Full Capacity Welded Safety Valve For High Pressure / High Temperature Use

Full Capacity Welded Safety Valve For High Pressure And High Temperature Use

Product introduction:

Full capacity safety valve is used on steam medium equipment and pipelines in large thermal power plants as an overpressure protection device. This valve has the characteristics of high discharge coefficient, accurate opening pressure, small opening and closing pressure difference, good sealing, and easy adjustment. The full capacity spring safety valve is one of the leading products developed by our company. It can be used on the drum, superheater header, reheater, and pressure vessel of 220t/h to 410t/h boilers matched with 50000 KW and 100000 KW units, to prevent pressure increase beyond the allowable value and ensure safe operation of the unit. It has been widely used by users so far.

Product features:

1. Nozzle-shaped valve seat: Designed using the Lafarre nozzle principle, the steam flow rate at the outlet of the valve seat is supersonic, resulting in a large emission coefficient. The sealing surface of the valve seat is plasma sprayed with cobalt based hard alloy, which is wear-resistant, corrosion-resistant, and has a long service life.
2. The valve disc adopts a thermal stress compensation structure, which is divided into two parts: the valve disc and the hot valve disc. The purpose is to fully utilize the thermal deformation of the valve disc to achieve sealing. The hot valve disc is made into a tongue shaped structure to use its small elastic effect to prevent leakage.
3. Spring: The spring is a key component that determines the performance of a safety valve. Different springs are designed for different set pressures and opening and closing pressure differentials.
4. The valve stem head and the valve disc gasket are welded with cobalt based hard alloy, which has high hardness, wear resistance, and long service life.
