Description
본 고안은 유압의 유입과 배출의 방향성을 갖는 유압제어용 스풀밸브에 관한 것으로서, 보다 상세하게는 밸브스풀 일측의 슬리이브 이동을 지지하는 슬리이브에 형성된 포트와 밸브바디에 형성된 포트를 항상 일치시키는 유압제어용 스풀밸브에 관한 것이다.The present invention relates to a hydraulic control spool valve having a direction of inflow and outflow of hydraulic pressure, and more particularly, a hydraulic pressure that always matches a port formed in a sleeve and a port formed in a valve body supporting a sleeve movement of one side of the valve spool. The present invention relates to a control spool valve.
유압제어용 스풀밸브는 유압을 유입 및 배출시키도록 형성된 유입 및 배출포트에 형상에 따라 애뉼러 포트 스풀밸브와 파샬 스풀밸브로 구분된다.Hydraulic control spool valve is divided into an annular port spool valve and a partial spool valve according to the shape of the inlet and outlet ports formed to inflow and discharge the hydraulic pressure.
애뉼러 포트 스풀밸브는 상기 포트들을 좌우 대칭으로 형성하고 있으나, 파샬 포트 스풀밸브는 상기 포트들을 밸브바디의 일측에만 형성하고 있다.The annular port spool valve forms the ports symmetrically, but the partial port spool valve forms the ports only on one side of the valve body.
이러한 파샬 포트 스풀밸브는 복수의 포트로 유압의 흡입 배출을 가능케 하는 랜드를 구비한 밸브스풀을 구비하고 있으며, 이 밸브스풀의 일측에 유압의 유입배출을 제어하는 포트를 형성한 슬리이브를 개재하여 밸브바디에 결합되기도 한다.Such a partial port spool valve includes a valve spool having a land for allowing suction and discharge of hydraulic pressure to a plurality of ports, and through a sleeve having a port for controlling hydraulic inflow and discharge on one side of the valve spool. It can also be coupled to a valve body.
그러나 상기와 같은 유압제어용 스풀밸브는 밸브바디의 일측에만 형성된 유입 및 배출포트로 유압을 유입 및 배출시키기 때문에 이 유압이 밸브스풀과 슬리이브를 내장한 밸브바디 내에서 회전력을 발생시켜 슬리이브를 회전시키므로 슬리이브에 형성된 홀과 밸브바디에 형성된 홀을 불일치시켜 밸브의 오작동을 유발시킬 우려가 있다.However, the hydraulic control spool valve as described above induces and discharges hydraulic pressure to the inlet and outlet ports formed on only one side of the valve body, so the hydraulic pressure generates a rotational force in the valve body incorporating the valve spool and the sleeve to rotate the sleeve. Therefore, the holes formed in the sleeve and the holes formed in the valve body may be inconsistent, causing a malfunction of the valve.
따라서 본 고안은 상기와 같은 우려를 해소하기 위하여 안출된 것으로서, 본 고안의 목적은 밸브바디에 내장되는 슬리이브의 회전을 방지시켜 슬리이브에 형성된 홀과 밸브바디에 형성된 홀을 항상 일치시켜 밸브의 오작동을 방지하는 유압제어용 스풀밸브를 제공하는데 있다.Therefore, the present invention is devised to solve the above concerns, the object of the present invention is to prevent the rotation of the sleeve built in the valve body to always match the hole formed in the sleeve and the hole formed in the valve body of the valve To provide a hydraulic control spool valve to prevent malfunction.
