此系统应用小波降噪的方法提高测试信号的质量，然后提取信号特征点，得到溢流阀动态特性的各项参数。
Applying wavelet denoise to improve the test signal, the dynamic characteristic parameters of a overflow valve were obtained by selecting characteristic point of the signal.

往复泵泵阀振动信号的常规频谱分析，由于故障特征信息往往被淹没于强大的噪声以及相邻部件的干扰而使诊断精度大打折扣。
The accuracy of traditional spectrum analysis for the diagnosis of reciprocating pump valve is not satisfied for the interference of the noise and the vibration of the adjacent parts.

对于自动喷淋中，水流指示器前宜设信号阀。 ZSDF型消防信号蝶阀：用途：ZSDF型消防信号蝶阀的顶部设有阀门启闭电信号装置，当阀门被误关闭25%（全开度的1/4）时，电信号装置便输出被误关闭的信号到消防控制中心。所以此蝶阀是消防自动喷水灭火系统的最佳配套产品。结构特点及工作原理：该蝶阀的电信号装置设计蜗杆、蜗轮驱动装置的顶部，并与阀杆直联传动，在精密全封闭的机电装置内，设有阀门开启度机械指示和进口电气元件及防锈机件。输出信号长期稳定可靠。
