A regulator for diving is simply a device that lowers the pressure in the diver's breathing gas. It reduces the pressure of compressed breathing gas to an ambient level and delivers it directly to the diver. Diver regulators can also be used for controlling other gas pressures. Continue reading for more information. Below is a list of types of regulators.
First stage
The first stage of a dive regulator is attached to a diver's air tank. The regulator regulates air pressure and then releases it into the diver's 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 of these stages are interconnected to ensure safe and comfortable diving. What are their differences, you ask? Continue reading for more information.
The first stage is composed of two parts and the second of a plastic material. Both stages can be operated mechanically and use a valve for controlling the release of gas. The first stage supplies the air for the initial stage while the second stage is for secondary use. The first stage is connected to the rebreather by means of a connector. 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 rectangular tube with a flattened flange and fits between your teeth. It seals against the inside your mouth and allows you to breathe. You must keep the mouthpiece in its place by biting down on the tabs. Mouthpieces are easy to replace and inexpensive so be sure to pick one that suits your needs.
To withstand repeated use and long-term storage, a mouthpiece can be made from high-quality materials. The quality of your mouthpiece will not only save you headaches but also help you save money on replacing parts. Here's an overview of 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
By manually depressing a lever or dial, the diver controls air flow through the regulator. The exhaust valve allows air to exit through the regulator, which is only one way. This valve closes when the diver is not inhaling and prevents water entering the regulator. 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
A diaphragm-type dive regulator's first stage has two parts. It has a lever that is located within the air chamber, and a diaphragm which presses in when water pressure rises. This balances the air pressure and water inside. Because it prevents water from coming into contact with its internal mechanism, this type of regulator is often used by scuba divers.
Two basic designs are available for diving regulators: piston-type or diaphragm-type. Both types sense water at ambient pressure, and deliver air at pressures similar to those around them. Piston-type regulators can be more reliable and simpler, but they also have some disadvantages. Piston-type regulators may be susceptible to freezing conditions or dirty water. However, most recreational diving occurs in clear water.
