Detailed Description

The following description of the adjustable column stroke actuator according to the present invention is made with reference to the accompanying drawings, and the following embodiments are exemplary and not intended to limit the technical scope of the invention.

Referring to fig. 1 to 3, an adjustable column stroke actuator, including cylinder 1, pneumatic cylinder 2, pneumatic cylinder connecting rod 3, connecting axle 4, pneumatic cylinder 2 sets up in the upper end of cylinder 1, pneumatic cylinder 2 is connected to the upper end of pneumatic cylinder connecting rod 3, the lower extreme runs through cylinder 1 and connects connecting axle 4, the lower extreme of cylinder 1 is equipped with stand 5, the lower extreme of stand 5 is equipped with flange joint board 6, flange joint board 6's center is equipped with stop collar 7, cylinder 1 includes cylinder liner 11, cylinder bottom plate 12, cylinder top cap 13, piston 14 and spring 15, be equipped with uide bushing 16 on the cylinder bottom plate 12.

Preferably, the number of the upright posts 5 is two. The column 5 is provided with a mounting hole 51 extending in radial length. The installation space between the actuating mechanism and the valve body is increased, the valve auxiliary can be installed, and the space required by the overall installation of the valve is reduced.

Preferably, a guide ring 17 is provided outside the piston 14. The consumption speed of the cylinder sleeve 11 and the piston 14 can be effectively reduced, and the service life is prolonged.

When the actuator is assembled, the hydraulic cylinder connecting rod 3 penetrates through the guide sleeve 16 on the cylinder bottom plate 12, the piston 14 is arranged in the cylinder 1 and is connected with the hydraulic cylinder connecting rod 3, the cylinder bottom plate 12 and the cylinder top cover 13 are tightly pressed at two ends of the cylinder sleeve 11 through bolts to form sealing, the hydraulic cylinder 2 is connected with the cylinder top cover 13 through the connecting support, the hydraulic cylinder 2 is connected with a hydraulic system, the lower end of the cylinder bottom plate 12 is provided with the upright post 5 in a threaded connection or fixing way, the lower end of the upright post 5 is connected with the flange connecting plate 6, the flange connecting plate 6 is connected with the valve body, a first fixing hole 61 for connecting the upright post, a second fixing hole 62 for connecting the valve body and an annular limiting step 63 for assembling the limiting sleeve 7 are drilled on the flange connecting plate 6, the first fixing hole corresponds to the upright post 5, the second fixing hole 62 corresponds to a connecting hole at the, The number and the size of the connecting shaft 4 are changed, the connecting shaft 4 is connected with the hydraulic cylinder connecting rod 3 through a cylindrical pin and a split pin, and the mounting hole 51 is used for fixing accessories such as instruments and inductors or mounting and fixing a bracket for the accessories.
