압력조정기의 작동원리

(a) 압력 조정 valve가 고압실과 저아실의 통로를 막고 있다.

(b) 조정 handle을 돌려 diapharagm(격막)밀어 압력조정 valve를 열면 고압실의 gas가 저압실로 유입된다.

위의 (c)를 설명하는 animation

# Bourdon관 압력계(Bourdon tube pressure gage)

한쪽 끝이 막힌 C자형으로 굽힌 타원형 단면을 갖는 Bourdon tube 내에 압력유체가 유입되면 압력에 비례하여 Bourdon tube가 펴지게되고, Bourdon tube의 변형은 sector gear를 거쳐 지침을 회전시켜 작용압력을 지시한다.

Pressure regulator:

The pressure regulators enable the user to reduce the high pressure contained in the cylinder to a usable working pressure. There are several handling and set up procedures that are important to the overall operation of the pressure regulator. The pressure regulator on each tank shows two things:

Cylinder pressure (How much gas is in the cylinder)
Working or line pressure

Installing the regulators

Before installing the regulator crack the cylinder valve to clean out any dirt or dust.
Mount the regulator onto the cylinder.
- Ensure that the oxygen pressure regulator is on the oxygen tank.
Do Not over tighten regulator nut.
Before opening the cylinder valve ensure that the pressure regulator screws are released (turned out).
Never use oil or grease on the regulators.
- Frictional heat as a result of high pressures can cause oil to ignite and possibly cause an explosion.
