Abstract
The invention discloses a dual-hydraulic-control dual-loop rapid liquid supply valve for columns. The valve comprises valve bodies which are symmetric left and right, wherein the valve body at each side is provided with an independent valve element, liquid supply joint and control port to form a relatively independent liquid supply loop. Liquid inlets in the left valve body and right valve body communicate with each other, liquid return ports communicate with each other, and the valve bodies at the left side and the right side can separately or jointly supply liquid. A motive seal of each valve element adopts a steel seal fit structure. The two conventional rapid liquid supply valve bodies are integrated on one valve, thus the installation space is saved, the pipeline layout is simplified,the cost is greatly lowered, and the universality is better.
