Glass Tube Sight Glass Product Overview
Jun 27, 2024| Product Overview:
Glass tube sight glass is one of the main accessories on the sanitary pipeline device, its most important feature is to have a 360 ° observation surface, in medicine, food and other sanitary production equipment in the pipeline, can be observed from all directions at any time to the pipeline in the liquid, gas, steam and other media flow and reaction, play a role in monitoring the production, to avoid accidents in the production process. Pressure bottom, generally applicable to low-pressure piping, nominal pressure of 6 kg / cm of glass tube in the glass tube sight glass tube no official products, such as the choice of trial production shall be carried out.
Pipeline sight glass is one of the main accessories on the industrial pipeline device, through which you can always observe the pipeline in the liquid, gas, steam and other media flow reaction, monitoring production, to avoid accidents in the production process. Often used in petroleum, chemical, chemical fiber, pharmaceutical and other production pipelines.
It has a small installation size, and small driving torque, easy and rapid operation, and also has a good flow adjustment function and close sealing characteristics at the same time, the sight glass in the large and medium caliber, medium and low pressure in the use of the field, it is the dominant form of sight glass.
Usage:
Sight glass can be used in high temperature, corrosive, easy to poison, dangerous, easy to crystallize the chemical tower to ensure its safe production.
Structure:
Sight glass is mainly composed of sight glass base plate, sight glass, valve assembly and so on.
Usage
(1) Cleaning treatment. Before use, you can use the appropriate amount of alcohol cotton to wipe lightly on its surface, note: do not use acid-containing liquids for cleaning, so as not to corrode the outer surface of the glass.
(2) To correctly select the gasket. Ambient operating temperature of 280 degrees or less, with asbestos gasket or PTFE gasket can be, when the ambient operating temperature exceeds 500 ℃, it is recommended to choose graphite gasket. Note: The thicker the glass, so the thickness of the selected gasket should be increased accordingly.
(3) Uniform force. Installation should not be too strong, too large, it is recommended to evenly force the diagonal locking screws.
(4) Regular inspection. Sight glass in the installation is completed, but also must do a good job of regular inspection, especially in the liquid environment containing acid, alkali, it is necessary to do a good job of regular inspection of the surface of the glass by the degree of corrosion, in order to ensure the safety of first-line operators.
1, sight glass installation Welding flange must be clean and undamaged, operated by professionals.
2, sight glass lens installation Be sure that the sight glass seat is smooth and flat, the lens and the sight glass seat between the gasket installation is smooth, no damage to the gasket and does not stick to the grease. Before tightening the screws, make sure that the sight glass seat and cover are installed correctly, and then slowly tighten the screws.
3. Make sure the gasket is installed properly before working on articulated or threaded sight glass units. If necessary, retighten the bolts. Be sure that the gasket between the sight hole and the sight glass hole is installed correctly, the connecting flange is not damaged, and adjust the connecting screws. Be sure that not only the elements connected with the sight glass lens sealing is good, but also be sure that the seal between the sight glass and welding flange are good, and make sure that the pressure in the container does not exceed the rated pressure.
4, the installation can not have other additional pressure on the sight glass, otherwise it will cause the sight glass uneven force, resulting in sight 304, SUS304L, SUS316, SUS316L), fluorine lining, plastic (PP, PVC, etc.).
5,Sight glass material: soda-lime glass, borosilicate glass, quartz glass.
6,Operating temperature:
The maximum permissible temperature of soda-lime glass is 150℃, and the range of rapid change of temperature is 120℃ to 20℃.
The maximum permissible temperature of borosilicate glass is 280℃, and the range of rapid change of temperature is 230℃ to 20℃.
The maximum permissible temperature of quartz glass is 800℃, and the range of rapid change of temperature is 550℃ to 20℃.
7,Operating pressure: soda-lime glass: 0.6Mpa.
8,Borosilicate glass: 0.6~1.0Mpa.
9,Quartz glass: 0.6~2.5Mpa.
10,Material of sealing ring: PTFE, oil-resistant asbestos, nitrile rubber, etc.
