Two-way valve is two-way open, with driving device at both ends of the valve, which is a main control equipment for the flow or conveying quantity of powder, grain, granule and small material, widely used in metallurgy, mining, building materials, grain, chemical industry and other industries to control flow change or cut off quickly.Structural features: two-way plug plate valve is simple in structure, flexible in operation, light in weight and free from stuck resistance, especially suitable for conveying and flow regulation of various solid materials and about 50mm block or lump materials. Two-way plug plate valve is not limited by Angle in installation, easy to operate and can adjust the scale at any time.Suitable medium: no viscosity dust gas, solid powder, small particle material.Manual board valve, electric board valve is welded with carbon steel, widely used in metallurgy, carbon, chemical, building materials and other industries.It is mainly used for flue gas regulation and switching in flue gas pipeline system of flue gas purification system.The gate type gate valve may also divide into: single gate pole type, the double gate type and the elastic gate type;Parallel gate valves can be divided into single gate type and double gate type.According to the thread position of the valve stem, it can be divided into two types: rising stem gate valve and dark stem gate valve.Attention and characteristics in the use of bidirectional disc valve: the gate is the opening and closing part of the disc valve, the movement direction of the gate is perpendicular to the direction of the fluid, the disc valve can only be fully opened and closed, and cannot be adjusted or throttled.The gate has two sealing faces. The two sealing faces of the gate valve in the common mode form a wedge, and the wedge Angle varies with the parameters of the valve, usually 50. The gate of the wedge type gate valve can be formed into a whole, which is called rigid gate.
Two-way flashboard valve also known as two-way spiral gate, is in a one-way spiral gate install a hand wheel drive, the other side has the advantages of simple structure, flexible manipulation, light weight, no jam, opening and closing rapidly, especially suitable for all kinds of solid materials, and around 50 mm block, material conveying and flow control, the installation Angle without limit, easy to operate, can adjust scale, can be a two-way open, simple and practical.With simple structure, flexible operation, light weight and no obstruction, it is especially suitable for conveying and flow regulation of all kinds of solid materials and about 50mm block or lump materials. The installation is not limited by the Angle, easy to operate and can adjust the scale at any time.
