Abstract
The invention provides a support spacer block for a double hook waveform plate of a pressurized water reactor steam generator dryer, and can meet the design requirements of the steam generator dryers. A support spacer block is used for separation of every two waveform plates of the dryer; the support spacer block has a corrugated curved shape matching that of the waveform plate; the peak of the corrugated curve of the support spacer block is provided with a groove; the top of the support spacer block is provided with a top end extending outwardly; and the left and right sides of the bottom of the support spacer block are provided with one stand bar extending outwardly respectively. The support spacer block for the double hook waveform plate of the pressurized water reactor steam generator dryer has small size and good support and hydrophobic properties to ensure that the spacing between the waveform plates achieves the desired value, so that the degree of compression of the waveform plates meets the requirements, and little influence is exerted on flow field inside the dryer. The groove arranged on the middle can help water drainage, so as to satisfy the design requirement of the steam generator dryer.
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.
