Characteristics and introduction of Metal Seated Butterfly Valves

Introduction

The butterfly valve consists of a valve body and a disc-shaped butterfly plate that can rotate along the axis. The rotational movement enables the valve to open and close effectively. To generate highly similar content, the text can be rearranged as follows: "A disc-shaped butterfly plate is attached to the opening and closing part of the valve, which is designed to rotate around the axis of the valve body. This rotation allows for effective opening and closing of the valve."

Structure

The primary components of a metal seated butterfly valve include the valve body, valve stem, butterfly plate, and sealing ring. Within the valve body, there is a cylindrical structure with a relatively short axial length, housing the butterfly plate securely.

Working principle

The butterfly plate is responsible for regulating medium flow by changing its deflection angle. It is operated by a valve stem, which rotates it by 90° to complete one cycle of opening and closing. This mechanism offers precise control over the fluid, enhancing the efficiency of your system.

Working conditions and media

Butterfly valves are extensively utilized in various engineering systems for the conveyance of both corrosive and non-corrosive fluids. These systems include generators, coal gas, natural gas, liquefied petroleum gas, city gas, hot and cold air, chemical smelting, power generation, and environmental protection. Additionally, they find application in building water supply and drainage systems. Their main purpose is to regulate and interrupt the flow of the medium within the pipelines.

Characteristics

The reliable sealing performance is ensured due to the triple eccentric structure, which eliminates the uneven load on the sealing seat and extends its service life. This design also prevents the butterfly plate from touching the sealing seat during opening, ensuring a trustworthy seal. Moreover, the product offers advantages such as high temperature resistance, wear resistance, and corrosion resistance.
