The life-saving valve is usually packaged and stored in the FRP storage cylinder and installed on the special raft for ship's side. It can throw the valve directly into the water. The life-saving valve can automatically bulge and form for the passengers in distress. If the ship sinks too fast, it can not throw the valve into the water. When the ship sinks to a certain depth under the water, the hydrostatic pressure on the raft will be high. The releaser will automatically decouple and release the lifesaving valve. The lifesaving valve will float out of the water surface and automatically expand and form.
