不锈钢304方形直通视镜四通法兰视镜水流观察指示器DN100可用于温度高,腐蚀性强、易中毒、危险性较大,易结晶的化工塔器中,以保证其安全生产。
不锈钢304方形直通视镜主要由视镜底板、视镜玻璃、阀门组件等组成。本类阀门在管道中一般应当水平安装。

尿素生产过程中,在带视镜的中低压塔器内,由于工作温度高,液体腐蚀性强的特点,容易造成液面计视镜玻璃损坏,视镜底板变形,而且在安装视镜玻璃过程中,有时因受力不均匀,易造成视镜玻璃破裂。如果没有及时发现,开车后必然发生泄漏,这时就必须全系统停车进行热洗更换。这样不但给系统长周期安全运行带来困难,而且严重影响尿素生产的效率。

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.



不锈钢304方形直通视镜

  根据尿素生产过程中“液体受温度影响易结晶"这一特点,结合各类截止阀,保温阀使用特点,经过长期的观察、摸索和思考,设计出利用视镜底板为阀体,在底板上、下进液处各加一阀门进行控制,在视镜底板上安装视镜玻璃液位计,周围通保温蒸汽保温,以防止液体降温结晶形成假液位。视镜底板焊接到塔类容器上,利用塔体的热量提高视镜底板的温度,进一步防止液体结晶。如果视镜泄漏或视镜玻璃损坏,可先关闭底板上的阀门,这样既起到不停车就可更换视镜玻璃的目的,又能够保证生产的正常进行,而且操作人员的人身安全及工作环境安全也得到了保障。经肥城市化肥厂在尿素预蒸馏塔上试验,一次获得成功,可控式保温视镜领域的空白。

Stainless steel 304 square through sight glass

   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.

不锈钢304方形直通视镜有以下结构特点:

⑴ 采用J44W-220R DN15高压截止阀形式,锥面密封,聚四氟乙烯填料密封。
⑵ 阀盖与阀体有螺栓连接,拆装方便。
⑶ 阀瓣与阀杆为整体结构,阀体内腔介质流道通畅,防止假液位。
⑷ 整体式阀体,双阀杆结构,外型布局合理。
⑸ 阀体可通保温蒸汽,作为介质保温,防止液体结晶。

⑹ 阀体与塔类容器焊接,提高阀体温度,二次防止液体结晶。

The stainless steel 304 square straight-through sight glass has the following structural characteristics:

⑴ It adopts J44W-220R DN15 high pressure stop valve form, conical surface seal, PTFE packing seal.

⑵ The valve cover and the valve body are connected by bolts, which is convenient for disassembly and assembly.

⑶ The valve clack and the valve stem are an integral structure, and the medium flow passage in the valve body is unobstructed to prevent false liquid level.

⑷ Integral valve body, double valve stem structure, reasonable appearance layout.

⑸ The valve body can pass through insulation steam, which is used as a medium for insulation to prevent liquid crystallization.

⑹ The valve body is welded to the tower container to increase the temperature of the valve body and prevent liquid crystallization for the second time.
