Electric flapper valve is widely used in the pipe flow metallurgy, mining, building materials and other industries dust control materials, is ideal for dust control material flow. Electric-way flat gate structure features: electric gate-way flat steel plate welded structure, counterweight bar self-reset mechanism, compact structure, stable work. Electric flapper valve, electric two-way plate gate of the gate consists of frame, gate and hand electric drive mechanism composed of motor rotation after moderator gate drive for the horizontal reciprocating motion by sprocket achieve the purpose of opening and closing the valve. Gate structure is simple, light weight, flexible operation, easy assembly and disassembly, using high-quality carbon steel, high strength, good performance, long service life; screw and nut with a soft defense shield structure, free from outside influence dust. Electric flapper valve is also called electric screw valve, flapper door electric discharge is usually in supporting the use of electric screw diameter of the unloader valve inlet facilities, there are two kinds of square and round. The advantage of this valve is that the valve body bore no recess, the media will not jam blockage, and having a full bore flow characteristics, powder particle suitable for use in medium pipe. Flapper valve seal sealing structure can be divided into soft and hard seal structure. Electric flapper valve technology is good, compact structure, sealing seat for design activities, anti-wear and automatic compensation function, thus longer life. Flapper valve in the closed and open process, with the gate valve has been close to the sport, making the valve opening and closing force is stable, and has cut off the media and so on. Electric flapper valve is the main equipment powder, grain material, small pellet conveying flow control. Electric flapper valve is widely used in metallurgy, mining, building materials, food, and chemical industries. The gate is equipped with electric, pneumatic, electric hydraulic putter as a drive unit, is to control the flow size, ideal for quickly cutting equipment. Compact electric flapper valve structure, wear a small amount of leakage, a simple, flexible movement, effort, etc., can work normally under high temperature, high dust, magnetic environment. Electric flapper valve use precautions and characteristics: flapper valve opening and closing parts of the gate, the direction of movement of the fluid direction perpendicular to the gate, gate valve can only be fully open and fully closed, can not be adjusted and throttling. Ram has two sealing surface, the two most common mode of sealing surface to form a wedge gate valve, wedge angle with the valve parameters vary, usually 50, wedge gate valve plates can be made into a Overall, called the rigid gate; also be made to produce small quantities of deformation gate in order to improve its process, to make up the sealing surface angle deviations arising during processing, this gate is called the flexible gate flapper valve is closed sealing surface can only rely on media pressure to seal, which rely on the sealing surface of the medium pressure to ram pressure to the other side of the seat to ensure the sealing surface, which is self-sealing. Most flapper valve is sealed by force and when that valve is closed, to rely on external pressure to force the gate valve to ensure the tightness of the sealing surface. Electric flapper valve is the main equipment powder, grain material, small pellet conveying flow control electric flapper valve is widely used in metallurgy, mining, building materials, food, and chemical industries. The gate is equipped with electric, pneumatic, electrical hydraulic putter as a drive unit, is to control the flow size, ideal for quickly cutting compact flapper valve structure, wear, leakage of small amounts, is simple, flexible movement, effort, etc., can in high temperature, high dust, Under normal operating electric magnetic environment flapper valve PN:. 0.05Mpa Temperature: ≤600 ℃ Medium: grains, granules, powder materials, etc. caliber:. DN200 ~ 800,200 × 200 ~ 800 × 800 Botou Friends of a machinery company with years of experience using the most innovative flapper valve design.
