Prior art can not meet the needs of people, for making up prior art deficiency, the utility model aims to provide a kind of new screw air compressor pressure valve, use Differential Geometry and Principles of Gear Connection to devise molded lines of rotor and the complete machine structure of air screw pressure valve, reduce the advantages such as the operation energy consumption of screw air compressor.
For achieving the above object, the utility model is by the following technical solutions: a kind of new screw air compressor pressure valve, comprises hexagon socket head cap screw, pad, upper valve body, positioning rod, piston spring, guide rod, lower valve body, valve core spring, outer jump ring, O type circle, wear-resistant strip, piston, valve plate, Sealing and pressing plate; Described hexagon socket head cap screw runs through upper valve body and arranges pad between hexagon socket head cap screw and upper valve body; Described hexagon socket head cap screw one end is installed on positioning rod inside, and positioning rod surface arranges piston spring; Described positioning rod one end embeds guide rod inside and guide rod inside arranges valve core spring; Described upper valve body one end is connected with lower valve body one end and lower valve body side arranges piston; Described piston side arranges O type circle and wear-resistant strip; Described piston tip installs outer jump ring, and piston one end and lower valve body compact siro spinning technology; Described lower valve inner is positioned at the Sealing between valve plate and pressing plate, and is closely coupled to valve core spring inside by hexagon socket head cap screw between valve plate and pressing plate.
Further, described piston spring is installed on positioning rod and lower valve body surface, and piston spring is helix structure.
Further, described O type circle and wear-resistant strip are arranged between lower valve body and piston, and O type circle is positioned at wear-resistant strip side.
Further, described upper valve body is connected to positioning rod one end by hexagon socket head cap screw, and upper valve body is symmetrical about guide rod.
Further, described outer jump ring one end and guide rod compact siro spinning technology and outer jump ring side arranges piston spring.
The beneficial effects of the utility model are: its component of flypress pressure valve are few, convenient operating maintenance, dynamical balancing are good, strong adaptability and multi-phase mixed delivering, compact structure, size reduces, operational noise reduces, and reaches the time saving material, reduce manufacture cost, improve working life, increase failure-free operation.
