Description

Intelligent controller for valve

Technical Field

The utility model relates to the technical field of valves, in particular to an intelligent controller for a valve.

Background

Valves are mechanical devices that control the flow, direction, pressure, temperature, etc. of a flowing fluid medium, and are essential components in a piping system. Valve tubing, like pumps in technology, is often discussed as a separate category. The valve can be operated manually or by a hand wheel, a handle or a pedal, and the pressure, the temperature and the flow rate of the fluid medium can be changed by control. The valve may operate continuously or repeatedly on these changes, such as a safety valve installed in a hot water system or a steam boiler. In more complex control systems, automatic control valves are employed as required by external inputs (i.e., to adjust the changing set point of the flow through the pipe). The automatic control valve does not need manual operation according to the input and the setting of the automatic control valve, so that the valve accurately controls various requirements of a fluid medium, but if the existing valve controller is based on a wired mode, the on-site wiring construction is required, time and labor are wasted, and the operation and the maintenance after delivery are also troublesome; the intelligent controller based on the local wireless network has the advantages that the wireless transmission distance is limited, the equipment state data cannot be uploaded to the server when the intelligent controller is used, the intelligent controller needs to be networked with gateway equipment to upload the data after the intelligent controller is used, the real-time performance is poor, the state of a valve cannot be accurately known, the use condition of the valve cannot be monitored in real time, and therefore, the intelligent valve controller is designed in actual production and life.
