The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0025] like Figures 1 to 4 As shown, the utility model is an impulse generator set speed governor with a pipeline protection structure, comprising a speed governor body 1 and a pressure pipeline 2, the speed governor body 1 is provided with a pressure pipeline interface 3, the pressure pipeline interface 3 is provided with a protection structure, the protection structure comprises a shock-absorbing pad and a protective cover, the protective cover is arranged on the pressure pipeline interface 3, the protective cover comprises an inner tube 4 and an outer tube 5, a shock-absorbing layer is provided between the inner tube 4 and the outer tube 5, a plurality of shock-absorbing members 8 are arranged in the shock-absorbing layer, the shock-absorbing pad is provided on the inner side of the inner tube 4, and a plurality of downflow grooves 9 are provided around the inner side of the inner tube 4.

[0026] The pipeline protection structure of the utility model: the speed regulator is provided with a protection structure at the pressure pipeline interface 3, including a shock-absorbing pad and a protective cover. The shock-absorbing pad is made of elastic material. When the fluid in the pressure pipeline generates impact and vibration, the shock-absorbing pad can effectively absorb these impacts and vibrations, reducing the impact on the precision parts inside the speed regulator. The diameter of the protective cover gradually expands from one end to the other end, and the end with a wide diameter is adapted to the pressure pipeline interface 3 of the speed regulator body 1, which can effectively prevent the pressure pipeline interface 3 from being collided with and damaged by external objects.

[0027] The internal design of the pressure pipeline of the utility model: a plurality of flow-reducing grooves 9 are arranged in the pressure pipeline, which helps to slow down the fluid speed and pressure, thereby reducing the impact, and further reducing the impact of fluid impact and vibration.

[0028] The fixing structure of the utility model: fixing rings 6 are installed at both ends of the protective cover, and these fixing rings 6 are connected with the inner tube 4, the pressure pipeline interface 3 and the pressure pipeline 2 through a threaded structure, thereby ensuring the stability and sealing of the protective structure.

[0029] The design of the shock absorber 8 of the utility model: the shock absorber 8 includes a telescopic rod 10 and a buffer spring 11, and the buffer spring 11 is sleeved on the outside of the telescopic rod 10. When the fluid impact occurs, the telescopic rod 10 and the buffer spring 11 work together to improve the elasticity of the protective cover, absorb the impact force of the water flow, and further protect the internal components of the speed regulator. The shock absorber 8 is assembled with the outer tube 5 and the inner tube 4 through the slide rod 12 and the slide groove 7, which is convenient for disassembly, assembly and replacement for later maintenance.

[0030] Working principle of the protective cover in the impulse generator set speed governor with pipeline protection structure:

[0031] Structure and materials: The protective cover is composed of an inner tube 4 and an outer tube 5, with a shock-absorbing layer arranged between the inner tube 4, the outer tube 5 and the shock-absorbing pad are all made of elastic materials, which can produce a certain deformation when impacted, thereby absorbing the impact energy.

[0032] Shock-absorbing layer and shock-absorbing member 8: Several shock-absorbing members 8 are arranged in the shock-absorbing layer, and each shock-absorbing member 8 includes a telescopic rod 10 and a buffer spring 11. When the fluid in the pressure pipeline vibrates, the telescopic rod 10 and the buffer spring 11 work together to improve the elasticity of the protective cover, absorb the impact force of the water flow, and further protect the internal components of the governor.

[0033] Gradual diameter design: The diameter of the protective cover gradually expands from one end to the other. This design can effectively disperse and resist external impacts and collisions, thereby improving the protective effect.

[0034] Working principle of fixing ring 6:

[0035] Structure and connection: Fixing rings 6 are installed at both ends of the protective cover, and these fixing rings 6 are respectively connected to the inner tube 4, the pressure pipeline interface 3 and the pressure pipeline 2 through threaded structures. This design enables the protective structure to be firmly installed on the speed governor, and is convenient for subsequent disassembly and maintenance.
