도 1 내지 도 3을 참조하면, 본 발명은 크게 구분하면 액체유입구(111)을 통해 액체가 유입되는 집수실(120)이 있는 드레인본체(100)와, 상기 집수실(120)에 내장되어 상하방향으로 이동되는 플로트(200)에 의해 구성된다.Referring to Figures 1 to 3, the present invention is largely divided into a drain body 100 having a collecting chamber 120 through which the liquid is introduced through the liquid inlet 111, and is built up in the collecting chamber 120 up and down It is comprised by the float 200 moved to a direction.
따라서, 드레인본체(100)의 집수실(120)은, 상부쪽으로 구성되는 직선내주면(121) 하부쪽에 상부가 넓고 하부로 갈수록 좁아지는 내경을 갖도록 이루어지는 역원뿔형경사내주면(122)을 구비하도록 구성되고, 상기 집수실(120) 하부 중앙에는 배수공(130)을 갖도록 구성된다.Therefore, the collection chamber 120 of the drain body 100 is configured to have an inverted conical inclined inner peripheral surface 122 having an inner diameter wider at the lower portion of the straight inner circumferential surface 121 configured as the upper portion and narrowing toward the lower portion. The center of the lower portion of the collecting chamber 120 is configured to have a drain hole 130.
집수실(120) 상부에는 액체유입구(111)가 있는 상부캡(110)에 체결되도록 하는 것이 바람직하고, 부호 Pa는 액체유입구(111)에 연결되는 입수관을 나타낸 것이다.It is preferable to be fastened to the upper cap 110 having the liquid inlet 111 in the upper part of the collecting chamber 120, and the symbol Pa denotes an inlet pipe connected to the liquid inlet 111.
집수실(120) 하부에 구비되는 배수공(130)은 배수니플(132)에 구비되도록 하여 집수실(120) 하부쪽 드레인본체(100)에 배수니플(132)이 체결되도록 할 수도 있는 것이고, 경우에 따라서는 배수니플(132)을 배제하고 드레인본체(100) 자체에 배수공(130)이 형성되도록 할 수도 있는 것으로서, 이러한 배수공(130) 상부쪽에는 돌기부(131)가 돌출되게 하여 실시될 수도 있는 것이다. 부호 Pb는 배수공(130)에 연결되는 배수관을 나타낸다.The drain hole 130 provided at the bottom of the collecting chamber 120 may be provided at the drain nipple 132 so that the drain nipple 132 may be fastened to the drain main body 100 at the lower side of the collecting chamber 120. In some cases, the drain nipple 132 may be excluded and the drain body 130 may be formed in the drain body 100 itself, and the protrusion 131 may protrude from the upper part of the drain hole 130. will be. Reference numeral Pb denotes a drain pipe connected to the drain hole 130.
플로트(200)는, 내부에 외부연통공기실(210)을 갖도록 구성된다.The float 200 is configured to have an external communication air chamber 210 therein.
상기 외부연통공기실(210)은 상부쪽에 그 외부연통공기실(210)과 연통되는 하나 이상의 압력균형통기공(211)이 구비되도록 구성된다.The external communication air chamber 210 is configured to be provided with one or more pressure balance ventilation holes 211 communicated with the external communication air chamber 210 on the upper side.
