Document Type and Number:
Japanese Patent JPH04158222
Kind Code:
A
Abstract:
PURPOSE:To unify the types of an apparatus and to simplify assembly thereof by providing thread holes for a flange joint in flange surfaces of a casing and internal threads for a screw joint inside an inflow port and an ouflow port and by applying the apparatus to either a piping connection system of the flange joint or the one of the screw joint. CONSTITUTION:Internal threads 11 and 12 for a flange joint are provided in flange surfaces 9 and 10 of a casing 1, while internal threads 13 and 14 for a screw joint are provided in the inner peripheral surfaces of an inflow port 5 and an outflow port 6. In the case of connection with a piping of the flange joint, the flange part of the piping of the flange joint is made to abut each of the flange surfaces 9 and 10 and external threads are screwed in the internal threads 11 and 12 for flange joint, so that the connection be attained. In the case of connection with a piping of the screw joint, on the other hand, external thread parts for the screw joint of the piping of the screw joint are screwed in the internal threads 13 and 14 for the screw joint respectively, so that the connection be attained. In this way, an apparatus can be made to meet either a piping connection system of the piping of the flange joint or the connection system of the piping for the screw joint.
