If the sling launching device cannot be used, the life can be saved by the throwing type. The inflation mode of the sputum is automatically inflated and deployed.
The life raft is usually stored in the FRP storage cylinder and installed on the special truss of the ship's side. The raft can be directly thrown into the water. The life raft can be automatically inflated and formed for the people in distress. If the ship sinks too fast, it will be too late. When the ship is thrown into the water, when the ship sinks to a certain depth, the hydrostatic pressure release device on the truss will automatically unhook, releasing the life raft, and the life raft will automatically float and form.
The life raft hydrostatic pressure release device consists of three parts: a chain hook, a fragile rope and a release. JSQ-III hydrostatic pressure release device consists of stainless steel bellows cover, bellows tray, spring, bracket plate, mandrel, steel bowl, safety hook and rubber diaphragm. When the releaser sinks with the ship, the hydrostatic pressure of seawater Acting on one side of the diaphragm, the back of the diaphragm is an airtight chamber. The rubber diaphragm is subjected to the hydrostatic pressure. The compression spring drives the mandrel to move inward, causing the hook to slide out and rotate from the mandrel end, so that the shackle is disengaged, and the life raft is separated from the hull and inflated.
Use of life raft hydrostatic pressure releaser
1. Automatic release: The hydrostatic pressure release device will automatically cut off the connecting rope between 1.5 and 4 m in seawater to release the life raft. The inflated expansion of the liferaft is then initiated as the first cable is tightened, with the result that the weak ring is pulled apart, leaving the liferaft completely detached from the hull.
2, manual release: open the slip ring to put down the life raft. Subsequent tightening of the first cable will initiate the inflation expansion process of the liferaft, with the result that the first cable is manually cut off, leaving the liferaft completely detached from the hull.
