The worm wheel butterfly valve has a simple structure, small volume, and light weight, and is only composed of a few parts. Moreover, the valve can be quickly opened and closed by rotating it 90 °, with simple operation and excellent fluid control characteristics. When the flange butterfly valve is in the fully open position, there are two sealing types of butterfly valves: elastic sealing and metal sealing. Elastic sealing valve, the sealing ring can be embedded on the valve body or attached to the periphery of the butterfly plate.

 

If a butterfly valve is required for flow control, the main thing is to choose the correct size and type of valve. The structural principle of butterfly valves is particularly suitable for making large-diameter valves. Butterfly valves are not only widely used in general industries such as petroleum, gas, chemical, and water treatment, but also in cooling water systems of thermal power plants.

 

There are two commonly used butterfly valves: wafer type butterfly valve and flange type butterfly valve. A wafer type butterfly valve is a valve that is connected between two pipeline flanges using double headed bolts. A flange type butterfly valve is a valve with a flange, and the flanges at both ends of the valve are connected to the pipeline flange using bolts.

 

When in the fully open position, the thickness of the butterfly plate is the only resistance when the medium flows through the valve body, so the pressure drop generated through the valve is very small, so it has good flow control characteristics. Butterfly valves have two types of sealing: elastic sealing and metal sealing. Elastic sealing valve, the sealing ring can be embedded on the valve body or attached to the periphery of the butterfly plate.

 

 

1. The design is novel and reasonable, the structure is perfect, the weight is light, and the opening and closing are quick.

2. The operating torque is small, the operation is convenient, labor-saving and dexterous.

3. It can be installed in any position and easy to maintain.

4. The seal can be replaced, and the sealing performance is reliable to achieve two-way sealing and zero leakage.

5. The sealing material has the characteristics of aging resistance, weak corrosion resistance and long service life.

 

 

1. The opening and closing is convenient and quick, labor-saving, and the fluid resistance is small, so it can be operated frequently.

2. Simple structure, small size and light weight.

3. It can transport mud, and there is less liquid accumulated at the mouth of the pipeline.

4. Under low pressure, good sealing can be achieved.

5. Good adjustment performance.
