Abstract
The utility model discloses a pressure flow regulation device which comprises a main pipeline and a bypass pipeline. One end of the main pipeline is an inlet, and the other end of the main pipeline is an outlet. The bypass pipeline is connected to the main pipeline in parallel. The main pipeline is sequentially provided with a first hand valve, a pressure reducing valve, an automatic control valve and a second hand valve along the direction from the inlet to the outlet. The bypass pipeline is provided with a third hand valve. The bypass pipeline between the third hand valve and the outlet is provided with a pressure sensor. The pressure flow regulation device further comprises a controller. A signal of the pressure sensor is inputted into the controller, and the output end of the controller is connected with the automatic control valve. According to the pressure flow regulation device, when the pressure of a gas storage tank increases, the pressure flow regulation device throttles air and prevents pressure in a lower course from rising; and when more air is needed in the lower course, the regulation device releases adequate flow to meet requirements. Therefore, air supply pressure is guaranteed to be stable, and meanwhile the occasion that air consumption is supposed by a person is prevented.
Description
Technical field
The utility model relates to a kind of controlling device in the compressed air system, especially a kind of pressure flow controlling device.
Background technique
Compressed air system is used very extensively in industry, and the load of compressed air system is not what remain unchanged in many enterprises, and it is frequent and huge changing sometimes.This can cause the huge fluctuation of system's supply gas pressure usually; For being higher than, the minimum point that makes pressure surge produces minimum supply gas pressure; Compressed-air actuated administrative staff just must improve the operating pressure of whole compressed air system, will inevitably make the average operating pressure of system be higher than the needed optimum pressure of actual production like this, and relevant document shows that Compressor Discharge Pressure rising 0.1MPa is under same air displacement; Its power consumption will increase about 6%; And this also can cause the increase of gas equipment actual air consumption, leaks to increase the weight of etc., and energy consumption of compressor is increased.
And because each compressed air system all has the target supply gas pressure; The system air feed descends when being lower than goal pressure, and system's supply gas pressure causes equipment normally not move inadequately, in order under the bigger situation of user's gas consumption, to guarantee normal supply gas pressure; As improvement to compressed air system; Usually in system, all be provided with gas holder, gas holder can be used for air feed when system's supply gas pressure is not enough, and gas storage pressure must be kept above goal pressure.But do not have a kind of efficient pressure flow regulator in the existing technology, the air feed process that can regulate gas holder automatically is stable to guarantee air feed, has brought inconvenience to production.
Summary of the invention
The purpose of the utility model is that a kind of air feed process that can regulate gas holder automatically of designing for the deficiency that solves above-mentioned technology is to guarantee air feed pressure stable flow regulator.
The pressure flow controlling device that the utility model designed; Comprise a main line and a bypass line; Said main line one end is that import, the other end are outlet; Said bypass line is connected in parallel on the main line, and said main line upper inlet to the direction of outlet is provided with first manually operated valve, reduction valve, autocontrol valve and second manually operated valve successively; Said bypass line is provided with the 3rd manually operated valve, and the bypass line between said the 3rd manually operated valve and the outlet is provided with pressure transducer; Also comprise controller, said pressure sensor signal inputs to this controller, and the output of this controller connects said autocontrol valve.
As preferably: described autocontrol valve is made up of solenoid valve and Pneumatic butterfly valve, and said solenoid valve is arranged on the gas circuit of said Pneumatic butterfly valve and this solenoid valve is electrically connected with controller, and said Pneumatic butterfly valve is arranged on the said main line; May command is more simple effectively like this.
As preferably: said first manually operated valve, second manually operated valve and the 3rd manually operated valve all are Hand-operated butterfly valve; The Hand-operated butterfly valve manual tune is more convenient.
As preferably: also be provided with pressure gauge on the bypass line between said the 3rd manually operated valve and the outlet; Show more directly perceived like this.
The pressure flow controlling device that the utility model designed; When gas holder pressure increased, this pressure flow controlling device was carried out throttling to air and is prevented that downstream pressure from rising, when downstream need more air; This controlling device can discharge enough flows and satisfy the demand; So both guaranteed that supply gas pressure was stable, prevented the appearance of artificial hypothesis gas consumption situation again, thereby made that whole compressed air system efficient was higher, stability is better.
