Abstract
Description
Technical Field
[0001] This utility model relates to the field of clamp gasket disassembly and assembly technology, specifically, to a clamp gasket quick disassembly and assembly device. Background Technology
[0002] Currently, in the field of biotechnology, clamp connection is the most common way to connect pipelines. A gasket is placed in the chuck first, and then the clamp is used to fix the connection. The gasket is used to seal the chuck interface, and the gasket is mainly made of PTFE, polytetrafluoroethylene, and other materials.
[0003] The gasket should be inspected and replaced according to its material, number of uses, and the temperature and pressure during use. After the clamp is removed, a certain gap must be left at the chuck interface to remove the gasket, then replace it with a new one, and reinstall the clamp. In practice, separating the two chuck interfaces to remove the old gasket is difficult and may affect adjacent components. Furthermore, when installing a new gasket, if there is no sufficient gap between the two chuck interfaces, forcing the installation may damage the new gasket. There is also a risk that the two chuck interfaces may not be on the same level, leading to leakage after the new gasket is installed. Currently, there are no special tools available; instead, pry bars or wrenches are used to pry open the interface to replace the gasket. This operation is time-consuming, laborious, and risky.

[0046] According to the quick-release device for clamp gaskets provided by this utility model, the device acts on the chuck 301 interface of the pipeline 3. The two pipelines 3 are connected by a chuck interface, and the clamp is used to fasten the chuck 301. The purpose of this quick-release device is to separate the two sections of pipeline 3 axially. Figure 1 As shown, it includes a clamp 1, a U-shaped groove 2, and a telescopic bracket 4; the clamp 1 is fixedly clamped on the pipeline 3 and located on both sides of the chuck 301 interface; the U-shaped groove 2 is fixed between the clamps 1 on both sides, and the pipeline 3 is located in the U-shaped groove 2; the clamps 1 on both sides are connected to the U-shaped groove 2 through an axial adjustment mechanism at the end of the U-shaped groove 2. The axial adjustment mechanism is used to adjust the axial distance between the clamp 1 and the U-shaped groove 2, thereby realizing the docking and separation of the chuck 301 at the ends of the two pipelines 3, so as to facilitate the installation and removal of gaskets.
[0047] The telescopic bracket 4 is installed inside the U-shaped groove 2 to support the pipeline 3, thereby ensuring the coaxiality between the two pipeline sections 3. In a preferred embodiment, the telescopic bracket 4 includes a bolt 401 and a support frame 402 located at the end of the bolt 402. The support frame 402 is used to support the pipeline 3.
