Manual flapper valve works

Electric flapper valve, manual screw valve is usually used in supporting the unloader, manual screw gate diameter and unloader feeding port supporting, square and round two. Brief Description: Suitable for ventilation and dust removal in the metallurgy, building materials, coal, mining, glass, light industry, paper making and other industries, regulation and cutting of solid powder conveying on the wind conveying and exhaust system piping. Flapper valve structure is simple, easy to operate, calcium carbide plant dedicated valve series flapper sliding flexible, sealing performance and other characteristics. Local resistance loss is small, adjust the performance. Details: Nominal pressure: 0.05Mpa Suitable temperature: ≤200 ℃ Suitable medium: grain, grain, powdery material and so on. Diameter: DN200 ~ 800,200 × 200 ~ 800 × 800 Our company set many years experience in the use of flapper valve the most innovative design for metallurgical, building materials, coal, mining, glass, light industry, paper and other industries ventilation dust, Regulation of wind power and exhaust system piping and regulation and shut-off of solid powder conveying. Flapper valve structure is simple, easy to operate, flapper sliding flexibility, sealing performance and so on. Local resistance loss is small, adjust the performance, easy maintenance and disassembly, not easy to deformation, sewage treatment valve to overcome the old series leakage valve leakage, fast deformation, difficult to adjust the problems. Especially suitable for non-viscosity solid powder and less than Φ10mm pellets, crystal material, solid material delivery. Flapper valve, also known as manual knife-type gate valve, knife-shaped gate valve It is a gate and valve seat is always in close contact with the seal of the valve, the principle is to open a gate on the size of the size of the mouth through the gate opening and closing Making the gate on the round mouth with the path to do completely out of line with the action. The advantage of this valve is that there is no groove in the diameter of the valve body, the medium will not jam and clog, and it has the characteristics of full-flow circulation and is suitable for the pipe of powder particle medium. Electric rectangular louver control valve sealing structure can be divided into soft seal, hard seal structure. Thrust knife gate valve is a precision structure, good technology, compact structure and other characteristics of the valve seat structure for the activities of the design, with anti-wear and automatic compensation function, which longer life. In the process of closing and opening the valve seat and the shutter have been close movement, making the valve opening and closing force stability, and has cut off the media and so on. Handwheel configuration can be very direct operation of the hand wheel to open and close the valve.

Biodegradable Cosmetic Packaging

Biodegradable cosmetic packaging refers to packaging materials that are designed to decompose naturally and harmlessly in the environment. These materials are made from natural and renewable resources such as plant-based materials, recycled paper, and bioplastics.

Biodegradable cosmetic packaging is becoming increasingly popular as consumers become more aware of the impact of plastic waste on the environment. Many cosmetic companies are now opting for biodegradable packaging as a way to reduce their carbon footprint and promote sustainability.

Overall, biodegradable cosmetic packaging is a sustainable and eco-friendly option that helps to reduce the impact of plastic waste on the environment.
