For mandrel perpendicular to the upper and lower end of the valve body, the upper and lower inwall of the valve body is pressed close in the upper and lower end of the valve plate, described
The left and right end of valve plate has been fixedly connected with reinforcement plate and backboard, forms Y-shaped between the reinforcement plate, backboard and valve plate, institute
The surface area for stating reinforcement plate is less than the surface area of the backboard, and the reinforcement plate and backboard of the left and right end of the valve plate are with described
Central shaft is that axis forms Central Symmetry.
Further, breach is formed between the upper and lower end of the reinforcement plate and the inwall of the valve body, current can be from institute
State breach and flow to the backboard.
Further, the inwall of the valve body is pressed close in the upper and lower end of the backboard.
Further, the pulsation rate adjustable plate of arc is additionally provided with left and right sides of the valve interior wall, the pulsation rate is adjusted
The camber line of section plate rotates inswept track with the reinforcement plate and backboard and matched.
Further, the angle between the reinforcement plate and the backboard is 60~90 degree.
Compared to the prior art the utility model, has the following advantages that and beneficial effect：The utility model is in valve plate end
Reinforcement plate increase lifting surface area is set, promotes valve plate rotation using the flowing of water, the pulse for realizing water springs up, instead of existing
The compressed-air system of device；In addition, the utility model is simple in construction, without energy resource supply, manufacture and production cost are greatly reduced,
Improve production efficiency.

Embodiment
As shown in Figure 1 to Figure 3, a kind of mechanical pulse valve, including valve body 1, the valve body 1 are provided with the water inlet to communicate with one another
Mouth 11 and delivery port 12, the valve body 1 is interior to be provided with the valve plate 2 that can be rotated around central shaft 13, and the central shaft 13 is perpendicular to institute
The upper and lower end of valve body 1 is stated, the upper and lower inwall of the valve body 1 is pressed close in the upper and lower end of the valve plate 2, the valve plate 2
Left and right end has been fixedly connected with reinforcement plate 3 and backboard 4, forms Y-shaped between the reinforcement plate 3, backboard 4 and valve plate 2, institute
The surface area for stating reinforcement plate 3 is less than the surface area of the backboard 4, the reinforcement plate 3 and backboard 4 of the left and right end of the valve plate 2 with
The central shaft 13 is that axis forms Central Symmetry.
In the present embodiment, the section of valve body is circle, or square or other shapes.The reinforcement plate 3 it is upper and lower
Breach is formed between the inwall of end and the valve body 1, current can flow to the backboard 4 from the breach.The backboard 4
The inwall of the valve body 1 is pressed close in upper and lower end, when the valve plate 2 is vertical with the inwall of valve body 1 or so, backboard 4 and valve body
1 is internally formed sealing to stop that current pass through.Such as Fig. 3, the reinforcement plate 3 and the non-axis symmetry of backboard 4 of the left and right sides of valve plate 2
But center symmetric setting, i.e., along water (flow) direction, always reinforcement plate 3 and backboard 4 are by water jet propulsion on right side, and left side only has backboard
4 are contacted with current, and the reinforcement plate in left side is blocked in before backboard, and then stress surface is always larger than left side on the right side of valve plate, and then pushes away
Dynamic valve plate rotates in the counterclockwise direction.Angle between the reinforcement plate 3 and the backboard 4 is 60~90 degree.
As shown in Figure 4 and Figure 5, the pulsation rate adjustable plate 5 of arc is additionally provided with left and right sides of the inwall of valve body 1, it is described
The camber line of pulsation rate adjustable plate 5 rotates inswept track with the reinforcement plate 3 and backboard 4 and matched.When reinforcement plate 3 and backboard 4
When in the range of the pulsation rate adjustable plate 5, valve body 1 forms closed, and now almost no current can pass through valve body.Such as
Fruit is not provided with pulsation rate adjustable plate 5, during the valve plate 2 rotates, necessarily has current and is flowed through between gap.Such as Fig. 6
It is shown, show water flow oscillogram when pulse regulation plate and no pulse adjustable plate.The arc length of pulse regulation plate is adjusted,
Pulsation rate can be changed.Pulsation rate is the ratio of shut-in time and opening time, i.e. a/b, wherein parameter a and pulse regulation plate
Arc length positive correlation.
Described above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of the utility model technical principle is not departed from, some improvement and modification can also be made, these change
Enter and also should be regarded as the scope of protection of the utility model with modification.
