Description

ELECTRIC ACTUATOR FOR BALL VALVE

The present invention relates to an electric ball valve for automatically opening and closing the ball valve 30 using AC power, which can open and close the ball valve 30 using AC power on the top of the ball valve 30. The electric opening and closing device 10 is installed, and the electric opening and closing device output shaft 13 is connected to the stem 31 which is the rotating shaft of the ball 32 of the ball valve 30. By arranging the electric motor 12, the limit switches 15a and 15b, and the PCB 16, the user can conveniently open and close the ball valve 30 automatically, as well as blocking AC power or failure of the electric ball valve. In the same emergency, the user is designed to enable manual operation so that the user can manually open and close the ball valve 30 manually.

The present invention relates to an electric ball valve that can automatically open and close the ball valve 30 by using the AC power in detail can be opened and closed by using the AC power directly without a separate power supply device, The present invention relates to an electric ball valve configured to allow a manual operation by a user in the event of an AC power interruption or an electric ball valve failure.

In general, the conventional electric ball valve was configured to open and close the ball valve using a DC motor mounted inside the electric ball valve. Accordingly, in order to supply the DC power to the DC motor, there was a need to attach a power supply device that converts external AC power to DC power inside the valve. Therefore, the structure of the product is complicated and the manufacturing difficulties. This adds a power supply inside the electric ball valve, which increases the number of parts and complicates the assembly process, which causes a lot of difficulty in the manufacturing process, increases manufacturing costs, and unnecessarily increases the size of the product.

And when it is difficult to attach the power supply inside the electric ball valve, the electric ball valve was configured by adding a product that supplies power by converting a separate AC power into DC power. This phenomenon was unreasonable to add a separate power supply in addition to the electric opening and closing device to open and close the ball valve.

In the case of the conventional electric ball valve, the power supply is cut off or the manual operation is not possible in case of an emergency such as a malfunction of the electric ball valve. This may provide the cause of the secondary damages in case of emergency or quick action due to the failure of the electric ball valve. Therefore, in order to solve this problem, the manual installation of the electric ball valve and Additional valves were installed to enable emergency use, which unnecessarily increased costs. This phenomenon had a problem of reducing the reliability of the electric ball valve in an emergency.

An object of the present invention has been researched and developed in order to solve the above-mentioned conventional problems, it is generally configured to open and close the ball valve using a DC motor mounted inside the electric ball valve in the case of the conventional electric ball valve. . Accordingly, in order to supply the DC power to the DC motor, there was a need to attach a power supply device that converts external AC power to DC power inside the valve. Therefore, since the structure of the product is complicated, it acted as a difficulty in manufacturing. This adds a power supply inside the electric ball valve, which increases the number of parts and complicates the assembly process, which causes a lot of difficulty in the manufacturing process, increases the manufacturing cost, and unnecessarily increases the size of the product.

And when it is difficult to attach the power supply inside the electric ball valve, the electric ball valve was configured by adding a product that supplies power by converting a separate AC power into DC power. This phenomenon was unreasonable to add a separate power supply in addition to the electric opening and closing device to open and close the ball valve. In addition, the present invention provides an electric ball valve capable of manual operation so that a user can open and close the ball valve manually in an emergency such as an AC power interruption or a failure of the electric ball valve.

The present invention was developed in view of the conventional problems, the upper end of the ball valve 30 is provided with an electric opening and closing device 10 and a swing plate between the electric opening and closing device 10 and the ball valve 30. 21, a slide plate 22, a fixed plate 23, and directly supply AC power to the power wire 11 of the electric opening and closing device 10 side.

The slide plate 22 is fixed to the fixed plate 23, the swing plate 21 is fixed to the electric opening and closing device (10). When the manual lever 24 is pulled and the electric opening / closing device 10 is rotated during the manual operation, the swing plate 21 attached to the top of the slide plate 22 attached to the fixed plate 23 rotates and the ball valve ( Manual operation of 30) becomes possible.

The electric ball valve is provided with an electric motor 12 inside the electric opening and closing device 10 of the upper end of the ball valve 30 to open and close the ball valve 30 automatically. ) To supply AC power directly.

The swing plate 21 is attached to the electric opening and closing device 10, the fixed plate 23 is attached to the ball valve 30 and the slit plate 22 is attached to the fixed plate 23.

When the manual lever 24 is pulled in order to manually operate the ball valve 30 in case of emergency, such as the interruption of the AC power supply or the failure of the electric ball valve, the internal fixing pin 25 is separated from the swing plate 21. Rotation is possible between the swing plate 21 attached to the opening and closing device 10 and the slide plate 22 attached to the fixed plate 23. When the electric opening and closing device 10 is turned by hand while the manual lever 24 is pulled, the electric opening and closing device output shaft 13 inside the electric opening and closing device 10 is connected to the stem of the ball valve 30. 31 rotates and the stem 31 rotates the ball 32 of the ball valve 30 so that the ball valve 30 can be opened and closed.

When the manual lever 24 is released after the manual operation is completed, the fixing pin is fixed to the hole in the open position or the closed position prepared by the swing plate 21 and the manual operation ends.

The present invention has been developed in view of the conventional problems, it is possible to open and close the ball valve 30 by using the external AC power directly without a separate power supply device to simplify the structure of the product, it is easy to manufacture. In addition, the ball valve can be opened and closed with a small electric opening and closing device 10, and the manufacturing cost is lowered.

Since unnecessary devices and external power supply are eliminated, installation and use of electric ball valve is simplified.

In addition, manual operation is possible in case of emergency such as power supply cut off or electric ball valve failure, so that quick action is possible in case of problems. When the power supply is cut off or the electric ball valve is broken, the user can manually open and close the ball valve 30 manually by rotating the electric opening and closing device 10 while pulling the manual lever 24. It reduces the possibility of secondary damage and reduces the cost because it does not need to install a manual valve for a separate manual operation in the pipe line in which the electric ball valve is mounted, thereby reducing the cost and increasing the product reliability of the electric ball valve.
