What is the production principle of sanitary stainless steel 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 sanitary stainless steel sight glass bottom plate as the valve body. Add a valve to the upper and lower liquid inlets to control the bottom plate. Install a sight glass level gauge on the sanitary stainless steel sight glass bottom plate, 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 sanitary stainless steel sight glass leaks or the sanitary stainless steel sight glass is damaged, the valve on the bottom plate can be closed first, so that the sanitary stainless steel sight glass can be replaced without stopping the machine, and the normal production can be ensured. Moreover, the personal safety of the operators and the safety of the working environment are also guaranteed.
What are the main uses and parameters of sanitary stainless steel sight glass?
sanitary stainless steel sight glass is used to observe the reaction and flow of liquid medium in the pipeline to ensure the normal progress of production. The mirror is manufactured according to hgj501 ~ 502-86 pressure vessel mirror standard, and the production can be arranged according to the needs of users; Product material: shell: carbon steel, stainless steel, lens material: tempered borosilicate glass, plexiglass, quartz glass, sealing material: 0.6-2.5mpa, working temperature: - 20-200 ℃; It mainly includes: zzhb straight through mirror (including zzhb-y impeller type and zzhb-b swing plate type) and zzhb-bl glass tube mirror.
What is the installation method of sanitary stainless steel sight glass?
1. Selection of installation location. sanitary stainless steel sight glass is installed at a certain point in the pipeline. It is used for employees to observe, so the selection of location is very important. The first is the location. If it is installed in a very biased position, it will take half a day for each observation, which may affect employees' enthusiasm and timeliness
2. Height selection. sanitary stainless steel sight glass is used for observation, mainly manual observation (a few are replaced by installing monitoring equipment). Therefore, the installation height of pipe mirror shall be subject to the convenient observation of personnel. It is too high, and the climbing tools must be borrowed every time, which is very inconvenient; If the position is too low, you may not be able to observe clearly
3. Sufficient light. Since it is observation, light is a crucial condition, and it can't be seen clearly in the dark. Therefore, sanitary stainless steel sight glass must be installed in the pipe with sufficient light, or specially equipped with lighting device
4. Installation of sanitary stainless steel sight glass lens. Ensure that the mirror base is flat and smooth, the sealing gasket between the lens and the mirror base is installed smoothly, and the sealing gasket is not damaged and does not stick grease. Before fastening the screws, make sure that the mirror base and cover are installed correctly, and then slowly tighten the screws diagonally
5. For flange or threaded sanitary stainless steel sight glass device, ensure that the sealing gasket is installed well before operation. If necessary, retighten the bolts. Ensure that the sealing gasket between the pipe and the pipe mirror is installed correctly, the connecting flange is not damaged, and adjust the connecting screw. Ensure not only that the accessories connected with the mirror lens are well sealed, but also that the mirror and the pipe are well sealed. And ensure that the pressure in the pipeline does not exceed the rated pressure
