Description
Technical Field
[0001] The utility model relates to the technical field of polytetrafluoroethylene lined pipes, in particular to a polytetrafluoroethylene lined pipe that is easy to install. Background Art
[0002] PTFE lined pipe is a polytetrafluoroethylene composite pipe with its inner wall covered with polytetrafluoroethylene. It has excellent corrosion resistance, high temperature resistance and non-stick properties. It is very suitable for transporting highly corrosive and high temperature media. It is used in chemical, food, pharmaceutical, medical and other fields. PTFE lined pipes need to be docked and installed when in use, which can facilitate the transmission of the media.
[0003] When the existing technology is in use, the positioning rods provided on both sides of the sealing plate are embedded in the positioning holes, so that the first PTFE-lined anti-corrosion pipe and the second PTFE-lined anti-corrosion pipe can be connected and sealed, and the connecting sleeve is used to rotate the external threads of the first PTFE-lined anti-corrosion pipe and the second PTFE-lined anti-corrosion pipe, so that the first PTFE-lined anti-corrosion pipe and the second PTFE-lined anti-corrosion pipe can be quickly connected and installed. However, in actual use, when the pipe is subjected to vibration, pressure changes or impact, the fit between the positioning rod and the positioning hole may loosen, resulting in the risk of leakage or falling off at the connection. Therefore, it is necessary to redesign an easy-to-install PTFE-lined pipe to address the above problem. Utility Model Content
[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to provide a polytetrafluoroethylene lined pipe which is easy to install.
[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:
[0006] The cam is fixedly mounted on a bottom surface of the fixing plate, and the fixing plate is fixedly mounted on a bottom surface of the fixing plate.
[0007] Preferably, the sliding mechanism comprises a sliding rod fixedly connected to the inner wall of the device groove, the outer wall of the sliding rod is slidably connected to a slide plate, and the clamping block is fixedly connected to the outer wall of the slide plate.
[0008] Preferably, a spring is sleeved on the outer wall of the slide rod, one end of the spring is fixedly connected to the inner wall of the device groove, and the other end of the spring is fixedly connected to the side wall of the slide plate.
[0009] Preferably, a sealing gasket is fixedly connected in the slot, and outer walls on both sides of the sealing gasket are in contact with two groups of pipeline ports respectively.
[0010] Preferably, the end of the spring is fixedly connected to a limit plate, and the outer wall of the end of the slide is fixedly connected to a handle.
[0011] Preferably, the inner wall of the limiting groove and the inner wall of the clamping block are both arc-shaped, and the curvature is consistent.
[0012] The utility model has the following beneficial effects:
[0013] 1. The utility model realizes the quick fixed installation of two sets of pipes by arranging upper clamping plates, lower clamping plates and screws and the like, and the clamping design of the upper clamping plates and the lower clamping plates. The sealing gasket fixedly connected in the clamping groove provides an effective seal at the pipe port. The screw cooperates with the clamping block and the limiting groove through the fixing hole to ensure accurate positioning and tightening during the tightening process. With the help of the elasticity of the spring, the clamping block is always tightly fitted to the inner wall of the limiting groove to avoid loosening of the screw due to vibration, thereby improving the tightness and stability of the connection. At the same time, the design of the device simplifies the installation process. The user only needs to take a few simple steps to realize the quick installation of the two sets of pipes, which greatly improves the installation efficiency and reduces the problem of leakage at the connection due to vibration of the pipe.
[0014] 2. The utility model provides a reliable sealing guarantee by providing a sealing gasket in the card slot, and its two sides are in close contact with the pipe port. The tight connection between the card block and the limit groove after installation prevents the screws from loosening and improves the sealing of the overall connection. With the help of this structural design, the defect of easy leakage at the connection under various working conditions is overcome. Even in a relatively harsh operating environment, it can still ensure the efficient sealing of the pipeline system, avoid medium leakage, and ensure the safety of equipment and environment.
