<負壓作動> <Negative pressure operation>
請參閱第8、9圖所示，供氣設備(圖中未示)與送氣機構200之T型管21進氣道212連接，傳遞供氣設備之高壓氣體，另將開關件23開啟以連通T型管21出氣道213與外部，讓高壓氣體由T型管21之進氣道212進入後，再經由出氣道213後由開關件23釋出，俾使T型管21之支氣道214形成一吸力。 Please refer to Figures 8 and 9. The gas supply equipment (not shown) is connected to the T-tube 21 inlet 212 of the air supply mechanism 200 to transfer the high-pressure gas of the gas supply equipment, and the switch 23 is opened to communicate. The T-tube 21 exits the air passage 213 and the outside. After the high-pressure gas enters through the inlet 212 of the T-tube 21, it is released by the switch 23 after passing through the air passage 213, so that the bronchus 214 of the T-tube 21 is formed. One suction.
此時桶件11容室112內部之氣體，經由連接座41 之側孔414進入，經連接座41之穿伸孔412、閥座32之閥孔321、閥件33之氣道334、及T型管21之支氣道214後由出氣道213離開，俾使桶件11之容室112壓力小於桶件11外部。透過閥座32之調節，俾使容室112之氣體可快速的被帶離容室112。 At this time, the gas inside the container 112 of the barrel 11 passes through the connecting seat 41 The side hole 414 enters, passes through the extension hole 412 of the connection seat 41, the valve hole 321 of the valve seat 32, the air passage 334 of the valve member 33, and the bronchus 214 of the T-shaped pipe 21, and then exits from the air passage 213. The pressure of the container 112 of the component 11 is lower than that of the outside of the barrel component 11. Through the adjustment of the valve seat 32, the gas in the chamber 112 can be quickly taken away from the chamber 112.
<正壓作動> <Positive pressure action>
請參閱第10、11圖所示，高壓氣體由T型管21之進氣道212進入，此時將開關件23關閉使T型管21之出氣道213不與外部連通，讓高壓氣體經由T型管21之支氣道214進入桶件11容室112。 Please refer to Figs. 10 and 11. High-pressure gas enters through the inlet 212 of the T-tube 21.

高壓氣體經由T型管21之支氣道214進入，經閥座32之閥孔321、閥件33之閥件孔331、及連接座41之側孔414後進入容室112，俾使桶件11之容室112壓力大於桶件11外部。 The high-pressure gas enters through the branch passage 214 of the T-tube 21, passes through the valve hole 321 of the valve seat 32, the valve member hole 331 of the valve member 33, and the side hole 414 of the connection seat 41, and then enters the chamber 112, so that the barrel member 11 The pressure in the chamber 112 is greater than the outside of the barrel 11.
透過閥座32之調節，俾以避免進入容室112之高壓氣體過大或過急，導致桶件11無法承受其壓力，致使桶件11受損的缺失。 Through the adjustment of the valve seat 32, the high-pressure gas entering the chamber 112 is prevented from being too large or too rapid, which causes the barrel 11 to be unable to withstand its pressure, which causes the barrel 11 to be damaged.
<防溢機構作動> <Operation of the overflow prevention mechanism>
請參閱第3、4、12圖所示，容室112內之液體(圖中未示)過多或桶件11傾倒時，液面會朝桶件11桶口114運動，並使浮球43牽引浮桿42向上運動，讓浮桿42頂端套設之防溢環片44頂抵閥座32朝下的端面，藉以封閉閥孔小徑段3214之 截面，避免液體經閥孔321溢出。 Please refer to Figures 3, 4, and 12. When there is too much liquid (not shown) in the chamber 112 or the bucket 11 is dumped, the liquid level will move toward the bucket mouth 114 of the bucket 11 and the float 43 will be pulled. The floating rod 42 moves upward, so that the overflow prevention ring piece 44 sleeved on the top of the floating rod 42 abuts the downwardly facing end surface of the valve seat 32, thereby closing the small diameter section 3214 of the valve hole. Section to prevent liquid from overflowing through valve hole 321.
