Installation and use of knife gate valve 1. Before installation, check the valve cavity and sealing surface, and no dirt or sand is allowed to adhere; 2. The bolts of each connection part should be tightened evenly; 3. Check that the packing part requires compression, It not only ensures the tightness of the packing, but also ensures the flexible opening of the gate; 4. Before installing the valve, the user must check the valve model, connection size and pay attention to the flow direction of the medium to ensure the consistency with the valve requirements; 5. When installing the valve, the user must The necessary space for valve drive must be reserved; 6. The wiring of the drive device must be carried out according to the circuit diagram; 7. The knife gate valve must be maintained regularly, and must not be bumped and squeezed at will, so as not to affect the sealing. The characteristics of the manual plug-in valve: 1. The manual plug-in valve is often used in conjunction with the unloading device or the silo. The manual screw gate valve adopts flange connection and is easy to install. There are dozens of specifications, widely used in metallurgy, carbon, chemical, building materials and other industries. 2. The manual plug-in valve has the advantages of simple and compact structure, reasonable design, reliable sealing, light and flexible operation, small size, smooth passage, low resistance, easy installation and easy disassembly, etc. The manual screw gate valve can be installed horizontally or vertically. Anti-wear and automatic compensation features long life and so on. 3. During the normal use of the manual plug-in valve, all transmission parts should be checked regularly, and lubricating oil should be added to maintain the electric plug-in valve. Precautions and characteristics in the use of the electric plug-in valve: the opening and closing parts of the plug-in valve are gates. The direction of movement of the gate and the gate is perpendicular to the direction of the fluid, and the gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled. The gate has two sealing surfaces. The two sealing surfaces of the most commonly used mode gate valve form a wedge shape. The wedge angle varies with the valve parameters, usually 50. The gate of the wedge-type plug-in valve can be made into a whole, called Rigid gate; it can also be made into a gate that can produce slight deformation to improve its craftsmanship and make up for the deviation of the sealing surface angle during processing. This gate is called an elastic gate when the plug-in valve is closed, the sealing surface It can only rely on the medium pressure to seal, that is, relying on the medium pressure to press the sealing surface of the gate to the valve seat on the other side to ensure the sealing of the sealing surface, which is self-sealing. Most of the plug-in valves are forced to seal, that is, when the valve is closed, the gate must be forced to the valve seat by external force to ensure the tightness of the sealing surface. The sealing structure of the plug-in valve can be divided into soft sealing structure and hard sealing structure.
