Pneumatic wear-resistant ceramic disc valve structure features: Pneumatic ceramic disc valve has a unique structure and manufacturing process, the working actuator drives the connecting rod and the driving arm to rotate to drive the disc valve. The sealing surface of the entire disk valve is always close to the sealing seat under the effect of the coil spring. The spring can make the valve flap move vertically to compensate for the thermal expansion and contraction of the valve body and other components, and also to balance the pressure of the pipeline and prevent the small particles Material enters the sealing surface. Valve actuator arm force and sealing seat friction is the valve flap automatically rotates on the sealing surface, so as to polish the sealing surface and shovel the surface deposits. Pneumatic wear-resistant ceramic disc valve is widely used in hard particles, corrosive or slagging medium, high temperature and pressure, frequent movements and other conditions. The main applications are: Pulverized coal transportation, pulverized coal injection, ash discharge system, sewage, waste water treatment system, etc. in the power plant: paper transportation, sewage and wastewater treatment system in the paper industry: catalyst in the chemical industry Conveying system: Industry in the mud delivery system.
