Description

Technical Field

[0001] The utility model relates to the technical field of pipeline connection, in particular to a gland loose sleeve compensating joint which is convenient to adjust. Background Technique

[0002] The gland loose sleeve compensating joint is a pipeline connection device designed to solve the problems of traditional pipeline connection methods and greatly improve the safety and stability of pipelines. It is applicable to the transportation of various media. The joint can easily adjust the installation length between both ends of the product and the pipeline or flange through a connection method with flanges on both sides. Currently, there are various gland loose sleeve compensating joints on the market, but there are still some disadvantages;

[0003] The existing gland loose sleeve compensating joint adjusts the length of the entire joint pipe by only setting one end of the joint pipe to be pulled and adjusted. Pulling only one end will cause instability during the installation and connection of the joint pipe. At the same time, the joint pipe connected to the pipeline will transport various media, and the media will contain different impurities. Failure to block the impurities will cause the joint to become blocked. In addition, the two sides of the joint are connected to the water pipe through flanges, and general connections will have problems such as weak sealing performance. For example, the Chinese utility model patent with the authorization announcement number CN210484932U discloses a gland loose sleeve compensating joint, including a first joint pipe. A first connecting flange is fixedly sleeved on the end of the surface of the first joint pipe. A second joint pipe is slidably connected to the pipe wall of the first joint pipe. A second connecting flange is fixedly sleeved on the end of the second joint pipe located outside the first joint pipe. A limiting groove is provided on the surface of the second joint pipe. By pulling up the hand-held strip plate, the sliding plate is pulled to slide in the connection box and the spring is compressed. When the inserting column strip slides out of the limiting inserting groove, the second joint pipe can slide in the first joint pipe. Through the sliding limit of the limiting piece and the limiting groove, the first joint pipe and the second joint pipe are not easily rotated and slid out of position. When the inserting column strip coincides with another limiting inserting groove, it can be popped out and clamped and fixed under the reset of the spring, thus achieving the effect of being convenient for flexible telescopic adjustment and fixation, and being more flexible and convenient to use. However, this device adjusts the length of the entire joint pipe by only setting one end of the joint pipe to be pulled and adjusted. Pulling only one end will cause instability during the installation and connection of the joint pipe. At the same time, the joint pipe connected to the pipeline will transport various media, and the media will contain different impurities. Failure to block the impurities will cause the joint to become blocked. In addition, the two sides of the joint are connected to the water pipe through flanges, and general connections will have problems such as weak sealing performance. Therefore, we propose a gland loose sleeve compensating joint which is convenient to adjust to solve the problems raised above. Content of the Utility Model

At the same time, the joint pipe connected to the pipeline will transport various media, and the media will contain different impurities. If the impurities are not blocked, it will cause the joint to become blocked. In addition, the two sides of the joint are connected to the water pipe by setting flanges, and general connections will have problems such as weak sealing performance.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0030] Please refer to Figures 1 - 6 , the present utility model provides a technical solution:

[0031] Embodiment 1: To solve the problems existing in the prior art, this embodiment adopts the following technical solution. A gland loose sleeve compensating joint that is easy to adjust is provided with a middle joint 1, and a fixing ring 2 is installed in the middle of the middle joint 1; an easy-to-adjust mechanism is arranged outside the middle joint 1, which can pull the movable joint 4 outward to adjust the length of the joint; an intercepting mechanism is arranged inside the flange 11 to intercept impurities in the flowing medium inside the joint, effectively avoiding the blockage of the joint; a sealing mechanism is arranged outside the connection between the flange 11 and the pipeline to strengthen the sealing performance between the flange 11 and the pipeline. First, pull the movable joint 4 to move outward outside the middle joint 1. Since a clamping groove 5 is opened inside the movable joint 4 and a clamping block 3 is installed outside the middle joint 1, the clamping groove 5 will slide outside the clamping block 3. At the same time, a connecting block 9 is fixedly arranged outside the movable joint 4, and the connecting block 9 can prevent the movable joint 4 from falling off during sliding. In addition, threaded holes 6 are symmetrically arranged at equal intervals on the left and right sides inside the movable joint 4 to control and limit the length of the movable joint 4 pulled and adjusted. Secondly, a fixing ring 2 is installed in the middle of the middle joint 1, and fixing brackets 7 are symmetrically installed on the left and right sides of the fixing ring 2. Threaded holes 6 are also opened inside the fixing brackets 7. After the movable joint 4 moves to a suitable position, the fixing brackets 7 and the movable joint 4 are fixed by a threaded rod 8. A hose 10 is arranged outside the movable joint 4, and the hose 10 can also lengthen the length of the joint. At the same time, a flange 11 is installed outside the hose 10, and a detachable filter screen 13 is arranged inside the flange 11. The filter screen 13 can prevent impurities in the flowing medium from entering the joint and causing blockage of the joint. In addition, connection holes 12 are opened at equal angles inside the flange 11, and pipelines can be connected through the connection holes 12. Secondly, a sealing gasket 18 is arranged outside the flange 11, and the sealing gasket 18 can rotate outside the flange 11. After the flange 11 is connected to the pipeline, fixing blocks 19 are symmetrically installed front and back below the sealing gasket 18, and the sealing gasket 18 is fixedly installed outside the connection between the flange 11 and the pipeline by inserting bolts 20 into the fixing blocks 19, strengthening the sealing performance of the flange 11 connecting the pipeline.

[0032] For the existing gland loose sleeve compensating joint, by only setting the adjustment of pulling one end of the joint pipe, the length of the entire joint pipe is adjusted. Pulling only one end will cause instability when the joint pipe is installed and connected to the pipeline, such as Figure 1 、 Figure 2 and Figure 3As shown in the figure, the adjustment mechanism includes a fixing ring 2 arranged in the middle of the middle joint 1. At the same time, clamping blocks 3 are symmetrically and fixedly installed on the left and right sides of the middle joint 1, and a clamping groove 5 is slidably connected to the outside of the clamping block 3.

A rotating block 15 is arranged on the outside of the limiting block 14, and a convex block 16 is installed inside the rotating block 15. That is, the filter screen 13 is placed inside the rotating block 15 and the limiting block 14, and convex grooves 17 are equidistantly opened inside the filter screen 13. After the filter screen 13 is placed between the limiting block 14 and the rotating block 15, the rotating block 15 is rotated so that the convex block 16 installed inside the rotating block 15 is engaged with the convex groove 17, and the filter screen 13 can be fixed. The filter screen 13 can intercept sundries in the flowing medium from entering the inside of the joint, and at the same time, the filter screen 13 is also convenient for disassembly and can be regularly cleaned and replaced.

[0034] Embodiment 3: For the existing gland loose sleeve compensating joint, the two sides of the joint are connected to the water pipe by setting flanges 11. General connections will have problems such as weak sealing performance, such as Figure 1 , Figure 3 and Figure 6As shown in the figure, the sealing mechanism includes a gasket 18 rotatably arranged outside the flange 11. Connecting holes 12 are equally angularly opened inside the flange 11. The connecting holes 12 facilitate the connection between the flange 11 and the pipeline. After the flange 11 is connected to the pipeline, the gasket 18 is arranged outside the connection between the flange 11 and the pipeline. At the same time, fixing blocks 19 are arranged on the front and rear sides below the gasket 18. Then, bolts 20 are inserted into the fixing blocks 19 and tightened, so that the gasket 18 can be fixed outside the connection between the flange 11 and the pipeline, ensuring the sealing performance of the connection between the flange 11 and the pipeline.
