Abstract

The invention relates to a compact double-buffering-piston rapid executing mechanism. The compact double-buffering-piston rapid executing mechanism comprises an upper cylinder cover, a lower cylinder cover and a piston, wherein the piston is arranged in a cylinder block. The compact double-buffering-piston rapid executing mechanism is characterized by further comprising a buffer plunger, a first buffer shaft sleeve, a second buffer shaft sleeve and a lower plunger type push rod; the first buffer shaft sleeve is arranged on one side of the cylinder block and connected with the upper cylinder cover through a bolt; the outer side of the buffer plunger is provided with a first cylindrical step which is in sliding fit with an inner round cavity of the first buffer shaft sleeve; the lower plunger type push rod is arranged on the other side of the piston and sleeved with the second buffer shaft sleeve, and the end portion, close to one side of the piston, of the second buffer shaft sleeve is provided with a second cylindrical step; the second cylindrical step is in sliding fit with the inner round wall of the second buffer shaft sleeve. The compact double-buffering-piston rapid executing mechanism is compact and light in structure, and a double-direction buffer function can be achieved without any other additional intervention; equipment abnormity and damage caused by rapid and frequent actions can be effectively avoided.

Description

technical field [0001] The invention relates to an actuator, specifically a piston-type fast-acting actuator with compact structure and bidirectional buffer function. Background technique [0002] As a driving device, the piston-type linear pneumatic actuator has already possessed quite mature technical conditions and perfect production and assembly processes. Especially as a kind of application of control valve actuator, it has been very extensive. For example, pneumatic single-seat control valves, pneumatic angle valves, pneumatic sleeve-type control valves, pneumatic gate valves and other valves, and piston-type linear pneumatic actuators are widely used. Due to the continuous upgrading of science and technology, the production process is also undergoing continuous technological innovation. The development of control valves plays a vital role in the process of this technological innovation. [0003] As an industrial catalyst and industrial raw material, oxygen is widely...
