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.

Every job has risks, and every profession also has risks. What are the risks faced by the plastic coated pneumatic butterfly valve profession? How to deal with that?
The plastic coated pneumatic butterfly valve is a traditional industry of the hardware industry in China. Under the background of economic globalization, the plastic coated pneumatic butterfly valve profession strives to change its thinking, meet the needs of consumers at different levels at home and abroad, and complete the plastic coated pneumatic butterfly valve profession in a sound and fast way. Tongfeng pneumatic butterfly valve is to strengthen the cooperation with pneumatic butterfly valve equipment company, select backward equipment, and gradually select microcomputer processing and semi-automatic production and processing; Second, increase investment in technological transformation, especially for some large companies to actively introduce and digest international advanced processing centers; The third is to work hard on commodity surface treatment and processing technology to improve the durability and decoration of commodities.
The year 2011 is the year of the 12th Five Year Plan. As far as the plastic wrapped pneumatic butterfly valve profession is concerned, it is both a challenge and an opportunity. With the rapid development of pillar industries such as instruments, surfaces and sensors, and the continuous expansion of demand for pneumatic butterfly valves in national defense, security, finance and other systems, the plastic coated pneumatic butterfly valve market contains great potential and unlimited business opportunities.
Plastic coated pneumatic butterfly valve occupation accelerates commodity structure adjustment
The "12th Five Year Plan" is a critical period for the development and promotion of the pneumatic butterfly valve industry. The pneumatic butterfly valve industry will continue to adhere to the market orientation and accelerate the adjustment of commodity structure. Over the years, the market's demand for high-end plastic coated pneumatic butterfly valves has increased at an annual rate of more than 50%, and the import of plastic coated pneumatic butterfly valves has also increased at an annual rate of 30%. Tongfeng pneumatic butterfly valves have increased efforts to adjust the structure of goods, taking high-tech, high value-added goods and car locks as the key points of development; Work hard on independent intellectual property rights, form our own central technology and patents, accelerate the transformation of scientific and technological achievements, and meet the needs of consumers at different levels.
