Pay Attention, Here Are The Precautions For High-temperature Ball Valves!

The application range of 3 Piece Threaded Ball Valve is very wide. For example, it will be used in some fields such as chemical industry, metallurgy, hydropower, etc., but there are certain matters that need to be paid attention to during use. Let me introduce them to you below.

1. Because there are multiple layers of soft and hard stacked sealing rings fixed on the valve plate of the high-temperature ball valve, when the slide plate is in a normally open state, the medium will form a flushing force on the sealing surface of the high-temperature ball valve, and the soft sealing belt in the metal interlayer will directly affect the sealing after being flushed. Therefore, in the process of use, we must pay attention to the sealing performance.

2. When making a high-temperature ball valve, the diameter should be greater than dn 200. If the overall structure of the valve plate is too thick, there will be a great flow obstruction, that is, the diameter is limited by structural conditions.

3. In fact, the sealing performance between the sealing surface of the valve plate of the high-temperature ball valve and the valve seat mainly depends on the torque of the transmission device, so that the valve plate is pressed against the valve seat. If it is in a positive state, the higher the medium pressure, the tighter the sealing extrusion will be. Therefore, when the medium flows back, as the medium pressure continues to increase, when the unit positive pressure between the valve plate and the valve seat is smaller than the medium pressure, the seal of the high-temperature ball valve will begin to leak.

The above are the precautions for high-temperature ball valves. In daily use, you must pay more attention. In order to purchase higher quality and avoid wrong operation during use, the editor recommends that every consumer should understand the relevant high-temperature ball valve knowledge and know it well.
