Product Features
Mirrors are used in industrial production equipment such as petroleum, chemical, synthetic fiber, medicine, and food. They can observe the flow and reaction of liquids, gases, steam, and other media at any time, and are an indispensable accessory to ensure normal production.
Glass tube sight glass, also known as a viewing cup, has a visible part that is a glass tube. The equipment is easy to install, has a low cost, and can be used in various low-pressure environments.
The glass tube sight cup consists of a connecting flange, a connecting conduit, a glass tube, a fixed flange, an extended bolt, and a sealing gasket. The fixed flange of the glass tube clamps the glass tube and is fixed with an extended bolt. The pipeline connection flange is connected to the same connecting conduit, thus forming a complete glass tube sight cup.

2. Mirror lens installation: Ensure that the mirror base is flat and smooth, the sealing gasket between the lens and the mirror base is installed flat, the sealing gasket is not damaged, and does not stick to grease. Before tightening the screws, make sure that the mirror base and cover are installed correctly, and then slowly tighten the screws.
3. Before operating the hinged or threaded mirror device, it is necessary to ensure that the sealing gasket is properly installed. If necessary, the bolts can be re tightened. Ensure that the sealing gasket between the sight hole and the mirror hole is installed correctly, the connecting flange is not damaged, and adjust the connecting screws. It is not only necessary to ensure that the components connected to the mirror lens are well sealed, but also to ensure that the sealing between the mirror and the welding flange is good, and to ensure that the pressure inside the container does not exceed the rated pressure.
4. After installation, there should be no additional pressure on the mirror, otherwise it will cause uneven force on the mirror, leading to the breakage of the mirror glass.
