Pump oil exhaust manifolds lower part is provided with electric pump, and side is provided with diaphragm check valve between flowline and electric pump, and the diaphragm is unidirectional
Valve is located at the same side of the second conduit with flowline.
Further, the diaphragm check valve is fixed in prefilter main casing by valve seat.
Further, it is provided with gap between the fuel-displaced bottom of the tube and the electric pump.
Further, prefilter main casing is additionally provided with oil outlet, the oil outlet be located at diaphragm check valve and electric pump it
Between.
Further, it is interference fit between the first conduit and prefilter main casing.
Good effect of the present invention is as follows：
The present invention makes the gas in prefilter be discharged by low pressure oil way, fundamentally solves in use, by the structure of dual circuit
Determined vehicle operation when gas enter oil supply system produce harmful effect, ensure that the normal work of oil supply system to the full extent
Make.The present invention is compact-sized, securely and reliably.
Brief description of the drawings
Fig. 1 is the schematic cross-sectional view of the present invention：
In attached drawing, 1 second conduit, 2 prefilter main casings, 3 first conduits, 3-1 pump oils exhaust manifolds, 3-2 flowlines, 4 oil inlets
Mouth, 5 valve seats, 6 diaphragm check valves, 7 oil outlets, 8 electric pumps.
Embodiment
The present invention program is further described and explained below in conjunction with the accompanying drawings.
As shown in Figure 1, the present invention is applied to fuel oil prefilter, the present invention includes being vertically arranged in prefilter main casing 2
The second conduit 1 and the first conduit 3 positioned at the lower section of second conduit 1, first conduit 3 include pump oil exhaust manifolds 3-
1 and flowline 3-2, the upper end of the pump oil exhaust manifolds 3-1 connected with the lower end of the second conduit 1, the pump oil exhaust manifolds
The side of 3-1 and flowline 3-2 are co-walled；The pump oil exhaust manifolds 3-1 lower parts are provided with electric pump 8, flowline 3-2 and electric pump 8
Between side be provided with diaphragm check valve 6, the diaphragm check valve 6 is located at the same side of the second conduit 1 with flowline 3-2.In advance
Together with filter main casing 2 is bolted with electric pump 8.
In order to facilitate technique productions, second conduit 1 is plugged on the pump oil exhaust manifolds 3-1, in the present embodiment
The outside diameter of pump oil exhaust manifolds 3-1 is less than the internal diameter of the second conduit 1, thus, the second conduit 1 and pump oil exhaust manifolds 3-1 compositions
One path, flowline 3-2 form a path.
Further, the diaphragm check valve 6 is fixed in prefilter main casing 2 by valve seat 5.
Further, it is provided with gap between the bottom of the pump oil exhaust manifolds 3-1 and the electric pump 8 so that pre-flock
Gas and fuel oil in device can be discharged by the bottom gap of pump oil exhaust manifolds 3-1 by electric pump 8, and pasta is led to
Two conduits, 1 upper end.
Further, prefilter main casing 2 is additionally provided with oil outlet 7, and the oil outlet 7 is located at diaphragm check valve 6 and electricity
Between pump 8.
Prefilter main casing 2 is additionally provided with oil inlet 4, above valve seat 5, the side of the first conduit 3.Oil inlet 4 with
It is water collection chamber down.
In the present embodiment, oil inlet 4 is located at the same side of the first conduit 3 with oil outlet 7.
Further, it is interference fit between the pump oil exhaust manifolds 3-1 and prefilter main casing 2 of the first conduit 3, makes the
One conduit 3 is stably fixed on prefilter main casing 2.
The present invention is the 8 energization work of electric pump that prefilter carries in use, when being screwed to ON grade using firing key, electric pump 8
The negative pressure of generation closes diaphragm check valve 6, and gas in prefilter and fuel oil is led by the second conduit 1 and pump oil exhaust
Pipe 3-1 is discharged, and pasta is led to 1 upper end of the second conduit, the control module carried by electric pump 8 makes its work automatic after ten minutes
Stop.During normal vehicle operation, the negative pressure that oil transfer pump produces opens diaphragm check valve 6, the passage that fuel oil passes through flowline 3-2
