The Worm Gear flange ball valve is a valve widely used in fluid systems. Its working principle is to open and close the valve through the meshing of the turbine worm. The turbine is installed on the ball valve stem. When the turbine rotates, the worm rotates accordingly, thereby driving the valve stem and the ball to rotate to achieve valve control. It is mainly used to cut off, distribute and change the flow direction of the medium in the pipeline. It has many characteristics and advantages, making it very popular in pipeline systems in various industrial applications such as petroleum, chemical, electric power, heat, metallurgy, medicine, fertilizer, saline, chemical fiber, water supply, environmental protection, industrial and civil construction, nuclear industry, etc.
The turbine transmission mechanism is an important part of the turbine transmission flange ball valve, which has the following characteristics: high transmission efficiency: the meshing transmission efficiency of the turbine worm is high, making the valve open and close more quickly; small operating torque: due to the meshing principle of the turbine worm, the operating torque is small, which is convenient for manual operation, or an electric actuator can be added as needed to use electric operation; high reliability: the meshing structure of the turbine worm is simple, the failure rate is low, the maintenance is easy, and the reliability is high.
Main features of Worm Gear flange ball valve
1. Low fluid resistance: The design of the ball valve makes it almost free of fluid resistance when opened, and its resistance coefficient is equal to that of a pipe section of the same length.
2. Simple structure, small size and light weight: This makes the ball valve easy to install and maintain.
3. Tight and reliable: The ball valve has good sealing performance, and plastic and other materials are widely used as sealing surfaces, which are suitable for vacuum systems.
4. Easy operation: It opens and closes quickly, and only needs to rotate 90° to achieve full opening or full closing, which is convenient for remote control.
5. Easy maintenance: The ball valve has a simple structure, and the sealing ring is usually movable, which is easy to disassemble and replace.
6. Wide range of applications: The diameter of the ball valve ranges from a few millimeters to a few meters, and it is suitable for a wide range of media, from high vacuum to high pressure
