Abstract
The utility model discloses a fire regulator of oil filter assembly, including base (3) the bolt that produces oil (4) are equipped with on the base, be equipped with on the bolt that should produce oil above that the portion oil outlet (5) and in draining hole (6) of its lower part, produce oil on the bolt and be equipped with pressure -regulating valve assembly (7) in its draining hole department. The utility model discloses fuel after enabling to filter gets into pressure -regulating valve assembly through the draining hole of the bolt that produces oil. When this fuel pressure reached or exceed pressure -regulating valve assembly's design pressure, pressure -regulating valve assembly work made the fuel fuel tank that flows back to it obtains fine release to use the oil head. When oil circuit pressure is less than the pressure of pressure -regulating valve assembly settlement, pressure -regulating valve assembly self -closing. Thereby eliminated the potential safety hazard of oil circuit, effectively protected engine fuel oil system.
Description
Technical field
The present invention relates to a kind of cleaner, be specifically related to a kind of fuel filter assembly.
Background technology
At present, automobile, take turns fuel filter assembly peculiar to vessel include fuel filter, reversal valve,
Pedestal, under normal operation, fuel oil is after fuel filter filters, through engine pump
Valve enters combustor.Occur abnormal when electromotor pump valve and occur to open or opening difficulty
When, combustor cannot be entered according to normal condition through the fuel oil filtered, at this moment go out
The pressure of oil circuit can not get release, arises that the situation that oil pressure is the highest, will be started
Machine fuel system parts bring the biggest potential safety hazard.
Summary of the invention
It is an object of the invention to overcome above-mentioned deficiency, and provide one to realize fuel filter and go out
The regulator of the fuel filter assembly of the oil circuit pressure release during oil.
The object of the invention realizes by the following technical solutions: the pressure regulation of fuel filter assembly
Device, including pedestal, equipped with going out oil draining bolt on described pedestal, this goes out oil draining bolt and is provided with
The oil outlet on its top and the oil leak hole in its underpart；Go out to let out on oil draining bolt and at it described
Equipped with valve module of voltage regulation at oilhole.
Described valve module of voltage regulation includes pressure regulator valve body, shell, fills on described pressure regulator valve body
Having oil return bolt, at described shell built with piston, this piston passes through return spring and stud phase
Connecing, be provided with shell oil-out on this shell and at piston, described shell, pressure regulator valve are originally
There is between body, oil return bolt the drainback passage of intercommunication.
Use after the present invention, when whole fuel path pressure or electromotor pump valve occur abnormal (as
Blocking) time, the fuel oil after filtration just enters valve module of voltage regulation by the oil leak hole going out oil draining bolt.
When this fuel pressure meets or exceeds the design pressure of valve module of voltage regulation, the work of valve module of voltage regulation
Plug makes return spring be promoted compression, and fuel oil is just led to by oil return from the shell oil-out of shell
Road, oil return bolt and be back to fuel tank well discharged so that going out oil pressure.When
During the pressure that oil circuit pressure sets less than valve module of voltage regulation, valve module of voltage regulation is automatically switched off.Thus
Eliminate the potential safety hazard of oil circuit, effectively protect engine fuel oil system.
Accompanying drawing explanation
Fig. 1 is the mounting structure schematic diagram that the present invention is applied to pressure-adjustable type fuel filter assembly.
Fig. 2 is the side view of Fig. 1.
Fig. 3 is the structural representation of the present invention.
Detailed description of the invention
Below by way of accompanying drawing, the present invention is described in further detail with embodiment.
Referring to figs. 1 through Fig. 3, the regulator of fuel filter assembly of the present invention, including pedestal
3, equipped with going out oil draining bolt 4 on described pedestal 3, this goes out oil draining bolt 4 and is provided with at an upper portion thereof
Oil outlet 5 and oil leak hole 6 in its underpart；Go out to let out on oil draining bolt 4 and at it described
Equipped with valve module of voltage regulation 7 at oilhole 6.Described valve module of voltage regulation 7 include pressure regulator valve body 8,
Shell 10, equipped with oil return bolt 9 on described pressure regulator valve body 8, in described shell 10
Equipped with piston 11, (it is outer by nut 19 with stud 13 by return spring 12 for this piston 11
It is nested) connect, on this shell 10 and at piston 11, it is provided with shell oil-out 14,
There is between described shell 10, pressure regulator valve body 8, oil return bolt 9 drainback passage of intercommunication
15.The pressure-adjustable type fuel filter assembly that the present invention is applied, also includes that fuel filter 1 (is
Left and right two pieces), reversal valve 2, reversal valve 2 is contained on pedestal 3, and pedestal 3 is then contained in combustion
On oil rectifier 1 (at its oil-out).
Wherein, in described pedestal 3, it is provided with (matching with the oil-out of fuel filter)
Fuel filter oil discharge passage 16, (matching with reversal valve) commutation mouth 17, on pedestal 3
Be additionally provided with (matching with the oil-in of fuel filter) fuel oil oil-in 18, described in go out
Oil draining bolt 4 is located above the commutation mouth 17 of this pedestal 3.Described go out oil draining bolt 4 by it
Oil outlet 5 connects with outlet line joint 20, and described oil return bolt 9 is by its spill port 21
Connect with return line joint 22.
As shown in drawings, the operation principle of the present invention is: first, fuel oil is through fuel filter
After filtration, pass sequentially through the oil-out of this fuel filter, fuel filter oil discharge passage 16,
The commutation mouth 17 that matches with reversal valve and enter out oil draining bolt, fuel oil passes through under normal circumstances
The oil outlet 5 going out oil draining bolt is entered burning by outlet line joint (engine pump valve action)
Room.By the commutation effect of reversal valve, the fuel filter work on left side or right side, when wherein
The fuel filter of the side Shi Zeneng that goes wrong changes at any time, it is achieved uninterrupted fuel feeding.
When whole oil circuit pressure or electromotor pump valve occur abnormal (such as blocking) to occur opening
The when of opening or open difficulty, the fuel oil after filtering is just by going out the oil leak hole of oil draining bolt
6 enter valve module of voltage regulation 7.When this fuel pressure meets or exceeds the design pressure of valve module of voltage regulation
During power, the piston 11 of valve module of voltage regulation moves right, and makes return spring 12 be compressed by promotion,
Fuel oil just passes through drainback passage 15, the oil return of oil return bolt 9 from the shell oil-out 14 of shell
Hole 21, return line joint and be back to fuel tank obtain well so that going out oil pressure
Release.When the pressure that oil circuit pressure sets less than valve module of voltage regulation, at the return of return spring
Under effect, to left movement, valve module of voltage regulation is automatically switched off piston.Thus reach to protect Fuel System
The purpose of system.The present invention is applied in the engine system such as automobile, steamer.
