Portion is plugged with turns silk valve rod through valve deck, and described turn of silk valve stem top is welded with handle, and described turn of silk valve rod is far from handle
One end is plugged with connection wire rod, and the connection wire rod is installed with flap, the connection wire rod far from the one end for turning silk valve rod
The side of outer wall is installed with draw runner, and the side of the valve deck inner wall offers the sliding slot of cooperation draw runner, the valve body side
Offer inlet, the valve body other side offers liquid outlet, and the valve inner is installed with valve port, outside the valve port
Side is installed with recessed mouth, and the valve inner is installed with check plate close to the side of liquid outlet.
Preferably, the joint of the valve deck and valve body is uniformly bonded with sealant.
Preferably, symmetrically there are two method pulling plates for fixed installation for the valve body both sides, and farad disk both sides symmetrically offer
Two fixing threaded holes.
Preferably, the recessed mouth inner homogeneous is bonded with sealing ring.
Preferably, described turn of silk valve rod coordinates with connection wire rod.
Compared with prior art, the utility model has the beneficial effects that：
1, the utility model can prevent the when of closing check-valves from having liquid reflux, when in use, liquid by the way that check plate is added
Body enters from inlet in valve body, and then liquid is flowed out by valve port from liquid outlet, when close port, the liquid reflux of outflow
Into liquid outlet, the liquid of reflux is isolated in outside check-valves by check plate, the liquid corrosion for protecting check-valves not to be refluxed.
2, the utility model drives connection wire rod rotation by turning silk valve rod, while with draw runner and sliding slot, ensure that
Flap will not rotate during moving down, and improve the tightness of check-valves, when needing close port, be turned by handle rotation
Silk valve rod turns silk valve rod and drives connection wire rod rotation, and draw runner and sliding slot cooperation, to which connection wire rod drives flap to moving down
Dynamic, then flap is connected to recessed mouth, and such flap is tightly contacted with recessed mouth, ensure that the tightness of check-valves.

Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
- 3 are please referred to Fig.1, the utility model provides a kind of technical solution：A kind of check-valves of anti-suck, including 1 He of valve deck
Valve body 2, the valve deck 1 are fixedly connected with valve body 2 by locking nut 3, and 1 top of the valve deck is installed with bearing 6, the axis
It holds to be plugged with inside 6 and turns silk valve rod 7 through valve deck 1, described turn of 7 top of silk valve rod is welded with handle 5, described turn of silk valve rod 7
