Abstract

The invention relates to the technical field of butterfly valves, in particular to a double-valve-plate type triple-eccentric butterfly valve. The double-valve-plate type triple-eccentric butterfly valve comprises two butterfly valves identical in structure. The valve bodies of the two butterfly valves are connected through a box body. A decompression valve is arranged at the bottom of the box body. The two butterfly valves are both provided with electric actuators. The double-valve-plate type triple-eccentric butterfly valve is simple in structure, the electric actuators are interlocked at the far end, and the electric actuators can be synchronously switched on or independently switched on; a discharge valve is arranged in a body cavity, and impurity discharge can be conducted in the one-side switched-on state; and one valve achieves the functions of three valves, and therefore the installation and manufacturing cost is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of butterfly valves, in particular to a double valve plate type triple eccentric butterfly valve. Background technique [0002] At present, a triple-eccentric butterfly valve is installed on the pipeline, and a triple-eccentric butterfly valve needs to be added to the pipeline during pipeline maintenance, which is time-consuming and low in work efficiency. Contents of the invention [0003] The object of the present invention is to overcome the above technical deficiencies, and provide a double valve plate type triple eccentric butterfly valve. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: [0005] A double valve plate type triple eccentric butterfly valve is characterized in that it includes two butterfly valves with the same structure, the valve bodies of the two butterfly valves are connected together through a box body, a pressure relief...
