Abstract
The utility model provides a vertical fuel pump assembly blind flange of components of a whole that can function independently, including fuel pump assembly flange, integrated pressure pipe quick -operation joint's filter, pressure regulator branch pipe, integrated pressure pipe quick -operation joint's the upper and lower casing of filter, with the independent injection moulding of plastics, the casing has the catching groove to detain with hanging on the filter, with under casing, filter core and filter casing on the filter, with hanging a fastener structure, assembles into the detachable filter, through " O " type sealing member, the wavy spring leaf of loop type with hang on a fastener assembles fuel pump assembly flange, the pressure regulator branch pipe is moulded plastics as an organic wholely with filter inferior valve body and function electrically conductive material. The utility model has the advantages of, through the filter housing who uses plastics, because the shaping of working of plastics design and processing is simple, the process is few, has improved processing cost and production efficiency greatly. The filter core can be torn open alone and trade when maintaining the maintenance in the filter, and the whole filter assembly that does not need to be changed.
Description
Technical field
The utility model relates to a kind of fuel oil pump assembly blind flange, particularly a kind of Split type vertical fuel oil pump assembly blind flange.
Background technique
As an important part for vehicle fuel electric-controlling injection system, the effect of fuel oil supply system is: the gasoline in cylinder required for supply burning.And fuel oil supply system comprises the parts such as fuel tank, fuel oil pump assembly, fuel oil buffer, fuel pressure regulator, fuel filter, fuel pipe, oil sprayer.The fuel pressure regulator of existing most of fuel oil supply system and filter cleaner are all be distributed in the distant position of distance fuel oil pump assembly blind flange.Existing is be integrated in the pressure regulator of metal shell by filter cleaner, then by interference fit, is compressed into by pressure regulator and be embedded with on the fuel oil pump assembly blind flange of rubber seal.But this mode has these points defect:
1. due to pressure regulator metal shell, no matter be upper shell or lower shell body, forming process is many and complicated, and cause manufacturing efficiency low, cost is high.
2. due to pressure regulator metal shell, in order to ensure sealing, can only increase laser bonding operation and by upper-lower casing welded seal jail.And laser welding apparatus costly.
3., because pressure regulator adopts permanent laser bonding operation to connect upper-lower casing, cause the fuel filter being integrated in the inside cannot change separately, unless changed by whole pressure regulator.
4., due to only by interference fit, compressed into by pressure regulator and be embedded with on the fuel oil pump assembly blind flange of rubber seal, cause pressure regulator easily to rotate, the risk of leakage of oil is larger.
Summary of the invention
In order to solve the defect of aforementioned existence, simplify vehicle fuel supply system and minimize line upper portion part and be connected with parts, eliminate on supply pipeline owing to crossing the connection of multi-part and parts and the potential leakage that causes simultaneously, a kind of Split type vertical fuel oil pump assembly blind flange is provided, comprise fuel oil pump assembly flange, the filter cleaner of integrated pressure pipe rapid pipe joint, pressure regulator arm, it is characterized in that, on the filter cleaner of integrated pressure pipe rapid pipe joint, lower shell body, with the independent molding and forming of plastics, upper filter shell has catching groove B, buckle C, " O " o-ring groove D, filter cleaner lower shell body has catching groove E, by upper filter shell, filter core and filter cleaner lower shell body, use hanging fastener structure, be assembled into dismountable filter cleaner, be assembled on fuel oil pump assembly flange by " O " type Sealing, ring-like wavy spring sheet and hanging fastener, pressure regulator arm and filter cleaner lower shell body conductive material are injected into one.
The utility model has the advantage of, by using the filter housing of plastics, because products design machine shaping is simple, operation is few, considerably improves processing cost and manufacturing efficiency.
By by filter cleaner upper-lower casing individually shaping mechanical package again, filter cleaner inner filter core, when maintaining, can change separately, and not need to change whole filter assembly.
By pressure regulator arm and filter cleaner lower shell body being done integrally and with conductive material, enormously simplify pipeline and joint thereof on the one hand, thus make product compacter and reduce may revealing of causing due to joint; In addition on the one hand due to conductive material, will easily and effectively the electrostatic in filter cleaner be removed by the electric wire received on pressure regulator valve, thus the electrostatic of accumulation is avoided causing fuel oil pump assembly damaging or forming thermal effect.
