Generally speaking, a diving regulator is a device that controls the pressure of breathing gas for a diver. It is used to reduce the pressure of pressurized breath gas to ambient and deliver it to the diver. A dive regulator can also control other gas pressures. You can find out more about this regulator by reading the following. Here are some types regulators:
Stage I
Attached to a diver’s air tank, the first stage is a dive regulator. It regulates the air pressure before it enters into the diver’s air hose. The second stage includes a mouthpiece with purge valve. This valve delivers air directly to the diver's nose and removes waste gas when needed. Both stages work together to provide safe and comfortable diving. What are their differences, you ask?

The first stage is composed of two parts and the second of a plastic material. Both stages are mechanically operated, and they use a valve to control the amount of gas released. The first stage is responsible for providing air for the first stage. The second stage is intended for secondary purposes. A connector connects to the first stage and the rebreather. This connector allows the diver, who is able to share air with his rebreather underwater, to be able to comfortably inhale.
Mouthpiece
A mouthpiece for your diving regulator is a necessary part of the diving apparatus. It is a straight-edged oval tube with a curving flange that fits between the teeth and your lips. While you breath, the mouthpiece seals against your inner ear. You can bite the tabs on either end of the mouthpiece to hold it in place. Mouthpieces can be easily replaced and are cheap so make sure you choose the right one for your mouth.
High-quality materials can be used to make a mouthpiece for your regulator. They are durable enough to withstand long-term storage and frequent use. Its quality will not only save you from headaches, but it will also save you money on replacement parts. Here's a guide for regulators and mouthpieces. Also, you'll learn about maintenance of your dive regulator and how to care. To learn more about how to maintain your regulator's mouthpiece, please read Do you pick-up rubbish while diving?
Exhaust Valve
The diver controls the flow of air through the regulator by manually depressing a diaphragm or lever. The exhaust valve is one-way and allows exhaled air to exit the regulator. The regulator is kept dry by keeping the exhaust valve closed when the diver stops exhaling. The regulator's second stage is an additional air source. This can be a BCD inflation/deflation tube.
In one embodiment, the diver’s regulator and mouthpiece are in fluid communication. The diver inhales using mouthpiece 26 a, and then exhales through regulator valve 24 d.
First stage: Diaphragmtype
A dive regulator's diaphragm first stage is a lever-type device that sits inside an air chamber. The diaphragm presses in water pressure to activate it. This creates a balance between the pressure of water and the air 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 can be more reliable and simpler, but they also have some disadvantages. Piston-type regulators are more susceptible to freezing conditions, as well as dirty water. Clear water is preferred for recreational diving.
