Description

Exhaust pipe clamp type fastening sealing structure

Technical Field

The utility model relates to an engine exhaust technical field especially relates to an exhaust pipe strap formula fastening seal structure.

Background

At present, exhaust pipes of cylinders on an exhaust system of a high-power engine are connected and fastened through a corrugated pipe and a sealing gasket by bolts through the corrugated pipe and a square flange on the exhaust pipe, however, after the exhaust pipe and the corrugated pipe of the exhaust system of the high-power gas engine are connected and fastened by the square flange, after the engine runs for a period of time, the exhaust temperature is high, so that the square flange on the exhaust pipe and the corrugated pipe deforms seriously at a non-bolt fastening position, the joint surface of the flange is not sealed tightly, and air leakage is caused, and therefore, an exhaust pipe clamp type fastening sealing structure is provided.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the defects existing in the prior art and providing an exhaust pipe clamp type fastening and sealing structure.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides an exhaust pipe strap formula fastening seal structure, includes the bellows, bellows both ends symmetry is provided with the blast pipe, the bellows all overlaps with two blast pipe junctions and is equipped with the pipe strap.

Preferably, circular flanges are arranged at two ends of the corrugated pipe, and the circular flanges are arranged at one ends of the two exhaust pipes close to the corrugated pipe.

Preferably, two pipe clamps are internally provided with grooves matched with the circular flange at the pipe orifice of the corrugated pipe and the circular flange at the pipe orifice of the exhaust pipe.

Preferably, the pipe clamp comprises two semicircular clamp bodies, one end of each clamp body is hinged, and one end, far away from the hinged position, of each clamp body is fixed through a bolt.

The utility model has the advantages that:

1. square flanges of the exhaust pipe and the corrugated pipe are changed into circular flanges, so that the stress is more uniform;

2. the flange of junction cancels bolted connection, adopts the pipe strap to connect and fasten the junction flange of bellows and blast pipe, makes two flange fastening back atresss evenly, and the back non-deformable that is heated has improved the sealed reliability of exhaust duct, and the connection through the pipe strap is installed firmly moreover, and connection stability is good.

Drawings

Fig. 1 is a schematic cross-sectional structure view of an exhaust pipe clamp type fastening sealing structure provided by the present invention;

fig. 2 is a schematic view of a clamp-type fastening sealing structure of an exhaust pipe according to the present invention.

In the figure: 1 corrugated pipe, 2 pipe clamps and 3 exhaust pipes.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1, an exhaust pipe clamp formula fastening seal structure, including bellows 1, bellows 1 both ends symmetry is provided with blast pipe 3, and bellows 1 all overlaps with two blast pipe 3 junctions and is equipped with pipe clamp 2.

The utility model discloses in, 1 both ends of bellows all are equipped with circular flange, and two blast pipes 3 all are equipped with circular flange near the one end of bellows 1, all are equipped with in two pipe strap 2 with the recess of the circular flange looks adaptation of the mouth of pipe department of bellows 1 and the mouth of pipe department of blast pipe 3, and pipe strap 2 includes two semicircular clamps, and one of them end of two clamps is articulated mutually, and two clamps keep away from the one end of articulated department and pass through the bolt fastening.

The working principle is as follows: open the bolted connection department of two pipe clamps 2 earlier during the use, then place the circular flange at bellows 1 both ends in the recess on two pipe clamps 2, then place the circular flange of two blast pipes 3 one ends respectively in two pipe clamps 2, make bellows 1 and blast pipe 3 closely laminate in the recess on pipe clamp 2, it is fixed with 2 opening parts of pipe clamp with the bolt at last, thereby make the stress after the flange fastening of bellows 1 and blast pipe 3 even, be heated non-deformable, the sealed reliability of exhaust duct has been improved.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
