Description

A butterfly valve bushing press machine

technical field

The utility model relates to the technical field of butterfly valve processing equipment, in particular to a butterfly valve shaft sleeve pressing machine.

Background technique

Butterfly valve is a kind of valve that uses disc type opening and closing parts to reciprocate about 90° to open, close or adjust the flow of medium. Butterfly valve not only has simple structure, small size, light weight, low material consumption, small installation size and small driving torque , The operation is simple and fast, and it can also have good flow adjustment function and closing sealing characteristics. It is one of the fastest-growing valve varieties in the past ten years. The butterfly valve is widely used, and the variety and quantity of its use are still continuing. Expand and develop towards high temperature, high pressure, large diameter, high sealing, long life, excellent adjustment characteristics, and multi-function of a valve, its reliability and other performance indicators have reached a high level, the shaft sleeve is sleeved on the butterfly rod The cylindrical mechanical parts on the valve seat are part of the butterfly valve seat. When processing the butterfly valve, the bushing needs to be press-fitted on the valve seat by a press-fitting machine. The press-in end moves for press-fitting. The output length of the output end of the cylinder is fixed, and the output pressure is not easy to control. When the output pressure of the cylinder is large, it is easy to cause damage to the parts. At the same time, most of the existing butterfly valve bushing presses directly press the valve seat. Placed on the placement plate, the valve seat cannot be effectively fixed during press-fitting, and the valve seat is easy to move, which easily offsets the press-fitting position and affects the qualification rate of butterfly valve processing.
