Abstract

The invention discloses an anti-shock buffering mechanism of an angular travel cylinder. The anti-shock buffering mechanism is used for off-positions of butterfly valves and ball valves which act quickly and frequently. The mechanism comprises the cylinder and a box, the box is internally provided with a piston rod connected with the cylinder, one end of the piston rod is connected with a connection block, and the connection block slides on a guide rod. A limiting bolt is further arranged at the end of the box. A blind hole is formed in the connection block and internally provided with a plurality of disc springs. Buffering blocks are arranged in inner circles of the disc springs. Round nuts are further arranged in the blind hole, and the buffering blocks can axially move in the round nuts. According to the anti-shock buffering mechanism of the angular travel cylinder, a disc spring set is adopted as a kinetic energy absorbing and releasing component, the anti-shock and buffering effects are obvious, the buffering stroke is small, and the requirement for quick action can be met. The anti-shock buffering mechanism is simple in structure, required installation space is small, maintenance is not needed, and the mechanism is easy to replace. Design and manufacturing cost is relatively low, and the switching life of the valves and the cylinder can be greatly prolonged.

Description

technical field [0001] The invention relates to an anti-shock buffer mechanism, especially a quarter-stroke cylinder anti-shock buffer mechanism, which has the functions of end position shock resistance and spring buffering, can be installed on the quarter-stroke cylinder, and is used for butterfly valves and ball valves with fast and frequent actions The anti-shock buffer mechanism in the closed position. Background technique [0002] At present, installing a buffer mechanism on the cylinder is a necessary configuration for frequent switching and quick cut-off valve actuators. A cylinder equipped with a buffer mechanism can greatly reduce the wear of the valve seal, prolong its service life, and at the same time extend the life of the cylinder . Especially for program-controlled butterfly valves, program-controlled ball valves and other pneumatic actuators that require frequent switching and quick cut-off, it is even more necessary to be equipped with a buffer mechanism to...
