Abstract

The present invention relates to a portable water supply remote valve control system, and more specifically, to a portable water supply remote valve control system in which, when a water shut-off valve inside a manhole needs to be opened or controlled for opening and closing due to maintenance or cleaning, a worker does not perform the opening and closing operation over a long period of time using an opening/closing rod, but rather transports and fixes a connecting part and a valve operating device in accordance with the installation form of the water shut-off valve, and then controls the operation of an electric motor remotely through the valve operating device to open and close the valve, wherein when the valve is opened, water quality information of the surrounding pipeline is received from the control unit, and the degree of opening and closing or the opening/closing time is controlled according to changes in the surrounding water quality.

Description

Portable water supply remote valve control system The present invention relates to a portable water supply remote valve control system that is installed on a manual valve requiring a significant amount of time for opening and closing operations, enabling the valve to be opened and closed without human intervention, and controlling the degree of valve opening by remotely controlling an electric motor according to the turbidity value of the surrounding water quality during valve opening and closing. Generally, a water shut-off valve is a gate valve installed in underground piping that opens and closes the flow of water as the valve moves up and down by the rotation of an opening/closing rod. Typically, the structure consists of a valve body connected to a pipe buried underground, a valve provided in the valve body to open and close the flow of water, an opening/closing rod to raise and lower the valve, and a handle to rotate the opening/closing rod, wherein the opening/closing rod raises and lowers the valve to open and close the flow of water as the handle is rotated. In such underground piping facilities for water supply, sewage, or industrial use, shut-off valves are installed at appropriate locations to open and close the flow path, allowing the valves to be operated in the event of construction work or an accident. In addition, existing shut-off valves are operated by opening the shut-off cover of the shut-off valve on the ground and inserting an operating key or handle into the opening/closing rod. However, if the distance between the opening/closing rod of the valve body and the shut-off rod is far, it is difficult to insert the operating key or handle, which has caused difficulties in operating the shut-off valve. In addition, when operating valves buried underground for purposes such as maintenance on pipelines, they must be rotated for anywhere from tens to thousands of turns, which is inconvenient as it requires working for a long time. Furthermore, if the opening and closing of the valve causes a change in fluid flow, there is a possibility of secondary accidents, such as turbidity in the surrounding water, so they must be opened and closed slowly. Of course, portable electric valve actuators for long-term opening and closing have been developed on the market, but since this also requires the operator to operate it directly on-site, there was a problem in that it was difficult to determine the optimal working time.
