A desuperheater spraying valve assembly includes an actuator coupled to a plug with a valve seat in the proximity of the plug. The plug is affixed to an actuator rod which transverses the body of the valve assembly. A spray tube may be affixed to the valve seat and at least one spray nozzle is affixed to the spray tube. The plug and the valve seat are conical in shape and when the plug is inserted into the valve, they form a seal.

Atomizing desuperheater shutoff apparatus and method

The present invention relates to an apparatus and method of deploying a desuperheater with a Seat-Ring designed to provide coolant injection at high temperature differential. The present invention's robust design provides for a high level of flexibility that allows operating at high temperature differentials between the coolant and the superheated fluid. The desuperheater Seat-Ring is made as a split hollow ring with a perpendicular slit traversing the ring's circumference. The opened slit design provides a high level of flexibility, which allows the seat ring to sustain severe temperature extremes by reducing thermal stress. The coolant is supplied to the seat ring through a specially designed coolant nipple liner connected to the seat-ring.

Desuperheater seat-ring apparatus

The present invention is directed to a desuperheater spraying valve assembly. More particularly, the invention provides a new and improved valve assembly, whereby cooling liquid may be controllably injected into a gas or a liquid stream, typically steam, to selectively maintain the gas or liquid at a predetermined temperature level. In a possible embodiment of the present invention, a class V valve assembly is disclosed. It comprises an actuator coupled to a plug with a valve seat in the proximity of said plug. The plug is affixed to an actuator rod which transverses the body of the valve assembly. A spray tube may be affixed to said valve seat and at least one spray nozzle is affixed to a to the spray tube. The plug and said valve seat are conical in shape as to when said plug is inserted into said valve, they form a seal.
