nature : also known as receptacles counters or gas counters. Gas storage equipment. Closed tight, leak. Pressure and balance the supply and regulation role. Usually divided into storage pressure gauge pressure of not more than 4.9 kPa (500 mm water column) gas pressure gas storage cabinets and pressure gauge pressure of about 0.5 MPa (5 atm) of the high pressure gas two counters. High-pressure gas counters generally spherical (a cylindrical shape), the structure of low-pressure air over the counter tight, no insulation, but the compressed gases great energy consumption. Low-pressure gas tank is divided into immersion water tank enclosed cabinets and wet gas was used as a seal of dry gas counters. Dry gas counters than the wet gas counters with greater volume, and do not need special insulation device. Wet gas counters by four major components : (1) water tank is installed water fountain; (2) dish, which is below the top spherical opening containers; (3) Weight surge generally attached to the bottom of the dish, a drawer used to regulate the gas pressure level; (4) Telescopic wooden cabinet, located between the sink and dish, the opening of two cones. Roof and telescopic gas storage enclosure with the change movements. In large gas counters, the enclosure of the middle stretch and have one of the two.
