Description
Technical field
The invention belongs to pressurized air Decompression Controlling field, be specifically related to a kind of remote controlled pressurized air reduction valve.
Background technique
Pressurized air reduction valve is pressurized air field general part, Common parts, and it can by pressure higher before valve to required stress level.General reduction valve is in use by manual tune initial tension of spring, and the pressure after reduction valve and spring force balance each other, thus stablizes within the specific limits.This reduction valve has certain narrow limitation, its setting pressure not by remotely modifying, the occasion of inapplicable frequent adjustment supply gas pressure.
For making supply gas pressure adjustable, there is technology to use the direct controlling opening of valve of motor, regulating crushing by the resistance of valve.This method is high especially to the corresponding requirement of real-time of motor, when gas consumption changes, is steady pressure, and motor must frequent regulate, and causes delivery pressure, flowed fluctuation very large, to pipe network below and gas equipment easily according to becoming injury.
The object of the invention be to provide one can fast, stablize pressure regulating equipment, can real-time regulation output pressure automatically, can automation equipment be accessed, remote adjustment, remote detection delivery pressure.
Summary of the invention
The invention provides a kind of intelligent electric-controlled pressurized air reduction valve, by detecting reduction valve outlet pressure, controlling the operation of motor, adjustment initial tension of spring, thus stability contorting delivery pressure.
The technological scheme that the technical problem that the present invention solves adopts is: reduction valve is primarily of main valve body (1), motor (2), controller (3) composition.Pressure transducer (3-2) is arranged in the exhaust chamber (1-2) of main valve body (1).Motor (2) output shaft is connected with screw rod (1-8).Motor (2) output shaft can drive screw rod (1-8) to rotate when rotating, and drive nut (1-9) is shifted up and down, and deformation occurs for nut (1-9) and diaphragm (1-4) pressuring spring (1-7).Nut (1-9) has long-armed structure, can touch upper limit position switch (3-3) and lower position switch (3-4) respectively at two limit positions of motion.
Controller (3) drives (3-5), display modular (3-6), pressure setting module (3-7), remote input output module (3-8), remote communication module (3-9) to form by host CPU (3-1), pressure transmitter (3-2), upper limit position switch (3-3), lower position switch (3-4), Electric Machine Control.
When intelligent electric-controlled pressurized air reduction valve runs, detected pressures sensor (3-1) i.e. reduction valve delivery pressure, and compare with setting pressure, when gap is greater than certain threshold value, drive motor (2) rotates to corresponding direction.By adjusting nut (1-9) position after motor (2) rotates, thus change spring (1-7) pretightening force, spring (1-7) pretightening force and reduction valve delivery pressure out-of-balance condition, spool (1-3) controls reduction valve aperture and changes, thus affect reduction valve delivery pressure, when reduction valve delivery pressure and setting pressure are less than certain limit, motor (2) stops the rotation, reduction valve delivery pressure and initial tension of spring reach new balance, and are stabilized within setting pressure scope.
When setting pressure is too high or too low, motor (2) significantly may adjust spring (1-7) pretightening force, very likely exceed screw rod (1-8) regulation range, there is mechanical failure or motor (2) stall, by arranging upper limit position switch (3-3) and lower position switch (3-4) can ensure that motor (2) regulates in safety range, when motor (2) be adjusted to limit position still can not reach setting pressure time, controller (3) sends malfunction alarm.
Controller (3) can receive remote control signal, regulates in real time delivery pressure.Meanwhile, this reduction valve has communication interface, goes for other intelligent control equipments.
This intelligent electric-controlled pressurized air reduction valve characteristic feature has two feedback control: the first is the feedback control between spring force and exhaust chamber's pressure, this feedback control is rapid, stable, when suction pressure fluctuation or when fluctuating by throughput, can the exhaust pressure of stable output by feedback control; The second is the detection by pressure transducer (3-2), carries out the feedback control that motor (2) regulates, and this feedback control degree of accuracy is high, especially carries out feedback regulation when setting pressure changes.
Tool of the present invention has the following advantages:
1, safe and reliable, can not fluctuate because of suction pressure, flowed fluctuation causes reduction valve exhaust pressure significantly to change.
2, regulate rapidly, when flow changes, spring structure regulates rapidly and stablizes spool.
3, can remote adjustment control, and can remote detection exhaust pressure, be applicable to need often to regulate on the intelligent control equipment of pressure.
4, two feedback controling mode significantly can reduce the possibility that motor (2) runs, and reduces energy consumption, greatly extends the working life of reduction valve.
