The utility model is owing to taking above technological scheme, and it has the following advantages: 1, the utility model is provided with a porous diffusion muffling unit, can realize eliminating the noise to high pressure gas emptying is further auxiliary, and soundproof effect of the present utility model is good.2, the utility model is provided with a vent hood and a drain opening, when rainfall is less, most rainwater directly drains into outside silencing apparatus, when rainfall is larger, major part rainwater drains into outside silencing apparatus together with dust, small part rainwater flows in housing, the rainwater entered in silencing apparatus is discharged eventually through drain opening, can prevent resistance noise reduction unit from blocking, the utility model can play the effect of rain-proof dust-proof.3, the utility model is provided with a resistance noise reduction unit, resistance noise reduction unit is provided with sound-absorbing porous material, sound-absorbing porous material is metal velvet or wire gaze, rainwater can not collect in sound-absorbing material, the drawback that after the utility model can overcome the water inlet of conventional resistance noise reduction unit, soundproof effect reduces.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in detail.
As shown in Figure 1, the utility model proposes a kind of combined type Gas Exhausting Muffle, it comprises a tubular housing 1, and housing 1 inside arranges reducing pressure by regulating flow muffling unit 2 and a micropore jet muffling unit 3.Micropore jet muffling unit 3 is set in the top of reducing pressure by regulating flow muffling unit 2, and bottom is fastenedly connected on the outer wall of reducing pressure by regulating flow muffling unit 2.The top of housing 1 is fastenedly connected a porous diffusion muffling unit 4, for the auxiliary noise elimination of high pressure gas emptying.The bottom of housing 1 is fastened and connected on the outer wall of reducing pressure by regulating flow muffling unit 2.The inwall of housing 1 is fastenedly connected with a resistance noise reduction unit 5, for the auxiliary noise elimination of high pressure gas emptying.
In above-described embodiment, arrange one at the top of housing 1 for water proof and dust proof and in the vent hood 6 of umbrella, can play rainproof effect, small part rainwater enters in housing 1 together with dust when rainfall is larger.Outer wall bottom housing 1 is arranged a drain opening 7 be communicated with housing 1 inside, for being discharged by the rainwater assembling certain liquid level in housing 1.
In above-described embodiment, reducing pressure by regulating flow muffling unit 2 comprises the cylindrical shell 21 of a top closure, bottom end opening, and the bottom end opening of cylindrical shell 21 is connected with former relief opening, and the barrel of cylindrical shell 21 offers multiple through hole 22, and diameter is 3 ~ 6 millimeters.
