Because the valve core is eccentric, the other side of the valve plate in the valve cavity interferes with the inner wall of the valve cavity and cannot swing, so that the opening and closing modes of the existing cam deflection valve are differentiated in the forward direction and the reverse direction, namely, the valve plate is opened clockwise and closed anticlockwise or closed clockwise and opened anticlockwise, and only one of the valve plate and the valve plate is available. The cam flexing valves adopting different opening and closing modes cannot be used commonly, otherwise, not only the logic control mode of an actuating mechanism connected with the cam flexing valves needs to be changed completely, but also the original position of the actuating mechanism needs to be adjusted generally, even the actuating mechanism needs to be displaced integrally, and the workload is increased greatly. In the practical application process, the damage or the fault of the valve is often just the same, and the valve often has to be purchased in an emergency way on the market to avoid long-time production interruption under the condition of no stock, and the available products are often different from the original opening and closing way of the valve. In view of this, cam flexing valve users desire the market to be able to provide a cam flexing valve that can be easily interchanged in both forward and reverse directions. Utility model patent application with publication number CN203857121U discloses a cam flexure valve in 2014 10 month 1, including case, soft sealing disk seat, the case is eccentric case, is provided with the recess on the disk seat, fixes being provided with plastic sealing material on the recess, plastic sealing material and case interference fit.
