Three eccentric butterfly valve introduction, use, material, advantages and disadvantages, maintenance and maintenance

Three eccentric butterfly valve is a common type of valve, the core component of the butterfly disc. This type of valve has many advantages and is widely used in many fields. This paper will introduce the use, material, advantages and disadvantages of the three eccentric butterfly valve, maintenance and the choice of Lyco valve.

One, three eccentric butterfly valve use

Three eccentric butterfly valves are widely used in industrial, chemical, municipal, HVAC, navigation and metallurgical industries. Specifically, it is mainly used for the turn-off and adjustment of fluid control. The three-eccentric butterfly valve has simple structure, flexible operation, large flow, long service life, and is not easy to leak. Therefore, it has been widely used in industrial pipeline systems of various fluid media.

Two, three eccentric butterfly valve material

Choosing the right material is essential to ensure the durability and performance of the three-eccentric butterfly valve. Depending on the application environment and media type, the three eccentric butterfly valve can be used in a variety of materials, such as carbon steel, stainless steel, alloy steel, aluminum alloy, ecological copper, etc. According to the field of use and temperature requirements of the valve, different materials can be selected.

Three, three eccentric butterfly valve advantages and disadvantages

Three eccentric butterfly valves have many advantages, including:

1. Compact structure, small size, space saving;

2. Flexible operation, labor-saving, easy installation and maintenance;

3. Low fluid resistance, wear resistance, long service life;

4. With fast switching and closing characteristics, it is not easy to leak and clog.

On the contrary, the shortcomings of the three-eccentric butterfly valve are mainly reflected in the following aspects:

1. When the valve is partially opened, vibration and noise may occur;

2. The rotation Angle is small, the effect is better in the straight pipe, but the effect is not good in the bend and branch pipe;

3. The small curvature radius makes the valve difficult to use in high pressure and high temperature environments.

Four, three eccentric butterfly valve maintenance

Routine maintenance and maintenance of the three-eccentric butterfly valve can extend its service life and performance, including:

1. Regular cleaning, lubrication and inspection, try to avoid dust, dirt and other particles into the valve;

2. After long-term disuse, the valve should be comprehensively inspected and tested to ensure its normal operation;

3. Replace the badly worn parts to ensure the normal operation of the three-eccentric butterfly valve;

4. If the valve is often not closed tightly, the sealing ring should be replaced.

Five, the choice of likv valve

likv Valve is one of the well-known valve manufacturers in China, providing high quality three eccentric butterfly valves and other valve products. It has many years of manufacturing and sales experience, with a professional manufacturing and sales team, the production process is strictly controlled, and the quality and performance of the products are fully guaranteed. At the same time, LYco also provides thoughtful after-sales service to meet customers’ requirements for products and services.

Summary: The three-eccentric butterfly valve is a valve product with excellent performance and strong durability, which has become an indispensable part of many industrial enterprises. This paper introduces the three-eccentric butterfly valve, analyzes its use, material, advantages and disadvantages, maintenance and the choice of Lyco valve. It is hoped that this paper can play a certain role in the selection and use of three-eccentric butterfly valves for valve users.
