The working principle of manual flashboard valve

Electric flashboard valve, manual spiral gate valve which is equipped on the discharger, the diameter of the manual spiral gate valves with discharger feeding port facilities, a square and round two.

Brief description: applicable to coal, mining, metallurgy, building materials, glass, light industry and papermaking departments ventilation dust removal, pneumatic conveying and the adjustment of the exhaust system pipeline and the adjustment of the solid powder conveying and cut off. Flashboard valve has simple structure, free operating, special valve series board sliding flexible, calcium carbide factory sealed good performance characteristics. Small local resistance loss, regulation performance.

Details:

Nominal pressure: 0.05 Mpa applicable temperature: 200 ¡æ or less applicable medium: grain, grain, powder material, etc. Diameter: DN200 ~ 800200 x 200 ~ 800200 x 800 my company set many years experience of using flashboard valve of the most innovative design, applicable to the metallurgical, coal, mining, building material, glass, light industry and papermaking departments ventilation dust removal, pneumatic conveying and the adjustment of the exhaust system pipeline and the adjustment of the solid powder conveying and cut off. Flashboard valve structure simple, the operation, flexible sliding board, sealed good performance characteristics. Small local resistance loss, good regulation performance, maintenance and disassemble because it is not easy deformation, sewage treatment series valve overcomes the old-fashioned flashboard valve fast air leakage, deformation and difficult adjustment problems. Especially suitable for no viscosity and solid powder less than 10 mm ¦µ particles of solid material, crystal materials, feeding.

Flashboard valve is also called the manual type knife gate valve, knife gate valve is a kind of valve disc always close contact with the valve seat seal, its principle is on the gate open with a size of the size of round mouth, through the gate opening and closing the circular disc are completely out of the mouth with sizes do and consistent action. The advantages of this valve is to the body size without grooves, medium not jam congestion, and all-pass runoff flux characteristics, suitable for the pipe used in powder particles. Electric rectangular shutter regulator its seal structure can be soft seal and hard seal structure. Penetration type knife gate valve is a sophisticated structure, good in usability, the characteristics of compact structure, sealing seat for the structural design of the event, anti wear and automatic compensation function, and longer life. In the process of closing and opening the seat with ram has been close to the movement, the valve opening and closing force is stable, and possesses the characteristics of cutting medium. Configure the handwheel can be directly manipulate the handwheel to open/close the valve.
