Abstract
The utility model discloses a multi-layer filtering easing valve with a silencing pipe comprising a valve body and a silencer arranged on the valve body. The valve body has an air outlet and an air inlet of a pressure regulating valve. The silencer comprises an encloser and a filter element; the encloser has an air suction port. The valve body is equipped with a support valve cap provided with a valve stem started by off-loading. The utility model is characterized in that the channel end connected with the air inlet of the pressure regulating valve is provided with the piston mechanism; a corresponding open-close hole is arranged in the interior of the support valve cap and on the upper end of the sealing face of the piston mechanism; the air suction port on the encloser is connected with the silencing pipe arranged inside the encloser. The beneficial effect of the utility model is that the structure is novel and unique, simple and practical; the design is ingenious and rational; the movement is steady and reliable; the sealing is good; particularly the noise cancellation effect is good; and the life length is long; the cost is low.