상기 외부연통공기실(210)을 구비함으로써 플로트(200)의 무게를 가볍게 하여 플로트(200)가 물 위에 잘 뜨도록 하는 것이 바람직하나 이 경우 플로트(200)의 외주면벽 두께가 얇아지기 때문에 플로트(200) 내외부쪽의 공기압력 차이에 의해서 플로트(200)의 얇은 두께의 외주면벽이 찌그러들게 되는 일그러짐 현상이 발생될 수도 있으므로 본 발명은 플로트(200)의 상부쪽에 외부연통공기실(210)과 연통되는 하나 이상의 압력균형통기공(211)이 구비되도록 함에 따라 플로트(200) 내외부의 공기압력이 항상 동일하게 되어서 플로트(200)가 일그러짐이 없게 되므로 외부연통공기실(210) 외부쪽의 플로트(200) 두께가 얇은 두께를 갖도록 구성되게 할 수 있게 되는 것이고, 그로 인해 플로트(200)가 중량이 가벼워져서 물 위에 잘 뜨게 되는 것일 뿐만 아니라 플로트(200)의 재료절감에 따른 제조원가 절감이 도모된다.The external communication air chamber 210 is provided so that the weight of the float 200 may be reduced so that the float 200 floats well on the water, but in this case, the thickness of the outer circumferential surface wall of the float 200 becomes thin. 200) Since the outer wall of the thin thickness of the float 200 may be distorted due to the difference in air pressure inside and outside, the present invention communicates with the external communication air chamber 210 on the upper side of the float 200. As one or more pressure balance ventilation holes 211 are provided, the air pressure inside and outside the float 200 is always the same, so that the float 200 is not distorted. The thickness of the float 200 may be configured to have a thin thickness, and as a result, the float 200 becomes lighter and floats well on water. Manufacturing costs can be reduced due to material savings.
즉, 본 발명은 플로트(200)가 부력에 의해서 물 위에 잘 상승되게 이동될 수 있도록 하기 위해 플로트(200) 중량을 가급적 가볍게 하는 것이 바람직하지만, 이 경우에는 플로트(200)가 외부 압력에 의해서 찌그러지거나 변형되지 않도록 하여야 하므로 외부연통공기실(210)과 연통되는 하나 이상의 압력균형통기공(211)이 구비되도록 하는 것이다.That is, in the present invention, it is preferable to lighten the weight of the float 200 as much as possible in order to allow the float 200 to be moved well above the water by buoyancy. In this case, the float 200 is crushed by external pressure. It is to be so as not to be deformed or deformed is to be provided with at least one pressure balance vent hole 211 in communication with the external communication air chamber (210).
본 발명의 이해를 돕기 위해, 본 발명과 같은 액체 자동 배출장치는 공기압축기를 이용하여 압축공기를 사용하는 공압시스템에서 압축공기내에 포함되어 있던 액체를 분리시킨 것을 자동으로 배출되게 하는 액체 자동 배출장치로 주로 사용될 수 있다.In order to facilitate understanding of the present invention, the liquid automatic discharge device such as the present invention is an automatic liquid discharge device for automatically discharging the separated liquid contained in the compressed air in the pneumatic system using the compressed air using an air compressor It can be mainly used as.
이 경우에는 액체유입구(111)를 통해서 액체와 함께 압축공기가 유입되어 집수실(120)의 공기압력이 플로트(200)의 외부연통공기실(210) 보다 상대적으로 더 높은 공기압력 상태가 됨으로써 플로트(200)가 압축되어 찌그러질 수도 있다.In this case, the compressed air is introduced together with the liquid through the liquid inlet 111 so that the air pressure of the collecting chamber 120 becomes a relatively higher air pressure than the external communication air chamber 210 of the float 200. 200 may be compressed and crushed.
그러므로 본 발명은 플로트(200)의 압력균형통기공(211)을 통해서 집수실(120)의 공기와 외부연통공기실(210)의 공기가 서로 드나 들어서 통하기 때문에 양쪽의 공기압력이 서로 균등해지게 됨으로써 플로트(200)가 압축되어 일그러지지 않게 되므로 플로트(200)의 기능을 충실히 수행할 수 있게 되는 것이다.Therefore, in the present invention, the air in the collection chamber 120 and the air in the external communication air chamber 210 enter each other through the pressure balance vent hole 211 of the float 200 so that the air pressures of both sides become equal to each other. By doing so, since the float 200 is not compressed and distorted, it is possible to faithfully perform the function of the float 200.
