Structural features: Manual knife-type gate valve has the advantages of simple and compact structure, reasonable design, light material saving, reliable sealing, light and flexible operation, small size, smooth channel, small flow resistance, light weight, easy installation and disassembly, etc. It can work normally under working pressure of 1.0MPa-1.6MPa and operating temperature of -29-650℃. The gate of the knife-type gate valve has a shearing function, which can scrape off the adhesive on the sealing surface and automatically remove debris. The stainless steel gate can prevent sealing leakage caused by corrosion. This type of valve should generally be installed horizontally in the pipeline.
Installation and use of manual knife-type gate valves
1. Before installation, check the valve cavity and sealing surface, and do not allow dirt or sand to adhere;
2. Bolts at all connection parts must be tightened evenly;
3. Check the packing parts and press them tightly to ensure the sealing of the packing and 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 consistency with the valve requirements;
5. When installing the valve, the user must reserve the necessary space for the valve drive;
6. The wiring of the drive device must be carried out according to the circuit diagram;
