How the pressure regulator works
The regulator automatically controls the output pressure to remain constant at a certain set pressure.
The pressure regulator is normally open and gradually closes as the output pressure increases.
The correct direction of steam flow from inside the pressure regulator is indicated by an arrow on its body.
The position of the plug and the free space between the plug and the seat controls the amount of steam output.
The controlled output pressure is transferred to the diaphragm through the condensation source and the control line and is placed in the reverse force position.
This force is used like the force applied by the springs to adjust the position of the plug, but in the reverse direction.
The amount of force applied by the springs can be changed by the adjustment nut.
This pressure relief valve is equipped with a stainless steel accordion piece by which the inlet pressure is balanced.
The input pressure is applied on the external surface of the accordion piece and thus the forces applied on the plug surface are neutralized by this reverse force.
What is a regulator?
The regulator is a device that, due to the internal mechanical systems, is able to take the high pressure of the incoming gas and deliver it with a lower pressure according to the consumer’s needs.
Therefore, the regulators have different sizes and different pressures.
Due to the mechanism it has, the regulator should be used in open environments.
For closed environments, a special type of secondary regulator called a balancer is used.
The balancer regulator does not have an upper shut-off system, a lower shut-off system, or a vent.
The vent is a mode in the regulator that may not work due to a sudden increase in gas pressure in the network of the high disconnection system of the regulator for any reason.
It is in this state that the regulator releases this gas as a vent in the air to prevent high pressure gas from entering the building.
