Specific embodiment
Please join shown in Fig. 1 to Fig. 6, present invention discloses a kind of gas exhausting valve 100, can be applied to exhaust silencer or
In person's exhaust pipe.The gas exhausting valve 100 includes the shell 1 of tubulose, the valve deck 2 being covered on the shell 1, across described
The shaft 3 of shell 1 and the valve deck 2, be fixed in the shaft 3 with the shaft 3 together rotary motion valve block 4, with
And the spring 5 matched with the shaft 3.
In illustrative embodiments of the present invention, the shell 1 is equipped with notch 11, and the valve deck 2 is described including being covered on
Main part 21 on notch 11 and the extension 22 from 21 bending of main part formation.The extension 22 is in tabular.
The extension 22 is equipped with the basic courses department 221 close to the shell 1 and the end 222 far from the shell 1, the basic courses department
221 is wider than the end 222, so that the extension 22 be made to have enough intensity.
One end of the spring 5 is fixed on the extension 22, and the other end is fixed in the shaft 3.
In illustrative embodiments of the present invention, the two sides of the main part 21 are equipped with protrusion 211 and through described convex
Play 211 complete perforation 212.The gas exhausting valve 100 further includes being respectively positioned in the perforation 212 from inside to outside
Two bushings 6.Each bushing 6 includes base portion 61 and the contraction flow region 62 being housed in the perforation 212.The shaft 3 is worn
Cross the bushing 6.
The valve block 4 includes the steel wool protective case 42 of valve block portion 41 and the bottom positioned at the valve block portion 41.It is described
Steel wool protective case 42 is socketed in the valve block portion 41, wherein the steel wool protective case 42 is equipped with the opposite make-up extended
