PURPOSE:To facilitate the mounting, maintenance and management of a switching valve by a method wherein a sub-body, equipped with a screw hole for attaching a pipe and a port communicating with the hole, is connected to a piping and the switching valve is mounted onto the sub-body by screwing it. CONSTITUTION:In order to mount a switching valve A to a piping system, the switching valve A is positioned on a sub-body B attached to the pipes in piping system by means of screw holes 18, 19 for attaching the pipes beforehand. That means that the flat lower surface 2 of the switching valve A is set correctly on the flat surface 3 of the sub-body B and the ports 4, 12 and 5, 13 are communicated. The both of the members are clamped by means of bolts for fixing them. When the switching valve A is desired to be taken off, it may be done simply by removing the bolts for fixing. |
