Description
Technical field
The invention belongs to compressed air Decompression Controlling field, and in particular to a kind of remote controlled compressed air air relief valve.
Background technology
Compressed air air relief valve is compressed air field general part, Common parts, and it can be by pressure higher before valve to required stress level.When in use by manual adjustment initial tension of spring, the pressure after air relief valve is balanced each other general air relief valve with spring force, so as to stablize within the specific limits.This air relief valve has certain limitation, and its setting pressure can not often adjust the occasion of supply gas pressure by remotely modifying, inapplicable Jing.
To make supply gas pressure adjustable, there is technology to use the direct controlling opening of valve of motor, by the resistance regulation crushing of valve.This method is especially high to the corresponding requirement of real-time of motor, when gas consumption changes, is steady pressure, and motor must frequently adjust, cause output pressure, flowed fluctuation very big, easily shine into injury to pipe network below and gas equipment.
It is an object of the present invention to provide one kind can quickly, stable pressure regulating equipment, can real-time regulation output pressure automatically, automation equipment, remote adjustment, remote detection output pressure can be accessed.
The content of the invention
The invention provides a kind of intelligent electric-controlled compressed air air relief valve, by detecting decompression valve outlet pressure, controls the operation of motor, adjusts initial tension of spring, so as to stability contorting output pressure.
Present invention solves the technical problem that the technical scheme for being adopted is：Air relief valve is mainly by main valve body（1）, motor（2）, controller（3）Composition.Pressure transducer（3-2）Installed in main valve body（1）Exhaust chamber（1-2）On.Motor（2）Output shaft and screw rod（1-8）Connection.Motor（2）Output shaft can drive screw rod when rotating（1-8）Rotation, drive nut（1-9）Shift up and down, nut（1-9）With diaphragm（1-4）Pressuring spring（1-7）Deform upon.Nut（1-9）With long arm configuration, upper limit position switch can be touched respectively in two extreme positions of motion（3-3）And lower position switch（3-4）.
Controller（3）By host CPU（3-1）, pressure transmitter（3-2）, upper limit position switch（3-3）, lower position switch（3-4）, motor control drive（3-5）, display module（3-6）, pressure setting module（3-7）, remote input output module（3-8）, remote communication module（3-9）Composition.
When intelligent electric-controlled compressed air air relief valve runs, pressure transducer is detected（3-1）That is air relief valve output pressure, and be compared with setting pressure, when gap is more than certain threshold value, motor（2）Rotate to corresponding direction.Motor（2）By adjusting nut after rotation（1-9）Position, so as to change spring（1-7）Pretightning force, spring（1-7）Pretightning force and air relief valve output pressure out-of-balance condition, valve element（1-3）Control decompression valve opening changes, so as to affect air relief valve output pressure, when air relief valve output pressure is less than certain limit with setting pressure, motor（2）Stop the rotation, air relief valve output pressure reaches new balance with initial tension of spring, and stable within setting pressure limit.
When setting hypertonia or too low, motor（2）Spring may significantly be adjusted（1-7）Pretightning force, it is most likely that beyond screw rod（1-8）, there is mechanical breakdown or motor in range of accommodation（2）Stall, by arranging upper limit position switch（3-3）And lower position switch（3-4）Motor can be ensured（2）Adjust in safety range, work as motor（2）Be adjusted to extreme position can not still reach setting pressure when, controller（3）Send fault alarm.
Controller（3）Remote control signal can be received, real-time regulation is carried out to output pressure.Meanwhile, this air relief valve has communication interface, goes for other intelligent control equipments.
This intelligent electric-controlled compressed air air relief valve is typically characterised by having double feedback control：The first is the feedback control between spring force and exhaust chamber's pressure, and the feedback control is rapid, stable, when admission pressure fluctuates or fluctuated with throughput, can export stable pressure at expulsion by feedback control；Second is by pressure transducer（3-2）Detection, carry out motor（2）The feedback control of regulation, the feedback control accuracy are high, especially carry out feedback regulation when setting pressure changes.
The invention has the advantages that：
1、
It is safe and reliable, air relief valve pressure at expulsion will not be caused significantly to change because of admission pressure fluctuation, flowed fluctuation.
2nd, adjust rapid, spring structure is adjusted rapidly and stable valve element when flow changes.
3rd, can remote adjustment control, it is possible to remote detection pressure at expulsion, it is adaptable to need Jing often to adjust on the intelligent control equipment of pressure.
4th, double feedback controling modes can be greatly reduced motor（2）The possibility of operation, reduces energy consumption, greatly prolongs the service life of air relief valve.
