【物品用途】;本設計之物品係將泵、閥、蓄壓器、過濾器、流量計、壓力感測器及配管區塊等兩個流體設備加以連接時使用的墊圈。如顯示出使用狀態的剖視參考圖1所示，本創作之物品包含：成對之圓環狀的徑內側壓入部，形成於軸向兩側的徑內側；及成對之圓筒狀的徑外側壓入部，形成於軸向兩側的徑外側。;成對之徑內側壓入部，分別藉由壓入至形成於兩個流體設備的流道孔的連接端部的徑內側密封槽，而作為防止流體洩漏的第一級密封來發揮功能。成對之徑外側壓入部，分別藉由壓入至形成於兩流體設備端面的圓筒狀徑外側密封槽，而作為防止流體洩漏的第二級密封來發揮功能。;如顯示出使用狀態的剖視參考圖2所示，本設計之物品的外周面形成有環狀槽，在墊圈的軸向一側的徑內側壓入部及徑外側壓入部係壓入至一邊的流體設備的徑內側密封槽及徑外側密封槽的狀態下，可藉由將手指或治具勾於墊圈的環狀槽並往軸向外側拉扯，而將墊圈自該流體裝置取下。;【設計說明】;本設計如圖式所示，其中，後視圖因與前視圖相同，仰視圖因與俯視圖相同，左側視圖因與右側視圖相同，故省略。[Use of article]; The article designed in this design is a gasket used to connect two fluid equipment such as pumps, valves, pressure accumulators, filters, flow meters, pressure sensors and piping blocks. As shown in the cross-sectional reference figure 1 showing the state of use, the article of this invention includes: a pair of annular radially inner press-fitted parts formed on the radially inner sides of both sides in the axial direction; and a pair of cylindrical The radially outer press-fitted portions are formed on the radially outer sides of both sides in the axial direction. The pair of radially inner press-fitted parts function as a first-stage seal to prevent fluid leakage by being press-fitted into radially inner seal grooves formed at the connecting ends of the flow passage holes of two fluid equipment. The paired diametrically outer press-fitted portions function as secondary seals that prevent fluid leakage by being press-fitted into cylindrical diametrically outer seal grooves formed on the end surfaces of both fluid devices. ; As shown in Figure 2, a cross-sectional view showing the state of use, an annular groove is formed on the outer circumferential surface of the article of this design, and the radially inner press-fitting portion and the radial outer press-fitting portion are press-fitted to one side on the axial side of the washer When the inside and outside sealing grooves of a fluid device are in place, the gasket can be removed from the fluid device by hooking a finger or a jig into the annular groove of the gasket and pulling axially outward. ;[Design Description];This design is as shown in the figure. The rear view is the same as the front view, the bottom view is the same as the top view, and the left side view is the same as the right side view, so it is omitted.
