What Is The Structural Composition Of The Sanitary Diaphragm Valve?
Sanitary Diaphragm Valve is a valve specially designed to meet the requirements of hygiene and cleanliness in industries. So do you know what the structure of sanitary diaphragm valve is?
Structural composition of sanitary diaphragm valve:
Valve body: usually made of corrosion-resistant materials such as stainless steel, its shape design facilitates the smooth flow of fluid in the valve body, reducing the possibility of dead corners and dirt accumulation. There are connection interfaces at both ends of the valve body, which can be connected to pipelines or equipment. Common connection methods include clamp connection, welding connection, etc.
Actuator: used to drive the movement of the valve stem and diaphragm to achieve valve control. Common actuators are manual, pneumatic and electric. Manual actuators are generally handwheels or handles, which realize the opening and closing of valves through human operation; pneumatic actuators use compressed air as a power source, which moves quickly and is suitable for occasions that require quick response; electric actuators are powered by electric motors, which can achieve remote control and automatic operation.
Diaphragm: It is a key component of sanitary diaphragm valves, generally made of rubber, polytetrafluoroethylene (PTFE) and other materials. The diaphragm divides the internal space of the valve body into two parts, the upper part is connected to the actuator, and the lower part is in contact with the fluid medium. The diaphragm has good flexibility and corrosion resistance, and can effectively prevent medium leakage and external impurities from entering while ensuring the normal operation of the valve.
Valve stem: One end is connected to the diaphragm and the other end is connected to the actuator. The function of the valve stem is to transmit the driving force of the actuator to drive the diaphragm to move, thereby realizing the opening and closing of the valve.
The work of the sanitary diaphragm valve is based on the movement of the diaphragm to control the on and off of the fluid. When the actuator is activated, the diaphragm is driven to move through the valve stem.
