Abstract
The invention discloses a dynamic flow on-line detecting system which comprises a signal collecting unit, a signal setting unit, a programmable logic controller (PLC) control unit, a valve controller and a dynamic flow valve, wherein an output end of the signal collecting unit is connected with an input interface of the PLC control unit, a communication interface of the PLC control unit is connected with an input interface of the signal setting unit, and an output interface of the PLC control unit is connected with the dynamic flow valve through the valve controller. According to the dynamic flow on-line detecting system, instantaneous flow in a channel is measured to meet requirements of variable flow regulation so that system disorder is reduced.
Description
Technical field
The present invention relates to a kind of dynamic flow on-line detecting system, particularly a kind of control system of dynamic flow valve.
Background technique
In the more fluid system of branch road, excessive and the phenomenon that some piping flow is too small of some piping flow often can occur, thereby not reach the requirement of design, can not satisfy use.And, in the excessive pipeline of water flow, produce easily impact noise, even cause the damage of equipment.The factor that affects water system balance is a lot, even perfect design is arranged, also is difficult to reach substantial balance.Usually after first debugging, when a system part or a plurality of parts change, original state of equilibrium is changed, cause new detuning phenomena, therefore need a kind of on-line detecting system of dynamic flow.
Summary of the invention
The object of the present invention is to provide a kind of dynamic flow online detection and control system.
The technological scheme that realizes above-mentioned purpose is: a kind of dynamic flow on-line detecting system comprises signal gathering unit, signal sets unit, PLC control unit, valve positioner and dynamic flow valve.The output terminal of described signal gathering unit links to each other with the input interface of described PLC control unit, the communication interface of described PLC control unit links to each other with the input interface of described signal sets unit, and described PLC control unit output interface links to each other with described dynamic flow valve through described valve positioner.
Above-mentioned dynamic flow on-line detecting system, wherein, described signal gathering unit comprises induction piece and flow transducer.
Above-mentioned dynamic flow on-line detecting system, wherein, described flow transducer is mounted in the flow transducer in the passage.
Above-mentioned dynamic flow on-line detecting system, wherein, described induction piece can evenly arrange a plurality of on the dynamic flow valve.
Above-mentioned dynamic flow on-line detecting system, wherein, described induction piece can evenly arrange a plurality of in passage.
During native system work, set initialize signal by described signal sets unit, described PLC control unit outputs signal to described valve positioner control and opens described dynamic flow valve, current enter from described dynamic flow valve, and the described induction piece that is arranged on the described dynamic flow valve sends actuating signal.When the described flow transducer of current process, described flow transducer produces flux signal, and this signal passed to described PLC control unit, described PLC control unit obtains current dynamic flow through internal arithmetic, adjust the described valve positioner control of output parameter, thereby control flow by the adjusting of described dynamic flow valve.
The present invention regulates needs by measuring instantaneous flow in the passage to adapt to variable-flow, can make the imbalance of system water power less.
