Burner Valve Performance Testing

1. burner Valve Performance Testing

1.1 Gas Burner Safety Valve of a standard volume manufacturing, should be entrusted to an authoritative organization for testing the performance of the following: ① burner Valve pressure in the working conditions of the opening and closing torque; ② pressure in the working conditions, to ensure the burner Valve is closed tight opening and closing times in a row; ③ burner Valve flow resistance coefficient detected at aqueduct conditions.

1.2 burner Valve at the factory should be carried out to detect the following: ① burner Valve in the open position, the Burner Valves shall be subjected to internal pressure is detected twice the value of the working pressure burner Valve; ② the closed condition of the burner Valve, both sides were to withstand 1.1 times the value of the working pressure burner Valve no leakage; but the metal sealing butterfly burner Valve, leakage is no greater than the relevant requirements.

2. burner Valves and external corrosion

2.1 body (including the variable speed transmission box) inside and outside, first, blasting sand blasting, seek non-toxic epoxy powder electrostatic spraying, the thickness of 0.3mm or more. Large electrostatic spraying toxic epoxy resin burner Valve difficulty should brush, spray similar to non-toxic epoxy paint.

2.2 as well as all parts of the body inside the burner Valve plate calls for a comprehensive anti-corrosion, on the one hand immersed in water will not rust, does not produce galvanic corrosion between the two metals; two aspects of a smooth surface to reduce drag through the water.

2.3 Range Dual Safety Valves body paint anti-corrosion epoxy resin or health requirements, should detect the appropriate authority of the agency report. Chemical and physical properties should meet the relevant requirements.
