The inner part of Dongfeng electric butterfly valve is filled with inert gas, and the product with elastic function is produced by the piston. The product works without external power, has stable lifting force, and can stretch freely (the electric butterfly valve can be locked and positioned arbitrarily). It is widely used, but the following points should be noted during installation:
1. The air butterfly valve is a high-pressure product, which is strictly and randomly dissected, baked and bumped.
2. The piston rod of the air butterfly valve rotates strictly to the left. If you need to adjust the valve direction, you can only turn it to the right.
3. Ambient temperature for use: - 35 ℃ -+70 ℃. (. Custom made 80 ℃)
4. When installing the connection point, it should rotate flexibly without jamming.
5. The selected size should be reasonable, the force should be appropriate, and the stroke size of the piston rod should have an 8mm margin.
In papermaking, textile and other industries, paper or cloth needs to bypass many transport rollers at a high speed during winding, so constant tension is required during transmission, which can effectively prevent the paper or cloth from loosening, twisting or cracking. In this case, the combination structure of hollow roll and electric butterfly valve can effectively provide constant tension. Moreover, it has strong ability to accept shock loads, and can maintain the transmission installation and transmission parts from damage. This also illustrates that the electric butterfly valve is very suitable for high pressure and small stroke conditions. The use of electric butterfly valve in the bonding process can provide average pressure to ensure the bonding quality. Theoretically, the electric butterfly valve has better cushioning effect than the steel shrink butterfly valve, which can effectively improve the equipment efficiency and extend the service life of the equipment.
Product structure:
The marine is composed of capsule, capsule head and the end of iron sheet.
1. Iron end piece: (divided into A inflation end: installed on the top of the bag for inflation or deflation safety; B sealing end ring: used for processing.
2. Capsule: the cylindrical part of the balloon is the working area of the balloon. Our company designs the best overall winding cord layout according to the size and direction of the main stress of the balloon rolling and the wall, so as to achieve a uniform level of force and maximize performance.
3. Capsule head: the end of the balloon, divided into hemispherical and conical.
For the assembly of many heavy equipment, the installation of traditional heavy equipment relies on cranes for lifting. With the improvement of people's safety awareness and product quality requirements, pneumatic balloons play an irreplaceable role in the assembly or processing of many heavy equipment. On the one hand, there are many blind spots in the whole operation process of crane lifting equipment, which is easy to cause casualties. On the other hand, it is difficult for lifting equipment to avoid collision between lifting parts and main equipment, which is undoubtedly a kind of damage to equipment. Who is willing to put the equipment into operation before losing the control accuracy, leaving a potential safety hazard?
Therefore, in order to improve the control accuracy, the balloon installation method gradually replaced the traditional lifting method, avoiding the blind spot caused by crane operation, and providing a good guarantee for the life safety of on-site operators.
From another point of view, the electric butterfly valve can also play a valve role in lifting equipment, reduce the shaking of equipment during installation, and play a very important role in high-precision installation of equipment.
For the position control capability of electric butterfly valve, the electric butterfly valve has very important characteristics. With the improvement of inflation performance, the axial height elongation of the electric butterfly valve decreases. It can be said that the effect of fine tuning the position is very good.
