【物品用途】;本物品為一種殘壓排氣閥，係設置在未圖示的壓力流體供給源與流體壓力機器之間，可切換為對流體壓力機器供給壓力流體的狀態，以及阻隔壓力流體對於流體壓力機器的供給並將殘留於流體壓力機器內之不要的壓力流體(產生殘壓的流體)往外部排出的狀態。;在使用時，首先，對壓力流體輸入通口連接未圖示的壓力流體供給源，對壓力流體輸出通口連接未圖示的流體壓力缸等流體壓力機器。;若向預定方向轉動把手，壓力流體輸入通口與壓力流體輸出通口就會連通，而對流體壓力機器供給壓力流體(供給狀態)。;若向與預定方向相反的方向轉動把手，壓力流體輸出通口與壓力流體排出通口就會連通，使殘留於流體壓力機器之內部的壓力流體向本物品的內部流入，並從壓力流體排出通口往外部排出(排氣狀態)。此時，把手側鎖孔位於主體罩蓋側鎖孔的正上方。若將例如掛鎖等鎖具安裝於把手側鎖孔與主體罩蓋側鎖孔，把手就會固定而防止把手的誤操作。;在把手的顯示部顯示把手的位置處於供給狀態或是處於排氣狀態。;【設計說明】;本設計物品之殘壓排氣閥包含：主體，覆蓋主體之上部的主體罩蓋，以及安裝於主體罩蓋之上部的把手(參照顯示各部名稱之參考立體圖1及顯示各部名稱之參考立體圖2)。;在主體之下部設有壓力流體排出通口，在主體之側面設有壓力流體輸入通口與壓力流體輸出通口。;在主體罩蓋之側面設有剖面矩形的開口部。該開口部係與主體罩蓋上部之主體罩蓋側鎖孔連通。;在把手設有顯示部與把手側鎖孔。;本創作之特徵在於「殘壓排氣閥」的整體形狀。[Use of article] This article is a residual pressure exhaust valve, which is installed between a pressure fluid supply source and a fluid pressure machine (not shown). It can be switched to a state of supplying pressure fluid to the fluid pressure machine and blocking the pressure fluid. A state that supplies fluid pressure equipment and discharges unnecessary pressure fluid (fluid that generates residual pressure) remaining in the fluid pressure equipment to the outside. ; During use, first, connect a pressure fluid supply source (not shown) to the pressure fluid input port, and connect a fluid pressure device such as a fluid pressure cylinder (not shown) to the pressure fluid output port. ; When the handle is turned in a predetermined direction, the pressure fluid input port and the pressure fluid output port are connected, and the pressure fluid is supplied to the fluid pressure machine (supply state). ; If the handle is turned in the opposite direction to the predetermined direction, the pressure fluid output port and the pressure fluid discharge port will be connected, allowing the pressure fluid remaining inside the fluid pressure machine to flow into the inside of the article and be discharged from the pressure fluid The port discharges to the outside (exhaust state). At this time, the handle side lock hole is located directly above the main body cover side lock hole. If a lock such as a padlock is installed in the lock hole on the handle side and the main cover side lock hole, the handle will be fixed to prevent misoperation of the handle. ;The display part of the handle shows whether the position of the handle is in the supply state or the exhaust state. ;[Design description];The residual pressure exhaust valve of this design article includes: a main body, a main body cover covering the upper part of the main body, and a handle installed on the upper part of the main body cover (refer to the reference perspective view 1 showing the names of each part and showing the parts Reference stereogram 2) for the name. ; A pressure fluid discharge port is provided at the lower part of the main body, and a pressure fluid input port and a pressure fluid output port are provided on the side of the main body. ; An opening with a rectangular cross-section is provided on the side of the main cover. The opening is connected with the keyhole on the side of the main body cover on the upper part of the main body cover. ; The handle is provided with a display part and a lock hole on the side of the handle. ;The characteristic of this creation is the overall shape of the "residual pressure exhaust valve".
