Gradually, the sky, which had been covered by night, began to dim.The morning stars gradually become pale, in the light of the light, timid they finally retreated.As the morning star disappeared, the shy sun threw out a few brilliant rays of gold.I watched intently.I saw the fiery red sun slowly.Rising from the east, spreading golden light in all directions
Direct vision mirror is widely used in important accessories of pipeline and equipment.Can be used in high temperature, corrosive, toxic, dangerous, easy to crystallize chemical tower, to ensure its safety in production.

According to "liquid in urea production process affected by temperature easily crystallized," this one characteristic, combining with all kinds of cut-off valve, insulation valves use characteristic, through long-term observation, the exploration and thinking, design the use of sight glass base plate for the body, under the floor, one valve to control, is put into the fluid in the sight glass base plate installed on the lens glass level gauge, around the heating steam heat,To prevent the liquid from cooling crystallization to form a false level.The bottom plate of the mirror is welded to the tower container, and the heat of the tower body is used to increase the temperature of the bottom plate of the mirror to further prevent liquid crystallization.If the mirror leaks or the mirror glass is damaged, the valve on the bottom plate can be closed first, so as not only to replace the mirror glass without stopping, but also to ensure the normal production, and the personal safety of the operator and the safety of the working environment are also guaranteed.The experiment on urea pre-distillation tower in Feicheng Chemical fertilizer Plant was successful once, which filled the blank in the field of controllable thermal insulation mirror
