Abstract
The utility model provides a can satisfy the PWR steam generator desicator is with supporting spacer block of steam generator desicator designing requirement. The desicator in use supporting spacer block looks interval between per two wave plates, wherein: the supporting spacer block be the crooked shape of ripple, the crooked shape of ripple that should support the spacer block is mated with the crooked shape of wave plate, the crest department that the ripple is crooked at the supporting spacer block is provided with the recess, top at the supporting spacer block has 1 top of outwards extending, respectively have 1 stabilizer blade that outwards extends about the bottom of supporting spacer block. PWR steam generator desicator is with supporting spacer block, its is small, supporting and hydrophobicity can be good, guarantees that clearance between the wave plate reaches to want the evaluation, makes the tight degree in wave plate top reach the requirement, and is little to the influence of the flow field in the desicator. The middle recess that sets up can help hydrophobicly, can satisfy the designing requirement of steam generator desicator.
Description
Technical field
The present invention relates to PWR steam generator drier design field, be specifically related to a kind of PWR steam generator drier supporting spacer block.
Background technology
Steam generator is the heat transmission equipment between PWR nuclear power plant one, secondary circuit, for the heat of reactor coolant is passed to secondary side, make the water of secondary side become steam, steam, after initial separator and drier, leaves steam generator rear drive steam turbine and generates electricity.
Supporting spacer block is the important component part of dryer for steam generator, and it can make the corrugated sheet in drier mutually compress location, makes plate spacing meet the requirements of value, therefore makes separating effect reach designing requirement.
In steam generator, the supporting spacer block structural design of drier is unreasonable will affect the performance of drier, and steam-water separation effect is fallen flat, or make plate compress not and Flow vibration or vibrations occur.
Summary of the invention
The object of the present invention is to provide a kind of volume little, supporting and hydrophobic performance good, can meet dryer for steam generator designing requirement PWR steam generator drier double hook corrugated sheet support spacer block.
Realize the technical scheme of the object of the invention:
A kind of PWR steam generator drier double hook corrugated sheet supporting spacer block, supporting spacer block is used between every two pieces of corrugated sheets separately in described drier, wherein: described supporting spacer block is ripple curved shape, the ripple curved shape of this supporting spacer block mates with the curved shape of corrugated sheet;
The crest place bending at the ripple of supporting spacer block is provided with groove;
In the top that the top of supporting spacer block extends outward with 1.The leg respectively extended outward with 1 about the bottom of supporting spacer block.
A kind of PWR steam generator drier double hook corrugated sheet supporting spacer block as above, the groove shapes described in it is ripple bending, and the both sides of the edge of groove are right-angle structure.
A kind of PWR steam generator drier supporting spacer block as above, the hook extended outward described in it is that 40 ~ 70 ° of angles are arranged with supporting spacer block body.
Effect of the present invention is:
PWR steam generator drier supporting spacer block of the present invention, its volume is little, supporting and hydrophobic performance good, dryer for steam generator designing requirement can be met: namely ensure that corrugated sheet spacing reaches required value, and corrugated sheet is held out against, little to the flow in drier.
The Area of bearing of supporting spacer block of the present invention is large, and stability is good, and the middle groove arranged can help hydrophobic, can meet the designing requirement of dryer for steam generator.
Accompanying drawing explanation
Fig. 1 is a kind of PWR steam generator drier supporting spacer block structural representation of the present invention.
In figure: 1 is groove, 2 is top, and (3) and (4) are leg.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, a kind of PWR steam generator drier supporting spacer block of the present invention is further described.
In PWR steam generator drier of the present invention, use supporting spacer block between every two pieces of corrugated sheets separately.
As shown in Figure 1, supporting spacer block of the present invention is ripple curved shape, and the ripple curved shape of this supporting spacer block mates with the curved shape of corrugated sheet;
The crest place bending at the ripple of supporting spacer block is provided with groove 1.This groove 1 shape is ripple bending, and the both sides of the edge of groove 1 are right-angle structure.
The crest place bending at the ripple of supporting spacer block is provided with groove (1); At the top of supporting spacer block with 1 top extended outward (2), top 2 is that 40 ~ 70 ° of angles are arranged with supporting spacer block body, and its effect is to withstand adjacent corrugated sheet;
Each with 1 leg extended outward (3) and (4) about the bottom of supporting spacer block, it act as in the gap of the hydrophobic hook being inserted in corrugated sheet to be formed and supports.
Supporting spacer block of the present invention is in use:
In drier, use supporting spacer block of the present invention separately between every two pieces of corrugated sheets, corrugated sheet spacing is met design requirement, and corrugated sheet is compressed mutually.
Greatly, good stability, the middle groove arranged can help hydrophobic for the two sides of supporting spacer block of the present invention and corrugated sheet Area of bearing.
Above embodiments of the invention are explained in detail, above-mentioned embodiment is only optimum embodiment of the present invention, but the present invention is not limited to above-described embodiment, in the ken that those of ordinary skill in the art possess, various change can also be made under the prerequisite not departing from present inventive concept.
Claims (3)
1. a PWR steam generator drier supporting spacer block, uses supporting spacer block separately in described drier, it is characterized in that between every two pieces of corrugated sheets:
