The main advantages of this design are as follows:
1. Improve inflation efficiency
From one song to two, to three, to four... It is not hard to imagine that the more rings, the more effective the reduction of the internal space of the skin capsule. Improving the inflation efficiency of pneumatic butterfly valves may not play an important role in ordinary binary and ternary pneumatic butterfly valves. However, if the diameter exceeds half a meter or some pneumatic butterfly valves need to adjust the internal air pressure frequently, you can clearly feel the miracle of this design.
2. Reduce workspace
In the process of using the pneumatic butterfly valve, the pneumatic butterfly valve always bears the functions of buffering, carrying and lifting, which are "heavy work". When the pneumatic butterfly valve starts to bear pressure without hoop, the internal compressed air will be subject to external pressure. The upper and lower ends are sealed and fixed by the middle end cover. It expands very quickly. The expansion process will cause wear, puncture and damage to the leather bag. The hoop design improves the adaptability of the pneumatic butterfly valve to the factory site to a certain extent. At the same time, compact settings and reduced space waste are more in line with the design requirements.
3. Improve the curve operation ability of pneumatic butterfly valve
In some production work, the curve operation capability of pneumatic butterfly valve is required to be high. The installation of hoop can effectively improve the curve operation ability of pneumatic butterfly valve. The more curves, the stronger the surface handling ability.
4. Extend the service life of pneumatic butterfly valve
Pneumatic butterfly valve is crimped with upper and lower end caps. If the expansion width of the pneumatic butterfly valve is not controlled by the hoop, when the pneumatic butterfly valve is compressed by pressure, the folding degree with the rim will be relatively high. Repeated high folding will accelerate the aging of end cover valve and shorten the service life of pneumatic butterfly valve.
With the change of the national economy from the seller's market to the buyer's market, some deep-seated contradictions, especially the structural contradictions accumulated over the years, have become increasingly prominent. At that time, the unreasonable industrial structure was manifested as follows: excess production capacity of some professions and unreasonable product structure; The skill structure is unreasonable, and the equipment level of the primary industry is low; The arrangement and planning of enterprises are small and scattered, lacking competitive strength and advantages, and the regional structure tends to converge, failing to show comparative advantages and collaboration benefits. Ball valve is a kind of mechanical part that uses elasticity to work. It is generally made of ball valve steel. Its elasticity can be used to control the movement of machine parts, mitigate impact or sensation, store energy, measure the size of force, etc. It is widely used in machines and instruments.
For ball valves, there has been a passive situation of oversupply of low-grade general ball valves and oversupply of high-grade products (high-strength, high stress, heterosexual parts, special materials) for a long time. Now, the output value of the ball valve profession in China has become saturated. According to experts' statistics, the annual production value of ball valves in China has reached 4 billion pieces. There are 21 categories and more than 1600 varieties of ball valve products, mainly including valve ball valve, suspension ball valve, diaphragm ball valve, valve ball valve, hydraulic ball valve, oil pump ball valve, disc ball valve, high-temperature ball valve, circlip, tension spring, torsion spring, compression spring Scroll spring and other ball valves.
