CONNECTOR MEMBER FOR CONNECTING PIPE LINE BLOCKS AND METHOD FOR MANUFACTURING THE SAME |
| 摘要 |
A connector member for connecting pipe line blocks according to an embodiment of this disclosure includes a hollow pipe-shaped portion made of a synthetic resin, and an O-ring. The pipe-shaped portion has a ring-shaped seal groove on an outer peripheral surface of the pipe-shaped portion, and an inclined surface having a conical surface shape on a side close to a pipe end from the seal groove on the outer peripheral surface, a diameter of the inclined surface being reduced toward the pipe end. The O-ring is attached to the seal groove. D2 representing a diameter of a cylindrical portion defined by a bottom surface of the seal groove and D3 representing an inner diameter of the O-ring with no load satisfy a relationship of D2>D3. D1 representing an outer diameter at the pipe end of the pipe-shaped portion and D2 satisfy a relationship of D1<D2. |
