Sound and vibration phenomena of gas burner valve

Through a system of gas Burner Valves say anything stove Coupling FEM and analyze the results of the sound field, and finally can draw the following conclusions:

     a. Further demonstrates the hole jet of gas burner valve is one of the effective ways to reduce the noise from the simulation point of view.

     b. Only when the aperture diameter is about 4mm, the silencing effect of noise reduction is better. If the aperture gas burner valve is too small, the hole is easily clogged impurities in the gas, if the pore size is too large, the high frequency noise can not be filtered off, reach the silencing effect of noise reduction.

     c. The results show that the calculation process and, Gas Valve is a more practical finite element software, its user interface is good, before and after treatment powerful computing and high precision, is to solve the acoustic field distribution of effective processing of finite element software.
