Pressue device use principle：The high-order low pressure water source of great rivers enters water inlet pipe 3, reaches adding mounted on low level Pressure device 1, into the cavity 101 of the pressue device 1 of multiple parallel connections, 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 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, at this time 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 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 its building block（Valve shaft one and shock plate）Gravity, 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 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 more than the pressure in cavity, the water entered is again It flows 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, at this time 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 It closes, valve four is closed, and then water enters valve chamber five from valve five, and valve chamber five connects plunger case left end water inlet, so as to push column Plunger is moved from the left side to the right, while is displaced outwardly together with piston in plug cylinder, 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 enters intracavitary of drawing water, at this point, the piston on right side moves right, is pushed 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 enter outlet pipe, plunger move back and forth realize both sides suction pump repetition draw water pressure water, plunger 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 joint 3 222, L-type push-pull rod 219 is driven to be moved to the left after rocking bar rotation, L-type push-pull rod is another End pulls limiting 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 joint 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 be rotated around fixed hinge joint 2 217,214 upper end of the second L-type rocking bar to Under upper rotation, valve plate six is opened, and water enters the water inlet of plunger case right end from valve chamber six, real so as to which plunger be pushed to be moved to the left Existing plunger case left end water enters in valve chamber five, is overflowed at 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 set 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, In the expansion baffle rod that idler wheel connects under the action of the spring, the stress of idler wheel is upward, the stress at contact V-type limited block right side Vertically and right side, according to by force resolution, a thrust to the left is generated to push-pull rod, promotes push-pull rod 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 being pumped into that draws water can be the water or downstream status overflowed at pressue device or linkage valve Water.