상기와 같이 압력균형통기공(211)을 구비하는 경우에는 압력균형통기공(211) 외측으로 상부가 막히고 하부에 압력균형통기공(211)과 연통되는 통기구(213)가 있는 물차단외벽(212)이 더 구비되도록 구성되는 것으로서, 상기 통기구(213) 상부가 막히도록 하는 것은 공기실덮개부재(260) 테두리부분에 돌출되는 상부차폐부(262)에 의해서 막히도록 하는 것이 바람직하다.When the pressure balancing vent 211 is provided as described above, the water blocking outer wall 212 having the upper portion of the pressure balancing vent 211 outside is blocked and a vent 213 communicating with the pressure balancing vent 211 at the bottom thereof. ) Is further provided, it is preferable to block the upper portion of the vent 213 is blocked by the upper shielding portion 262 protruding to the edge of the air chamber cover member 260.
따라서, 플로트(200) 상부로 낙하되는 액체가 배수로(232)로 흘러 내리는 액체는 물차단외벽(212)에 의해서 차단되어 압력균형통기공(211)으로 들어가지 않게 되는 것일 뿐만 아니라 압력균형통기공(211)과 연통된 통기구(213)가 물차단외벽(212)의 하부쪽으로 구비되므로 물차단외벽(212)을 타고 흘러내리는 액체가 압력균형통기공(211)으로 절대로 유입되지 않게 된다.Therefore, the liquid falling down to the float 200 flows into the drainage passage 232 is not only blocked by the water blocking outer wall 212 and does not enter the pressure balance vent hole 211, but also the pressure balance vent hole Since the air vent 213 communicating with the 211 is provided toward the lower side of the water blocking outer wall 212, the liquid flowing down the water blocking outer wall 212 is never introduced into the pressure balancing vent 211.
그러므로 본 발명은 외부연통공기실(210) 내부에 물이 흡입되는 것이 미연에 방지되기 때문에 외부연통공기실(210) 내부에 물이 흡입됨에 따라 발생될 수 있는 부력 약화 현상이 전혀 발생되지 않게 되므로 플로트(200) 기능을 충실히 수행할 수 있게 되는 것이다.Therefore, since the inhalation of water in the external communication air chamber 210 is prevented in advance, the present invention does not cause any buoyancy decay that may occur when water is sucked into the external communication air chamber 210. Float 200 will be able to faithfully perform the function.
도 1 및 도 2를 참조하면, 공기실덮개부재(260) 상면부에는 도 1 및 도 2에 나타낸 바와 같이 테두리부분에서 중앙방향으로 경사지는 오목형태로 이루어지는 집중압력작용홈부(261)를 구비하도록 구성된다.1 and 2, the upper surface portion of the air chamber cover member 260 is provided with a concentrated pressure action groove 261 formed in a concave shape inclined toward the center from the edge as shown in FIGS. 1 and 2. It is composed.
상기 공기실덮개부재(260)는 외부연통공기실(210) 상부쪽 플로트(200)에 고정되게 구비되는 것으로서, 가령 강력접착제에 의해 부착되어 고정되게 하거나 또는 다른 고정수단을 이용하여 고정되도록 할 수도 있다.The air chamber cover member 260 is provided to be fixed to the float 200 in the upper side of the external communication air chamber 210, for example, may be attached or fixed by a strong adhesive, or may be fixed using other fixing means. have.
그러나 본 발명은 외부연통공기실(210)을 갖도록 하면 되는 것이므로, 가령 별도의 공기실덮개부재(260)를 구비하지 않고 공기실덮개부재(260)와 직립부(2200가 일체로 구성되게 하고 상부쪽에 집중압력작용홈부(261)가 구비되도록 구성되게할 수도 있는 것이다.However, since the present invention is to have an external communication air chamber 210, for example, without having a separate air chamber cover member 260, the air chamber cover member 260 and the upright part 2200 are integrally formed and It may be configured to be provided with a concentrated pressure action groove 261 on the side.
한편, 외부연통공기실(210)를 갖는 플로트(100)는, 상부쪽으로 직립부(220)를 구비하고 상기 직립부(220) 하부에 역원뿔형경사내주면(122)과 동일한 형태로 이루어지는 역원뿔형경사부(221)를 갖도록 구성된다.On the other hand, the float 100 having an external communication air chamber 210 has an upright portion 220 toward the upper side and a reverse conical slope having the same shape as the reverse conical inclined inner circumferential surface 122 below the upright portion 220. It is configured to have a portion 221.
