The glass plate liquid level gauge is composed of upper and lower needle valves, intermediate indicating devices, etc. The glass plate liquid level gauge is composed of a glass plate liquid level gauge which is composed of an upper and lower needle valve and an intermediate indicating device, and the hand wheel control valve is screwed. Open and close, open the valve, the medium flows into the middle indicating device through the valve, and the liquid level can be clearly reflected through the glass plate within the effective light transmission range of the glass plate level gauge.
Second, the glass plate level gauge maintenance and precautions 1, in order to prevent the surface corrosion of the glass plate level gauge, the appearance should be kept clean and dry.
2. Use a liquid level gauge with a temperature higher than normal temperature. It is not advisable to open the valve immediately after installation. It should be preheated for 20-30 minutes. After the glass plate has a certain temperature, it can enter the medium. After using the glass plate level gauge for a period of time, the platen screws should be re-tightened. When tightening, the clamps should be clamped several times in the form of 1, 3, 5, 2, 4, 6...
3. When the needle valve is opened, it should be gradually opened to prevent the steel ball in the valve from being automatically sealed by the medium one-way pressure and affecting the correctness of the indicated liquid level. However, after the flow of the medium is stable, the valve should be fully opened to prevent accidental occurrence. The steel ball in the valve is blocked by the valve flap and affects the automatic closing of the valve.
4. In order to reduce the installation stress, the actual deviation between the center distance of the two flanges and the center distance of the two flanges of the container should be checked during installation. When the deviation is too large, it should be adjusted.
