|South-to-North Water Diversion|
In the fact, the water supply area on the east line of China was densely populated, concentrated in cities, convenient in transportation, and rich in resources. It was an important energy and chemical production base and a major production area for agricultural products such as grain. The potential for economic growth is huge, but the contradiction between water supply and demand has become increasingly prominent. Water shortage has restricted economic and social development and has a serious impact on the ecological environment.
As the core water source for water supply in the Eastern Route region, the Yangtze River has always been the main water source for the Eastern Route Project. It is of good quality and abundant in quantity. The average inflow of seawater for many years has reached more than 900 billion cubic meters and 600 billion cubic meters in special dry years. Provides superior water source conditions.
To this end, the expansion of rivers and lakes, the addition of pumping stations, and the expansion and upgrading of existing pumping stations will be the main content of the hero project. Among them, the Huaiyin Pumping Station in Huai'an City, Jiangsu Province, as the third cascade pumping station of the river-to-north diversion in our province has recently implemented equipment upgrades in response to the "South-to-North Water Diversion" project and to improve water transfer and flood protection functions.
One of the main upgrades is the use of SME Industrial's patented product-the siphon breaking valve. The siphon breaking valve series developed by Mr Li Sunlong, the legal person of SME, is an efficient and automatic safety valve that protects pumps in pumping stations. The pump valve first appeared in 2004. The design of the combination of electrical and mechanical combination used in various large-scale siphon pumping stations is more intelligent and efficient than other traditional pump valves.
As a safe and efficient valve, the siphon breaker valve is mainly installed above the hump (commanding height) of the siphon water delivery pipe and acts as a quick gate on the siphon water outlet pipe. When the main pipeline generates negative pressure and faces the risk of medium backflow, the siphon can be disconnected in time. Prevent the pipeline and water pump from being damaged due to the output siphon when the pump is stopped and the flow is stopped, and the flow is cut off to protect the safety of pipeline equipment.
