What should I pay attention to when installing the straight-through float sight glass?
Straight-through floating ball sight glass is one of the main accessories on industrial pipeline equipment. In the pipelines of petroleum, chemical, pharmaceutical, food and other industrial production equipment, the flow and reaction of liquid, gas, steam and other media in the pipeline can be observed at any time until Monitor production to avoid accidents during production. At present, the commonly used pipeline through-view mirror valve body in China is fully welded, which is too large and expensive, especially for stainless steel. It only has a peek into the fluid in the pipeline! The size of the straight-through floating ball sight glass is small, which is cheaper compared to the price. In this era of low profit, it saves a lot of user companies.
Straight-through floating ball sight glass includes fluid pipes and sight-glass pipes that pass through each other. The sight glass pipe of the product is provided with sight glasses at both ends. The sight glass pipe of the product is provided with a rotatable impeller. A transmission rod is fixed at the center of the impeller, and a rotating disk is fixed at the other end of the driving rod of the product. The position of the rotating disk of the product is higher than the highest point of the fluid pipeline.
The straight-through floating ball sight glass consists of glass sight glass, observation pipe, and water inlet and outlet pipes. The observation pipe is connected to the water inlet pipe and the water outlet pipe by welding. The observation pipe is provided with a floating ball and a wire mesh. The wire mesh prevents the floating ball. As the medium flows out to observe the pipeline, the density of the float is lower than the density of the liquid transported by the pipeline. When there is medium flowing in the pipeline, the floating ball will float on the medium and shake with the intensity of the medium flow, so that you can directly observe the medium flowing in the pipeline. Often used in petroleum, chemical, chemical fiber, pharmaceutical and other production pipelines.
Matters needing attention when installing and using:
⑴ Strengthen the management of production process indicators. Strictly control the outlet temperature of the pre-distillation tower at 120 ° C and a pressure of 1.765MPa, and the outlet temperature of a suction tower ≤ 46 ° C and a pressure of 1.765MPa to prevent over-temperature and over-pressure.
⑵ Improve the material of sight glass gasket. Use corrosion-resistant, aging-resistant, high-temperature-resistant PTFE board. When installing the straight-through floating ball sight glass , the sealing surface and gasket should be visually inspected. There should be no defects such as radial grooves and scratches. The installation is smooth, the position is accurate, there is no skew or center offset, and the contact is good, which meets the requirements for use.
