Numerical Simulation And Optimization Of Filling Valve For Filling Precision

Taking 330ml/355ml beer filling production line of cans as an object, beer filling accuracy as the goal for the amount of oxygen filling accuracy and the precision level of accuracy problems, the use of computing fluid theory of fluid dynamics analyzes, successively filled with carbon dioxide to reduce the amount of oxygen filling process and the process of beer numerical simulation and analysis, and optimization model for the analysis of results, and comparative analysis of optimal irrigation optimization items Cartridge valve structure and the control parameters, the main contents are as follows:(1) Combined with the filling valve structure and production line application of fault data, the use of 8D and bone fishbone diagram method analyses the factors which affect the filling accuracy.(2) To pop bottle filling valve as the basis, using the theory of simulation of fluid dynamics to simulate the process of carbon dioxide in sufflation replacement cans internal oxygen, carbon dioxide, get inflation trajectory driven oxygen oxygen concentration changes, pressure, velocity, turbulent kinetic energy change etc.. Variation analysis of the indicators, draw the filling direction valve structure optimization.(3) Can optimize the structure and parameters analysis in combination with the filling valve inflatable replacement, the optimization design was carried out under filling aeration quantity four aspects to the valve annular exhaust opening of the inner circle diameter, inlet valve at the bottom of the opening angle, filling rate, filling time.(4) The change of liquid level process numerical simulation of filling wine, analyzes the main causes of low level accuracy for the filling process of instability caused by large hops, blocking the exhaust port, destroyed the isobaric filling environment, which makes the liquor cannot accurate flow. And has carried on the optimized design and structural analysis for filling instability. At the end of the filling of the optimization model of valve port to carry out a static simulation, analysis of the filling valve channel stress, velocity distribution to verify the optimization design.
