Where did the money go?
Summer is a lot of fruit harvest season, this year the rain is a good whole, the fruit is a good harvest, but for fruit farmers, the harvest is not necessarily a harvest, the recent national media reports: the nectarines in Shaanxi, Shandong, Jiangsu and other watermelon rotten, Guangdong's pitaya inverted ponds, Guangxi, Hainan, banana, litchi, litchi. The half price of the past year was no one. The news that fruit bumper harvest does not harvest is basically all the year, the reason is also a lot, some are because of the fruit production, too concentrated on the market, some of the fruit quality is not good, some are high cost of transportation cost middle link and so on. But from the basic principles of market economics, it is an important reason why people's consumption capacity is insufficient.

Analysis on the problems existing in China's valve industry in 2014
At present, there are still some problems in China's valve industry. For example, China's valve enterprises are mainly low-level, small-scale and family workshop type enterprises. In terms of products, due to repeated investment and insufficient technology import, the leading products of China's valve enterprises are still low-quality mass products. It is understood that at present, all kinds of valves produced by enterprises in our country have some disadvantages, such as leakage, leakage, low appearance quality, short life, inflexible operation, and unreliability of valve electric device and pneumatic device. Some products are only equivalent to the international level in the early 80s of last century, some of the high temperature, high pressure and key equipment needed Valves are still dependent on imports

Common failures and preventive measures for automatic valves
Fault one: the valve is not through. The reasons are as follows: (1) the control channel is blocked by the sundries (the passage is small and easy to be blocked); and the piston is stuck in the highest position because of rust stains; although the upper part is stressed, it can not move down and can not open the main channel. Therefore, before the piston pressure relief valve must be installed filters, for newly installed or long-term discontinued pressure relief valve, must be disassembled for inspection and cleaning.
