Special Ball Valve For Pulverized Coal Injection

The special ball valve for pulverized coal injection produced by Dazhong Valve Group. The valve seat of the ball valve is equipped with an automatic wear compensation device, which can ensure the sealing performance of the ball valve more reliably. Structure, a conductive spring is set between the ball and the valve stem, the valve stem and the valve body to avoid electrostatic ignition and igniting flammable substances and ensure the safety of the system. There are various forms of sealing pairs, and structural designs such as soft sealing structure, hard sealing structure and fire valve seat structure can be selected according to different working conditions.

• The valve seat of the ball valve for pulverized coal injection is equipped with an automatic wear compensation device, which more reliably ensures the sealing performance of the ball valve;

• The sealing ring of the special ball valve for coal injection dust discharge is made of special material, which has the characteristics of high temperature resistance, wear resistance and long service life;

• The valve stem is integrally forged and modulated, with a hardness of HB220～250. The valve stem is designed with an anti-blowout structure. The valve stem can be lengthened for use in buried places according to customer needs; Anti-static structure, a conductive spring is set between the ball and the valve stem, between the valve stem and the valve body, to prevent static ignition from igniting flammable substances and ensure the safety of the system.

• There are various forms of sealing pairs, soft sealing structure, hard sealing structure, fire valve seat structure and other structural designs can be selected according to different working conditions; .As required, a grease injection auxiliary sealing structure can be set, and the valve seat and valve stem part can be designed Add a grease valve, which can be temporarily sealed in an emergency;

• Pulverized coal injection ball valve also has the characteristics of compact valve structure, flexible opening and closing, and convenient installation and maintenance.
