Pressue device use principle：The high-order low pressure water source of great rivers enters water inlet pipe 3, reaches adding installed in low level Pressure device 1, into the cavity 101 of multiple pressue devices 1 in parallel, when the water of cavity 101 completely after current along the straight line of valve shaft 1 Go out upwards, flow rate of water flow is increasing and impacts shock plate 115, when upward impulsive force is more than shock plate, valve shaft and valve During the gravity of plate, for the valve plate one of valve one in the case where shock plate drives valve shaft one, valve plate one is rapidly moving upward and closes Valve one, now due to inertia, water inlet liquid in pipe continues to keep original high-speed motion state to make generation in cavity 101 very high Fluid pressure, when fluid pressure be more than valve two spring pressure when, push valve two open, liquid at high speed is gone out, into high pressure Outlet pipe, after liquid at high speed is gone out, rapid pressure drop in cavity 1, spring promotes the valve plate two of valve two to enter valve two Row is closed, and high-pressure outlet, valve plate one does not stress, due to its building block（Valve shaft one and shock plate）Action of Gravity Field, decline Valve one is opened, liquid impacts shock plate again by valve shaft one again, and valve plate one rises closing valve one again, and uphill process is not Disconnected to repeat, liquid constantly enters high-pressure intake pipe, the effect of accumulator be when water rushes the high speed of valve two and gone out, can not in cavity Water is transported away in time, there is air inside accumulator, air has compressibility, so valve two open be some water immediately Into in accumulator, when valve two is closed, because the pressure inside accumulator is more than the pressure in cavity, the water entered is again Flow into cavity into high-pressure intake pipe.

When the water of above-mentioned pressue device outflow enters valve manifold, valve manifold is connected to the valve five and valve of two linkages Six, now plunger be in the leftmost position of plunger case, valve six is closed, and valve eight is opened, and valve five is opened, and valve seven closes Close, valve four is closed, and then water enters valve pocket five from valve five, and valve pocket five connects plunger case left end water inlet, so as to promote post Plunger moves from the left side to the right in plug cylinder, while is displaced outwardly together with piston, after piston is displaced outwardly, in suction pump Vacuum increases, and the inside air pressure is less than outside atmosphere pressure, and therefore, atmospheric pressure promotes water to enter from the water inlet end for the chamber that draws water, and promotes Valve three is opened, and water enters intracavitary of drawing water, and now, the piston on right side moves right, and is promoted the water of the intracavitary of drawing water on right side, is worked as liquid When body pressure is more than surface pressure outside outlet pipe, the valve four on right side is opened, and the valve three on right side is closed under the action of the spring, and water is high Speed enters outlet pipe, and the repetition that plunger moves back and forth the suction pump for realizing both sides is drawn water pressure water, and plunger connects much larger than plunger Push rod.

Above-mentioned plunger drives during moving back and forth, and drives power rail to move back and forth, during power rail moves right, band Shake bar to rotate around fixed pin joint 3 222, rocking bar drives L-type pull bar 219 to be moved to the left after rotating, and L-type pull bar is another End pulls spacing push pedal to realize that pull bar is moved to the left, and promotes valve plate eight to close, and valve plate seven is opened, and valve plate seven drives the first L-type Rocking bar 213 rotates around fixed pin joint 1, under being rotated down of the upper end of the first L-type rocking bar 213, drives valve plate five to close Valve five, valve plate eight drive the second L-type rocking bar 214 to be rotated around fixed pin joint 2 217, the upper end of the second L-type rocking bar 214 to Under upper rotation, valve plate six is opened, and water enters the water inlet of plunger case right-hand member from valve pocket six, real so as to promote plunger to be moved to the left Existing plunger case left end water enters in valve pocket five, is overflowed at valve seven, and moving back and forth for plunger drives link gear to realize valve Five and valve six, the one of valve seven and valve eight open a conjunction.

The V-type limited block set on the downside of above-mentioned pull bar, pull bar is moved to the left, when roller crosses V-type limited block top, In the expansion baffle rod that roller connects under the action of the spring, the stress of roller is upward, and it contacts the stress at V-type limited block right side Vertically and right side, according to by force resolution, a thrust to the left is produced to pull bar, promotes pull bar is quickly mobile to realize The opening of valve seven and the closing of valve eight, move right similarly, so as to improve the sensitivity of valve seven and valve eight and close Seal reliability.

The above-mentioned water that is pumped into of drawing water can be the water overflowed at pressue device or linkage valve, or downstream status Water.

The advantages of above-mentioned suction pump, is as follows：

1）High-order water potential energy impacts pressue device, the outflow of part water, and part water enters plunger case, and plunger case promotes suction pump to carry out Draw water, by the use of water potential energy as power source, avoid using electric energy, more save the energy, obtained by using the water level of big potential energy The high-order water of small potential energy, obtain it is high-lift draw water, using water as power source, do not pollute, cost is lower, more environmentally-friendly, Waterpower utilization rate greatly improves；

2）Closed using shock plate band movable valve one, and impact the valve plate two with spring and open valve pocket two, current are automatically under Position waterpipe, pressure are reduced, resetted under the action of the spring, are closed valve one at valve pocket one and shock plate and are opened, water is realized in circulation Pressurization, outflow part water flow into cistern, cistern can as the water source that draws water of suction pump, realize recycling, pass through Pressurization back and forth, high-lift water level is obtained, it is bigger using multiple pressue device parallel ways, the hydraulic pressure of acquisition；

3）By moving back and forth for plunger case inner plunger, in the presence of pressue device water under high pressure, the power of push rod is more preferable, two-way Suction pump is set, and plunger case utilization rate greatly improves, and efficiency of drawing water is double；

4）A conjunction is opened by the one of suction pump water inlet and delivery port, quickly realizes high-lift draw water；

5）Using the valve five and valve six of linkage, linkage effect can be effectively controlled in the presence of plunger case, control is more Add simple and convenient；

6）Link gear uses to be formed with gangbar more, and simple in construction, cost is low, and control is accurate reliable；

7）Pull bar bottom is provided with limited block, the valve opening of valve five and the upper side wall of valve six can be opened or closed more Closely, realize that linkage action is more accurate.
