What is the way to use automatic and rusty life jackets.

principle of automatic inflatable life jacket

This kind of life jacket is made of high -intensity Waterproof material. The inflatable life jacket is composed of sealing inflatable vest, micro -pressure gas cylinders, and fast inflatable valves. It is often used in the possibility of falling into the water.

Under normal circumstances (not inflatable), the entire inflatable life jacket is Hanging on the back of the shoulder like a strap. Because the volume is small, it does not hinder people's homework.At all times, or automatically expand and inflatable (automatic inflatable life jacket) according to the action of water, or by pulling a cable (manual inflatable life jacket) on the man-charged air valve, it can be inflated into 8-15 kg of buoyancy within 5 seconds.Safe clothes; life jackets hold up the human body upward, so that the head and shoulders are exposed to the surface, so as to obtain safety protection in time.

The automatic inflatable life jacket will soften the water sensitive element in the automatic device after the water is immersed in the water after falling into the water, loses the needle in the needle, and the spring stretchs pushes the piercing needle to pierce the cylinder sealing film carbon dioxide gas to fill the airbag and generate buoyancy.

How to use automatic inflatable life jacket

1. Check before wearing

(1) Check whether the life jacket is damaged to ensure that the life jacket has no cracks or thorns.This type of damage on the outer cover indicates that the inflatable gas chamber may have been in contact with the parts that cause damage.If these flaws are found, you cannot continue to use it before the maintenance test.

(2) Check the status of the automatic inflatable device. The indicator components of the automatic inflatable device will inform you whether the automatic inflatable device has been properly installed.Please refer to the inflatable device indicator component inspection instructions near the automatic inflatable device.

(3) Check the carbon dioxide cylinder. When the automatic inflatable device works, the cylinder equipped with carbon dioxide gas will ventilate the life jacket.The size of the installed carbon dioxide cylinder needs to be checked correctly and has not been used before.When checking the cylinder, unscrew the cylinder and observe the screw mouth plane.There are no components that display the interior gas on the steel cylinder.If the screw mouth plane is damaged, the cylinder needs to be replaced.Refer to the specifications of the homepage product specifications to select the proper size of the steel cylinder, including the size of the threaded mouth and the weight of the interior carbon dioxide.If the cylinder is normal, it is necessary to correctly return to the automatic inflatable device.Additional instructions for CO2 steel cylinders:

Before installing the CO2 cylinder, the automatic inflatable device without proper installation will cause an immediately inflatable.

CO2 steel cylinders can only be inflated once and cannot be used again.

The protective plating layer of the CO2 steel cylinder may be corroded after placing the environment or for a period of time. At this time, the CO2 steel cylinder will begin to show some signs of rust.To replace the CO2 steel cylinder.

2. Install and indicate component inspection

The last page of the instructions for use provides the automatic inflatable device for life jackets and then install and indicate component inspection instructions.

3. Putting instructions after inflatable

A plenty of life will be difficult to put on.Exhaust through the mouth blowing Tube until it is easy to wear.See page 4 exhaust description.Put as described above and blow it out.

Before use, practice closed fastening and adjustment steps as follows: Stretch into the left arm first, then reach into the right arm, close the fastener, and finally tighten the strap.

4. Instructions for inflatable

(1) Automatic inflation: Automatically inflatable device after falling water will automatically inflatable within 5 seconds.

(2) Portum inflation: The mouth blowing pipe is located on the left side of the user.Open the left side of the life jacket, pull the mouth blowing duct straight, and blow the air until the airbags harden.If the airbags become softer due to carbon dioxide infiltration (after a period of time, the cylinder gas is lost normally), it is necessary to maintain sufficient buoyancy through the mouth blowing.

(3) Frozen conditions: In the condition of temperature below 40 C, the airbags are not hard. In addition to automatic inflatable, it is necessary to perform mouth blowing.The carbon dioxide gas at this temperature will be longer.

(4) Other inflatable instructions: Be careful not to blow the full filling and use carbon dioxide cylinders to manually inflatable.Repeating carbon dioxide ventilation after mouth blowing will destroy life jackets.You must never use the air pump or air compressor to get angry with life jackets.Carbon dioxide gas loss is more lost than air inflation, so it is necessary to supplement it as soon as possible through the mouth blowing system.

5. exhaust description

Plug the mouth blow valve (at the end of the mouth blowing Tube) with the end of the hood on the mouth blowing pipe. While pressing the port blowing valve, gently discharge the gas from the airbag.Can not exhaust the life jacket airbag.If the mouth blowing valve is kept open for some reason, press the valve multiple times.If it cannot be released, the life jacket needs to be repaired.

6. Other instructions

(1) Unless you are in the cabin, you must put on a life jacket from time to time.

(2) Avoid all unnecessary activities that will wear a life jacket to avoid exposure.

(3) Be careful when used around the sharp object.

(4) If the automatic inflatable life jacket falls into the water or places the inflatable system in an unnecessary water spraying environment, it will cause accidental inflation.
