consist of an integrated mounting ring and a filter plate fixed inside the mounting ring. The filter plate has multiple filter holes evenly distributed on one surface for drainage. With this structure, the filter plate is easily deformed by the impact of the medium. At the same time, the connection between the mounting ring and the pipe is prone to breakage, causing blockage of the pipe later. Moreover, maintenance is difficult and the blockage is hard to clear. Utility Model Content

[0003] The purpose of this utility model is to provide a pipeline filter that can prevent the filter screen from breaking and falling off during use, avoid pipeline blockage caused by breakage, and facilitate pipeline maintenance and filter screen replacement in the later stage.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a pipeline filter, comprising a first pipeline and a second pipeline symmetrically arranged, a clamp installed between the first pipeline and the second pipeline, and a sealing assembly sandwiched between the first pipeline and the second pipeline. The sealing assembly includes a sealing sleeve, a fixing ring, and an annular filter screen. The sealing sleeve is clamped between the first pipeline and the second pipeline, and the annular filter screen is clamped and fitted onto the sealing sleeve to form a filter. One end of the fixing ring is connected to the sealing sleeve and fitted onto the first pipeline to form an installation position.

[0005] Preferably, a connecting strip is provided on the outer circumferential surface of the sealing sleeve, one end of which is fixedly connected to the sealing sleeve and the other end is fixedly connected to the fixing ring.

[0006] Preferably, the first pipe has a first mounting groove, and the second pipe has a corresponding second mounting groove, and the sealing sleeve is clamped in the first mounting groove and the second mounting groove.

[0007] Preferably, the sealing sleeve is located on one side of the second mounting groove and extends inward to provide a positioning boss, the positioning boss has an annular groove, and the annular filter screen is embedded in the annular groove.

[0008] Preferably, the sealing sleeve has a clearance groove on one side of the positioning boss.

[0009] Preferably, the retaining ring has an annular through hole adapted to the first pipe.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: First, the fixing ring is fitted onto the first pipe; second, the annular filter screen is clamped into the annular groove of the sealing sleeve to form a fixation; finally, the sealing sleeve is clamped into the first mounting groove and the second mounting groove, and the first pipe and the second pipe are clamped together by clamping the clamp to form a clamping fixation of the sealing sleeve. In addition, the sealing sleeve is provided with a positioning protrusion, which can avoid clamping pressure on the filter screen when the pipe is clamped to avoid deformation. It can prevent the filter screen from breaking and falling off during use, and avoid pipe blockage after breakage. It also facilitates the later maintenance of the pipe and replacement of the filter screen. Attached Figure Description

[0014] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Example: As attached Figure 1 and attached Figure 2A pipeline filter, as shown, includes a first pipeline 1 and a second pipeline 2 symmetrically arranged. A clamp (for securing the first pipeline 1 and the second pipeline 2) is installed between the first pipeline 1 and the second pipeline 2. A sealing assembly 4 is sandwiched between the first pipeline 1 and the second pipeline 2. The sealing assembly 4 includes a sealing sleeve 5 (made of rubber), a fixing ring 8 (made of rubber), and an annular filter screen 9. The sealing sleeve 5 is clamped between the first pipeline 1 and the second pipeline 2. The annular filter screen 9 is clamped and fitted onto the sealing sleeve 5 to form a filter. One end of the fixing ring 8 is connected to the sealing sleeve 5 and fitted onto the first pipeline 1. The installation positioning is formed on the first pipe 1. First, the fixing ring 8 is put on the first pipe 1. Then, the annular filter screen 9 is clamped in the annular groove 14 of the sealing sleeve 5 to form a fixation. Finally, the sealing sleeve 5 is clamped in the first mounting groove 11 and the second mounting groove 12. The first pipe 1 and the second pipe 2 are clamped together with clamps to form a clamping fixation of the sealing sleeve 5. The sealing sleeve 5 is provided with a positioning protrusion 13, which can avoid clamping pressure on the filter screen when the pipe is clamped to avoid deformation. It can prevent the filter screen from breaking and falling off during use, and avoid pipe blockage after breakage. It is convenient for later maintenance of the pipe and replacement of the filter screen.

[0016] As attached Figure 1 As shown, a connecting strip 10 (made of rubber and integrally connected to the sealing sleeve 5 and the fixing ring 8) is provided on the outer circumferential surface of the sealing sleeve 5. One end of the connecting strip 10 is fixedly connected to the sealing sleeve 5 and the other end is fixedly connected to the fixing ring 8, so as to realize the connection relationship between the sealing sleeve 5 and the fixing ring 8, and to prevent the sealing sleeve 5 from falling off and blocking the pipeline.

[0017] As attached Figure 1 As shown, the first pipe 1 has a first mounting groove 11, and the second pipe 2 has a corresponding second mounting groove 12. The sealing sleeve 5 is clamped in the first mounting groove 11 and the second mounting groove 12. Unlike the clamping setting of the prior art, the first mounting groove 11 and the second mounting groove 12 are used to achieve limiting and clamping, which can avoid deformation of the sealing sleeve 5.

[0018] As attached Figure 1 As shown, the sealing sleeve 5 is located on one side of the second mounting groove 12 and extends inward to provide a positioning boss 13 (which is an integral structure connection). The positioning boss 13 has an annular groove 14, and the annular filter screen 9 is embedded in the annular groove 14 to avoid the annular filter screen 9 being squeezed by the first pipe 1 and the second pipe 2, effectively preventing the deformation and damage of the annular filter screen 9.

[0019] As attached Figure 1As shown, the sealing sleeve 5 has a relief groove 15 (in an annular shape) on one side of the positioning boss 13, which provides pressure for the impact of the medium and has a good buffering effect.

[0020] As attached Figure 1 As shown, the fixing ring 8 has an annular through hole 16 adapted to the first pipe 1 for clamping onto the first pipe 1, and the inner diameter opening of the annular through hole 16 is smaller than the inner circumferential diameter of the first pipe 1.
