Can electric butterfly valves 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 suitable 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 it for you 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 easier installation than butterfly valve. Its defects are high natural frequency, short service life, and limited operating environment. The temperature of the common operating environment should be controlled between - 30-70 ℃. For some chemically corrosive environments, electric butterfly valves with suitable materials should be selected for use.
At present, the mainstream of electric butterfly valves suitable for consumption are: natural rubber, neoprene rubber, butadiene rubber; The market is full of electric butterfly valves made of recycled rubber, which are hard to handle without butterfly valve performance, non-linear load compression ratio, rough surface, poor damping effect and easy to age. Remember to choose carefully and avoid purchasing such electric butterfly valves.
Main application scope of electric butterfly valve:
1. Electric butterfly valve for automobile
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 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 contraction stress, shear stress and modification torque, as well as the combined action of two or more stresses 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 components of the running part of the locomotive. As a result, the application of electric butterfly valves is getting more and more advanced.
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. However, no matter what products we use, we should fully understand the characteristics of the products in the early stage. Only by choosing the right products and using the right center, can the products really serve us. Our Dongfeng Xizhen Electric Butterfly Valve Co., Ltd. has different valve products.
