First, use 

 This series of manual, pneumatic, hydraulic, electric, electric fan-shaped blind plate valve putting for blast furnace dust and gas into the cooling system, export pipeline, gas medium as a reliable cut off device can also be used for coking plant gas pipeline gas pressure stations and other pipeline. 

 Second, the main performance parameters of the valve 



 Third, the implementation of standards 

 GB6222 industrial enterprises in the gas safety regulations 
 GB9115 steel pipe flanges 
 GB/T13927 ventilation valve pressure test 

 Fourth, the structural characteristics 

 1, with fan-shaped structure, the valve opening and closing as <90 ° of rotation, flexible and easy to open and close quickly from the operation. 
 2, clamping screw by force structure, and good self-locking, sealing will not release the cause media leakage move. 
 3, increasing the water body of the valve, the maximum temperature ≤ 450 ℃, especially for dry dust removal and cooling system. 
 4, with a variety of drive options, pneumatic, hydraulic, electric control of a computer program can be realized. 
 5, the leakage rate: line GB/T13927.
