<p>PURPOSE:To form a branching sectiong easily near a gate valve by forming a connecting section with the gate valve at one end of a short pipe consiting of a thermoplastic resin and the branching sectiong to an outer circumferential surface in a vacuum type sewarage system. CONSTITUTION:A member 1 for connecting a gate valve is made abut against the flange surface 31 of the interval valve 3 of a vacuum type sewarage system through a flange surface 11. The flange surface 31 and the member 1 are clamped and fixed with bolts 2. On the other hand, a pipe body 8 with a socket 81 is connected to the other end section side of the membr 1 for connecting the gate valve, and a piping is executed. The length size of the member 1 for connecting the gate valve is shortened, the member 1 is brought to the state, in which the member 1 is bonded previously the gate valve 3, and the member 1 for connecting the gate valve may also be arranged in a manhole 9, etc., together with the gate valve. A valve 5 and a desired member such as a pressure sensor are bonded with the branch pipe 12. Acoordingly, the forming operation of the branch pipe 12 particularly in a narrow space such as the manhole 9 is facilitated.</p> |
