HG5 glass tube type level gauge

HG5 glass tube type level gauge is used in chemical, oil and other industrial cryogenic equipment level indication. HG5 glass tube equipped with a level gauge on the instrument's upper and lower valve product structure flange joints, connectors Unicom and container structure, through a direct indication of the glass container Bush level, "dips" with a heating or cooling system. When the device is available for steam heating, cooling circulating water available, so you can adjust the flow properties, dips over size ZG1 / 4 '' inside thread. In the upper and lower valve that has the ball, when the glass damage because of an accident, the ball under pressure vessel, self-sealing, to prevent the liquid in the container continue drain. The upper end of the instrument is equipped with a needle valve blocking screws for deflation purposes, the lower end of the needle valve is also provided with blocking screws. For venting, sampling, sewage and cleaning. The main technical parameters 1. Working temperature: 0 ~ 200 ℃ 2. Nominal diameter: 20mm / 25mm 3. Pressure rating (Mpa): ≤1.6 4. needle valve automatically closes pressure (MPa): ≥0.2 6. glass The heat-resistant CML temperature difference is 180 ℃ 7. Main Material: Q235-A (carbon steel) 1Cr18Ni9Ti (stainless steel) Nominal length: L (mm) 500 600 800 1000 1100 1200 1400 1700 2000 If you have special requirements can be negotiated when ordering. HG5 glass tube level gauge installation, use and maintenance 1, both the container and the flange face connected to the instrument should ensure that in the same vertical plane, or after the meter is installed so that the valve deflection, resulting in broken glass. 2, in order to ensure the pieces move dense than planned action, medium pressure inside the container should be greater than 0.2MPa, when you open the top and bottom valve stem revolutions withdraw not less than 4 turn (so that the ball closed door warrant encounter stem top.) 3, the use of the instrument be checked regularly. Cleared glass outer wall of dirt, so that the liquid clear display. Needle valve nut washer guard then tighten the screw rod screw clamp protective cover glass washer nut screw bushing
