Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
Hydraulic pressure schematic diagram of the present invention as shown in Figure 1, the present invention mainly is made up of with 400 4 modules of moisturizing exhaust module water supply module 100, control valve group 200, synchronous hydraulic cylinder group 300, water supply module 100 is responsible for supplying water to whole system, work by control valve group 200 different solenoid valves realizes flow direction-changing, thereby drive polyphone synchronous hydraulic cylinder group 300, finish the lifting action of hydraulic cylinder piston rod, intermediate connection pipeline by 400 pairs of synchronous hydraulic cylinders of moisturizing exhaust module group 300 after one period operating time carries out the moisturizing exhaust, guarantees the synchronism of two hydraulic cylinders.
As shown in Figure 1 and Figure 2; water supply module 100 drives three plunger high-pressure water pumps 105 by motor 104 and supplies water from water tank 103 to the water supply line 108 of system; by pressure gauge 102 display system working pressures; accumulator 101 is realized the function of steady system damping noise reduction; be communicated to the water cycle of water return pipeline 109 pumping plant when guaranteeing that water pump is treated work by bypass solenoid valve 107; be communicated to water return pipeline 109 by stainless steel relief valve 106; can when system works, make the water of overvoltage be back to water tank 103, protection equipment.
As Fig. 1, shown in Figure 4, control valve group 200 is connected to form by four two-position two-way solenoid valves and two one-way valves, realizes the three-position four-way valve function.The water intake 205 of control valve group 200 is connected in water supply line 108, pass through tee union, one the road shunts to first solenoid valve 203 that is connected in series and first one-way valve 202, the outlet 201 on this road is communicated in the rodless cavity of the big hydraulic cylinder 301 of synchronous hydraulic cylinder group 300, is communicated with backwater outlet 206 by the 3rd solenoid valve 207 simultaneously; Shunt to second solenoid valve 208 that is connected in series and second one-way valve 209 on another road, and the outlet 210 on this road is communicated in the rod chamber of the little hydraulic cylinder 302 of synchronous hydraulic cylinder group 300, is communicated with backwater outlet 206 by the 4th solenoid valve 204 simultaneously.Because the pressure electromagnetic valve does not have the reversible lock function, when the solenoid valve dead electricity was in closed condition, high pressure water can't pass through solenoid valve from the solenoid valve water intake, but the water of waterexit end just can oppositely pass through solenoid valve under tap water pressure; Therefore need increase one-way valve at the water outlet end of first solenoid valve 203 and second solenoid valve 208,, realize the bidirectional locking function of solenoid valve with this to prevent the high pressure water adverse current.
As Fig. 1, shown in Figure 3, synchronous hydraulic cylinder group 300 is composed in series by intermediate connection pipeline 304 by the rodless cavity inlet 308 of the rod chamber of big hydraulic cylinder 301 inlet 303 and little hydraulic cylinder 302; The rodless cavity inlet 309 of big hydraulic cylinder 301 is communicated with the outlet 201 of control valve group 200, and the rod chamber of little hydraulic cylinder 302 enters the mouth and 307 is communicated with the outlet 210 of control valve group 200.Intermediate connection pipeline 304 is provided with gas exhaust piping 305, links to each other with the exhaust joint 402 of moisturizing exhaust module 400, also is provided with water pipe 306 simultaneously on intermediate connection pipeline 304, links to each other with the moisturizing ball valve 401 of moisturizing exhaust module 400.Two hydraulic cylinders are vertically installed by hydraulic cylinder support 310, and its basic structure is identical, Figure 5 shows that the structure of big hydraulic cylinder 301: piston rod 313 upper ends are installed and are hung 311, and the other end installation piston 315 can be in stainless steel cylinder body 314 reciprocates inside; Cylinder body 314 upper ends are equipped with guide sleeve 312, play sealing and piston rod guiding; Cylinder body 314 tops are provided with rod chamber inlet 303, and the lower end is provided with rodless cavity inlet 309.
The effective work area of rod chamber that two hydraulic cylinder synchronization principles are big hydraulic cylinders 301 equates to realize with the effective work area of the rodless cavity of little hydraulic cylinder 302, specifically, the piston area of big hydraulic cylinder 301 is S1, the piston rod area is S2, the piston area of little hydraulic cylinder 302 is S3, then S3=S1-S2.Certainly, also can utilize above-mentioned principle to be in series for a plurality of hydraulic cylinders, the rod chamber of previous hydraulic cylinder is connected by intermediate duct with the rodless cavity of a back hydraulic cylinder, and the effective work area of the rod chamber of previous hydraulic cylinder equals the effective work area of rodless cavity of a back hydraulic cylinder.
During real work, motor 104 drives three plunger high-pressure water pumps, 105 water supply starts, and when control valve group 200 was not worked, current circulated at the pipeline mesolow by bypass solenoid valve 107; In case control valve group 200 is started working, bypass solenoid valve 107 dead electricity closures then, build-up pressure in the pipeline.When needs synchronous hydraulic cylinder group 300 carries out rising the cylinder action, control circuit makes first solenoid valve 203 and the 4th solenoid valve 207 get electric work, the water of water intake 205 arrives the inlet end of first solenoid valve 203 and second solenoid valve 208, since second solenoid valve 208 not electric water route is obstructed, high pressure water is by first solenoid valve 203 and first one-way valve 202, enter the rodless cavity inlet 309 of big hydraulic cylinder 301 through outlet 201, the piston 315 of big hydraulic cylinder 301 moves upward, its rod chamber 303 backwater that enter the mouth arrive the rodless cavity inlet 308 of little hydraulic cylinder 302 by intermediate connection pipeline 304, the piston of little hydraulic cylinder 302 moves upward simultaneously, its rod chamber 307 backwater that enter the mouth arrive pipeline 210, because second solenoid valve, 208 water outlet ends are provided with second one-way valve 209, water from then on road passes through, discharge and can only arrive backwater outlet 206, realized that by this process the big hydraulic cylinder 301 and the piston of little hydraulic cylinder 302 rise synchronously by the 4th solenoid valve 207.The cylinder that in like manner contracts action is must electric work by second solenoid valve 208 and the 3rd solenoid valve 204, and other solenoid valve dead electricity are closed and realized.
More than describing is explanation of the invention, is not that institute of the present invention restricted portion is referring to claim to the qualification of invention, and under the situation of spirit of the present invention, the present invention can do any type of modification.
