Electric globe valve is a commonly used fluid control device, which can control the opening and closing of the valve through electric actuators, so as to realize the cut-off and regulation of the fluid. The following is a detailed introduction to the structure of the electric globe valve.
OneBody:
The valve body of the electric globe valve is usually made of cast iron, carbon steel, stainless steel and other materials, which has good corrosion resistance and high temperature resistance.
Second, the valve disc
The disc is a key component of the electric shut-off valve, which is responsible for controlling the passage of the fluid. The disc is usually made of metal materials, such as stainless steel, cast iron, etc., which has high wear resistance and corrosion resistance.
IIISealing structure:
The sealing structure of the electric globe valve is mainly in the form of metal seal and soft seal. Metal seals generally use spherical seals or conical seals, which can provide good sealing performance. The soft seal generally adopts rubber sealing ring or PTFE sealing ring, which has good sealing performance and corrosion resistance.
FourthElectric Actuators:
The electric shut-off valve uses an electric actuator to control the opening and closing of the valve. Electric actuators are usually composed of electric motors, reducers, limit switches and other components, which can provide large driving force and precise control capabilities.
FiveTransmission:
The transmission device of the electric globe valve is generally composed of a transmission rod, a transmission shaft and other components, which can transmit the movement of the electric actuator to the valve disc to realize the opening and closing of the valve.
In short, the structure of the electric globe valve is complex, consisting of multiple components, each of which works together to achieve the function of fluid cut-off and regulation. The specific structural design and selection need to be selected according to the actual working conditions and use requirements.
