We all know that the market for new energy commercial vehicles in January was terrible, but how bad was the market and how fierce the market was?

If you hear it, you will be surprised.

Only 31 electric vehicles have dropped by 99.9% from the previous month

31 cars!

This is the data of the production of the certification of pure electric passenger cars of the Ministry of Industry and Information Technology in January. 31 what is the concept? Compared with January last year, it dropped by 98%, which is a drop of 99.9% from December last year! Moreover, this production figure is set back to the level of February 2014. The more you really do, the worse you fall.

And just in the 2016 that just passed, pure electric passenger cars have also achieved quite good production and sales performance. According to the production data of the Ministry of Industry and Information Technology certified by the first commercial vehicle network, the total domestic pure electric buses produced a total of 115,700 vehicles last year. The 88,000 vehicles in the same period last year increased by 31%, setting a new record in the development of new energy buses in China. However, once 2016 was over, the beginning of 2017, the pure electric passenger car market fell into such a dismal situation. It was tempting to note that the policy had no effect on the impact and role of the new energy vehicle, the sunrise industry, but it was unprecedented. Big.

There are three main reasons for analyzing the reasons. The first is a policy change.

Ball valves are straight-through flow valves which provide positive shutoff with minimal pressure drop and flow turbulence. The barrier to flow is a ball which is rotated 90 degrees to the direction of flow. Ball valves are one of the family of quarter turn valves.

Ball valves are durable and usually work to achieve perfect shutoff. They are therefore an excellent choice for shutoff applications. They do not offer the fine control that may be necessary in throttling applications but are sometimes used for this purpose.

Ball valves are used extensively in industry because they are very versatile, and also can be classified in different styles:

By body: Uni-body, split body, Top Entry Ball Valve, and fully welded ball valve.
By port: full port, reduced port, and v port.
By ball/seat: floating ball valve, Trunnion Mounted Ball Valve
By actuators: manual, pneumatic, hydraulic and electric actuated
By pieces: 1-piece, 2-piece and 3-piece
Multi-port valves: three-way ball valve, L-port and T-port, four-way ball valve
