Description

Technical Field

[0001] The utility model relates to the technical field of pipeline connection structures, in particular to a pipeline connection component for secondary water supply equipment. Background Art

[0002] Secondary water supply refers to a form of water supply in which when the water pressure and water volume requirements of an organization or individual exceed the capacity of the municipal public water supply or the water supply network of self-built facilities, the urban public water supply or self-built facility water supply is stored and pressurized and then supplied to users or for self-use through pipelines.

[0003] In the prior art, a sealing gasket is usually arranged between two pipes, and the two pipes are connected by multiple bolts through the flange holes on the pipes. When connected, the two pipes squeeze the sealing gasket therein to seal the two pipes. Since the pre-tightening force of each bolt is different, the sealing gasket will be subjected to different pressures, and the part of the sealing gasket subjected to greater pressure will become thinner, that is, the two pipe interfaces are longitudinally asymmetric, and the two pipes are V-shaped. Due to the high pressure during secondary water supply, the water flow impacts the non-concentric pipes, which may cause the connector to loosen over a long period of time, and there is also the problem of leakage of damaged liquid due to compression of the sealing gasket. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a secondary water supply equipment pipeline connection assembly, aiming to alleviate the above-mentioned problems at least to a certain extent.

[0005] The above technical objectives of the utility model are achieved through the following technical solutions:

[0006] A secondary water supply equipment pipeline connection assembly, comprising:

[0007] Two rings disposed between the two pipes;

[0008] A plurality of positioning blocks are arranged on one side of the ring body, and the positioning blocks on the two ring bodies are located on two sides of the two ring bodies that are away from each other; the side of the positioning block close to the pipeline flange has a slope;

[0009] A connecting pipe is arranged between the two ring bodies and is adapted to the pipeline. A rubber tube is arranged outside the connecting pipe, and the cross section of the rubber tube is an isosceles trapezoid.

[0010] A plurality of positioning pieces are arranged inside the ring body, the pipeline flange is located between the positioning block on the ring body and the positioning piece, and a spring is arranged between the positioning piece and the ring body;

[0011] The moving component is arranged between the two ring bodies and is used to move the plurality of positioning blocks, so that the plurality of positioning blocks move toward the pipeline synchronously.

[0012] Preferably, the moving component includes a screw rod rotatably connected to one side of the ring body, and the screw rod is threadedly connected to the positioning block.

[0013] Preferably, the moving component also includes a first gear rotatably connected to the ring body, a second gear rotatably connected to the ring body and meshing with the first gear, a third gear meshing with the second gear is connected to the screw rod, and a connecting rod is connected between the first gears on the two ring bodies.

[0014] Preferably, the inner wall of the ring body is connected to a plurality of connecting plates, one side of the connecting plate is connected to a limiting rod, one side of the positioning plate is connected to a positioning shaft adapted to the flange hole of the pipeline, the positioning shaft is slidably connected to the limiting rod, and the spring is connected between the positioning plate and the connecting plate.

[0015] Preferably, a support rod is connected between the two ring bodies.

[0016] Preferably, one side of the ring body is connected with a plurality of folding rods connected to the connecting tube, and the folding rods pass through rubber tubes and are connected to the connecting tube.

[0017] In summary, the utility model mainly has the following beneficial effects:

[0018] By setting the ring body, when applying, one of the ring bodies is placed on one of the pipes that need to be connected, the positioning piece and the spring can position the ring body, ensuring that the positioning piece contacts the pipe flange basin and the flange is between the positioning piece and the positioning block, and the position of the other pipe can be appropriately moved so that the connecting pipe can be plugged into the two pipes and the rubber tube contacts the two pipes. The two ring bodies can be respectively sleeved on the flanges on the two pipes. Specifically, a moving component can be used to move multiple positioning blocks, and the multiple positioning blocks move toward the pipe. The slope on one side of the positioning block can contact the flange. When the positioning block continues to move, the slope can be used to squeeze and move the flange, and the two pipes overcome the force of the spring and move closer to each other. The rubber tube with an isosceles trapezoidal cross-section can be sleeved on the interface of the pipe, and as the pipe continues to move, part of the rubber tube can gradually move. When the rubber tube is partially fractured due to external force impact, the external fixation of the tube can be cancelled, and the positioning block can be moved by the moving component to allow the two tubes to continue to move closer to each other until the fractured part of the rubber tube is inserted into the tube. The rubber tube with an isosceles trapezoidal cross-section can seal the tube again. Compared with the sealing gasket ring used in the prior art, there is no need to cut off the water supply to the tube and disassemble and replace the sealing ring, which is a tedious step. This solves the problem that the different pre-tightening forces of each bolt cause the longitudinal asymmetry of the two tube interfaces, and the water flow impacts the non-concentric tubes, which may cause the connector to loosen over a long period of time.

