There are four types of ball check valves:

1. Quick opening ball check valve refers to the position where the cover of the disassembled ball valve is fixed with quick opening bolts, while the traditional position is fixed with ordinary bolts. Supply scope: DN50 to DN100.

2. Groove type ball check valve refers to a groove type valve that is connected to the pipeline and fixed to the pipeline through clamps. DN50 to DN150.

3. The threaded ball type sewage check valve refers to the connection with the pipeline that relies on threaded threads. Supply scope: DN20 to DN50.

4. Flange type ball check valve refers to the flange type connection form with the pipeline. DN50 to DN200.

Introduction to Ball Check Valve

Ball check valve is a type of valve used in pipelines, mainly to prevent fluid backflow in the pipeline, prevent medium from flowing back to raw material storage tanks, pumps and other devices, and prevent damage or pollution. It is usually suitable for fluid control systems in industries such as municipal, construction, chemical, metallurgical, petroleum, and textile.

Working process of ball check valve

The main components of a ball check valve include a sphere, a valve body, a sealing ring, etc. When the medium flows normally, the ball will automatically rise along the streamline, allowing the medium to pass through without resistance. When the flow is reversed, the ball will quickly descend and tightly adhere to the valve seat, thereby preventing the medium from flowing in the opposite direction. If the direction of medium flow changes, the ball will quickly disconnect to ensure timely closure when the direction of medium flow is reversed, preventing the occurrence of medium backflow.

5 characteristics of ball check valve:

1. Simple structure and small volume: Ball check valves have a relatively simple structure and small volume compared to other types of valves, making them easy to install and maintain.

2. Quick closure: The ball of the ball valve can quickly return to its original position when the direction of the medium flow changes, thus completing the complete shut-off effect in a short period of time.

3. No noise: The ball check valve has no obvious noise during operation, which can ensure the normal operation of the pipeline system.

4. High flow capacity: The ball check valve adopts a spherical structure, and the resistance to fluid flow through the valve is relatively small, resulting in strong flow capacity.

5. No external force required: The opening and closing of the ball check valve can be achieved by relying solely on the pressure of the medium, without the need for additional external force.

In summary, ball check valves have the advantages of simple structure, small volume, fast closure, no noise, large flow capacity, and no need for external force. They are widely used fluid control valves.
