Dark plate manual knife gate valve - dark bar type knife gate valve

A brief introduction of the gate:
PZ73X series Manual dark plate knife type gate valve, slurry valve rod dark Gas knife gate valve with knife type gate, has a good shearing blocking function, the most suitable fluid in the slurry, powder granules, fibers, slurry, mud slurry, sewage treatment and other difficult to control, widely used in sewage treatment, chemical industry, coal mining industry, paper industry, sugar industry, tap water, paper, steel, building food, electricity, medicine, energy systems and other large enterprises discharge pipeline fluid pipeline is connected or cut off device.
Second, working principle:
PZ73X series Manual dark plate knife type gate valve, slurry valve rod dark Gas knife gate valve as a gate valve, gate valve working principle with some similar, are on the gate of the lift to complete the opening and closing of the valve. Ram direction of motion perpendicular to the direction of the fluid, by the blade shaped gate can cutting fiber material to cut off the media. Body PZ73TC dark plate series manual knife type gate valve, slurry valve, gas dark rod type knife gate valve does not actually exist in the chamber, the gate side of the guide groove and the lifting lug bottom pressed on the seat, to achieve high medium sealing, can choose O sealing valve seat to achieve two-way seal.
Three, basic characteristics:
1, has the good function of shear;
The gate 2, rise of the sealing surface, can scrape the surface of the adhesive seal material, automatic removal of debris;
3, stainless steel gate to prevent corrosion;
4, short length of the structure, can save material and installation space, can effectively support the strength of the pipeline.

Six, Manual dark plate knife type gate valve, slurry valve rod dark Note, gas switch:
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.
