Abstract
The utility model relates to a pipeline connecting member, and particularly to a flange plate. The flange plate comprises a plate body, wherein one side of the plate body is a sealing end while the other side per se is a pipeline connecting end; the sealing end protrudes outwards with respect to the plate body to form a sealed lug boss; at least two pipeline fixing grooves are formed in the pipeline connecting end. The flange plate is connected firmly, good in sealing effect and strong in universality.
Description
Technical field
The utility model relates to a kind of pipe joint, particularly a kind of flange plate.
Background technique
Flange plate is widely used in mechanical field as link.General flange plate requirement of strength is higher, its sealing surface is all circular planes shape, two flange plate symmetries are installed together, the contact of the sealing surface of two flange plate is as stuffing box packing by seal washer, there are error or dislocation while installing due to symmetry, and the seal washer dislocation is lost, or destroyed by rush of water by barotropic fluid due to seal washer self aging cracking, cause sealing effect bad, thereby cause the leakage of material.And when two pipe diameters that connect are different, need to use the flange plate docking of different model, more easily cause error, sealability can't guarantee.
Summary of the invention
For solving the deficiencies in the prior art, the purpose of this utility model is to provide a kind of and is connected firmly, the flange plate of good sealing effect, highly versatile.
In order to realize above-mentioned target, the utility model adopts following technological scheme:
A kind of flange plate, comprise disk body, and described disk body one side is sealed end, and opposite side is the pipeline connecting end; The relative disk body outwardly convex of described sealed end forms seal boss; Described pipeline connecting end has at least two pipeline fixed grooves.
The external diameter edge of described disk body is provided with 8 positioning spiro pits, and the internal diameter edge of described disk body is provided with 4 positioning spiro pits.
Described seal boss is provided with 8 retaining thread holes.
Described pipeline fixed groove inboard is provided with sealing layer.
Usefulness of the present utility model is: flangeseal performance of the present utility model is good, long service life, and versatility is good.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the A-A sectional view of Fig. 1.
The implication of reference character in figure: 1 flange plate; 2 disk bodies; 3 sealed ends; 4 pipeline connecting ends; 5 seal bosses; 6 pipeline fixed grooves; 7 retaining thread holes; 8 positioning spiro pits; 9 positioning spiro pits.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is done to concrete introduction.
A kind of flange plate 1 as shown in Figure 1-2, comprise disk body 2, and disk body one side is sealed end 3, and opposite side is pipeline connecting end 4.The relative disk body outwardly convex of sealed end 3 forms seal boss 5.Seal boss 5 is provided with 8 retaining thread holes 7.When two flange plate are used in conjunction with, the protrusion surface of seal boss 5 is sealing surface, between two sealing surfaces, seal washer is arranged, and by retaining thread hole 7, is fixedly connected with two flange plate.Due to seal boss protrude from the flange disk body, whether the connection that can observe two flange plate in installation process exists error, visual installation reduces alignment error.Pipeline connecting end 4 has at least two pipeline fixed grooves 6, and the inboard of pipeline fixed groove 6 is provided with sealing layer.The pipeline of different tube diameters can be fixed in different pipeline fixed grooves, the diameter of pipeline fixed groove increases from inside to outside successively, therefore, when if two pipe diameters that connected by flange plate are not identical, still can connect with identical flange plate, improve suitability, reduce alignment error, improve sealing.The external diameter edge of disk body 2 is provided with 8 positioning spiro pits 8, and internal diameter edge is provided with 4 positioning spiro pits 9.The even interval of positioning spiro pit 8 and positioning spiro pit 9 substep is on the disk body circumference.The distribution of positioning spiro pit has increased the position stability of seal boss, further improves sealability.
Above demonstration and described basic principle of the present utility model, major character and advantage.The technician of the industry should understand, and above-described embodiment does not limit the utility model in any form, and all employings are equal to replaces or technological scheme that the mode of equivalent transformation obtains, all drops in protection domain of the present utility model.
Claims (4)
1. a flange plate, comprise disk body, it is characterized in that, described disk body one side is sealed end, and opposite side is the pipeline connecting end; The relative disk body outwardly convex of described sealed end forms seal boss; Described pipeline connecting end has at least two pipeline fixed grooves.
