Problems solved by technology

However, the existing flow regulating butterfly valve cannot be used in high temperature environment
When the existing flow regulating butterfly valve is used in a high temperature environment, the inside of the valve body is easily stuck with the valve plate due to high temperature expansion, resulting in product damage and frequent replacement

Abstract

Disclosed is an ultra-high-temperature butterfly valve with a water-cooling structure. Abrasion-resistant and heat-insulation linings are arranged on an inner flow channel of a valve body and the outer surface of a butterfly plate correspondingly, and a valve body cooling water flow channel formed in the valve body and a butterfly plate water-cooling mechanism are used in cooperation, wherein water feeding and water discharging of the butterfly plate water cooling mechanism are conducted through a valve rod, so that water cooling inside the valve body and the butterfly plate is achieved, a valve plate is not likely to be jammed inside the cooled valve body due to high-temperature expansion, a product is protected, and the durability of the product is improved.

Description

technical field [0001] The invention specifically relates to the technical field of high-temperature valves, in particular to an ultra-high-temperature butterfly valve with a water-cooling structure. Background technique [0002] Flow regulating butterfly valves are commonly known as flue gas bypass valves, flue gas shut-off valves, etc., and are widely used in metallurgy, steel, petrochemical, electric power, environmental protection, hot blast stove systems and other industries. Its sealing performance has national standards. For example, the leakage rate needs to meet the national standards. The applicable medium is hot air and flue gas; the operating temperature is less than or equal to 450°C. The flow regulating butterfly valve has the advantages of simple structure, small size, light weight, convenient operation, and good flow regulating function. It is the main executive element in the engineering pipeline system. But the existing flow regulating butterfly valve cann...
