Butterfly valve advantages and disadvantages

Butterfly valve advantages: 1. Opening and closing convenient, labor-saving, fluid resistance, you can often operate. 2. Simple structure, small size, light weight. 3. Can transport mud, pipe liquid accumulated in the mouth at least. 4. Low pressure, can achieve a good seal. 5. Regulate the performance. Butterfly Disadvantages: 1. The use of pressure and small operating temperature range. 2, poor sealing. Butterfly valve can be divided according to the structure of the bias plate, vertical plate, inclined plate and lever. According to the sealing form can be divided into more sealed and hard seal two. Rubber seals are generally used rubber ring seal, hard seal is usually used metal ring seal. According to the connection type can be divided into flange connection and the clamp connection; According to the transmission can be divided into manual, gear transmission, pneumatic, hydraulic and electric several.

Gold Gravity Concentration Equipment

The STL water-jacketed Gold Concentrator is a kind of gravity separation equipment. It was developed by Changchun Gold Research Institute Co., Ltd. in 1985 and entered the market. At present, it has been used in many domestic and foreign companies. It is suitable for the recovery of single gold in placer gold, vein gold mines and polymetallic mines, instead of mercury plate operations. The addition of large single gold particles in the collected ore before flotation can further increase the recovery rate of gold mines, and it can also be used from gold-bearing mines. Separate single gold from flotation gold-copper concentrate and flotation gold concentrate.

The main indicators of this series of equipment basically reach the level of similar international products (such as Nielsen gold selectors, etc.). Compared with similar equipment at home and abroad, this series of equipment has the advantages of high cost performance, easy operation, and low maintenance costs.
