BRAY Knife Valve from the United StatesProduct Introduction

Knife gate valve, also known as knife gate valve, knife gate valve, slurry valve, mud valve, its opening and closing component is the gate plate. The movement direction of the gate plate is perpendicular to the direction of the fluid, and the medium is cut off by a blade shaped gate plate that can cut fiber materials. The gate plate has two sealing surfaces, and the two sealing surfaces of the commonly used mode gate plate valve form a wedge shape. The wedge angle varies with the valve parameters, usually 5 °. The gate plate of the wedge knife gate valve can be made as a whole, called a rigid gate plate; 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 chamber, and the gate plate rises and falls in the side guide groove, and is tightly pressed against the valve seat by the bottom protrusion. If high medium sealing performance is required, an O-shaped sealing valve seat can be used to achieve bidirectional sealing. Knife gate valve has a small installation space, low working pressure, is not easy to accumulate debris, and is relatively low in price.

When the knife type gate valve is closed, the sealing surface can be sealed solely by the medium pressure, that is, the sealing surface of the gate is pressed against the valve seat on the other side by the medium pressure to ensure the sealing surface is sealed, which is called self sealing Most gate valves use forced sealing, which means that when the valve is closed, external force must be used to forcefully press the gate plate against the valve seat to ensure the sealing performance of the sealing surface. This type of valve should generally be installed vertically in pipelines.

Knife gate valve drive modes: manual, chain wheel, electric, pneumatic, hydraulic, bevel gear, electrically controlled hydraulic, and pneumatic hydraulic. Knife type gate valve appearance: two types: open stem and concealed stem. Knife gate valve materials: cast iron, cast steel, carbon steel, stainless steel, fluorine lining, etc. Knife gate valve sealing: hard sealing, soft sealing, single-sided sealing, double-sided sealing and other materials for sealing.

The ultra-thin knife gate valve solves the difficult problems of high flow resistance, heavy weight, difficult installation, and large footprint of ordinary gate valves, flat gate valves, ball valves, globe valves, regulating valves, butterfly valves, and other types of valves due to its advantages of small volume, low flow resistance, light weight, easy installation, and easy disassembly. After the emergence of knife gate valves, a large number of general-purpose cut-off valves and regulating valves have been replaced by them. Until now, the United States and Japan have the largest usage of knife gate valves.
The scope of use of knife gate valve is:

1. Mining, coal washing, and steel industry - used for washing coal pipelines, slag 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 any concentration of pulp, feed water mixture;

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