Performance of welded ball valve

Release date: November 19, 2018

Understanding the knowledge of welding ball valve can effectively avoid wrong operation, reasonable maintenance, and improve the service life of welded ball valve.

 Welded ball valve

Performance of welded ball valve:

1. Without maintenance, adjustment and lubrication, it is easy to install and operate reliably for a long time at low operating cost. The surface adopts spray plastic treatment technology, with beautiful luster, which has been in the forefront level in China. There will be no external leakage. The valve body is of welded construction, so the valve is light and easy to insulate. It is very simple to install the adjusting mechanism. The operating handle can be removed and installed in reverse direction.

2. Since the valve seat is composed of carbon fiber reinforced Teflon sealing ring and disc spring, it has strong adaptability to the change of pressure and temperature, and there will be no sliding within the marked pressure and temperature range.

3. The machining process of the ball has advanced computer detector tracking detection, so the machining accuracy of the ball is high.

4. As the valve body material is the same as the pipe material, it will not cause uneven stress and deformation due to earthquake and vehicle passing through the ground, so the pipeline is aging resistant.

5. Integral full welding, equal diameter and variable diameter channel, fixed ball and floating ball, double piston effect sealing system, automatic injection sealant type bearing.

6. In order to prevent static electricity, steel balls and springs are respectively installed between the valve stem and the ball and between the valve stem and the packing box, which can keep the electric conduction between all parts of the valve and the valve body, and let the current pass through the area to release static electricity. Not only to prevent fire, but also to prevent corrosion, to achieve temporary cut-off for timely maintenance.

7. The valve stem anti dropping function is because the valve stem is affected by the pressure in the valve, and the force is always generated, so the valve rod is designed as an anti dropping structure.

8. The thrust washer support of low friction material is used to push the pressure to the valve stem, so that the valve stem only serves to transmit torque. The valve seat of the welded ball valve is composed of carbonized Teflon sealing ring and spring, so it has strong ability to change pressure and temperature, and there will be no leakage within the marked pressure and temperature range. Moreover, the sealing ring body is made of PTFE with content of 0.2C (carbon), and the package tube is completely free of leakage (0).
