What is a crown valve?

Crown valve - also referred to as a stop valve - is an essential part of the steam boiler industrial system that is used for control and slowly distracts the pressure steam in the boiler. It can also be used to make the steam escape the boiler and enter the pipe system, provide heat, energy or other steam functions. These boiler systems are usually too large to be used anywhere, but in an industrial plant. The crown valve acquires its name from the site, which is given on the boiler - directly at the top or from the crown of the boiler unit.

Crown valves are also used as safety measures for boiler systems because they have regulatory organs that allow excessive pressure leakage that can accumulate if too long time can accumulate between the open and closed valve. The crown valve has indicators that allow the boiler operator to immediately determine whether the valve is open or not. Regulatory bodies also ensure that the boiler condition of the operaCeion is visible from any convenient point. These types of valves are not considered to be continuous release valves or controlled release valves, as the crown valves should either be open or firmly closed.

The earliest crown valves were usually made of cast iron, so they were very heavy and often unreliable. The cast iron would be tied under severe pressure, making it difficult to open the valve when the pressure is built behind it. After steel valves and bronze crowns became standard for setting, where the boiler units caused higher pressure on steel and alloy crown valves, it has rapidly become the standard among many methods of industrial crown valves.

6tels. If you do not do so, it can cause something called water hammering that occurs when the steam pressure is released too quickly and "hits" intersections in the pipe system. If ko isTLE closed by the crown valve too fast, there may be a sudden increase in the pressure of the boiler, which can damage the valves in the boiler system. Most often, the secondary valve is mounted in many high -pressure systems to prevent one of these circumstances.
