Description

Technical Field

[0001] The utility model relates to the technical field of electric actuators, in particular to an electromechanical separation electric actuator. Background Art

[0002] An electric actuator is an automation device that uses electricity as a power source. It is usually used in mechanical systems to control and perform specific actions. The electric actuator can receive signals from the control system and drive mechanical components such as valves, doors, lifting platforms, etc. to switch, adjust or move according to these signals.

[0003] In the existing technology, electric actuators are generally used as electric devices for valves when used in pipelines. The existing related equipment is generally directly connected. Once an accident occurs, it is necessary to disconnect the connection between the actuator and the valve before the valve can be closed urgently, which is easy to cause mistakes in emergency situations. Based on this problem, we propose an electromechanical separation electric actuator. Utility Model Content

When the positioning holes at the corresponding positions coincide, connecting bolts are provided through the two positioning holes, and the side walls of the connecting bolts are threaded with matching fastening nuts.

[0009] Preferably, anti-slip pads are provided on the inner walls of the two connecting sleeves.

[0010] Preferably, a rotating handle is fixedly connected to the outer side wall of the valve stem.

[0011] Preferably, the two connecting columns are both L-shaped, and the two connecting columns are arranged on both sides of the valve body.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] In the utility model, by arranging the fixing device and the connecting device to cooperate with each other, when the actuator fails, the corresponding connecting bolt can be directly pulled out, and the valve stem can be directly driven by external force by turning the handle, which can increase the fault tolerance rate in unexpected situations. The actuator body and the valve body are connected by a connecting sleeve, and are not directly connected to the valve body, which will not damage the main structure of the valve body and is also convenient for disassembly.
