上％座92，及分別設置在該下閥座5之第一、二連接孔5ι 52中的一第一下環座93與一第二下環座94。該第一閥 桿3之閥片33是介於該第一上、下環座91、93之間，該 第二閥桿4之閥片43是亦介於該第二上、下環座92、94 之間。该第一、二上環座91、92與該第一、二下環座％、 之口裎均小於該二閥片33、43的外徑。當該第一、二閥 才干3、4上下移動時，即能對應地封閉該第一、二上環座μ 、92與該第一、二下環93、94。 在該較佳實施例中，該第―、二上環座91、92是獨立 製造:但也可以與該„ 2 —體成型。同樣地，該第一、 下裒座93 94除了如本實施例為獨立製造，當然也可以 與該下閥座5 -體成型，不應以此為限。 如圖5所7^，並配合目3，當該電磁單元8之電磁線圈 '未通電時，藉由該彈性件84的彈力，使該塞桿μ塞抵 於m道63的孔口。在氣體從該下閥座5之進氣通道 53通入時，氣體會通過該第—連通孔51貞該第—下環座 93 ’而流至該第一通道23之第一下段232中，並將該第一 11 M316957 閥才干3向上推移，使該第一閥桿3之閥片34塞住該第一上 環座91的孔口，而使氣體無法進入該第一上段231，避免 氣體流出該排氣孔29，所以全部的氣體只能從該第一輸氣 孔27輸出，進而能驅動一致動器（圖未示） 同時’在氣體流通入該第一通道23之第一下段232時 ，有小部分的氣體會經該第二内流道28而進入該第二通道 24之第二上段241中。因為該第二閥桿4之活塞42截面積 大於該第二上環座92之孔徑，所以該第二閥桿4會被向下 推移’使其閥片44能封抵該第二下環座94之孔口，以阻 擒軋體從此處進入該第二通道24之第二下段242中。由該 致動器排出的氣體則可經由該第二輸氣孔28進入該第二下 段242中’再從該排氣孔29排出。 另外’因為該塞桿83塞抵於該上内流道63的孔口， 因此，從該下内流道54流入該第一内流道25的氣體會被 塞住，無法進入該上閥蓋6之容置槽61中，也就不能推動 該第一閥桿3向下移動。 如圖6所示’並配合圖3，當該電磁單元8的電磁線圈 82通電時，會吸移該塞桿63，使其不再塞抵住該上内流道 63的孔口，此時，充滿於該第一内流道25内的氣體，就可 以經由該容置槽61、該通孔62而流入該第一通道23之第 上段231中。同樣地，由於該第一閥桿3之活塞32的截 面積大於該第一下環座93之孔徑，因此該第一閥桿3會被 往下推移，而使其閥片34抵塞住該第一下環座93的孔口 使得氣體無法進到該第一通道23之第一下段232内，而 12 M316957 阻斷從该第一輸氣孔27排出氣體。因此，該第一下段2w 内的氣體就無法再經由該第二内流道26進入該第二通道24 之第一上& 241中，該第二閥桿4立刻會被從該第二連通 孔52進入的氣體向上推移，並使其閥片44塞住該第二上 %座92的孔口，此時的氣體只能從該第二輸氣孔排出 ，就不再從該第一輸氣孔27輸出，藉此達到氣體切換的作 用。 由上述說明可知，本新型之氣壓用切換閥裝置，是讓 該第一、二閥桿3、4分別於該第一、二通道23、24内上 下切換移動，利用該第一、二内流道25、26與該上、下内 流迢63、54為導引小部分氣體流動，用以切換該第一、二 閥桿3、4的位置’利用該第―、二閥桿3、4是並排的設 計，以縮小整體的長度。而且，該第一、二連通孔51、52 與該第一、二輸氣孔27、28的孔徑在位置上較不受到限制 ’可以開没大尺寸的孔徑。再加上，氣體於該閥體2内流 動的動線彎折程度較小（約為9〇。的轉角）。相較於習知的設 計，本新型在整體流量確實可以增加不少，進而能加快反 應的速度。在本新型應用在工具母機之進退刀具作業時， 可以節省不少移動的時間，以縮短製作時程。再者，因為 整體的體積也較小，在安裝上與使用上均相當方便。 歸納上述，透過本新型之氣壓用換向閥裝置的設計， 能加大氣體流量，而使反應更為迅速，體積小，於安裝與 使用上均較為方便，故確實能達到本新型之目的。 惟以上所述者，僅為本新型之較佳實施例而已，當不 13 M316957 月匕以此限定本新型實施之範圍，即大凡依本新型申請專利 範圍及新型說明内容所作之簡單的等效變化與修飾，皆仍 屬本新型專利涵蓋之範圍内。 【圖式簡單說明】 圖1是一剖面示意圖，說明一習知之氣壓用換向間裝 置’ 一電磁線圈未作動之態樣；The upper seat 92 and the first lower ring seat 93 and the second lower ring seat 94 are respectively disposed in the first and second connecting holes 5ι 52 of the lower valve seat 5. The valve piece 33 of the first valve stem 3 is interposed between the first upper and lower ring seats 91, 93, and the valve piece 43 of the second valve stem 4 is also interposed between the second upper and lower ring seats 92. Between 94. The first and second upper ring seats 91, 92 and the first and second lower ring seats are both smaller than the outer diameters of the two valve plates 33, 43. When the first and second valve members 3, 4 are moved up and down, the first and second upper ring seats μ, 92 and the first and second lower rings 93, 94 can be closed correspondingly. In the preferred embodiment, the first and second upper ring seats 91, 92 are manufactured separately: but can also be formed with the body. Similarly, the first and lower squats 93 94 are identical to the embodiment. For the independent manufacture, of course, it can also be formed with the lower valve seat, and should not be limited thereto. As shown in Fig. 5, and with the purpose of 3, when the electromagnetic coil of the electromagnetic unit 8 is not energized, Due to the elastic force of the elastic member 84, the plug rod is plugged against the orifice of the m-channel 63. When the gas is introduced from the intake passage 53 of the lower valve seat 5, the gas passes through the first communication hole 51. The first lower ring seat 93' flows into the first lower section 232 of the first passage 23, and the first 11 M316957 valve stem 3 is pushed upward to plug the valve piece 34 of the first valve stem 3 The orifice of the first upper ring seat 91 prevents the gas from entering the first upper section 231, and the gas is prevented from flowing out of the exhaust hole 29, so that all the gas can only be output from the first gas transmission hole 27, thereby driving the same The actuator (not shown) simultaneously 'when the gas flows into the first lower section 232 of the first passage 23, a small portion of the gas passes through the second inflow The second valve section 28 enters the second upper section 241 of the second passage 24. Since the cross-sectional area of the piston 42 of the second valve stem 4 is larger than the aperture of the second upper ring seat 92, the second valve stem 4 is pushed downward. 