What is a Proportional Valve

A proportional valve provides a change in output pressure or flow in the same ratio as the change in the input, for example if the input doubles then the output will also double.

Working principle of sliding vane compressor_Features of sliding vane compressor

Working principle of sliding vane compressor <img src="{{media url=&quot;magefan_blog/Working_principle_of_scroll_compressor_Characteristics_of_scroll_compressor.jpg&quot;}}" alt="" /> 　　 Air is sucked in through a filter and a regulating proportional valve. The regulating valve is mainly used to regulate the pressure chamber formed by the rotor and slide of the air cylinder. The rotor rotates eccentrically with respect to the cylinder, the valve plate is installed in the rotor groove, and the slider is pushed to the cylinder wall by centrifugal force.

Classification, principle and use of refrigeration compressors

Classification, principle and use of refrigeration compressors<br></br> The function of refrigeration compressor:<br></br> The refrigeration compressor is the "heart" of the refrigeration system. It absorbs the refrigerant vapor from the evaporator, increases the pressure and discharges it to the condenser, so that the refrigerant circulates in the system. Can be used in refrigeration systems and heat pump systems
