Abstract
The utility model relates to a small pneumatic soft sealing single-seat regulating valve. The small pneumatic soft sealing single-seat regulating valve is characterized by being formed by a pneumatic membrane spring actuator and a low-choked-flow soft sealing cut-through single-seat regulating mechanism. A pneumatic actuator is arranged on the upper portion of a valve body and is fixedly connected with an upper valve deck through a connecting nut, a support, double-end studs and hexagon nuts, and a packing gland, an upper packing pad, packing, a lower packing pad and a packing spring are sequentially arranged in the upper valve deck to form the pneumatic membrane spring actuator. A valve element is arranged on a valve seat and is in sealing connection with the valve body through a valve body sealing gasket, and the upper valve deck is fixedly connected with a valve element component through double-end studs, hexagon nuts, an upper sealing gasket, a guiding cover and a lower sealing gasket in a sealed mode to form the low-choked-flow soft sealing cut-through single-seat regulating mechanism. The small pneumatic soft sealing single-seat regulating valve has the advantages of being reasonable in design, simple in structure, small in size, light in weight, high in flow rate, tight in sealing, applicable to occasions where requirements for the high flow rate and the leakage rate are restrict, and the like.
