Abstract
The utility model provides a two-stage seal flange employing clamping sleeve connection and being used for pipelines, belongs to railway vehicle accessories, and is mainly suitable for connection and seal of brake pipes of vehicles. The two-stage seal flange comprises a connector body and a flange body and is characterized in that the flange body is connected with the connector body through a clamping sleeve; the connector body is sealed with the flange body through seal rings; and an E-shaped seal ring and a diamond-shaped seal ring are disposed between the connector body and the flange body and used for two-stage seal of the flange. The seal rings in the flange comprise the E-shaped seal ring and the diamond-shaped seal ring, which form two-stage stacked seal in the flange, realize reliable seal, are complementary in the seal function, perform combined protection on the flange, and thus protect the flange from rain, snow, sand blown by the wind, and corrosive medium through the two-stage protection.
Description
Technical field:
A kind of pipeline two-stage sealing flange that adopts cutting ferrule to connect belongs to railway vehicle fittings, mainly is applicable to connection and the sealing of brake pipe.
Background technique:
For a long time, brake tube for railway vehicle is single with flange arrangement, and sealing is poor, and unshielded measure, and the rigidity of flange is relatively poor, be out of shape greatlyr, easily causes the Brake pipe poor sealing, and pressure air is sewed, even inefficacy, affects the normal use of railway vehicle.
In recent years, the present situation that the brake tube for railway vehicle flange seal is bad, pressure air is sewed is not taken on a new look, and the trend that grows in intensity is arranged also, especially railway vehicle runs into abominable operation environment, such as low temperature, sleet, dust storm and aggressive medium etc., easily cause the joint and seal of Brake pipe flange to lose efficacy, seriously have influence on the traffic safety of railway vehicle.
Summary of the invention:
The utility model provides a kind of fittings body and flange body to adopt cutting ferrule to be connected, can to carry out two-stage sealing, the reliable pipeline flange of sealing for the problems referred to above.Its technological scheme is as follows:
It comprises fittings body and flange body, and its key technology is that flange body adopts cutting ferrule to be connected with fittings body, and fittings body and flange body seal by seal ring, E shape seal ring and rhombus seal ring are set between fittings body and flange body flange is implemented the two-stage sealing.
Compared with prior art, the beneficial effect that the utlity model has is:
Seal ring in the flange comprises E shape seal ring and rhombus seal ring, is in flange in the same plane, and E shape seal ring forms protection at internal layer to flange, and the rhombus seal ring forms protection in the periphery to flange.Two kinds of seal rings carry out the stacked sealing of two-stage in flange, sealing is reliable, and are complementary on sealing function, and flange is implemented the associating protection, and the two-stage protection can prevent effectively that sleet, dust storm and aggressive medium are to the damage of flange.
Description of drawings:
Fig. 1 is the utility model structural representation;
Fig. 2 is Fig. 1 plan view;
Fig. 3 is Fig. 1 partial enlarged drawing;
Fig. 4 is the utility model rhombus seal ring cross sectional representation.
Embodiment:
Such as Fig. 1-shown in Figure 4, the utility model comprises fittings body 4 and flange body 2, its key technology is that flange body 2 adopts cutting ferrule 1 to be connected with fittings body 4, fittings body 4 and flange body 2 arrange 3.2 pairs of flanges of E shape seal ring 3.1 and rhombus seal ring and implement the two-stage sealing by seal ring 3 sealings between fittings body 4 and flange body 2.E shape seal ring 3.1 and rhombus seal ring 3.2 are in flange in the same plane, and E shape seal ring 3.1 places flange inboard, and rhombus seal ring 3.2 places the flange outside.The shape of cross section of rhombus seal ring 3.2 is rhombus, the pair of horns of lozenge shape cross-section axial direction consists of axial seal section 5, the pair of horns of radial direction consists of radial seal section 6, and axial seal section 5 and radial seal section 6 are respectively circular arc, makes the seal ring cross section form rhombus.The axial height L of E shape seal ring 3.1 is 6-8mm, and the axial height L of rhombus seal ring 3.2 is 6-8mm, preferably 7mm.
