A diving regulator, in general, is a device that regulates the pressure of breathing gas for divers. A regulator typically reduces pressure in the breathing gas and delivers it to a diver. A dive regulator can also control other gas pressures. Continue reading for more information. Here are some types regulators:
First stage
Attached directly to the air tank of a diver, this is the first part of a dive regulator. It regulates the air pressure before it enters into the diver’s air hose. The second stage is composed of a purge valve and a mouthpiece. It delivers air directly into the diver's mouth, and removes any waste gases as necessary. These two stages can be used together to ensure safe and comfortable diving. What are the differences between them? Continue reading to learn more.
The first stage is composed of two parts and the second of a plastic material. Both stages are mechanically controlled, and each stage has a control valve to regulate the amount gas released. The first stage provides the air for the first stage, while the second is designed for secondary use. A connector connects the first stage to the rebreather. This connector allows the diver's air to be shared with the rebreather.
Mouthpiece
The mouthpiece of your diving regulator is an essential part of your apparatus. It is a flattened oval tube with a curved flange that fits between your teeth and lips. While you breath, the mouthpiece seals against your inner ear. To keep the mouthpiece in place, you must bite down on each tab. Mouthpieces can be easily replaced and are cheap so make sure you choose the right one for your mouth.
You can make your mouthpiece from high-quality materials for long-term storage or frequent use. The quality of your mouthpiece will not only save you headaches but also help you save money on replacing parts. Here is a guide on regulators and mouthpieces. Learn more about maintaining your dive regulator, and how to take care of it. You can also read our article How to clean your regulator's mouthpiece.
Exhaust Valve
By manually depressing a lever or dial, the diver controls air flow through the regulator. Exhaled air exits the regulator through the exhaust valve, which is one-way. The regulator is kept dry by keeping the exhaust valve closed when the diver stops exhaling. The second stage of regulator can be used as an air source. It could be a BCD inflation/deflation hose.
In one embodiment, the diver's mouthpiece and regulator are in fluid communication with one another. The diver inhales 26 a through mouthpiece 26 and then breathes through the repositioned exhaust pipe 24 d.
First stage of Diaphragm-type
The diaphragm, or first stage, of a dive controller is made up of two parts. A lever sits within the chamber and a diaphragm. This diaphragm pushes in when there is more water pressure. This allows for a balance between the water and air pressure inside. This regulator prevents water from getting in contact with the internal mechanism. It is commonly used by divers.
Two basic designs are available for diving regulators: piston-type or diaphragm-type. Both types detect water at ambient pressure and provide air at a pressure comparable to the surrounding area. Piston-type regulators are more reliable and simple, but they have their disadvantages. Piston-type regulators may be susceptible to freezing conditions or dirty water. Clear water is the best environment for recreational diving.
