550344 A7 ____B7_ 五、發明説明（1 ) 技術領域 背景技藝 (請先閱讀背面之注意事項再填寫本頁) 在以往復式活塞泵抽送各種粘度的液體時發現，液體 的粘度越高，則液體可以越快速流動通過一給定的開口。 當開口是一泵的球閥時，且當抽送高粘度的液體時，吸取 以後的內部液體壓力由於吸入過多的液體流而增加或增強 。這是因爲使用於高粘度液體的開口尺寸與使用於低粘度 液體者-其壓力不增強-相同。內部液體壓力之此增加需 要更多的能量以補償壓力變動，於是總效率減小。 發明揭示 經濟部智慧財產局員工消費合作社印製 本發明允許使用者調整一泵中的球行程，以更精確容 納較高或較低粘度的液體。如果使用者能夠減小開口的尺 寸，則較少的液體將進入系統，且高粘度液體不再產生壓 力增強。然而，如果正在抽送低粘度液體，則需要較大的 開口，以避免耗費過多的能量，以增加吸取。本發明簡單 地允許使用者在吸取期間調整開口的最大尺寸，以匹配所 抽送之液體的粘度，於是，如果正確使用，可增加效率。 球在維持泵中之適當液體壓力時某種程度地充當止動 器，只有在內部吸力大至足以舉起球時，才允許某些液體 進入系統。在抽送不同粘度的液體時，可變尺寸的開口較 佳，以維持恆定的內部壓力。一液體的粘度越高，則越小 的開口較佳，以允許某些液體進入系統，且維持內部壓力 。本發明簡單地允許使用者將球行程隔板***球的上方或 本紙張尺度適用中國國家榇準（匸奶）八4規格（210'乂297公釐） 厂4 - 550344 五、發明説明（2 τ方’其將使液體必須通過的開口增大或減小。 從下列說明，配合附圖，可以更明白本發明的這些及 其他目的與優點，其中相同的參考符號標示若干視圖中相 同或類似的零件。 圖式簡單說明 圖1是顯示吸取止回閥系統的分解圖。 經濟部智慧財產局員工消費合作社印製 符號說明 5 系統 6 缸 7 下外殻 9 墊座 10 止回閥 11 球止動件 13 球 15 可調整塡片 17 穴 21 臂 執行發明的最佳模式 本發明允許使用者調整一泵中的球行程，以更·精確容 納較高或較低粘度的液體。抽送至系統中的液體經由下外 殻7及其中的穴π進入泵。此液體由於內部吸力而上升，直 本紙張尺度適用中國國家榡隼（CNS ) Α4規格（210X297公釐） (請先閱讀背面之注意事項再填寫本頁) 裝· 、1Τ 550344 A7 B7 五、發明説明（3 ) 到它們到達止回閥1 0爲止。只有當球丨3被舉起且未貼合於 墊座9中，液體才可進入泵，因爲其產生有效的堵塞。當內 部吸力大至足以舉起球1 3，以致於它不再貼合於墊座9中時 ，液體可通過墊座9及向上進入泵缸6。球1 3由一球止動件 Π防止進入缸6，球止動件丨丨是一環，其將臂2 1延伸穿過穴 ’俾使球不能通過，但是不阻礙液體的流動。 此處實施之本發明係添加環形的可調整塡片1 5，且其 可放在止回閥1 0的上方或下方，以致於墊座9與球1 3之間的 空間在液體流動通過時可以調整及控制。如果塡片15*** 止回閥10下方，則球13在墊座9與球止動臂21之間具有完整 的行程範圍。如果塡片1 5添加於止回閥1 〇上方，則球止動 臂2 1與墊座9之間只許有較小的空間，於是減小在某一時間 進入系統5的液體數量。 所慮及的是可對於可調整入口球行程作各種改變及修 改’不會偏離下列申請專利範圍界定之本發明的精神和範 疇。 -----：1 ——^ !
