It has good elasticity and toughness, and also has good seismic performance in use. In addition to its own good performance, the butterfly valve processed has improved its elasticity. Therefore, butterfly valves have played a good role in some anti-seismic machinery, passenger cars, delivery trucks and other machinery. In application, they can also be made into different styles according to different needs. Let's take a look at the advantages of butterfly valves.
The electric butterfly valve has simple structure, easy use and maintenance, almost no need for repair, no wear, no rust, no need for oil lubrication, is insensitive to the effect 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 electric butterfly valve has the above characteristics, it is widely used on the bogie of the running part of the locomotive. Electric butterfly 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 butterfly valve, bow block and ball joint of transmission device, coupler buffer, etc.
The electric butterfly 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 butterfly valves, I believe that all you can think of are butterfly valves made of metal. These butterfly valves have a good auxiliary function whether they are used in mechanical equipment or small toys. In fact, the butterfly valve we will introduce below is a butterfly valve, which is different from the butterfly valve we usually see, but it is also often used in large mechanical equipment, playing a good role as a valve. To raise your awareness, let's take a look at the application fields of butterfly valves. The shape of the butterfly valve is completely unlimited, and it can produce relatively large elastic deformation, which is very easy to meet the nonlinear requirements, and the effect of vibration and sound insulation is also very good. Compared with the butterfly valve, the shape of the composite butterfly valve is limited by the metal screw butterfly valve, and the requirements for linearity are very high.
