Description:
A gate is introduced: PZ673X seriesPneumatic knife gate valve in the darkAfter equipped with electromagnetic valve, proximity switches and other accessories to complete the motion control and the output signal of the opening and closing position, also can complete automatic control of continuous action.The main use of cast iron, cast steel, stainless steel etc..The path from DN50 to DN1000.Pneumatic valves are widely used in chemical, coal, sugar, water, paper and other fields, is an ideal sealing valve. Two, PZ673HPneumatic knife gate valve in the darkThe characteristics of: 1. knife gate slurry, dark rod and rod two; single and double sealing structure sealing structure, full circle design of the DC channel without slag, block.Processed into the bottom plate blade knife blade, a sealing ring with plane floating, floating ball arc metal sealing structure, between the gate and the metal seat is gapless hoist, on soft materials such as fiber, pulp, wood pulp with large shearing force and self-cleaning function, but also has good opening and closing function.The upper blades installed in the hard Teflon wiper can prevent dust and scratch gravel and other substances into the packing box, can significantly increase the life of blades. 2. body, filling culvert are precision casting, the whole body with flange type casting, valve plate made of stainless steel and precision processing can obtain ideal sealing effect of grinding and polishing.Compact design, small occupying space, light weight, easy installation, wear-resistant, non stick slag anti blocking measures to perfect and convenient maintenance and long service life. 3., slurry knife gate valve can be made within the V shape, U shape, triangle channel.V type gate control can be used as a regulator, the connection form of clip, flange lug, metal to metal seal, metal sealing of soft polyurethane, PTFE seal. The 4. piston pneumatic actuator, powered by compressed air, an air pressure signal of electric - gas valve positioner or solenoid valve input, the pressure thrust on the piston, and the push rod displacement, to achieve linear motion. 5. medium: gold powder, tailings, pulp, wood pulp, fiber, dust, chemicals, sewage treatment tank, ore, slag, coal, asphalt, outlet, fruit, grain, cement slurry, slaughter wastewater etc..Applicable temperature; soft sealing: (less than 150 DEG C (tetrafluoroethylene), polyurethane is less than or equal to 80 DEG C), seal: less than or equal to 425 DEG C.Working pressure: 0.6 ~ 1.6MPa, nominal diameter: DN40~DN900mm.
