Abstract

The invention discloses a method and system for testing sealing performance of a valve. The method comprises the steps that the internal and external air pressure difference of the valve to be tested is obtained through a pressure difference sensor, wherein the valve to be tested is in the closed state, and the internal and external air pressure difference is the difference of the value of the air pressure inside the valve to be tested and the value of the air pressure outside the valve to be tested after air inflation and pressurization are carried out on the valve to be tested in the closed state; whether the internal and external air pressure difference is larger than a preset value or not is judged through a CPU, so that a first judgment result is obtained; when the first judgment result shows that the internal and external air pressure difference is larger than the preset value, information that the sealing performance of the valve to be tested is qualified through testing is displayed; when the first judgment result shows that the internal and external air pressure difference is equal to or smaller than the preset value, information that the sealing performance of the valve to be tested is disqualified through testing is displayed. When the method and system for testing the sealing performance of the valve are adopted, automatic testing of the sealing performance of the valve can be achieved, and testing efficiency is improved.

Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Based on the embodiment in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
For above-mentioned purpose of the present invention, feature and advantage can be become apparent more, below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
First it should be noted that, the valve in the present invention, can be solenoid valve, can be also motor valve.Solenoid valve generally only has two states of open and close, and motor valve can be controlled it and open certain aperture.
Fig. 1 is the process flow diagram of the embodiment of the method 1 of testing valve door sealing performance of the present invention.Described method is applied to the electronic equipment with differential pressure pickup and CPU element.Differential pressure pickup is a kind of sensor that is used for measuring difference between two pressure.As shown in Figure 1, the method can comprise:

Described valve to be measured can at least have opening and closing two states.When described valve to be measured is during in closed condition, described valve to be measured should be in theory have bubble-tight.
Can adopt aerating device to inflate the valve in closed condition, because the valve described to be measured in closed condition has impermeability, so along with being filled with the increase of gas, the atmospheric pressure value of described valve internal to be measured can raise.
After described differential pressure pickup is connected with described valve to be measured, can sense the poor of the atmospheric pressure value of described valve internal to be measured and the atmospheric pressure value of described valve to be measured outside.
Step 102: judge that by described CPU element whether described air pressure difference is greater than default value, obtains the first judged result;
The technological requirement of supposing valve to be measured is that the valve internal in closed condition is 2 atmospheric pressure with the outside pressure difference value that can bear, when the described air pressure difference measuring when differential pressure pickup is greater than 2 atmospheric pressure, the first judged result can be yes, when the described air pressure difference measuring when differential pressure pickup is less than 2 atmospheric pressure, the first judged result can be no.
It should be noted that, in order to obtain more accurate and stable test result, in the time that described air pressure difference is greater than default value, can export described the first judged result at once, can work as described air pressure difference and continue to be greater than default value time, then export the first judged result of "Yes" in the one section of Preset Time stopping after inflating pressure.
This be because, in the time that aerating device continues valve to inflate, even the sealing property defectiveness of valve, exist and leak, if but the aeration speed of aerating device is very fast, be greater than the leakage rate of valve, the atmospheric pressure value in valve still can raise, thereby makes described air pressure difference reach default value.Affect the accuracy of test result for fear of above-mentioned situation, so, can be in the time stopping when described air pressure difference continuing to be greater than default value in one section of Preset Time after inflating pressure, then export the first judged result of "Yes".
Step 103: when described the first judged result is when being, show the sealing property test passes information about described valve to be measured;
Can point out test result by acoustic information or visual information.For example, can point out test result by LED light, when test result is while being qualified, can control described LED light and show greenly, in the time that test result is defective, can controls described LED light and show red.Can also point out by display screen, for example, when test result is while being qualified, can show screen display " qualified " printed words, or show that screen display is to hooking pattern; When test result is while being defective, can show screen display " defective " printed words, or show screen display fork pattern etc.
Step 104: when described the first judged result is while being no, show the sealing property test failure information about described valve to be measured.
In sum, the method of the testing valve door sealing performance of the present embodiment, obtain the inner and outer air pressure difference of the valve to be measured in closed condition by differential pressure pickup, judge by described CPU element whether described air pressure difference is greater than default value, again according to judged result, detecting information is pointed out, can realize the automatic test for valve seal performance, improve testing efficiency, and, owing to carrying out obtaining of air pressure difference by differential pressure pickup, can also avoid manual testing time, staff produces the error increase that fatigue causes.

Step 202: judge that by described CPU element whether described air pressure difference is greater than default value, obtains the first judged result;
Step 203: when described the first judged result is when being, the Show Color of the described performance information pilot lamp corresponding with described valve to be measured is adjusted to green;
Step 204: when described the first judged result is while being no, the Show Color of the described performance information pilot lamp corresponding with described valve to be measured is adjusted to redness.
