Description
Technical field
This utility model is related to cleaner technical field, more particularly, to a kind of cleaner of double-valve structure.
Background technology
Cleaner is connected on the pipeline between fuel pump and throttle valve body oil-in, and effect is to filter engine fuel gas
Deleterious particle in system and moisture content, to protect oil pump nozzle, cylinder sleeve, piston ring etc., reduce abrasion, it is to avoid blocking.Cleaner
Including housing, in housing, there is the filter core assembly that filter paper is constituted, the cleaner of prior art often occurs backflow when using
Phenomenon, causes smoothing effect to reduce.
Content of the invention
In order to solve above-mentioned technical problem, a kind of cleaner of double-valve structure that this utility model provides.
The technical scheme that this utility model is taken for achieving the above object is:
A kind of cleaner of double-valve structure, this cleaner includes the housing of open top, bottom lock, described housing upper end
It is provided with cover plate, described cover plate is provided with sealing ring fixed plate, on described sealing ring fixed plate, sealing ring is fixedly installed, described
Cover plate on be provided with oil-in, be provided with non-return valve block below described oil-in, setting filter core assembly in described housing,
Check-valves are set at the upper cover plate oil-out of described filter core assembly.
As improving further, described check-valves include check valve body, and described check valve body is sealingly disposed in fuel-displaced
Mouthful, the bottom setting fuel feed hole of check valve body, described fuel feed hole arranges non-return valve seat, described non-return valve seat arranges film
Piece, the pad of diaphragm is pushed down in setting on described diaphragm, and described pad arranges spring, described spring one end and pad phase
Support, the other end is connected with valve seat by arranging fixed mount.
As improving further, described non-return valve block lateral wall is connected with acclivitous valve arm, described valve arm arm
End supports on the cover board.
This utility model structure is simple, it is easy to accomplish.Coordinated with check-valves by non-return valve block, can more efficiently prevent from back
Stream.This utility model improves the smoothing effect of fuel filter, also improves the service life of fuel filter.
