Detailed description of the invention
Clearer for the purpose making the present invention implement, technical scheme and advantage, below in conjunction with in the embodiment of the present invention
Accompanying drawing, the technical scheme in the embodiment of the present invention is further described in more detail.In the accompanying drawings, the most identical or class
As label represent same or similar element or there is the element of same or like function.Described embodiment is the present invention
A part of embodiment rather than whole embodiments.The embodiment described below with reference to accompanying drawing is exemplary, it is intended to use
In explaining the present invention, and it is not considered as limiting the invention.Based on the embodiment in the present invention, ordinary skill people
The every other embodiment that member is obtained under not making creative work premise, broadly falls into the scope of protection of the invention.Under
Face combines accompanying drawing and is described in detail embodiments of the invention.
In describing the invention, it is to be understood that term " " center ", " longitudinally ", " laterally ", "front", "rear",
The orientation of the instruction such as "left", "right", " vertically ", " level ", " top ", " end " " interior ", " outward " or position relationship are for based on accompanying drawing institute
The orientation shown or position relationship, be for only for ease of and describe the present invention and simplify description rather than instruction or the dress of hint indication
Put or element must have specific orientation, with specific azimuth configuration and operation, therefore it is not intended that protect the present invention
The restriction of scope.
Below in conjunction with the accompanying drawings embodiments of the invention are described in detail.Refer to Fig. 1；
A kind of damping muffler with radial-axial compensation function, by inlet ductwork joint 1, rectifier tube 2, inner corrugated pipe
3, outward corrugated tube 4, reservoir-antivibrator 5, limit pull rod 6, spacing bulb 7, export pipeline joint 8, damping fluid 9, crossbeam 10, sky
Chamber 11 forms；
Come from the highly pressurised liquid of pump in flow process, flowed into by rectifier tube 2 and ripple in flexible pressure-resistant by rectifier tube 2
In the open cavity body that stricture of vagina pipe 3 is welded to form, so the energy of fluid reduces in pipeline, enter the fluid forces in open cavity body soft