'Let the valve plate 44 seal against the aperture of the second lower ring seat 94 to block the rolling body from entering the second lower section 242 of the second passage 24. The gas discharged by the actuator is The second air inlet hole 28 enters the second lower section 242 and is discharged from the air outlet hole 29. In addition, since the plug rod 83 is plugged against the opening of the upper inner flow path 63, from the bottom The gas flowing into the first inner flow passage 25 by the inner flow passage 54 is blocked, and cannot enter the accommodating groove 61 of the upper valve cover 6, so that the first valve stem 3 cannot be pushed downward. As shown in Fig. 3, when the electromagnetic coil 82 of the electromagnetic unit 8 is energized, the plug rod 63 is sucked so as not to be plugged against the opening of the upper inner flow passage 63, at this time, full The gas in the first inner flow passage 25 can flow into the upper portion 231 of the first passage 23 via the accommodating groove 61 and the through hole 62. Similarly, since the first The cross-sectional area of the piston 32 of the valve stem 3 is larger than the diameter of the first lower ring seat 93, so that the first valve stem 3 is pushed downward, and the valve plate 34 is blocked against the first lower ring seat 93. The orifice prevents gas from entering the first lower section 232 of the first passage 23, and 12 M316957 blocks the discharge of gas from the first gas passage 27. Therefore, the gas in the first lower section 2w can no longer be Entering the first upper & 241 of the second passage 24 via the second inner flow passage 26, the second valve stem 4 is immediately pushed upward by the gas entering from the second communication hole 52, and the valve is made The plug of the second upper seat 92 is plugged, and the gas at this time can only be discharged from the second air hole, and is no longer outputted from the first air hole 27, thereby achieving gas switching. As can be seen from the above description, the air pressure switching valve device of the present invention allows the first and second valve stems 3 and 4 to be vertically moved in the first and second passages 23 and 24, and the first and second inflows are utilized. The passages 25, 26 and the upper and lower inner flow ports 63, 54 guide a small portion of the gas flow for switching the positions of the first and second valve stems 3, 4 'using the first and second valve stems 3, 4 It is a side-by-side design to reduce the overall length. Further, the first and second communication holes 51, 52 and the apertures of the first and second air holes 27, 28 are less restricted in position, and the aperture of the large size can be opened. Further, the moving line of the gas flowing in the valve body 2 is less curved (a corner of about 9 〇). Compared with the conventional design, the present invention can indeed increase the overall flow rate, thereby speeding up the reaction. When the new application is applied to the advance and retreat tool of the tool main machine, a lot of moving time can be saved to shorten the production time. Moreover, because the overall volume is also small, it is quite convenient to install and use. In summary, the design of the air pressure reversing valve device of the present invention can increase the gas flow rate, and the reaction is more rapid, the volume is small, and it is convenient to install and use, so the purpose of the present invention can be achieved. However, the above is only a preferred embodiment of the present invention, and does not limit the scope of the present invention to the extent that it is based on the scope of the novel application and the novel description. Changes and modifications are still within the scope of this new patent.
