【物品用途】;本物品係關於一種「閥」，係設置於供氣體或液體等流體流通之管路，用以控制或限制流體之流動或流量。;在使用時，首先，係將一對端口部分別連接於流體的管路，將未圖示之壓力流體供應源連接於壓力流體導出導入端口。接著，當對壓力流體導出導入端口供給壓力流體時，在壓力流體的供給作用下，未圖示之活塞會抵抗彈性構件的彈力而朝從主體本體離開的方向變位。若壓力流體的供給停止，則活塞會藉由彈性構件的彈力朝主體本體方向變位，而回歸至原位置。一體連結於活塞的閥體會伴隨著活塞的變位而抵接於閥座或從閥座離開，藉此進行流體流路的開閉。;設置於作動缸之另一端側的小突起會伴隨著活塞的變位，在閉閥狀態時埋入於作動缸的端面，在開閥狀態時從從作動缸的端面突出。接觸本物品的使用者，係可藉由從作動缸之端面突出的小突起的長度來辨識流體流路的開閉狀態。;【設計說明】;如立體圖、前視圖、後視圖、左側視圖、右側視圖、俯視圖、;及仰視圖等所示，如是構成整體外觀具新穎性及特異視覺效果之設計。;本設計之閥係具有：主體本體，係於兩端具有大致圓筒形狀的一對端口部；及作動缸，係從主體本體之中央部突出設置(參照參考圖(1)及(2))。;在主體本體的內部形成有供流體流通之流體流路，且一對端口部經由該流體流路彼此連通。在流體流路之中途設有閥座。;作動缸係呈現隅角部彎曲之大致長方體狀。作動缸之軸線方向一端側係連接設置於主體本體的中央部，使作動缸之軸線與一端口之中心線成為銳角。在作動缸之軸線方向另一端側的端面，係設置有大致圓柱狀的小突起，用以顯示流體流路之開閉狀態。;在作動缸之各周壁，係沿著軸線方向設有2條感測器安裝溝。在作動缸之各周壁之中之顯示於俯視圖之作動缸之周壁，係在前述2條感測器安裝溝之間設有壓力流體導出導入端口。;在作動缸之內部係收容有：朝軸線方向變位自如地設置之未圖示的活塞；以及，將活塞朝主體本體方向推壓之未圖示的彈性構件。在活塞之朝向主體本體的一端側係連結有未圖示之閥桿的一端，在活塞之另一端側係連結有前述小突起。在閥桿之未與活塞連結的另一端側，係連結有未圖示的閥體。;「參考圖(1)」及「參考圖(2)」中分別顯示各部名稱。[Use of the article] This article is about a "valve" which is installed in a pipeline for the circulation of fluids such as gas or liquid to control or limit the flow or flow rate of the fluid. When in use, first, a pair of port parts are respectively connected to the pipeline of the fluid, and a pressure fluid supply source not shown is connected to the pressure fluid outlet and inlet port. Then, when the pressure fluid is supplied to the pressure fluid outlet and inlet port, under the action of the supply of the pressure fluid, the piston not shown will resist the elastic force of the elastic member and displace in the direction away from the main body. If the supply of the pressure fluid stops, the piston will be displaced toward the main body by the elastic force of the elastic member and return to the original position. The valve body integrally connected to the piston will abut against the valve seat or leave the valve seat as the piston moves, thereby opening and closing the fluid flow path. The small protrusion provided on the other end of the actuator will follow the displacement of the piston. When the valve is closed, it is embedded in the end face of the actuator, and when the valve is open, it protrudes from the end face of the actuator. Users who touch this product can identify the open and closed state of the fluid flow path by the length of the small protrusion protruding from the end face of the actuator. [Design Description] As shown in the three-dimensional view, front view, rear view, left side view, right side view, top view, and bottom view, the overall appearance is novel and has a unique visual effect. ;The valve of this design comprises: a main body having a pair of port portions in a roughly cylindrical shape at both ends; and an actuator cylinder protruding from the central portion of the main body (refer to reference figures (1) and (2)). ;A fluid flow path for fluid circulation is formed inside the main body, and the pair of port portions are connected to each other via the fluid flow path. A valve seat is provided in the middle of the fluid flow path. ;The actuator cylinder is roughly rectangular with bent corners. One end side of the actuator cylinder in the axial direction is connected to the central portion of the main body so that the axis of the actuator cylinder forms an acute angle with the center line of one port. On the end face of the other end side of the actuator cylinder in the axial direction, a small roughly cylindrical protrusion is provided to indicate the open or closed state of the fluid flow path. ;Two sensor mounting grooves are provided along the axial direction on each peripheral wall of the actuator cylinder. Among the peripheral walls of the actuator cylinder, the peripheral wall of the actuator cylinder shown in the top view is provided with a pressure fluid outlet and inlet port between the two aforementioned sensor mounting grooves. ;The interior of the actuator cylinder accommodates: a piston (not shown) which is freely displaceable in the axial direction; and an elastic member (not shown) which pushes the piston toward the main body. One end of a valve rod (not shown) is connected to the end of the piston facing the main body, and the aforementioned small protrusion is connected to the other end of the piston. A valve body (not shown) is connected to the other end of the valve rod that is not connected to the piston. ; The names of each part are shown in "Reference Figure (1)" and "Reference Figure (2)".
