Specific embodiment
The present invention is described in further details below with reference to Figure of description and specific embodiment.
As depicted in figs. 1 and 2, a kind of embodiment of big orifice fast-response High Voltage air delivery device of the present invention, gas transmission dress
It sets including leading portion appendix 1, middle section appendix 2 and back segment appendix 3, is connected between leading portion appendix 1 and middle section appendix 2
Normally open solenoid valve 4 is connected with normally closed solenoid valve 5, back segment appendix 3 and test sheet between middle section appendix 2 and back segment appendix 3
Member 6 connects.Air delivery device of the invention is made of three sections of appendixs and two groups of guide electromagnetic valves, compared to traditional direct drive type electro
Magnet valve forms pipeline, and the straight line pipeline being made of guide electromagnetic valve is able to achieve the big orifice of three sections of appendixs, with gas transmission
Rate height and the strong feature of bearing capacity, meet the basic demand of High Voltage cold air quick washing load test；Using normally opened electricity
The bivalve combination of magnet valve 4 and normally closed solenoid valve 5, normally open solenoid valve 4 and normally closed solenoid valve 5 are able to achieve independent opening and closing, both mention
The reliability of high control in turn ensures the fast opening and closing of high pressure gas appendix, meets the load examination of High Voltage cold air quick washing
Test the strict demand to inflationtime (about 100ms).
In the present embodiment, leading portion appendix 1, middle section appendix 2 are identical with the caliber of back segment appendix 3 and caliber is greater than
80mm；The latus rectum of normally open solenoid valve 4 and normally closed solenoid valve 5 is identical as three sections of calibers of appendix.In the structure, latus rectum is all larger than
80mm realizes the big orifice of device, ensure that the high gas transmission rate of test.
As shown in figure 3, gas transmission method of the invention, is carried out with above-mentioned big orifice fast-response High Voltage air delivery device, packet
Include following steps:
S1: installation: the leading portion appendix 1 of air delivery device is connect with gas source unit, by the back segment appendix 3 of air delivery device
It is connect with test unit 6；
S2: it preparation gas transmission: opens normally open solenoid valve 4 and closes normally closed solenoid valve 5, make high pressure gas by leading portion appendix 1
Into high pressure gas terminates in 5 position of normally closed solenoid valve；
S3: gas transmission impact: normally open solenoid valve 4 and normally closed solenoid valve 5 are opened, enters high pressure gas by back segment appendix 3
Test unit 6 carries out Impulsive load to it；
S4: it closes valve group: closing normally open solenoid valve 4 and normally closed solenoid valve 5, high pressure gas is made to terminate in normally open solenoid valve 4
It sets.
In this method, before test, external system is powered off to two solenoid valves of big orifice fast-response High Voltage air delivery device,
Normally open solenoid valve 4 is in the open state, and normally closed solenoid valve 5 is in close state, and gas circuit is obstructed at this time, and high pressure gas terminates in normally closed
Type solenoid valve；When test, external system is powered to the normally closed solenoid valve 5 of big orifice fast-response High Voltage air delivery device, normally closed electricity
Magnet valve 5 is quickly opened, and gas circuit is connected at this time, and high pressure gas is from normally closed solenoid valve 5 to test unit 6(simulated engine) inflation.
In solenoid valve arrangement, it is contemplated that the shorter gas transmission distance the more advantageous when test, therefore after test unit 6 is located at air delivery device
Section, meets the inflation basic demand of high pressure gas quick washing load test；After the completion of test, external system is fast to big orifice
The energization of normally open solenoid valve 4, the power-off of normally closed solenoid valve 5 of High Voltage air delivery device are responded, 4 quick closedown of normally open solenoid valve is normally closed
5 quick closedown of solenoid valve, gas circuit is obstructed at this time, and high pressure gas terminates in normally open solenoid valve 4.
In the present embodiment, in step s 4, normally open solenoid valve 4 can be closed prior to normally closed solenoid valve 5.Since high pressure gas is fast
Fast Impulsive load test requirements document inflationtime is very short (about 100ms), considers that solenoid valve opens or closes movement and needs a timing
Between, therefore air delivery device sets up the valve combination of normally open solenoid valve 4 and normally closed solenoid valve 5.After on-test, even if normally closed electricity
Magnet valve 5 just opens a part and air test is completed, and also can close gas transmission to the energization of normally open solenoid valve 4 by external system
Channel avoids the problem of being completed to open and close the time by single solenoid valve too long and led to test failure.Such valve
The reliability that Combination Design had both improved control in turn ensures the fast opening and closing of high pressure gas transfer passage.
