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. 1-3, the present invention provides an embodiment: an intelligent water hammer-proof valve comprises a valve cover 5, a piston body 3 and a valve body 16, wherein both sides of the top end of the valve body 16 are fixedly connected with the valve cover 5 through second fastening bolts 14, a throttling cavity 7 is arranged at the top end of the valve cover 5, a throttling pad 8 is arranged between the inner walls of both sides of the throttling cavity 7, the top end of the throttling pad 8 is uniformly provided with a first round hole 13, a dustproof net 12 is arranged at the outer side of the throttling cavity 7, both sides of the top end of the dustproof net 12 are fixedly connected with a protective cover 9 through first fastening bolts 11, a second sealing pad 10 is arranged at the bottom end of the protective cover 9, an outer sleeve 4 is arranged at the top end inside the valve cover 5, the piston body 3 is arranged between the inner walls of both sides of the outer sleeve 4, a compression spring 2 is arranged at the bottom end of the piston body 3, the bottom end, the top of outer tube 4 is provided with lid 15, and the central point on lid 15 top puts the department and is provided with exhaust hole 22, locating lever 21 is installed on the top of lid 15, and the both sides of locating lever 21 all are provided with first sealed pad 6, install blotter 1 between the valve body 16 both sides inner wall of outer tube 4 below, and the top of blotter 1 evenly is provided with second round hole 18, the below of valve body 16 one side is provided with washing wash port 17, hydraulic sensor 20 is all installed to the both sides of valve body 16 bottom, the central point of valve body 16 bottom puts the department and installs induction door 19.
