Description

Discharge valve

Technical Field

The utility model relates to a valve field, concretely relates to discharge valve.

Background

The discharger is also called a discharge valve and consists of a rotor impeller with a plurality of blades, a shell, a sealing element, a speed reducer, a motor and the like. The wear-resistant bearing has the characteristics of reliable and stable operation, low noise, less faults, long service life and the like, and has the advantages of good service performance, high wear resistance and the like by adopting nodular cast iron, bearing steel and the like. As an advanced unloading device, the unloader plays a great role in the industries of dust removal, metallurgy, building materials, chemical industry, food and the like.

The unloader is commonly used in a pneumatic output system, and can uniformly and continuously feed materials to a material conveying pipe for the pressure output system or a negative pressure output system so as to ensure that gas and solid in the pneumatic output pipe are relatively stable, so that pneumatic transmission can normally work, and simultaneously, the unloader can separate the upper and lower air pressure of the unloader to play a role in locking air. When the material in the upper bin falls down by self weight and is filled in the gap between the blades, the material is discharged at the lower part along with the rotation of the blades, so that the discharger can discharge quantitatively and continuously, and is an important part commonly used in a pneumatic conveying system.

The discharger can also be used in a material collecting system as a discharger of a storage bin; the star-shaped discharger is the most advanced discharging device in China, is commonly used in a dust removal system as one of important devices of the dust removal system, is particularly suitable for dust and small-particle materials, and is preferably selected by engineering projects in the industrial industries such as environmental protection, metallurgy, chemical industry, grain, cement, road building, drying equipment and the like.
