Blocking flow through the regulator Stove Top Burner Valve when a flash occurs, the bubble generated downstream adjustment spool Gas burner valve will produce erosion by scouring the spool surface will smooth polished appearance, this process with great noise generation.
From the mechanism of the Gas burner 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 control Gas burner 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 safety burner valve surface spraying, can be sprayed tungsten carbide, chromium carbide or increase the hardness and other parts subject to erosion.
(2) the surface of the Gas burner valve seat and gas Burner Valve body surfacing treatment, usually by welding increase the hardness of erosion site.
(3) the Gas burner valve seat and Gas burner valve surface nitriding treatment to improve the surface hardness and wear resistance, corrosion resistance.
