Description：
A brief introduction of the gate: PZ43H seriesPlum blossom type manual knife gate valveThe knife type gate has a good shearing, the most suitable fluid in the slurry, powder granules, fibers and other difficult to control, widely used in papermaking, petrochemical, mining, drainage, food and other industries.Knife type valve with a variety of seat options, and can be controlled according to site requirements, equipped with electric or pneumatic actuators, valve automation. Two, structural characteristics: PZ73H seriesPlum blossom type manual knife gate valveIs the gate opening and closing parts, RAM direction of motion perpendicular to the direction of the fluid, valve can only be fully open and fully closed, can not be adjusted and the throttle. There are two gate sealing surface, the most common mode of gate valve sealing surface to form two wedge, the wedge angle varies with the valve parameters, usually 50, wedge type knife gate valve can be made into a whole, called the rigid gate; can also be made to produce micro deformation of ram, in order to improve its process of the deviation, make up the sealing surface angle in the process, the gate is called the flexible gate. Knife gate valve is closed, the sealing surface can only rely on media pressure to seal, that media pressure will depend on the sealing surface of the ram pressure to the other side of the seat to ensure the sealing surface of the seal, which is self sealing.Most of the knife gate valve is sealed by force, that the valve is closed, to rely on external pressure to force the gate to the seat to ensure the sealing surface of the seal. Three,Plum blossom type manual knife gate valveStandard Specification for: Design and manufacturing standards: The structure of standard length: GB/T 12221-2005 Flange standard: GB/T 9113 Pressure temperature rating: GB/T 12224-2005 Test standards: GB/T 13927-2008 Four,Plum blossom type manual knife gate valveThe main technical indicators: PZ43H knife gate valve (quincunx); Design and manufacture: JB/T8691-1998; Length: GB/T15188.2-94; Flange: GB/T9113.1-2000 JB/T79-94; Test and inspection: GB/T13927-92; Valve cover: carbon steel, stainless steel; Ram: stainless steel; Valve shaft: 301 stainless iron, stainless steel; Seal ring: rubber, PTFE, stainless steel, hard alloy; Nominal pressure: 0.6MPa, 1.0MPa, 1.6MPa, 2.5MPa, 150Lb; The casing seal test: 1.1XPN test: 1.5XPN; Nominal diameter: DN50 ~ 1000mmNPS2 ~ 40 ""; Working temperature: rubber seal 80 PTFE seal is less than or equal to 180 DEG C, C, C = 425 seal; Suitable temperature: -38 ~ 650 + C (specific temperature range as the sealing material and the properties of the media set); Flange: ANSIB16.5, GB / T9113, JB / T79, HG, SH, JIS, DIN, NF, BS; Main material: WCB, ZG1Cr18Ni9Ti, ZG1Cr18Ni12Mo2Ti, CF8, CF8M, CF3, CF3M; Seal type: hard seal, soft seal; Leakage: Seal: D (liquid level 0.1 * DNmm3 / s): a soft seal (zero leakage); Accessories: mounting flange; Suitable medium: syrup, pulp, sewage, coal ash, slag and water mixture medium etc.. Five,Plum blossom type manual knife gate valveMatters needing attention： 1, the installation must be inspected before 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, the 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; 6 wire drive device shall be carried out according to a circuit diagram; 7, knife type valve must be regularly maintained, not free to collision and extrusion, so as not to affect the seal.