또한, 상기 역원뿔형경사부(221) 외주면에는 역원뿔형경사내주면(122)과 정합될 수 있도록 하기 위해 하부방향으로 경사지게 돌출되는 다수의 하향경사리브(230)를 구비하도록 구성됨으로써 상기한 다수의 하향경사리브(230) 사이에는 각각의 배수로(231)를 갖도록 구성된다.In addition, the outer conical inclined portion 221 has a plurality of downward inclined ribs protruding obliquely downward in order to be matched with the inverted conical inclined inner circumferential surface 122, the plurality of downwards The inclined ribs 230 are configured to have respective drainage passages 231.
상기 다수의 하향경사리브(230) 상부쪽으로는 도 2에 나타낸 바와 같이 하향경사리브(230)와 연장되는 직선리브(230a)를 직립부(220)에 구비하도록 하는 것이 바람직하다.As shown in FIG. 2, the plurality of downhill ribs 230 may be provided with the straight ribs 230a extending in the upright part 220.
상기 직선리브(230a)는, 도 3 및 도 4에 나타낸 바와 같이 직선내주면(121)에 외단부가 접촉되게 형성시킴으로써 플로트(200)의 직립부(220)가 수직방향으로 이동 가능하도록 하는 것이 바람직하고, 이 경우 직선리브(230a) 외단부는 라운딩되게 함으로써 직선리브(230a)와 직선내주면(121)이 선접촉되는 상태로 이동되는 상태가 됨에 따라 양호한 이동이 이루어지도록 하는 것이 바람직하다. 3 and 4, the straight ribs 230a preferably have the outer end portion in contact with the straight inner circumferential surface 121 so that the upright portion 220 of the float 200 can move in the vertical direction. In this case, it is preferable that the outer end of the straight rib 230a is rounded so that a good movement is achieved as the straight rib 230a and the straight inner circumferential surface 121 are moved in line contact state.
역원뿔형경사부(221) 하부 중앙에는 개폐돌륜부(240)가 돌출됨으로써 플로트(200) 하부에 부력생성공간부(250)가 형성되도록 구성된다.The opening and closing wheel part 240 protrudes in the lower center of the reverse conical inclined portion 221 so that the buoyancy generating space 250 is formed in the lower portion of the float 200.
개폐돌륜부(240)에는 하부쪽으로 개방되는 출몰홈부(241)를 구비하고, 상기 요홈부(242) 내부에는 패킹(242)이 삽입되도록 구성되게 함으로써, 상기 요홈부(242) 안쪽으로 도 1에 나타낸 바와 같이 배수공(130)이 있는 돌륜부(131)가 삽입되어 배수공(130)이 패킹(242)에 밀착됨에 따라 배수공(130)이 더욱 확실하게 폐쇄될 수 있도록 하는 것이 바람직하다.The opening and closing wheel part 240 is provided with a recessed groove 241 which is opened to the lower side, and the packing 242 is inserted into the recess 242, so that the recess 242 inside the recess 242 in FIG. As shown, it is preferable to insert the protrusion part 131 having the drain hole 130 so that the drain hole 130 can be more surely closed as the drain hole 130 is in close contact with the packing 242.
본 발명은 액체유입구(111)를 통해서 액체가 집수실(120)로 유입되어 플로트(200) 상부면으로 낙하하게 되는데, 이때, 액체가 도 1에서 화살표방향과 같이 직선적으로 낙하되면 집중압력작용홈부(261)로 낙하되어서 사방으로 퍼져 나가게 되는 상태가 되어 플로트(200) 외주면에 있는 배수로(231)를 통해서 하측방향으로 흘러 내려가게 된다.In the present invention, the liquid flows into the collecting chamber 120 through the liquid inlet 111 and falls to the upper surface of the float 200. At this time, when the liquid falls linearly as shown by the arrow in FIG. It falls to 261 and is spread | emitted in all directions, and it flows down through the drainage path 231 in the outer peripheral surface of the float 200.
