Rubber pneumatic butterfly valve can be used in railway locomotives and railway sleeper pads
Rubber pneumatic butterfly valve can be used in many fields, but it is not suitable for all places. So how should we choose the appropriate rubber pneumatic butterfly valve? Before, Xiao Bian sorted out the characteristics of rubber pneumatic butterfly valve and its advantages and disadvantages. 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 rubber pneumatic butterfly valve.
When selecting pneumatic butterfly valve, we should first understand its characteristics, and then select the environment. The characteristics of rubber pneumatic butterfly valve are that its shape can be designed as required, its stiffness can be adjusted, its damping ratio is greater than that of spring, its shear resistance, tensile resistance, compression resistance, and its device is simpler. 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 rubber pneumatic butterfly valves with suitable materials for use.
The main rubber pneumatic butterfly valves suitable for consumption are: natural rubber, neoprene rubber, butadiene rubber; The market is full of pneumatic butterfly valves based on reclaimed rubber, which are hard to handle without springiness, nonlinear in load compression ratio, rough in appearance, poor in damping effect and easy to age. Remember to choose carefully to prevent the purchase of such pneumatic butterfly valves.
Main application scope of rubber pneumatic butterfly valve:
1. Rubber pneumatic butterfly valve for steam
2. Rubber damping products for railway locomotives and railway sleeper pads
3. Rubber pneumatic butterfly valve for bridge
4. Rubber pneumatic butterfly valve for construction engineering
Because rubber shock absorber has the above characteristics, it is widely used on the bogie of locomotive running part. The rubber pneumatic butterfly valves used on electric locomotives include central support rubber cones, axle box pull rod elastomers, side bearing rubber stacks, motor suspension rubber pads, elastic wheels, elastic gears, air springs, transmission mounted bow rubber blocks and ball hinges, coupler rubber buffers, etc.
The rubber pneumatic butterfly valve applied to locomotives is mainly used to accept the contraction stress, shear stress, change the torque, and simultaneously accept the combined action of two or more stresses. Various rubber pneumatic 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 rubber pneumatic butterfly valve 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.

At present, China's iron and steel industry lacks independent innovation and original innovation, and the central technology has not yet been fully controlled, which is still in the stage of pursuit, leading to the fact that most spherical compensators can not fully meet the needs of the applied steel industry, and the compensator market lacks driving force, which mainly includes:
1) The contradiction of overcapacity is prominent, which is not conducive to the balance of market supply and demand;
2) The decline of enterprise benefits is not conducive to the vitality of the progressive economy;
3) The price of ball type compensator drops too fast.
The expansion of the contradiction between supply and demand has seriously hindered the development of the spherical compensator market. Experts believe that if we want to completely change the current rigid market pattern, we must start from adjusting the industrial structure, improving the technical content of the compensator products, accelerating the industrial upgrading, and strengthening the overall competitiveness of the industry.
