Description

Electric actuator open / close notification system for valves

[0001] The present invention relates to an electric actuator open / close notification system for a valve that provides external information on whether a valve blocking plate that opens or blocks the flow of fluid is open or closed in conjunction with a valve tube.

[0002] In general, piping equipment for the transport of fluids is very important in terms of controlling the temperature, pressure, and flow rate of the fluid, and this is achieved by valves installed at necessary locations in the piping.

[0003] These valves are devices that control and block the flow of fluids, and are classified by purpose, specifications, materials, and structures. There are small household valves and large industrial valves that are used as various important components across industries, from petrochemicals, oil refining, and shipbuilding.

[0004] Meanwhile, a valve capable of implementing an opening and closing function for connecting and blocking the flow is equipped with a valve position indicator that indicates the position of the valve (disk opening rate).

[0005] Conventional valve position indicators are linked to the rotational axis of the valve and simply indicate whether the fluid path passing through the valve is opened or closed by the valve disc according to the forward and reverse rotation of the rotational axis of the valve.

[0006] In addition, in a 3-way valve with three channels, such as a 'T' type valve or a 'Y' type valve, there is a problem in that the conventional valve on / off position indicator, which only indicates whether the valve is open or closed, cannot properly indicate the direction of fluid flow.

[0007] The present invention is intended to solve the problems of the prior art and has the following objectives.

[0008] The purpose of the present invention is to provide an electric actuator opening / closing notification system for a valve, which provides information on whether the valve is turned on / off by the operation of the actuator and emits LED light in a segmented manner so that the operation can be clearly confirmed with the naked eye.

[0009]

[0010] Meanwhile, the technical tasks to be achieved in the present invention are not limited to the technical tasks mentioned above, and other technical tasks not mentioned can be clearly understood by a person having ordinary knowledge in the technical field to which the present invention belongs from the description below.

[0011] The present invention achieves the above object by including an actuator that operates a valve in conjunction with the valve, an LED board provided on the outer periphery of a rotational shaft of the actuator and having LEDs provided in a cross shape, an information providing unit that is installed in conjunction with the rotational shaft and has a cross-shaped partition formed on the upper end and the outer periphery and has a recognition plate installation unit for fastening a recognition plate, a recognition plate installed on the recognition plate installation unit, an open / close notification unit that is partially closed and partially opened to externally display whether the valve is on or off according to the rotational operation of the information providing unit, and a casing made of a transparent material that surrounds the information providing unit and the open / close notification unit and is fastened to the upper part of the actuator.

[0012]

[0013] The recognition plate installation part of the above information provision unit is formed with a groove to accommodate the recognition plate, and a protrusion and a fitting groove are formed to fix the recognition plate assembled with the outer surface and the upper surface.

[0014] The lower surface of the above recognition plate is characterized by having a groove corresponding to the protrusion and a projection formed on the inner upper side to fit into the fitting groove.

[0015]

[0016] The feature is that fastening grooves are formed at equal intervals on the inner side of the casing, and fastening projections are formed at equal intervals on the outer periphery of the open / close notification unit, so that the open / close notification unit is assembled to the inner side of the casing.

[0017]

[0018] The inside of the compartment provided in the shape of a cross in the above open / close notification section is characterized by having a guide hole that guides LED light to the compartment.

[0019]

[0020] The above-mentioned induction hole is characterized by having a diffusion member at the entrance to diffuse the LED light.

[0021] As described, according to the present invention, the LED light is emitted in a segmented manner as an information providing unit that provides whether the valve is turned on / off by rotation by the operation of the actuator, so that it is clearly a very useful invention that provides an effect of clearly confirming with the naked eye whether the valve is in operation from a distance.

[0022]

[0023] Meanwhile, the effects that can be obtained from the present invention are not limited to the effects mentioned above, and other effects that are not mentioned can be clearly understood by a person having ordinary skill in the technical field to which the present invention belongs from the description below.
