Abstract
The utility model provides a compact flange, which comprises a first flange body and a second flange body, and the first flange body is fastened with the second flange body in a butting manner. The compact flange is characterized in that: studs are evenly inserted in the outer circle parts of the first flange body and the second flange body, both ends of each stud are respectively provided with a nut, the tops of the first flange body and the second flange body are connected in a wedging manner, the roots of the first flange body and the second flange body are tightly jointed to realize axial sealing, and a seal ring is utilized to radially seal the first flange body and the second flange body. The utility model has the following advantages that: the space is saved, the weight is reduced by about 50 to 70 percent, material is saved, and meanwhile, the flange has an excellent sealing performance, and therefore realizing zero leakage.
Description
Technical field
The utility model relates to a kind of flange, relates in particular to a kind of compact type flange.
Background technique
What in decades, China quoted always is the ANSI flange and the European system flange of USS United States Standard.As time goes on, the defective of ANSI flange constantly comes out.
The sealing principle of ANSI flange is extremely simple: bolted two flange facing mutual extrusion flange gaskets also form sealing.But this also causes simultaneously the destruction that seals.In order to keep sealing, must keep huge bolt active force.For this reason, bolt will do more.And bigger bolt will mate bigger nut, and this just means that needing the bigger bolt of diameter is that last jack panel creates conditions.Hardly realize that the diameter of bolt is big more, the flange that is suitable for will limpen, and only way is exactly the wall thickness that increases flange part.Whole device will need great size and weight.
In addition, the main design shortcoming of ANSI flange is that it can not guarantee not have leakage fully.Deficiency in its design that Here it is: connection is dynamic, and all can cause moving between the flanged surface such as thermal expansion and yo-yo cyclic loading, influences the function of flange, thereby makes the integrity of flange impaired, finally causes leaking.
Summary of the invention
The purpose of this utility model provides the flange that a kind of size is little and sealability is good.
In order to achieve the above object, the technical solution of the utility model has provided a kind of compact type flange, the first flange matrix and the second flange matrix that comprise make-up, it is characterized in that, evenly on the excircle part of the first flange matrix and the second flange matrix must be equipped with stud bolt, two ends at stud bolt are respectively equipped with nut, wedge shape is connected between the top of the first flange matrix and the second flange matrix, fit tightly realization axial seal between the root of the first flange matrix and the second flange matrix, pass through the seal ring radial seal between the first flange matrix and the second flange matrix.
Further, be oval arc transition between the bottom of the described first flange matrix and the second flange matrix and the excircle part.
The utility model has the advantages that: not only save the space, to have alleviated weight about 50%～70%, saved material, have excellent sealing ability simultaneously and guarantee that flange realizes zero leakage.

Fig. 2 is a schematic representation after the assembling of a kind of compact type flange of the present utility model.
Embodiment
Specify the utility model below in conjunction with embodiment.
Embodiment
As shown in Figures 1 and 2, a kind of compact type flange that provides for the utility model, the first flange matrix 1 and the second flange matrix 2 that comprise make-up, evenly on the excircle part of the first flange matrix 1 and the second flange matrix 2 must be equipped with stud bolt 3, be respectively equipped with nut 4 at the two ends of stud bolt 3, wedge shape is connected between the top of the first flange matrix 1 and the second flange matrix 2, fit tightly realization axial seal between the root of the first flange matrix 1 and the second flange matrix 2, pass through seal ring 5 radial seals between the first flange matrix 1 and the second flange matrix 2.Between the bottom of the described first flange matrix 1 and the second flange matrix 2 and the excircle part is oval arc transition.
The bottom of the first flange matrix 1 of the present utility model and the second flange matrix 2 and the oval arc transition between the excircle part can reduce stress and concentrate.Adopt stud bolt 3 can ignore dynamic stress, simultaneously, also need not to lubricate.The top of the first flange matrix 1 and the second flange matrix 2 can not make flange bear excessive stress when adopting wedge shape to be connected assembling, can also hinder entering of foreign matter.Owing to be returned to the trend of former inclined-plane state because of pressurized has at the first flange matrix 1 and the second flange matrix 2, therefore seal ring 5 can seal voluntarily, and seal ring 5 need not to lubricate, and can not wear and tear, installed load can not damage seal ring 5, and seal ring 5 is reusable simultaneously.
Claims (2)
1. compact type flange, the first flange matrix (1) and the second flange matrix (2) that comprise make-up, it is characterized in that, evenly on the excircle part of the first flange matrix (1) and the second flange matrix (2) must be equipped with stud bolt (3), be respectively equipped with nut (4) at the two ends of stud bolt (3), wedge shape is connected between the top of the first flange matrix (1) and the second flange matrix (2), fit tightly realization axial seal between the root of the first flange matrix (1) and the second flange matrix (2), pass through seal ring (5) radial seal between the first flange matrix (1) and the second flange matrix (2).
2. a kind of compact type flange as claimed in claim 1 is characterized in that, is oval arc transition between the bottom of the described first flange matrix (1) and the second flange matrix (2) and the excircle part.
