Description
Technical field
The utility model relates to a kind of automatic pressure control device, the automatically controlled automatic regulating system of a kind of specifically air compressor.
Background technique
Air compressor is under power plant drive, make the two stage compression of air through the I and II cylinder after, reach working pressure, enter gas holder through the secondary outlet pipe, become aerodynamic.Gas pressure in the gas holder is by the regulation and control of automatic regulation system for pressure to the compressor operation state, makes the gas pressure in the gas holder remain on rating value or setting value.Existing air compressor automatic regulating system includes modulating valve, easing valve and connecting pipeline etc., promptly connects easing valve on the intakeport pipeline of air compressor, and the secondary exhaust elbow of air compressor connects a control valve, has gas circuit to be connected between control valve and the easing valve.When the gas pressure in the gas holder reaches specified or during setting value, the pressurized air of being made by air compressor backs down modulating valve through the secondary exhaust elbow, enter easing valve along being communicated with gas circuit, the spool of easing valve is depressed, close the air compressor intakeport, make the air compressor running no load, the pressure in the gas holder no longer rises.Along with the work of gas equipment, jar internal air pressure descends.After the gas pressure in the gas holder was reduced to certain value, modulating valve turn-offed voluntarily, was communicated with gas circuit between closure and the easing valve, made pressurized air can not enter easing valve.This moment, the spool of easing valve was upspring, and the air compressor intakeport is opened, and air compressor recovers load running again, continued to carry in gas holder pressurized air.
This automatic regulating system, because the setting of force value is to rely on the regulation and control to the nut in the modulating valve, jackscrew and spring to realize, therefore be a kind of mechanical automatic regulating system, have following deficiency: the one, the pressure upper and lower limit is difficult for changing, and narrow limitation is bigger; The 2nd, vibrations easily make the nut loosening in the modulating valve greatly during owing to air compressor work, cause the force value distortion of setting, influence proper functioning; The 3rd, the pressure adjustment must be just can carry out under open state, owing to be a kind of dynamic adjustment, causes the accuracy of regulating inconvenience and design of pressure not high.
The model utility content
The purpose of this utility model just provide a kind of easy to adjust, accuracy good, the automatically controlled automatic regulating system of distortionless air compressor, to overcome the deficiency that original regulating system exists, satisfies air compressor user's use needs.
The utility model is achieved in that the automatically controlled automatic regulating system of air compressor is to connect easing valve on the intakeport pipeline of air compressor, the secondary exhaust elbow of air compressor connects control valve, there is gas circuit to be connected between control valve and the easing valve, institute's improvements are that the mechanical type control valve is changed into solenoid valve, and solenoid valve control circuit is electrically connected with the pressure gauge with electric contact that can be contained on the gas holder.
Design key of the present utility model, the one, replaced original mechanical type modulating valve with automatically controlled solenoid valve, the 2nd, with the set parts of pressure gauge with electric contact, and solenoid valve is controlled automatically with the solenoid valve control circuit that is controlled by pressure gauge with electric contact as Pressure testing and pressure upper limit value and lower limit value.Therefore, the pressure control of this automatically controlled automatic regulating system is accurate, the setting of pressure upper limit value and lower limit value and adjust intuitively, convenient, and the pressure adjustment restriction that not whether started shooting by air compressor is used very convenient.
