Gate valves used in hydropower station are usually in a special working environment, which requires high quality of gate valves.

The common connection mode in hydropower station gate valves is flange connection.Why is flange connection considered the most suitable connection method for gate valves of hydropower station? This connection method is usually two flanges with a number of fastening bolts and nuts, through the compression of the intermediate flange gasket so that the pipe is connected. Flange connection can well withstand the tensile, compressive, torsional, shear strength. Flange connection is a removable joint with convenient disassembly, high connection strength and good tightness.

According to the shape of the joint surface, the flange connection can be divided into smooth type and concavo-convex type. Smooth type for gate valves with low operating pressure. In addition to flange connection, gate valve connection also has thread connection or sleeve connection, which is a relatively simple connection method, which can reliably prevent leakage, etc.
