Electric butterfly valve can be used in railway locomotives and railway sleeper pads
Electric butterfly valves can be used in many fields, but they are not suitable for all places. So how should we choose appropriate electric butterfly valves? I have sorted out the characteristics of electric butterfly valve and its advantages and disadvantages for you before. Do you remember? It doesn't matter if I don't remember. I will recall a little later, mainly to talk about the application scope of electric butterfly valve.
When selecting electric butterfly valve, we should first understand its characteristics, and then select the environment. The characteristics of electric butterfly valve are that its shape can be designed as required, its stiffness can be adjusted, and it provides greater damping ratio, shear resistance, tensile resistance, compression resistance, and simpler device than butterfly valve. Its defects are high natural frequency, short service life, and limited operating environment. The temperature of ordinary operating environment should be controlled between - 30-70 ℃, and some chemically corrosive environments should select electric butterfly valves of suitable materials for use.
The current mainstream of electric butterfly valves suitable for consumption is: natural rubber, neoprene rubber, butadiene rubber; The market is full of electric butterfly valves based on reclaimed rubber, which have a hard hand feel but no butterfly valve performance, nonlinear load compression ratio, rough appearance, poor damping effect and are easy to age. Remember to choose carefully to prevent the purchase of such electric butterfly valves.
Main application scope of electric butterfly valve:
1. Steam electric butterfly valve
2. Valve products for railway locomotives and railway sleeper pads
3. Electric butterfly valve for bridge
4. Electric butterfly valve for construction engineering
Because the valve has the above characteristics, it is widely used on the bogie of locomotive running part. 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, transmission mounted bow block and ball joint, coupler buffer, etc.
The main function of electric butterfly valve applied to locomotive is to accept contraction stress, shear stress and changing moment, as well as to accept two or more kinds of stress synergism at the same time. All kinds of electric butterfly valves have certain special performance and play an important role in each other. The speed of the railway locomotive has improved from time to time, and the dynamic effect on the line has increased sharply, causing fierce wear of the line, tire and local components of the locomotive running. Therefore, the application of electric butterfly valves is increasing.
From the above, we can draw a conclusion that we should use different products when using different centers, and different products will produce different effects. But no matter what products we use, we should fully understand the characteristics of the products in the early stage. As long as we choose the right products and use the right center, the products can really serve us.
