Description

二向移動之閥件驅動裝置Two-way moving valve drive device

本創作係與閘閥有關，特別是指一種二向移動之閥件驅動裝置。This creation is related to gate valves, especially a two-way valve driving device.

中華民國第I503914號專利，揭露了一種雙向閘閥，該案主要是利用第一驅動單元來操作第一操作體，或是以及利用第二驅動單元來操作第二操作體，藉以使其推挽模組產生向左或向右的位移，進而使得第一密封板或第二密封板能對兩個入口進行選擇性的密封。The Republic of China Patent No. I503914 discloses a two-way gate valve. This case mainly uses a first drive unit to operate a first operating body, or a second drive unit to operate a second operating body, thereby making it push-pull die The group is displaced to the left or right, so that the first sealing plate or the second sealing plate can selectively seal the two inlets.

前述案件主要的技術特點在於，除了底部使用了空壓缸之外，在上層連接於空壓缸活塞桿的推挽模組的部分還使用到了類似曲臂的第一操作體及第二操作體。這是一種將位於兩個入口之間的密封板以選擇性的機構來向一側移動，藉以密封其中一個入口的技術。The main technical feature of the aforementioned case is that in addition to the air cylinder used at the bottom, the upper part of the push-pull module connected to the piston rod of the air cylinder also uses a first operating body and a second operating body similar to a crank arm. . This is a technique in which the sealing plate located between two entrances is moved to one side with a selective mechanism to seal one of the entrances.

由上可知，該案技術的機構較為複雜，零件繁多，組裝不易且容易有精度的問題。且其密封板的移動方式也是需要依賴例如第一操作體、旋轉軸與第一及第二密封板來產生旋轉之後的偏心側移動態，藉以使密封板能選擇性的向左或向右密封於兩個入口，此種動作方式較為複雜且準確度不高。It can be seen from the above that the technical mechanism of this case is relatively complicated, with many parts, difficult to assemble and easy to have accuracy problems.

該閥件49，固設於該三閥缸活塞桿45露出於該閥缸41的部分，本實施例中係設於該三閥缸活塞桿45的末端。The valve member 49 is fixed on the part of the three-valve cylinder piston rod 45 exposed from the valve cylinder 41. In this embodiment, it is installed at the end of the three-valve cylinder piston rod 45.

其中，該第一進氣通道14連通於該二氣室12的位置係對應位於該二活塞211,251的一端，該第二進氣通道18連通於該二氣室12的位置係對應位於該二活塞211,251的另一端，氣體由該第一進氣口13進入該二氣室12時，係將該第一活塞桿21及該第二活塞桿25推向該推出位置，氣體由該第二進氣口17進入該二氣室12時，係將該第一活塞桿21及該第二活塞桿25推向該縮回位置。此外，該推進通道43連通於各該閥缸氣室42的位置係對應位於各該閥缸活塞46的一端，該退回通道44連通於各該閥缸氣室42的位置係對應位於各該閥缸活塞46的另一端，氣體由該推進通道43進入各該閥缸氣室42時，係將各該閥缸活塞桿45向外推出，氣體由該退回通道44進入各該閥缸氣室42時，係將各該閥缸活塞桿45推回至縮回狀態。Wherein, the position where the first air intake passage 14 communicates with the second air chamber 12 is correspondingly located at one end of the two pistons 211, 251, and the position where the second air intake passage 18 communicates with the second air chamber 12 is correspondingly located at the second piston At the other end of 211 and 251, when gas enters the second gas chamber 12 from the first air inlet 13, the first piston rod 21 and the second piston rod 25 are pushed to the pushing position, and the gas is fed from the second air inlet When the port 17 enters the two air chambers 12, the first piston rod 21 and the second piston rod 25 are pushed to the retracted position.

在實際實施時，該第一進氣口13及該第二進氣口17可以分別設置一個氣嘴51，以方便外部的氣體源(圖中未示)連接。In actual implementation, the first air inlet 13 and the second air inlet 17 may be respectively provided with a gas nozzle 51 to facilitate the connection of an external gas source (not shown).

以上說明了本實施例的架構，接下來說明本實施例的操作動作。The architecture of this embodiment has been explained above, and the operation of this embodiment will be explained next.

