Abstract
The invention relates to a device for controlling high-pressure compressed air to be converted into low-pressure compressed air. The control device is arranged between a high-pressure compressed air system and a low-pressure compressed air system; the control device comprises a communicating pipe used for communicating the high-pressure compressed air system and the low-pressure compressed air system, and a pressure sensor, a pressure reducing valve and a regulating valve which are sequentially arranged on the communicating pipe from the high-pressure side to the lower-pressure side; and the control device also comprises a controller which is connected with the pressure sensor and the regulating valve by a circuit. The device can send the surplus high-pressure air into the low-pressure system after reducing the pressure of the high-pressure air, and maintains the pressure of the high-pressure system to be stable, thus solving the problem of energy waste of the compressed air systems, and being practical, stable and convenient to observe and operate.
Description
Technical field
The present invention relates to a kind of pressurized air high pressure and change the low voltage control device.
Background technique
High pressure and the low-pressure compressed air system of factory all are separate operations at present.Several High Pressure Air Compressors are formed a cover high pressure air system, and several low pressure air compressors are formed a cover low-pressure compressed air system.Owing to the narrow limitation of installed power configuration, compressed-air actuated air demand may be mated fully with actual gas consumption hardly, generally all is that air demand is greater than gas consumption when operation for high-pressure system or low service system.In order to keep the stable of system pressure, the phenomenon of dally (motor rotation but do not produce pressurized air) emptying (discharge unnecessary pressurized air) just can appear or in the part air compressor.Because air compressor is powerful consumer, emptying or idle running all certainly will cause a large amount of energy to be wasted.
Summary of the invention
The invention provides a kind of pressurized air high pressure and change 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 high-pressure system has again solved the problem of compressed air system energy waste, and is practical, stablize, be convenient to observe and easy to operate.
In order to achieve the above object, the invention provides a kind of pressurized air high pressure and change the low voltage control device, this control gear is arranged between high pressure air system and the low-pressure compressed air system, this control gear comprises the cross over pipe of high pressure air system of UNICOM and low-pressure compressed air system, and from the high pressure side to the low voltage side, be successively set on pressure transducer, reduction valve and modulating valve on connecting tube, also comprise the controller that circuit connects pressure transducer 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 present invention compared with prior art has or good effect:
1, realized the intercommunication of different pressures system: Previous System is each self-operating, and is 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 increase by one between 2 systems and want cross over pipe and part control gear.
3, fully automatically control, the reliability height: because device has adopted programmable controller, in its running without any need for artificial interference, when system occurs when unusual, 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 the start power of air compressor in fact, 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 the system also is suitable for.
Description of drawings
Fig. 1 is structural representation of the present invention.
Embodiment
Following according to Fig. 1, specify preferred embodiment of the present invention.
As shown in Figure 1, the invention provides a kind of pressurized air high pressure and change the low voltage control device, this control gear is arranged between high pressure air system 1 and the low-pressure compressed air system 2, this control gear comprises the cross over pipe 101 of high pressure air system of UNICOM 1 and low-pressure compressed air system 2, and from the high pressure side to the low voltage side, be successively set on high pressure side cut-off valve 102 on connecting tube 101, pressure transducer 103, reduction valve 105, modulating valve 106 and low voltage side cut-off valve 107, also comprise the controller 105(employing PID adjuster that circuit connects pressure transducer 103 and modulating valve 106, 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 was higher than supply gas pressure, controller 105 sent signal for 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 more big, then the open degree of modulating valve 106 is more big, the amount that high pressure changes low pressure is also more many, on the contrary then more little ， when ⊿ P≤0, modulating valve 106 cuts out fully, high pressure changes low pressure and stops ， as ⊿ P〉0 the time, high pressure air is delivered to low-pressure compressed air system 2 after through reduction valve 105 decompressions.
When unusual fluctuations appearred in pressure, controller 105 regulating and controlling valves 106 turn-offed rapidly, the influence of avoiding abnormal conditions that high and low pressure system is produced.
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, safe operation is accomplished in the contact between cutoff high compressed air system 1 and the low-pressure compressed air system 2 at any time.
The present invention can the amount that high-pressure system is more than needed go to low service system automatically, does not need human intervention fully, and stability is high, to the normal air feed not influence fully of high-pressure system.
After using pressurized air high pressure provided by the invention to change 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 between compressed-air actuated supply and the requirement and mate better, energy-saving effect is very obvious.
Although content of the present invention has been done detailed introduction by above preferred embodiment, will be appreciated that above-mentioned description should not be considered to limitation of the present invention.After those skilled in the art have read foregoing, for multiple modification of the present invention with to substitute all will be apparent.Therefore, protection scope of the present invention should be limited to the appended claims.
