Sand Casting of Carbon Steel Butterfly Valve

Sand Casting of Carbon Steel Butterfly Valve

The butterfly valve is suitable for flow regulation. Since the pressure loss of the butterfly valve in the pipe is relatively large, about three times that of the gate valve, when selecting the butterfly valve, the influence of the pressure loss of the pipeline system should be fully considered

Product Detail:

The butterfly valve is suitable for flow regulation. Since the pressure loss of the butterfly valve in the pipe is relatively large, about three times that of the gate valve, when selecting the butterfly valve, the influence of the pressure loss of the pipeline system should be fully considered, and the strength of the disk medium subjected to the pressure of the pipeline when closing should also be considered. In addition, the limits of the operating temperature of the elastomeric seat material at elevated temperatures must also be considered.

Valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metals, and radioactive media. Mainly cut and throttle on the pipeline. The butterfly valve opening and closing member is a disc-shaped butterfly plate that rotates around its own axis in the valve body to achieve the purpose of opening and closing or adjusting.


Process introduction

Ordinary casting coatings only play a role of blocking and isolating between castings and moulds to achieve the purpose of anti-sticking sand. However, due to poor adhesion, low strength, poor fire resistance and large gas emission, common casting coatings are liable to cause defects such as sticking sand, sand holes, pore and carbon slag in castings.


advantage

1, It is convenient, quick, labor-saving, and has low fluid resistance. It can be operated frequently.

2, Simple structure, small size, short structure length, small size, light weight, suitable for large diameter valves.

3, Can transport mud, the least amount of liquid accumulated in the pipe mouth.

4, Under low pressure, can achieve a good seal.

5, The adjustment performance is good.
