The working principle of PP ball valve

Tags :

Category : Blog

The opening and closing part of the PP ball valve is a sphere with a circular channel, which rotates around an axis perpendicular to the channel, and the sphere rotates with the valve stem to achieve the purpose of opening and closing the channel. The PP ball valve can be closed tightly with only a 90-degree rotation and a small torque.

According to the requirements of the working conditions, different driving devices can be assembled to form a variety of ball valves with different control methods, such as electric ball valves, pneumatic ball valves, hydraulic ball valves, etc.

Working principle of PP ball valve:

When the ball PP valve rotates 90 degrees, it should show a spherical surface at the inlet and outlet, so as to close the valve and cut off the flow of the medium.

Advantages of PP ball valve

1. The PP ball valve is not restricted by the installation direction, and the flow direction of the medium can be arbitrary. The fluid resistance is small, and the full-bore ball valve basically has no flow resistance.

2. The PP ball valve has a simple structure, relatively small size, light weight and easy maintenance.

3. Close and reliable. It has two sealing surfaces, and the current sealing surface materials of ball valves are widely used in various plastics, which have good sealing performance and can achieve complete sealing. It has also been widely used in vacuum systems.

4. PP ball valve is suitable for frequent operation, opening and closing quickly and lightly. It is easy to operate and open and close quickly. It only needs to rotate 90° from fully open to fully closed, which is convenient for remote control.

5. The maintenance is convenient, the structure of the ball valve is simple, the sealing ring is generally movable, and it is convenient to disassemble and replace.

6. PP ball valve has good sealing performance. When fully open or fully closed, the sealing surface of the ball and the valve seat is isolated from the medium, and the medium will not cause erosion of the valve sealing surface when the medium passes.

7. It has a wide range of applications, with a diameter ranging from a few millimeters to a few meters, and can be applied from high vacuum to high pressure.

8. Because the PP ball valve has wiping properties during the opening and closing process, it can be used in media with suspended solid particles.

9. PP ball valve has low fluid resistance, no vibration and low noise.

3. Manual air valve

4. Electric air volume control valve

5. Airtight damper

Installation Precautions

The air volume control valve installation is carried out in accordance with the national building standard design “Air Valve Selection and Installation”. described as follows: 

1. For the damper products transported to the construction site, the installation unit should report to the supervisor for acceptance, and check the certificate, test report and installation instruction document according to the packing list, and verify the product model, specification, material, logo and Whether the control method meets the requirements of the design documents, it should be recorded and signed by all parties for confirmation.

2. Before installing the air valve in place, check whether its structure is firm and tight, and conduct a switch operation test to check whether it is flexible and reliable; the electric air valve shall be energized and tested one by one, and test records shall be made.

3. Before the air valve is in place, it must be checked whether its applicable scope, installation position, air flow direction and operating surface are correct.

4. The opening and closing direction and opening angle of the air valve should be accurately marked on the visible surface.

5. For air valves installed in high places, the manual operating device should be 1.5-1.8m away from the exposed or operating platform.

6. The effective distance between the operating surface of the air valve and the wall, ceiling and other equipment and pipes shall not be less than 200mm, and the air valve shall not be installed in the structural layer or hole. The slit width around the valve should be greater than 150mm.

7. Check whether the flange size reserved for the connecting air pipe, the matching drill diameter and hole distance, the flatness and parallelism of the flange surface, the material and thickness of the gasket, and the connection method of the non-metallic air pipe meet the requirements.

8. Check whether the position and method of the support and hanger meet the requirements of the specification or design documents. A single damper with a weight greater than 50kg should be provided with a separate support and hanger; electric damper should generally be equipped with a separate support and hanger; for soft non-metal air duct systems, a separate support and hanger should also be provided for the damper .

9. The air valve used in the clean ventilation system must be cleaned as required before installation, and the two ends must be sealed after reaching the corresponding clean standards, and the sealing plate can be removed after it is in place. The inner surface of the air valve of the scrubbing purification air conditioning system should be made of materials that do not drop fibers. The scrubbed air valve must not be stored in a room without walls, floors, doors and windows, and the temporary storage place must be kept clean.
