Specific embodiment
In order to which the objects, technical solutions and advantages of the utility model patent are more clearly understood, below in conjunction with attached drawing and
The utility model patent is further elaborated in embodiment.
A kind of distribution turbine generation energy source station port fuel system, including fuel pump 1, bracket 2, motor 3, filter 4,
Overflow valve 5, pressure measuring tie-in 6, pressure gauge 7, two-position two-way electromagnetic directional valve 8, proportional reversing valve 9, flow sensor 10 and unidirectional
Valve 11, fuel pump 1 are connect with motor 3 by bracket 2, and filter 4 is set to 1 oil outlet of fuel pump and 9 oil inlet of proportional reversing valve
On the connected pipeline of mouth, the pollutant inside fuel oil can be filtered out, protects proportional reversing valve 9, flow sensor 10, check valve
11 are set in turn on the pipeline that 9 oil outlet of proportional reversing valve is connected with nozzle oil inlet, and flow sensor 10 can real-time detection
To the numerical value of fuel flow, PLC is fed back to, by computer operation, the control voltage of proportional reversing valve 9 is constantly adjusted, to change
Become the size of its spool aperture to change the fuel delivery of fuel oil, check valve 11 avoids hydraulic oil from flowing back, overflow valve 5, bi-bit bi-pass
Solenoid directional control valve 8 is arranged in parallel, the pipeline of overflow valve 5, the oil inlet of two-position two-way electromagnetic directional valve 8 and 1 oil outlet of fuel pump
It is connected, overflow valve 5, the oil outlet of two-position two-way electromagnetic directional valve 8 are connected with the oil return opening of system.Overflow valve 5 can guarantee to fire
The excessive high pressure fuel that oil pump 1 exports, the oil inlet of fuel pump 1 is returned to by overflow valve 5.
In the present embodiment, there are two proportional reversing valve 9 is arranged in parallel.When one of proportional reversing valve 9 when something goes wrong,
Still ensure that system worked well, the utility model is as described in Figure 1, and proportional reversing valve 9 is two-position four-way proportional reversing valve 9, left
Station is that working position, right working position are not that (when practical right working position works, oil inlet and one of actuator port are logical, so for working position
The actuator port fuel feeding is in nozzle afterwards；Another actuator port and oil return opening be it is obstructed, i.e., can only oil inlet for nozzle operation, no
Can oil return to fuel tank).Proportional reversing valve 9 controls flow, links and controls with proportional reversing valve 9 after 10 detection flows of flow sensor
System changes flow system flow to meet electricity generation system real-time requirement.
In the present embodiment, pressure measuring tie-in is provided on the pipeline that 1 oil outlet of fuel pump is connected with 9 oil inlet of proportional reversing valve
6 and pressure gauge 7.Pressure measuring tie-in 6 and pressure gauge 7 are provided on the pipeline that 9 oil outlet of proportional reversing valve is connected with nozzle oil inlet.
Pressure gauge 7 can display real-time the pressure of system fuel feeding, and pressure measuring tie-in 6 has the function of unidirectional cutoff, when pressure gauge 7 needs replacing
When, it can directly dismount, system fuel oil will not be revealed.
In the present embodiment, overflow valve 5, two-position two-way electromagnetic directional valve 8, proportional reversing valve 9 and flow sensor 10 are all set
It is placed in valve block 12.Overflow valve 5, two-position two-way electromagnetic directional valve 8, proportional reversing valve 9 and flow sensor 10 are all disposed within valve
Compact-sized, beautiful above block 12, debugging, detection, maintenance are all very convenient.
In the present embodiment, two-position two-way electromagnetic directional valve 8 is normally open valve.When motor 3 starts, the fuel oil of the output of fuel pump 1
It is returned directly to 1 oil inlet of fuel pump by two-position two-way electromagnetic directional valve 8, guarantees that 3 staring torque of motor is smaller；Normal fuel injection
When, two-position two-way electromagnetic directional valve 8 must be electrically turn off.
Embodiment described above and other legends only express a kind of embodiment of the utility model, only indicate that
Rather than limitation the utility model.For those of ordinary skill in the art, before not departing from the utility model design
It puts, various modifications and improvements can be made.Therefore, the protection scope of the utility model should be determined by the appended claims.
