With keying reliability.
Description of the drawings
Fig. 1 is irrigation canals and ditches pendulum valve structural schematic diagram provided by the utility model；
Fig. 2 is the vertical view of Fig. 1.
Specific implementation mode
The embodiment of the present application by providing a kind of irrigation canals and ditches pendulum valve, solve irrigation canals and ditches valve corrosion in the prior art cause it is close
The technical issues of envelope effect is poor, keying poor reliability.
In order to better understand the above technical scheme, in conjunction with appended figures and specific embodiments to upper
It states technical solution to be described in detail, it should be understood that the specific features in the utility model embodiment and embodiment are to this Shen
Please technical solution detailed description, rather than to the restriction of technical scheme, in the absence of conflict, the application is real
The technical characteristic applied in example and embodiment can be combined with each other.
Referring to Fig. 1 and Fig. 2, irrigation canals and ditches pendulum valve, including：
Valve frame 1 and matching swing valve plate 3, the swing valve plate 3 are resisted against in the valve frame 1；
It is pressed in the valve frame 1 by swinging valve plate 3, realizes valve locking；By swinging valve plate 3 far from the valve frame
1 realizes valve opening.
Crank and rocker mechanism, including：Swing link bracket 4, crank 6, rocking bar 7 and connecting rod 5；The swing link bracket 4 is fixed on
In the valve frame 1, the first end of the first end of the crank 6 and the rocking bar 7 is hinged with the swing link bracket 4, described
The second end of crank 6 and the second end of the rocking bar 7 are hinged with the connecting rod 5, and the connecting rod 5 is fixed with the swing valve plate 3
It is connected；It realizes that swing valve plate 3 is separate relative to valve frame 1 and digs by crank and rocker mechanism, realizes convenient-opening；Simultaneously
Also avoid grain slag of the gate valve due to accumulation, caused keying is difficult the problems such as corrosion, seals insecure problem.
Axially driving structure 9 and driving arm 2, the driving arm 2 are fixed in the valve frame 1, the axis
It is hinged on the driving arm 2 to 9 bottom of driving structure, axially driving end is hinged with the swing valve plate 3.Generally by
It is hinged with 9 top of axially driving structure that articulated base 8 is fixed on swing valve plate 3, realizes flexible connection.
