Abstract
The invention relates to a jacking device for a dryer of a pressurized water reactor steam generator. The jacking device comprises a middle connecting plate, side jacking plates located on the left side and the right side of the middle connecting plate and at least two sets of connecting rod assemblies used for connecting the middle connecting plate and the side jacking plates; each set of the connecting rod assemblies comprise a left connecting rod and a right connecting rod which are connected to the middle connecting plate, the left side jacking plate and the right side jacking plate. The jacking device has the advantages that the enough jacking force can be supplied to a corrugated plate; meanwhile, the structure is compact, and the window area of the dryer is greatly increased.
Description
Technical field
The present invention relates to the steam generator of presurized water reactor in nuclear power station, particularly relate to a kind of holding device of PWR steam generator drier.
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, makes the water of secondary side become moist steam.Moist steam, after initial separator, Gravity Separation district, drier, produces the dry saturated steam met design requirement, and dry saturated steam is used for driving steam turbine and generates electricity.
Drier is last one separator of steam generator.Moist steam is through drier core component--carry out curvilinear motion during corrugated sheet, under the effect of centrifugal force, inertia force and adhesive force, the water droplet in steam is attached on corrugated sheet, and forms moisture film.
And holding device is the important component part of drier, is mainly used in the corrugated sheet assembly compressing drier, makes the clearance requirement reaching design between corrugated sheet assembly.
Summary of the invention
The present invention is exactly to solve the problem, and overcomes the problem in prior art existing for drier, the invention provides a kind of PWR steam generator drier holding device to satisfy the demands.
To achieve these goals, technical scheme of the present invention is as follows:
A kind of PWR steam generator drier holding device, it is characterized in that, comprise middle connecting plate and the side top board being arranged at middle connecting plate both sides, described two pieces of side top boards are connected with middle connecting plate by least two group link assemblies, often organize link assembly and comprise connecting rod and bearing pin.
Above-mentioned a kind of PWR steam generator drier holding device, is characterized in that, described side plate is by link assembly and left and right sides top middle connecting plate pin joint.。
Above-mentioned a kind of PWR steam generator drier holding device, is characterized in that, by the upper and lower displacement of middle connecting plate, side plate is expanded outwardly or inwardly shrinks, and reaches corrugated sheet and holds out against or lax effect.
The invention has the beneficial effects as follows:
This holding device can provide enough pressures for corrugated sheet, and this holding device compact conformation, greatly increases the window area of drier simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Detailed description of the invention
The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the present invention further.
Referring to Fig. 1, a kind of PWR steam generator drier holding device, comprises middle connecting plate 100 and is arranged at two pieces of side top boards, 200, two pieces of side top boards 200 of middle connecting plate 100 both sides by least two group connecting rods 300 and middle top board 100 pin joints.When operation, the each separative element of drier of steam generator arranges a holding device, holding device makes the angle of connecting rod 310 change thus controls the position of the side top board 200 of both sides by regulating the upper-lower position of middle top board 100, for corrugated sheet provides effective thrust.
The top, one end of middle top board 100 is provided with jacking block 400, jacking block 400 is arranged at the top that two connecting rods 310 tilted form the middle connecting plate 100 on the opposite side direction of opening direction, in the process that reality uses, only need to promote jacking block 400 just can realize regulating the height of middle top board 100, thus regulate the position of side, both sides top board 200.
The invention has the beneficial effects as follows: this holding device can provide effective thrust for corrugated sheet, simultaneously the window area of drier that increases greatly of this holding device compact conformation.
More than show and describe general principle of the present invention, principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present invention; the present invention also has various changes and modifications without departing from the spirit and scope of the present invention, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
Claims (3)
