| titleOfInvention | The manufacturing method of high-efficient low-noise piston compressor valve plate |
| abstract | The invention discloses a kind of manufacturing method of high-efficient low-noise piston compressor valve plate, the compressor includes cylinder head, wherein valve plate is equipped with crescent air entry, and crescent air entry is the through-hole of crescent.Valve plate is powder metallurgy part；The technical process of valve plate manufacturing method are as follows: mixed powder；With mold compression moulding；High temperature sintering；Shaping；It examines；Steam treatment.By adopting the above technical scheme, the pressure loss reduces, and compressor Energy Efficiency Ratio improves；Air velocity at air inlet becomes smaller, and valve block unlatching slows down, and valve block displacement becomes smaller；Meanwhile lift of valve plate reduces, and reduces valve block to limit plate and valve seating impact, valve block noise is reduced from source；In addition, the displacement of valve block reduces, the stress of valve block waist reduces, and valve block severe stress region area reduces therewith, and valve block reliability improves；Energy Efficiency Ratio is improved, pneumatic noise is reduced and improves the reliability of compressor. |
