| 摘要 |
The present invention relates to a reducing valve which reduces a pressure on the primary side to a predetermined pressure on the secondary side by changing the opening of a valve head with the energy of a fluid itself which passes through. A movable wall of an operating section and an operating rod for transmitting the displacement of the movable wall to the valve head are connected by a curved wall comprising a nearly semispherical surface expanding outwardly in the diametrical direction of the operating rod or a plurality of curved surfaces. |
