Specific embodiment
As shown in Figure 1 to Figure 3, a kind of gate valve, including valve body 1, valve deck 2, valve plate 3, connecting rod 4, eccentric wheel 5 and handwheel 6.Valve
Body 1 and valve deck 2 by flange and are bolted fastening, adjusting cavity 7 are formed with inside valve body 1 and valve deck 2, eccentric wheel 5 is by turning
Axis 8 is installed in adjusting cavity 7, and shaft 8 is prejudicially keyed eccentric wheel 5, and eccentric wheel 5 can adjusted by the transmission of shaft 8
Eccentric rotary in chamber 7.Valve body 1 is equipped with axis hole, is equipped with bearing 9 in axis hole, shaft 8 is horizontally installed in bearing 9, shaft
8 end is welded and fixed after stretching out axis hole with handwheel 6.The upper and lower ends of connecting rod 4 are hingedly connected on eccentric wheel 5 and valve plate 3；Valve
It is equipped with feed liquor runner 10 and out liquid stream road 11 in body 1, valve plate slot 12, eccentric wheel are equipped between feed liquor runner 10 and out liquid stream road 11
When 5 rotation, valve plate 1 can be driven to move up and down along valve plate slot 12 by connecting rod 4, to be turned on or off gate valve.Valve plate slot
12 height setting are as follows: when valve plate 3 is thus lifted to highest point, the bottom end of valve plate 3 is still protruded into valve plate slot 12, without departing from
Valve plate slot 12, therefore the bottom end of valve plate 3 is limited in always in valve plate slot 12, is steadily back and forth moved along valve plate slot 12 convenient for it
It is dynamic.
As shown in figure 3, valve deck 2 is equipped with latch 13, latch 13 is solderable to be connected on valve deck 2, can also be with valve deck 2 one
It is body formed.Latch 13 is located at the surface of shaft 8, is equipped with vertical pin hole in latch 13；Vertical lock is equipped in shaft 8
Hole, lockhole are located at the underface of pin hole, and major part pin 14 can be sequentially inserted into pin hole and lockhole, the diameter of major part pin 14 simultaneously with
The diameter of pin hole and lockhole matches, major part pin 14 shaft 8 can be locked in standard-sized sheet or the rotation angle closed entirely on, avoid turning
Axis 8 is freely rotated and causes to malfunction.
The word indicating for being printed on standard-sized sheet on handwheel 6 and closing entirely, standard-sized sheet or the text closed entirely when valve wide open perhaps full pass
12 o'clock that word mark turns to handwheel respectively on position, indicates the switch state of valve plate with further clarifying.
The seal receptacle 15 of annular is fixed in valve plate slot 12, two seal receptacles 15 are oppositely arranged, the left and right sides wall of valve plate 3
Seal receptacle 15 is abutted respectively, and seal receptacle 15 improves the sealing performance between valve plate 3 and valve plate slot 12, and seal receptacle 15 is to valve
Auxiliary guiding is played the role of in moving up and down for plate 3, guarantees that valve plate 3 accurately moves in valve plate slot 12.Seal receptacle 15 it is interior
The diameter of ring diameter, the diameter of feed liquor runner 10 and liquid stream road 11 out is all the same, therefore seal receptacle 15 will not protrude from runner
And fluid is influenced in the intracorporal proper flow of valve.
The course of work of this gate valve are as follows: when needing to open gate valve, remove major part pin 14, rotate handwheel 6, handwheel 6 drives
Shaft 8, eccentric wheel 5 and connecting rod 4 rotate, and then valve plate 3 is driven to move up in valve plate slot 12, when the word indicating of standard-sized sheet turns
When moving to 12 o'clock position, stop operating handwheel 6, and major part pin 14 is inserted into latch 13 and shaft 8 and locks handwheel 6, at this time
Valve plate 3 is moved to highest point, valve wide open.When needing closing gate valve, major part pin 14 is removed, handwheel 6 is clockwise or inverse
Hour hands rotate 180 °.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, although referring to aforementioned reality
Applying example, invention is explained in detail, for those skilled in the art, still can be to aforementioned each implementation
Technical solution documented by example is modified or equivalent replacement of some of the technical features.It is all in essence of the invention
Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
