Precautions for using fluorine-lined gate valves

The development prospects of the fluorine-lined gate valve industry are very good, because when it is used, it brings more benefits to the enterprise, so it is favored by customers. In order to make everyone more familiar with it, next we will tell about the precautions for using the fluorine-lined gate valve. I hope it can help more people.

Today, there are still many people who do not understand some basic information about fluorine-lined gate valves, so as a manufacturer, we are also necessary to briefly explain, in fact, fluorine-lined gate valves are mainly used to control corrosive or highly corrosive media. The inner cavity surface of the valve is covered with various fluorine plastics. Suitable for different operating temperatures and fluid pipelines. It has the characteristics of high strength and good corrosion resistance. While it has many advantages, there are also many caveats. For example, it is recommended that you read the product instructions carefully before use. It must also be used within the pressure, temperature and medium range specified in the nameplate or manual. Fluorine-lined gate valves should also prevent excessive pipeline stress caused by temperature changes during use, minimize temperature changes, and add U-shaped expansion joints before and after the valve. Of course, it is also forbidden to use levers to open and close fluorine-lined valves. Observe the opening and closing indicating position and limiting device of the fluorine-lined valve.

In addition, we should pay attention to some media is unstable, easy to decompose, may cause valve damage or leakage, because you should take measures to eliminate or limit the factors that cause the decomposition of unstable media. In the selection of fluorine-lined gate valve should take into account the unstable and easily decompressed media may cause changes in working conditions, the selection of fluorine-lined gate valve with automatic pressure relief device should pay attention to the fluorine lined valve on the pipeline of toxic, flammable, explosive and highly corrosive media, and it is strictly prohibited to replace the packing with pressure. Although the fluorine-lined gate valve is designed with an upper sealing function, it is not recommended to replace the packing with pressure. For the pipeline with spontaneous combustion medium, measures should be taken to ensure that the ambient temperature and working temperature do not exceed the spontaneous combustion point of the medium to prevent the danger caused by direct sunlight or external open flame. During installation, attention should also be paid to the severe and long-term vibration of the pipeline, and measures should be taken to avoid damage. In the process of its use, the fluorine plastic sealing surface is soft, and the sealing surface is often damaged by medium crystallization and solid particles, resulting in seal leakage. Repair or replace the seal in time after discovery. Here is a regular manufacturer, want to order the product friends may wish to choose here. Believing won't let you down. The price here is reasonable and the quality is guaranteed. And there are many types of products, there is always one that is suitable for you. Welcome to buy.

After the introduction of the above content, we also have a further understanding of the precautions for using fluorine-lined gate valves. It will not feel strange when you see it again in the future, and it will not often cause problems in the process of use. Well, today's content said here, I believe it will bring more wonderful knowledge.
