When the valve is fed water from the inlet end,the water enters the main valve control room through the needle valve,and flowsout of the main valve control room through the pilot valve and the ball valve to the outlet.At this time,the main valve is in a fully openor floating state.Adjust the flow control vave above the main valve,and set a certain opening degree of the main valve.Adjustingthe opening of the needle valve and adjusting the spring pressure of the pilot valve can keep the opening of the main valve at the setopening,and the pilot valve can automatically adjust when the pressure changes to keep the flow constant.
