Embodiment Construction
[0029] With regard to the structural composition of the present invention, and the effects and advantages that can be produced, with the accompanying drawings, a detailed description of the preferred embodiments of the present invention is given below.
[0030] Please refer to figure 1 , The smart valve of the present invention includes:
[0031] A valve element 10 is connected to a pipeline 60, and can perform flow control of the fluid in the pipeline 60; the valve element 10 includes a valve plate 12 for controlling the flow through the valve element 10 For the flow of fluid, 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, which is a power output device such as an electric or pneumatic device. 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...

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, most of them are provided with a valve 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 set a flow meter at a specific position in the pipeline, and to control the size of the switch in the valve body in an electronic way to control the flow in the tube. Only in this way, most of the information is sent to the control room to be monitored by a dedicated person, and the monitor sends the required flow rate to the valve body controller in the form of a control signal to control the flow rate in the tube. However, most of the above-mentioned monitoring methods need to rely on the monitor's own judgment on the information to s...
