What Is The Floating Ball Valve? What Are The Characteristics?
What is the floating ball valve?
Ball valves without fixed shafts are called floating ball valves. The floating ball valve body has two seat sealing rings. There is a ball clamped between them, and the ball has through a hole. It is equal to the diameter of the pipeline through the hole diameter. It is called the full-diameter ball valve. The diameter of the through hole is slightly less than the inner diameter of the pipeline. It is called the reduced-diameter ball valve. The ball can rotate freely in the seat ring with the help of the stem. In the opening, the ball hole and pipe diameter alignment have ensured that the pipeline working medium resistance is small. When the stem rotates 1/4 turn, the ball hole is perpendicular to the channel of the valve. The ball is tightly pressed on the valve seat ring at the outlet end by the preload force. Medium pressure is added to the two seat rings, so as to ensure the valve seal. The ball valve is a one-side forced seal.
What are the characteristics of the floating ball valve?
1. The ball valve can be fully closed and fully opened by rotating 90 degrees, and it can be opened and closed quickly. Compared with gate valves and globe valves of the same specifications, ball valves are small in size and light in weight, which is convenient for pipeline installation.
2. The valve stem flight-proof structure: the valve stem is installed under the pressure to prevent flying out. At the same time, after the fire, the valve body can contact the metal to ensure that the seal of the valve stems.
3. The ball valve is a ball with a circular hole as the opening and closing parts. Driven by the valve stem, the ball rotates around the center of the valve stem for 0 to 90 degrees to complete the opening and closing functions. With the characteristics of a compact switch, you can close the valve, and cut off the pipeline medium by rotating 90 degrees. The diameter of the sphering channel is the same as the diameter of the pipeline. The flow resistance is small, and the flow capacity is large. The valve stem is installed under the valve stem, to prevent the accident of the valve stem out. The stem also ensures the safety of use.
4. In a variety of valves, the flow resistance of ball valves is very small. When the full-diameter ball valve opened, the ball channel, valve body channel and connecting pipe diameter are equal to and into a diameter.
5. The locking device: in order to prevent the valve switch operation, there are locking holes in the fully open state and fully closed state to ensure that the valve is in the correct position.
6. Advanced valve seats: designed with many years of manufacturing experience with ball valves, we can ensure the valve seal, low friction coefficient, and small operating torque. We also have a variety of valve seat materials, and a wide range of adaptations.
7. Switch the correct handle: it adopts the use of a flat-head valve stem. The connection of the handle will not be misplaced, so as to ensure that the handle indicates the switch state and the valve.
Features and performance of the floating ball valve
The floating ball valve ball is floating. Under the action of medium pressure, the ball can produce a certain displacement and pressure on the sealing surface of the outlet end, to ensure that the outlet end is sealed.
The floating ball valve has a small size, light weight, simple structure, and good sealing, but the ball bears the load of the working medium which is all passed to the outlet sealing ring. Therefore, we should consider whether the sealing ring material can withstand the working load of the ball medium.
The ball body has a free-floating function which can better ensure the sealing. The ball valve is a ball with a circular a hole as the opening and closing parts. It is driven by the valve stem ball around the center of the valve stem for 0 to 90 degrees of rotation to complete the opening and closing functions. With the characteristics of a compact switch, you can close the valve, and cut off the pipeline medium by rotating 90 degrees. The diameter of the sphering channel is the same as the diameter of the pipeline. The flow resistance is small, and the flow capacity is large. The valve stem is installed under the valve stem, which prevents the accident the valve stem and ensures its safety of use.
Features and performance of the fixed ball valve
The fixed ball valve ball is fixed. It does not move after compression. The fixed ball valve is with a floating seat so that the sealing ring is pressed on the ball to ensure sealing. It is usually equipped with bearings on the upper and lower shafts of the ball. The operation torque is small, which is suitable for high-pressure and large-diameter valves.
The fixed ball valve is suitable for a variety of medium and high-pressure pipelines. It is used to cut off or connect the medium in the pipeline and choose different materials. It can be applied to water, steam, oil products, liquefied gas, natural gas, gas, nitric acid, acetic acid, oxidizing medium, urea and other media. It is widely used in petrochemical, electric power water conservancy and other industries. Common actuation methods for fixed ball valves are worm gear drive, manual, electric and pneumatic. Most fixed ball valves are flanged, but there are also soldered fixed ball valves.
The fixed ball valve and the floating ball valve are roughly different.
a. The floating ball valve - the spool ball rotates freely between the two seat rings with the help of the stem.
b. The fixed ball valve - the ball valve with a spool ball connects to the stem and rotates in the center of the stem with a floating ball and a flexible sleeve seat.
