Description

Loine pressure fluctuates damper
Technical field
The present invention relates to fluid delivery pipeline system noise reduction technology field, specifically a kind of loine pressure fluctuation abatement Device.
Background technology
Pressure fluctuation caused by power source, compression shock and pipeline caused by system condition conversion in fluid delivery system Pressure oscillation caused by break-make is all easily propagated along the fluid in pipeline, has a strong impact on the workability of devices in system and annex Energy and service life.
The content of the invention
It is an object of the invention to overcome above-mentioned deficiency, there is provided a kind of loine pressure fluctuates damper, can effectively significantly The peak value of fluid pulsation is reduced, ensures the service behaviour of equipment and annex, increase the service life.
To realize above-mentioned technical purpose, scheme provided by the invention is:A kind of loine pressure fluctuation damper, including located at Cylinder in pipeline, the axis direction of cylinder is fluid cavity, set gradually between fluid cavity and cylinder inboard wall damping oil pocket and Compressed air cell, separated between fluid cavity and damping oil pocket by elastic inner membrane, damping oil intracavitary sets damping orifice plate group, compression Air chamber includes elastic air pad, the elastic air pad and pressurising and the pressure detecting fittings for being arranged at cylinder body outer wall, cylinder Body both sides are connected through a screw thread inner flange and sealed by O-ring and back-up ring, and inner flange coordinates with elastic inner membrane to be realized Damp oil pocket sealing, at least the inner flange of side be provided with damping oil pocket connect and be provided with plug through hole, both sides it is interior Flange is connected by circumferential uniform bolt and the outward flange for connecting upstream and downstream pipeline respectively.
Moreover, damping orifice plate group includes multilayer tubular plate with holes, connection damping orifice plate group between every layer of tubular plate be present The gap of inside and outside damping oil pocket, the damping oil of damping oil intracavitary can flow in the aperture in damping orifice plate group and gap.
Moreover, elastic air pad includes the air-cushion unit of multiple intercommunications.
The beneficial effects of the present invention are:It is simple in construction, it is skillfully constructed;Damping orifice plate group can be by rubbing fluid Pressure fluctuation energy is converted into heat energy;Equivalent to one accumulator of the compound action of elastic air pad and elastic inner membrane, Ke Yiyou Effect reduces the peak value of fluid pressure fluctuations.

Embodiment
Below in conjunction with the accompanying drawings and embodiment the invention will be further described.
The present embodiment provides a kind of loine pressure fluctuation damper, as depicted in figs. 1 and 2, including the cylinder in pipeline Body 6, the axis direction of cylinder 6 is fluid cavity, and damping oil pocket and compressed air are set gradually between fluid cavity and the inwall of cylinder 6 Chamber.
Separated between fluid cavity and damping oil pocket by elastic inner membrane 9.Elastic inner membrane 9 is used for fluid cavity and damping oil pocket Separate, and the pressure oscillation in fluid cavity is delivered to damping oil pocket.
Damping oil intracavitary sets damping orifice plate group 8, and damping orifice plate group 8 includes multilayer tubular plate with holes, every layer of tubular plate Between the gap of damping oil pocket inside and outside connection damping orifice plate group 8 be present, the damping oil of damping oil intracavitary can be in damping orifice plate Flowed in aperture and gap in group 8.Kinetic energy is changed into heat energy by damping oil when being flowed in damping orifice plate group 8, by rubbing.
Compressed air cell includes elastic air pad 7, and elastic air pad 7 includes the air-cushion unit of multiple intercommunications.The elasticity is empty Air cushion 7 connects with the pressurising and pressure detecting joint 5 for being arranged at the outer wall of cylinder 6, can be as needed from pressurising and pressure detecting Gas is filled with joint 5 into elastic air pad 7, and detects the pressure in elastic air pad 7.
The both sides of cylinder 6 are connected through a screw thread inner flange 12 and sealed by O-ring 10 and back-up ring 11, inner flange 12 Coordinate the sealing for realizing damping oil pocket with elastic inner membrane 9.
At least the inner flange 12 of side is provided with connects and is provided with the through hole of plug 13 with damping oil pocket, assembles outward flange 4 Before, by the through hole on inner flange 12, damping oil will be filled in damping oil pocket.
The inner flange 12 of both sides connects upstream and downstream by circumferential uniform bolt 1, spring pad 2, pad 3 with being used for respectively The outward flange 4 of pipeline connects.
The combination of elastic air pad 7 and elastic inner membrane 9, the peak value of fluid pulsation can effectively be greatly reduced.
Described above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art For member, under the premise without departing from the principles of the invention, some improvement or deformation can also be made, these are improved or deformation also should It is considered as protection scope of the present invention.
