Ouyan Electric High Temperature Butterfly Valve

The Ouyan electric high-temperature butterfly valve is mainly composed of a valve body, a butterfly plate, a valve seat, a valve stem, and an electric actuator. The valve body is usually made of high-temperature resistant stainless steel or carbon steel material to ensure that it will not deform or be damaged under high temperature conditions. The butterfly plate is connected to the valve stem and is driven by an electric actuator to rotate, thereby controlling the opening and closing of the valve.

1、 Structure and Composition

The electric high-temperature butterfly valve is mainly composed of a valve body, a butterfly plate, a valve seat, a valve stem, and an electric actuator. The valve body is usually made of high-temperature resistant stainless steel or carbon steel material to ensure that it will not deform or be damaged under high temperature conditions. The butterfly plate is connected to the valve stem and is driven by an electric actuator to rotate, thereby controlling the opening and closing of the valve.

2、 Working principle

The working principle is relatively simple. When the electric actuator receives a control signal, it drives the valve stem to rotate, which in turn drives the butterfly plate to rotate inside the valve body. The rotation angle of the butterfly plate determines the opening of the valve, thereby regulating the flow rate of the medium. When the butterfly plate is parallel to the direction of medium flow, the valve is fully open; When the butterfly plate is perpendicular to the direction of medium flow, the valve is in a fully closed state.

3、 Characteristics and advantages

High temperature resistance: Made of high temperature resistant materials, it can work stably in environments up to 1100 degrees Celsius.

Compact structure: The valve has a compact design, light weight, small space occupation, and is easy to install and maintain.

Flexible operation: Due to the use of electric actuators, the valve has a small operating torque, quick opening and closing, and fast response speed.

Good sealing performance: The sealing structure design of the valve is reasonable and can achieve sealing with zero leakage rate.

Wide applicability: Suitable for various media, including high-temperature flue gas, dust, air, and exhaust gas.

Remote control: Valves can be used in conjunction with various actuators to achieve remote control and improve automation levels.

4、 Application Fields

Ouyan Electric High Temperature Butterfly ValveWidely used in the following fields:

Metallurgical industry: used to control high-temperature gases in equipment such as blast furnaces and converters.

Building materials industry: used for high-temperature flue gas regulation in equipment such as cement kilns and glass kilns.

Chemical industry: used for high-temperature gas control in equipment such as reaction vessels and cracking furnaces.

Power station: used for regulating high-temperature steam in equipment such as boilers and steam turbines.

Glass industry: used for high-temperature flue gas control in glass melting furnaces.

5、 Installation and maintenance

When installing an electric high-temperature butterfly valve, the following points should be noted:

Installation position: The valve should be installed in a location that is easy to operate and maintain.

Installation direction: The installation direction of the valve should conform to the flow direction of the medium.

Bypass valve: Butterfly valves with bypass valves should be opened before opening.

Basic setting: For heavy butterfly valves, a solid foundation should be set up.

In terms of maintenance, regularly check the sealing condition of the valve and the working status of the electric actuator, replace worn parts in a timely manner, and ensure the normal operation of the valve.

6、 Selection precautions

Temperature range: Select the temperature range of the electric high-temperature butterfly valve according to the operating conditions to ensure that the valve can work normally and has sufficient margin.

Material selection: Choose suitable high-temperature resistant materials based on the characteristics of the medium and temperature requirements, such as high-temperature alloys or ceramic materials.

Sealing performance: Understand the sealing performance requirements of the valve, choose a suitable sealing structure, such as metal seal or soft seal structure, to ensure the sealing reliability of the valve.
