Abstract

The utility model provides a straight pipe joint. The straight pipe joint comprises a joint body, wherein outer threads are arranged at two ends of the joint body. A connection part is arranged in the middle of the outer wall of the joint body. Cutter withdrawal grooves are arranged between the connection part and the outer threads. Circular protrusions are arranged on the end portions of the connection part. Circular grooves used for containing sealed rings are arranged between the inner walls of the circular protrusions and the outer walls of the cutter withdrawal grooves. According to the straight pipe joint, the sealed rings are arranged in the circular grooves, the installation is convenient, sliding is not prone to occurrence and sealing effect is improved. Due to the fact that the connection part in the middle of the joint is quadrilateral or regular hexagon, the installation is convenient.

Description

Free flow coupling
Technical field
The utility model relates to a kind of pipe joint, particularly a kind of free flow coupling.
Background technique
Be connected by pipe joint between pipeline and the pipeline, in order to guarantee sealing, can be at joint installing seal ring, but traditional seal ring is located at joint head, and it is very inconvenient to install, and causes easily leakage; And a lot of pipe joint integral body are cylindrical, and only the joint at the middle part offers anti-slip tank, easily cause when therefore installing and skid.
