The ball-type sealing capacity of the feeder of anode jacking frame mainly includes the cylinder, the support rod, the hollow support rod, the feeding valve, the anti-blowing device, the upper rod, the discharging rod, the discharge valve, the measuring cylinder and the flange, the cylinder is mounted on the flange, the measuring rod is connected with the piston rod of the cylinder through the support rod, the upper rod is connected with the feeding valve, the feeding valve is connected with the discharging rod, characterized in that the feed valve is spherical and can be used upside down. Close fixed cylinder inlet and reduce abrasion, to make sure accurate discharging and none material leakage after abrasion, when upper rod and fixed volume container are in different shafts. The cylinder piston and the piston rod of front cover can be set with a reset closing device - spring. When the engine is shut down, the piston of the cylinder rises to the upper position, and the piston rod close discharged valve through the upper rod and discharging rod, to make sure no material leakage. The upper end of the piston rod has adjustable cushion plunger, gradually reduce the outlet section, in order to achieve buffer. The piston rod can be fitted with a slip sleeve and / or the lower end of the piston with a limit set to protect the piston rod and cylinder, to extend the service life. There can be a sliding positioning plate near feed valve cooperated with the support rod and the hollow support rod, to reduce the different axes of the feed valve and the discharge valve. The discharge valve and the discharging rod can be articulated with a crosshead universal joint to ensure that the discharge valve and the bottom of the quantitative cylinder closed. The discharge valve and the quantitative cylinder contact seal is spherical, close fixed cylinder outlet and reduce abrasion when discharging rod and fixed volume container are in different shafts, in order to ensure less abrasion and none material leakage. The invention has the advantages that the hopper does not continue to discharge or leak material due to the leakage of the pipeline, the insufficient air pressure and air volume or the stopped gas condition; ensures that the spring does not scratch the piston rod and the cylinder; There can be a sliding positioning plate near feed valve cooperated with feed valve and the discharge valve, thus the seal is tight and abrasion is small; the quantitative cylinder contact surface will not deform due to collision because of this design, the service life is doubled; discharging accuracy ≤ ± 0.5%.
