Background
In the military industry field and the civil field, the tightness of a sealed cabin of equipment needs to be detected, and meanwhile, in order to ensure that electronic components and metal structural parts in the sealed cabin are not oxidized, inert gas needs to be filled for protection, the existing equipment has the following defects:
1) the volume is large, the occupied space is large, and the movement is inconvenient.
2) High cost and low cost performance.
3) The structure is more complicated and the maintenance is inconvenient.
Disclosure of Invention
The invention provides a micro nitrogen-filled airtight vacuum control device, aiming at solving the problems of large volume, high cost and complex structure of the existing nitrogen-filled airtight vacuum equipment.
The invention is realized by adopting the following technical scheme: miniature nitrogen gas airtight vacuum control device that fills, including the mounting base, be equipped with the passageway of ventilating in the mounting base, the passageway the place ahead left side of ventilating leads to out the mounting base and is equipped with the nitrogen gas adapter, nitrogen gas adapter department is equipped with the nitrogen gas valve of filling, the passageway the place ahead right side of ventilating leads to out the mounting base and is equipped with the vacuum adapter, vacuum adapter department is equipped with the vacuum valve, the passageway the rear of ventilating leads to out the mounting base and is equipped with the product adapter, the passageway department top of ventilating of product adapter is equipped with the pressure vacuum meter, the passageway right-hand member.
When the portable vacuum pump works, the portable vacuum pump is matched with a nitrogen cylinder with a pressure reducer for use, and the nitrogen adapter is connected with an outlet channel of the pressure reducer of the nitrogen cylinder; the vacuum adapter is connected with an inlet channel of the portable vacuum pump; the product adapter is connected with a tested product. The working process is as follows:
(1) filling nitrogen gas: and closing the vacuum valve and the exhaust valve, opening the nitrogen filling valve, enabling nitrogen to enter the tested product through the mounting base, displaying the pressure through a pressure vacuum meter on the mounting base, closing the air source when the specified pressure is reached, disconnecting the tested product, and opening the exhaust valve to discharge the residual nitrogen in the channel.
(2) Vacuumizing: and closing the nitrogen charging valve and the exhaust valve, opening the vacuum valve, vacuumizing the tested product through the mounting base, displaying the vacuum degree through a pressure vacuum meter on the mounting base, closing the vacuum pump when the specified pressure is reached, opening the exhaust valve to be communicated with the atmosphere to remove the vacuum degree, and disconnecting the tested product.
(3) Under the condition that the tested product needs to be vacuumized and filled with nitrogen, the nitrogen filling valve and the exhaust valve are closed firstly, the vacuum valve is opened to vacuumize the tested product, when the pressure reaches a required value, the vacuum valve is closed, the nitrogen filling valve is opened to fill nitrogen, the nitrogen source and the tested product are disconnected after the pressure reaches the required pressure value, and the exhaust valve is opened to release the residual nitrogen in the channel.
And (3) carrying out airtight inspection on the tested product by the method in the step (2) under the condition of pressure maintaining.
The invention has the following beneficial effects: by means of ingenious structural design, the device can complete various nitrogen-filled airtight vacuum operations. The invention has small size of the appearance structure and light weight, and solves the problem that the existing detection equipment is inconvenient to carry and occupies large space; the manufacturing cost is low, the cost performance is high, and the paint can be used in the military and civil fields; simple structure, reliable control and convenient maintenance. The invention has the advantages of simple structure, reliable control, convenient operation, convenient carrying, easy maintenance, wide application field, high cost performance and higher practical value.
