Scope

This part of GB/T 17213 specifies the sound pressure level measurement method of the noise generated by the liquid flowing through the control valve and the method for determining the characteristics of the noise increase due to cavitation. This standard also specifies the equipment, methods and procedures required to measure airborne noise in the laboratory to determine these characteristics. Airborne noise includes noise radiated by the control valve and its attached piping arrangement, including the fixed restriction through which the test fluid (water) flows (see Note 1). The main purpose of this part of GB/T 17213 is to provide a method for determining the characteristics of noise increase due to cavitation, including methods for measuring the noise generated by hydrodynamic flow through control valves. The method of measuring the radiation noise of the control valve and the attached test pipeline can make the comparison of various measured data, which is beneficial to both the user and the manufacturer. The noise that needs to be measured includes the noise radiated by the control valve itself and the noise generated by the control valve radiated from the attached piping system. The test uses water as the test fluid, and the test data is represented by the sound pressure level of the controlled valve. The determination of the sound power level is not considered within the scope of this standard. Noise characteristics can be used for the following purposes: a) to determine the characteristic pressure ratio coefficient x_FZ of a control valve; b) to predict the noise of a control valve under specified process conditions; c) to compare the performance of different control valves; d) to develop extended work life, measures to reduce noise.
