Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings.

[0025] Such as Figure 1 to Figure 9 , a remote electronic lock and mechanical lock coexistence structure of an electric actuator in the present invention, including an electric cover 1, a knob 2, a knob stopper 5, a torsion spring 6, a padlock 7, a magnetic steel 9, a display module 10, and a magnetic control switch 11 And main control module 12.

[0026] Knob 2 is rotatably connected to electrical cover 1. Rotate knob 2 and place the electric actuator in STOP, REM and LOC positions. Knob block 5 passes through torsion spring 6 and is rotatably connected to electrical cover 1. The torsion spring One free end of 6 is in contact with the electrical cover 1, and the other free end is in contact with the knob stopper 5. Pull the knob stopper 5 and make the knob stopper 5 overcome the elastic force of the torsion spring 6 to move one end of the knob stopper 5. It is clam...

Abstract

The invention discloses a coexistence structure of a remote electronic lock and a mechanical lock of an electric actuator. The knob is rotatably connected to the electric cover, and the knob is rotated and the electric actuator is correspondingly placed in STOP gear, REM gear and LOC gear. Pass the torsion spring and rotate it to connect to the electrical cover. One free end of the torsion spring is in contact with the electrical cover, and the other free end is in contact with the knob stopper. Pull the knob stopper and make the knob stopper move against the elastic force of the torsion spring. Set one end of the knob stopper on the knob and limit the movement of the knob, lock the padlock on the knob stopper and limit the return of the torsion spring; several magnetic control switches are set in the electrical cover, and the two magnetic control switches are correspondingly placed in STOP On the gears of the REM gear and the REM gear, the magnetic steel is installed on the knob. The present invention adopts the coexistence mode of the remote electronic lock and the mechanical lock, the two modes coexist completely independently, redundant design, the remote electronic lock and the mechanical lock can be selected arbitrarily, coexist independently, and improve safety.

Description

Technical field: [0001] The invention relates to a coexistence structure of a remote electronic lock and a mechanical lock of an electric actuator. Background technique: [0002] Electric actuators, also known as actuators, are widely used in valve pipeline control. Existing electric actuators generally have three modes: "remote", "stop", and "on-site", and the mode switching is realized by a knob or a button. After on-site debugging, the electric actuator is connected to the entire control system. In order to prevent the actuator from being misoperated in the field, it is required that the actuator can be safely kept in the "remote" mode. [0003] Most of the existing electric actuators use padlocks perforated on the buttons or knobs, so that the actuators are "locked" in the "remote" mode. The way of perforated padlock affects the overall style of the actuator in appearance, and the mechanical padlock with simple function may be exposed to the external environment for a ...
