Manual dark BanDao type gate valves - non-rising stem knife gate valve

One, the gate valve's brief introduction:
PZ73X series manual dark BanDao gate, non-rising stem type slurry type USES the knife gate valve, gas knife gate valve gate, has good shear by the role, the most suitable for paste, powder materials, fiber, grout, sａnd slurry, sewage treatment, such as difficult to control the fluid flow, widely used in wastewater treatment, chemical industry, mining, paper industry, the sugar industry, water, paper making, steel, construction, food, electricity, medicine, energy systems and other large enterprises discharge pipeline fluid pipe used as connected or blocking device.
Second, the working principle:
PZ73X series manual dark BanDao gate, non-rising stem type plasma knife gate valve gate valve, gas as a kind of gate valve, the working principle of gate valves with some similar, is done by lifting of the gate opening and closing of the valve.Direction and perpendicular to the direction of flow of the gate on the blade shape ram can cut fiber cut off the medium.PZ73TC series manual dark BanDao gate, non-rising stem type plasma knife gate valve gate valve, gas chamber body actually does not exist, ram in side guide groove inside the elevator, and by the lugs at the bottom of the press on the seat, if you need to achieve high sealing medium, o-type sealing seat can be used to realize two-way sealing.
Three, the basic features:
1, good shear function;
2, as well as rise of disc sealing surface, can shave their sticky on the surface of the sealing, automatic removing debris;
3, stainless steel gate to prevent corrosion;
4, the structure length is short, can save raw materials and installation space, also effectively support the strength of pipeline.

Six, manual dark BanDao gate valve gate, non-rising stem type pulp breaker, gas, the matters needing attention:
1, before 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 valve must be set aside to drive the necessary space;
6, wiring shall be according to the circuit diagram of the driving device;
7, knife gate valve must be regularly maintenance, shall not be arbitrarily collision and extrusion, in order to avoid affect the sealing.
