Intelligent instrument is a pipeline valve attachment. It is used to change the channel section and flow direction of medium, control of a device for conveying medium flow. Sealing performance valve is instrument instrument valve part of the sealing ability to prevent media leaks, it is the most important technical performance indicators instrument valve. Sealing instrument valve has three parts: opening and closing parts and contact the valve seat sealing surface between the two; stem and stuffing box packing and distribution and office; valve connection with the valve cover. The first one is called the leak within the leak, also known as Guan lax, it will affect the ability of instrument valve cut off the media. For the truncated valve, the internal leakage is not allowed. Leakage after the two called the leakage, that media leaks from the valve to the valve. Leakage will result in material loss, pollution of the environment, it will result in serious accidents. For flammable and explosive, toxic or radioactive medium, leakage is not allowed, so the valve must have a reliable sealing performance. Shanghai Ming Bao valve

Intelligent valve instrument is the combination of computer science, electronics, digital signal processing, artificial intelligence and other emerging technologies with traditional instrumentation technology. Intelligent instrument allows two-way communication, can record the detailed data, collected and stored data, the connection with other devices. However, with the development of economy and social progress, the application of intelligent instrument is more and more popular. Intelligent instrument will play a particularly important role in many fields, with the role of the show, now get the popularity of intelligent instrument. Intelligent instrument has also led the development of downstream industries.

Vigorously develop the smart grid, and the government's support vigorously, its development to create a good environment. Smart grid for the national Twelfth Five-Year Plan period of the network industry in the development of the ten major application areas, has become the focus of the provincial and local network 3-5 years of development planning.

Intelligent instrument valves will become popular in recent years, especially the intelligent measurement and control instruments. There are some shortcomings in volume, function, power and other traditional instruments, and intelligent instrument valve is a good solution to these problems, therefore the application range is more extensive.
