Product Description

250 Degree SS304 High Temperature Boiler Sight Glass Level Indicator

Product Description

Glass plate level gauge is divided into three kinds: Transparent type, reflection type and sight glass type. The level gauge is mainly composed by level gauge’s body, upper valve (gas valve), lower valve (liquid valve), drain valve, insurance steel ball and so on. When the glass plate have some cracks or be damaged, the insurance steel ball will automatically stop the side valve of gas and liquid to avoid or reduce flowing. So the worker can cut off the bottom valve to handle it. This series product is stable, sealed and reliable, simple installation, which is ideal instrument for detecting for liquid level in all kinds of containers with middle or low pressure.Connecting the upper and lower flanges of this level gauge with the upper and lower flanges of the container to form a permeator, then the height of liquid can be directly seen.

The glass plate type liquid level meter is designed based on the principle of the communicator. The liquid passage formed by the glass plate and the liquid level gauge body is connected to the measured container through a flange or a taper pipe thread to form a communicator, which is observed through the glass plate. The liquid level is the same as the liquid level in the container, that is, the liquid level.

The needle valve at both ends of the level gauge not only functions as a stop valve, but also has the function of a check valve in the internal steel ball. When the liquid level gauge accidentally breaks and leaks, the steel ball can automatically close the liquid passage under the action of the medium pressure. To prevent the large outflow of liquid for safety protection. The level gauge can change the material of the part or add some ancillary parts to achieve anti-corrosion, thermal insulation, anti-frost, lighting and other functions. Widely used in petroleum, chemical industry, electric power, metallurgy, medicine and other fields.

Tips for installation

1. During installation, in order to ensure the function of automatic sealing, the liquid in the container must have a certain pressure, at least more than 0.2MPa. When the upper and lower valves are opened, the valve stem quitting cannot be less than four turns. When the steel ball seals the door, it does not hit the top of the valve stem to avoid damage.

2. In the process of transportation and unpacking, we must be careful not to encounter something harder to avoid breaking the glass plate.

3. Also pay attention to the specifications and models, cannot install the wrong gauge level gauge, some media on the leveler is limited, such as some of the glass or steel plate corrosive media cannot be used.

4. Other maintenance clean, wash and install with the glass tube level gauge is similar

 
 

Inspection method of reflex level gauge

1. Remove the bolts and nuts on the glass plate level gauge, and remove the gland, gasket, glass plate and mica flakes in order (the level gauge for measuring alkaline medium only has mica flakes, and the others do not have mica flakes).
2. Clean the dust and oil stains on the level gauge;
3. Remove the rust on the level gauge;
4. Remove the residue of the sealing gasket in the sealing window of the level gauge, taking care not to damage the sealing surface;
5. Trim the sealing surface to make the surface roughness meet the requirements.
6. Replace with new spare parts
7. Install one piece of metal graphite gasket, one piece of mica sheet in order (the level gauge for measuring alkaline medium only has mica sheet, and the others do not have mica sheet), one glass plate and one piece of buffer metal graphite gasket And gland;
8. Fasten with fastening bolts. The fastening sequence is shown in the figure below. When fastening, the bolts must be gradually and evenly applied in sequence, using 15N. Tighten in increments of M torque, and the rear sealing torque is about 100N. M.
9. Replace with a new blowdown valve (if it is not damaged, it can be replaced).
10. Water pressure test (pressure test pump) and appearance inspection, the water pressure test is carried out at 1.5 times the working pressure, and no pressure drop within 5 minutes is qualified;
11. Dry the water of the level gauge and visually inspect the appearance.
