Description

TECHNICAL FIELD

[0001] The utility model belongs to pipeline connecting piece technical field, specifically is waterproof hammer composite combination formula bellows. BACKGROUND

[0002] In fluid transmission systems, bellows are widely used as flexible connecting elements in various pipeline systems to compensate for pipeline displacement caused by temperature changes, pressure fluctuations, or mechanical vibrations.

[0003] For example, a bellows is disclosed in Chinese patent document [Application No. 202020449081.4; Authorized Publication No. CN211351590U], the outer wall of which is composed of convex and concave parts arranged at intervals in the circumferential direction, both of which extend along the axial direction of the bellows, and the straight-line distance from the outer wall of the convex part to the axis of the bellows is greater than that from the outer wall of the concave part to the axis of the bellows.

[0004] The above-mentioned bellows ensures that the bellows has sufficient wear resistance while improving the flexibility of the entire bellows, thereby prolonging the service life of the entire bellows. When the fluid is rapidly switched or the flow direction is suddenly changed, water hammer phenomenon occurs, i.e. the instantaneous pressure fluctuation of the fluid in the pipeline due to inertia. The above-mentioned bellows does not have a water hammer protection structure, and the instantaneous pressure of the fluid in the pipeline increases during the switching of the water valve, and the pressure fluctuation not only produces a loud noise, but also can cause serious impact damage to the pipeline elements such as the bellows, thereby shortening their service life.

The steel wire ring is arranged to support the inner wall of the corrugated pipe, so that the corrugated pipe is kept in an open state, the corrugated pipe will not be bent and depressed, and the support strength of the corrugated pipe is improved.

[0010] In the waterproof hammer composite combined corrugated pipe, a first sealing gasket is arranged on the inner wall of the connecting seat, and the side, away from the inner wall of the connecting seat, of the first sealing gasket is in contact with the first support pipe.

The third sealing gasket is arranged to seal between the connecting seat and the connecting pipe, so as to improve the sealing property between the connecting seat and the connecting pipe.
