The utility model has regulating function and simultaneously has the advantage of an electromagnetic valve.
Description
Technical field
Digital pressure/flow regulating electromechanical equipment belongs to process variables controlling device field, relates in particular to a kind of flow/pressure modulating valve.
Background technique
The process variables regulating system is made up of three parts of measuring transducer, regulator and actuator usually, its equipment be electrically connected more complicated.It is little in use to exist regulation range as the electronic or pneumatic control valve of actuator, easily leaks, often stifled card, heavy, heaviness, wide in variety, type selecting complicated problems.Adopt the solenoid valve volume of electromagnetic drive mechanism little, in light weight, action is fast, and good seal performance is used but make cut-off valve usually, can not carry out regulatory function.
The model utility content
The purpose of this utility model is to provide the digital pressure/flow regulating electromechanical equipment that has regulatory function and have the solenoid valve advantage concurrently.
Of the present utility model being characterised in that: it is the electromechanical digital-code type, and it contains: have the valve body of n fluid passage in the same housing, be positioned at each passage separately respectively by 1,2,4,8 ..., 2
N-1Weighted code distribute its area of passage, thereby make total area of passage of above-mentioned valve body have 2
nPlant the digital throttle element that changes, control n electromagnetic drive mechanism of n passage switching respectively, be used to measure the process variables measuring transducer of general passage internal pressure/flow and the PC programmable controller that links to each other with electromagnetic drive mechanism with above-mentioned each sensor.Described digital throttle element be n center separately have 1 passage and with housing with being threaded, the area of passage of its passage presses 1,2,4,8 respectively separately ..., 2
N-1The bolt type throttling element that distributes of weighted code.The input end of described PC programmable controller links to each other with the flow or the pressure signal output terminal of process variables measuring transducer, and output terminal output according to the difference of flow or pressure signal and respective settings value to determine binary system open and-shut mode signal that a said n passage is required and to link to each other with the input end of each electromagnetic drive mechanism.Described process variables measuring transducer is any in electron pressure table and the electronic current value.Described PC device sequence controller able to programme is any in microcontroller MCU, PC microcomputer and the dsp processor.
Use proof: it has reached intended purposes.
