In this case, by supplying an amt. of hot water more than that of the capacity of the tank, it is allowed to overflow forcibly from an overflow tube 108. At that time, filth whose specific gravity is smaller than '1' is discharged to the outside together with overflowing hot water. Subsequently, hot water in the tank 100 is set to a static state for a prescribed time and filth whose specific gravity is larger than '1' is settled on a bottom part of the tank. Next, by opening a gate valve 106, the settled filth is discharged together with hot water in the lower part of the tank through a drain tube 104. Thereafter, a physically handicapped person is moved into a bathtub main body 5 together with a bathing chair, and by driving the pump 206, hot water in the tank 100 is returned to the bathtub main body 5.

Filed: 1991-12-30
Abstract: PURPOSE:To provide a relief valve where a free piston can always be returned to its original position, where the free piston is easily disposed in the relief valve of a pilot operating type. CONSTITUTION:When a surge pressure is generated on a first inlet/outlet port 22 side, a pilot seat member 30 is moved together with a pilot poppet 38 against a second spring 39.
