Abstract
The utility model relates to an interchange type pneumatic one-way valve, which comprises a cylinder body, an air cylinder upper cover, an air cylinder lower cover, a support, a valve seat, a piston rod, a valve rod and a valve clack. The air cylinder upper cover and the air cylinder lower cover are arranged on the upper portion and the lower portion of the cylinder body through thread connection. The support is arranged on the lower portion of the air cylinder lower cover in thread connection mode, the valve seat is arranged on the lower portion of the support in thread connection mode, and the piston rod, the valve rod and the valve clack are arranged in the cylinder body, the support and the valve seat through threads in sequence. The air cylinder upper cover and the cylinder and the air cylinder lower cover and the support are both connected through threads, and accordingly the interchange type pneumatic one-way valve can be changed into normal close type or normal open type pneumatic one-way valve according to requirements. A 2-shaped sealing ring is adopted to replace an existing O-shaped sealing ring, thereby enabling width of a mounting groove on a piston to be reduced by nearly a half and reducing production cost.