이때, 집중압력작용홈부(261)가 공기실덮개부재(260) 상부면 테두리부분에서 중앙방향으로 경사지는 오목형태로 이루어져 있기 때문에 액체는 집중압력작용홈부(261) 중앙으로 자연스럽게 모여지는 상태가 됨으로써 집중중앙홈부(261) 중앙에는 액체 하중이 실리게 되는 상태가 됨에 따라 플로트(200)의 상부쪽 중앙부는 상부쪽 외주연부 보다는 상대적으로 집중적으로 액체 하중력을 더 받게 되는 상태가 된다.At this time, since the concentrated pressure action groove 261 is formed in a concave shape inclined toward the center from the edge of the upper surface of the air chamber cover member 260, the liquid is naturally gathered to the center of the concentrated pressure action groove 261. As the liquid load is loaded in the center of the concentrated central groove 261, the upper center portion of the float 200 is in a state in which the liquid load is more concentrated than the upper outer peripheral portion.
그러므로 플로트(200) 중앙부가 집중적으로 액체 하중력을 받게 되므로 플로트(200) 중앙부가 더 많은 집중압력을 받게 됨에 따라 하부쪽 중앙에 있는 개폐돌륜부(240)가 더욱 강한 압력으로 배수공(130)을 차폐할 수 있게 되는 것이다.Therefore, since the center portion of the float 200 receives the concentrated liquid load, the center portion of the float 200 receives more concentrated pressure, so that the opening and closing wheel 240 in the lower center has a higher pressure to drain the drain hole 130. It will be able to shield.
즉, 본 발명은 개폐돌륜부(240)가 배수공(130)을 차폐하는 압력이 플로트(200)의 자체 하중으로만 가압되어 차폐하는 것이 아니고 플로트(200)의 자체 하중 뿐만 아니라 플로트(200) 중앙부가 더 많은 집중압력을 받게 됨에 따라 하부쪽 중앙에 있는 개폐돌륜부(240)가 더욱 강한 압력으로 배수공(130)을 차폐할 수 있게 되므로 더욱 확실한 배수공(130) 차폐가 도모되는 특징이 있는 것이다.That is, in the present invention, the pressure of the opening and closing wheel part 240 to shield the drain hole 130 is not limited to being pressed by the own load of the float 200, and not only the own load of the float 200 but also the center portion of the float 200. As the more concentrated pressure is received, the opening and closing wheel part 240 in the center of the lower side can shield the drain hole 130 at a higher pressure, so that the more reliable drain hole 130 is shielded.
도 1를 참조하면, 배수로(231)를 따라 흘러 내린 액체는 부력생성공간부(250)에 채워지게 되어 점차적으로 상부쪽의 배수로(231)까지 차 오르게 되는 것으로서, 도 1에서 가상선으로 도시된 물수위선(W)까지 액체가 차 오르게 되면 부력에 의해서 플로트(200)가 상부방향으로 떠 올라서 이동되는 상태가 되는 것이다. 상기한 물수위선(W)은 본 발명의 이해를 돕기 위해 도시된 것일 뿐이고 실제 제품에는 없는 것이다.Referring to FIG. 1, the liquid flowing down the drainage passage 231 is filled in the buoyancy generating space 250 and gradually rises to the drainage passage 231 at the upper side, which is shown as a virtual line in FIG. 1. When the liquid rises up to the water level line (W), the float 200 floats upward due to buoyancy and is moved. The above water level line (W) is only shown to help the understanding of the present invention and is not present in the actual product.
따라서, 플로트(200)가 상부방향으로 떠 올라가게 되면 개폐돌륜부(240)가 상부쪽으로 이동되어 돌기부(131)에서 떨어지게 되므로 배수공(130)이 개방됨에 따라 부력생성공간부(250)에 있는 액체가 배수공(130)으로 배출된다.Therefore, when the float 200 floats upward, the opening / closing protrusion 240 moves upward and falls from the protrusion 131, so that the liquid in the buoyancy generating space 250 is opened as the drain hole 130 is opened. Is discharged to the drain hole (130).