이를 실현하기 위하여 본 고안에 따른 유압제어용 스풀밸브는 유압의 유입 및 배출이 일측으로만 가능하도록 복수개의 흡,배출 포트를 형성한 밸브바디, 이 밸브바디에 내장되어 상기 흡,배출 포트로 유입 및 배출되는 유압을 제어하도록 복수의 랜드를 형성한 밸브스풀, 이 밸브스풀이 축방향으로 슬리이브 이동 가능하도록 밸브스풀의 일측에 흡,배출 포트를 형성하여 제공되는 슬리이브, 이 슬리이브에 형성된 흡배출 포트와 밸브바디에 형성된 흡배출 포트를 일치시키도록 슬리이브와 밸브바디사이에 제공되어 슬리이브가 흡,배출 포트로 유입 및 배출되는 유압에 의하여 발생되는 회전력에 저항하여 슬리이브의 회전을 방지시키는 회전방지수단, 이 회전방지수단이 슬리이브와 밸브바디사이에 고정되도록 밸브바디의 일측에 체결부재로 장착되는 앤드 커버를 포함한다.In order to realize this, the spool valve for hydraulic control according to the present invention has a valve body having a plurality of suction and discharge ports so that the inflow and discharge of hydraulic pressure is possible on only one side, and the valve body is built in the intake and discharge port. A valve spool having a plurality of lands formed to control discharged hydraulic pressure, a sleeve provided by forming suction and discharge ports on one side of the valve spool so that the valve spool can move in the axial direction, and a suction formed in the sleeve Provided between the sleeve and the valve body to match the discharge port and the suction port formed in the valve body to prevent rotation of the sleeve by resisting the rotational force generated by the hydraulic pressure flowing into and out of the suction port Anti-rotation means, the anti-rotation means being mounted as a fastening member on one side of the valve body to be fixed between the sleeve and the valve body And an end cover.
상술한 바와 같이 구성되는 유압제어용 스풀밸브는 슬리이브와 밸브바디사이에 회전방지수단을 개재하여 흡,배출 포트로 공급및 배출되는 유압에 의하여 발생되는 회전력에도 불구하고 슬리이브가 회전되는 것을 방지한다.The hydraulic control spool valve configured as described above prevents the sleeve from rotating despite the rotational force generated by the hydraulic pressure supplied and discharged to the suction and discharge ports through the rotation preventing means between the sleeve and the valve body. .

도 1은 본 고안에 관련하는 유압제어용 스풀밸브의 측면도로서, 밸브바디(1)의 일측에 앤드 커버(3)를 체결부재(5)로 체결하는 구조를 이루고 있다.1 is a side view of a hydraulic control spool valve according to the present invention, and has a structure in which the end cover 3 is fastened to a fastening member 5 on one side of the valve body 1.
즉, 밸브바디(1)는 도2에 도시된 바와 같이 유압을 일측으로 공급받고, 공급받은 측으로 유압을 배출할 수 있는 구조로 이루어져 있다.That is, the valve body 1 is configured to receive the hydraulic pressure to one side, as shown in Figure 2, and to discharge the hydraulic pressure to the supplied side.
따라서, 밸브바디(1)의 일측에 흡,배출 포트(7)를 형성하고, 이 포트(7)들로 유압의 유입 및 배출이 가능하도록 복수의 랜드(9)를 갖는 밸브스풀(11)이 이의 축방향 슬리이브 이동을 가능케 하도록 밸브바디(1)에 내장되어 있다.Therefore, a valve spool 11 having a plurality of lands 9 is formed on one side of the valve body 1 so as to allow suction and discharge ports 7 to flow into and out of the ports 7. It is embedded in the valve body 1 to enable its axial sleeve movement.
그리고 상기 밸브스풀(11)의 일측에는 밸브스풀(11)의 축방향 이동을 안내하는 슬리이브(13)가 개재되어 있다.And one side of the valve spool 11 is provided with a sleeve 13 for guiding the axial movement of the valve spool 11.
이 슬리이브(13)에는 밸브바디(1)에 형성된 흡,배출 포트(7) 중 한 포트(7')와 연통되어 밸브스풀(11)을 형성하는 랜드(9) 중 한 랜드(9')에 작용하는 유압의 흡,배출 포트를 제어하는 포트(15)가 형성되어 있다.One of the lands 9 'of the lands 9, which communicates with one of the intake and discharge ports 7' formed on the valve body 1 and forms a valve spool 11, is formed in the sleeve 13. The port 15 which controls the suction and discharge port of the hydraulic pressure acting on the is provided.
