PURPOSE:To obtain a reliable testing device substantially without any trouble such as cracks, etc., in a welded part by communicating a main communication hole with a branch hole within a valve body and making the branch hole to freely open and close. CONSTITUTION:A valve 8 for pressure resistance test forms a valve part mounting hole 3 perpendicular to a main communication hole 2, and a valve part 5 of manually opening and closing type provided with a needle 4 is fitted to the valve part mounting hole 3. A testing device is provided with two or more of such valves 8 for pressure resistance testing device as above, and allows each valve 8 for pressure resistance testing device to be mounted to a movable body frame 9. Simultaneously, both ends of a connecting pipe 10 are connected to the valve 8 for pressure resistance testing device such that mutual communication may be provided between the respective communicating holes 2. Further, at least one connecting part for a pressure fluid source capable of connecting the ends of a pipe or a hose connected to said pressure fluid source is provided on a piping connecting part 6. |
