Description

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. .

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
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
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
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
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
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
