Abstract

The utility model provides a triangular flange used for a pipeline, belongs to railway vehicle accessories, and particularly relates to a connecting and sealing piece used for a vehicle brake pipe. The triangular flange used for the pipeline comprises a flange body and a joint body, the flange body is connected with the joint body through a clamping sleeve, and a seal ring is padded between the clamping sleeve and the join body. The triangular flange used for the pipeline is characterized in that the flange body is triangular, flanges are connected through three bolts, rigidity of integral connection is high, under exogenic action, each non-deformability is strengthened, deformation is not easy, flange sealing performance is significantly improved, the problem of leakage caused by deformation of the flanges is resolved, and normal use of a railway vehicle is guaranteed. Two semicircular ladder-shaped split-type clamping sleeves are adopted in the flange body and the joint body, the flange body can be installed and disassembled on the brake pipe freely, and installation and disassembly can be achieved when the diameter of a plate and beam penetrating hole is larger than the outer diameter of the joint body.

Description

A kind of pipeline triangle flange

Technical field:

A kind of pipeline triangle flange belongs to railway vehicle fittings, in particular for connection and the Sealing of brake pipe.

Background technique:

For a long time, brake tube for railway vehicle is poor with the flange sealing, and especially existing 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.

Summary of the invention:

Problem to be solved in the utility model is exactly to provide a kind of pipeline flange that can improve integrated connection rigidity for above deficiency.Its technological scheme is as follows:

It comprises flange body and fittings body, and flange body adopts cutting ferrule to be connected with fittings body, is lined with seal ring between cutting ferrule and the fittings body.Its key technology is that flange body is triangle, and cutting ferrule consists of split type cutting ferrule by minute cutting ferrule and pairing cutting ferrule.

The beneficial effect that compared with prior art the utlity model has is:

1, flange body is triangle, adopts three bolts to connect between the flange, and its integrated connection rigidity is high, under external force, every non-deformability strengthens, and is not yielding, the flange seal performance significantly improves, and has solved the leakage problem that causes because of flange distortion, guarantees the normal use of railway vehicle.

2, flange body adopts cutting ferrule to be connected with fittings body, be lined with seal ring between cutting ferrule and the fittings body, cutting ferrule adopts two semicircle cascade split cutting ferrules, so that the arbitrarily loading and unloading on Brake pipe of flange physical efficiency, plate, beam poling bore dia can load and unload during greater than the fittings body external diameter.

Fig. 2 is Fig. 1 plan view;

Fig. 3 is that the utility model divides cutting ferrule and matched card nested structure schematic diagram;

Fig. 4 is Fig. 3 plan view.

Embodiment:

Such as Fig. 1-shown in Figure 4, the utility model comprises flange body 2 and fittings body 4, and flange body 2 adopts cutting ferrules 1 to be connected with fittings body 4, is lined with seal ring 3 between cutting ferrule 1 and the fittings body 4.Its key technology is that flange body 2 is triangle, is respectively equipped with bolt hole 5 at three angles of flange body 2, so that adopt three bolts to connect between the flange; Cutting ferrule 1 consists of split type cutting ferrule by minute cutting ferrule 1.1 and the pairing cutting ferrule 1.2 of two semicircle stepped shape, and a minute cutting ferrule 1.1 must use jointly with its pairing cutting ferrule 1.2.
