Abstract
The utility model relates to a part of a sluice gate, in particular to a hexagonal flange surface bolt of a nuclear power sluice gate, which mainly solves the technical problem that in the prior art, the bolt is corroded and rusted and becomes loose on the sluice gate after the bolt is used for a time, therefore, the leakage happens, and safety accidents and the like are caused. The hexagonal flange surface bolt comprises a threaded rod (1) and is characterized in that one end of the threaded rod (1) is connected with a flange surface (2); a hexagonal bolt head (3) is fixed on the other surface of the flange surface; a cylindrical installing rod (4) is arranged between the flange surface (2) and the threaded rod (1); and the threaded rod, the installing rod, the flange surface and the hexagonal head are integrally formed.
Description
Technical field
The utility model relates to a kind of component of sluice gate, especially relates to a kind of nuclear power sluice gate hexagon flange bolt.
Background technique
Existing more product all need use screw in process of production; Particularly in the field of nuclear power sluice gate; Need screw be filled out that some fixes size and structure in the sluice gate,, then can cause more sluice gate to be revealed if fixed effect is bad; Waste great lot of water resources, even caused security incident.Chinese patent discloses a kind of polycylindser combination head tapping screw (notice of authorization number: CN201810640U); There is a self tapping flute its termination at screw thread; The head that it is characterized in that screw is combined by the identical part cylinder of Zhou Junbu along the garden of a plurality of radiuses; At this head part cylindrical section quantity identical a plurality of the screw grooves identical with a plurality of radiuses are arranged; This head a plurality of groove of screwing is combined by plane and plane with the center line oblique of this screw that a center line with screw coincides respectively; The angle on this two plane less than 90 degree greater than 60 degree, with the center line oblique plane of this screw oblique be that center from the polycylindser combination head tilts to export-oriented thread section direction.Chinese patent also discloses a kind of auto lock screw (notice of authorization number: CN201810632U); It is followed successively by from top to bottom and is provided with externally threaded screw head, screw rod and nut, it is characterized in that: screw rod is the hollow screw bar, and hollow screw bar both sides are respectively equipped with slotted hole; The width of slotted hole is less than the internal diameter of hollow screw bar; In the inner chamber of hollow screw bar spring is set, the spring upper end is provided with plug, and the both wings of plug stretch out outside the hollow screw bar through slotted hole; Spring is not less than the length of hollow screw bar under free extended configuration, the distance of the both wings of plug is greater than the diameter of nut.But these two kinds of screws are after using one section, and screw can become flexible on sluice gate, leak thereby produce, and then can cause security incident.
The model utility content
The utility model provides a kind of nuclear power sluice gate hexagon flange bolt; It mainly is to solve the existing in prior technology screw after using one section; Screw is can rust corrosion loosening on sluice gate, leaks thereby produce, and then can cause the technical problem of security incident etc.
The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals:
A kind of nuclear power sluice gate hexagon flange bolt of the utility model; Comprise threaded stem; One end of described threaded stem is connected with flanged surface; The another side of flanged surface is fixed with the hex head bolt head, is provided with columniform mounting rod between flanged surface and the threaded stem, and threaded stem, mounting rod, flanged surface, hex head bolt head are that integral body is processed.After threaded stem screws in and treats fixed component, can plain washer and spring washer be installed at the mounting rod place, not only can fix through screw thread like this, can also pass through spring washer, plain washer sealing, thereby make that the working life of whole bolt is longer.
As preferably, the outer end end face of described hex head bolt head is an arc surface, and the angle of cut of arc surface and hex head bolt head side is 15-30o.The hexagon nut body in use because the angle of cut of arc surface and hexagon nut body side is bigger, so the arc surface of its projection can withstand on the object to be assembled, hexagon flange bolt just can not come off so in use.
As preferably, pass through the arc surface transition between described mounting rod and the flanged surface large end face.When sluice gate uses, can prevent to rupture with mounting rod after flanged surface from receiving shearing force like this.
As preferably, described threaded stem, mounting rod, flanged surface, hex head bolt head are that stainless steel material is processed.Adopt the material of low carbon stainless steel to process, make that the manufacture cost of whole screw is lower.Corrosion resistance is better, and the material of low carbon stainless steel has more anti-grain boundary corrosion.
Therefore, the bolt of the utility model after use, can be at the mounting rod place mounting spring packing ring, plain washer; Make that the connection of bolt is more firm, and can play the effect of sealing, the working life of bolt is longer; Thereby can avoid causing security incident, simple and reasonable for structure.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the utility model;
Accompanying drawing 2 is a kind of side schematic views of Fig. 1.
Component, position and numbering among the figure: threaded stem 1, flanged surface 2, hex head bolt head 3, mounting rod 4, arc surface 5, spring washer 6, plain washer 7.
Embodiment
Pass through embodiment below, and combine accompanying drawing, do further bright specifically the technological scheme of the utility model.
Embodiment: a kind of nuclear power sluice gate hexagon flange bolt of this example; Like Fig. 1, Fig. 2; A threaded stem 1 is arranged, and an end of threaded stem is connected with flanged surface 2, and the another side of flanged surface is fixed with hex head bolt head 3; The outer end end face of hex head bolt head is an arc surface 5, and the angle of cut of arc surface and hex head bolt head side is 30o.Be provided with columniform mounting rod 4 between flanged surface 2 and the threaded stem 1, pass through the arc surface transition between mounting rod and flanged surface 2 large end faces.Threaded stem, mounting rod, flanged surface, hex head bolt head are that integral body is processed, and threaded stem, mounting rod, flanged surface, hex head bolt head are that stainless steel material is processed.
During use,, through threaded stem 1 whole bolt is screwed on the sluice gate then and gets final product at mounting rod 4 places cross-under upper spring packing ring 6, plain washer 7.
The above is merely the specific embodiment of the utility model; But the structure characteristic of the utility model is not limited thereto; Any those skilled in the art is in the field of the utility model, and variation of being done or modification all are encompassed among the claim of the utility model.
