Cavitation burner valve noise control

By adjusting the Burner Valve surface hardening treatment can improve the hardness of the control burner valve, the control burner valve to enhance the ability of anti-flash "erosion", the corresponding noise will be reduced 5 ~ 10dB. To further reduce noise, can be used with the methods used are: ① improve the pipe wall thickness or adding sound insulation layer in the pipe wall. Regulating burner valve the same diameter, which each additional level of pipe wall thickness, the measured value of the noise can be reduced by about 2dB; ② pipe plus sound-insulating layer to reduce the substance of pipe wall thickness also increases a measure of noise transmitted to the environment; ③ the regulating Gas Top Burner Valve after the installation of the online muffler, online muffler can absorb some of the sound energy, and after the formation of back pressure burner valve, which can effectively reduce the noise level of about 25dB.

    Blocking flow flows through the burner valve when cavitation bubbles generated in the contact portion of the burner valve rupture, collapse of bubble energy will be released slowly tearing the material, and the parts in contact with the control burner valve leaving a rough surface similar to the slag . This process will produce noise emitted as gravel stream crossing the Stove Top Burner Valve.

    Cavitation There are two ways to control: the first is to completely prevent the occurrence of cavitation; the second is not to prevent the occurrence of cavitation, but reduce its harm.
