Abstract

The utility model discloses an amortization apparatus for the gas holder intake check valve of air compressor. By connecting the utility model with the gas holder intake check valve of air compressor, the shell body comprises an upper cover, an amortization body and a bottom cover; the lower end of upper cover is fixed with the upper port of amortization body, the bottom cover is fixed with the lower port of amortization body, the filter mesh that is tube shape and a plurality of small holes on round wall is arranged at the center of amortization body; and sponge is arranged between the inside wall of amortization body and outer wall of filter mesh, a plurality of through holes are arranged on the bottom cover. Utilizing the cavity with sponge and filter mesh buffers, filters and absorbs the gas into the gas holder through the check valve to arrive the efforts of reducing noise, which makes the noise value of check valve to reduce more than 5 decibels; the utility model has the advantages of less components, convenient manufacturing and using, low costs and easy to popularize.

Description

Air compressor air storage tank one-way valve silencer

Affiliated technical field

The utility model relates to air compressor accessory field, particularly a kind of air compressor gas holder one-way valve silencer.

Background technique

At present, no matter oily air compressor is arranged or oil-free air compressor gas holder breather check valve place all is not provided with silencer, cause air compressor when work because pressure surge one-way valve snap switch sends very big noise, become important noise source of air compressor, have a strong impact on surrounding environment, also have influence on the use of air compressor.

Summary of the invention

In order to reduce the noise of air compressor gas holder one-way valve, the utility model provides a kind of silencer, and this silencer can make the noise of breather check valve obviously reduce.

The technical scheme in the invention for solving the technical problem is: connect the utility model under air compressor gas holder breather check valve, housing is made up of loam cake, muffler body, bottom, loam cake lower end and muffler body are suitable for reading fixing, bottom and muffler body end opening are fixed, tubulose and perisporium are housed in the middle of the muffler body the filter screen of a lot of apertures, between muffler body inner circle wall and filter screen periphery wall, be full of sponge, be shaped on some through holes on the bottom.

The transition portion that exports that enters the mouth in the described loam cake has a cavity, is little-big-minor structure from import to outlet.

The residing position of through hole on the described bottom is corresponding with filter screen at the middle part.

The beneficial effects of the utility model are, the cavity that utilizes band sponge and filter screen to the gas that enters gas holder through one-way valve cushion, filtration, sound-absorbing, reach the effect that reduces noise, make the level of noise of one-way valve reduce more than 5 decibels: used element is few, manufacturing and use are all very convenient, cost is low, is easy to promote the use of.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the new longitudinal section view of this practicality.

Fig. 2 is the worm's eye view of Fig. 1.

1. loam cakes among the figure, 2. muffler body, 3. sponge, 4. filter screen, 5. bottom.

Embodiment

In Fig. 1, Fig. 2, the profile of whole silencer is the bottle shape, loam cake (1) oral area is connected with one-way valve with internal thread, the transition portion that exports that enters the mouth to inward again is a buffering cavity, wherein central passage is the most spacious, be little-big-minor structure from import to outlet, in order to subdue and to cushion the first wave sound sound; Sound-absorptive object (2) is suitable for reading to be fixed with loam cake (1) lower end, sound-absorptive object (2) inner circle wall is sound-absorbing sponge (3), it in sponge (3) filter screen (4) that the periphery of tubulose has a lot of apertures, bottom (5) is fixed on the bottom of sound-absorptive object (2), at the middle part of bottom (5) and filter screen (4) to 9 uniform apertures should be arranged, certainly, the aperture of aperture and quantity can be appraised and decided variation according to air-flow.Like this, just build the cavity of a buffering, filtration, sound-absorbing, further subdue and cushion noise, reach and reduce the purpose that one-way valve opens and closes the noise that causes, make the one-way valve level of noise reduce more than 5 decibels on original basis.

Claims

1. air compressor gas holder one-way valve silencer, housing is made up of loam cake, muffler body, bottom, and loam cake lower end and muffler body are suitable for reading fixing, and bottom and muffler body end opening are fixed.It is characterized in that: the filter screen that tubulose and perisporium have a lot of apertures is housed in the middle of the muffler body, between muffler body inner circle wall and filter screen periphery wall, is full of sponge, be shaped on some through holes on the bottom.

2. air compressor gas holder one-way valve silencer according to claim 1 is characterized in that: the transition portion of the outlet that enters the mouth in the described loam cake has a cavity, is little-big-minor structure from import to outlet.
