Manual type knife gate valve has simple and compact structure, reasonable design, lightweight materials, sealing is reliable, flexible and convenient operation, small volume, smooth channel, small flow resistance, light weight, easy to install, easy to remove, etc, can work in pressure 1. 0MPa- 2. - 5 mpa, the use of temperature 29 - 650 ℃ cases normal work. Type knife gate valve its gate with shear function, can shave their sticky substance on the surface of the seal, automatic removing debris, stainless steel gate to prevent seal leakage caused by corrosion. This valve shall generally be installed in the pipeline. Knife gate valve type definition: knife gate valve is also called type knife gate valve, knife gate valve, slurry valve, slurry valve, it is the opening and closing of a ram, the ram of the motion direction and perpendicular to the direction of flow on the blade shape ram can cut fiber cutting medium, sealing face has two gate, two of the most commonly used mode gate valve sealing surface form a wedge, the wedge Angle vary with the valve parameters, usually for 5 °, wedge type knife gate Industrial Valves disc can be made into a whole, is called a rigid disc; Can also make it generates trace of deformation of ram, in order to improve the manufacturability, make up for the sealing surface Angle in the process of our processing deviation, this damper is called elastic disc. Type knife gate valve drive mode: manual, chain wheel, electric, pneumatic, hydraulic, bevel gear, electric control hydraulic and hydraulic drive mode, etc. Type knife gate valve shape: stem, non-rising stem two kinds. Type knife gate valve material: cast iron, cast steel, carbon steel, stainless steel liner, fluorine, etc. Type knife gate valve seal: hard seal, soft seal, single seal, double sealed and other sealing material. Type knife gate valve type and classification: PZ73H, PZ73F, PZ73Y manual type knife gate valve, manual drive, clamp connection, rising stem parallel type single ram rigidity, the valve seat sealing surface for carbide, ptfe or processing for the stainless steel body, nominal pressure. 2 pn10 ~ 16, the valve body material is carbon steel ( PZ73H - 10 c / 16 c) , stainless steel, PZ73F - 10 p / 16 p PZ73Y - 10 p / 16) , which has the function of discharge gate valve. Working performance and installation manual type knife gate valve has simple and compact structure, reasonable design, lightweight materials, sealing is reliable, flexible and convenient operation, small volume, smooth channel, small flow resistance, light weight, easy to install, easy to remove, etc, can work in pressure 1. 0MPa- 2. - 5 mpa, the use of temperature 29 - 650 ℃ cases normal work. Type knife gate valve its gate with shear function, can shave their sticky substance on the surface of the seal, automatic removing debris, stainless steel gate to prevent seal leakage caused by corrosion. This valve shall generally be installed in the pipeline. Manual type knife gate valve installation use 1. Before the installation must check valve cavity and seal face and other parts, there is no dirt or sand clinging to the body; 2. Each bolt connection parts, require uniform tight; 3. Check the packing pressure parts requirements, both to ensure that the packing sealing, also to ensure the gate open flexible; 4. Users must before installing the valve, check valve, connected to the flow direction of medium size and note, ensure consistency with the valve requirements; 5. User when installing the valve, the Industrial Valves must be set aside driven necessary space; 6. Drive connection must be according to the circuit diagram; 7. Type knife gate valve must be regularly maintenance, shall not be arbitrarily collision and extrusion, in order to avoid affect the sealing. Manual type knife gate valve, knife gate valve, manual single clip-on type knife gate valve nominal pressure (main performance specification mpa) Shell test ( mpa) Sealing test ( mpa) Applicable medium 1 operating temperature. 0 to 1.
