The ball valve itself has good elasticity and toughness, and also has good seismic performance in use. In addition to its own good performance, the ball valve processed has improved its elasticity. Therefore, the ball valve has played a good role in some earthquake resistant machinery, buses, trucks and other machinery, and can be made into different styles according to different needs in application. Let's see what advantages the ball valve has.
The shock absorber has simple structure, convenient use and maintenance, almost no need for repair, no wear, no rust, no need for oil lubrication, is insensitive to the role of water and dust, does not produce sudden damage in use, is safe and reliable, low cost and has a long enough service life.
As the pneumatic ball valve has the above characteristics, it is widely used on the bogie of the running part of the locomotive. The pneumatic ball valves used on electric locomotives include central support cone, axle box pull rod elastomer, side bearing stack, motor suspension pad, elastic wheel, elastic gear, air ball valve, bow block and ball hinge of transmission device, coupler buffer, etc.
The pneumatic ball valve applied to the locomotive is mainly used to bear the compression stress, shear stress and torsional moment, as well as two or more stress combinations. Speaking of ball valves, I believe that all you can think of are metal ball valves, which have a good auxiliary function whether they are used in mechanical equipment or small toys. In fact, the ball valve we will introduce below is a ball valve, which is different from the common ball valve, but it is also often used in large mechanical equipment, playing a good role as a valve. In order to raise your awareness, let's take a look at the application fields of ball valves. The shape of the ball valve is completely unrestricted, and can produce relatively large elastic deformation, which is very easy to meet the requirements of nonlinearity, and the effect of vibration and sound insulation is also very good. Compared with the ball valve, the shape of the composite ball valve is limited by the metal screw ball valve, and the requirements for linearity are very high.
