Chinese Lug Type Butterfly Valve: Compact and High Performing

I. Overview of Lug-type Butterfly Valve

1). Definition and Structure
The Lug-type butterfly valve is a valve that is opened and closed by rotating the butterfly plate. Its unique lug-type connection structure makes the valve have high strength and stability while maintaining a compact volume. The main components of the lug-type butterfly valve include valve body, butterfly plate, valve stem, lug connector and seal, etc.

2). Working Principle
The working principle of the lug-type butterfly valve is relatively simple: when the valve needs to be opened or closed, the drive device (such as handwheel, electric actuator, etc.) will drive the valve stem to rotate, and the valve stem and the butterfly plate are connected through the lug connector to realize the rotation of the butterfly plate. The rotation angle of the butterfly plate is proportional to the flow area of ​​the medium. By adjusting the opening angle of the butterfly plate, the flow rate of the medium can be accurately controlled.

II. Features of Lug-type Butterfly Valve

1). Compact Structure
The design of the lug-type butterfly valve makes its structure more compact, light weight, easy to install and maintain, and especially suitable for occasions with limited space.

2). Small flow resistance

Due to the smooth change of the flow channel when the butterfly plate rotates, the lug-type butterfly valve has a small flow resistance and can reduce the pressure loss of the system.

3). Flexible operation

The lug connection structure of the lug-type butterfly valve makes the butterfly plate rotate more flexibly, with short opening and closing time and fast response speed.

4). Good sealing performance

Using high-performance sealing materials, the lug-type butterfly valve can maintain good sealing performance under various temperature and pressure conditions.

5). Easy maintenance

The lug-type butterfly valve is easy to disassemble and maintain, without complex tools and equipment, which reduces maintenance costs.

III. Application of lug-type butterfly valve in industry

1. Flow control

Lug-type butterfly valves are widely used in flow control of various media, such as water, steam, air, petroleum, chemical products, etc.

2. Pipeline switching

In a multi-pipeline system, the lug-type butterfly valve can be used for medium switching to achieve medium distribution between different pipelines.

3. Valve isolation

When the pipeline needs to be isolated for maintenance or overhaul, the lug-type butterfly valve can quickly cut off the flow of the medium.

4. Adjusting the medium

Lug-type butterfly valves are suitable for occasions where the medium needs to be adjusted, such as adjusting temperature, pressure, etc.

     Lug-type butterfly valves butterfly-valve have occupied a place in the industrial valve market with their unique structural design, compact size and excellent performance. Its wide application not only improves the efficiency and safety of industrial processes, but also provides more possibilities for the design and maintenance of pipeline systems. With the continuous advancement of technology, lug-type butterfly valves will continue to be optimized to meet more diverse industrial needs and become an important choice in the field of industrial pipeline control.
