Claims

[Scope of utility model registration request]

Straddle both ends of the connected pipes with their ends facing each other,
A socket pipe is fitted onto the outside of the socket pipe, with both ends facing toward the center of the pipe, and tightening rings fitted onto the outside of the pipe to be connected outside both ends of the socket pipe are arranged so that they are close to each other and facing towards the center of the pipe. An elastic packing ring is tightened in a direction parallel to the line and fitted into the gap between the inner peripheral surface of both ends of the socket pipe and the outer peripheral surface of the connected pipe at the corresponding position. In a pipe fitting that is press-fitted into the gap on opposite sides of the ring, the elastic packing ring has upper and lower parts extending in a V-shape from one side of a base ring having a thickness equal to the radial length of the gap. The lip piece extends from the other side of the base ring part along the center line of the tube, has an outer peripheral surface as a sloped surface that matches the sloped surface of the end edge of the socket tube, and has an inner peripheral surface as a sloped surface that matches the sloped surface of the end edge of the socket tube. Due to the tightening force of the tightening ring, the upper and lower lip pieces extending in a V-shape, which have a gap between them, are formed by the tightening force of the tightening ring. The socket tube is elastically deformed into a substantially parallel shape and brought into close contact with the inner circumferential surface of the socket tube and the outer circumferential surface of the connected tube. The slope of the pipe is in close contact with the outer circumferential surface of the pipe to be connected.
A dresser type pipe joint in which the space between the deformed upper and lower lip pieces is communicated with the inside of the pipe to be connected.
