Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, an air type pulse damper comprises a damper body 1, a water inlet pipe 3 is fixedly communicated with the bottom end of the damper body 1, a fixing rod 6 is fixedly connected with the top end of the inner cavity of the water inlet pipe 3, a first spring 5 positioned in the inner cavity of the water inlet pipe 3 is fixedly connected with the bottom end of the fixing rod 6, a sealing sheet 4 is fixedly connected with the bottom end of the first spring 5, the sealing sheet 4 is made of rubber, the sealing sheet 4 is movably sleeved with an air inlet cavity 7, the left side of the damper body 1 close to the top end is fixedly communicated with the air inlet cavity 7, a handle 8 is movably sleeved in the air inlet cavity 7, the right end of the handle 8 penetrates through the air inlet cavity 7 and the damper body 1, a diaphragm 9 is fixedly connected with the right end of the handle 8, the diaphragm 9 is positioned in the inner cavity of the damper body 1, a second spring 10 is fixedly sleeved on the outer surface of the handle 8, and the right end, when the second spring 10 is in the longest compression state, the diaphragm 9 is tightly attached to the right end of the air inlet cavity 7, and when the second spring 10 is compressed, the diaphragm 9 is separated from the right end of the air inlet cavity 7.
