Pulverized coal injection, the fixed ball valve discharge characteristics and advantages: 1, manual part can be made of steel or stainless steel casting of joystick. Handle sets limit structure, set in the position of the valve open and close limit, when the valve is used in the key device, the spacing block has a lock can lock on off position to avoid wrong operation. Handle has obviously and off. 2, the valve stem A182F (1 cr13) integral forging processing and modulation, hardness of HB220 ~ 250. Stem through key spline or the parties connected to the handle, strong commonality, easy tear open outfit. Stem with blow-out proof design. 3, valve filling knitting, flexible graphite sealing ring or ptfe seals, lubrication situation of the stem in a reliable seal. 4, according to the needs, the ball valve can be designed as antistatic structure, in the sphere and valve stem, valve stem and valve body between the conductive spring, avoid electrostatic spark to ignite flammable material, ensure the security of the system.喷煤粉、卸灰固定球阀特点。
