Background technique
Two-position three way pneumatic on-off valve is a kind of as pneumatic element, is widely used, well known common.At present, Pneumatic two-position three-way formula high-speed switch valve, adopts seat valve formula structure more, via spool and valve body, jointly forms air-flow path, and the sealing configuration of the kinematic pair in valve body adopts motive sealing (mostly being rubber parts) structure more.Arrange like this, because high-speed switch valve kinematic pair frequency of okperation is higher, the number of times that motion is switched is more, and motive sealing exists following defect and deficiency: 1. motive sealing fatigue damage is large, the poor air-tightness of product, thus affect quality of product; 2 motive sealing friction factor are larger, and kinetic equation loss is large.
Model utility content
The purpose of this utility model is for the defect of prior art and deficiency, provides a kind of structure to arrange rationally, adopts the sliding bush type two-position three way Pneumatic high-speed switch valve of static seal structure.
For achieving the above object, the utility model is by the following technical solutions:
A kind of sliding bush type two-position three way Pneumatic high-speed switch valve described in the utility model, comprise valve body, in described valve body, form valve pocket, described valve body is provided with suction port, relief opening A and relief opening B, described relief opening A is communicated in valve pocket top by through hole A, described suction port is communicated in valve pocket top, described valve pocket inwall is provided with Sealing, in described valve pocket, form fixed block, in described fixed block, be provided with the through hole B corresponding with through hole A, described through hole B is communicated with relief opening B, between described fixed block and Sealing, be provided with sealed sliding grip assembly, between described sealed sliding grip assembly and fixed block, be provided with Returnning spring.
Wherein, described sealed sliding grip assembly comprises sliding sleeve, is located at the filler plug at sliding sleeve top and is located at sliding sleeve bottom armature part, and described filler plug is located between through hole A and through hole B, and described Returnning spring is located between sliding sleeve and fixed block.
Further, described valve body two bottom sides is arranged with fixed hole A and fixed hole B.
Further, described suction port, relief opening A and relief opening B are located on the same sidewall of valve body.
Further, described filler plug is rubber filling plug.
The utility model beneficial effect is: between fixed block described in the utility model and Sealing, be provided with sealed sliding grip assembly, also there is sealed sliding grip assembly to be located between through hole B and through hole A, in sealing pair structure, motive sealing is not set, greatly improved operating life of the present utility model, reduce kinetic friction, played energy-conservation effect.

Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1 to Figure 3, a kind of sliding bush type two-position three way Pneumatic high-speed switch valve described in the utility model, comprises valve body 2, and described valve body 2 two bottom sides are arranged with fixed hole A13 and fixed hole B14, for the utility model valve body 2 is fixed on to electromagnet 12.
In described valve body 2, form valve pocket 18, described valve body 2 is provided with suction port 9 relief opening A8 and relief opening B10, described relief opening A8 is communicated in valve pocket 18 tops by through hole A17, described suction port 9 is communicated in valve pocket 18 tops, in described valve pocket 18, form fixed block 4, in described fixed block 4, be provided with the through hole B15 corresponding with through hole A17, described through hole B15 is communicated with relief opening B10.It should be noted that, described suction port 9, relief opening A8 and relief opening B10 are located on the same sidewall of valve body 2, arrange like this, are convenient to pipeline installing and arrange, and can effectively increase the wiring effect of pipeline.
Described valve pocket 18 inwalls are provided with Sealing 16, and particularly, peripheral upper and lower two parts of described Sealing 16 are connected with valve pocket 18 inner wall sealings with seal ring B11 by seal ring A3 respectively.
Between described fixed block 4 and Sealing 16, be provided with sealed sliding grip assembly, between described sealed sliding grip assembly and fixed block 4, be provided with Returnning spring 6.Particularly, described sealed sliding grip assembly comprises sliding sleeve 5, is located at the filler plug 7 at sliding sleeve 5 tops and is located at sliding sleeve 5 bottom armature parts 1, and described filler plug 7 is located between through hole A17 and through hole B15, and described Returnning spring 6 is located between sliding sleeve 5 and fixed block 4.Described filler plug 7 is rubber filling plug.
Working principle: the utility model is when original state, coil no electric circuit on electromagnet 12, now, Returnning spring 6 is by sliding sleeve 5 jack-up, filler plug 7 sealing through hole A17, the gas via through holes B15 entering in the utility model valve pocket 18 from suction port 9 discharges from relief opening B10.In the time of need to switching relief opening, to coil electricity on electromagnet 12, on electromagnet 12, produce magnetic force, attract armature part 1, by armature part 1, drive sliding sleeve 5 and filler plug 7 to move down together, filler plug 7 is separated with through hole A17, seals through hole B15 simultaneously, now, gas is discharged through relief opening A8 from through hole A17.
The utility model, when switching relief opening, does not have motive sealing between sealing pair, products air tightness has obtained larger raising, and friction factor reduces simultaneously, and switching flexibility ratio increases.
The above is only better embodiment of the present utility model, and the equivalence of doing according to structure, feature and principle described in the utility model patent claim therefore all changes or modifies, and is included in the utility model patent claim.
