Abstract
The utility model relates to a fuel oil filter seat and a fuel oil filter with the fuel oil filter seat. The fuel oil filter seat comprises a seat body and a manual pump integrated with the seat body, wherein the manual pump comprises a piston which moves in a pump body in a sealed manner, a return spring positioned in the pump body and between the inner side of the piston and the seat body, and a gland which is propped against the top of the piston and can move in a certain range. Through using the piston type manual pump to replace a diaphragm type manual pump, the pump oil mass of the manual pump is increased, and thereby the oil pumping frequency occuring when a user replaces a new filter is reduced.
Description
Technical field
The utility model relates to a kind of have the fuel filter seat of big pump oil mass hand pump and the fuel filter that comprises this fuel filter seat.
Background technique
At present, some fuel filter seats are integrated with hand pump, so that the air in new filter cleaner of oil-fired system and the pipeline is discharged.By pushing hand pump the fuel oil in the fuel tank is filled with filter cleaner or fuel pipe by the low pressure oil circuit, no air existence in the oil circuit of oil-fired system guarantees to start normal startup of function and work when guaranteeing engine operation.
Fig. 1 shows the fuel filter seat 1 of prior art.The oil-feed side of fuel filter seat 1 has filler opening 2 and oil suction chamber 3, and the clean side of filter cleaner seat 1 has oil pocket 4, main one-way valve 5, the oil outlet 6 after the element kit (not shown) filters, and the clean side of filter cleaner also is integrated with bypass type hand pump 7.Hand pump 7 comprise hand pump fixed cover 8, hand pump enclosing cover 9, seal membrane 10, hand pump travel(l)ing rest 11 and be arranged on hand pump travel(l)ing rest 11 and fuel filter seat 1 between Returnning spring 12.Hand pump fixed cover 8 is fixed on the fuel filter seat 1; Hand pump enclosing cover 9 is spacing by hand pump fixed cover 8; Hand pump travel(l)ing rest 11 is enclosed within on the directional post 13 of fuel filter seat 1 movably; Seal membrane 10 parts are clamped between hand pump enclosing cover 9 and the hand pump travel(l)ing rest 11, and a part is clamped between hand pump fixed cover 8 and the fuel filter seat 1, thereby seal membrane 10 separates the pump chamber 14 of bypass type hand pump 7 with the external world.
When using hand pump, main one-way valve 5 is in closed condition: when against Returnning spring 12 hand pump enclosing cover 9 being pressed, hand pump travel(l)ing rest 11 moves along directional post 13, the volume of pump chamber 14 reduces, pressure raises, fuel-displaced one-way valve 15 is opened, and in line check valve 16 is closed, and the fuel oil in the pump chamber 13 enters oil outlet 6 through fuel-displaced one-way valve 15; When discharging hand pump enclosing cover 9, because hand pump fixed cover 8 is spacing, hand pump enclosing cover 9 returns back to the home position under the effect of the elastic force of Returnning spring 12, the volume of pump chamber 14 increases, pressure reduces, fuel-displaced one-way valve 15 is closed, and in line check valve 16 is opened, and this moment, fuel oil entered pump chamber 14 from oil pocket 4 by in line check valve 16.By constantly pushing hand pump 7 repeatedly, fuel oil can be sucked in fuel filter seat 1 and the whole oil-fired system, and gas inside is discharged.
When engine start, oil outlet 6 is in negative pressure oil suction state, and main one-way valve 5 is opened, and fuel-displaced one-way valve 15 and in line check valve 16 are in closed condition, the fuel oil in the oil pocket 4 pass directly that main one-way valve 5 enters oil outlet 6 and not bypass through hand pump 7.
Yet, fuel filter seat of the prior art adopts the diaphragm type hand pump, because of diaphragm compressive fitment (roll extrusion or screw tightening), the form structure almost plane of the hermetic unit of diaphragm, so the volume of air that diaphragm compresses in the hand pump pump chamber in the process that moves up and down is very little at every turn, so the each pump oil mass of hand pump is also very little.And then increase the pump oil number of times of user when more renewing filter cleaner, cause the user to complain.
