尿素生產過程中，在帶視鏡的中低壓塔器內，由于工作溫度高，液體腐蝕性強的特點，容易造成液面計視鏡玻璃損壞，視鏡底板變形，而且在安裝視鏡玻璃過程中，有時因受力不均勻，易造成視鏡玻璃破裂。如果沒有及時發現，開車后必然發生泄漏，這時就必須全系統停車進行熱洗更換。這樣不但給系統長周期安全運行帶來困難，而且嚴重影響尿素生產的效率。

Stainless steel 304 square straight-through sight glass four-way flange sight glass water flow observation indicator DN100 can be used in chemical towers with high temperature, strong corrosiveness, easy poisoning, greater danger, and easy crystallization to ensure safe production.

Stainless steel 304 square straight-through sight glass is mainly composed of sight glass bottom plate, sight glass, valve components and so on. This type of valve should generally be installed horizontally in the pipeline.

In the process of urea production, in the medium and low pressure tower with sight glass, due to the high working temperature and strong corrosiveness of the liquid, it is easy to cause damage to the sight glass of the liquid level meter, deformation of the sight glass bottom plate, and the process of installing the sight glass. In, sometimes due to uneven force, it is easy to cause the sight glass to break. If it is not found in time, leakage will inevitably occur after driving, and then the entire system must be shut down for hot wash replacement. This not only brings difficulties to the long-term safe operation of the system, but also seriously affects the efficiency of urea production.

 根據尿素生產過程中“液體受溫度影響易結晶"這一特點，結合各類截止閥，保溫閥使用特點，經過長期的觀察、摸索和思考，設計出利用視鏡底板為閥體，在底板上、下進液處各加一閥門進行控制，在視鏡底板上安裝視鏡玻璃液位計，周圍通保溫蒸汽保溫，以防止液體降溫結晶形成假液位。視鏡底板焊接到塔類容器上，利用塔體的熱量提高視鏡底板的溫度，進一步防止液體結晶。如果視鏡泄漏或視鏡玻璃損壞，可先關閉底板上的閥門，這樣既起到不停車就可更換視鏡玻璃的目的，又能夠保證生產的正常進行，而且操作人員的人身安全及工作環境安全也得到了保障。經肥城市化肥廠在尿素預蒸餾塔上試驗，一次獲得成功，可控式保溫視鏡領域的空白。

According to the characteristic of "liquid is easy to crystallize under the influence of temperature" in the urea production process, combined with the characteristics of various shut-off valves and heat preservation valves, after long-term observation, exploration and thinking, the design uses the bottom plate of the sight glass as the valve body. , Add a valve to the lower liquid inlet to control, install a sight glass level gauge on the bottom plate of the sight glass, and heat the surrounding steam to prevent the liquid from cooling and crystallizing to form a false liquid level. The bottom plate of the sight glass 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 sight glass to further prevent liquid crystallization. If the sight glass leaks or the sight glass is damaged, the valve on the bottom plate can be closed first. This not only serves the purpose of replacing the sight glass without stopping the vehicle, but also ensures the normal production and the personal safety and working environment of the operators. Safety is also guaranteed. After the Feicheng Fertilizer Plant tested on the urea pre-distillation tower, it was successful once, and it was a blank in the field of controllable heat preservation sight glasses.
