Abstract
The utility model relates to a flange, in particular to a flange with a seal gasket. The flange with the seal groove comprises a flange body, wherein a through hole is formed in the center of the flange body; threaded holes are further formed at the edge of the flange body; an annular groove is formed in the flange body around the through hole; the depth of the annular groove is 1/3 of the height of the flange body; the flange is improved on the original basis; particularly, the sealability is improved to a certain extent; and as the annular groove is formed in the flange plate and internally provided with the seal gasket that is relatively wide, the seal gasket has low probability of corrosion, and the service life is greatly prolonged.
Description
Technical field
The utility model relates to a kind of flange, is specifically related to a kind of flange that has seal groove.
Background technique
Flange is a kind of pipe fitting joint commonly used, is mainly used in the connection of pipeline, along with country strengthens the dynamics of investment of Infrastructure and to the attention of environment; Various liquids and gases need be carried with pipeline, such as the transfering natural gas from the west to the east of investment type and waste water and gas discharging of environmental classes or the like, all need pipeline to carry; And the connection of pipeline all is a flange, and in recent years, country called energy-saving and emission-reduction; Just increasingly high to the technical requirements of all trades and professions, comprise requirement to flange.
At present, the flange plate that often uses is mainly used in some equipment such as valve; Generally all have 2-3 road groove on the flange plate, when two flanges connect, for fear of leaking or leaking gas; The capital is pressed into Graphite pad in this several roads groove, can play the effect of sealing and leakage proof to a certain extent, but Graphite pad is under the situation of corrosion for a long time; Obviously shorten working life, increased the frequency of maintenance.
Summary of the invention
The purpose of the utility model is to overcome deficiency of the prior art and a kind of less maintenance times is provided, and has strengthened the flange that has seal groove in working life.
The purpose of the utility model is achieved in that a kind of flange that has seal groove; Comprise flange body; Revenue centre position in flange body is provided with through hole; Edge in flange body also is provided with tapped hole, on flange body, is provided with circular groove around through hole, and the degree of depth of this circular groove is 1/3 of a flange body height.
Sealing gasket is installed in circular groove.
The thickness of described sealing gasket is 2-3 times of the circular groove degree of depth.
The utlity model has following advantage: the utility model is the improvement of on original basis, carrying out; Especially the problem of sealing has obtained certain improvement; Owing on flange plate, be provided with circular groove, in circular groove, be provided with sealing gasket, this sealing gasket is because than broad; So be not easy to be corroded, increased the life-span of using greatly.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
As shown in Figure 1; The utility model comprises flange body 1; Revenue centre position in flange body 1 is provided with through hole 2; Edge in flange body 1 also is provided with tapped hole 3, it is characterized in that: on flange body 1, be provided with circular groove around through hole 2, the degree of depth of this circular groove is 1/3 of flange body 1 height.
Sealing gasket 5 is installed in circular groove.
The thickness of described sealing gasket 5 is 2-3 times of the circular groove degree of depth.
The flange that the utility model relates to can make through the flange ring of waterline or fluting, and this production technology occurs at present, in the patent No. is 200810141239.5 patent, has mentioned this kind production method.
When flange docked, elder generation was encased inside sealing gasket in the circular groove on the flange, docked then, through bolt sealing gasket was compressed to get final product.
