Specific embodiment
With reference to the accompanying drawing, it elaborates to specific embodiment of the present utility model, in order to the art
Technical staff understands the utility model.It should be apparent that embodiment described below is only a part of the utility model
Embodiment, rather than whole embodiments.Do not depart from the attached claims limit and determine the utility model spirit and
In range, those of ordinary skill in the art are not making any creative work every other embodiment obtained, all belong to
In the protection scope of the utility model.
As shown in Figure 1, the pressure reducer device for detecting performance includes high pressure gas cylinder, high pressure gas cylinder by the first output channel with
The entrance of pressure reducer to be measured is detachably connected, and is disposed with high pressure valve and inlet pressure transducer in the first output channel, to
The level-one of survey pressure reducer is intracavitary to be provided with level-one cavity pressure sensor, and the outlet of pressure reducer to be measured passes through the second output channel and combustion
The connection of gas common rail, the outlet of pressure reducer to be measured are detachably connected with the second output channel, high pressure valve, inlet pressure transducer, one
Grade cavity pressure sensor, outlet pressure sensor, pressure reducer to be measured and combustion gas common rail are connect with controller respectively, controller connection
There is display control device.
When implementing, the preferred display control device of this programme low, low power consumption LCD display for the distortion factor, and LCD is shown
It is provided with model selection key on screen, is selected for staff according to the concrete model of pressure reducer to be measured, and to control
Device sends the order for starting test, so that controller calls normal data conduct pair corresponding with the model automatically in test process
Than.First output channel can be connect with the entrance of pressure reducer to be measured by spring hoop, the outlet of pressure reducer to be measured and second
Output channel can be connected by spring hoop.
In addition, controller is connect with buzzer siren, for detecting warning note when rejected product.
The utility model selects corresponding test pattern by display control device, controls high pressure valve using controller and combustion gas is total
The working condition of rail, the different operating conditions of real simulation pressure reducer application in the car.And by controller under different operating conditions
Inlet pressure, level-one cavity pressure and the outlet pressure of pressure reducer are compared with the normal data being arranged inside controller and are examined
It surveys as a result, in conjunction with inlet pressure level, the level-one chamber under display control device real-time display operating condition different with the pressure reducer in record test
Pressure value, exit pressure levels and testing result, so that staff filters out rejected product in time.
Wherein, the different operating conditions of simulation can specifically include idling work state, big flow working condition and quiescent operation
State.When high pressure valve is opened, pressure reducer is opened, and combustion gas common rail is opened with 800 turns of opening pulsewidths for the working condition of 10ms
For idling work state；When high pressure valve unlatching, pressure reducer unlatching, and combustion gas common rail opens the work that pulsewidths are 10ms with 3000 turns

After controller receives beginning test command, automatically controls the utility model and successively simulate above-mentioned three kinds of operating conditions.
Specifically, the MCU of controller can select the MCU of model MC9S12ET256, inlet pressure transducer, level-one
Cavity pressure sensor and outlet pressure sensor can select the pressure sensor of model BP93420IB, and combustion gas common rail can
To select the combustion gas common rail of model OMVL.And by taking the pressure reducer of model R06 as an example, its standard value under idling work state
Are as follows: inlet pressure 35-40bar, outlet pressure 1.88-193bar, level-one cavity pressure 4.5-9.5bar；Big flow working condition
Its lower standard value are as follows: inlet pressure 35-40bar, outlet pressure 1.7-1.9bar, level-one cavity pressure 4.5-9.5bar；Static work
Make its standard value of state are as follows: inlet pressure 35-40bar, outlet pressure 1.95-2.15bar, level-one cavity pressure 4-10bar.Work as survey
There are the data of over range during examination, that is, judges this pressure reducer to be measured for rejected product.
