The triple eccentric hard sealing butterfly valve, also known as the flap valve, is a kind of regulating valve with a simple structure. The butterfly valve can be used to control various types of air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. The flow of fluid mainly plays the role of cutting off and throttling on the pipeline. The butterfly valve opening and closing part is a disc-shaped butterfly plate, which rotates around its own axis in the valve body to achieve the purpose of opening and closing or adjustment.

As a component used to realize the on-off and flow control of the pipeline system, the triple eccentric hard sealing butterfly valve has been widely used in many fields such as petroleum, chemical industry, metallurgy and hydropower. In the butterfly valve technology that has been in public office, the sealing form mostly adopts the sealing structure, and the sealing material is mainly rubber. However, the continuous use of the rubber elastomer in the butterfly valve will cause tearing, abrasion, aging, perforation and even falling off, which will greatly affect the sealing performance of the butterfly valve. , In addition, special equipment should be used when repairing, which consumes a lot of heat and electricity, which is time-consuming and labor-intensive. Nowadays, the method of polymer composite material is gradually used to replace the traditional method, and the repair effect is better.

In terms of the appearance and structure of the triple eccentric hard sealing butterfly valve, the structure is simple and the components are less. In terms of volume, its volume is also relatively light. Such appearance structure and volume make it widely used in piping system. In order to make it work better, it needs to be regularly maintained during its continuous use, so how to do it?

The maintenance of the triple eccentric hard sealing butterfly valve is actually very simple, as long as the following work is done.

In daily use, the triple eccentric hard sealing butterfly valve should be kept clean, so that it is not only smoother and more efficient in use, but also looks relatively comfortable. When a failure occurs during use, the operation should be stopped in time, and the cause of the failure should be checked and properly solved. There are also certain requirements for the selection of the working environment. For example, due to the structural material, for some high temperature and high pressure environments, the work of the triple eccentric hard sealing butterfly valve will be affected, so it is better not to work in these environments. And in the process of use, the erosion of the sealing surface should be avoided as much as possible, which will accelerate the wear of the triple eccentric hard sealing butterfly valve.

As long as the maintenance of the above three eccentric hard sealing butterfly valve is done, its application will be relatively simple and the service life will be longer.
