为消除公共场所使用蒸气加热水产生的噪声，我们依据汽-水转换、压力衰减原理潜心研究，自行设计了蒸气喷头式消音器（以下称简消音器，该消音器于1999年5月12日获国家专利，专利号为98213322．7）。为了解消音器消除公共场所蒸气加热水产生的噪声效果，我们于1997年11月～1998
In order to eliminate the noise generated by using steam to heat water in public places, based on the principle of vapor-water conversion and pressure attenuation, we devoted ourselves to the design of a steam shower head type muffler (hereinafter referred to as a muffler, which was put into operation on May 12, 1999 Won the national patent, patent number 98213322.7). In order to understand the muffler to eliminate the noise generated by steam heated water in public places, we in November 1997 to 1998
