Model utility content
Thereby the purpose of this utility model is to provide the gas drive suction booster that a kind of low-pressure gas that can utilize large size piston end drives the highly pressurised liquid that produces small area piston end.
For achieving the above object, the technological scheme that the utility model adopts is: a kind of gas drive suction booster, comprise cylinder, left oil cylinder and right oil cylinder, left, right cylinder putter is connected with cylinder piston two sides respectively, two ends at cylinder are provided with a left side, right position limit switch, left, right position limit switch links with switch valve with two-position and five-pass respectively, the port of switch valve with two-position and five-pass is communicated with cylinder dual-side, pneumatic on-off valve is communicated with the another one port of two position switching valves, left, right oil cylinder is connected with band one-way valve quick release coupling one respectively, left, right oil cylinder is connected with band one-way valve quick release coupling two respectively, oil sump tank is connected with band one-way valve quick release coupling two, band one-way valve quick release coupling one is connected with oil passage control valve.
Preferably, described pneumatic on-off valve and the pipeline between switch valve with two-position and five-pass are provided with reduction valve.
Preferably, the pipeline between described oil sump tank and oil passage control valve is provided with filter.
Preferably, described filter is hydraulic pressure cartridge filter.
Preferably, described oil passage control valve is manual three position control valves.
The utility model adopts after said structure, thereby utilizes the low-pressure gas of large size piston end to drive the highly pressurised liquid that produces both sides small area piston end, and the constant pressure of output, and energy consumes minimum, has the high and feature that cost is low of output performance; Adopt gas-powered, without electric arc and spark, can use in hazardous location, very safe.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is schematic diagram of the present utility model.
In figure: 1 cylinder, 1a cylinder piston, 2 left oil cylinders, 3 right oil cylinders, 4 left and right position limit switches, 5 right position limit switches, 6 switch valve with two-position and five-pass, 7 pneumatic on-off valves, 8 oil sump tanks, 9 band one-way valve quick release couplings one, 10 band one-way valve quick release coupling two, 11 filters, 12 oil passage control valves, 13 reduction valve.
Embodiment
As shown in Figure 1, the utility model gas drive suction booster, comprise cylinder 1, left oil cylinder 2 and right oil cylinder 3, left, right oil cylinder 2, 3 push rods are connected with cylinder piston 1a two sides respectively, two ends at cylinder 1 are provided with a left side, right position limit switch 4, 5, left, right position limit switch 4, 5 link with switch valve with two-position and five-pass 6 respectively, the port of switch valve with two-position and five-pass 6 is communicated with cylinder 1 dual-side, pneumatic on-off valve 7 is communicated with the another one port of two position switching valves 6, left, right oil cylinder 2, 3 are connected with band one-way valve quick release coupling 1 respectively, left, right oil cylinder 2, 3 are connected with band one-way valve quick release coupling 2 10 respectively, oil sump tank 8 is connected with band one-way valve quick release coupling 2 10, band one-way valve quick release coupling 1 is connected with oil passage control valve 12.Described pneumatic on-off valve 7 and the pipeline between switch valve with two-position and five-pass 6 are provided with reduction valve 13.On the pipeline between oil sump tank 8 and oil passage control valve 12, be provided with filter 11.Above-mentioned filter 11 is hydraulic pressure cartridge filter.Oil passage control valve 12 is manual three position control valves.
Working principle, press enable switch valve 7, connect source of the gas, the contact that left position limit switch 4 is encountered the cylinder piston 1a left side starts, the left position work of switch valve with two-position and five-pass 6, gas enters into the left side cylinder body of cylinder 1, and the gas of cylinder 1 right side cylinder body is discharged, the small piston that cylinder piston 1a promotes left oil cylinder 2 and right oil cylinder 3 simultaneously moves right, and right oil cylinder 3 produces highly pressurised liquid; The highly pressurised liquid of right oil cylinder 3 exports oil passage control valve 12 to through pipeline and one 9 connections of band one-way valve quick release coupling; The liquid band one-way valve quick release coupling 2 10 of oil sump tank 8 sucks in left oil cylinder 2.When cylinder piston, 1a moves to low order end, right position limit switch 5 is encountered in the contact on the cylinder piston 1a right side, right lateral journey is switch activated, the right position work of switch valve with two-position and five-pass 6, gas enters into the right side cylinder body of cylinder 1, the gas of cylinder 1 left side cylinder body is discharged through two position switching valves 6, and the small piston that cylinder piston 1a promotes left oil cylinder 2 and right oil cylinder 3 is moved to the left, and left oil cylinder 2 produces highly pressurised liquid; The highly pressurised liquid of left oil cylinder 2 is connected output liquid to oil passage control valve 12 through pipeline and band one-way valve quick release coupling 1; The liquid band one-way valve quick release coupling 2 10 of oil sump tank 8 sucks in right oil cylinder.So be cycled to repeat above-mentioned action, thereby realize, utilize the low-pressure gas of large size piston end to drive the highly pressurised liquid that produces both sides small area piston end to drive frock clamping etc.By oil circuit control control valve 12 oil circuit controls, controlling frock clamping moves.
