Flash condition noise stove top burner valve

    Blocking flow through the gas burner safety valve when a flash occurs, the bubble generated downstream adjustment Gas Burner Safety Valve will produce erosion by scouring the spool surface will smooth polished appearance, this
    From the mechanism of the gas burner safety valve to flash the (PVC <PV and P2 <PV) adjustment, the flash can not be eliminated, only to find ways to reduce the harm flashing on the stove valve, thereby reducing noise. Commonly used method is the region of the material to be washed surface hardening treatment, surface hardening treatment methods include three types:
    (1) The seat and the gas brass safety valve surface spraying, can be sprayed tungsten carbide, chromium carbide  to increase the hardness and other parts subject to erosion.
    (2) the surface of the stove valve seat and valve body surfacing treatment, usually by welding to increase the hardness of erosion site.
    (3) the valve seat and valve surface nitriding treatment to improve the surface hardness and wear resistance, corrosion resistance.
    By adjusting the burner valve surface hardening treatment can improve the hardness of the stove valve, the control 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 Safety Valve 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 valve, which can effectively reduce the noise level of about 25dB.
