A highly precise compressed air intelligent pressure regulator

Abstract

The invention discloses an intelligent pressure regulating device for compressed air with high precision. Through the joint action of the first pressure relief valve, the second pressure relief valve, the third pressure relief valve and the fourth pressure relief valve, the The pressure in the main buffer pressure compensation tank and the auxiliary buffer pressure compensation tank is always greater than the pressure in the terminal pressure tank, and then the main buffer pressure compensation tank and the auxiliary buffer pressure compensation tank will automatically compensate and charge a certain pressure airflow into the terminal pressure tank, so as to make the The pressure in the terminal pressure tank is as low as possible to reduce the error effect on the output pressure caused by the unstable operation of the compressor, and ensure the accuracy of the pressure output. The connection between the terminal pressure tank and the tee is equipped with a flow rate control The connector assembly, the flow rate control connector assembly can fine-tune the air flow rate according to the intake pressure, and the greater the intake pressure, the greater the air flow rate controlled by the flow rate control connector assembly, ensuring the accuracy of pressure compensation.

Description

technical field [0001] The invention specifically relates to the technical field of sprayers, in particular to a high-precision compressed air intelligent pressure regulating device. Background technique [0002] For some constructions such as painting, spraying, and glue spraying, the compressor is generally used to spray the slurry evenly and disperse, so as to obtain the sprayed film with the required precision thickness. In order to make the thickness of the obtained spray film uniform, it is necessary to keep the airflow and pressure supplied by the compressed air in a uniform and constant state, and the more accurate the pressure, the better the uniformity. However, for the compressor , when the compressor is running, the air outlet of the compressor fluctuates to a certain extent due to changes in voltage and external environment. This fluctuation easily causes the air outlet pressure of the compressor to change. The thickness of the feed liquid fluctuates, which in ...

In order to make the thickness of the obtained spray film uniform, it is necessary to keep the airflow and pressure supplied by the compressed air in a uniform and constant state, and the more accurate the pressure, the better the uniformity. However, for the compressor , when the compressor is running, the air outlet of the compressor fluctuates to a certain extent due to changes in voltage and external environment. This fluctuation easily causes the air outlet pressure of the compressor to change. The thickness of the feed liquid fluctuates, which in turn affects the quality and reliability of the injection

Although at present, pressure stabilizing valves are generally used to stabilize the pressure, but when the pressure is insufficient, it is difficult to guarantee such a stabilizing valve. Moreover, the pressure regulator valve is prone to damage under high pressure, which affects the service life, and once it is damaged, it will cause great damage at the moment of injection, affecting the effect and quality of injection