그러므로 액체가 배수공(130)으로 배출되는 동안 플로트(200)는 점차 하부방향으로 내려가게 되는데, 이때 본 발명은 도 3 및 도 4에 나타낸 바와 같이 플로트(200)의 직립부(220)에 있는 직선리브(230a) 외단부와 직선내주면(121)이 접촉되는 상태로 구성되어 있기 때문에 플로트(200)가 상승되게 이동된 상태에서도 일측으로 기울어지지 않게 되고 일직선상태로 상승되게 이동되거나 또는 하강되게 이동되는 상태가 되는 것일 뿐만 아니라 플로트(200)가 하강되게 이동되면서 도 5의 (b)에 나타낸 바와 같이 하향경사리브(230)가 역원뿔형경사내주면(122)과 자동으로 일치되어 정합되는 상태가 되기 때문에 개폐돌륜부(240)의 끝단부가 배수공(130)의 수직중심선(S)과 일치되는 상태가 됨으로써 배수공(130)이 차폐되는 상태가 되는 것이다.Therefore, while the liquid is discharged to the drain hole 130, the float 200 is gradually lowered, wherein the present invention is a straight line in the upright portion 220 of the float 200 as shown in Figs. Since the outer end portion of the rib 230a and the straight inner circumferential surface 121 are in contact with each other, the float 200 is not tilted to one side even when the float 200 is moved up, and is moved up or down in a straight state. In addition to being in a state, as the float 200 moves downward, as shown in (b) of FIG. 5, the downward slope rib 230 automatically matches with the inverse conical inclined inner circumferential surface 122, so that the state is matched. The end portion of the opening and closing wheel part 240 is in a state where the vertical center line (S) of the drain hole 130 is in a state where the drain hole 130 is shielded.
따라서, 상기와 같이 배수공(130)이 차폐된 상태가 되면 배수로(231)를 타고 내려오게 되는 액체가 다시 부력생성공간부(250)에 채워지게 되는 상태가 되어서 도 1에 나타낸 바와 같이 액체가 다시 물수위선(W)까지 차오르게 되면 다시 플로트(200)가 부력에 의해서 상승되게 이동됨으로써 개폐돌륜부(240)에 의해 막혀있던 배수공(130)이 다시 개방되어 액체가 배수관(Pb)으로 다시 배수되는 작용을 반복적으로 하게 됨으로써 액체가 수시로 자동으로 배출되는 것이다.Therefore, when the drain hole 130 is shielded as described above, the liquid coming down the drain passage 231 is filled in the buoyancy generating space 250 again, and the liquid is again shown in FIG. 1. When the water level line (W) is filled up, the float 200 is moved again by buoyancy, so that the drain hole 130 blocked by the opening and closing wheel part 240 is opened again, and the liquid is drained back to the drain pipe Pb. By repeating the action, the liquid is discharged automatically from time to time.
따라서, 본 발명은 플로트(200)가 부력에 의해서 상승되게 이동되게 작동되어 배수공(130)이 개방되게 한 것이기 때문에, 플로트(200)를 채용하는데 있어서 자재 가격이 상대적으로 매우 높은 비중이 낮은 재질로 반드시 플로트(200)를 제조하여 채용되게 하지 않아도 되고, 상대적으로 자재 가격이 월등이 낮은 비중이 다소 높은 재질의 플로트(200)가 채용되게 할 수 있는 것이므로, 플로트(20) 비중에 전혀 관계 없이 양호하게 동작되는 액체 자동 배출장치를 제공하게 되는 것이다.Therefore, since the float 200 is operated to move up by the buoyancy to open the drain hole 130, the present invention employs a material having a relatively high specific gravity in employing the float 200. It is not necessary to manufacture and employ the float 200, and because it is possible to employ a float 200 of a material having a relatively high proportion of material having a relatively low material price, and thus good regardless of the specific gravity of the float 20. It is to provide an automatic liquid discharge device that is operated.
본 발명의 이해를 돕기 위해, 기존에는 물보다 비중이 낮는 플로트가 채용되어야 만이 액체 자동 배출이 되었지만, 본 발명은 부력이 증가 되므로 물보다 비중이 높은 플로트(200)가 채용되어도 액체 자동 배출이 이루어질 수 있는 것이고, 아울러서 물보다 비중이 낮은 플로트는 재료 구입단가가 상대적으로 매우 높은 반면에 물보다 비중이 높은 플로트(200)는 상대적으로 재료 구입단가가 상대적으로 휠씬 낮기 때문에 제조원가 절감이 도모되는 것이므로 성능이 향상된 자동 액체 배출장치를 매우 저렴하게 보급 가능하게 된다.In order to facilitate the understanding of the present invention, conventionally, the liquid discharged only when a float having a specific gravity lower than that of water was used. However, the present invention, since the buoyancy is increased, even when a float 200 having a specific gravity higher than water is employed, automatic discharge of liquid is achieved. In addition, the float having a lower specific gravity than water has a relatively high material purchase cost, while the float 200 having a higher specific gravity than water has a relatively low material purchase cost, thereby reducing manufacturing costs. This improved automatic liquid dispensing device becomes very inexpensive.
따라서, 본 발명은 바람직하게는 플로트(200)가 물보다 높은 비중을 갖도록 하되 최대한 비중을 낮게 구성하고 부력이 최대한 증가되게 하여 양호하게 동작되도록 하는 것이 바람직하다.Therefore, the present invention preferably float 200 has a specific gravity higher than the water, but it is preferable to make the specific gravity as low as possible and to increase the buoyancy as possible to ensure good operation.
그리고 본 발명은 액체가 집중압력작용홈부(261) 중앙으로 자연스럽게 모여지는 상태가 됨으로써 플로트(200) 중앙부가 더 많은 집중압력을 받게 됨에 따라 하부쪽 중앙에 있는 개폐돌륜부(240)가 더욱 강한 압력으로 배수공(130)을 차폐할 수 있게 되는 것이므로 액체유입구(111)로 유입되는 액체가 분산되어 유입되거나 또는 일직선상태로 유입되는 것에 관계 없이 실시되고 채용될 수 있는 것이다.In the present invention, the liquid is naturally collected in the concentrated pressure acting groove 261, so that the central portion of the float 200 receives more concentrated pressure, so that the opening and closing wheel part 240 in the lower center has a stronger pressure. In order to shield the drain hole 130, the liquid flowing into the liquid inlet 111 is dispersed and introduced or may be implemented and employed regardless of being introduced in a straight state.
또한, 집수실(120) 내부 압력이 높아도 플로트(200)가 일그러지지 않고 본연의 역할을 수행하게 되므로 액체 유입압력에 전혀 영향을 받지 않고 양호하게 액체 자동 배출이 이루어지게 되는 것이므로 범용으로 사용될 수 있는 액체 자동 배출장치를 제공하게 되는 것이다.In addition, even if the internal pressure of the collection chamber 120 is high, since the float 200 does not distort and performs its role, it is not affected by the liquid inflow pressure at all, and the liquid is automatically discharged well. It will provide an automatic liquid discharge device.
한편, 본 발명은 도 3 및 도 4에 나타낸 바와 같이 플로트(200)의 직립부(220)에 있는 직선리브(230a) 외단부와 직선내주면(121)이 접촉되는 상태로 구성되게 실시되도록 하는 것이 바람직하지만, 경우에 따라서는 플로트(200)의 직경에 비해 직선내주면(121)의 내경을 크게 구성되게 하여 직선리브(230a) 외단부가 직선내주면(121)에 접촉되지 않도록 구성되게 실시될 수도 있다.Meanwhile, the present invention is implemented such that the outer end portion of the straight rib 230a in the upright portion 220 of the float 200 and the straight inner circumferential surface 121 are in contact with each other as shown in FIGS. 3 and 4. Preferably, however, in some cases, the inner diameter of the straight inner circumferential surface 121 may be larger than the diameter of the float 200 so that the outer end portion of the straight rib 230a may not be in contact with the straight inner circumferential surface 121. .
