In the field of pneumatic butterfly valves, priority entities are bound to gain a certain opportunity to participate in market competition, and will also be rewarded handsomely in the market. As the core component of automobile valves, the performance of pneumatic butterfly valves directly affects the comfort of automobiles and the damage to roads, The production technology development direction of the balloon valve will also keep pace with it - towards the direction of strong performance, long service life, safety and reliability of the valve
China's automobile industry has passed. With the rapid development in the past 10 years, both the technical content, manufacturing level and output have been greatly improved. However, looking at the comprehensive strength of the entire Chinese automobile industry, we are also very clear and developed. There is still a big gap. Compared with us, we are still affected by the whole vehicle production technology and cannot generally equip cars, large buses and trucks with pneumatic butterfly valves
This development trend has also clearly indicated that the research and application of pneumatic butterfly valve in the formulation of new materials and its vulcanization process must go beyond the tradition, implement innovation, and implement independent intellectual property rights
Pneumatic butterfly valve is a flexible body formed by vulcanization of cord layer, inner and outer layers or steel wire ring after molding, which uses the compressibility of air to realize elastic function. It is commonly known as pneumatic butterfly valve, pneumatic butterfly valve, etc.
Classification of pneumatic butterfly valve products:
Pneumatic butterfly valves can be divided into three categories according to their shapes: capsule type, membrane type and sleeve type. According to the sealing structure, it can be divided into four categories: pressure self sealing type, rim clamping type, hoop sealing type and hybrid type. The load of the pneumatic butterfly valve is mainly borne by the cord. The number of layers of the cord is mainly composed of two layers. The product is required to be composed of four layers of cord. The inner layer mainly plays a sealing role, while the outer layer plays a protective role as well as a sealing role.
Function of pneumatic butterfly valve:
After the pneumatic butterfly valve is assembled, compressed air is filled into the pneumatic butterfly valve. The compressibility of the air is used to realize the elastic effect. It is a non-metallic ball valve with the function of a ball valve. At the same time, the pneumatic butterfly valve has many advantages over the metal ball valve; The stiffness of the pneumatic butterfly valve changes with the load, which makes the ball valve device have an ideal performance: the pneumatic butterfly valve can bear axial and radial loads at the same time, and can also transmit torque; the pneumatic butterfly valve can obtain different bearing capacity by adjusting the internal pressure, so it can meet the needs of a variety of loads: the pneumatic butterfly valve has light weight and long service life; the pneumatic butterfly valve has good high-frequency vibration isolation and sound insulation functions. The pneumatic butterfly valve requires small installation space and is easy to replace.
