The flow stabilizer for the electronic injection fuel pump comprises an adjusting screw, an upper cover, an adjusting spring, an upper diaphragm pressure plate, a diaphragm, an adjusting spool, a lower diaphragm pressure plate, a fixed seat, a throttling steel ball, a throttling spring, a spring pressure plate and an oil nozzle, wherein the adjusting screw is arranged at the top end of the upper cover; the adjusting spring is arranged at the bottom end of the adjusting screw; the middle part of the diaphragm is clamped between the upper diaphragm pressure plate and the lower diaphragm pressure plate; the adjusting spool passes through the upper diaphragm pressure plate, the diaphragm and the lower diaphragm pressure plate and is connected with the throttling steel ball; the fixed seat is arranged between the upper cover and the oil nozzle; the throttling spring is positioned above the spring pressure plate; and the spring pressure plate is clamped in the gap of the fixed seat and is positioned above the oil nozzle. The flow stabilizer for the electronic injection fuel pump improves the combustion ratio of automotive fuel, reduces pollution brought by discharge, saves energy and protects the natural environment.
Description
Technical field
The utility model relates to a kind of electric-spraying fuel pump, particularly a kind of electric-spraying fuel pump constant-current stabilizer.
Background technique
Present electric-spraying fuel pump is generally stablized fuel pump pressure by constant pressure valve, but constant pressure valve also can change along with the variation of flow, because the output voltage on the automobile is earthquake, when output voltage is high; The flow of fuel pump is just big, and it is also unstable to produce the flow of the fuel pump that the manufacturer of electric-spraying fuel pump produces, and it is low that the height that has has, and is difficult to control.When flow is high; The pressure of constant pressure valve is also just big more, and at this moment the fuel consumption of automobile is also just big more, and oil occurring can not perfect combustion, and the tail gas black smoke that automobile is discharged is billowing.Waste resource and also polluted physical environment.
The model utility content
The utility model technical problem to be solved provides a kind of electric-spraying fuel pump constant-current stabilizer, and it improves the rate of combustion of vehicle fuel, reduces the pollution that discharging is come, energy saving, conservation of nature environment.
For solveing the technical problem; The utility model provides a kind of electric-spraying fuel pump constant-current stabilizer; It is characterized in that it comprises regulates screw, loam cake, Regulation spring, diaphragm top board, diaphragm, regulating spool, diaphragm press table, fixed base, throttling steel ball, throttling spring, spring pressuring plate, oil nozzle, regulates the top that screw is located at loam cake; Regulation spring is in the bottom of regulating screw; The therebetween of diaphragm is between diaphragm top board and diaphragm press table, and regulating spool is connected with the throttling steel ball after passing diaphragm top board, diaphragm, diaphragm press table, and fixed base is located between loam cake and the oil nozzle; The throttling spring is positioned at the top of spring pressuring plate, and spring pressuring plate is stuck in the space of fixed base and is positioned at the top of oil nozzle.
Preferably, the two ends of said diaphragm also are clipped between loam cake and the fixed base.
The positive progressive effect of the utility model is: the utility model electric-spraying fuel pump constant-current stabilizer improves the rate of combustion of vehicle fuel, reduces pollution, energy saving and conservation of nature environment that discharging is come.
Description of drawings
Fig. 1 is the structural representation of the utility model electric-spraying fuel pump constant-current stabilizer.
Embodiment
Lift a preferred embodiment below, and combine accompanying drawing to come the clearer the utility model of intactly explaining.
As shown in Figure 1; The utility model electric-spraying fuel pump constant-current stabilizer comprises regulates screw 1, loam cake 2, Regulation spring 3, diaphragm top board 4, diaphragm 5, regulating spool 6, diaphragm press table 7, fixed base 8, throttling steel ball 9, throttling spring 10, spring pressuring plate 11, oil nozzle 12; Regulate the top that screw 1 is located at loam cake 2; Regulation spring 3 is in the bottom of regulating screw 1, and the therebetween of diaphragm 5 is between diaphragm top board 4 and diaphragm press table 7, and regulating spool 6 is connected with throttling steel ball 9 after passing diaphragm top board 4, diaphragm 5, diaphragm press table 7; The two ends of diaphragm 5 also are clipped between loam cake 2 and the fixed base 8; Fixed base 8 is located between loam cake 2 and the oil nozzle 12, and throttling spring 10 is positioned at the top of spring pressuring plate 11, and spring pressuring plate 11 is stuck in the space of fixed base 8 and is positioned at the top of oil nozzle 12.The other end of oil nozzle 12 connects electric-spraying fuel pump 13.Diaphragm top board 4, diaphragm 5, regulating spool 6, diaphragm press table 7 constitute diaphragm unit.
The utility model electric-spraying fuel pump constant-current stabilizer arrives parameters needed with Flow-rate adjustment; When the electric-spraying fuel pump flow increased, liquid promoted the power that the throttling steel ball makes progress and increases, and promoted diaphragm unit simultaneously and moved up and reduce the volume that liquid flows into; Reduce liquid and flow into, reduce flow.When flow was low, liquid promoted the power minimizing that the throttling steel ball makes progress, and diaphragm unit with throttling steel ball pressed downward, increases the volume that liquid flows under the active force of Regulation spring, increased liquid and flowed into, the increase flow.Power through up-down adjustment changes the volume that liquid flows into, and makes constant flow in the parameter area of needs, reaches the effect of current stabilization, improves the rate of combustion of vehicle fuel, reduces the pollution that discharging is come, energy saving and protected physical environment.
Though more than described the embodiment of the utility model; But those skilled in the art is to be understood that; These only illustrate, and under the prerequisite of principle that does not deviate from the utility model and essence, can make numerous variations or modification to these mode of executions.Therefore, the protection domain of the utility model is limited appended claims.
Claims (2)
1. electric-spraying fuel pump constant-current stabilizer; It is characterized in that it comprises regulates screw, loam cake, Regulation spring, diaphragm top board, diaphragm, regulating spool, diaphragm press table, fixed base, throttling steel ball, throttling spring, spring pressuring plate, oil nozzle, regulates the top that screw is located at loam cake; Regulation spring is in the bottom of regulating screw; The therebetween of diaphragm is between diaphragm top board and diaphragm press table, and regulating spool is connected with the throttling steel ball after passing diaphragm top board, diaphragm, diaphragm press table, and fixed base is located between loam cake and the oil nozzle; The throttling spring is positioned at the top of spring pressuring plate, and spring pressuring plate is stuck in the space of fixed base and is positioned at the top of oil nozzle.
