How to choose the air valve? According to the requirements of the selected type of air relief valve and pressure regulator accuracy, and then select the maximum output flow according to the required diameter. When determining the air pressure of the valve, it should be greater than the maximum output pressure 0.1MPa. Air relief valve is generally installed in the water after the scrubber, mist eliminator or setter before, and be careful not to import and export reverse; valve should not be used when the knob to relax, so that the diaphragm is often under pressure and deformation Affect its performance. Air relief valve installation and maintenance should note the following: 1, in order to facilitate the operation and maintenance, the valve is generally mounted upright on the horizontal pipe. 2, the installation should pay attention to the flow direction of the medium in the pipeline and the direction of the arrow shown on the same break. 3, in order to prevent overpressure valve pressure, should be at least 4M at the valve outlet to install a pressure reducing valve.
