The principle of steam pressure reducing valve decompression in steam system
Why should the pressure need to be reduced in the steam system?
When the boiler is operated at a set pressure, reducing pressure can avoid generating wet steam at low pressure.
In the case of high pressure, it is easy to transport the medium.
The pressure of various equipment in the pipeline is different.
Decompression can save energy, because the latent heat of decompression is large and there is little flash evaporation.
The pressure reducing valve can control the medium temperature.
It can stabilize the pressure of the downstream steam system and improve the quality of the steam to obtain dry steam.
The role of steam pressure reducing valve:
Under certain circumstances, the steam pressure reducing valve can protect the equipment behind it, it's just like that the Y-type filter is to protect the equipment behind. However, the pressure reducing valve adopts the valve body of the regulating valve to control the opening of the flow, and at the same time adjusts the opening of the valve disc by the effect of the downstream pressure to keep the downstream pressure within a certain range to maintain the pressure of the entire steam system balance.
