Abstract
The utility model discloses a fire pressure -regulating valve assembly of oil filter assembly, including air -vent valve body (8), shell (10) oil return bolt (9) are equipped with on the air -vent valve body be equipped with piston (11) in the shell, this piston passes through return spring (12) and double -screw bolt (13) and meets, and this double -screw bolt overlaps with nut (19) mutually, is equipped with shell oil -out (14) on this shell and in piston department, return path (15) that have the intercommunication between shell (10), air -vent valve body (8), oil return bolt (9). The utility model discloses fuel after enabling to filter gets into in air -vent valve body and the shell. When this fuel pressure reached or exceed 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 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 valve module of voltage regulation of the fuel filter assembly of the oil circuit pressure regulation during oil.
The object of the invention realizes by the following technical solutions: the pressure regulation of fuel filter assembly
Valve module, including pressure regulator valve body, shell, equipped with oil return bolt on described pressure regulator valve body,
At described shell built with piston, this piston is connected with stud by return spring, this stud with
Nut is nested, and is provided with shell oil-out, described shell, tune on this shell and at piston
There is between press the valve 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 will enter in pressure regulator valve body and shell.When this fuel oil pressure
When power meets or exceeds the design pressure of valve module of voltage regulation, impact piston makes return spring be promoted
Compression, fuel oil is just back to by drainback passage, oil return bolt from the shell oil-out of shell
Fuel tank, is well discharged so that going out oil pressure.When oil circuit pressure is less than pressure regulator valve group
Part set pressure time, piston, return spring return and make valve module of voltage regulation be automatically switched off.From
And 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.
The mounting structure schematic diagram that Fig. 3 is the present invention and pedestal, go out between oil draining bolt.
Detailed description of the invention
Below by way of accompanying drawing, the present invention is described in further detail with embodiment.
With reference to Fig. 3, the valve module of voltage regulation 7 of fuel filter assembly of the present invention, including pressure regulator valve
Body 8, shell 10, equipped with oil return bolt 9 on described pressure regulator valve body 8, outside described
Shell 10 is built with piston 11, and this piston 11 is connected with stud 13 by return spring 12,
This stud 13 is nested with nut 19, is provided with shell on this shell 10 and at piston 11
Oil-out 14, described shell 10 (its shell oil-out), pressure regulator valve body 8, oil return spiral shell
There is between bolt 9 drainback passage 15 of intercommunication.
Referring to figs. 1 through Fig. 3, the pressure-adjustable type fuel filter assembly that the present invention is applied, also wraps
Including fuel filter 1 (for left and right two pieces), reversal valve 2, pedestal 3, reversal valve 2 is contained in
On pedestal 3, pedestal 3 is then contained on fuel filter 1 (at its oil-out), at described base
Equipped with going out oil draining bolt 4 on seat 3, this goes out oil draining bolt 4 and is provided with oil outlet 5 He at an upper portion thereof
Oil leak hole 6 in its underpart；Described go out on oil draining bolt 4 and at its oil leak hole 6 equipped with
The valve module of voltage regulation 7 of fuel filter assembly.
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 in the pressure regulator valve body 8 of valve module of voltage regulation 7 of fuel filter assembly, shell 10.
When this fuel pressure meets or exceeds the design pressure of this valve module of voltage regulation, piston 11 is to the right
Motion, makes return spring 12 be compressed by promotion, and fuel oil just leads to from the shell oil-out 14 of shell
Cross drainback passage 15, the spill port 21 of oil return bolt 9, return line joint and be back to combustion
Fuel tank, is well discharged so that going out oil pressure.When oil circuit pressure is less than this pressure regulator valve group
During the pressure that part sets, under the return effect of return spring, piston is this pressure regulation to left movement
Valve module is automatically switched off.Thus reach to protect the purpose of fuel system.The present invention be applied to automobile,
In the engine systems such as steamer.
