Description

솔레노이드밸브{SOLENOID VALVE}Solenoid Valve {SOLENOID VALVE}

본 발명은 솔레노이드밸브에 관한 것으로, 더욱 상세하게는 솔레노이드의 여자(勵磁)여부에 따라 선택적으로 좌우이동되는 플런저의 우측단면에 다수의 그루브가 동심원을 이루면서 형성되는 솔레노이드밸브에 관한 것이다.The present invention relates to a solenoid valve, and more particularly, to a solenoid valve formed by forming a plurality of grooves concentrically on the right end surface of the plunger which is selectively moved left and right according to the excitation of the solenoid.

일반적으로, 솔레노이드밸브는 전원이 인가되는 솔레노이드(전자석)의 자력을 이용하여 플런저(Plunger)를 선택적으로 이동시킴으로써 유체(기름 또는 공기)의 흐름을 전환하는 방향전환밸브, 공작기계나 일반기계의 유압 또는 공기압 제어에 이용된다.In general, the solenoid valve is a directional valve for switching the flow of fluid (oil or air) by selectively moving the plunger by using the magnetic force of the solenoid (electromagnet) that is powered, the hydraulic pressure of a machine tool or a general machine Or air pressure control.

또한, 솔레노이드밸브는 전기스위치와 조합하여 원격조작을 할 수 있고, 회로를 무부하로 한다든지 시퀀스작용을 자동적으로 할 수 있다.In addition, the solenoid valve can be remotely operated in combination with an electric switch, and the circuit can be automatically loaded or sequenced automatically.

한편, 종래의 솔레노이드밸브는 도1에 도시한 바와같이 솔레노이드(2)에 전원이 인가되지 않는 경우 유체통로(8)를 통해 유입되는 유압과 스프링(9)의 탄성력에 의해 플런저(4)가 밸브몸체(5)측으로 이동되어 패킹(10)이 입구포트(6)의 출구측을 닫게 된다.Meanwhile, in the conventional solenoid valve, as shown in FIG. 1, when power is not applied to the solenoid 2, the plunger 4 is closed by the hydraulic pressure flowing through the fluid passage 8 and the elastic force of the spring 9. The packing 10 moves to the body 5 side to close the outlet side of the inlet port 6.

그리고, 전원이 인가되면서 솔레노이드(2)가 여자되면 플런저(4)가 고정자(3)측으로 이동되고, 이로써 패킹(10)에 의해 닫혀 있던 입구포트(6)가 열리면서 유체가 출구포트(7)로 유출된다.Then, when the solenoid 2 is energized while the power is applied, the plunger 4 is moved to the stator 3 side, thereby opening the inlet port 6 which is closed by the packing 10 and the fluid to the outlet port 7. Spills.

이때, 플런저(4)는 그 우측단면이 단순히 평면을 이루고 있어 유체통로(8)를 통해 유출되는 유체에 대한 흡입력이 떨어지고, 이에 따라 유압에 대한 응답성도 자연히 저하된다.At this time, the right end surface of the plunger 4 simply forms a flat surface, so that the suction force for the fluid flowing out through the fluid passage 8 is reduced, thereby naturally reducing the responsiveness to the hydraulic pressure.

결국, 종래의 솔레노이드밸브는 유체통로(8)를 통해 유출되는 유체에 대한 흡입력 및 응답성의 저하로 플런저(4)의 복귀이동이 감속되어 작동속도가 느린 문제점이 있다.As a result, the conventional solenoid valve has a problem in that the return movement of the plunger 4 is decelerated due to a decrease in suction force and responsiveness to the fluid flowing out through the fluid passage 8, resulting in a slow operation speed.

본 발명은 솔레노이드의 여자(勵磁)여부에 따라 선택적으로 좌우이동되는 플런저의 우측단면에 다수의 그루브가 동심원을 이루면서 형성되어 고정자측의 유체통로로부터 유입되는 유체에 대한 흡입력 및 응답성을 향상시킴으로써 플런저의 이동속도를 배가시킨 솔레노이드밸브를 제공함에 그 목적이 있다.The present invention is formed by forming a plurality of grooves concentrically on the right end surface of the plunger that is selectively moved left and right according to the excitation of the solenoid to improve the suction force and response to the fluid flowing from the fluid passage on the stator side It is an object of the present invention to provide a solenoid valve which doubles the moving speed of the plunger.

상기한 목적을 달성하기 위하여 본 발명은 솔레노이드의 여자와 스프링에 의해 플런저가 좌우이동되면서 상기 플런저의 양단면에 설치된 패킹이 각각 입구포트와 유체통로를 개폐하도록 구성되는 솔레노이드밸브에 있어서, 패킹을 이용하여 상기 유체통로를 개폐하는 상기 플런저의 우측단면에 다수의 그루브가 동심원을 이루도록 형성되는 것을 특징으로 하는 솔레노이드밸브를 제공하게 된다.In order to achieve the above object, the present invention provides a solenoid valve in which a packing installed at both ends of the plunger opens and closes an inlet port and a fluid passage while the plunger is moved left and right by an excitation and a spring of the solenoid. It is to provide a solenoid valve characterized in that a plurality of grooves are formed in a concentric circle on the right end surface of the plunger for opening and closing the fluid passage.

