Abstract
The utility model relates to the technical field of a main pipeline pressure stabilizer of a pressurized water reactor nuclear power plant, and in particular discloses a spray filler neck for a main pipeline pressure stabilizer. The spray filler neck disclosed by the utility model comprises a main pipeline and a spray adapter tube integrally formed on the wall of the main pipeline, and a spoon-shaped element is fixed on one side of the spray adapter tube, wherein the spoon-shaped element is composed of a lower end extension segment of the inner wall of one side of the spray adapter tube and a semicircular segment in circular arc transition with the extension segment, simultaneously the spoon-shaped element faces to the flowing direction of a fluid in the main pipeline and takes up a 180-degree radian range in the axis direction of the spray adapter tube. The spray filler neck for the main pipeline pressure stabilizer in the utility model can be used for connecting a pressure stabilizer with a main system, and the spoon-shaped element in the spray filler neck can provide certain power for a reactor coolant medium in the main pipeline to enter the pressure stabilizer.
Description
Technical field
The utility model belongs to PWR nuclear power plant trunk line voltage stabilizer technical field, is specifically related to a kind of trunk line voltage stabilizer spraying pressure inlet.
Background technology
It is nuclear power plant voltage stabilizer and main system connecting tubes that trunk line voltage stabilizer injection spray pipe is taken over.Voltage stabilizer is one of PWR nuclear power plant major equipment; its function is: reactor is under startup, shutdown, steady state power operation, normal power variation and various accident conditions; it can rise the pressure of reactor coolant loop and control and protective effect, also has simultaneously assist to open heap, shutdown and remove airway dysfunction.When one circuit pressure rose, the method for keeping the voltage stabilizer constant pressure was the mist cooling step-down, made the interior subcooled water atomizing of trunk line spray into voltage stabilizer, suppressed pressure and raise.
Summary of the invention
The purpose of this utility model is to provide a kind of trunk line voltage stabilizer spraying pressure inlet, can connect voltage stabilizer and main system, and a determined power can be provided.
The technical solution of the utility model is as follows: a kind of trunk line voltage stabilizer spraying pressure inlet, this spraying pressure inlet comprise trunk line and on the trunk line tube wall integrally formed spraying take over, and spraying is taken over lower end one side and is fixed with a spoonful type spare, wherein, spoon type spare is taken over a side inwall lower end extension by spraying and is consisted of with the semicircle segmental arc of this extension arc transition.
Described spoon type spare be direction of flow in the trunk line, and occupies the radian scope of 180 ° on spraying adapter axis direction.
The length L of the extension in described spoon type spare is 40.6mm.
The radius-of-curvature of the semicircle segmental arc in described spoon type spare is 89.4mm.
Described trunk line is for being used for connecting the cylindrical drum tubular structure of voltage stabilizer and main system.
Described spraying nozzle inner wall is cylindrical structure.
The wall thickness D of described spoon type spare is 13.5mm, and length H is 76.2mm, surface roughness Ra≤6.3 μ m.
Remarkable result of the present utility model is: a kind of trunk line voltage stabilizer spraying pressure inlet described in the utility model, can be used for connecting voltage stabilizer and main system, and the spoon type spare in this spraying pressure inlet can provide certain power for trunk line reactor coolant medium enters voltage stabilizer.