이 경우에는 플로트(200)가 부력에 의해서 상승되게 이동되면 플로트(200)가 일측방향으로 기울어질 수 있어서 도 5의 (a)에 도시된 바와 같이 역원뿔형경사부(221)와 그 외주면에 구비되는 하향경사리브(230)도 기울어지게 됨으로써 역원뿔형경사내주면(122)과 하향경사리브(230) 사이에 유격(K)이나 틈새가 필연적으로 발생되어 배수공(130)의 수직중심선(S)과 개폐돌륜부(240)가 수직 상태로 일치되지 않게 되는 상태가 된다. In this case, when the float 200 is moved up by the buoyancy, the float 200 may be inclined in one direction, and thus, the float 200 may be provided on the reverse conical inclined portion 221 and its outer circumferential surface. Since the downward inclination rib 230 is also inclined, a clearance K or a gap is inevitably generated between the inverted conical inclined inner circumferential surface 122 and the downward inclination rib 230 to open and close the vertical center line S of the drain hole 130. The wheel wheels 240 are in a state where they are not aligned in a vertical state.
그러나 본 발명은 상기와 같은 유격(K)이 발생되어 배수공(130)의 수직중심선(S)과 개폐돌륜부(240)가 수직 상태로 일치되지 않게 되어도 플로트(200)가 하강되게 이동되면 역원뿔형경사내주면(122)에 하향경사리브(230)가 접촉되면서 점차적으로 내려가기 때문에 플로트(200)가 점차적으로 수직방향으로 세워지는 상태가 되면서 최종적으로는 도 5의 (b)에 나타낸 바와 같이 하향경사리브(230)가 역원뿔형경사내주면(122)에 정합되는 상태로 안착됨에 따라 배수공(130)의 수직중심선(S)과 개폐돌륜부(240)가 자동으로 일치됨으로써 배수공(130)을 차폐하게 되는 것이다.However, in the present invention, if the clearance (K) is generated as described above, even if the vertical center line (S) of the drain hole 130 and the opening and closing wheel part 240 do not coincide in a vertical state, the float 200 is moved downwardly. As the downwardly inclined rib 230 contacts the inclined inner circumferential surface 122, the downwardly inclined rib 230 gradually descends, and as a result, the float 200 is gradually erected in the vertical direction, and finally, as shown in FIG. As the rib 230 is seated in a state in which it is fitted to the inverse conical inclined inner circumferential surface 122, the vertical center line S of the drain hole 130 and the opening and closing wheel part 240 are automatically matched to shield the drain hole 130. will be.
그러므로 본 발명은 도면으로 도시되고 설명된 것에 반드시 국한 되는 것은 아니고 본 발명이 속하는 기술분야의 통상의 지식을 가진 자에 의해서 여러 가지로 변형 실시될 수도 있는 것이므로 청구범위를 크게 벗어나지 않는 한 폭넓게 보호되어야 하는 것은 자명한 것이다.Therefore, the present invention is not necessarily limited to those illustrated and described in the drawings, and may be variously modified by those skilled in the art to which the present invention pertains, and therefore, the present invention should be broadly protected without departing from the scope of the claims. It is self-evident.

또한, 플로트 중량이 감소된 것이 채용 가능하도록 함에 따라 재료 절감에 따른 원가절감이 도모되어 성능이 우수한 제품을 보다 저렴하게 보급할 수 있게 됨으로써 대내외적으로 높은 경쟁력을 확보할 수 있게 되는 효과가 있는 것으로서, 식품이나 각종 제품을 생산하기 위해 압축공기를 이용하는 유공압 자동화 생산설비에서 공압파이프를 통과하는 압축공기에서 수분을 제거하여 자동으로 배출되게 하는 액체 자동 배출장치로 이용할 수 있고 가격이 저렴하고 제품신뢰성이 크게 향상된 액체 자동 배출장치를 보급하게 되었다.In addition, as the float weight is reduced, it is possible to reduce the cost of material savings, thereby enabling the supply of high-performance products at a lower cost, thereby securing a high competitiveness both internally and externally. It can be used as a liquid automatic discharge device that removes moisture from the compressed air passing through the pneumatic pipe and automatically discharges it in the automated pneumatic production facility that uses compressed air to produce food or various products. Advanced liquid automatic ejectors have been introduced.
