Glass level gauge products are widely used and suitable for transparent or relatively transparent media that can corrode carbon steel or stainless steel, such as water, liquid ammonia, gasoline, liquefied gas, room temperature alkali solution, dilute acid, various hydrocarbons, oil products, and various salt reducing solutions. It can be used to directly indicate the liquid level height in sealed containers, with the advantages of simple structure, intuitive reliability, and durability. However, the medium in the container must not corrode steel, steel paper, and graphite pressure rings. The UG-2 glass plate level gauge is produced according to the original Ministry of Chemical Industry HG5-1364~1370-80 standards and is suitable for directly indicating the liquid level of various media in towers, tanks, tanks, boxes, and other containers. Safety steel balls are installed inside the upper and lower valves of the instrument. When the glass is accidentally damaged, the steel balls can automatically close the liquid flow channel under the pressure inside the container to prevent the liquid level from continuing to flow out. Main technical parameters 1. Measurement range (installation center distance L mm): 300, 500, 800, 1100, 1400, 1700; 2. Nominal pressure: 2.5 4.0 6.4, 10.0, 16.0MPa or high pressure 3. Working temperature:- 20~380℃ 4. Automatic closing pressure of steel ball: ≥ 0.2 MPa； 7. Wetting material: carbon steel or 1Cr18Ni9Ti 8. Connection flange: JB/T82.2-94, DN20 PN4.0 raised face flange; 9. If other flange standards are used, please indicate them when placing an order. Use installation: When the instrument installation is completed and put into operation, slowly open the valve and turn the valve handwheel once, then hold it for about 5 minutes, and then slowly open the valve. When repairing and assembling glass panels, pay close attention to the uneven force on the glass and its breakage when tightening the bolts. The bolts must be tightened strictly in a cross pattern, using a kilogram wrench to tighten the glass panel multiple times.
