Slurry valve is based on the absorption and digestion of advanced body technology at home and abroad on the valve body structure, sealing form, drive and electrical control made further updates. Product structure is simple, small size, light weight, flow resistance is small, the media is not easy precipitation in the valve body, and easy installation and many other advantages, both with manual, electro-hydraulic operation. Electrical control: travel switch control, position display control, to achieve the machine, electricity, liquid, instrument integration and other multi-functional system. This type of valve in the pipeline should be generally horizontal installation. Structural forms and features: a, the valve body structure and sealing methods The newly developed slurry valve points on the clip and the whole, the clamp-type valve body sealing composite material configuration U-type and T-type composite structure. The integral body seal adopts O-type composite ring structure to overcome the disadvantages of easy displacement and deformation of the original collet type sealant valve with U-shaped gasket force and medium leakage. The gate adopts the knife-shaped structure, which solves the problems such as the mortar seal and seal groove, the lax valve closing and the external leakage. b, the drive sub-manual operation and electro-hydraulic operation of two manual devices: simple operation, suitable for smaller torque valve. Electro-hydraulic device: suitable for large torque, adjustable force and speed, can be arbitrarily locked valve device. Applicable medium: mining, steel industry - for coal slurry, filter ballast and so on. Purification plant - for waste water, mud, dirt and clarified water with suspended solids. Paper industry - for any concentration of pulp, water mixture. Sugar industry - for beet washing, syrup, juice, juice and so on. Food industry - for washing and rinsing equipment, food handling equipment, mash and the like. Power plant ash - for ash slurry.
