【物品用途】;本創作物品係有關一種「殘壓排氣閥」，係設置在壓力流體供給源與流體壓機器之間，且遮斷從壓力流體供給源所供給之壓力流體，而可排出不希望殘留在流體壓機器內之壓力流體(產生殘壓之流體)的殘壓排氣閥。;在使用之際，首先利用未圖示之連接手段將未圖示之壓力流體供給源連接在壓力流體輸入口，同樣地將未圖示之流體壓機器連接在壓力流體輸出口。接著，以使連結壓力流體輸入口及壓力流體輸出口之線、與連結設置在把手之一對凸出部的線平行之方式旋轉把手時，短管閥會由於把手之旋轉而移動於把手內部，使壓力流體輸入口與壓力流體輸出口連通。結果，壓力流體供給源與流體壓機器藉由本創作物品連通之故，即在壓力流體供給源之驅動作用下將壓力流體供給至流體壓機器。復以使連結壓力流體輸入口與壓力流體輸出口之線、與連結設置在把手之一對凸出部之線正交之方式旋轉把手時，短管閥會移動於把手內部，使壓力流體輸入口與壓力流體輸出口之連通被遮斷，而連通壓力流體輸出口與壓力流體排出口。結果，具有不希望殘留在流體壓機器內之壓力(殘壓)的流體透過壓力流體輸出口從壓力流體排出口排出，此時，由於把手側鍵孔與罩蓋側鍵孔相吻合，因此將未圖示之掛鎖安裝在把手側鍵孔與罩蓋側鍵孔，而可防止把手之旋轉。藉由安裝掛鎖，得避免在排出具有不希望殘留在流體壓機器內之壓力(殘壓)的壓力流體之際，致第三者誤操作把手而將壓力流體供給至流體壓機器。;【創作特點】;本創作係有關於一種「殘壓排氣閥」之外形設計，該殘壓排氣閥係由本體、藉由螺絲固定在本體之上部的罩蓋、及連結在罩蓋之上部的把手所構成(參照參考圖(1))。在本體之內部收納有未圖示之短管閥，該短管閥係藉由把手之旋轉而沿著把手之軸線方向來回動作，並切換壓力流體之流路。在前述本體之短邊方向之一端部，形成有與未圖示之壓力流體供給源連接之壓力流體輸入口(參照參考圖(1))。在前述本體之短邊方向之另一端部，以與該壓力流體輸入口相對向之方式設置有壓力流體輸出口(參照參考圖(2))。在該壓力流體輸出口連接有未圖示之流體壓機器。再者，在前述本體之下表面，突出有用以排出具有不希望殘留在前述流體壓機器內之壓力(殘壓)的流體之大致六角柱狀的壓力流體排出口，在該壓力流體排出口之兩側，設置具有用以插入未圖示之螺栓且螺接本創作物品與托架(未圖示)之安裝孔的凸出部。在右側視圖及左側視圖中，壓力流體輸入口及壓力流體輸出口之周圍係形成為大致方形。在大致方形之左右端部，膨出有與未圖示之連接金屬具卡合之凸緣，本創作物品係藉由該連接金屬具與未圖示之壓力流體供給源或流體壓機器連結。;在前述本體之長邊方向的側面中央，設置有用以增加通過本體內部之壓力流體之有效剖面積的圓弧狀之膨出部。此外，在該膨出部之兩側上部，設置有用以確保供前述螺絲插入之母螺絲部(未圖示)之厚度的大致方形之加襯部。;在前述罩蓋之外周設置有2個罩蓋側鍵孔。前述把手係具有：大致圓筒部分；從大致圓筒部分之外周面突出之一對凸出部；及沿著該大致圓筒部分之外周面以板狀延伸於大致圓筒部分之前述罩蓋側的第1凸片、第2凸片、第3凸片及第4凸片。該等第1至第4凸片係沿著把手之圓周方向等間隔地形成，相鄰之凸片彼此係形成在沿著把手之圓周方向各旋轉90度之位置。第1凸片與第3凸片係隔著前述把手之大致圓筒部分而相對向，第2凸片與第4凸片係隔著前述把手之大致圓筒部分而相對向。在第1凸片與第3凸片設置有供該凸片貫通之把手側鍵孔。;顯示在各圖之表面部的大致水平平行狀細線、大致垂直平行狀細線、大致傾斜平行狀細線及大致圓孤狀細線皆係顯示立體表面之形狀的線。;參考圖(1)及(2)係顯示本創作各部件之說明。由上述構成本創作整體造形精巧別緻，具新穎獨特之視覺效果及創作性。[Use of the article]; This creative article is about a "residual pressure exhaust valve", which is set between the pressure fluid supply source and the fluid press, and blocks the pressure fluid supplied from the pressure fluid supply source, and can discharge the pressure fluid (fluid that generates residual pressure) that is not desired to remain in the fluid press.; When using it, first use the unillustrated connection means to connect the unillustrated pressure fluid supply source to the pressure fluid input port, and similarly connect the unillustrated fluid press to the pressure fluid output port. Next, when the handle is rotated in such a way that the line connecting the pressure fluid inlet and the pressure fluid outlet is parallel to the line connecting a pair of protrusions provided on the handle, the short-tube valve will move inside the handle due to the rotation of the handle, so that the pressure fluid inlet and the pressure fluid outlet are connected. As a result, the pressure fluid supply source and the fluid press are connected through the creative article, that is, the pressure fluid is supplied to the fluid press under the driving action of the pressure fluid supply source. When the handle is rotated in such a manner that the line connecting the pressure fluid inlet and the pressure fluid outlet is orthogonal to the line connecting a pair of protrusions provided on the handle, the short-tube valve moves inside the handle, so that the connection between the pressure fluid inlet and the pressure fluid outlet is blocked, and the pressure fluid outlet and the pressure fluid discharge outlet are connected. As a result, the fluid with the pressure (residual pressure) that is not desired to remain in the fluid press is discharged from the pressure fluid outlet through the pressure fluid outlet. At this time, since the handle side keyhole and the cover side keyhole coincide with each other, a hanging lock (not shown) is installed on the handle side keyhole and the cover side keyhole to prevent the handle from rotating. By installing the lock, it is possible to prevent a third party from mistakenly operating the handle and supplying the pressurized fluid to the fluid pressurizer when discharging the pressurized fluid with a pressure (residual pressure) that is not desired to remain in the fluid pressurizer. ;【Design Features】;This design is related to