Why do we need pressure regulators - bypass valves and pressure reducing valves to regulate the pressure after ourselves?
At the enterprise, there are a lot of consumers of heat energy, some need a pressure of 2 bar, others 4, and a third 8, but you always have to produce steam with maximum parameters, and only then reduce the pressure to the required value. Pressure regulators are not only pressure reducing valves, but also bypass valves, however, bypass valves are not so often used in steam and condensate systems.
The pressure reducing valve is
pressure regulator After myself, the main purpose is to reduce the pressure after itself and maintain it at a certain level (in the area after itself), regardless of pressure surges to the regulator (at its inlet). Pressure surges are caused by changes in steam consumption, the pressure regulator maintains a constant pressure level.The bypass valve is pressure regulator TO itself, is used much less frequently than a pressure reducing valve, it is practically not used for steam. Bypass valves are most commonly used to bypass pumps. When the pump delivers too much pressure, the bypass valve leads this excess pressure back to the suction (bypass pressure), such a system saves the pump.
3 main types of pressure reducing valves for steam
from simpler to more complexbellows type(e.g. ADCA PRV25)
It has a flexible metal bellows inside with a relatively small area, resulting in the bellows pressure reducing valve being considered the least sensitive, suitable for coarser downstream pressure adjustment. If the flow rate of steam passing through the valve does not change significantly during operation, a bellows-type pressure reducing valve will do just fine. Due to low accuracy and sensitivity, this valve is produced only in small sizes DN 15-20-25. One of the disadvantages of this valve is the relatively small throughput. The main advantage is the simple design.Pressure regulator downstream membrane(e.g. ADCA RP45)
There is a rubber membrane inside the metal plate, the membrane area is much higher than on the bellows pressure reducing valve, hence the higher sensitivity and relatively greater accuracy of maintaining pressure after itself. A very common type of pressure reducing valves, capable of operating in systems with high dynamics of steam flow changes, in comparison with a bellows valve, a diaphragm valve has a higher throughput - this is also a significant plus. An extremely durable type of pressure reducing valve, if the filter in front of the pressure reducing valve is correctly installed - even the rubber membrane in it can work for more than 10 years.Pressure regulator downstream pilot(e.g. ADCA PRV47)
The main trump card of the pilot pressure regulator after itself is the highest sensitivity and adjustment accuracy.The most advanced design, the most accurate pressure regulator, but at the same time the most “gentle”. This valve is equipped with a piston drive, there are many small grooves in the design, as a result, the valve is very sensitive to steam quality. Under no circumstances should this pressure reducing valve be installed in a system with high level mechanical impurities in steam, it is recommended to use it with pipelines made of of stainless steel or install a filter fine cleaning pair (fabric), the only way to ensure long work such a valve
Selection of pressure regulator
Always install a pressure regulator downstream of a smaller size than the main pipeline! A common misconception is fitting a size-to-size pressure reducing valve.A pressure reducing valve that matches the pipe size always turns out to be more powerful than the technological process requires, because of this the valve does not work accurately, imagine a valve operating at 10-30% of its normal capacity, in fact it is not much different from the open-closed regulation ”and the main functionality of such a valve remains unused.
The main parameters for selecting a pressure regulator after yourself:
- Environment type.
- Inlet pressure.
- outlet pressure.
- Medium consumption (min. max).
- Medium temperature.
- Connection type.
THE VALVE DIAMETER WILL BE DETERMINED BASED ON STEAM, PRESSURE, FLOW AND MEDIUM AND NOT FROM THE PIPE DIAMETER.
Selection by pipe - absolutely not. When selecting a pressure reducing valve, it is always necessary to narrow the pipe in front of the valve and widen the pipeline BEHIND the valve.
What does the ideal steam system reducer look like?
The normal selection of the reduction node is carried out based on the parameters of the system.In a nutshell, we describe the principle of selecting a pressure reducing valve assembly.
Suppose the main pipeline before the pressure reducing valve is f 40, in this case the pressure reducing valve itself will turn out to be slightly smaller, approximately DN 32.
BEHIND the valve, it is usually necessary to expand the pipeline, usually drastically.
That is, BEFORE the pressure reducing valve diameter steam pipe was f 40, and BEHIND the pressure reducing valve, the pipe will need to be expanded to f 50 or even f 65. (rough)
Why is it necessary to expand the pipeline BEHIND the pressure reducing valve?
We lowered the pressure - the steam expanded - it is necessary to expand the pipeline to ensure the normal passage of steam through the system.
Tell us the details of your steam system and we will make a full calculation of the required pressure with optimal performance.
