Dual blade superhard relatively common seal gas safety burner valve seal gas safety burner valve, Aluminum safety gas valve is suitable for high temperature, high pressure, high erosion and corrosion and other working conditions, the following technical difficulties in the design and manufacturing process.
(1) Sealing pressure seal in the design of high pressure than when you should be appropriate to the requirements of high dimensional chain between the parts and improve the surface roughness.
(2) the sphere surface with high hardness, high hardness and self-cleaning function of particles of various operating conditions, the gas safety burner valve opening of the process Gas Grill Control Valve will be particles adhere to the surface of a sphere, the sphere surface hardness requirements of the gas safety burner valve is closed when the state is higher than the hardness of the particles conditions , but also to "self-cleaning" function, otherwise damage the surface of the sphere, it will affect the sealing performance of the gas safety burner valve between the seat and the ball.
(3) casting and forging more gas brass safety valve difficult to use a temperature higher than 600 ℃, castings and forgings prone to cracks, casting and forging process very demanding.
(4) sealing surfaces are processed with a hard ball superhard material or surface hardening treatment, universal tool can not be processed, which can be processed even if the machining accuracy can not meet the requirements, but also requires processing apparatus has sufficient strength, and therefore to select the appropriate tool is very important.
