Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of groove type connectors, in particular to a groove type connector for pipelines. Background Art
[0002] Grooved connectors are a new type of steel pipe connection fittings, also known as clamp connections. This connection method has many advantages, such as simple operation, reliable connection, low fluid resistance, and convenient maintenance. Grooved connectors are composed of two major categories of products: pipe fittings that act as connection seals and pipe fittings that act as connection transitions.
[0003] Common grooved connectors are generally composed of a sealing rubber ring, a clamp and a locking bolt. When connecting, the inner rubber sealing ring is placed on the outside of the connected pipe, and then the locking bolt is rotated to squeeze the clamp, so that the clamp is clamped on the surface of the pipe, and the pipes are limited. Then the pipes can be connected. The sealing rubber ring is generally in contact with the surface of the pipe through the extrusion force of the clamp. However, when the clamp is installed, the two sides of the clamp will squeeze the surface of the pipe, and only the middle part of the clamp will squeeze the sealing rubber ring. The area of pressure applied by the clamp is large, and only a part of the force can fix the sealing rubber ring to the connection of the pipe. In addition, the connection of the pipe will impact the sealing rubber ring when the fluid is flowing, making it difficult for the sealing rubber ring to stably seal the connection of the pipe. Utility Model Content
