New dynamic sealing technology of electric ball valve
With the progress of the times, gas control products used by gas companies are changing with each passing day, and remote control payment systems and smart card prepayment systems are the two main methods. The valves used in these two systems are mainly electric ball valves. They are characterized by extremely low pressure loss, easy operation of on/off valves, low power consumption and easy control. They are one of the preferred valve designs for mechanical electronic engineering designers. In terms of safety and stability, gas valves have high standards, and the main factor influencing its safety is dynamic sealing. Most of the dynamic sealing of the electric ball valve is at the rotating shaft, and most of the design of the dynamic seal is now a contact seal. This type of material has the advantages of easy material wear, low reliability, low transmission rate, narrow transmission range, and poor sealing performance. Disadvantages. Magnetic fluid sealing technology is a new type of dynamic sealing technology for electric ball valves. It belongs to non-contact dynamic sealing and can correct the above shortcomings and meet the standard of the gas valve functional part.
Magnetic fluid is one of the most advanced nanotechnology at home and abroad. It has the following characteristics: It generates magnetic force under the action of an external magnetic field and generates internal volume force, and the strength will increase with the increase of external magnetic field, until it is saturated; it has liquid form. The flow properties, with the help of an external magnetic field, allow the magnetic fluid to flow freely to any position; it has the same effects as normal nanoparticles.
The use of magnetic liquid sealing technology in electric ball valve is accomplished by virtue of the magnetic fluid itself has the characteristics in the magnetic field, the characteristics of magnetic liquid sealing technology: high sealing performance, not easy to leak; transmission efficiency is high , up to 99%, almost no power loss; high reliability; long service life; high flexibility; wide range of output torque, therefore, magnetic fluid sealing technology should be an ideal technology for dynamic sealing.
If the sealing of the electric ball valve adopts the sealing technology of the magnetic liquid, then it can obviously improve its mechanical efficiency, improve the sealing performance and enhance the reliability, and also reduce the processing difficulty and increase its production efficiency. Nowadays, the magnetic liquid sealing technology also has disadvantages such as the inconvenience of the liquid medium and the high production cost. These shortcomings limit its use on a large scale. However, once these disadvantages are improved, the dynamic sealing technology of magnetic fluids will surely occupy a dominant position in the dynamic sealing technology in various fields.
