一.Product Introduction
The special slag-locking valve for coal chemical industry has attracted much attention from the industry because of its critical location, high technical requirements and expensive cost. It can be used under very harsh working conditions.Coal chemical industry and coal-to-oil projects must first be coal gasified. The slag-locking valve of the coal gasification device is used for the discharge of cinder after coal gasification. The conditions of the coal gasification device are very demanding. Coal-to-oil, coal-to-oil, coal gasification and other coal chemical projects have very strict requirements for valves, which require valves to have functions such as high wear resistance and scouring resistance, anti-fouling, anti-scarring, and rapid cutting.Due to the high requirements of working conditions, the technical requirements for valves for coal chemical industry are very difficult.
