Abstract
A kind of expansion joint self-balancing type structure, comprise end face flange, rubber expansion joint, described rubber expansion joint is set to three, between rubber expansion joint and rubber expansion joint, be provided with spacer flanger, Limit screw links together two spacer flangers and an end face flange, is evenly equipped with three Limit screws on each end face flange.The utility model self can balance because using the collapsing force of the blind plate reaction thrust that expansion joint brings, improved working life and the Safety performance of pipeline, reduced maintenance load, reduced workman's labor intensity, reduced cost of production.
Description
Technical field
The utility model relates to nuclear electricity field, relates in particular to a kind of for the expansion joint self-balancing type structure on 1, No. 2 unit secondary circuit pipelines of nuclear power plant.
Background technique
On 1, No. 2 unit secondary circuit pipelines of nuclear power plant, conventionally select expansion joint as being flexible coupling, its effect is to play compensating action in heat distribution pipe network, in being connected of equipment and pipeline.This compensating action both can meet the pipe networks such as power or heating power due to the variation of temperature and pressure cause pipeline elongate or shorten, also can meet every displacement that the deviation due to mounting point causes.Because pipeline is used expansion joint, in pipeline, produced blind plate power, make pipeline be subject to the destruction of blind plate power, working life is short; Traditional expansion joint structure is unreasonable, not high pressure resistant, and rubber excessively extends and fatigue life of producing reduces, and the perishable expansion joint bulk life time that causes of external pressure-resistent ring declines, inapplicable high pressure occasion.
Summary of the invention
The purpose of this utility model is to provide a kind of expansion joint self-balancing type structure, expansion joint self can balance because using the collapsing force of the blind plate reaction thrust that expansion joint brings, the destruction that pipeline is not stressed, can improve working life and the Safety performance of pipeline, reduce maintenance load, the labor intensity that reduces workman, reduces production costs.
The utility model is achieved in that a kind of expansion joint self-balancing type structure, comprise end face flange, rubber expansion joint, it is characterized in that: described rubber expansion joint is set to three, between rubber expansion joint and rubber expansion joint, be provided with spacer flanger, Limit screw links together two spacer flangers and an end face flange, is evenly equipped with three Limit screws on each end face flange.
Rubber expansion joint described in the utility model is comprised of interior pressure-resistent ring, reinforcement steel wire, outer pressure-resistent ring, and several reinforcement steel wires are distributed between interior pressure-resistent ring and outer pressure-resistent ring.
Limit screw described in the utility model two ends are respectively arranged with two groups of spherical nut gasket assemblies; Limit screw has two kinds with the Placement of flange: mode one: Limit screw one end tightens together with end face flange by spherical nut gasket assembly, and the spacer flanger of the other end is spacing by one group of spherical nut gasket assembly; Mode two: Limit screw one end tightens together with spacer flanger by spherical nut gasket assembly, the end face flange of the other end is spacing by one group of spherical nut gasket assembly.
Two kinds of Placements of Limit screw described in the utility model and flange are crisscross arranged.
On spacer flanger described in the utility model, be evenly equipped with six Limit screws.
The utility model self can balance because using the collapsing force of the blind plate reaction thrust that expansion joint brings, improved working life and the Safety performance of pipeline, reduced maintenance load, reduced workman's labor intensity, reduced cost of production.
Accompanying drawing explanation
Fig. 1 is the plan view in the utility model structural representation;
In figure 1, straight pipe flange A, 2, stud, 3, spherical nut gasket assembly, 4, end face flange, 6, rubber expansion joint, 7, spacer flanger, 8, Limit screw, 9, straight pipe flange B, 10, interior pressure-resistent ring, 11, reinforcement steel wire, 12, outer pressure-resistent ring.
Embodiment:
Below in conjunction with accompanying drawing, the utility model is further illustrated:
With reference to accompanying drawing, a kind of expansion joint self-balancing type structure, comprise end face flange 1, rubber expansion joint 6, it is characterized in that: described rubber expansion joint 6 is set to three, between rubber expansion joint 6 and rubber expansion joint 6, be provided with spacer flanger 7, Limit screw 8 links together two spacer flangers 7 and an end face flange 1, is evenly equipped with three Limit screws 8 on each end face flange 1.Described rubber expansion joint 6 is comprised of interior pressure-resistent ring 10, reinforcement steel wire 11, outer pressure-resistent ring 12, and several reinforcement steel wires 11 are distributed between interior pressure-resistent ring 10 and outer pressure-resistent ring 12.Described Limit screw 8 two ends are respectively arranged with two groups of spherical nut gasket assemblies 3; Limit screw 8 has two kinds with the Placement of flange: mode one: Limit screw 8 one end tighten together with end face flange 1 by spherical nut gasket assembly 3, and the spacer flanger 7 of the other end is spacing by one group of spherical nut gasket assembly 3; Mode two: Limit screw 8 one end tighten together with spacer flanger 7 by spherical nut gasket assembly 3, the end face flange 1 of the other end is spacing by one group of spherical nut gasket assembly 3.Described Limit screw 8 is crisscross arranged with two kinds of Placements of flange.On described spacer flanger 7, be evenly equipped with six Limit screws 8.During concrete enforcement, rubber expansion joint of the present utility model is designed to: flange integral sealing face, the self-balancing type rubber expansion joint structure of the high arch of wrap style mountain type, is generally made into 3 wave modes, the rational Placement of Limit screw and increased interior pressure-resistent ring and reinforcement steel wire; Make the utlity model has following characteristics: 1, self can balance because using the collapsing force of the blind plate reaction thrust that expansion joint brings, solved and cannot carry out the fixing industry design challenges of support to pipeline; 2, ultrahigh pressure and anti-vacuum performance design, and have improved Safety performance and the Applicable scope of product; 3, interior pressure-resistent ring has solved the problem that outer pressure-resistent ring corrosion causes expansion joint bulk life time to decline; Solved without pressure-resistent ring product, rubber excessively extends and fatigue life of producing reduces, the problem that product bulk life time is declined; Solved vacuum performance and vacuum deformation rate, life of product is further improved; 4, adopt a plurality of expansion joints to obtain larger displacement capacity; 5, flange integral sealing face, without using pad, further improves the anticorrosion grade of flange during installation.