the appearance design of a "residual pressure exhaust valve", which is composed of a body, a cover fixed to the upper part of the body by screws, and a handle connected to the upper part of the cover (refer to reference figure (1)). A short-tube valve not shown is accommodated inside the body. The short-tube valve moves back and forth along the axial direction of the handle by rotating the handle and switches the flow path of the pressurized fluid. At one end of the short side direction of the aforementioned main body, there is formed a pressure fluid inlet connected to a pressure fluid supply source not shown in the figure (refer to reference figure (1)). At the other end of the short side direction of the aforementioned main body, there is provided a pressure fluid outlet (refer to reference figure (2)) in a manner opposite to the pressure fluid inlet. A fluid press not shown in the figure is connected to the pressure fluid outlet. Furthermore, on the lower surface of the aforementioned main body, there is protruding a roughly hexagonal columnar pressure fluid outlet for discharging a fluid having a pressure (residual pressure) that is not desired to remain in the aforementioned fluid press. On both sides of the pressure fluid outlet, there are provided protrusions having mounting holes for inserting bolts not shown in the figure and for screwing the present creative article and the bracket (not shown). In the right side view and the left side view, the periphery of the pressure fluid inlet and the pressure fluid outlet is formed into a roughly square shape. At the left and right ends of the roughly square shape, there are bulging flanges that engage with the connecting metal fixtures not shown in the figure. The present invention is connected to the pressure fluid supply source or fluid press machine not shown in the figure through the connecting metal fixtures. ; In the center of the side surface in the long side direction of the aforementioned main body, there is an arc-shaped bulging portion for increasing the effective cross-sectional area of the pressure fluid passing through the inside of the main body. In addition, at the upper parts of both sides of the bulging portion, there are roughly square lining portions for ensuring the thickness of the female screw portion (not shown) for inserting the aforementioned screw. ; Two cover side keyholes are provided on the outer periphery of the aforementioned cover. The handle comprises: a substantially cylindrical portion; a pair of protrusions protruding from the outer circumference of the substantially cylindrical portion; and the first, second, third and fourth protrusions extending in a plate-like manner along the outer circumference of the substantially cylindrical portion on the aforementioned cover side of the substantially cylindrical portion. The first to fourth protrusions are formed at equal intervals along the circumferential direction of the handle, and adjacent protrusions are formed at positions rotated 90 degrees along the circumferential direction of the handle. The first protrusion and the third protrusion are opposed to each other across the substantially cylindrical portion of the handle, and the second protrusion and the fourth protrusion are opposed to each other across the substantially cylindrical portion of the handle. The first and third protrusions are provided with handle side keyholes for the protrusions to pass through. ;The roughly horizontal parallel thin lines, roughly vertical parallel thin lines, roughly inclined parallel thin lines and roughly circular thin lines shown on the surface of each figure are all lines showing the shape of the three-dimensional surface. ;Refer to Figures (1) and (2) for the description of each component of this creation. The overall shape of this creation composed of the above is exquisite and unique, with novel and unique visual effects and creativity.
