Difference between function classification and appearance classification of rubber shock absorber
The rubber shock absorber is actually a shock absorber element, but do not underestimate this element. Its shock absorption effect has been used in various machinery, cars, trains, ships, aircraft and even aircraft. It can be said that its role has been used in all means of transportation, but it is not only the same component that can do this, but there are many types of rubber shock absorbers that can do this. What are the rubber shock absorbers?
In fact, there are two classifications of rubber shock absorber, one is function classification, the other is appearance classification:
The rubber shock absorbers are roughly classified as follows according to their functions:
1. Support various installed rubber shock absorbers in a narrow sense;
2. Rubber buffer for shock absorption;
3. Rubber springs used as mechanical actuating parts;
4. Dynamic shock absorber to eliminate vibration of specific vibration frequency;
5. Rubber couplings are also included in the category of rubber shock absorbers.
Rubber shock absorbers are classified as follows according to their narrow appearance:
1. Compression type: this type is a rubber shock absorber mainly used in the compression direction. The advantage is that the load acceptance force is large, but the elastic coefficient in the tightening direction cannot be too low;
2. Shear type: this type is a rubber shock absorber mainly used in the shear direction. Its load bearing force is small, but it has the advantage that the elastic coefficient can be selected very small;
3. Composite type: it is a rubber shock absorber used in the combined direction of compression and shear, with the middle characteristics of compression and shear;
4. Cylindrical type: This type of rubber damper can be used for vibration reduction in vertical, axial, twisting, prying and other directions. It is similar to the compact rubber alkali vibrator in the vertical direction of the shaft. Its load acceptance force is generally large, but the elastic coefficient cannot be too small.

The development of threading pneumatic butterfly valve enterprises benefits from the development of domestic industrialization
The development of threaded pneumatic butterfly valves in China is under increasing pressure from resources and environment. An important way to alleviate resource constraints is to carry out green manufacturing. In the future, it will continue to actively promote the brand operation and promote the all-round development of pneumatic butterfly valve project. In terms of products, medium and high-end products will accelerate the localization of quality research and development, and the whole process from design, manufacturing, packaging, transportation, application to scrap disposal should consider the least waste, the lowest emissions, the highest resource application rate and the smallest environmental impact, so as to make enterprise benefits and social benefits harmonious and optimized; In terms of circulation, explore various forms of value-added services to bring value and benefits to customers. From the provision of a single set of pneumatic butterfly valve to the provision of line maintenance treatment plans and customized services, the proportion of sales revenue of pneumatic butterfly valve manufacturers will gradually increase.
With the comprehensive deepening of reform and opening up, the competition in China's threading pneumatic butterfly valve market has become more and more fierce. Many foreign companies have entered China's market from time to time, and have taken root in China. They use China's low-cost labor force to consume their brand products for higher profits.
Under such pressure, how to make our products not suppressed and develop better and better has become a big issue for many enterprises to consider. The lack of big brands in China is also a problem that needs to be handled by enterprises. So many enterprises have poured into the Chinese market from abroad, which means that more pneumatic butterfly valve enterprises need to break the company from time to time, so that their development can gradually become an enterprise that can integrate with the international market. This reverse pressure is very helpful for the development of our pneumatic butterfly valve.
Compared with these foreign-funded enterprises, many pneumatic butterfly valves in China are short of big brands, which makes our competition in the pneumatic butterfly valve market relatively poor. Therefore, China has adopted the familiar price war, but because it is in the Chinese pneumatic butterfly valve market. As a result, the price war has few advantages for Chinese enterprises. The best way for China is to create a large brand of high-strength screws with my own creativity, which can be integrated with international pneumatic butterfly valves. In this way, the competition in the market will be intensive or precise, and the progress of technology and management efficiency will play a leading role in the overall growth, The result is the increase of added value and profit. Because, if it is investment, the output will certainly increase, but the cost will also increase, which is unsustainable. The current problem lies in the considerable defects in the entrepreneurial environment and the government's management of science and technology education.
As long as we can establish a system and policy environment conducive to innovation and entrepreneurship through reform, the integrity can significantly improve the technical level and added value of China's pneumatic butterfly valves in a short period of time. At present, the advanced pneumatic butterfly valves in the world are facing big or small technological breakthroughs. If China's pneumatic butterfly valves can seize this great opportunity, give full play to their own advantages, and develop some competitive international products, it is also complete and possible.
