Description
Technical field
The utility model relates to a kind of pressurized air high pressure and turns the low voltage control device.
Background technique
High pressure and the low-pressure compressed air system of factory are all separate operations at present.Several High Pressure Air Compressors form a set of high pressure air system, and several low pressure air compressors form a set of low-pressure compressed air system.High-pressure system or low service system are due to the narrow limitation of installed power configuration when operation, and compressed-air actuated air demand may be mated fully with actual gas consumption hardly, is all generally that air demand is greater than gas consumption.Stable for keeping system pressure, the part air compressor just there will be the phenomenon of emptying (discharging unnecessary pressurized air) or idle running (motor rotation but do not produce pressurized air).Because air compressor is powerful consumer, emptying or idle running all certainly will cause a large amount of energy to be wasted.
The model utility content
The utility model provides a kind of pressurized air high pressure to turn the low voltage control device, high-pressure air more than needed can be delivered to low service system after decompression, and the pressure stability that can keep again high-pressure system, solved the problem of compressed air system energy waste, practical, stablize, be convenient to observe and easy to operate.
In order to achieve the above object, the utility model provides a kind of pressurized air high pressure to turn the low voltage control device, this control gear is arranged between high pressure air system and low-pressure compressed air system, the cross over pipe that this control gear comprises UNICOM's high pressure air system and low-pressure compressed air system, and be successively set on pressure transducer, reduction valve and the modulating valve on connecting tube from the high pressure side to the low voltage side, also comprise the controller of circuit Bonding pressure sensor and modulating valve.
Described control gear also comprises the high pressure side cut-off valve that is arranged on high pressure air system one side.
Described control gear also comprises the low voltage side cut-off valve that is arranged on low-pressure compressed air system one side.
The advantage that the utility model compared with prior art has or good effect:
1, realized the intercommunication of different pressures system: Previous System is each self-operating, uncorrelated mutually.
2, simple in structure, easy to implement: the equipment of high and low pressure system does not need to do any change, only need to increase by one between 2 systems and want cross over pipe and part control gear.
3, control fully automatically, reliability is high: because device has adopted programmable controller, in its running without any need for artificial interference, when system occurs when abnormal, the contact between can 2 systems of automatic or manual cut-out.
4, reduce system energy consumption: this device can reduce or stop emptying and the idle running phenomenon of air compressor, has reduced in fact the start power of air compressor, and energy-saving effect is very obvious.
5, this device not only can be used for compressed air system, and for the gas of other kind, the decompression intercommunication between system is also applicable.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Following according to Fig. 1, illustrate preferred embodiment of the present utility model.
As shown in Figure 1, the utility model provides a kind of pressurized air high pressure to turn the low voltage control device, this control gear is arranged between high pressure air system 1 and low-pressure compressed air system 2, the cross over pipe 101 that this control gear comprises UNICOM's high pressure air system 1 and low-pressure compressed air system 2, and be successively set on the high pressure side cut-off valve 102 on connecting tube 101 from the high pressure side to the low voltage side, pressure transducer 103, reduction valve 105, modulating valve 106 and low voltage side cut-off valve 107, the controller 105(that also comprises circuit Bonding pressure sensor 103 and modulating valve 106 adopts the PID adjuster, model is Hong Run: NHR1300).
Be positioned on high-tension side pressure transducer 103 and constantly detect on high-tension side pressure, and send pressure signal to controller 105, when the pressure of high pressure air system 1, during higher than supply gas pressure, controller 105 sends signal to modulating valve 106, makes its unlatching; The Cha Zhi ⊿ P of supply gas pressure and setting pressure has determined that the open degree ⊿ P of modulating valve 106 is larger, the open degree of modulating valve 106 is larger, the amount that high pressure turns low pressure is also more, otherwise less , is when ⊿ P≤0, modulating valve 106 cuts out fully, high pressure turns low pressure and stops , as ⊿ P > 0 the time, high pressure air is delivered to low-pressure compressed air system 2 after reduction valve 105 decompressions.
When appearance of abnormal pressure fluctuates, controller 105 regulating and controlling valves 106 turn-off rapidly, the impact of avoiding abnormal conditions to produce high and low pressure system.
In addition, also can cut off the low pressure cut-off valve 107 that is positioned on high-tension side high-pressure shut-off 102 and is positioned at low voltage side by being positioned at manual mode, the contact between cutoff high compressed air system 1 and low-pressure compressed air system 2, accomplish safe operation at any time.
The utility model can high-pressure system is more than needed amount automatically go to low service system, do not need human intervention fully, stability is high, on the not impact fully of the normal air feed of high-pressure system.
After the pressurized air high pressure that uses the utility model to provide turns the low voltage control device, when high pressure air in large supply during in demand, no longer emptying of pressurized air more than needed, air compressor is no longer idle running also, the start power of low pressure air compressor also may reduce simultaneously, make to mate better between compressed-air actuated supply and requirement, energy-saving effect is very obvious.
Although content of the present utility model has been done detailed introduction by above preferred embodiment, will be appreciated that above-mentioned description should not be considered to restriction of the present utility model.After those skilled in the art have read foregoing, for multiple modification of the present utility model with to substitute will be all apparent.Therefore, protection domain of the present utility model should be limited to the appended claims.
