An actuator operating state light emitting display device.

In general, actuators used to open and close valves such as butterfly valves and ball valves, and rotary devices such as dampers are operated by an electrical signal input from the outside, and the electrical signals are generally transmitted through a micro switch. The valve and the rotary device are opened and closed by rotating the motor or manually in the range of about 90 °.

In addition, these actuators have a self-locking device with dual worm gears, manual and electric mode switching devices, overload and overcurrent protection devices, and condensation and condensation water protection to prevent rotation by reverse torque transmitted from the valve. Built-in heater, etc. for maintaining the optimum operating state at all times.

Dual, manual and electric mode switching device is a device that can open and close the valve by selecting any one of the power of the motor or the handle manual operation in opening and closing the valve or rotary machine, depending on whether the manual / motor mode switching Opening and closing can be performed by motor power or by hand. After the manual / full operation, the user checks the normal operation. This is the operation status display window.

Existing display devices are coupled to the transparent display window 20 in the housing 1, as shown in the plan view of Figure 1a and cross-sectional view of Figure 1b, the lower portion of the display window 20 to accommodate the light emitting lamp 11 ( 10) of course. Of course, the indicator 10 is configured in the form of opening and closing the valve lever in conjunction with the valve lever, it is coupled to the upper end of the valve lever.

However, this method has a problem that it is difficult to easily identify whether the actuator is in an open state or a closed state other than the upper portion of the housing 1 or the display is small.

Electric actuator configured to include a secondary worm shaft portion 80 to

A motor 20 as a driving source;

2 for rotating the secondary worm wheel 70 fixed to the secondary worm shaft 71 which is the final power shaft for receiving the power from the motor 20 through the power transmission means and coupling the valve lever 303 to the lower end. In the electric actuator configured to couple the secondary worm shaft portion 80 having the primary worm 81 to the housing 300,

A domed opening and closing indicator 312 in which the opening and closing indicators are alternately arranged at a predetermined angle on the side and the upper surface of the lower open cap which is integrally coupled to the upper portion of the secondary worm shaft 71;

A transparent display window 311 protruding in a dome shape on the upper surface of the housing 300;

The open window 313-1 is fixed to the inner surface of the transparent display window 311 so that the open position of the open and close indicators 312 of the opening and closing indicators 312 is visible through the transparent display window 311. It comprises a opening and closing window 313 arranged in a mutually staggered vertical position.

The opening and closing indicator 312 is composed of a cylindrical vertical wall (312-1), and an upper surface (312-2) blocking the upper portion of the vertical wall (312-1), the vertical wall 312-1 is centered in the middle The upper and lower parts are divided into upper and lower display parts L1 and L2 which display different states, and the display part of the same state is displayed on the opening window 313.

The opening and closing window 313 is opposite to the upper and lower portions at intervals of 90 degrees, so as to form the opening window 313-1 at a position corresponding to the boundary reference line P of the upper and lower display portions L1 and L2 of the opening and closing display opening 312. Configure.

As an example of the configuration of receiving the power of the motor 20, the secondary worm shaft 71 directly connected to the valve and the secondary worm wheel 70 for transmitting power to the worm shaft are coupled to the upper open housing 300 forming the actuator exterior. Make up,

Internal body consisting of a second worm shaft portion 80 for transmitting power to the secondary worm wheel 70, and a motor 20 for transmitting power to the secondary worm shaft portion 80 through the power transmission means (in one body) 320 is detachably coupled to the housing 300,

The inner body 320 includes a secondary worm shaft receiving hole 329 for guiding the secondary worm shaft 71 to be exposed to the display window 311 portion of the cover.

The inner body 320 has a secondary worm shaft accommodating part 324 for accommodating the secondary worm shaft part 80, and a secondary worm shaft accommodating hole 329 for accommodating a secondary worm wheel 70 installed in the housing 300. The worm shaft receiving portion 322 and the power transmission means 323 for decelerating the power from the motor 20 to be transmitted to the secondary worm shaft portion 80 is coupled to the worm shaft receiving portion 324 It consists of a vertical body 326 integrally formed with the secondary worm wheel receiving portion 322.

The lower end of the secondary worm shaft 71 is coupled to the valve lever 303 to operate with the valve, the upper end of the secondary worm shaft 71 is provided with a light 315 and the opening indicator 312 in sequence. An opening window 313 and a display window 311 are coupled to the cover 310 at an upper portion of the opening indicator 312. The secondary worm shaft accommodating part 324 has a secondary worm shaft accommodating hole 325 in which the tip of the secondary worm shaft accommodating part 80 is exposed.

 The present invention configured as described above has the secondary worm as shown in FIG. 4 through the secondary worm wheel 70 in the secondary worm 81 of the secondary worm shaft part 80 through the power transmission means 323 by the power of the motor 20. The shaft 71 is driven. Here, the driving means that the state of the valve lever 303 shown in FIG. 3 coupled to the lower end of the secondary worm shaft 71 forms a predetermined position (for example, a closed state), and when driven, another position (for example, opens). It means to operate to the state).

In this case, the present invention is the opening indicator 312 shown in the disassembled state in FIG. 5 on the top of the secondary worm shaft 71 as shown in Fig. 3 (coupling method is simply referred to as coupling because it is possible in many ways) On the outer surface of the opening and closing display sphere 312, the upper display portion L1 is displayed upward, and the lower display portion L2 is downward, with the center of the middle reference line P on the vertical wall 312-1. As an example of the notation, the closed display portions a1, a2, a2 '(c1, c2, c2') are spaced apart at an angle of 90 degrees up and down.
