도 1은 본 고안에 따른 양방향 공기주입식 스풀밸브를 나타낸 측단면도이고, 도 2는 본 고안에 따른 양방향 공기주입식 스풀밸브의 작동상태를 나타낸 측단면도이다.1 is a side cross-sectional view showing a bi-directional air injection spool valve according to the present invention, Figure 2 is a side sectional view showing an operating state of the bi-directional air injection spool valve according to the present invention.
본 고안에 따른 양방향 공기주입식 스풀밸브는, 일측에 유입유로(11)가 형성되고, 타측에 배출유로(12)가 형성되며, 상기 유입유로(11)와 배출유로(12)를 가로질러 스풀홀(13)이 형성되고, 상기 스풀홀(13)의 일측벽을 관통하여 제1공기출입구(14)가 형성되며, 상기 스풀홀(13)의 측벽에 상기 제1공기출입구(14)의 반대편으로 제2공기출입구(15)가 형성된 밸브몸체(10)와, 상기 밸브몸체(10)의 스풀홀(13)에 축방향으로 슬라이드이동가능하게 삽입되고, 내부에 축방향을 따라 연통홀(21)이 형성되며, 상기 연통홀(21)의 측벽을 관통하여 축방향을 따라 소정간격을 두고 복수개의 관통홀(22)이 형성된 스풀(20)을 포함하고 있다.In the bidirectional air injection type spool valve according to the present invention, the inflow passage 11 is formed on one side, the discharge passage 12 is formed on the other side, the spool hole across the inflow passage 11 and the discharge passage 12 13 is formed, and the first air inlet 14 is formed through one side wall of the spool hole 13, and is opposite to the first air inlet 14 on the sidewall of the spool hole 13. The valve body 10 having the second air inlet 15 is inserted into the valve body 10 and the spool hole 13 of the valve body 10 so as to be movable in the axial direction, and the communication hole 21 therein along the axial direction. The spool 20 includes a spool 20 having a plurality of through-holes 22 formed at predetermined intervals in the axial direction through the sidewalls of the communication hole 21.
상기 밸브몸체(10)는 일측에 유입유로(11)가 형성되고, 그 유입유로(11)와 소정간격을 두고 배출유로(12)가 형성되며, 상기 유입유로(11)와 배출유로(12)를 가로질러 스풀홀(13)이 형성되고, 상기 스풀홀(13)의 일측벽을 관통하여 제1공기출입구(14)가 형성되며, 상기 스풀홀(13)의 측벽에 상기 제1공기출입구(14)의 반대편으로 제2공기출입구(15)가 형성되어 있다.The valve body 10 has an inflow passage 11 formed at one side thereof, and a discharge passage 12 is formed at a predetermined interval with the inflow passage 11, and the inflow passage 11 and the discharge passage 12 are formed. A spool hole 13 is formed across the through hole, and a first air entrance 14 is formed through one side wall of the spool hole 13, and the first air entrance hole is formed on a sidewall of the spool hole 13. On the other side of 14), the second air entrance 15 is formed.
상기 유입유로(11)와 배출유로(12)는 스풀홀(13)을 사이에 두고 서로 반대편에 형성되되, 스풀(20)의 이동방향을 따라 소정간격을 두고 엇갈리게 형성되어 있다.The inflow passage 11 and the discharge passage 12 are formed on opposite sides with the spool hole 13 interposed therebetween, and are alternately formed at predetermined intervals along the moving direction of the spool 20.
상기 스풀홀(13)은 상기 유입유로(11)와 배출유로(12)를 가로지르는 방향으로 형성되어 스풀(20)을 안내하게 된다.The spool hole 13 is formed in a direction crossing the inflow passage 11 and the discharge passage 12 to guide the spool 20.
상기 스풀(20)은 상기 스풀홀(13)을 따라 슬라이드이동가능하게 삽입설치되고, 내부에 축방향을 따라 연통홀(21)이 형성되어 있으며, 그 연통홀(21)의 측벽에 2열의 관통홀(22)이 축방향을 따라 소정간격을 두고 형성되되 각 열은 원주방향을 따라 소정간격을 두고 다수개가 형성되어 있다.The spool 20 is slidably inserted along the spool hole 13 and has a communication hole 21 formed therein along the axial direction, and penetrates two rows through the side wall of the communication hole 21. Holes 22 are formed at predetermined intervals along the axial direction, and each column is formed in a plurality at predetermined intervals along the circumferential direction.
