The main function of the Fill valve The filling valve, also known as the filling valve, is a specially constructed poppet valve for mixing and discharging. The dispenser is generally composed of one or several pairs of inlet and drain valves. The throttle valve and the safety valve itself are also a poppet valve structure. Commonly used filling valves have two configurations: hydraulically controlled and spring-returned. Filling valves are generally installed directly on the master cylinder. Because the pipeline is high and the low-pressure liquid exchanges frequently, the pipeline is required to be as short as possible and reliable. The flow cross section of the filling valve shall be calculated as the maximum liquid consumption of the filling stroke. The filling valve is a special structure cone valve with high and low pressure mixing, liquid mixing and draining. Its functions are as follows: (1) When the extruder is filled (the main plunger is moving forward), the automatic low-pressure liquid enters the master cylinder; (2) When the high pressure liquid enters the master cylinder through the filling valve, it can automatically cut off the low pressure system; (3) When the main plunger returns, the high pressure liquid returns to the low pressure tank through the filling valve.
