Turbine flange butterfly valve

Turbine flange butterfly valve, also known as turbine flange flap valve, is a type of valve widely used in industrial pipelines

The following is a detailed introduction:

1. Definition and Structure

Definition: Turbine flange butterfly valve is a valve that converts rotational motion into butterfly opening or closing action through a turbine transmission device, mainly used to control the flow of medium in pipelines.

Structure: This valve generally adopts a three eccentric multi-level metal hard sealing structure, and the valve seat and disc sealing surface are made of different hardness and stainless steel, with good corrosion resistance (mainly based on actual reports) (mainly based on actual reports) (mainly based on actual reports) (mainly based on actual reports) (mainly based on actual reports).

. Its sealing form often adopts a sealing structure, and the sealing material can be rubber, polytetrafluoroethylene, etc

2. Working Principle

The working principle of the turbine flange butterfly valve is mainly driven by manual rotation of the handwheel or electric device to drive the turbine device to work, and the turbine device then controls the movement of the valve stem, so that the butterfly plate rotates with the valve stem.

. The butterfly plate can be opened and closed once by rotating 90 degrees inside the valve body. When the rotation angle of the butterfly plate is between 0-90, the flow rate of the pipeline medium can also be adjusted and controlled

III. Application Scope

Turbine flange butterfly valves are widely used in industrial pipelines such as metallurgy, power, petrochemicals, water supply and drainage, and municipal construction where the medium temperature is ≤ 425. They are important equipment for regulating flow and cutting off fluids.

. In addition, it is also suitable for pipelines transporting various corrosive and non corrosive fluid media in engineering systems such as furnaces, coal gas, natural growth gas, liquefied petroleum gas, urban gas, cold and hot air, chemical smelting, and power generation environmental protection

4. Technical Features and Advantages

Simple Structure: The turbine flange butterfly valve has the characteristics of simple structure, small volume, light weight, and low material consumption.

Low fluid resistance: The streamlined design of the butterfly plate reduces fluid resistance loss, making it an energy-saving productGood sealing performance: Adopting multi-layer soft hard stacked sealing rings or metal hard sealing structures, the sealing performance is excellentGood adjustment performance: The rotation angle of the butterfly plate is adjustable, which can achieve accurate control of the flow rate of the pipeline mediumEasy installation and maintenance: The flange connection method makes installation and disassembly more convenient

V. Precautions for Installation and Maintenance

Before installation, it is necessary to clean the paint and other impurities on the sealing surface and confirm that the sealing surface is clean.

During the installation process, it is necessary to avoid damaging the sealing surface, and appropriate gaskets should be used when connecting with metal fittingsWhen the valve is not in use, the butterfly plate should be kept in a slightly open state and neatly stored in a ventilated and dry warehouse to prevent rubber agingRegularly check the sealing performance and operational flexibility of the valve to confirm its normal operation
