Even if the system design is perfect and the selected equipment is finely crafted, it is inevitable to carry out pneumatic conveying maintenance due to long-term equipment wear or sudden power outages in the powder and granular pneumatic conveying system; In order to facilitate maintenance, maintenance valves, also known as maintenance plug valves or maintenance gate valves, are often equipped in pneumatic conveying systems. Maintenance plug valve is a device used to cut off or roughly control the material flow during the material conveying process. In bag filters, it can generally be used in conjunction with

仓泵出料阀

Warehouse pump discharge valve

Due to the fact that the discharge valve of the bin pump is the outlet for ash transportation, the wear resistance of the valve core or valve plate is the technical key of the discharge valve. According to the wear resistance structure principle of the discharge valve, it is divided into double gate valve and cylindrical discharge valve; Usually, we use pneumatic double gate valves as the discharge valves for the bin pump system. Why do we choose a double gate valve as the discharge valve for the bin pump? The main reason is that other types of valves and sealing surfaces get stuck with loose materials, and loose materials enter the valve chamber, which can quickly cause leakage and wear of the valve; And the gas
