<P>PROBLEM TO BE SOLVED: To provide a soft seal partitioning valve, which is capable of being used while improving leachability by reducing a contact area of a rubber seal material to fluid, and at the same time capable of suppressing the peeling of carbon by the degradation of rubber, and which surely prevents fluid leakage and prevents the excessive fastening of a valve body by exhibiting high sealsability while preventing the coming-out of the rubber sheet by firmly attaching the valve body and the rubber a sheet without using adhesive with high accuracy. <P>SOLUTION: The soft seal partitioning valve opens and closes a flow path 5 of a valve box 2 by sealing a valve seat part 6 and a water stop surface 7 arranged in the valve box 2 by the valve body 1 moving up and down in a crossing direction to the flow path 5 in the valve box 2. In the valve body 1 of the soft seal valve, a rubber lightning is applied to the rubber fixed part 16 arranged in the upper arc site and the lower arc site of the upstream side surface 13 and the downstream side surface 14 of the matrix 10, and the valve body seal part 31 for sealing the valve seat part 6 and the water stop of part 32 pressedly sealing the water stop surface 7 are arranged, respectively. <P>COPYRIGHT: (C)2013,JPO&INPIT |
