regulator

Abstract

This product is a regulator for a self-contained underwater breathing apparatus that is secured to the forearm with a band or similar device. This product is a regulator that can mount up to two extremely small metal cylinders, each with a gas capacity of 0.1L and a pressure of 150 atmospheres, as shown in the reference diagram. The female threads at the top openings of the metal cylinders are screwed into the male threads on the bottom of this product and sealed airtight with O-rings. Then, the bolt at the filling port located between the breathing port on the front left and the pressure meter on the front right of this product can be removed, and the metal cylinders can be pressurized and filled with gas using a pump. The high-pressure gas in the metal cylinder can be supplied to the breathing port by loosening the throttle on the main valve on the top surface. The circle in the center of the left side is a rubber pressure relief valve, and by pressing the center of the pressure relief valve, eight small holes arranged around the outer circumference are opened, allowing water and gas in the regulator to be discharged through these holes. The circular part that appears on the right center of the back is a rubber valve that can push gas and water out from the inside. After the diver has pushed out the water around the breathing port, they can hold the rubber breathing port to their lips and inhale gas, and that amount of gas will be supplied from the metal cylinder to the regulator.
