Valve can also be solenoid valve.
It please refers to shown in Fig. 4, the application method of discharge coefficient test gas circuit includes the following steps：
401, initial step.
The first two-bit triplet solenoid valve 40 and the second two-bit triplet solenoid valve 50 are in original state under initial step, this
When, second end B is connected to third end C, the 4th end D and the 6th end F connections.Certainly, the first two-bit triplet electromagnetism when original state
Valve 40 and the second two-bit triplet solenoid valve 50 can be at energized state or off-position, preferably be in off-position, and
The scope of protection of the utility model is explained and illustrated for state according to this.
402, aeration step.
After the product connector to be measured of product 80 to be measured access third connecting tube 23, start aeration step.Pass through at this time
Controller controls the first two-bit triplet solenoid valve 40 and is powered so that first end A is connected to third end C, the second two-bit triplet electromagnetism
Valve 50 keeps original state still in off-position, at this point, work air source is inflated by filling channel to product 80 to be measured,
Filling channel is followed successively by the first connecting tube 21, the first end of the first two-bit triplet solenoid valve 40 according to the air flow direction of work air source
A and third end C, the second connecting tube 22, the 4th end D of the second two-bit triplet solenoid valve 50 and the 6th end F and third connecting tube
23, the air flow direction for the air source that works is as shown the direction of arrow in Figure 2.
Why aeration step is arranged before testing product 80 to be measured to be：Inflation at the moment, first connect
The air-flow that the loading line that take over 21, the second connecting tube 22 and third connecting tube 23 are constituted is poured into product 80 to be measured is very big,
If being directly connected to flow sensor 70 to measure, the serious excess of flow sensor 70 can be caused even to damage, filled
During jia bombardier is rapid, stream pressure is detected by pressure sensor 60, after inflation starts, passes through controller (internal clocking
Chip) or timing device passes through pressure sensor to gas replenishment process progress timing when reaching preset inflationtime accordingly
60 detection data can tentatively judge whether product 80 to be measured is abnormal.The timing of the step and be switched in next step can be with intelligence
It can complete, such as the time relay or timer realization are set between controller and two two-bit triplet solenoid valves.
403, testing procedure.
After inflation, testing procedure is executed, controlling the second two-bit triplet solenoid valve 50 by controller is powered, and makes the 5th
E and the 6th end F connections are held, and the state of the first two-bit triplet solenoid valve 40 is not had to be limited, state can be switched on,

Product 80, TCH test channel are followed successively by test pipeline 30, flow sensor 70, the second two-bit triplet solenoid valve 50 according to air flow direction
With third connecting tube 23, air flow direction is the arrow direction of Fig. 3, is then treated by flow sensor 70 and pressure sensor 60
Product 80 is surveyed to be tested.
Similarly, timing is carried out to test process, after completing the testing time, passes through 70 He of controller output flow sensor
The detection data of pressure sensor 60, when reaching the related setting parameter being pre-stored in controller, then product 80 to be measured is qualified, instead
It, then it is unqualified.
Why inflationtime and testing time are set, be because moment flow and pressure value there may be certain mistakes
Difference, because being compared with default related data by the flow and pressure value for obtaining the unit interval in a period of time so that
Test is more accurate, meanwhile, according to setting inflationtime and testing time, all similar products can also be facilitated to carry out lateral ratio
Compared with.
404, steps of exhausting.
After being completed, controls the first two-bit triplet solenoid valve 40 and the second two-bit triplet solenoid valve 50 restores initial shape
State is in off-position, at this point, second end B is connected to third end C, the 4th end D and the 6th end F connections.Product 80 to be measured
Interior gas is discharged by exhaust passage, and exhaust passage is followed successively by third connecting tube according to the gas flow in product 80 to be measured
23, the 6th end F and the 4th end D of the second two-bit triplet solenoid valve 50, the second connecting tube 22, the first two-bit triplet solenoid valve 40
Third end C and second end B and exhaust outlet 12, the arrow direction of gas flow such as Fig. 1 of exhaust；After exhaust, removes and wait for
Product 80 is surveyed, initial step is returned to.It repeats the above steps, the discharge coefficient of other products to be measured can be tested.
The utility model by the first two-bit triplet solenoid valve 40, the second two-bit triplet solenoid valve 50 and associated pipe,
The actions such as inflation, test, exhaust are executed, inflation action, air-flow is in the case where being not passed through flow sensor, to product 80 to be measured
It is filled with the gas of certain pressure so that filling channel is in the state of flow balance and stability, and flow sensor is avoided to open
It is in when beginning work and outranges state.Test action by flow sensor detect TCH test channel in gas flow, and by
At the time of timer accurately controls reading numerical values, all products is facilitated to carry out lateral comparison.
The above embodiment is only preferred embodiments of the present invention, cannot be protected with this to limit the utility model
