For achieving the above object, the technical solution adopted in the utility model is: a kind of pin column type butterfly plate linkage structure, butterfly plate is provided with in valve body, described butterfly plate side is connected with live axle, described butterfly plate linkage structure comprises: described live axle and described butterfly plate side are with the gudgeon of axis hole, it is characterized in that, the free end of described live axle is provided with the first half grooves, the inwall of described gudgeon is provided with the second half grooves, when the free end of described live axle is inserted in described axis hole, described the first half grooves and described the second half grooves form the pin-and-hole of cylindricality jointly, pin is provided with in described pin-and-hole.
In the utility model preferred embodiment, described live axle dual-side is respectively provided with described the first half grooves, puts corresponding position with two described the first half slots, and the sidewall of described axis hole is also provided with two described the second half grooves.
In the utility model preferred embodiment, described the second half groove one end are run through inside and outside described axis hole, and described the second half grooves are provided with opening at described sidewall.
In the utility model preferred embodiment, described butterfly plate circumference rounds retainer, and described retainer covers just at described opening.
In the utility model preferred embodiment, screw runs through described retainer, and is stretched in pin-and-hole by described opening and be threaded with described pin.
In the utility model preferred embodiment, being inserted in described axis hole of described live axle circumferential size interference.
The utility model solves the defect existed in background technique, the utility model utilizes two pins to be inserted in, and live axle and butterfly plate are fixed by structure that gudgeon internal fixtion lives live axle, when rotated, its torque force rotated carries by pin live axle, and linkage structure is comparatively stable; And pin inserts the installation method fixed drive axle comparatively simple and fast in pin-and-hole; The opening of pin-and-hole can seal by retainer, avoids the infiltration of fluid, and simultaneously live axle and axis hole interference is socketed, and a large amount of infiltrations that said structure it also avoid fluid cause the corrosion of linkage structure.
