Description
Technical field:
The utility model relates to the three-way valve in a kind of pneumatic actuator system.
Background technique:
Conventional pneumatic actuator system comprises all that generally source of the gas, three-way valve, cylinder and some can guarantee the auxiliary element of pneumatic actuator system proper functioning etc.; Described three-way valve comprises handle, spool, valve body and is arranged in body cavity and is used for the vent plug of sealed valve body lower seal air chamber; Described vent plug bottom is connected with spring; Described handle is connected the spool top; Described spool is arranged in body cavity and slidably is connected with valve body; Described valve body is provided with the gas-entered passageway that is connected with source of the gas and the outlet passageway I that is connected with cylinder and outlet passageway II; Described gas-entered passageway communicates with sealed air chamber.When user's rotatable handle moves down spool, the spool bottom can be pushed vent plug open, at this moment, sealed air chamber is opened, gas begins to flow in outlet passageway I and the outlet passageway II through gas-entered passageway and sealed air chamber, finally flow into cylinder through outlet passageway I and outlet passageway II, cylinder is started working; And when user's opposite spin handle, spool moves up, and vent plug is sealed sealed air chamber under the effect of spring force, and at this moment, cylinder quits work.Though the prior art three-way valve is extensively adopted by pneumatic actuator system institute because of simple in structure, but, still there is a deficiency in it in actual application: when when user's opposite spin handle spool being moved up, vent plug can be closed sealed air chamber in effect following moment of spring force, at this moment, gas with certain pressure will remain in the cylinder, thereby cause cylinder when not working, still will bear the expansive force of a gas, in the course of time, can shorten greatly the actual life of cylinder.
The model utility content:
The technical problems to be solved in the utility model is, provide a kind of can be in time gaseous emission in the cylinder when not in running order fall, thereby can improve the cylinder three-way valve in working life greatly.
Technical solution of the present utility model is, a kind of three-way valve with following structure is provided, and it comprises valve body, is arranged in the spool of body cavity, is connected the handle at spool top and is arranged in body cavity and be used for the vent plug of sealed valve body lower seal air chamber; Spring I is arranged at described vent plug bottom; Described valve body top is provided with cavity; Described valve body lower portion is provided with outlet passageway I and the outlet passageway II that is used for the gas-entered passageway that is connected with source of the gas and is used for being connected with cylinder; Described spool is provided with the exhaust passage; Bottom, described exhaust passage communicates with outlet passageway I and outlet passageway II, and its top communicates with cavity; Described body wall is provided with the relief opening that communicates with cavity.
After adopting above structure, compared with prior art, the utlity model has following advantage: because the utility model is provided with the exhaust passage on spool, and the bottom of exhaust passage communicates with outlet passageway I and outlet passageway II, and the top communicates with relief opening on the body wall, therefore, when the spool in the utility model moves down, bottom, described exhaust passage can be close on the vent plug, and at this moment, the exhaust passage is inoperative; And when user's opposite spin handle, be that spool is when moving up, bottom, described exhaust passage can break away from vent plug and communicate with outlet passageway I and outlet passageway II rapidly, at this moment, gas in the cylinder will flow into the exhaust passage and discharge through relief opening, gas in the cylinder all emits the most at last, just because of the gas in the cylinder of the utility model after work can being finished is discharged rapidly, therefore, the utility model has effectively avoided gas to stockpile in cylinder, thus the working life of having improved cylinder greatly.

Embodiment:
The utility model is described in further detail below in conjunction with the drawings and specific embodiments:
As Fig. 1, Fig. 2 and shown in Figure 3, in this embodiment, the utility model three-way valve comprises handle 2, spool 3, cover plate 1, sealing gasket 4 and valve body 6; Described handle 2 is connected spool 3 tops by screw; Described spool 3 bottoms are arranged in valve body 6 inner chambers, and slidably are connected with valve body 6; Be connected with " O " shape seal ring between described spool 3 and the valve body 6; Be connected with straight pin 18 and spring II17 on the described spool 3; Described spring II17 two ends withstand between straight pin 18 and the valve body 6; Described cover plate 1 is connected valve body 6 tops by screw; Be connected with sealing gasket 4 between described cover plate 1 and the valve body 6; Outlet passageway I7 and outlet passageway II13 that described valve body 6 is provided with the gas-entered passageway 12 that is connected with the source of the gas (not shown) and is used for being connected with the cylinder (not shown); Described valve body 6 bottoms are connected with a plug screw 10; A sealed air chamber 8 is arranged between described plug screw 10 and the valve body 6; A vent plug that seals 9 is arranged in the described sealed air chamber 8; Be equipped with spring I11 between described vent plug 9 and the plug screw 10; Described vent plug 9 is withstanding under the effect of spring I11 on the valve body 6; Described valve body 6 is provided with guide channel 16; One end of described guide channel 16 communicates with gas-entered passageway 12, and its other end communicates with sealed air chamber 8; Described spool 3 is provided with exhaust passage 14; 14 bottoms, described exhaust passage communicate with outlet passageway I7 and outlet passageway II13, and its top communicates with the cavity 5 at valve body 6 tops; Described valve body 6 sidewalls are provided with the relief opening 15 that communicates with cavity 5.
Working principle of the present utility model is: when rotatable handle 2 moves down spool 3 promotion vent plugs 9,14 bottoms, exhaust passage can be close on the vent plug 9, at this moment, exhaust passage 14 is inoperative, gas begins in gas-entered passageway 12, guide channel 16 and sealed air chamber 8 flow into outlet passageway I7 and outlet passageway II13, finally enters in the cylinder (not shown) through outlet passageway I7 and outlet passageway II13; When opposite spin handle 2, spool 3 breaks away from vent plug 9, and at this moment, 14 moments of exhaust passage communicate with outlet passageway I7 and outlet passageway II13, and the gas in the cylinder finally discharges through relief opening 15 in the 14 inflow cavitys 5 of exhaust passage.