如圖11所示，在使用前，先將本創作安裝於一閥口91旁。在未操作時，該第一活塞桿21以及該第二活塞桿25均位於該縮回位置，且該閥缸活塞桿45亦位於縮回的狀態，此時該閥件49即位於最低位置且處於縮回狀態。該閥口91即處於未封閉狀態。As shown in Fig. 11, before use, install this creation next to a valve port 91. When not operating, the first piston rod 21 and the second piston rod 25 are in the retracted position, and the valve cylinder piston rod 45 is also in the retracted state. At this time, the valve member 49 is at the lowest position and In a retracted state. The valve port 91 is in an unclosed state.

如圖3所示，欲將該閥口91封閉時，係執行封閉操作，其係使氣體由一該氣嘴51進入該第一進氣口13，進而進入該二氣室12，該第一活塞桿21及該第二活塞桿25即受推動而向該推出位置移動，此時該閥缸41即隨著該第一活塞桿21及該第二活塞桿25而移動，但此時由於該第一導桿31的該氣孔33尚未露出於該第一導桿31所在的氣室12，因此氣體還不會進入該氣孔33。該第一活塞桿21持續被推動而移動至該推出位置時，其狀態即如圖10及圖12所示。再如圖10及圖5所示，當該第一活塞桿21移動至該推出位置時，該氣孔33即會露出於該第一活塞桿21外，該氣孔33所在的該氣室12內的氣體即會進入該氣孔33，而經由該氣槽32、該第一流道22以及該推進通道43而流入該三閥缸氣室42，進而推動該閥缸活塞桿45向外推進而最終向外移動至最外端的位置，此時，該閥件49即蓋住該閥口91形成封閉效果，而形成如圖13的狀態。As shown in Figure 3, when the valve port 91 is to be closed, a closing operation is performed, which causes the gas to enter the first gas inlet 13 from a gas nozzle 51, and then into the second gas chamber 12. The piston rod 21 and the second piston rod 25 are pushed to move to the pushing position. At this time, the valve cylinder 41 moves with the first piston rod 21 and the second piston rod 25, but at this time due to the The air hole 33 of the first guide rod 31 has not yet been exposed to the air chamber 12 where the first guide rod 31 is located, so gas will not enter the air hole 33 yet. When the first piston rod 21 is continuously pushed to move to the pushing position, its state is as shown in FIGS. 10 and 12. As shown in Figures 10 and 5, when the first piston rod 21 moves to the push position, the air hole 33 is exposed outside the first piston rod 21, and the air hole 33 is located in the air chamber 12 The gas will then enter the air hole 33, and flow into the three-valve cylinder air chamber 42 through the air groove 32, the first flow passage 22 and the advancing passage 43, and then push the valve cylinder piston rod 45 outward and finally outward. Move to the outermost position. At this time, the valve member 49 covers the valve port 91 to form a closing effect, and the state as shown in FIG. 13 is formed.

如圖10及圖13所示，欲將該閥件49退回時，係執行退回操作，其係使氣體由另一個氣嘴51進入該第二進氣口17，進而進入該二氣室12，且也同時進入該導氣流道36，並經由該第二流道26以及該退回通道44而進入該三閥缸氣室42，進而藉由氣壓的推動而將該三閥缸活塞桿45推回縮回的位置，並將該第一活塞桿21及該第二活塞桿25推動至縮回位置。如此一來，該閥件49即又退回至前述如圖3所示的未操作的位置。As shown in Figures 10 and 13, when the valve member 49 is to be returned, a return operation is performed, which allows gas to enter the second air inlet 17 from another gas nozzle 51, and then into the second gas chamber 12. At the same time, it also enters the air guide passage 36, enters the three-valve cylinder air chamber 42 through the second flow path 26 and the retreat passage 44, and then pushes the three-valve cylinder piston rod 45 back by air pressure. And push the first piston rod 21 and the second piston rod 25 to the retracted position. As a result, the valve member 49 returns to the non-operated position as shown in FIG. 3.

