Below with reference to the accompanying drawings and in conjunction with the embodiments describing this utility model in detail.
As depicted in figs. 1 and 2, the silence valve of a kind of pair of non-return structure includes：Non-return buffering cavity 10, outlet duct portion 11,
Inlet tube expansion section 20, check-valves guide part 200, import pipe portion 21, first check-valve 30, second check-valve 32, elastic component 40,
The non-return buffering cavity 10 is located at 11 central axis of outlet duct portion, cylindrical shape of the non-return buffering cavity 10 in single sealing, in cylinder
Elastic component 40 is provided with, non-return buffering cavity 10 is externally provided with the directed cavity 13 of damming being oriented to of damming, and directed cavity of damming 13 is in without envelope
The cylindrical shape of mouth, directed cavity of damming 13 are connected with outlet duct portion 11 by connecting portion 12, and non-return buffering cavity 10 is set in and cuts
In stream directed cavity 13, non-return buffers cavity 10 and vertical 10 connecting portion of non-return cavity that dams that pass through between directed cavity 13 that dams
130 connections, disperse medium, 40 one end of the elastic component are fixed in non-return buffering cavity 10, the other end and first check-valve 30
Connection, first check-valve 30 are cylindrical, are made using the resistance to rotten on-deformable material of lightweight, expand through inlet tube is fixed on
The check-valves guide part 200 in the exit in big portion 20, by check-valves connector between first check-valve 30 and second check-valve 32
31 connections, the sectional dimension of check-valves connector 31 are less than the sectional dimension of first check-valve 30, and second check-valve 32 is in cavity
Hemispherical, flange 110 direction of the inner chamber towards import pipe portion 21, hemispherical interior chamber size more than expansion section entrance 210 chi
It is very little, portion's entrance 210 can be will be enlarged by and covered comprehensively, described inlet tube expansion section 20 expansion section entrance 210 and expands in spherical
