Technical field
Theme of the present disclosure relates to the noise attentuation in fluid coupling (such as, valve or flow regulator).
Background technique
The flowing through fluid coupling of working fluid (such as gas and liquid) can produce disadvantageous operational condition.The change striden across on the pressure of the working fluid of fluid coupling can cause causing the hydrodynamic of noise, heat and mechanical vibration.The noise of gained can reach far above 100dba, and often exceeds the regulation the received exposure of the noise in operational site being arranged to restriction.
Some fluid couplings comprise the device that can address these problems.Working fluid is directed across the passage being formed and have multiple zigzag path turned to by these devices.This passage is such as by little by little becoming kinetic energy by the potential energy in working fluid and weakening noise level.But in many fluid couplings, throttle element (such as, dividing plate) is arranged on passage proximate.This structure of throttle element can reduce effect of attenuating device because throttle element can prevent working-fluid flow from passing in the passage of attenuating device some.
All exploitable channels can not be utilized also can to reduce the life-span of these devices.Usually, passage operates all the time under peak rate of flow condition (such as, top speed), only exposes the passage of limited quantity because this structure of throttle element depends on volume and/or other flox condition.Thus, these flox conditions can accelerate especially to occur those passages following wearing and tearing, corrosion and other infringement, those passages all receive fluid stream in throttle element part with when opening completely.
Summary of the invention
Present disclosure describes the improvement of the noise attentuation for fluid coupling, it especially solves wear problem with cost-efficient design.As below propose, sound attenuation is separated with throttle element by these improvement.The gap of gained and/or interval allow working fluid (such as gas and liquid) to flow through all passages in all positions of throttle element.In addition, sound attenuation strides across passage relative to the position of throttle element and divides flow equably, thus the liquid speed management in each passage is extremely reduced the level of abrasion and corrosion infringement.
The structure of the embodiment of sound attenuation utilizes multiple plates with opening, and the plurality of plate forms the structure of passage when being arranged together.Passage comprises multiple turning to, and turns to and makes the change of the direction of stream reduce noise.But these devices adopt the plate of the assembling simplifying passage.In one embodiment, sound attenuation only needs the plate of two types.All types of plate features is the different patterns of opening.And based on geometrical shape and the layout of opening, the embodiment of sound attenuation can comprise lit-par-lit structure, its plate is positioned to only two orientations to form passage.This feature helps avoid the incorrect orientation that correctly can not form the passage that working fluid can flow through.