도면을 참조하여 본 발명을 설명한다.The present invention will be described with reference to the drawings.

도2 및 도3은 본 발명에 따른 솔레노이드밸브를 나타내는 구성도이다.2 and 3 is a block diagram showing a solenoid valve according to the present invention.

본 발명에 따른 플런저(4)에는 고정자(3)측의 유체통로(8)를 개폐하는 그 우측단면에 다수의 그루브(Groove)(16)가 동심원을 이루도록 형성되어 있다.In the plunger 4 according to the present invention, a plurality of grooves 16 are formed to form concentric circles on the right end surface of the plunger 4 to open and close the fluid passage 8 on the stator 3 side.

따라서, 본 발명에 따른 플런저(4)의 우측단면은 그 단면적에 있어 다수의 그루브(Groove)(16)에 의해 종래 플런저의 우측단면에 비해 상대적으로 크게 된다.Accordingly, the right end face of the plunger 4 according to the present invention is relatively large in cross-sectional area compared to the right end face of the conventional plunger by a plurality of grooves 16.

이로 인해, 본 발명에 따른 플런저(4)의 우측단면은 유체통로(8)로부터 유출되는 유체와의 접촉면적이 종래 플런저의 우측단면에 비해 상대적으로 크게 되고, 결국 그루브(16)를 형성하고 있는 플런저의 우측단면이 유압에 대한 흡인력과 응답성이 현저히 향상된다.For this reason, the right end surface of the plunger 4 according to the present invention has a relatively large contact area with the fluid flowing out of the fluid passage 8 compared with the right end surface of the conventional plunger, and eventually forms the groove 16. The right end surface of the plunger significantly improves the suction force and response to the hydraulic pressure.

더욱 상세히 설명하면, 솔레노이드(2)에 전원이 인가되는 경우 플런저(4)가 고정자(3)측으로 당겨지면서 이동하게 되는데, 이때 개방된 입구포트(6)로부터 유체가 유입된 후, 다시 출구포트(7)로 유출된다.In more detail, when power is applied to the solenoid 2, the plunger 4 is moved while being pulled toward the stator 3, where fluid is introduced from the open inlet port 6, and then the outlet port ( 7) outflow.

반대로, 플런저(4)의 패킹(11)이 유체통로(8)를 막고 있는 상태에서 전원이 차단되면 솔레노이드(2)의 여자가 제거되면서 플런저는 스프링(9)의 압축탄성력에의해 밸브몸체(5)로 이동하게 된다.On the contrary, if the power supply is cut off while the packing 11 of the plunger 4 is blocking the fluid passage 8, the excitation of the solenoid 2 is removed and the plunger is operated by the compression elastic force of the spring 9 so that the valve body 5 Will be moved to).

이때, 플런저(4)의 이동으로 유체통로(8)가 개방되면서 유입되는 유체가 플런저의 우측단면에 접촉하게 되는데, 플런저의 우측단면의 경우 다수의 그루브(16)가 형성되어 있어 유체통로(8)로부터 유출되는 유체와 보다 넓은 면적으로 접촉하게 된다.At this time, the fluid flowing in (8) is opened by the movement of the plunger 4 is in contact with the right end surface of the plunger, in the case of the right end surface of the plunger is formed with a plurality of grooves (16) fluid passage (8) In contact with the fluid flowing from the larger area.

이로써, 유체통로(8)로부터 유출되는 유체는 플런저(4)의 우측단면을 보다 큰힘으로 밀게 되고, 플런저(4)는 그 힘에 의해 더욱 빠른 속도로 밸브몸체(5)로 이동되어 패킹(10)을 이용하여 입구포트(6)를 닫게 된다.As a result, the fluid flowing out of the fluid passage 8 pushes the right end surface of the plunger 4 with a larger force, and the plunger 4 is moved to the valve body 5 at a higher speed by the force, thereby packing 10 ) To close the inlet port (6).

결국, 본 발명에 따른 솔레노이드밸브는 플런저(4)의 빠른 이동속도에 의해 출구포트(7)로 유출되는 유체의 양을 정확하게 제어할 수 있게 된다.As a result, the solenoid valve according to the present invention can accurately control the amount of fluid flowing out of the outlet port 7 by the fast moving speed of the plunger (4).

본 발명은 플런저의 우측단면에 동심원의 그루브를 형성시켜 유체와의 접촉면적을 증가시킴으로써 유체에 대한 흡입력 및 응답성을 향상시키고, 이로써 유체의 흐름을 보다 원활히 할 수 있는 효과를 제공하게 된다.The present invention improves the suction force and responsiveness to the fluid by forming a concentric groove in the right end surface of the plunger to increase the contact area with the fluid, thereby providing an effect that can smoothly flow the fluid.
