Helium release valve

Helium Release Valve

A Helium Release Valve is a specialized piece of equipment used in the field of deep-sea diving and horology. It is primarily found in professional-grade diving watches, designed to release helium gas that may have been absorbed into the watch during deep-sea diving operations.

Function

During saturation diving or commercial diving, divers are exposed to a mixture of gases, including helium, under high pressure. The small helium molecules can penetrate the watch case, increasing the internal pressure. When the diver ascends and the pressure decreases, the helium trapped inside the watch needs to be safely released to prevent damage to the watch. This is where the helium release valve comes into play.

Design

The helium release valve is typically located on the side of the watch case. It is designed to open when the pressure difference between the inside and outside of the watch reaches a certain level, allowing the trapped helium to escape. The valve then automatically closes when the pressures are equalized.

Usage

While the helium release valve is a feature of many professional-grade diving watches, it is not necessary for most recreational divers. The valve is specifically designed for use in saturation diving or commercial diving where divers are exposed to high-pressure environments for extended periods.
