Inch High Pressure Diving Regulator
Inch High Pressure Diving Regulator
Diving equipment
There are a few key pieces of equipment required for any dive, and other equipment which are used for more difficult diving conditions. Beginners and novice divers, however, will certainly need the following:
Mask
The human eye can not see clearly through the water for a pocket of air is necessary to maintain the vision underwater. A diving mask is like a large pair of goggles with a bead of silicone around. It also includes a pocket of silicone / seal of the nose, to prevent the user inadvertently trying to breathe through the nose and sucking water instead. diving masks are designed to withstand higher pressures found underwater, if a mask with snorkel is not suitable for diving.
Fins
Others become quite shirty if you refer to fins as "flippers", so make sure you get your terminology right effort! physics, such as swimming, uses energy and oxygen as fuel energy is needed, so people breathe more heavily when making exercise. Underwater, the diver wishes to conserve energy to make the air in the bottle last longer. Fine, then, are used to swim under water without effort as possible. Fins are large, flexible blades attached to the feet, providing maximum propulsion in the water during exercise minimum physical. There are two basic types of fins: fins of shoes fit on bare feet, like a slipper, the fins have a strap pocket foot with a strap that fits around the heel and are worn with boots.
Protective Clothing
Even in hot water, some form of protective clothing is necessary. There are four main types: -
• A suit of skin is a thin layer that protects the body from abrasion, either from the equipment worn or brush the rocks, corals, etc. A suit of skin is not the water is warmer.
• A combination offers some thermal protection and protection against abrasion. Wet suits are available with long or short arms and legs and in a range of thicknesses. Made of neoprene, a wetsuit allows water to flush through it, holding a thin layer on the skin, which heats the body, providing a means of defense against water temperatures a bit cooler.
• A semi-dry suit is a bit like a combination diving, but seals around the neck, wrists and ankles. water gets inside the suit and then be trapped warmed by the body. A semi-dry suit provides thermal insulation than a wetsuit.
• A dry suit is used for diving under cold water and do not allow water penetration at all. A dry suit has built in boots and seals around the wrists and neck, inside the combination of the body remains dry. Additional thermal protection is worn under a drysuit, as heat under layers. Drysuits are made from either neoprene or membrane triple thick wetsuits tend to be slightly warmer than membrane, the membrane adapts well allow greater freedom of movement. When hoods diving in cold water, and neoprene gloves are generally also covered for extra warmth. Special training is necessary before diving into a dry suit.
Buoyancy compensation device
There are several types of buoyancy compensator device (BCD), sometimes called BCD, BCS (buoyancy compensators), stabbing (stabilizer) jackets and wings. All work the same way. The BCD is worn as a jacket and is composed of air bladders inside a pipe to add or remove air bladder, a loop system for holding a bottle of air and usually a few pockets and D-rings for holding other equipment. The air is added or removed from the bladders of internal control buoyancy under water and the rate of descent and ascent to and from the surface.
Weight
A human being is naturally bearer, and even during the execution of a cylinder Diving will not automatically heavy underwater well. To counter this natural energy, therefore, the divers wear lead weights or on a carpet in a harness or in the pockets of their BCD. While under the water a small amount of air is added to the BCD to keep the diver off the bottom or depth they chose, and while on the surface of the BCD is filled with air to offset the negative effect of the weighting.
Cylinders
Unlike to popular belief, the scuba tanks to contains no oxygen, they contain air. The air is compressed and held in the cylinder pressure (measured in pounds per square inch (psi) or bar) by a valve on top. The cylinders are usually made of steel or aluminum and are available in a range of sizes, measured in cubic feet or liters. The advantage of a larger cylinder that contains more air, and thus the diver can stay under water longer, the downside is the heaviest. All dive cylinders must be periodically inspected and tested by independent testing facilities accredited to ensure they are safe.
Regulators
Regulators, often called simply "regs" are more correctly called "a set of regulators," because there are several components. The air in the cylinder is maintained at very high pressure, which humans can not breathe, so that the "first step ", which includes a clip that attaches to the cylinder reduces the pressure of the air at about 140psi/10 bar ambient pressure (ambient pressure increases with depth). Attached to the first stage are a series of high pressure hoses. In a typical set up for a novice diver, one pipes will feed "for the BCD, we can accommodate the spokesman (or demand valve"), a source of replacement air (also called "octopus") and content of a gauge.
• The application (DV) Valve provides breathable air to the diver through a spokesman. The DV Reduced the air pressure in response to match the ambient pressure. The diver breaths in and out through the DV, the expired air being expelled by a hose on the DV, producing bubbles characteristic associated with breathing underwater.
• The Octopus is a second DV to be used by a dive buddy in case of emergency. It is usually bright yellow for easy identification underwater.
• The assessment shows the contents of the diver how much air remains in the cylinder and is usually a round dial with a needle point appropriate level. Sometimes the contents of the gauges can be combined with other instruments in a console, which may include a depth gauge and / or a compass.
Computer
Almost all divers use a modern computer. The computer is worn on the wrist like a watch oversized and has many functions. The computer will tell you the diver's depth, how long he has been diving and how long it can stay under water without the need for decompression stops on the ascent. It also measures the speed of ascent to the surface (it is very important control what rising too quickly can cause decompression sickness, also known as "the bends"). The computer has other functions as calculating decompression and some can also be used for accelerated decompression using a mixture of respiratory gases, These are but advanced techniques and therefore does not beginners.
IMPORTANT NOTE
It is IMPERRATIVE all those contemplating undertakes a good dive training with a recognized training agency. None of the equipment mentioned in this section shall be used without instruction. With proper training, scuba diving is a fun, exciting, enjoyable pastime, but it can be very dangerous.
