The 175 exits and the gas then enters each of the second plenums 502 from the ID hole 53 of the cylinder 50. According to the difference between the gas input pressure of the first portion and the second portion of the gas input pressure, the moving direction of the actuating member 54 after the force is changed.
參閱圖10、圖11並搭配圖5、圖6及圖18，當該氣源60未進氣時，該閥結構部10沒有氣體供給該閥門***70，同時該切換部20未通入氣體；此時，該滑槽11內的該活塞軸12未受氣體抵壓，因此該彈性件123提供復歸的彈力，該活塞軸12向上移動，使該通氣凹部122位於該入氣孔176的側邊，供該入氣孔176與該閥結構部10形成連通狀態；而該閥門***70未供氣，該梭動閥30的該輸入氣孔32未進氣，氣體由該氣缸50的該等儲氣室503提供，氣體流經該氣室儲氣孔173進入該閥結構部10，由於該氣室儲氣孔173與該排氣孔1731連通，因此氣體流入該排氣孔1731後，進入連通的該滑槽11內，再依序通過該第二通管42、該第二輸氣孔34、該T形通道31、該第一輸氣孔33、該第一通管41，氣體通過該第二通氣槽14流入該第二氣室孔174，達到氣體推動該等作動件54復歸至預設 位置。 Referring to FIG. 10, FIG. 11 and FIG. 5, FIG. 6 and FIG. 18, when the air source 60 is not in intake, the valve structure portion 10 has no gas supplied to the valve positioner 70, and the switching portion 20 does not pass the gas. At this time, the piston shaft 12 in the chute 11 is not pressed by the gas, so the elastic member 123 provides a returning elastic force, and the piston shaft 12 moves upward, so that the ventilation recess 122 is located at the side of the air inlet hole 176. The air inlet hole 176 is in communication with the valve structure portion 10; and the valve positioner 70 is not supplied with air, the input air hole 32 of the shuttle valve 30 is not aired, and the gas is stored by the air cylinder 50. The chamber 503 provides that the gas flows into the valve structure portion 10 through the gas storage hole 173. Since the gas storage hole 173 communicates with the exhaust hole 1731, the gas flows into the exhaust hole 1731 and enters the sliding of the communication. In the slot 11, the second through pipe 42, the second air transfer hole 34, the T-shaped passage 31, the first air transfer hole 33, and the first through pipe 41 are sequentially passed through the second ventilation. The groove 14 flows into the second plenum hole 174, and the gas is pushed to return the actuating member 54 to the preset. position.
參閱圖14並搭配圖7、圖8，氣體從該氣源60的該進氣孔171輸入，接著氣體分成兩部分，一部分氣體流經該第一管路15及另一部分氣體流經該第二管路16。流經該第二管路16的氣體，會順著該氣室儲氣孔173通過該IB孔位51，接著氣體便儲存至該等儲氣室503。流經該第一管路15的氣體同樣會分成兩部分，一部分的氣體流入至該切換部20，另一部分的氣體則會通過該出氣孔172離開該閥結構部10，並進入該閥門***70，該閥門***70具有調控氣體比例及輸氣壓力的功效，可根據使用者需求進行切換，在此實施例中，該閥門***70輸出至該第一通氣槽13的氣體壓力較大，氣體經由該第一氣室孔174通過該氣缸50的該IC孔位52，進入該第一容氣室501內；而該閥門***70輸出另一部分較小氣體至該第二通氣槽14，氣體接著經由該第二氣室孔175通過該氣缸50的該ID孔位53，進入該等第二容氣室502內，由於該第一容氣室501的氣體壓力多於該等第二容氣室502的氣體壓力，因此該第一容氣室501的氣壓推動該等作動件54朝向各該第二容氣室502的方向移動，同時，由於各該第二容氣室502內部具有氣體，因此可以避免該等作動件54移動速度過快而撞擊至該氣缸50的內壁。 Referring to FIG. 14 and in conjunction with FIG. 7 and FIG. 8, gas is input from the air inlet hole 171 of the gas source 60, and then the gas is divided into two parts, and a part of the gas flows through the first line 15 and another part of the gas flows through the second part. Line 16. The gas flowing through the second line 16 passes through the chamber vent 173 through the IB hole 51, and the gas is then stored in the plenum 503. The gas flowing through the first line 15 is also divided into two parts, a part of the gas flows into the switching part 20, and another part of the gas leaves the valve structure 10 through the air outlet 172 and enters the valve positioner. 70, the valve positioner 70 has the function of regulating the gas ratio and the gas transmission pressure, and can be switched according to the user's demand. In this embodiment, the gas pressure of the valve positioner 70 outputted to the first ventilation groove 13 is relatively large. The gas passes through the first plenum hole 174 through the IC hole 52 of the cylinder 50 into the first plenum 501; and the valve locator 70 outputs another portion of the smaller gas to the second vent 14 The gas then passes through the second plenum hole 175 through the ID hole 53 of the cylinder 50 into the second plenum 502, because the gas pressure of the first plenum 501 is greater than the second The gas pressure of the plenum 502, so that the air pressure of the first plenum 501 pushes the actuators 54 toward each of the second plenums 502, and at the same time, since each of the second plenums 502 has Gas, thus avoiding the movement of the actuators 54 The moving speed is too fast to hit the inner wall of the cylinder 50.
