Description
本發明與閘閥有關，特別是指一種利用彈力啟閉之閘閥。The present invention relates to gate valves, and in particular refers to a gate valve that utilizes elastic force to open and close.
CN107923554A專利案所揭露的真空閥在滾輪支架從打開位置移動至中間位置時，第一板和第二板被滾輪支架帶動；在滾輪支架從中間位置移動至關閉位置時，第一板和第二板沿移動方向的進一步移動被鎖止，而且，第一擴張滾輪和第二擴張滾輪沿著內凹的邊沿移動，並且在此情況下，第一板和第二板平行於擴張方向彼此分開，其中的第一板和第二板通過安置在第一板的第一彈簧臂和安置在第二板的第二彈簧臂而頂壓到第一擴張滾輪和第二擴張滾輪。In the vacuum valve disclosed in the CN107923554A patent case, when the roller bracket moves from the open position to the middle position, the first plate and the second plate are driven by the roller bracket; when the roller bracket moves from the middle position to the closed position, the first plate and the second plate Further movement of the plate in the direction of movement is blocked, and the first expansion roller and the second expansion roller move along the concave edge, and in this case the first plate and the second plate are separated from each other parallel to the expansion direction, The first plate and the second plate are pressed against the first expansion roller and the second expansion roller by a first spring arm disposed on the first plate and a second spring arm disposed on the second plate.

彈性組件66在本實施例中具有三彈性件68a、68b、68c，各彈性件68a、68b、68c具有二相對之彈性部70與一彈性定位部72，彈性定位部72一體地連接於該等彈性部70之底端，中間彈性件68b之該等彈性部70的長度大於左右二彈性件68a、68c之該等彈性部70的長度，使得該等彈性件68a、68b、68c的彈性部70具有不同的彈性係數，且中間彈性件68b之各彈性部70的底端具有一鄰設於彈性定位部72之長條孔74。彈性組件66更具有二支撐板76，其中一支撐板76利用四螺絲762固定於該等彈性件68a、68b、68c之其中一彈性部70的頂端及其中一該閘板56，另外一支撐板76利用四螺絲764與四螺帽766固定於該等彈性件68a、68b、68c之另外一彈性部70的頂端，該等螺絲764的頭部固定於另外一閘板56的四個沉頭孔64內，藉此，該等閘板56透過彈性組件66結合在一起。此外，如圖3及圖4所示，該等彈性件68a、68b、68c由下而上套設於傳動座42且有一部分位於鏤空槽44內，並且讓中間彈性件68b之彈性定位部72凸出於傳動座42下方，另外以中間彈性件68b之該等長條孔74套設於傳動件48之該等傳動凸部50，使得傳動座42在上下位移的過程中能帶動彈性組件66，再由彈性組件66帶動該等閘板56。In this embodiment, the
在實際運作時，首先如圖1及圖4所示，流體壓缸30之驅動軸34將傳動座42保持於如圖4及圖5所示之第一位置P1，此時的該等閘板56與彈性組件66皆位於腔室23內，使該等閥口24呈現開啟的狀態。During actual operation, first, as shown in Figures 1 and 4, the driving
若要關閉該等閥口24時，流體壓缸30之驅動軸34帶動傳動座42從如圖4及圖5所示之第一位置P1下降至如圖6及圖7所示之第二位置P2，在下降過程中，傳動座42透過彈性組件66同步帶動該等閘板56下降，當中間彈性件68b之彈性定位部72抵接於定位板29時即產生緩衝定位效果，以吸收閘板單元40施加於閥體20的衝擊力，此時該等閘板56正對於該等閥口24。When the
當該等閘板56對準該等閥口24後，流體壓缸30之驅動軸34仍持續推動傳動座42，此時的滾珠46會從深度較深的第一段60被帶往深度較淺的第二段62，當傳動座42到達如圖6及圖7所示之第二位置P2時，滾珠46該等閘板56往外推頂，使該等閘板56之間的距離增加，進而使該等閘板56密封該等閥口24(如圖8所示)，此時該等彈性件68a、68b、68c之該等彈性部70會被該等閘板56所撐開，以蓄積彈性回復力量；反之，當流體壓缸30之驅動軸34反向作動時，滾珠46會從深度較淺的第二段62被帶往深度較深的第一段60，以釋放施加於該等閘板56的推頂力量，此時藉助該等彈性件68a、68b、68c之該等彈性部70的彈性回復力量，使該等閘板56相互靠近而減少彼此之間的距離，以解除該等閘板56與該等閥口24之間的密封效果。直到滾珠46卡設於第一段60時，該等閘板56即可被流體壓缸30之驅動軸34帶往至如圖4及圖5所示的第一位置P1，進而開啟該等閥口24(如圖1所示)。When the

As shown in Figures 9 and 10, in the second embodiment of the present invention, the
綜上所陳，本發明之閘閥10可以根據實際需要(例如不同規格大小)調整彈性件68a、68b、68c、80的數量，並利用不同彈性係數的結構設計，進而對應調整彈性件68a、68b、68c、80所提供的回彈力量，因此在適應性方面的表現較佳。另外，本發明所提供的閘板56在作動方面較為順暢，使作業效率能有所提升，再加上整體組成構件較為單純，所以可達到降低製造成本的目的。To sum up, the
