Abstract
The utility model discloses a tube quick joint which comprises a joint body; both ends of the joint body are respectively provided with external threads, the outer walls on both ends of the joint body are respectively in threaded connection with end plugs, and the inner holes on both ends of the joint body are respectively in conical surface fit with conical seal rings. The tube quick joint can be connected with a feed pipe without the welding process, and the interior of the joint body reserves the flexible space for the feed pipe.
Description
Technical field
The utility model belongs to the joint link of tubing, specifically is a kind of rapid pipe joint of tubing.
Background technique
Rapid pipe joint is a kind of joint that does not need instrument just can realize pipeline connection or disconnection.Rapid pipe joint can be divided into: air rapid pipe joint, the rapid pipe joint of oxygen fuel gas, the shared rapid pipe joint of gas liquid, oil pressure rapid pipe joint, inert gas rapid pipe joint, the rapid pipe joint of coolant water temperature oil, semiconductor rapid pipe joint.But existing rapid pipe joint exists complex structure, and inconvenience is installed, and linking intensity is not enough.
The model utility content
The purpose of this utility model provides a kind of rapid pipe joint of tubing, avoids using welding just can connect supply pipe, and when temperature variation, and the inside of joint body is left and can be allowed the supply pipe extendable room.
The technical solution of the utility model is as follows:
A kind of rapid pipe joint of tubing includes joint body, and the two ends of described joint body have outside thread respectively, the plug that has been threaded respectively on the two ends outer wall of joint body, and cone match has the seal ring of taper in the two ends endoporus of joint body.
The inwall of described plug is provided with step, and the rear end of seal ring leans on step.
The two ends of joint body of the present utility model are respectively by the plug that is threaded, and avoid using welding just can connect supply pipe, and when temperature variation, and the inside of joint body is left and can be allowed the supply pipe extendable room.
