Abstract
The utility model relates to a pipeline connecting piece, in particular to an embedded bolt flange, solving the problems of complex operation, high consumption of time and labor, low construction efficiency, and the like when the existing two flanges are connected with each other by bolts and nuts. The embedded bolt flange comprises a pipeline connecting hole positioned at the center of a flange face and bolt installation holes uniformly distributed on the circumference of the flange face, wherein each bolt installation hole comprises a screw cap hole the shape of which is matched with a screwcap and a screw rod hole the shape of which is matched with a screw rod. In the utility mode, the embedded bolt flange is matched with the existing flange for use, a bolt penetrates through the boltinstallation holes of two flanges which are in well butt joint with each other, the screw cap thereof is exactly embedded and positioned in the screw cap hole of the embedded bolt flange, and a nut isscrewed on after the tail end of the screw rod penetrates through the existing flange. Operating personnel only need to tightly screw the nut at the tail end of the screw rod on one side of the existing flange, and therefore the embedded bolt flange has the advantages of time-saving and labor-saving operation, reduced labor intensity of workers, increased efficiency of construction, easy processing and low manufacturing cost.
Description
Technical field
The utility model relates to a kind of pipe joint, is specially a kind of embedded bolt flange dish.
Background technique
Flange plate is the important accessory that pipeline enclosure connects, the flange plate center has the pipeline attachment hole that is communicated with pipeline, the border is evenly equipped with bolt mounting holes, when using usually, earlier two flange plate are welded on respectively on the mouth of pipe of two pipelines that will connect, the through hole that wherein is positioned at the center communicates with pipeline, and the bolt mounting holes with two flange plate borders tightens together with bolt and nut then, thereby two pipelines are coupled together.In above-mentioned two flange plate connection procedures, outside often need tighting a bolt on the other hand, operator are exposed at the nut of a side flange panel surface, another hand to constantly screw be positioned at the opposite side flange plate and with the terminal supporting nut of bolt, successively all attachment holes on two flange plate are coupled together like this, complex operation, waste time and energy, efficiency of construction is lower, especially for large-scale pipelines such as natural gas tube, drain pipes, diameter more than 1.5-2m, just needs more people to cooperate and finishes the bolt and nut terminal operation usually this moment.
Summary of the invention
Problems such as when the utility model connects by bolt and nut in order to solve existing two flange plate, having complex operation, waste time and energy, efficiency of construction is low provides a kind of embedded bolt flange dish.
The utility model is to adopt following technological scheme to realize: embedded bolt flange dish, comprise pipeline attachment hole that is positioned at the card center and the bolt mounting holes that is distributed on the card border, innovative point of the present utility model is that bolt mounting holes constitutes by the screw cap hole that coincide mutually with the nut shape and with screw hole that the screw rod shape is coincide mutually.
Adopt structural design of the present utility model, on the basis of original screw hole, set up screw cap hole, common formation bolt mounting holes, when being used for the pipeline connection, the flange plate of structural type described in the utility model and the flange plate of existing structure form are used, like this, bolt is penetrated in the bolt mounting holes on two flange plate that connect, its nut is just in time embedded and be positioned in the screw cap hole of flange plate described in the utility model, the screw rod end screws on nut after passing existing flange plate, operator only need to get final product with the nut that spanner screws the screw rod end in existing flange plate one side, and it is time saving and energy saving to operate, and has reduced working strength of workers, improved efficiency of construction, and processing is simple, and fabricating cost is lower, has certain popularization value and use value.
Description of drawings
Fig. 1 is a structural representation of the present utility model
Fig. 2 is the A-A sectional view of Fig. 1
Among the figure: 1-card 2-pipeline attachment hole 3-screw cap hole 4-screw hole
Embodiment
Embedded bolt flange dish, as shown in Figure 1, comprise pipeline attachment hole 2 that is positioned at card 1 center and the bolt mounting holes that is distributed on card 1 border, as shown in Figure 2, bolt mounting holes constitutes by the screw cap hole 3 that coincide mutually with the nut shape and with screw hole 4 that the screw rod shape is coincide mutually, because the used bolt of flange plate is generally hexagon nut, so the screw cap hole shape of cross section is a Hexagon.
The flange plate of flange plate described in the utility model and existing structure form must use in pairs, and is the same with existing structure in addition, can increase seal ring between two flange plate.During concrete the use, just two flange plate are welded on respectively on the mouth of pipe of two pipelines that will connect earlier, the pipeline attachment hole that wherein is positioned at the center communicates with pipeline, bolt mounting holes is corresponding one by one, then bolt is inserted in the corresponding bolts mounting hole one by one, and make nut just in time embed and be positioned in the screw cap hole of flange plate described in the utility model, the screw rod end screws on nut after passing existing flange plate, and operator only need to get final product with the nut that spanner screws the screw rod end one by one in existing flange plate one side.
Claims (1)
1, a kind of embedded bolt flange dish, comprise pipeline attachment hole (2) that is positioned at card (1) center and the bolt mounting holes that is distributed on card (1) border, it is characterized in that bolt mounting holes constitutes by the screw cap hole (3) that coincide mutually with the nut shape and with screw hole (4) that the screw rod shape is coincide mutually.
