Ma Shuo, vice president of the World Maritime University, said that Shanghai is now building an international shipping center, and the relevant senior professionals are in short supply. Therefore, the masters of “International Transportation and Logistics†trained by them are very popular among enterprises after graduation. With a master's degree in the same discipline as the University of the World Maritime University and a good employment environment, this master's program has begun to attract more and more foreign students. Compared with the Swedish headquarters, the diploma is the same as the quality of the teaching, but the cost is much less. He also told the author that the Swedish University Headquarters of the World Maritime University is recruiting students from around the world. The master's degree is only about 120 per year. Considering the market demand and the importance of China's status in the world shipping industry, the Shanghai class recruits more than 40 masters each year. A quarter of the total number of masters of the World Maritime University.
The president of the World Maritime University, Robertstein, said that the Shanghai students of the major accounted for a quarter of the total number of masters of the World Maritime University. In addition to Shanghai Maritime University in China, universities in India, Egypt, Chile and other countries have also applied to the World Maritime University for cooperation in organizing “International Transportation and Logistics†projects, but ultimately chose Shanghai Maritime University because Shanghai will build international shipping. The role of the center in the world shipping industry is becoming more and more important.
Check Valve, clack valve, non-return valve or one-way valve is a valve that normally allows fluid (liquid or gas) to flow through it in only one direction.
Check valves are two-port valves, meaning they have two openings in the body, one for fluid to enter and the other for fluid to leave. There are various types of check valves used in a wide variety of applications. Check valves are often part of common household items. Although they are available in a wide range of sizes and costs, check valves generally are very small, simple, or inexpensive. Check valves work automatically and most are not controlled by a person or any external control; accordingly, most do not have any valve handle or stem. The bodies (external shells) of most check valves are made of plastic or metal.
An important concept in check valves is the cracking pressure which is the minimum upstream pressure at which the valve will operate. Typically the check valve is designed for and can therefore be specified for a specific cracking pressure.
Heart valves are essentially inlet and outlet check valves for the heart ventricles, since the ventricles act as pumps.
