Most type knife gate valve used in some difficult to control the fluid pipe, such as sewage, chemical, coal, paper, etc, are equipped with electric or pneumatic actuators to realize the automation of the valve, knife gate valve is in the direction of flow direction and the vertical damper as an opening and closing a gate valve, cut off the medium effect is good, especially suitable for papermaking industry used on the pipeline to adjust and throttling. Type knife gate valve disc has practical operation convenient and free open, flexible and reliable, but in the process of type knife gate valve is installed, must do the following to prevent harmful effect on the product: 1, the belt transmission mechanism of the gate, according to the regulations of the product instruction manual installation. 2, double disc gate valves should be installed vertically ( The stem in a vertical position, the handwheel at the top) 。 3, pay attention to keep clean in areas such as the valve cavity and seal face, avoid dirt or grains of sand in the attached attachment for installation; 4, set aside the valve drive space is necessary, in order to convenient operation; 5, if using automated driving devices, need to check whether the drive of the wiring connections to the circuit diagram; 6, check whether the bolt connection part evenly tighten, to ensure that the valve pipe under the impact of the dielectric loss; 7, check the packing valve parts, compact, to ensure the sealing of the packing and the opening of the gate is flexibility; 8, model, connected to the flow direction of medium size and check valve, to ensure that the requirements consistent with the valve pipe; 10, hand wheel, lever and the transmission mechanism are not allowed to make a lifting, and it is forbidden to collision. If often switch to use type knife gate valve, lubrication at least once a month, should be regularly to maintenance of the valve, avoid valve by collision and extrusion, in order to ensure the valve sealing.
