Introduction:

Hot blast valve is set at the outlet of hot blast stove. During the air supply period, hot blast valve is opened, and the hot blast is sent to hot blast main pipe through hot blast branch pipe. During the shutdown and combustion period, close the hot blast valve to cut off the medium flow.

Main technical features:

1. regarding the common existing problems, such as the lower part of valve disc not being resistant to erosion, leakage of sealing surface, short service life of refractory materials, air leakage of t floating sealing device, and peeling of valve stem coating, adopt multiple patented technologies: full floating sealing of valve stem, full coverage lining of valve body, and asymmetric elliptical water cavity of sealing surface, to comprehensively upgrade the performances.

2. It operates safely and reliably, is easy and efficient to maintain, and has a long service life.
