Product Description

Q647MF pneumatic ash discharge ball valve belongs to the special ball valve for pulverized coal injection is used to control dust and solid powder, especially suitable for blast furnace pulverized coal injection, air pipeline and gun pipeline and other systems. With double stem structure, it can maintain the position accuracy of opening and closing for a long time; The opening and closing torque is small, flexible and lightweight; The actuator has manual, pneumatic, hydraulic, electric, etc., can be remote control or computer program control, one-way sealing and imported shrinkage type structure, especially suitable for coal injection gas solid binomial medium, will not collect ash stuck; Sealing ring, sealing seat, ball using special materials and special technology treatment, wear resistance, long life; The sealing ring is equipped with an automatic wear compensation device, which will not leak due to wear after a period of use.

Product Features

1, the valve seat with wear automatic compensation device, effectively ensure the sealing performance of the valve.
2. The sealing ring made of special materials has the characteristics of high temperature resistance, wear resistance and long service life.
3. The valve stem adopts the whole forging and modulating treatment, the hardness reaches HB220 ~ 250, the valve stem adopts the anti-blowout structure design, and the valve stem can be extended for buried places according to needs;
4. According to customer needs, the ash discharge ball valve can be designed into an anti-static structure, and the conductive spring is set between the ball and the valve stem, the valve stem and the valve body to avoid the electrostatic spark igniting flammable substances and ensure system safety.
5. Various forms of sealing, according to different working conditions can be selected soft sealing structure, hard sealing structure, fire valve seat structure and other structural design.
6. Grease injection auxiliary sealing structure can be set up according to needs, and grease injection valve can be installed in the seat and valve stem, which can be temporarily sealed in emergency.
7. Pneumatic pulverized coal injection special ball valve also has the characteristics of compact structure, flexible opening and closing, convenient installation and maintenance.
