Background technique
Automobile fuel pump assembly is the fuel oil for providing specified pressure to the oil-fired system of motor car engine.And pressure regulator valve is the important component part of automobile fuel pump assembly, it is installed on return line, its effect is that the unnecessary high pressure fuel of oil-fired system by being supplied to motor car engine carries out pressure regulation and then is back in fuel tank, so that oil pump is again to the oil-fired system fuel feeding of motor car engine.
The structure of existing automobile fuel pump assembly pressure regulator valve has generally comprised valve body, diaphragm, pressure adjusting spring and valve ball, described diaphragm arrangement is in valve body and body cavity is separated into epicoele and cavity of resorption, described valve body is provided with the oil inlet passage communicated with cavity of resorption and oil discharge passage, in described cavity of resorption, the inner of oil discharge passage is provided with valve seat, on described diaphragm, interlock is fixedly installed ball seat, the lower end of this ball seat arranges the valve ball that ball pivot is provided with lower end and valve base sealing adaptation, the upper-end surface of described diaphragm is linkedly set with spring seat, described pressure adjusting spring is arranged in epicoele, and the two ends up and down of this pressure adjusting spring abut with the inner roof wall of valve body and spring seat effect respectively.This traditional pressure regulator valve operationally, the fuel oil of high pressure enters into the cavity of resorption of valve body from oil inlet passage, and the pressure relying on fuel oil overcomes the active force of pressure adjusting spring by diaphragm upwards jack-up, thus make diaphragm drive valve seat moves, valve ball and valve seat be separated, and then fuel oil pressure regulation is discharged from oil discharge passage.
This traditional pressure regulator valve is in-problem: the outlet of oil discharge passage is arranged at cavity of resorption place, the flow velocity that fuel oil flows out after pressure regulation from oil discharge passage is very fast, these fuel oils with flow velocity are filled in automotive oil tank fast, easily cause fuel oil violent play in fuel tank, there is potential safety hazard.
Summary of the invention
The purpose of this utility model is the shortcoming and defect existed to overcome prior art, and provides a kind of fuel-displaced formula pressure regulator valve that effectively can reduce the automobile fuel pump assembly of the fuel flow rate of discharging in oil discharge passage.
For achieving the above object, the technical solution of the utility model includes valve body, diaphragm, pressure adjusting spring and valve ball, described diaphragm arrangement is in valve body and body cavity is separated into epicoele and cavity of resorption, described valve body is provided with the oil inlet passage communicated with cavity of resorption, on described diaphragm, interlock is fixedly installed diaphragm seat, this diaphragm seat is provided with the oil discharge passage being communicated with cavity of resorption and epicoele, described diaphragm seat is provided with the valve seat being positioned at cavity of resorption relative to the lower end of oil discharge passage, the interior diapire of described valve body is fixedly installed ball seat, ball pivot chamber is provided with in the upper-end surface of this ball seat, the valve ball of upper end and valve base sealing adaptation is provided with in this ball pivot chamber, the upper-end surface of described diaphragm is linkedly set with spring seat, described pressure adjusting spring is arranged in epicoele, and the two ends up and down of this pressure adjusting spring abut with the inner roof wall of valve body and spring seat effect respectively, the roof of described valve body is provided with the oil outlet communicated with epicoele.
By this setting, fuel oil is after pressure regulation, enter into epicoele from the oil discharge passage of diaphragm seat, fuel oil is effectively cushioned in epicoele, and the speed of fuel oil is declined greatly, then fuel liquid level rises gradually, and discharge from the oil outlet of valve body roof, thus, the fuel flow rate after pressure regulator valve pressure regulation greatly can be reduced, prevent it from scurrying in fuel tank at a high speed, improve Security.
Further setting also includes the non-return filtering mechanism be arranged at outside oil inlet passage, this non-return filtering mechanism includes the one-way valve of one-way conduction in export-oriented oil inlet passage and is arranged at the filter core in liquid feeding end direction of one-way valve, described filter core is taper filter core, this taper filter core arranges multiple contaminant filter hole, described one-way valve includes check valve body, nonreturn valve core, valve core reseting spring and one-way valve base, one-way valve runner and the one-way valve seat being arranged at one-way valve tunnel inlets side is provided with in described check valve body, described one-way valve base is fixedly installed on the one-way valve runner exit side of check valve body, this one-way valve base is provided with the base runner communicated with one-way valve runner, described one-way valve base center is provided with slippage cylinder, the outer end slippage of described nonreturn valve core is arranged in slippage cylinder, and the inner of this nonreturn valve core forms the one-way sealing pair be sealed and matched with one-way valve seat, described valve core reseting spring is arranged in slippage cylinder, the two ends of this valve core reseting spring abut with nonreturn valve core and the effect of one-way valve base respectively.
One-way valve is set up in this setting, when pressure regulator valve does not work, prevents the fuel oil be deposited in valve body cavity of resorption from flowing backwards outside oil inlet passage, prevents the fuel flow returns of different pressures in motor, affect the normal operation of motor.Arrange filter core in the liquid feeding end direction of one-way valve, prevent the impurity in fuel oil from entering in pressure regulator valve, protection valve ball is not damaged, improves its working life.
In sum, the utility model has the advantages that and can greatly reduce the fuel oil rate of outflow, improve Security, long service life.
Below in conjunction with specification drawings and specific embodiments, the utility model is described further.
