          Description：
          

          A gate valve, an overview:
          PZ973H series The electric clamp knife type valve , equipped with rotary electric device, the valve plate up and down motion, realize remote control valve to open or close the valve body made of cast steel, stainless steel, diameter range: DN50 ~ DN1000, the use of temperature is less than or equal to the nominal pressure: 425 C: 1.0 ~ 1.6MPa. Used in chemical, coal, sugar, water, paper and other fields, especially suitable for papermaking industry to make adjustment and throttle in the pipeline.
          Second, product characteristics:
          1, The electric clamp knife type valve According to the different caliber made dark rod and rod forms (dark bar DN50 ~ 900mm, DN50 ~ 900mm rod), full circle design of the DC channel without slag, block. Processed into the bottom plate blade knife blade, on soft materials such as fiber, pulp, wood pulp with a cutting function, while the role of a good opening and closing. 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. The 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, low price, easy to install, wear and anti blocking measures to perfect and convenient maintenance, convenient use and long service life, and can be arbitrarily selected drive.
          2, valve body, filling culvert are precision casting, the whole body with flange type casting material, according to user needs with 304, 316, 316L, WCB, 2Crl3, PTFE seal with PTFE material, corrosion resistance, abrasion resistance, non stick slag.
          3, the valve plate has 5 support, the valve plate has a good self alignment. When the valve is in the closed state, and under pressure, the valve plate does not shift.
          4, slurry knife gate valves can be supplied with a handwheel, manual zipper, spur gear drive, bevel gear, pneumatic and electric.
          5, slurry knife gate valve can be made within the V shape, triangle, five angle shaped channel. V type gate control can be used as a regulator.
          6, slurry knife gate valve connected in the form of clip, flange lug, metal to metal seal, metal sealing of soft polyurethane, with enhanced PTFE seal.
          7, 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..
          8, the working temperature:
          Soft seal (PTFE):-40 to 180 DEG c;
          Carbon steel: -29 to 425 DEG c;
          Stainless steel: -40 to 600 DEG c;

          Application: widely used in sewage treatment, chemical industry, coal mining industry, paper industry, sugar industry, tap water, paper, steel, construction, food, electricity, medicine, energy systems and other large enterprises discharge pipeline fluid pipeline is connected or cut off device.
          Four, electric clamp knife type gate valve installation:
          1. should be checked before installation the valve cavity and the sealing surface and other parts, there is dirt or sand does not allow attachment;
          2. all bolts evenly tightened requirements;
          3. check the packing requirements of pressed parts, both to ensure the tightness of packing, but also to ensure the gate open and flexible;
          4. user before installing the valve, the valve must be proof model, connect the flow of medium size and attention to ensure consistency with the requirements of the valve;
          5. the user to install the valve, valve driver must reserve the necessary space;
          The connection of the 6. drive circuit diagram shall be carried out;
          7. knife type valve must be regularly maintained, not free to collision and extrusion, so as not to affect the seal.
