Pressurizing device uses principle: the high-order low pressure water source of great rivers enters water inlet pipe 3, reaches and is mounted on adding for low level
Pressure device 1, into the cavity 101 of the pressurizing device 1 of multiple parallel connections, water flow is along one 114 straight line of valve shaft after 101 water of cavity is full
It goes out upwards, flow rate of water flow is increasing and impacts shock plate 115, when upward impact force is greater than shock plate, valve shaft and valve
When 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, at this time due to inertia, liquid in pipe of intaking continues to keep original high-speed motion state to keep generation in cavity 101 very high
Fluid pressure, when fluid pressure be greater 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 push valve two valve plate two to valve two into
Row is closed, and high-pressure outlet, valve plate one does not stress, due to the gravity of its building block (valve shaft one and shock plate), decline
Valve one is opened, liquid passes through valve shaft one again and impacts shock plate 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 two high speed of valve and goes out, cannot in cavity
Water is transported away in time, there is air inside accumulator, air has compressibility, so valve two opening be some water immediately
Into in accumulator, when valve two is closed, since the pressure inside accumulator is greater than the intracorporal pressure of chamber, the water entered is again
It flows into cavity and is entering high-pressure intake pipe.
When the water of above-mentioned pressurizing device outflow enters valve manifold, valve manifold is connected to the valve five and valve of two linkages
Six, plunger is in the leftmost position of plunger case at this time, and valve six is closed, and valve eight is opened, and valve five is opened, and valve seven closes
It closes, valve four is closed, and then water enters valve chamber five from valve five, and valve chamber five is connected to plunger case left end water inlet, to push column
Plunger is mobile from the left side to the right in plug cylinder, while being displaced outwardly together with piston, after piston is displaced outwardly, in suction pump
Vacuum degree increases, and the inside air pressure is less than outside atmosphere pressure, and therefore, atmospheric pressure pushes water to enter from the water inlet end for the chamber that draws water, and pushes
Valve three is opened, and water is intracavitary into drawing water, at this point, the piston on right side moves right, is pushed the intracavitary water that draws water on right side, is worked as liquid
When body pressure is greater 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 of realization two sides, which is drawn water, presses water, and plunger is much larger than plunger connection
Push rod.
Above-mentioned plunger drives during moving back and forth, and power rail is driven to move back and forth, during power rail moves right, band
Shake bar to rotate around fixed hinge point 3 222, drives L-type push-pull rod 219 to be moved to the left after rocking bar rotation, L-type push-pull rod is another
End pulls limit push plate to realize that push-pull rod is moved to the left, and valve plate eight is pushed to be closed, and valve plate seven is opened, and valve plate seven drives the first L-type
Rocking bar 213 is rotated around fixed hinge point 1, under being rotated down of 213 upper end of the first L-type rocking bar, valve plate five is driven to be closed
Valve five, valve plate eight drive the second L-type rocking bar 214 to rotate around fixed hinge point 2 217, the second L-type rocking bar 214 upper end to
Under upper rotation, valve plate six is opened, and water enters the water inlet of plunger case right end from valve chamber six, so that plunger is pushed to be moved to the left, it is real
Existing plunger case left end water enters in valve chamber five, overflows from valve seven, and moving back and forth for plunger drives linkage mechanism to realize valve
Five and valve six, valve seven and valve 8 one open a conjunction.
The V-type limited block being arranged on the downside of above-mentioned push-pull rod, push-pull rod is moved to the left, when idler wheel crosses V-type limited block top,
Idler wheel connection expansion baffle rod under the action of the spring, the stress of idler wheel is upward, contact V-type limited block right side at stress
Vertically one thrust to the left is generated to push-pull rod, push-pull rod is promoted to fast move realization according to by force resolution with right side
The opening of valve seven and the closing of valve eight, move right similarly, to improve the sensitivity of valve seven and valve eight and close
Seal reliability.
The above-mentioned water being pumped into that draws water can be the water overflowed at pressurizing device or linkage valve, can also be downstream status
Water.
The advantages of above-mentioned suction pump, is as follows:
1) high-order water potential energy impacts pressurizing device, the outflow of part water, and part water enters plunger case, and plunger case pushes suction pump
It draws water, using water potential energy as power source, avoids using electric energy, more the saving energy, by using the water level of big potential energy
The high-order water for obtaining small potential energy, obtains drawing water for high lift, using water as power source, does not pollute, and cost is lower, more ring
It protects, waterpower utilization rate greatly improves；
2) closed using shock plate band movable valve one, and impact valve plate two with spring and open valve chamber two, water flow automatically into
Enter the next waterpipe, pressure reduction resets under the action of the spring, is closed valve one at valve chamber one and shock plate and opens, circulation is real
The pressurization of existing water, outflow part water flow into reservoir, and reservoir can be realized and be recycled as the water source that draws water of suction pump,
By pressurization back and forth, the water level of high lift is obtained, using multiple pressurizing device parallel ways, the hydraulic pressure of acquisition is bigger；
3) moving back and forth by plunger case inner plunger, under the action of pressurizing device high pressure water, the power of push rod is more preferable,
Two-way setting suction pump, plunger case utilization rate greatly improve, and efficiency of drawing water is double；
4) conjunction is opened by the one of suction pump inlet and outlet, fast implements drawing water for high lift；
5) using the valve five and valve six of linkage, linkage effect can be effectively controlled under the action of plunger case, controlled
Make simpler convenience；
6) for linkage mechanism using mostly forming with interlocking bar, structure is simple, and at low cost, control is accurate reliable；
7) push-pull rod bottom is provided with limited block, the valve opening of six upper side wall of valve five and valve can be opened or closed
It is even closer, realize that linkage action is more accurate.
