Pneumatic flapper door overview

Pneumatic plug-in door overview: Spiral gate, also known as plug-in valve, has simple structure, flexible operation, light weight and no jamming. It is especially suitable for conveying and flow regulation of various solid materials and block-shaped and pelletized materials of 50mm. The installation is not limited by angle, easy to operate, can be adjusted at any time, can be operated in both directions, simple and flexible. The material is carbon steel, stainless steel, and can be customized according to customer needs of various non-standard spiral gates.

Pneumatic plug-in door product details

Use:

The pneumatic gate valve, plug-in door and gate are widely used in pipelines for dust flow control of building materials, metallurgy, mining and other industries, and are ideal equipment for controlling the flow of dust materials.

Features:

The gate valve has the advantages of simple structure, light weight, flexible operation and convenient assembly and disassembly. The manufacturing of Huaye pipeline equipment is made of high-quality carbon steel, which has high strength, good performance and long service life; the screw and nut adopt soft protective cover structure, Affected by external dust.

working principle:

The gate is mainly composed of a frame, a screw nut, a hand wheel and a shutter. The hand wheel (sprocket) rotates, and the screw rod carries the screw nut and the shutter to reciprocate in a horizontal direction to achieve the purpose of opening and closing the valve.

Manual explanation of the knowledge of the manual door

The manual plug-in valve is also called manual spiral gate valve, and the plug-in door is usually used in the unloading device or the silo. The diameter of the manual screw gate valve is matched with the feeder inlet of the unloader, and there are two kinds of square and round. The installation and connection are convenient. The advantage of this valve is that the valve body has no groove, the medium is not blocked by the medium, and has full-diameter circulation characteristics, which is suitable for use in the pipeline of powder granular medium. The flapper valve sealing structure can be divided into a soft seal and a hard seal structure.

The manual flapper valve has the characteristics of good craftsmanship and compact structure. The sealed valve seat is designed with movable structure, and has anti-wear and automatic compensation functions, so the service life is longer. During the closing and opening process of the flapper valve, the valve seat and the ram are always in close motion, which makes the valve opening and closing force stable and has the characteristics of cutting off the medium. The handwheel can be operated directly to open and close the valve.

The manual flapper valve is the main equipment for the flow conveying control of powder, grain and small pellets. Electric plug-in valves are widely used in metallurgy, mining, building materials, food, chemical and other industries. The gate is equipped with electric, pneumatic and electrohydraulic push rods as the driving device, which is an ideal device for controlling the flow rate and cutting off quickly. The plug-in valve has the advantages of simple and compact structure, reasonable design, reliable sealing, light and flexible operation, small volume, smooth passage, small resistance, easy installation and easy disassembly. It can work normally under high temperature, high dust and strong magnetic environment.
