An object of the utility model is to solve current foretell problem, provide a long service life's reed valve.
For the purpose of realizing above, the technical scheme of the utility model is a long service life's reed valve, characterized by, including the disk seat body, disk seat body top set up the limiting plate, last limiting plate can dismantle with the disk seat body and be connected, last limiting plate and disk seat body between set up the last reed of being made by reed fiber material, last reed and disk seat body and last limiting plate all laminate, last reed and disk seat body can dismantle with the disk seat body and be connected. The valve seat body is fixedly connected with the air inlet end of an engine crankcase, the upper reed is opened by negative pressure when the piston is compressed after the engine is started, mixed air enters the engine crankcase from the outside and enters the combustion chamber through the air inlet to participate in combustion, the maximum height of the opened reed is limited by the upper limiting plate to determine the volume of the entered mixed air, the piston moves downwards to compress air in the crankcase when the piston does work in the combustion process to close the upper reed, and the mixed air is prevented from entering the crankcase.
Optionally, valve seat body below set up down the limiting plate, limiting plate and valve seat body can dismantle and be connected down, lower limiting plate and valve seat body between set up the lower reed of making by reed fiber material, lower reed and valve seat body and lower limiting plate all laminate, lower reed and valve seat body can dismantle with the valve seat body and be connected. In the same way, the working principle of the lower spring leaf and the lower limiting plate is the same as that of the upper spring leaf and the upper limiting plate.
Optionally, the valve seat body is provided with a rubber pad, and the rubber pad is fixedly connected with the valve seat body. The rubber pad guarantees the sealed effect of reed and valve seat body, and the control does not let the mist get into in the bent axle case.
Optionally, the upper limiting plate and the lower limiting plate are stepped. The shape is step-shaped, and the opening height of the reed is limited at the position of the high plate so as to control the maximum entering amount of the mixed gas.
Optionally, the upper limiting plate and the lower limiting plate are both fixedly connected with the valve seat body through reed fixing screws. The reed fixing screw can facilitate the installation and the disassembly of the upper and the lower limiting plates, the upper and the lower reeds and the valve seat body.
The utility model discloses following beneficial effect has: the valve seat body is fixedly connected with the air inlet end of an engine crankcase, the upper reed is opened by negative pressure when the piston is compressed after the engine is started, mixed air enters the engine crankcase from the outside and enters the combustion chamber through the air inlet to participate in combustion, the maximum height of the opened reed is limited by the upper limiting plate to determine the volume of the entered mixed air, the piston moves downwards to compress air in the crankcase when the piston does work in the combustion process to close the upper reed, and the mixed air is prevented from entering the crankcase.