따라서, 상기 스풀(20)의 이동에 따라 2열의 관통홀(22)이 유입유로(11)와 배출유로(12)에 각각 대향되게 위치하게 되면 유입유로(11)와 배출유로(12)가 연통되게 되고, 2열의 관통홀(22) 중 1열만이 유입유로(11)나 배출유로(12)에 대향하게 되면 유입유로(11)에서 배출유로(12)로의 통로가 차단된다.Therefore, when the two through-holes 22 are positioned to face the inflow passage 11 and the discharge passage 12 as the spool 20 moves, the inflow passage 11 and the discharge passage 12 communicate with each other. When only one row of the two rows of through holes 22 faces the inflow passage 11 or the discharge passage 12, the passage from the inflow passage 11 to the discharge passage 12 is blocked.
상기 스풀(20)은 스풀홀(13)을 따라 슬라이드이동하면서 상기 유입유로(11)와 배출유로(12)를 선택적으로 연통시켜 유체의 통로를 개폐하게 되고, 양단으로 공급되는 공기에 의해 슬라이드이동하게 된다.The spool 20 slides along the spool hole 13 to selectively communicate the inflow passage 11 and the discharge passage 12 to open and close the passage of the fluid, and the slide movement by the air supplied to both ends. Done.
상기 제1공기출입구(14)는 상기 스풀홀(13)의 일측벽을 관통하여 형성되되, 상기 스풀(20)의 축방향을 따라 스풀(20) 상부에 형성되어 스풀(20)의 상부로 공기를 주입시키게 된다.The first air inlet 14 is formed through one side wall of the spool hole 13, and is formed on the spool 20 along the axial direction of the spool 20 so that the air above the spool 20 is formed. Will be injected.
상기 제2공기출입구(15)는 상기 스풀홀(13)의 일측벽을 관통하여 형성되되, 상기 스풀(20)의 축방향을 따라 스풀(20)의 하부에 형성되어 스풀(20)의 하부로 공기를 주입시키게 된다.The second air entrance 15 is formed through one side wall of the spool hole 13, and is formed below the spool 20 along the axial direction of the spool 20 to the bottom of the spool 20. Air is injected.
상기 제1공기출입구(14)로 공기가 주입되면 스풀(20)은 제2공기출입구(15) 쪽으로 이동하게 되고, 이때 제2공기출입구(15)는 개방되어 스풀홀(13)의 공기를 배출시킴으로써 스풀(20)을 신속하게 이동시킬 수 있게 된다.When air is injected into the first air inlet 14, the spool 20 moves toward the second air inlet 15. At this time, the second air inlet 15 is opened to discharge air from the spool hole 13. By doing so, the spool 20 can be moved quickly.
상기 제2공기출입구(15)로 공기가 주입되면 제1공기출입구(14)가 개방되어 스풀(20)이 제1공기출입구(14) 쪽으로 신속하게 이동시키게 된다.When air is injected into the second air inlet 15, the first air inlet 14 is opened to quickly move the spool 20 toward the first air inlet 14.
상기 제1공기출입구(14)와 제2공기출입구(15)로 공기를 출입시킴으로써 다른 유체에 비해 출입속도가 크므로 스풀(20)을 신속하게 이동시킬 수 있게 된다.By entering air into the first air inlet 14 and the second air inlet 15, the spool 20 can be moved quickly because the inlet speed is larger than other fluids.
한편, 상기 제1공기출입구(14)로 공기가 주입될 때 제2공기출입구(15)로 공기를 강제흡입하여 배출시키거나 제2공기출입구(15)로 공기가 주입될 때 제1공기출입구(14)로 공기를 강제흡입하여 배출시킴으로써, 반대쪽에서 주입되는 공기압에 의해 강제로 배출되는 공기의 출입속도보다 공기를 더 신속하게 출입시켜 스풀(20)을 더욱 신속하게 이동시키는 것도 가능하게 된다.Meanwhile, when air is injected into the first air inlet 14, the air is forced into the second air inlet 15 to be discharged, or when air is injected into the second air inlet 15, the first air inlet ( By forcibly inhaling and discharging the air to 14), it is also possible to move the spool 20 more quickly by entering and exiting the air more quickly than the entrance and exit speed of the air forcedly discharged by the air pressure injected from the opposite side.
이상에서 설명한 바와 같이 본 고안에 따른 양방향 공기주입식 스풀밸브에 의하면, 스풀의 양단으로 공기를 신속하게 출입시켜 스풀을 신속하게 이동시킴으로써 유로를 신속하게 개폐할 수 있는 효과가 있다.As described above, according to the bidirectional air injection type spool valve according to the present invention, the air can be opened and closed quickly by moving air in and out quickly at both ends of the spool.
