Description

Technical Field

[0001] This utility model relates to the field of butterfly valve technology, specifically to a novel clamp-type pneumatic printing and dyeing butterfly valve. Background Technology

[0002] A butterfly valve, also known as a flap valve, is a simple regulating valve that can also be used for on / off control of low-pressure pipeline media. A butterfly valve is a valve whose closing element (valve disc or butterfly plate) is a disc that rotates around its axis to open and close. It primarily functions as a shut-off and throttling device in pipelines. The butterfly valve's opening and closing element is a disc-shaped butterfly plate that rotates around its own axis within the valve body to achieve opening, closing, or regulation. Butterfly valves are suitable for pipelines transporting various corrosive and non-corrosive fluid media in engineering systems such as generators, coal gas, natural gas, liquefied petroleum gas, city gas, hot and cold air, chemical smelting, power generation, and environmental protection, used for regulating and cutting off the flow of media. Currently, various types of butterfly valves are available on the market, but these valves are commonly found to require workers to manually hold the butterfly valve in contact with the pipeline before installation to avoid misalignment, significantly increasing the workload.
