（発明が解決しようとする課題）
このような従来の管継手にて接続された管内に高温の流
体を通流させた場合、前記弾性シール部材の材質は通常
、熱に弱くて軟化し易いものであるため、該弾性シール
部材を上述のように弾性変形させる状態に予め押圧して
おいたとしても、該弾性シール部材が軟化変形してそれ
に対する押圧力が弱まり、該押圧力によるシール効果が
低下してしまうという問題があった。(Problems to be Solved by the Invention) When high-temperature fluid is passed through pipes connected by such conventional pipe joints, the material of the elastic sealing member is usually one that is susceptible to heat and easily softens. Therefore, even if the elastic seal member is pressed in advance to a state where it is elastically deformed as described above, the elastic seal member softens and deforms and the pressing force against it becomes weaker, and the sealing effect due to the pressing force is reduced. There was a problem that the performance decreased.

がある。Therefore, in order to solve this problem, a first measure is to make the pressing force sufficiently large, a second measure is to perform sealing at a plurality of locations with the elastic seal member, and the like. However, there is a limit to implementing the first measure, and implementing the second measure requires forming a plurality of seal grooves in the joint seal, which reduces the strength of the joint and There is a problem in that the cost of the joint increases.

もない。Such a pipe joint of the present invention has the four convex portions a1,
Since the structure is such that a2, a3, and a4 can be pressed individually and exhibit a sealing effect individually, a sealing effect similar to that obtained when sealing is performed over multiple locations can be obtained. Moreover, since the seal groove into which the elastic seal member 13 is inserted is formed at only one place in the joint seal part 11a, compared to the case where seal grooves are provided at multiple places, the seal groove in the joint seal part 11a is There is enough strength
Furthermore, there is no factor that increases the manufacturing cost of the joint.

ようになる。Furthermore, among the four convex portions a8, a2, a3, a4,
The convex portion a closest to the fluid flowing through the pipe is pressed and inclined as described above, but when the pressure from the fluid is applied to this convex portion a, the convex portion a is brought into closer contact with the pipe connecting portion 12. It is tilted and pressed in such a manner that it has a greater sealing effect (so-called self-sealing effect) due to the tilted pressing.
