The tail end 704 of the valve element 7 has oblique angle.The porch Dao You oblique angles of the centre bore 302 of the valve body 3.It is easy to
The installation of valve element 7 and valve body 3, while avoiding valve element 7 from scratching valve body 3 and the scuffing oil outlet 101 of valve body 3.
After detachable check valve installation, the spring 2 is in compressive state.
The oil-through hole 301 of the valve body 3 is through hole, and the quantity of the oil-through hole 301 need to be done according to the concrete size of valve body 3
Go out rational selection
The advantage that gap coordinates is exactly to be conveniently replaceable, and only valve core taking need to be replaced into new when valve element is non-serviceable
Valve element.Because using gap cooperation, when changing the parts of check valve, only need to remove circlip 4 can
So that check valve to be disassembled from oil outlet 101, so dismounting does not need too many equipment and time.
When electric oil pump works, pressure oil flows to the direction of oil outlet 101, oil-out 102 and oil outlet from oil-out 102
Separated by check valve between 101.The check valve can only could be turned on from oil-out 102 to the direction of oil outlet 101, when fuel-displaced
When mouthfuls 102 pressure oil touches check valve, the valve head 701 of check valve is by the pressure transmission of pressure oil to spring 2.Work as pressure oil
Pressure more than spring 2 elastic force when, spring 2 will be compressed, valve head 701 also towards oil outlet 101 direction move.Valve head
701 are retracted into oil outlet 101, are no longer pressed on oil-out 102.Check valve is opened, and pressure oil enters oil outlet 101, by valve body 3
Oil-through hole 301 flows out electric oil pump.
When electric oil pump quits work, valve head 701 presses in oil-out 102 again in the presence of the elastic force of spring 2 so that
Oil-out 102 and oil outlet 101 are kept apart, when external pressure oil passes through oil outlet 101 to electric oil pump internal flow, valve head
701 can more press in oil-out 102 under the pressure of outside pressure oil so that external pressure oil cannot be introduced in electric oil pump
Portion, it is ensured that electric oil pump being capable of normal work.
