Embodiment Construction
[0029] With regard to the structure and composition of the present invention, as well as the functions and advantages that can be produced, the preferred embodiments of the present invention will be described in detail as follows in conjunction with the accompanying drawings.
[0030] Please refer to figure 1 , the intelligent valve with automatic detection and repair function of the present invention includes:
[0031] A valve piece 10 is connected to a pipeline 60, and can control the flow of the fluid in the pipeline 60; Fluid flow, the valve plate 12 is connected to a valve switch 14 on the valve member 10, and the valve switch 14 is connected to a valve driver 16, and the valve driver 16 is a power output device such as an electric or pneumatic device. Wherein the electric valve driver 16 can be driven by a solenoid valve or a motor. Therefore, the valve switch 14 can control the opening and closing state of the valve plate 12 in a near-end fully automatic or remote sem...

An intelligent valve with automatic detection and repairing functions comprises a valve part connected with a pipeline, a field controller, a remote control end and a failure removal unit. The valve part comprises a valve block; the valve block is connected with a valve switch; the valve switch is connected with a valve driver; a position sensor is arranged on the valve part. The field controller is connected with the valve driver and the position sensor and is provided with a logic processing unit and a signal comparison unit; a logical judgment bank is built in the logic processing unit; the signal comparison unit is provided with a position signal data bank; the position signal data bank sequentially records position signals and signal time according to the starting sequence of the valve driver and stores the position signals and the signal time into a position and time track. A standard track is built in the signal comparison unit. According to the failure removal unit, the field controller can be commanded to operate the valve part to remove failures according to accidents or return a report to far field personnel through the remote control end so as to achieve manual judgment and processing. The valve failures can be automatically detected and repaired.
Description
technical field [0001] The invention relates to a valve body control and monitoring system, in particular to an intelligent valve with automatic detection and repair functions. Background technique [0002] In today's society, in many places where fluid pipelines are used, a valve is provided at a specific position to control the flow of fluid in the pipeline. [0003] Especially for industrial use, most of the flow control is to install a flowmeter at a specific position in the pipeline, and electronically control the size of the switch in the valve body to control the flow in the pipeline. It’s just that in this way, most of the information is sent to the control room for monitoring by a special person, and the monitoring person then sends the required flow rate to the valve body controller in the form of a control signal to control the flow rate in the pipe. However, most of the above-mentioned monitoring methods need to rely on the judgment of the monitor to send out re...
