Product Description

Industrial double flap valve for ash discharge

316L Stainless Steel Double Flap Valve with Pneumatic  
The valve plate is automatically opened under the gravity of the material. After the material falls, the counterweight lever system automatically resets the valve plate to prevent the wild wind from blowing in, thereby completing the material transportation. There are mainly single and double door flap valves. The double flap valve mainly uses the switches at different times of the upper and lower valves to keep the middle of the device in a closed state to prevent air turbulence. If it is under positive pressure delivery, the pneumatic double lock valve can also act as a balancing and booster valve to assist the flow, so that the device can continuously pulsate the feed and at the same time has the function of gas lock to meet the force. The requirements for conveying powdered material.

Double weight hammer flap valve

Double-layer hammer flap valve adopts mechanical transmission, smooth transmission, no impact, no fault, fewer replacement parts and reliable use. The valve is divided into upper and lower layers. When working, the upper valve is opened by a mechanical transmission, and the upper valve is closed by the balance weight. Then, the lower valve is opened by the mechanical transmission, and the lower valve is closed by the balance weight, so that one unloading cycle is completed. The double-layer ash discharge valve is an ideal ash discharge valve in metallurgy, non-ferrous and environmental protection dust removal equipment. Heavy hammer flap valve is widely used in building materials, metallurgy, chemical industry, electric power and other industries. The heavy hammer flap valve is used as a hopper unloading device for various types of equipment and a unloading device for various grinding machines, dryers, silos and other equipment to prevent wild wind blowing.

working principle:
The single and double-layer lock air valves mainly use the switches at different times of the upper and lower valves to keep the middle of the equipment in a state where the valve plate is always closed and blocked to prevent air turbulence. If it is under positive pressure delivery, the pneumatic double lock valve can also act as a balancing and booster valve to assist the flow, so that the device can continuously pulsate the feed and at the same time has the function of gas lock to meet the force. The requirements for conveying powdered material.
The cement industry is also a lock-in and ash-discharge device for various mills, dryers, silos, silos and closed conveyor systems. The valve is an automatic reset mechanism for the material to open and close automatically under the action of gravity. The hammer has the advantages of stable rotation, energy saving, adjustable discharge capacity, reliable performance of unloading ash and gas lock. There are two kinds of single-door and double-door structure. The single-door double-layer flap valve has good sealing performance; the double door double-layer flap valve has a large amount of ash discharge.

Features:
1, the overall structure of the design is strong and compact, stable and reliable, delicate and beautiful, simple structure, easy maintenance;
2, valve plate and valve seat alternately switch, no sliding structure, strong sealing performance, flange shape can be round or square;
3, can pneumatically convey the powder material system, can also be used for the general pulsating discharge occasion with pressure difference;
4, good wear resistance, suitable for sealing under high temperature, not easy to produce blocking phenomenon;
5, according to the actual need to choose a variety of main material: stainless steel (SS304, SS304L, SS316, 316L, SS836L) carbon steel;
6, polishing accuracy up to 300 #, suitable for conveying food grade materials, there are a variety of drive methods can choose: pneumatic, electric;
