Technical Field

[0001] The utility model relates to the technical field of sealing joints, in particular to a bend sealing joint for aluminum alloy pipelines. Background Art

[0002] A pipe fitting is a component used to connect pipes. It allows for detachable connections between pipes. Pipe fittings are used in many fields such as hydraulic systems, industrial pipelines, water supply and drainage systems, etc. Welding is often used for aluminum alloy pipe joints.

[0003] Currently, aluminum alloy pipes are butt-jointed by welding, which can easily damage the aluminum alloy surface. Welding is also dangerous and requires a certain level of skill from the construction workers. After long-term use, the joints of aluminum alloy pipes are prone to rust. In addition, the side walls of the pipes need to be cut into bevels before welding the pipe joints to make the contact between the two pipes closer. This method is cumbersome and inefficient. Welding alone is not conducive to ensuring the tightness of the connection inside the pipes, and is not convenient for subsequent maintenance.

[0004] Therefore, the utility model provides a pipe elbow sealing joint for aluminum alloy pipelines to solve the above problems. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a pipe elbow sealing joint for aluminum alloy pipelines, which solves the problems raised in the above-mentioned background technology.

A screw is threadedly connected to the top end of the sealing box, and the lower bottom end of the screw is fixedly connected to the slide.

[0008] A further improvement of the technical solution of the present utility model is that a rubber spacer for increasing friction is fixedly connected to the inner wall of the washer, and a handle for rotating and tightening is fixedly connected to the end of the screw.

[0009] A further improvement of the technical solution of the present invention is that: an elbow for butting the aluminum tube is fixedly connected to the inner wall of the tube body, and screw grooves for butting are provided on the inner walls at both ends of the elbow.

[0010] A further improvement of the technical solution of the present utility model is that a heat shrink film is provided on the inner wall of the tube body at one side of the elbow, and one end of the heat shrink film is connected to the side wall of the elbow.

[0024] Reference Figures 1-6 , this utility model provides two technical solutions:

[0025] Example 1:

[0026] A pipe elbow sealing joint for aluminum alloy pipelines, comprising a pipe body 1, which is formed by butting a pipe A 101 and a pipe B 102 together. A sealing strip 103 is fixedly connected to the side wall of the pipe A 101, and a sealing groove 104 is provided on the side wall of the pipe B 102. A sealing assembly 2 is provided inside the pipe body 1.

[0027] The sealing assembly 2 includes a gasket 201 connected to the inner wall of the A tube 101 by a spring, and a pad 202 for tightening the seal is fixedly connected to the inner wall of the B tube 102. A plurality of wire grooves 203 are opened inside the pad 202, and a stranded wire 204 for tensioning is arranged inside the wire groove 203. One end of the stranded wire 204 is fixedly connected to the end of the gasket 201. The outer wall of the B tube 102 is located on the outer wall of the pad 202 and is fixedly connected to a sealing box 205. A slide 206 is slidably connected to the inner wall of the sealing box 205, and the lower bottom end of the slide 206 is fixedly connected to the end of the stranded wire 204. A plurality of tension springs 207 are fixedly connected to the outer wall of the slide 206, and a fixed plate 208 is fixedly connected to the inner wall of the sealing box 205, and the lower bottom end of the fixed plate 208 is fixedly connected to the tension spring 207. A screw 209 is threadedly connected to the top of the sealing box 205, and the lower bottom end of the screw 209 is fixedly connected to the slide 206.

[0028] A rubber spacer 210 for increasing friction is fixedly connected to the inner wall of the washer 201 , and a handle 211 for rotating and tightening is fixedly connected to the end of the screw rod 209 .

[0029] Specifically, the detachable A tube 101 and B tube 102 can clearly show the internal situation of the tube body 1, and the detachable manner facilitates the later maintenance and care of the pipeline. The setting of the sealing strip 103 and the sealing groove 104 can enhance the tightness of the connection between the two. When the pipeline to be docked is inserted into the pipeline, the rotating handle 211 drives the screw 209 to rotate, drives the slide plate 206 to slide in the sealing box 205, drives the stranded wire 204 connected to its lower end to be stretched outward, and then drives the washer 201 at the other end of the stranded wire 204 to tighten the aluminum alloy pipeline, thereby improving the airtightness between the device and the aluminum alloy pipeline, and uses the rubber spacer 210 to increase the friction with the aluminum alloy pipeline to prevent the aluminum alloy pipeline from loosening.

[0030] Example 2:

[0031] Based on Example 1:

[0032] An elbow 105 for butting against the aluminum tube is fixedly connected to the inner wall of the tube body 1 , and screw grooves 106 for butting against the aluminum tube are provided on the inner walls at both ends of the elbow 105 .

[0033] A heat shrink film 107 is provided on the inner wall of the tube body 1 on one side of the elbow 105 , and one end of the heat shrink film 107 is connected to the side wall of the elbow 105 .

[0034] The outer wall of the tube body 1 is provided with a tightening ring 108 for connecting the A tube 101 and the B tube 102. The tightening ring 108 rotates along the side wall rotation axis 109. The outer wall of the tightening ring 108 is fixedly connected with a plurality of tightening seats 110.

[0035] A bolt 111 is threadedly connected to the side wall of one of the tightening seats 110 , and a screw hole 112 connected to the bolt 111 is opened on the outer wall of the other tightening seat 110 .

[0036] Specifically, when the aluminum alloy pipe is inserted into the pipe body 1, the aluminum alloy pipe with threads is rotated to be threadedly connected to the elbow 105. The pipe can be quickly connected by quickly connecting the aluminum pipe thread and the screw groove 106 on the inner wall of the elbow 105, and the connectivity of the pipe can be enhanced by the threaded connection. After the connection, the heat shrink film 107 is roasted by an external flame. The characteristics of the heat shrink film 107 can greatly improve the connection tightness between the aluminum pipe and the elbow 105. After the connection, the tightening ring 108 is inserted into the outer wall of the pipe body 1. Since the two can be rotated by the rotating shaft 109, the outer wall of the pipe can be quickly closed. The setting is extremely flexible and multiple settings can be set according to the on-site conditions. Then, by rotating the bolt 111, one tightening seat 110 is threadedly connected to the screw hole 112 of another tightening seat 110, thereby further improving the connection tightness of the two tightening seats 110.

[0037] Working principle: First, insert the threaded aluminum alloy pipe into the elbow 105 inside the pipe body 1, and rotate the two through the screw groove 106 to improve the connection tightness, and then burn the heat shrink film 107 through the flame to further improve the connection tightness of the aluminum alloy pipe and the elbow 105, and then connect the A pipe 101 and the B pipe 102, and then rotate the handle 211 to drive the screw 209 to rotate, drive the connected slide 206 to slide, and then drive the stranded wire 204 to slide inside the wire groove 203, further drive the gasket 201 to shrink toward the pad 202, and use the rubber spacer 210 on the inner wall to further squeeze the aluminum alloy pipe, which will not damage the outer wall of the aluminum alloy pipe and can greatly improve the connection tightness between the two. When maintenance is needed, reverse the handle 211 to drive the screw 209 to reset, and the screw 209 can be reset by the setting of the tension spring 207. This device can greatly improve the connection speed of the pipe and improve the connection tightness inside the pipe.
