Urban drainage system is an engineering facility system for treating and removing urban sewage and rainwater. It is an integral part of urban public facilities. Urban drainage system planning is an integral part of urban master plan. Urban drainage system is usually composed of drainage pipeline and sewage treatment plant. In the case of separate system of sewage and rainwater, the sewage is collected by the drainage pipe and sent to the sewage treatment, and then discharged into the water or recycled.
Drainage valve is an indispensable water industry product in urban drainage system. which is mainly used in urban, construction, enterprise water supply and drainage engineering, industrial and domestic sewage treatment, water conservancy engineering and other fields. Among them, various types of medium and low pressure valves are mainly used, including various butterfly valves and gate valves. Other valves include ball valve, check valve, exhaust valve, plug valve, diaphragm valve, pressure reducing valve, flow regulating valve and sludge discharge valve Etc. The drainage valve can also be used for the drainage of the sewer pipe to effectively control the water level.
Bundor valve, high quality valve suppliers, to provide you with a complete set of urban drainage system valve solutions.
1.When the pipe diameter is not greater than 50mm, the globe valve should be used. When the pipe diameter is greater than 50mm, the gate valve and butterfly valve should be used.
2.need to adjust the flow, water pressure should be used to Control Valve, Globe valve.
3.the requirement of small flow resistance parts (such as water pump suction pipe), appropriate to use gate valve.
4.Gate valves and butterfly valves should be used on the pipe section where the water flow in both directions, and Globe valve should not be used.
5.Butterfly valve and ball valve should be used for parts with small installation space.
6, in the often open and close pipe section, it is appropriate to use the globe valve.
7, large caliber pump outlet pipe should be used on the multi-functional valve.
