본 고안은 고압유의 유로를 전환하는데 사용하는 슬라이드 수풀밸브(SLIDE SPOOL VALVE)에 있어서, 유체의 유로개폐 및 전환작용을 수행하는 스풀을 개량하여 스풀의 이동방향으로 작용하는 압력을 극소화함으로써, 스풀이 원활하게 작동하도록 하기 위한 유압감소를 위한 슬라이드 스풀밸브용 스풀에 관한 것이다.The present invention, in the slide pool valve (SLIDE SPOOL VALVE) used to switch the flow path of the high pressure oil, by improving the spool to perform the opening and closing of the flow path of the fluid to minimize the pressure acting in the direction of movement of the spool, It relates to a spool for the slide spool valve for reducing the hydraulic pressure to operate smoothly.
슬라이드 밸브에 설치되어 유체의 유로를 개폐, 전환하는 작용을 하는 스풀은 통상적으로 제1도에 도시된 바와 같이, 외주면에 직각으로 요홈(2')이 형성된 스풀(1')을 사용하여 왔었다.The spool installed in the slide valve and acting to open and close the flow path of the fluid has generally used the spool 1 'having the groove 2' formed at right angles to the outer circumferential surface as shown in FIG.
그러나 상기한 종래의 스풀(1')은, 밸브본체의 실린더내를 슬라이딩할 때 유압실린더에서 공급되는 고압유의 압력을 스풀 외주면의 직각으로 형성된 요홈(2')의 벽면이 직접적으로 받게되어, 스풀에서의 유체 유동 작용이 원활하게 이루어지지 않게되는 문제점이 발생하게 되었다.However, in the conventional spool 1 ', the wall surface of the groove 2' formed at right angles to the outer circumference of the spool is directly received by the pressure of the high pressure oil supplied from the hydraulic cylinder when sliding the cylinder of the valve body. There is a problem that does not flow smoothly in the fluid flow action.
본 고안은 이러한 문제점을 해결하기 위하여 스풀의 외주면에 형성되는 요홈의 양벽면이 곡면을 이루도록 함으로써, 유압실린더에서 발생된 고압유의 압력을 효과적으로 분산시켜 스풀의 슬라이딩작용이 원활하게 이루어지도록 구성한 것으로, 이하 첨부도면에 의하여 상세히 설명하면 다음과 같다.In order to solve this problem, the present invention is configured so that both wall surfaces of the grooves formed on the outer circumferential surface of the spool form a curved surface, thereby effectively dispersing the pressure of the high pressure oil generated from the hydraulic cylinder, thereby smoothly sliding the spool. When described in detail by the accompanying drawings as follows.
밸브본체내의 실린더(4)를 수풀(1)이 왕복운동을 하면서 유로(5), (5a)를 개폐 또는 전환하는 통상의 슬라이드 뺄브에 있어서, 스풀(1)의 외주면에 직각방향으로 형성된 요홈(2)의 벽면(3)(3a)을 곡면으로 형성하여서 된 것이다.In the conventional slide pulley which opens and closes or switches the flow paths 5 and 5a while the bush 1 reciprocates the cylinder 4 in the valve body, grooves formed at right angles to the outer circumferential surface of the spool 1 The wall surface 3 (3a) of 2) was formed in the curved surface.
이와 같이 구성된 본 고안은, 유압실린더(도시되지 않음)에서 공급되는 고압유가 유로(5)로 유입되어 스풀(1)의 요홈(2)에 유입되므로 스풀(1)의 슬라이딩에 따라 스풀(1)의 외주면에 요설된 요홈(2)를 통하여 다른 유로(5a)로 유동되는 것이다.According to the present invention configured as described above, since the high pressure oil supplied from the hydraulic cylinder (not shown) flows into the flow path 5 and flows into the groove 2 of the spool 1, the spool 1 according to the sliding of the spool 1. It is to flow to the other flow path (5a) through the groove (2) concave on the outer peripheral surface of the.
이때, 유로(5)에 주입된 고압유의 압력이 스풀(1) 외주면에 작용하게 되는데 이 압력은 스풀(1)의 이동방향과 동일방향으로 작용하며, 스풀(1)이 슬라이딩하여 제3도에 도시된 바와 같이, 유로(5)(5a)가 좁아짐에 따라 스풀(1)의 요홈(2) 곡면(3)(3a)에 전달되어 곡면을 따라 상, 하로 분산되면서 스풀(1)의 이동방향과 동일방향으로 작용하는 유체력을 상쇄시키게 되면서 스풀(1)의 움직임을 방해하지 않게 되는 것이다.At this time, the pressure of the high-pressure oil injected into the flow path 5 acts on the outer circumferential surface of the spool 1, which acts in the same direction as the moving direction of the spool 1, and the spool 1 slides in FIG. 3. As shown, as the flow paths 5 and 5a are narrowed, they are transferred to the grooves 2 and the curved surfaces 3 and 3a of the spool 1, and are distributed up and down along the curved surfaces, and the moving direction of the spool 1 is moved. While canceling the fluid force acting in the same direction as will not interfere with the movement of the spool (1).
이와 같이 스풀(1)에 가해지는 고압유의 압력을 효과적으로 분산시켜 스풀(1)의 슬라이딩을 원활하게 하므로서, 콘트롤밸브용 스풀(1)과 같이 압력을 포함하지 않는 밸브의 경우에는 스풀(1)의 제어를 스프링만으로도 가능하게 되는 것이며, 스풀(1)의 정확한 스트로크 조작이 가능하여 밸브의 개폐 또는 전환을 미세한 오차없이 수행할 수 있는 것이다.In this way, the pressure of the high pressure oil applied to the spool 1 is effectively distributed to smooth the sliding of the spool 1, so that in the case of a valve that does not contain pressure, such as the control valve spool 1, The spring can be controlled only by the spring, and the precise stroke operation of the spool 1 can be performed to perform opening / closing or switching of the valve without a slight error.
