Specific embodiment
The utility model is further described and explained below in conjunction with the accompanying drawings.
As shown in Figure 1, the utility model is applied to fuel oil prefilter, the utility model includes being vertically arranged in prefilter master
The second conduit 1 in housing 2 and the first conduit 3 positioned at 1 lower section of the second conduit, first conduit 3 are arranged including pump oil
Airway 3-1 and flowline 3-2, the upper end of the pump oil exhaust manifolds 3-1 are connected with the lower end of the second conduit 1, the pump oil
The one side of exhaust manifolds 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
One side is provided with diaphragm check valve 6 between electric pump 8, and the diaphragm check valve 6 is located at the same of the second conduit 1 with flowline 3-2
One side.Together with prefilter 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 outer diameter of pump oil exhaust manifolds 3-1 is less than the internal diameter of the second conduit 1, as a result, the second conduit 1 and pump oil exhaust manifolds 3-1 compositions
One access, flowline 3-2 form an access.
Further, the diaphragm check valve 6 is fixed on by valve seat 5 in prefilter main casing 2.
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 of the first conduit 3 and prefilter main casing 2, makes the
One conduit 3 is stably fixed on prefilter main casing 2.
When the utility model is used, it is the 8 energization work of electric pump that prefilter carries when being screwed to ON grades using firing key,
