Description

Technical Field

[0001] The utility model relates to the technical field of drain valves, in particular to a novel drain valve. Background Art

[0002] Drain valves are an indispensable product in the water industry, mainly used in urban, construction, enterprise water supply and drainage projects, industrial and domestic sewage treatment and water conservancy projects. Among them, various types of medium and low pressure valves are widely used, including various types of butterfly valves and gate valves. Others include ball valves, check valves, exhaust valves, plug valves, diaphragm valves, pressure reducing valves, flow regulating valves, mud discharge valves, etc. They are mainly used for liquid discharge or liquid level control.

[0003] The drain valve is installed at the drain outlet of a water storage place such as a pond. When the drain valve is closed, silt and impurities are easily accumulated at the drain outlet of the drain valve. The silt in the later stage will be separated from the valve under the impact of the water flow. However, when the valve is just opened, the water flow rate is low and the blocked impurities and silt cannot be flushed away. Therefore, a new type of drain valve is proposed. Before opening the valve, the blocked silt and impurities are first flushed away, and then the valve is opened. Utility Model Content
