The opening and closing of door three and valve four, drawn water and draining so as to realize.
Preferably, above-mentioned valve 1 includes valve plate 1 and valve pocket 1, and the upper surface of valve plate 1 is connected with valve
Axle 1, valve shaft 1 are connected to shock plate 115 after passing through valve pocket 1, and valve pocket 1 is vertically set on the side of cavity 101
On wall, valve shaft 1 is axially displaceably connected to impact board mount 104 and valve plate 1 can be moved into rear enclosed valve pocket one
111 is inner, and impact board mount 104 is fixedly connected in the valve pocket 1 of the extraneous valve pocket 1 of connection, valve plate 1 just under
The supporting table of valve plate one is provided with the valve pocket 1 of side, the valve shaft connected by water impact shock plate and valve plate 1
One and the Action of Gravity Field of shock plate, the quick washing shock plate and impact sheet reset of current are realized, so as to realize the pressurization of current
And spilling, the water of spilling can be as the water sources that are pumped into of drawing water.
Use principle：Water with certain high potential energy enters pressue device 1 from water inlet pipe 3, now due to valve plate one
110th, valve shaft 1, the gravity of shock plate 115, valve plate 1 and valve pocket 1 are in open position, when pressurization fills
Put 1 li of water to fill rapidly and go out along valve shaft 1 and impact shock plate 115, when the impulsive force of water is more than valve plate one
110th, during the joint weight of valve shaft 1, shock plate 115, valve plate 1, valve shaft 1, shock plate 115 are lifted rapidly upward
Rise, valve plate 1 and valve pocket 1 are closed rapidly, because fluid pressure increases moment rising suddenly in inertia pressue device, are pushed away
The quick motion simultaneously from left to right of big piston 103, piston rod 106, piston 201 is moved, as big piston 103 moves right, is resetted
Spring 107 is compressed, and support bar 108 is also pressurized and moved right simultaneously, due to return piston 109 and the phase of support bar 108
Even, so also move right simultaneously, because return piston 109 moves right, so the vacuum on the left side increases, it is big in pressurizing chamber
Air pressure is more than the inside atmospheric pressure, so valve plate 2 117 overcomes the elastic force of back-moving spring 2 125 and opens water and enter return piston chamber
Interior, until return piston 109, which is pressed onto, allows position, valve plate 2 117 is closed, while the valve of one group of identical function on its opposite
Running is identical, ensures that big piston movement is steady, at the same time piston 201 travels forward leading space by compressed liquid pressure
Strong increase, valve plate 4 209 overcome the elastic force of back-moving spring 4 214 and open highly pressurised liquid and go out rapidly.When big piston 103 is in
Compression spring 137 is resetted during Far Left it is in and be stretched state, due to resets the right-hand member of compression spring 137 and movable cage plate 138, solid
Determining support base 139, the two are fixedly linked and are connected due to resetting the left end of compression spring 137 with the right-hand member of postive stop baffle 1, limit
Position baffle plate 1 be fixed on piston rod 106, so in the presence of the pulling force of compression spring 137 is resetted interior pressure release valve plate 131 and
Pressure release valve plate 128 is closed, while pressure release valve plate 128 and pressure release valve pocket 129 are closed, therefore in big piston 103 by fluid pressure
Shi Gongtong is moved from left to right, and the pressure inside cavity 101 is moved right with big piston 103 and is declined, it is to big piston 103
Pressure be less than back-moving spring 107 and with 107 corresponding tension force of spring of back-moving spring.Then big piston 103 is to left movement, by
It is connected in big 103 and return piston 109, return piston 109 is also simultaneously to left movement, and now valve plate 2 117 is to close,
And valve plate 5 121 overcomes the tension force opening water of back-moving spring 5 126 to spray immediately, but valve plate 5 121 does not have valve plate two here
The valve aperture of 117 sealings is big, therefore the water speed that water enters from 121 water sprayed not at valve plate 2 117 is big, so that
The speed that big piston 103 does not move right to the speed of left movement is big, just because of so, when big piston 103 is to left movement,
Reset compression spring 137 and act on the power of postive stop baffle 1 to the left rapidly, the coupled piston bar 106 and by interior relief valve of upspringing
Plate 131 is opened, because now fluid pressure is less than the elastic force that postive stop baffle 1 acts on, while pressure release valve plate 128 is also opened,
Liquid pressure in cavity 101 declines rapidly, big piston 103 return, and due to resetting the nature of compression spring 137 quickly
The left side perpendicular of lower left side perpendicular and back-moving spring 107 is not at grade, and the left side of back-moving spring 107
Perpendicular has a small distance than resetting compression spring 137 in Far Left, so when big piston 103 returns to original position, it is multiple
Position compression spring 137 is in the state being stretched.Pressure release valve plate 131 and pressure release valve plate 128 be closed in simultaneously, pressure release valve plate 128
Closed with pressure release valve pocket 129, the fluid pressure in cavity 101 reduces at the same time, valve plate 1, valve shaft 1, shock plate
115 are reopened under gravity, and water impacts shock plate 115 again, and above procedure constantly repeats, and water is just pressed than entering
The eminence of high more than 20 times of water pipe 3.
The advantages of above-mentioned suction pump：
1）The present invention impacts pressue device by high-order water potential energy, and part water flows out at shock plate, after closing valve one, promotes
Big piston moves right, and big piston promotes suction pump draw water, and by the use of water potential energy as power source, avoids using electric energy,
More save the energy, the high-order water of small potential energy obtained by using the water level of big potential energy, obtain it is high-lift draw water, made using water
For power source, not polluting, cost is lower, more environmentally-friendly, and waterpower utilization rate greatly improves, of the invention due to not electricity consumption, so
There is no the appliance materials such as field coil, stator coil, magnetic links, due to without oil, so a cutting system without internal combustion engine,
There is no the transmission mechanisms such as gear-bearing, therefore cost is especially low and does not have to oily not electricity consumption；
2）The present invention is closed using shock plate band movable valve one, and impacts big piston, and big piston driving piston adds to water pump
Gas Pressure water discharging, and in the presence of big piston reset spring, drawing water for suction pump is completed, big piston moves back and forth, and circulation is real
The pressurization of existing water, outflow part water flow into cistern, and cistern can be realized and recycle as the water source that draws water of suction pump,
By pressurization back and forth, high-lift water level is obtained；
3）By setting pressure relief valve, when big piston is moved to the left under action of reset spring, back-moving spring is in return piston
In the presence of, be slowly moved to the left, and the reset compression spring snap action at middle part is to pressure relief valve, pressure relief valve can pair plus
High-order water can carry out pressure release in pressure device, and while sluiced at shock plate under effect, can realize the Rapid reset of piston,
So as to realize that the quick of suction pump is drawn water；
