PROBLEM TO BE SOLVED: To provide a connector member for a pipeline block showing a superior pressure resistance and superior sealability and a pipeline connector structure of pipeline block using the connector member.SOLUTION: Pipelines 31, 41 in pipeline blocks 3, 4 are connected by a connector member 1. The connector member 1 has a hollow tubular part 10 molded through an injection molding of synthetic resin, and an outer circumference at a central part of the tubular part is provided with a disc-like flange 11. There are provided a pair of cylinder parts 12, 12 to hold the flange 11 and the outer circumferences of the cylinder parts 12, 12 are formed in a substantial flat cylindrical surface. The connector member 1 has a pair of O-rings 2, 2 installed at an outer circumference of the cylinder part to hold the flange 11. The pair of O-rings 2, 2 are installed at positions where they are substantially contacted with the flange 11. An outer diameter of the flange 11 is set to be smaller than outer diameters of O-rings 2, 2.SELECTED DRAWING: Figure 2 |
