The top entry ball valve is a commonly used fluid control valve and is often used in piping systems.
What are the main features of the top entry ball valve?
The main feature of the top-entry ball valve is that the ball enters and disassembles from the upper part of the valve, so it is called "top-entry".
This design makes it easier to repair and replace internal parts such as balls and races.
The structure of the top entry ball valve:
The top entry ball valve is usually composed of a valve body, a ball, a valve stem, a seat ring, a sealing ring, and a transmission device.
1. The valve body usually has a larger hole diameter, which is suitable for high flow and high pressure conditions.
2. The ball is connected with the transmission device through the valve stem, which can be rotated to open and close the valve.
3. The seat ring is located inside the valve body and is used in conjunction with the ball to ensure the sealing performance of the valve.
What are the advantages of top entry ball valves?
1. Detachable
Since the ball can be accessed and removed from above, there is no need to remove the entire valve body from the pipeline, saving time and effort.
2. Good sealing
The sealing performance of the ball and the seat ring is good, which can effectively prevent fluid leakage.
3. Easy maintenance
The structure of the ball valve is relatively simple, and it is relatively easy to maintain and clean.
Where can top entry ball valves be used?
Top entry ball valves are widely used in petrochemical, metallurgy, energy, chemical, water treatment and other fields.
What is the top entry ball valve used for?
The top-entry ball valve is suitable for high-temperature and high-pressure fluid control, and can realize the functions of full opening, full closing and flow adjustment. Through reasonable selection of materials and sealing design, the top entry ball valve can also be used in corrosive media.
Summarize
The top-entry ball valve is a common and reliable valve type, which has the advantages of convenient maintenance, good sealing and wide application range, and is suitable for fluid control needs in various industrial fields.
