Direct action bellows type gas reducing valve principle and structure description: 1, the valve is composed of valve body, bellows assembly, valve seat, adjusting spring, etc., bellows assembly stem and valve body with the bellows by the medium pressure, push the valve stem shift, change the sealing surface and seat between the distance. 2, when leaving the factory, the sealing surface and the valve seat are closed, when you need to use, by turning the screw clockwise, so that the adjustment spring pressure to the valve stem, top open the sealing surface. When subjected to medium pressure, the medium is divided into two ways, one routes the valve body to the outlet, the other routes the balance hole on the valve body to the inner cavity of the bellows, and makes the valve stem upward and adjusts the balance of the spring force. When the inlet pressure increases, the valve stem of the bellows assembly is shifted upward, the gap between the sealing surface and the seat is reduced, when the balance of the force of the adjustment spring and bellows, the pressure at the outlet is stable on the required value, when the inlet pressure is reduced, the reverse movement is still stable on the required value of the outlet pressure.
