With reference to Fig. 1, in this embodiment, constant voltage air-supporting slide rail system of the present utility model comprises pressurized air control gas circuit 20 and two air-float guide rails 50.Pressurized air control gas circuit 20 can be simultaneously two air-float guide rail 50 air feed up and down, the structural parameter of these two air-float guide rails are identical.Particularly, pressurized air is controlled gas circuit 20 and is used for responding to the gas pressure in air-float guide rail 50, and when gas pressure is less than preset pressure value, to the interior make-up gas of air-float guide rail 50, thereby guarantees that the gas pressure in air-float guide rail 50 keeps constant.
In one embodiment, this pressurized air control gas circuit 20 comprises a solenoid valve 25, a constant-pressure gas storage tank 26 and a pressure switch 30.Solenoid valve 25 and pressure switch 30 are electrically connected to.When the gas pressure in air-float guide rail 50 is less than preset pressure value, pressure switch 30 is opened and solenoid valve 25 is synchronously opened.When the gas pressure in air-float guide rail 50 reaches preset pressure value, pressure switch 30 disconnects and solenoid valve 25 close synchronouslies.Preferably, pressurized air control gas circuit 20 also comprises filter 23 and precise pressure regulating valve 24.Filter 23 filters the pressurized air of sending in pressurized air control gas circuit 20, and precise pressure regulating valve 24 is arranged between filter 23 and solenoid valve 25, for regulating the compressed-air actuated air pressure after filtration.Thus, filter 23, precise pressure regulating valve 24, solenoid valve 25, constant-pressure gas storage tank 26 and pressure switch 30 are connected successively and are led in air-float guide rail 50 by sealing pipeline, thereby pressurized air also can input in air-float guide rail 50 by filter 23, precise pressure regulating valve 24, solenoid valve 25, constant-pressure gas storage pipe 26 and pressure switch 30 successively.In this embodiment, by the line branching after pressure switch 30, lead in two air-float guide rails 50 simultaneously.According to the pneumatic parameter in air-float guide rail, set demand, constant-pressure gas storage tank 26 also can be selected different constant voltage values.When the force value in air-float guide rail 50 is less than predetermined value, pressure switch 30 is opened rapidly, the pressure that gas in constant-pressure gas storage tank 26 can be responded to rapidly in air-float guide rail gas circuit is less than predetermined value, thereby to gas circuit make-up gas, therefore can overcome in prior art and reflect slow defect by compressed gas source make-up gas, guarantee to remain constant voltage in air-float guide rail.
In one embodiment, this pressurized air control gas circuit 20 also comprises a flow control valve 27.Flow control valve 27 is arranged between constant-pressure gas storage tank 26 and pressure switch 30, and when pressure switch 30 and solenoid valve 25 unlatching, flow control valve 27 regulates to the supplementary gas flow of the gas circuit of air-float guide rail.