또 이 슬리이브(13)와 밸브바디(1) 사이에는 상기 흡,배출 포트(7)로 공급 및 배출되는 유압에 의하여 발생되는 회전력에 의한 슬리이브(13)의 회전을 방지하도록 회전방지수단으로 제1,2홈(17,19)가 스톱퍼(21)를 형성 및 제공하고 있다.In addition, the sleeve 13 and the valve body (1) between the rotation preventing means to prevent the rotation of the sleeve 13 by the rotational force generated by the hydraulic pressure supplied and discharged to the suction and discharge port (7) The first and second grooves 17 and 19 form and provide the stopper 21.
즉, 상기 제1홈(17)은 도3에 도시된 바와 같이, 슬리이브(13)의 일측에 형성되고, 제2홈(19)은 상기 제1홈(17)의 대향측 밸브바디(1)에 형성되어 있다.That is, the first groove 17 is formed on one side of the sleeve 13, as shown in Figure 3, the second groove 19 is the valve body 1 of the opposite side of the first groove 17 ) Is formed.
그리고 스톱퍼(21)는 상기 제1,2홈(17,19)에 결합되어 슬리이브(13)의 회전을 방지하도록 체결부재(5)에 의하여 밸브바디(1)에 결합되는 앤드 커버(3)에 의하여 고정되는 구조를 이루고 있다.And the stopper 21 is coupled to the first and second grooves (17, 19) end cover (3) coupled to the valve body (1) by a fastening member (5) to prevent rotation of the sleeve (13) It is a structure that is fixed by.
상술한 바와 같이 구성된 유압제어용 스풀밸브는 밸브스풀(11)에 형성된 랜드(9)들에 의하여 형성되는 유로를 통하여 흡,배출 포트(7)로 유압을 흡입 및 배출시킨다.The hydraulic control spool valve configured as described above sucks and discharges hydraulic pressure to the suction and discharge ports 7 through a flow path formed by the lands 9 formed in the valve spool 11.
상기와 같이 흡입 및 배출되는 유압은 밸브스풀(11)에 회전력을 발생시키며, 밸브바디(1)에 형성된 포트(7)를 통하여 슬리이브(13)에 형성된 포트(15)로 공급되어 랜드(9')에 작용하는 유압과 이에 작용한 후 배출되는 유압은 슬리이브(13)에 회전력을 발생시킨다.The hydraulic pressure sucked and discharged as described above generates a rotational force in the valve spool 11, is supplied to the port 15 formed in the sleeve 13 through the port 7 formed in the valve body 1, and thus the land 9. The hydraulic pressure acting on ') and the hydraulic pressure discharged after acting on the hydraulic force generate rotational force on the sleeve 13.
이때 슬리이브(13)에 작용하는 회전력은 제1,2홈(17,19)에 결합되는 스톱퍼(21)에 의하여 밸브바디(1)로 전달 소멸된다. 따라서 밸브바디(1)에 형성된 포트(7')와 슬라이브(13)에 형성된 포트(15)는 항상 일치하게 된다.At this time, the rotational force acting on the sleeve 13 is transferred to the valve body 1 by the stopper 21 coupled to the first and second grooves 17 and 19. Therefore, the port 7 'formed in the valve body 1 and the port 15 formed in the slave 13 are always coincident with each other.
상술한 바와 같이 본 고안에 따른 유압제어용 스풀밸브는 스풀밸브와 밸브바디사이에 회전방지수단을 개재하여 흡,배출 포트로 공급 및 배출되는 유압에 의하여 발생되는 회전력에도 불구하고 슬리이브가 회전되는 것을 방지하여 슬리이브에 형성된 홀과 밸브바디에 형성된 홀을 일치시켜 밸브의 오작동을 방지할 수 있다.As described above, in the hydraulic control spool valve according to the present invention, the sleeve is rotated in spite of the rotational force generated by the hydraulic pressure supplied and discharged to the suction and discharge ports through the rotation prevention means between the spool valve and the valve body. By preventing the holes formed in the sleeve and the holes formed in the valve body to match the malfunction of the valve can be prevented.
