Connecting bracket 4, the connecting bracket 4 are arranged on the inner wall of valve body 1；
Linking arm 5, the linking arm 5 are fixedly connected in the connecting bracket 4, and the linking arm 5 and valve plate device 7 are logical
It is hinged to cross the first connecting shaft 6, first connecting shaft 6 valve in 72 left end face of valve plate in valve plate device 7 and valve plate device 7
Between 72 center line of plate；
The valve plate device 7, which has, to be sealed with 2 phase of valve seat so that the closed position that Y shape runner 11 is closed, the valve plate dress
Setting 7 also has around the rotation of the first connecting shaft 6 so that the open position of the Y shape runner 11 circulation；
The valve seat 2 is set in the mounting groove 12, and the valve seat 2 is cone with the inner surface at 7 phase sealing of valve plate device
Face, the valve seat 2 are being equipped with annular mounting recess 21 with the outer surface at 7 phase sealing of valve plate device close to it；
Valve opening and closing detection device, the valve opening and closing detection device for detect valve plate device 7 it is in the closed position with
And open position.
The working principle of above-mentioned technical proposal are as follows: when fluid flows into Y shape runner 11, fluid forces valve plate device 7, so that
Valve plate device 7 is rotated upwards around the first connecting shaft 6 so that the Y shape runner 11 circulates, i.e., so that valve plate device 7 is in open position
It sets；When reverse fluid flow, valve plate device 7 is axial around the first connection under the action of self gravity and retrograde fluid pressures
Lower rotation is sealed valve seat 2, so as to avoid the reverse circulated of fluid, i.e., so that valve plate device 7 is in the closed position.
Above-mentioned technical proposal has the beneficial effect that above-mentioned technical proposal by setting valve opening and closing detection device to detect valve

The ratio of distance is greater than 1/2 less than 1.
Above-mentioned technical proposal has the beneficial effect that the setting of spool 32, pendant collet 33, sealing ring 34 has sealing effect good
The advantages of；Above-mentioned 7 structure of valve plate device is simple, and the first connecting shaft 6 arrives at a distance from the left end face of valve plate 72 (A in Fig. 1): the
(B in Fig. 1) ratio of distance of one connecting shaft 6 to 72 center line of valve plate is greater than 1/2 valve plate 72 can be made less than 1 reliably to rotate
Power is smaller when opening, and valve plate 72 can be made to fall sealing after rise.
In one embodiment, the valve opening and closing detection device includes:
Inductor 81, the inductor 81 are arranged on valve deck 3；
First connecting rod 82, the first connecting rod 82 are arranged on the rotating arm 71,82 bottom of first connecting rod
End is equipped with a steel ball 83 and is in contact with the rotating arm 71, and 82 top of first connecting rod extends through the spool 32 and valve
Lid 3, it is corresponding with 81 position of inductor that the first connecting rod 82 extends through 3 position of valve deck；
The top of the first connecting rod 82 is arranged in first hard magnetic body 84, first hard magnetic body 84；
The inductor 81 is also connected with external cable 85, is transferred to inductive signal by external cable 85 and remotely supervises
Control terminal, remote monitoring terminal can be computer.
The working principle of above-mentioned technical proposal are as follows: when fluid flows into Y shape runner 11, fluid forces valve plate 72, so that valve
Plate 72 and rotating arm connected to it 71 are around the first rotation upwards of connecting shaft 6, so that the Y shape runner 11 circulates, rotating arm 71
It withstands steel ball 83 and first connecting rod 82 is pushed to move upwards, be mounted on the first hard magnetic body 84 on first connecting rod 82 with
One connecting rod 82 moves upwards, and inductor 81 senses that 84 change in location of the first hard magnetic body generates inductive signal, the induction letter
Number remote monitoring terminal is transferred to by external cable 85；
When 11 inlet side fluid interruption of Y shape runner, valve plate 72 and rotating arm connected to it 71 are in self gravity and Y
It is rotated down under the action of 11 outlet side retrograde fluid pressures of shape runner around the first connecting shaft 6 and valve seat 2 is sealed, rotating arm
71 drive first connecting rods 82 and steel ball 83 move downward, and are mounted on the first hard magnetic body 84 on first connecting rod 82 with first
Connecting rod 82 moves downward, and inductor 81 senses that 84 change in location of the first hard magnetic body generates inductive signal, the inductive signal
Remote monitoring terminal is transferred to by external cable 85.
Above-mentioned technical proposal has the beneficial effect that above structure is simple, is in and unlatches and closes convenient for detection valve plate device 7
Position, and inductive signal is transferred to remote monitoring terminal by external cable 85 by inductor 81, convenient for long-range monitoring.
In one embodiment, the valve opening and closing detection device includes:
Second connecting rod 86,86 first end of the second connecting rod be connected in the first connecting shaft 6 and with the first connecting shaft
6 rotate synchronously, and 86 second end of the second connecting rod is extend out to outside valve body 1 after running through 1 side wall of valve body；
Round hard magnetic body mounting disc 87, the circle hard magnetic body mounting disc 87 are located at outside valve body 1, the circle hard magnetic body
Mounting disc 87 is fixedly connected with 86 second end of the second connecting rod；
Second hard magnetic body 88 and third hard magnetic body 89, second hard magnetic body 88 and third hard magnetic body 89 are fixedly mounted on institute
It states in round hard magnetic body mounting disc 87；
Mounting plate 810, the mounting plate 810 are arranged outside valve body 1, and are arranged between place's 1 outer wall of valve body with it and constitute
Installation cavity；
Position indicator 811, the position indicator 811 are mounted on the mounting plate 810, the position indicator
811 include induction part, and for the sensing part in the installation cavity, the induction part is equipped with the first instruction switch 8111 and the
Two instruction switches 8112；
When the valve plate device 7 is in the closed position, second hard magnetic body 88 is only corresponding with the first instruction switch 8111
