Rural teachers research and development of magnetic levitation valve won five national patents
Recently, Jialian middle school teacher Lu Daming received the notice of the State Patent Office, he developed magnetic levitation valve has won five national patents. Relevant experts believe that the magnetic valve to solve the short life of ordinary valves, easy to drip, there are still drawbacks of safety leftovers. In real life, people encounter a wide range of valves. Most of these valve core cast iron and other metal parts and rubber parts made of combination, due to easy wear and tear, short service life, easy to drip faucet phenomenon, there are still gas leaks left over. Lu Daming, 48, is an art teacher at Yanshan Middle School in Jixian. Inspired by the operation of maglev trains, he started to study magnetic levitation valves in 2001. Magnetic levitation valve uses the magnet's suction force to control the valve opening and closing. The rotating handle can achieve the purpose of opening and closing the valve without connecting with the switch valve body in the valve body, thus fundamentally lifting the problem of wear and leakage of the valve port.
