Description

Technical Field

[0001] The utility model relates to the technical field of insulating joints, in particular to a flange-connected insulating joint. Background Art

[0002] Flange-connected insulating joints are a common way of connecting pipes, usually used to connect different components or equipment in a pipe system. It consists of two flanges, insulating gaskets and bolts. This connection method can provide reliable sealing and insulation effects. It is commonly used in pipe systems in industrial fields, such as chemical, petroleum, and natural gas industries. However, each flange-connected insulating joint requires the insulating gasket to be tightened to prevent loosening.

[0003] The traditional flange-connected insulating joint is formed by tightening the bolts and nuts between the flanges to squeeze the insulating gasket between the two flanges to form a seal;

[0004] The traditional flange-connected insulating joint has the following problems: the bolts and nuts are prone to loosening after long-term use, affecting the sealing performance and safety between the joint and the flange. At the same time, it is also cumbersome during the loading and unloading process. For this reason, we propose a flange-connected insulating joint. Utility Model Content

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a flange-connected insulating joint, comprising a flange 1, a mounting hole and a disassembly mechanism;

[0007] Flange 1: There are two flanges, the bottom ends of the two flanges 1 are respectively fixedly connected with connecting pipes, the bottom ends of the connecting pipes are fixedly connected with flange 2, and an insulating gasket is provided between the flange 2 at the bottom and the flange 1 at the top;

[0008] Mounting holes: They are all opened inside flange 1, flange 2 and the insulating gasket, and a clamping mechanism is provided between two vertically adjacent mounting holes;

[0009] Disassembly mechanism: It is arranged inside the clamping mechanism, which makes the connection between the flanges more firm and tight, effectively improves the sealing and stability of the flange-connected insulating joint, and can significantly shorten the disassembly time of the flange-connected insulating joint and improve work efficiency.

[0010] Furthermore, the clamping mechanism includes a guide block, a pillar, a bayonet, a guide slide groove, an avoidance groove 1, a ball, a sliding column, a sliding hole and an avoidance groove 2. The avoidance groove 1 is opened at the lower end of the inner wall of the mounting hole on the flange 1, the inner wall of the avoidance groove 1 is opened with evenly distributed sliding holes, the inner wall of the sliding hole is slidably connected with a sliding column, and the end of the sliding column close to the center of the mounting hole is fixedly connected with a rolling ball. The guide slide groove is opened on the inner wall of the mounting hole, the inner wall of the guide slide groove is slidably connected with a guide block, and the end of the guide block close to the center of the mounting hole is fixedly connected to the outer surface of a pillar, the lower end of the pillar is opened with an avoidance groove 2, the inner wall of the avoidance groove 2 is opened with evenly distributed bayonet, and the bayonet is installed in cooperation with adjacent rolling balls, so that the connection between the flanges is more firm and tight.

[0011] Furthermore, the clamping mechanism also includes a spring, which is fixedly connected between one end of the ball away from the center of the mounting hole and the inner wall of an adjacent avoidance groove, and the spring is sleeved on the outer surface of the sliding column to improve the flexibility of the connection.

[0012] Furthermore, the clamping mechanism also includes a thread groove and a nut. The thread grooves are all opened at the upper end of the pillar, and the inside of the thread grooves are all threadedly connected with nuts, which improves the stability and reliability of the connection.

[0013] Furthermore, the disassembly mechanism includes an installation groove, a guide groove and a slider. The installation grooves are all opened inside the pillar, the inner walls of the installation grooves are all opened with evenly distributed guide grooves, the inner walls of the guide grooves are all slidably connected with sliders, and the bottom ends of the sliders are all installed in cooperation with vertically adjacent balls to facilitate unlocking.

[0014] Furthermore, the sliding blocks correspond to the upper and lower positions of the vertically adjacent rolling balls one by one, thereby improving the smoothness of the working process.

[0015] Furthermore, the disassembly mechanism also includes support rods, which are all located inside the installation grooves. The outer surfaces of the support rods located in the same installation groove are fixedly connected to one end of the slider close to the center of the installation groove to drive the disassembly mechanism.

[0016] Compared with the prior art, the beneficial effects of the utility model are: the flange connection type insulating joint has the following advantages:

[0017] 1. Insert the pillar into the mounting hole through the guide block and move along the inner wall of the guide slide groove. When moving, the bottom end of the pillar contacts the ball, which will generate an extrusion force. This extrusion force will push the slide column to slide into the slide hole and compress the spring, while driving the ball to move with the slide column, providing space for the pillar to go deeper. When the pillar moves to a certain extent, the bayonet in the avoidance groove 2 corresponds to the ball, thereby canceling the extrusion force on the ball, causing the spring to rebound. The action of the spring drives the slide column and the ball to rebound, so that the ball is engaged with the adjacent bayonet in the avoidance groove 2. Finally, the nut is threadedly connected to the threaded groove on the pillar and rotated until it is locked with the upper surface thread of flange 2, thereby making the connection between the flanges more firm and tight, effectively improving the sealing and stability of the flange-connected insulating joint, and avoiding leakage due to loose connection after long-term use.

[0018] 2. When disassembly is required, insert the support rod into the installation groove, and move the slider along the guide groove so that the bottom end of the slider contacts the adjacent ball. This contact will generate a certain extrusion force and push the slide column to slide along the slide hole. As the slide column moves, the spring will be compressed, causing the ball to separate from the bayonet, thereby releasing the connection. Finally, the support column can be taken out, which can significantly shorten the disassembly time of the flange-connected insulating joint, reduce cumbersome operating steps, and improve work efficiency.
