In the application; The utility model is connected in the pipeline of pressure medium flow through housing; Medium gets into from the medium import, and through middle part water conservancy diversion and shunting on the conducting element, medium spreads to housing inner outlet direction; And after the over commutation through hole gets into the silencing cavity noise reduction, flow to media outlet, flow out through media outlet at last.In the whole process, flowed out because disorderly pressure medium shunts, form the current stabilization state after the rectification, noise reduction, noise is effectively reduced with vibration, and can adapt to different noise reduction demands through the quantity of adjustment commutator lug and silencing cavity.
Further, said conducting element is the circular arc cone to the end, middle part of a side evagination of said medium import.Convection cell, circular arc streamline are the minimum a kind of form structure of the pressure loss.
Particularly, said water conservancy diversion through hole and said rectification through hole are one or more in circular port, square opening, bar hole and the camber line shape hole, in water conservancy diversion, rectification, can increase the volume of medium circulation as far as possible, reduce the pressure loss.
Further, said commutator lug is to be provided with the annulus that is connected with the inwall of said housing between the outward edge of a plurality of, adjacent said commutator lug, and adjacent said commutator lug forms silencing cavity jointly with corresponding annulus.One group of commutator lug of every increase and silencing cavity just further improve erasure effect.
According to the practical application needs, the thickness of different said commutator lugs can be similar and different; Different said silencing cavity can be similar and different at the thickness of the axial direction of said housing.
Further, said housing comprises main casing and the housing end plug that is tightly connected each other and is convenient to adorn, tears open, and said conducting element, said commutator lug all are installed on the inwall of said main casing; Adopt between said housing end plug and the said main casing and be threaded.This is to be convenient to install and remove parts such as commutator lug according to actual needs fast and the structure that designs; In operation; Only need main casing and housing end plug are taken apart, parts such as installation or removal commutator lug, conducting element, annulus at an easy rate, and then main casing is connected with housing end plug gets final product.
Further, the joint between said housing end plug and the said main casing is provided with elastomer seal, and this structure can guarantee the positive confinement between housing end plug and the main casing, and the pressure medium that in housing, circulates can not leaked.
The beneficial effect of the utility model is:
The utility model is shunted the manifold pressure medium through conducting element is set, and avoids its concentrated punching press and forms the high-decibel noise; And make pressure medium change the current stabilization state into from turbulent condition through commutator lug and silencing cavity are set, reduced noise effectively; Because the quantity of commutator lug and silencing cavity can be regulated,, changed a noise reduction pattern of conventional pipelines rectification baffler so its effect that reduces noise also can be regulated as requested.Novel not only have better erasure effect, and can change erasure effect according to actual needs to adapt to actual demand.
