Description
Technical field
The utility model is related to Valve EGR test fixture field, specifically a kind of for the resistance to of Valve EGR
Long test device.
Background technology
At present when carrying out durable test for Valve EGR, due to that can not make it that stabilization is produced in durable test loop
Negative pressure, it is therefore desirable to especially purchase the durable test that large-scale intelligent pressure regulating equipment carries out Valve EGR, so increase
Cost is added.
The content of the invention
The utility model is overcomes the deficiencies in the prior art, and design is a kind of to be directed to Valve EGR and can quickly exist
The durable test device of stable negative pressure is produced on Valve EGR, to substitute the large-scale intelligent used in current durable test device
Voltage adjusting device, reduces cost.
To achieve the above object, a kind of durable test device for Valve EGR is designed, including function signal occurs
Device, Venturi tube, source of the gas, gas circuit, it is characterized in that：The source of the gas connects gas circuit, and the gas circuit is sequentially connected air pressure from front to back
Regulating valve, two Venturi tubes and gas tank in parallel are simultaneously ultimately connected to Valve EGR, and the Valve EGR passes through control
Output line contiguous function signal generator.
Barometer is additionally provided with gas circuit between the gas tank and Valve EGR.
The utility model is compared with the existing technology, simple in construction, easy to use；Connected by specific loop, can be fast
The negative pressure that stabilization is produced on Valve EGR of speed, can effectively carry out the durable test of Valve EGR, eliminating must
The drawbacks of large-scale intelligent voltage adjusting device must being used.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Referring to Fig. 1, wherein, 1 is source of the gas, and 2 be air pressure regulator, and 3 be Venturi tube, and 4 be gas tank, and 5 be barometer, and 6 are
Valve EGR, 7 be function signal generator, and 8 be gas circuit.
Embodiment
The utility model is described further below according to accompanying drawing.
As shown in figure 1, the connection of source of the gas 1 gas circuit 8, the gas circuit 8 is sequentially connected air pressure regulator 2, two from front to back
Individual Venturi tube 3 in parallel and gas tank 4 are simultaneously ultimately connected to Valve EGR 6, and the Valve EGR 6 is defeated by control signal
Outlet contiguous function signal generator 7.
Barometer 5 is additionally provided with gas circuit 8 between the gas tank 4 and Valve EGR 6.
The utility model realizes the stabilization of negative pressure in loop in use, connected by specific loop.Source of the gas 1 passes through gas
Regulating valve 2 is pressed, then negative pressure is produced by two Venturi tubes 3 arranged side by side, voltage stabilizing regulation is carried out by the negative pressure of 4 pairs of generations of gas tank.
Negative pressure value of the output on Valve EGR 6 is read on barometer 5.Valve EGR 6 is controlled by function signal generator 7
Open with closing.The durable test of Valve EGR can be effectively carried out after use, eliminating must be adjusted using large-scale intelligent
The drawbacks of pressing equipment.
