The explosion-proof valve comprises a valve body, wherein the valve body is made from a high-strength corrosion-resistant alloy; the high-strength corrosion-resistant alloy is an copper-tin alloy; the copper-tin alloy comprises the following chemical elements in percentage by mass: 4%-9% of tin, 2%-6% of zirconium, 1%-4% of molybdenum, 0.5%-2.5% of tungsten, 0.2%-0.8% of niobium, 0.1%-0.5% of nickel, 0.3%-0.9% of chromium, 0.06%-0.09% of titanium, and copper and inevitable impurities in balancing amount; and the inner wall of the copper-tin alloy valve body is coated with a nano corrosion-resistant film. Through the mode, the explosion-proof valve has favorable chemical corrosion resistance, high safety and a long service life.
Description
Technical field
The present invention relates to explosion-proof valve field, particularly relate to a kind of gas pipeline explosion-proof valve.
Background technique
Solenoid valve relies on electromagnetic coil to produce electromagnetic force to drive the fluid control elements of the open and close of valve, is one of final controlling element commonly used in pipeline control procedure.Solenoid valve is divided into by principle: direct-acting type, step direct-acting type, leading type three major types; Be divided into by structure: diaphragm electromagnetic valve and piston electromagnetic valve two class.
Gas pipeline explosion-proof valve is arranged on gas pipeline, with gas alarm equipment common operational, when occurring cutting off in time when leaking, the generation avoided accident.Owing to there is corrosive impurity containing multiple in coke-stove gas gas, in use, corrosion to a certain degree can be caused to valve inwall on gas pipe line and pipeline.
Existing gas pipeline valve body of anti-explosion valve generally adopts cast iron or steel, because the complicated component of the combustion gas such as coal gas is various, includes plurality of impurities, and valve interior wall is easy to be corroded, and will cause leaking time serious.