參閱圖15並搭配圖7、圖8，圖15與圖14差異僅在於該閥門***70的供氣比例不同，流入至該第一通氣槽13的進氣壓力較小，使得該第一容氣室501的氣體壓力小；流入至該第二通氣槽14的進氣壓力大，使得該第二容氣室502的氣體壓力大，進而控制該等作 動件54相向移動，同時，位於該第一容氣室501的氣體能降低該等作動件54相向靠近的速度過快而撞到該氣缸50內壁可能。 Referring to FIG. 15 and FIG. 7 and FIG. 8, FIG. 15 differs from FIG. 14 only in that the air supply ratio of the valve positioner 70 is different, and the intake pressure flowing into the first ventilation groove 13 is small, so that the first capacity is The gas pressure of the gas chamber 501 is small; the inlet pressure flowing into the second venting tank 14 is large, so that the gas pressure of the second gas plenum 502 is large, thereby controlling the operation. The moving members 54 move toward each other, and at the same time, the gas located in the first air chamber 501 can lower the speed at which the actuators 54 are approaching too fast and hit the inner wall of the cylinder 50.
參閱圖16並搭配圖7、圖8，為該閥門***70完全從該第一通氣槽13進氣的示意圖。首先，氣體從該氣源60的該進氣孔171輸入，接著氣體分成兩部分，一部分氣體流經該第一管路15及另一部分氣體流經該第二管路16。流經該第二管路16的氣體，會順著該氣室儲氣孔173通過該IB孔位51，接著氣體便儲存至該等儲氣室503。流經該第一管路15的氣體同樣會分成兩部分，一部分的氣體流入至該切換部20，另一部分的氣體則會通過該出氣孔172離開該閥結構部10，並進入該閥門***70，該閥門***70調控氣體全部從該第一通氣槽13輸入，氣體經由該第一氣室孔174通過該氣缸50的該IC孔位52，進入該第一容氣室501內；該閥門***70在未輸入氣體至該第二通氣槽14的情況下，該等第二容氣室502並無氣體，因此該第一容氣室501的氣壓推動該等作動件54朝向各該第二容氣室502的方向移動。 Referring to FIG. 16 and FIG. 7 and FIG. 8, a schematic diagram of the valve positioner 70 fully inhaling from the first venting groove 13 is shown. First, gas is supplied from the intake port 171 of the gas source 60, and then the gas is divided into two portions, and a portion of the gas flows through the first line 15 and another portion of the gas flows through the second line 16. The gas flowing through the second line 16 passes through the chamber vent 173 through the IB hole 51, and the gas is then stored in the plenum 503. The gas flowing through the first line 15 is also divided into two parts, a part of the gas flows into the switching part 20, and another part of the gas leaves the valve structure 10 through the air outlet 172 and enters the valve positioner. 70, the valve positioner 70 regulates gas input from the first venting groove 13, and the gas passes through the first plenum hole 174 through the IC hole 52 of the cylinder 50 to enter the first plenum 501; In the case where the valve locator 70 does not input gas to the second venting groove 14, the second plenum 502 has no gas, so the air pressure of the first plenum 501 pushes the actuating members 54 toward the respective ones. The direction of the second air chamber 502 moves.

The structural portion 10 is connected to the exhaust gas due to the gas storage hole 173 The hole 1731, so that the gas returns to the first line 15 along the vent hole 1731, and the gas exits the valve structure portion 10 from the air outlet hole 172 into the valve positioner 70, and the valve positioner 70 is controlled to pass the gas. Going to the second venting groove 14 and exiting the valve structure portion 10 from the second plenum hole 175, entering the second plenum chamber 502 via the ID hole 53 and pushing the actuators 54 toward each other through the gas Closely, the safety of the cylinder 50 is achieved; and the opposing actuators 54 push the gas located in the first air chamber 501 to pass the gas through the IC hole 52 into the first air chamber hole 174. The gas exits the valve structure portion 10 from the first venting groove 13 to the valve positioner 70, and the gas is discharged through the valve positioner 70.
參閱圖19並搭配圖12，於該氣源60提供氣體瞬間，該活塞軸12向下推抵該彈性件123，使該通氣凹部122與該入氣孔176形成通道；當該氣缸50安全復歸後，該等第二容氣室502的氣體會從該ID孔位53離開，並從該第二氣室孔175進入該閥結構部10的該第二通氣槽14，經由該第一通管41進入該梭動閥30，氣體通過該T形通道31並從該第二輸氣孔34離開，氣體接著通過該第二通管42，並通過該通氣凹部122與該入氣孔176形成的通道，再從該洩氣孔177排除氣體。 Referring to FIG. 19 and FIG. 12, when the gas source 60 supplies gas, the piston shaft 12 pushes down against the elastic member 123, so that the venting recess 122 forms a passage with the air inlet 176; when the cylinder 50 is safely returned The gas of the second gas containing chamber 502 will leave the ID hole 53 and enter the second venting groove 14 of the valve structure portion 10 from the second plenum hole 175 via the first through pipe 41. Entering the shuttle valve 30, the gas passes through the T-shaped passage 31 and exits from the second air delivery hole 34, and the gas then passes through the second communication tube 42 and passes through the passage formed by the ventilation recess 122 and the air inlet hole 176. The gas is removed from the vent hole 177.
