Introduction to the valve legend:
The valve legend (valve graphical symbol) is a graphical representation of the valve in a simple graphic depiction. The valve legend plays a schematic and standard role. In general, the valve legend is not much different, but there will be some regional differences. The valve legend includes a legend for each type of valve, which also contains symbol information for various commonly used valves such as ball valves, butterfly valves, gate valves, and globe valves. In the professional drawing of water supply and drainage, the valve legend is an important reference. Different types of valve symbols are different. To help you master the symbolic representation of each valve, the following is a summary of the valve legend for everyone to review.

Note: The valve legend should be represented by a pattern, and the drawing should not be replaced by words. In the drawing process, if the valve used by the same valve symbol is used differently, it can be represented by the uppercase English name in the lower right corner of the figure. If a part must be explained, the description should be easy to understand, concise and clear. Questions about the entire project should be explained on the front page, and partial questions should be noted in this drawing.
