Product Description

Definition

The Lug Butterfly Valve is a type of butterfly valve. It is connected to the pipe flange by a lug structure on the valve body and can be easily installed and removed without disassembling the pipe system, the valve disc of which controls the flow of fluid by rotation in the pipe.

Working principle

When the valve is opened, the driving device drives the stem to rotate, and the disc rotates with it. The disc gradually rotates from a closed position perpendicular to the pipe to a fully open position parallel to the pipe, allowing fluid to flow smoothly through the valve. In the closing process, the disc rotates in reverse and gradually returns to the vertical position, and the sealing material on the edge of the disc is closely fitted with the valve body to cut off the fluid channel and achieve seal. The flow control of the valve is achieved by the Angle of rotation of the valve disc, the greater the rotation Angle, the larger the flow area, the greater the flow rate.

Performance characteristics

Ease of installation: The lug structure of the lug butterfly valve makes it unnecessary to completely disassemble the pipe during installation and disassembly, only the bolts on the lug need to be loosened. This makes it easy to replace valves or perform maintenance in an already operating piping system, greatly reducing downtime and effort.

Good sealing performance: the sealing material on the edge of the disc can provide a better sealing effect. Especially under low and medium pressure conditions, the sealing performance can meet the requirements of most application scenarios. However, under high pressure conditions, its sealing performance may be affected to some extent.

Good flow characteristics: the flow characteristics of the butterfly valve are approximately equal to the percentage characteristics. In the opening process, with the increase of the rotation Angle of the valve disc, the flow rate gradually increases, and the flow rate changes more evenly. It has large flow capacity and small fluid resistance when fully opened, which can effectively reduce the pressure loss of the pipeline system.

Compact structure, light weight: The structure of the lug butterfly valve is relatively compact, and the volume and weight are relatively small. This makes it advantageous in the case of limited installation space, and it is also convenient during transportation and handling.

Application field

Water treatment industry: widely used in urban water supply and sewage treatment systems. For example, it is used to regulate the amount of water in the water supply pipeline, and to control the flow of sewage and sludge in various pipelines in the sewage treatment plant.

Chemical industry: Used to transport various chemical raw materials and products, such as acids, alkalis, organic solvents, etc. However, the appropriate valve body and sealing material need to be selected according to the specific chemical medium to ensure the corrosion resistance and chemical stability of the valve.

Food and beverage industry: Because of its simple structure and easy cleaning, it is used in fluid transportation pipelines in food processing and beverage production. For example, the flow is controlled in milk, juice and other liquid conveying pipes.

Hvac system: In the heating, ventilation and air conditioning system, used to regulate the flow of hot and cold water, air and other media, to achieve temperature control and air conditioning functions.
