Description

Electronic return switch for valves

The present invention relates to an electronic return device for a valve, and more particularly, even when a power failure occurs by rotating the opening and closing of the valve body through a gear unit which is driven by a motor driven by a rechargeable battery provided on a PCB substrate provided inside the case part. The present invention relates to an electronic return device for a valve capable of opening and closing a valve with power of a rechargeable battery and of controlling a flow rate in proportion.

In general, like a gas valve, the user can open and close it immediately when he wants. However, many devices are used to open and close electronically by connecting with electronic controllers such as boilers, air conditioning and heating systems.

Accordingly, electronic devices have been developed with various forms and operating structures depending on the type of valve.

Referring to Patent No. 10-0477002 as an example of such a conventional electronic valve, the valve body having an inlet and an outlet is formed, and an electromotive force is generated in the coil by an externally applied power source to open or shut off or maintain a moving plunger for opening and closing the valve. The automatic valve opening and closing portion and the manual valve opening and closing portion for manually opening or closing the moving plunger in case of power failure.

The automatic valve opening and closing portion of the conventional electromagnetic valve configured as described above moves up and down between the inlet and the outlet of the valve body by a vertical movement action of a moving plunger having a shaft integrally connected to the upper end of the diaphragm connected to the upper end of the shaft. Open or shut off.

At this time, the movable plunger moves up and down as the coil generates electromotive force by externally applied power, and in case of power failure or emergency, the moving plunger moves upwards by a restoring spring installed at the lower end of the shaft, or automatically shuts off the valve. The valve is opened or closed by forcibly moving up and down by forcibly moving the shaft up and down by manual operation of the manual operation lever of the manual valve opening and closing portion extending from the upper side of the plunger.

Only work.

However, such a conventional electronic valve continuously supplies external power so that the coil generates an electromotive force while the shaft is moved up and down by the vertical movement action of the movable plunger to maintain the valve open or valve shut off. Consumption also has a disadvantage.

In particular, there was a problem that it is difficult to immediately open or shut off the valve in case of power failure or emergency by manual operation.

The present invention has been made in order to solve the conventional problems as described above, the user can be operated manually as well as having a rechargeable battery inside the device, such as a ball valve by a motor driven by the rechargeable battery in an emergency state such as power failure The opening and closing of the valve can be opened or closed by automatically or manually rotating the valve, and when the electricity is applied, it is operated by the applied electricity so that the valve can be operated immediately even in the event of a power failure.
