Detailed Description

The technical solution of the present invention will be described clearly and completely with reference to the following embodiments, and it should be understood that the described embodiments are some, but not all embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1-3, which is a schematic structural view of a pipeline damper according to a preferred embodiment of the present invention, the structure of the pipeline damper includes a mounting bracket 2 and a damper cylinder 1 fixed on the mounting bracket 2, the damper cylinder 1 is movably assembled with end caps 3 at both sides, the end caps 3 are provided with high-pressure pipe joints 4 for realizing water inlet and outlet functions, a cavity 9 is provided in the damper cylinder 1, a damper sleeve 5 for realizing damping functions is movably assembled in the cavity 9, the damper cylinder 1 is fixedly installed through the mounting bracket 2, the end caps 3 are assembled at both sides of the damper cylinder 1, so that the cavity 9 of the damper cylinder 1 forms a sealed space, the high-pressure pipe joints 4 at both sides of the end cap 3 are respectively a water inlet and a water outlet, when water enters the cavity 9 of the damper cylinder 1 from the water inlet, the damper sleeve 5 is advanced, and at this time, the water is transferred into the damper sleeve 5 due to the vibration generated by pressure pulsation, make this damping sleeve 5 and rivers form resonance, because clearance fit and this damping sleeve 5 have elasticity between damping sleeve 5 and the damper cylinder 1, utilize the elasticity of self to keep apart the vibrations of rivers preferentially to reach the advantage of shock attenuation, noise reduction when increasing the security, the practicality is stronger.

In this embodiment, threaded connection between high-pressure pipe joint 4 and end cover 3, and installing support 2 is fixed in between high-pressure pipe joint 4 and end cover 3, and installing support 2 places in end cover 3 both sides, and high-pressure pipe joint 4 passes installing support 2 and is fixed in on end cover 3 through threaded connection, forms removable movable assembly.

In this embodiment, a second sealing ring 8 is disposed between the high-pressure pipe joint 4 and the end cover 3, and the second sealing ring 8 is disposed at the contact position between the high-pressure pipe joint 4 and the end cover 3, so as to improve the waterproof performance of the two connection positions.

In this embodiment, threaded connection between end cover 3 and damper cylinder 1, and the junction is provided with first sealing washer 6, and end cover 3 is fixed in damper cylinder 1 through the screw thread, forms removable movable assembly, sets up first sealing washer 6 at junction between them and increases waterproof performance.
