Inflatable boat, also known as inflatable assault boat, is a kind of inflatable assault boat. When not in use, the gas will be released and preserved. What gas is the inflatable boat filled?

In the past, the gas in inflatable boats was hydrogen, but because hydrogen has certain risks and risks of explosion, helium is used instead. Helium is a rare gas with smaller density than air and stable chemical properties. It is a safe gas. It is commonly used as protective gas in chemical experiments or factories. Of course, it is also possible to use ordinary air without affecting actual use.

If the inflatable boat is not full of air, it cannot travel on the water, but it will not work if it is in a saturated state of inflation, which will accelerate aging and damage. Therefore, it is necessary to inflate and deflate regularly. How can the inflatable boat inflate and deflate?

1. Bleed method: find the position of the air nozzle of the inflatable boat, unscrew the horizontal bar outside the air nozzle, then look at a spring-like protrusion inside, press it down, rotate counterclockwise and then release it.

2. Inflation method: Before inflating, release the previous gas. After deflating, twist the spring-like protrusion in the opposite direction, and then inflate the assault boat with the equipped inflator. Attention should be paid when inflating. The inflatable boat buoy is divided into multiple air chambers, and the interior is separated by diaphragms. Pay attention to uniformity when inflating. Do not fill one air chamber at a time, and first inflate each air chamber to 60%, turn back and fill up again.

Inflatable boats need to be inflated, but pay attention to the air pressure when inflating. Ordinary car tires do not reach a certain air pressure, and the wheels are biased. Inflatable boats are inflated only to provide buoyancy and molding, so there is little requirement for inflatable air pressure, as long as it does not exceed the specified air pressure.

Generally speaking, the air pressure of the inflatable boat is suitable for nine of the standard air pressure. When inflating, the buoy feels hard.