前述的動作說明中，在執行封閉操作時，所形成的效果是該第一活塞桿21及該第二活塞桿25先上升至推出位置後，該三閥缸活塞桿45才伸出，而對於該閥件49來說，其動態則是該閥件49先上升，再平移至蓋住該閥口91。而在執行退回操作時，該閥件49則是縮回與下降同時進行。因此，在設計上，對於該第二進氣口17與該第二進氣通道18所形成的路徑上的最小口徑的部位，相較於該第二進氣口17、該導氣流道36、該第二流道26以及該退回通道44所形成的路徑上的最小口徑的部位而言，可以設計為口徑較小。這個設計可以讓氣體在進入該第二進氣通道18時較為不易，而在進入該退回通道44時較為容易，進而可以確保在退回操作時氣體會優先進入該退回通道44，使得該三閥缸活塞桿45先縮回至無法再縮回的位置後，氣體才會由再進入該第二進氣通道18來推動該第一活塞桿21及該第二活塞桿25下降，進而使該閥件49產生先平移縮回才下降的效果。本創作是利用一該氣嘴51與該第二進氣口17之間的縫隙來做為較小口徑的部位，並且使該氣嘴51與該導氣流道36之間直接連通而使得口徑大於該氣嘴51與該第二進氣口17之間的縫隙，形成上述的口徑關係，如此就可以在退操作時形成使該閥件49先平移縮回才下降的效果。In the foregoing action description, when the closing operation is performed, the effect formed is that after the first piston rod 21 and the second piston rod 25 first rise to the push-out position, the three-valve cylinder piston rod 45 extends, and for For the valve member 49, the dynamics is that the valve member 49 first rises and then translates to cover the valve port 91. When the retracting operation is performed, the valve member 49 retracts and descends simultaneously. Therefore, in terms of design, the smallest diameter portion of the path formed by the second air inlet 17 and the second air inlet passage 18 is compared with the second air inlet 17, the air guide channel 36, The smallest diameter portion of the path formed by the second flow passage 26 and the retreat passage 44 can be designed to have a smaller diameter. This design can make it more difficult for gas to enter the second intake passage 18, and easier to enter the retreat passage 44, thereby ensuring that the gas will preferentially enter the retreat passage 44 during the retreat operation, so that the three-valve cylinder After the piston rod 45 is first retracted to a position where it cannot be retracted, the gas will then enter the second intake passage 18 to push the first piston rod 21 and the second piston rod 25 down, thereby causing the valve member 49 produces the effect of first translation and retraction before descending. In this creation, a gap between the air nozzle 51 and the second air inlet 17 is used as a smaller diameter part, and the air nozzle 51 and the air flow duct 36 are directly connected to make the diameter larger than The gap between the air nozzle 51 and the second air inlet 17 forms the above-mentioned caliber relationship, so that the effect of causing the valve member 49 to first translate and retract before descending can be formed during the retracting operation.

綜上可知，本創作利用氣體流道的設計來使兩個方向的活塞桿分別移動，進而使該閥件49產生兩個方向上的移動動作，因此，本案並不是使用多個零件來產生機構上的旋轉或偏移，因此本案相較於先前技術而言具有更為精簡的零件數量，且本案在驅動閥件49的操作動作上較為簡單，且本案使用活塞桿在空壓缸上的伸縮移動，因此較機構件的偏擺或旋擺移動而言具有更較高的精準度。To sum up, this creation uses the design of the gas flow channel to move the piston rods in two directions separately, thereby causing the valve member 49 to move in two directions. Therefore, this case does not use multiple parts to generate the mechanism. Therefore, compared with the prior art, this case has a more streamlined number of parts, and the operation of driving valve 49 is simpler, and this case uses the expansion and contraction of the piston rod on the air cylinder Therefore, it has a higher accuracy than the deflection or swing movement of the mechanism.

須額外說明的是，在該第一進氣口13進氣時，該第二進氣口17即可以做為出氣使用，反之，在該第二進氣口17進氣時，該第一進氣口13即可以做為出氣使用。此外，為了氣密功能而設置油封(或O形環)乃屬習知技術，因此容不於本案中加以說明，而僅在圖式中予以表示出來，但這些油封的設置位置及方式並非本案之申請重點，不能用來限制本案之申請專利範圍。It should be additionally noted that when the first air inlet 13 takes in air, the second air inlet 17 can be used as air outlet. On the contrary, when the second air inlet 17 takes in air, the first inlet The air port 13 can be used as an air outlet. In addition, the installation of oil seals (or O-rings) for the purpose of airtightness is a conventional technology, so it cannot be described in this case, but is only shown in the drawings, but the location and manner of these oil seals are not in this case The key points of the application cannot be used to limit the scope of patent application in this case.
