Embodiment
Explain below with reference to Figure of description intelligent flow measurement and control instrument of the present utility model being done.
Intelligent flow measurement and control instrument of the present utility model, its structure comprises flow converter 4, flow control valve 6, intelligent actuator 8, instrument 2, described flow converter 4 and flow control valve 6 interconnect, measured medium enters by the entrance point 5 of flow converter 4, endpiece 7 at flow valve 6 flows out, the rate-of flow that flow converter 4 will be flowed through wherein converts the flow electric signal to, the single-chip microcomputer that is transferred in the instrument 2 by shaping circuit and amplifying circuit is handled then, show flow information by the light-emitting diode display in the instrument 21 at last, single-chip microcomputer comes 6 actions of Control Flow variable valve by intelligent actuator 8 again in addition.
Described intelligent actuator 8 is received the signal of single-chip microcomputer, comes 6 work of Control Flow variable valve by master control borad, relay, motor, mechanical speed change mechanism.
Also be provided with signal output interface 9 and daily flow search button 10 on the described instrument 2.
Can also add the flow set button between the master control borad in described single-chip microcomputer and the intelligent actuator 8; the relay that has the switch valve key connects power supply; also by the master control borad of transformer connection, described motor has overheated overload protection arrangement and stop to power supply simultaneously.
Also be provided with hand crank 3 in the mechanical speed change mechanism in the described intelligent actuator 8.
When concrete work, because flow control valve is in the downstream of flow converter, the critical component of flow control valve is a pair of sound valve block, the main shaft of intelligent actuator has driven valve rod and has rotated with moving valve plate, change the size of runner by the relative angular displacement of sound valve block, thereby reach the purpose of regulating flow.On the flow set button of user, operate at intelligent actuator, after setting certain flow number, the circuit of instrument head will periodically compare the measured instantaneous delivery value and the flow number of this setting, if current instantaneous delivery is greater than setting value and when exceeding the scope of dead band regulation, the instrument head will send instruction and start the motor on the intelligent actuator and flow control valve is turned down, if current instantaneous delivery is less than setting value and when exceeding the scope of dead band regulation, the instruction that the instrument hair goes out can make flow control valve hold greatly.Adjusted once every 15 second time like this, during adjustment, the flow regulation pilot lamp can send light, until be instantaneous delivery near or the flow number that equals to set till.
