In the face of so many valve classification and so complex conditions, to choose the most suitable valve for pipeline system installation, we should first understand the characteristics of the valve; Secondly, we should master the steps and basis of valve selection; Furthermore, we should follow the principle of selecting valves for petroleum and chemical industry. The principle of selecting valves in petroleum and chemical industry: the flow passage is straight through valve, which has small flow resistance, and usually is used as cut-off and open medium valve; The valve which is easy to adjust the flow is used to control the flow; Plug valve and ball valve are suitable for reversing and diverting; The valve with wiping function is suitable for medium with suspended particles.

The green development of industry needs innovation. Without innovation, the industry will not progress, and the goal of enterprise development will be difficult to achieve. Green development is not only the need of ecological civilization construction, but also the need of China's development in the new era. The high-quality development of social economy and the improvement of the quality of people's living environment must depend on the industrial progress. If the industrial production mode is relatively backward, such as the problem of dripping and running in the production process, it will produce relatively serious pollution problems, and the development goals of clean production and green industry can not be achieved. In the pharmaceutical industry, if the performance of the

Because the tank wall manhole is located in the lower part of the oil tank, the manhole bears a lot of liquid pressure. In order to prevent leakage, the installation quality of the manhole must be strictly required. The flanges and cover plates are processed with sealing water lines, and care should be taken to protect them during construction to avoid oil leakage during use. Make a mark every time the manhole is removed, so as to avoid dislocations during reinstallation and affect the tightness. When installing the nuts on the manhole cover, apply force evenly in pairs to prevent oil leakage caused by deformation of the cover or uneven force. The tank wall manhole is installed in the lower part of the storage tank, and is mainly used for the staff to enter and exit the storage tan
