Further, wear-resistant strip is embedded between piston and valve interior wall.
Further, it is embedded with bearing between guide cover and the first valve rod.
Further, the periphery of the second valve rod is provided with step, and shell fragment is embedded between step and top cover.
The utility model has the beneficial effect that：The utility model sets second spring between the first valve rod and the second valve rod,
Valve rod that can more smoothly in application valve body by guide cover, caused by effectively preventing that air pressure is excessive and causing compressing to valve rod
Air pressure is revealed at valve rod skewed wear or air inlet, extends the service life of intake valve.The utility model enters from air inlet
Gas, air pressure are more than the elastic force of second spring, and top cover promotes the second valve rod to move down, and gas enters in valve pocket, when air inflow is excessive,
From control gas port air inlet, air pressure is more than the elastic force sum of the first spring and second spring, and piston promotes the first valve rod to move up, passed through
The restoring force of second spring, the second valve rod is set to drive top cover to move up, so as to ensure that air inlet enters the air inflow of valve pocket.This practicality
New structure advantages of simple, air inflow can be ensured, effectively prevent valve rod from damaging, extend the service life of intake valve.
