Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of pneumatic power actuator, concretely to quick dismounting type pneumatic power actuator. BACKGROUND

[0002] The design of reciprocating push as an actuator is relatively common in various devices, especially the actuator of a valve. In the valve, the actuator of a straight stroke regulating valve is divided into pneumatic, electric and hydraulic, and in the pneumatic, there are cylinder type and diaphragm type. The traditional diaphragm type generally uses a spring as a reset element. As known, the control valve operates frequently, and the reset element of the pneumatic actuator is required to have high stability and reliability.

[0003] For example, the patent with the announcement number CN205978751U and the authorized patent name (actuator powered by air) in China comprises: a first air chamber and a second air chamber; and a push rod provided in the first air chamber or the second air chamber and penetrating to the outside of the air chamber. The pressure difference between the first air chamber and the second air chamber can cause the air chamber where the push rod is located to at least reversibly deform along the axial direction of the push rod to drive the push rod to move in two directions. The actuator powered by air based on the above design is applied to a valve to realize the function of springless reset, overcome the short board of the traditional spring as the reset element of the valve actuator, realize reset through the air pressure of the air chamber, and has high reliability of return. In addition, because the spring is cancelled, maintenance caused by replacement of the spring is avoided, the continuous working period of the control valve is long, the service life is increased, and the actuator is also applicable to other application fields of the actuator for regulating straight stroke and has the same advantages.

[0004] However, the existing pneumatic power actuator is large in size, which causes complicated installation and dismounting operation in use, and low efficiency of equipment carrying and moving. Therefore, the existing demand is not met, and the quick dismounting type pneumatic power actuator is proposed. UTILITY MODEL CONTENTS

Then, the internal gas of the suction cup is squeezed out at the contact point. By rotating the rotating threaded rod, the space position of the suction cup is lifted upward, thereby creating a relative negative pressure inside the suction cup, which improves the installation stability. This effectively avoids the problem of cumbersome installation and disassembly operations and low efficiency in equipment handling caused by the large size of existing pneumatic power actuators.