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] refer to Figure 1-Figure 4 , a secondary water supply equipment pipeline connection assembly, comprising:

[0028] Two ring bodies 100 disposed between the two pipes;

[0029] A plurality of positioning blocks 101 are arranged on one side of the ring body 100. The positioning blocks 101 on the two ring bodies 100 are located on two sides of the two ring bodies 100 that are away from each other. The side of the positioning block 101 close to the pipeline flange has a slope 102.

[0030] A connecting pipe 103 is provided between the two ring bodies 100 and is adapted to the pipeline. A rubber tube 104 is provided outside the connecting pipe 103. The cross section of the rubber tube 104 is an isosceles trapezoid.

[0031] A plurality of positioning pieces 105 are arranged inside the ring body 100, the pipeline flange is located between the positioning block 101 on the ring body 100 and the positioning piece 105, and a spring 106 is arranged between the positioning piece 105 and the ring body 100;

[0032] A moving component is disposed between the two ring bodies 100 and is used to move the multiple positioning blocks 101, and the multiple positioning blocks 101 move toward the pipeline synchronously;

[0033] By setting the ring body 100, when it is used, one of the ring bodies 100 is placed on one of the pipes that need to be connected, and the positioning piece 105 and the spring 106 can position the position of the ring body 100, ensuring that the positioning piece 105 contacts the pipe flange basin and the flange is between the positioning piece 105 and the positioning block 101. The position of the other pipe can be appropriately moved so that the connecting pipe 103 can be plugged into the two pipes and the rubber tube 104 contacts the two pipes. The two ring bodies 100 can be respectively sleeved on the flanges on the two pipes. Specifically, a plurality of positioning blocks 101 can be moved by a moving component, and the plurality of positioning blocks 101 move toward the pipe. The slope 102 on one side of the positioning block 101 can contact the flange. When the positioning block 101 continues to move, the slope 102 can be used to squeeze and move the flange. The two pipes overcome the force of the spring 106 and move closer to each other. The rubber tube 104 with an isosceles trapezoidal cross section can be sleeved on the interface of the pipe, and as The continued movement of the pipeline can allow part of the rubber tube 104 to be gradually inserted into the pipeline. The connecting tube 103 is adapted to the inner diameter of the pipeline, which can ensure that the two pipelines are concentric with the connecting tube 103, avoiding the problem that the two pipelines are not concentric and the water flow will impact one of the pipelines with a larger pressure. If the pipeline is partially fractured due to external force impact, the external fixation of the pipeline can be cancelled, and the positioning block 101 can be continued to be moved by the moving component to allow the two pipelines to continue to move closer to each other until the fractured part of the rubber tube 104 is inserted into the pipeline. The rubber tube 104 with an isosceles trapezoidal cross-section can seal the pipeline again. Compared with the sealing gasket ring used in the prior art, there is no need to cut off the water supply to the pipeline and disassemble and replace the sealing ring. The cumbersome steps solve the problem that the pre-tightening force of each bolt is different, the two pipeline interfaces are longitudinally asymmetric, and the water flow impacts the non-concentric pipelines, which may cause the connector to loosen over a long period of time.

[0037] By setting the connecting rod 204, when in use, the first gears 201 on the two ring bodies 100 can be rotated synchronously through the connecting rod 204. The rotation of the first gear 201 can rotate the screw rod 200 through the second gear 202 and the third gear 203, thereby achieving the purpose of allowing multiple positioning blocks 101 to move synchronously toward the center of the pipeline.

[0038] As a further feature of the present invention, the inner side wall of the ring body 100 is connected with a plurality of connecting pieces 205, one side of the connecting piece 205 is connected with a limiting rod 206, one side of the positioning piece 105 is connected with a positioning shaft 207 adapted to the flange hole of the pipeline, the positioning shaft 207 is slidably connected to the limiting rod 206, and the spring 106 is connected between the positioning piece 105 and the connecting piece 205;

[0039] By providing the positioning shaft 207 and cooperating with the flange hole, the position of the ring body 100 can be quickly positioned, and the problem of poor sealing caused by the rotation of the ring body 100 during normal use of the subsequent pipeline can be avoided.

[0040] As a further feature of the present invention, a support rod 107 is connected between the two ring bodies 100;

[0041] By providing the support rod 107, the stability of the connection between the two ring bodies 100 can be improved. At the same time, during application, the operator can use tools such as a crowbar or a screwdriver to insert the tool between the support rod 107 and the connecting rod 204, and use the lever to pry the first gear 201 away from the rotation. During installation, there is no restriction from the tool, which achieves the effect of convenient and quick installation.
