11. ESSURE E ATMOSPHERIC PRESSURE Figure 3 Type Y692 with External Registration Operational Schematic When the liquid level drops and vessel pressure decreases below the setting of the control spring the spring force on the diaphragm opens the disk assembly to supply the required flow of gas to the vessel When vessel pressure has been satisfied control pressure tends to increase slightly acting on the diaphragm When the control vessel pressure exceeds the control spring setting the diaphragm moves to close the disk assembly The Type Y692 Gas Blanketing Regulator provides a constant set pressure for accurate gas blanketing When vessel pressure decreases below the control spring setpoint the force of the spring moves the disk away from the orifice allowing gas to flow into the vessel As the vessel pressure increases the increase is sensed by the diaphragm through the pitot tube or control line This movement of the diaphragm causes the disk to move toward the orifice decreasing the flow of blanketing gas When the vessel pressure reaches the system setpoint the disk will seat against the orifice shutting off the flow of gas Y692 Installation Personal injury equipment damage or leakage due to escaping accumulated gas or bursting of pressure containing parts may result if the gas blanketing regulator is overpressured or installed where service conditions could exceed the limits given in Specifications section
