Knife type slurry valve

Knife gate valve, also known as knife gate valve, knife gate gate valve, slurry valve, and mud valve, has a gate as its opening and closing component. The direction of movement of the gate is perpendicular to the direction of the fluid, and the medium is cut off by a blade shaped gate that can cut fiber materials. The gate has two sealing surfaces, and the most commonly used mode is that the two sealing surfaces of the gate valve form a wedge shape. The wedge angle varies with the valve parameters, usually 50. The gate of the wedge knife type gate valve can be made into a whole, called a rigid gate. It can also be made into a gate that can produce slight deformation to improve its processability and compensate for the deviation of the sealing surface angle during the processing. This type of gate is called an elastic gate. The valve body actually does not have a cavity, and the gate rises and falls in the side guide groove, and is tightly pressed onto the valve seat by the bottom lug. If high medium sealing is required, an O-ring sealing valve seat can be selected to achieve bidirectional sealing. Knife gate valves have smaller installation space, low working pressure, and are less likely to accumulate debris, resulting in lower prices.

Installation and Usage Instructions for Knife Gate Valve:

1. Before installing the knife gate valve, the valve chamber and sealing surface must be inspected to ensure that no dirt or sand particles are attached;

2. All connecting bolts should be tightened evenly;

3. The inspection of the filling parts requires compression to ensure both the sealing of the filling and the flexible opening of the ram;

4. Before installing the valve, users must verify 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 valves, users must reserve the necessary space for valve actuation;

6. The wiring of the driving device must be carried out according to the circuit diagram;

7. Knife gate valves must be regularly maintained and must not be collided or squeezed arbitrarily to avoid affecting sealing.

The scope of use of knife gate valves is:

1. Mining, coal washing, steel industry - used for washing coal pipelines, filtration slurry pipelines, and ash discharge pipelines;

2. Purification device - used for wastewater, mud, dirt, and clarified water with suspended solids;

3. Paper industry - used for pulp, feed water mixtures of any concentration;

4. Power plant ash removal - used for ash slurry.

Knife gate valve driving methods: manual, chain wheel, electric, pneumatic, hydraulic, bevel gear, electric hydraulic, and pneumatic driving methods. Knife gate valve appearance: two types: open stem and non rising stem. Knife gate valve materials: cast iron, cast steel, carbon steel, stainless steel, fluorine lined, etc. Knife gate valve sealing: hard sealing, soft sealing, single sided sealing, double sided sealing, and other materials for sealing.The gate has two sealing surfaces, and the gate of the wedge type knife gate valve can be made into a whole, called a rigid gate; To improve its processability and compensate for the deviation in the sealing surface angle during the processing, this type of gate is called an elastic gate. When the knife gate valve is closed, the sealing surface can only rely on medium pressure to seal.

Gate Valve opens shuts is the damper plate, the damper plate heading and the fluid direction is vertical, the gate valve only can do all starts with the entire pass, cannot make the adjustment and the throttle. The damper plate has two packing surfaces, but the most commonly used pattern gate valve two packing surfaces form, the wedge-shaped angle wedge-shaped along with the valve parameter different, usually is 50, medium temperature not Gao Shiwei 2°52'.The wedge type gate valve damper plate may make a whole, the named rigid damper plate; Also may make can produce the micro distortion damper plate, improves its technology capability, the atonement packing surface angle the deviation which produces in the processing process, this kind of damper plate named elastic damper plate.The stainless steel gate valve material quality divides into 304 stainless steel gate valves, 316 stainless steel gate valves, 321 stainless steel gate valves.Expressed the method is: Z41H-16P.
