Ceramic knife gate valve, also called ceramic knife gate valve, ceramic knife gate valve. Its opening and closing part is a gate, the movement direction of the gate is perpendicular to the direction of the fluid, and the medium is cut by a blade-shaped gate that can cut fiber materials. The ceramic knife gate valve body does not actually have a chamber, the gate rises and falls in the side guide groove, and is pressed against the valve seat by the bottom lug. If a higher medium sealing performance is required, an O-ring seal can be selected. The valve seat realizes bidirectional sealing.
2 Application field editor 1. Mining, iron and steel industry - for coal, filter residue slurry, etc.; 2. Purification device - for waste water, mud, dirt and clarified water with suspended solids; 3. Paper industry - for use For any concentration of pulp, feed water mixture; 4, power station ash removal - for ash slurry.
3 Performance characteristics Editors choose toughened engineering ceramic materials, more wear-resistant!
Engineering ceramic knife gate valve valve sealing parts and vulnerable flow parts are made of toughened engineering ceramic materials; they can withstand the wear and erosion of granular media in high-speed fluids, and the valve has a long service life; the cost performance is 10 times higher than that of ordinary valves.
Apply the national patented lip technology to prevent damage!
The valve seat adopts protective lip technology: the inner diameter of the ceramic sealing ring of the valve seat has a protective lip (patented) structure, which can effectively prevent the hard object from shearing the ceramic sealing ring from the inner diameter when the valve is about to close.
Special structure design, with dual use function!
It is specially designed for medium pipelines under solid-liquid two-phase flow conditions, and is designed with a structural form for the purpose of resisting throttling and scouring, so as to meet the dual use function of shutdown or shutdown + throttling of such medium pipelines.
The valve is light, easy to install and highly adaptable!
The ultra-short structure length saves materials and reduces the overall weight of the pipeline system; it occupies a small effective space, can effectively support the strength of the pipeline, reduce the vibration of the pipeline, and is suitable for installation at any angle on different arranged pipelines.
Diversified driving methods, convenient and fast!
Dingsheng ceramic knife gate valve has electric, manual, electro-hydraulic and manual-hydraulic drive modes. For electric and electro-hydraulic drive valves, remote control and opening indication can be effectively realized. If the valve is throttled or adjusted, the opening can be adjusted remotely. The error can be controlled within 1.0mm, and the self-locking performance is good during operation.
4. Precautions for use Editing the opening and closing parts of the knife gate valve is the gate, and the movement direction of the gate is perpendicular to the direction of the fluid. The knife gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled. The gate has two sealing surfaces. The two sealing surfaces of the most commonly used mode gate valve form a wedge shape. The wedge angle varies with the valve parameters, usually 50. The gate of the wedge type knife gate valve can be made into a whole, called Rigid gate; it can also be made into a gate that can produce a small amount of deformation to improve its craftsmanship and make up for the deviation of the sealing surface angle during processing. This gate is called an elastic gate. When the knife gate valve is closed, the sealing surface It can only rely on the medium pressure to seal, that is, relying on the medium pressure to press the sealing surface of the gate to the valve seat on the other side to ensure the sealing of the sealing surface, which is self-sealing. Most knife gate valves are forced to seal, that is, when the valve is closed, the gate must be forced against the valve seat by external force to ensure the tightness of the sealing surface.
