Description
본 발명은 진공을 이용한 차량용 유체 밸브에 대한 것으로서, 더 상세하게는 전원을 사용하는 것이 아니라 엔진측의 압력 변화에 따라 냉각수의 유로를 차폐할 수 있도록 하는데 특징이 있는 것이다.The present invention relates to a fluid valve for a vehicle using a vacuum, and more particularly, is characterized in that it is possible to shield the flow path of the cooling water according to the pressure change of the engine side, rather than using a power source.
일반적으로 자동차에서는 히터의 냉각수를 제어하기 위해 전자식 밸브를 사용하는 것이 보통이다.In general, the use of electronic valves to control the cooling water of the heater is common in automobiles.
전자식 밸브(1)는 도1에서 보는 바와 같이 유체관(12)의 중단을 차폐할 수 있는 밸브변(13)과, 이 밸브변(13)을 이동시키기 위해 그 축(11)의 중단에 결합한 가동철심(14)과, 상기 가동철심을 전자력을 제공하기 위한 둘레의 자계코일(15)로 이루어 진다.The solenoid valve 1 has a valve side 13 which can shield the interruption of the fluid tube 12 as shown in FIG. 1 and is coupled to the suspension of its shaft 11 to move the valve side 13. The movable iron core 14 and the magnetic field coil 15 of the circumference for providing the electromagnetic force to the movable iron core.
따라서 자계코일(15)에 전원을 공급하면 전자력이 발생하므로 상기한 가동철심(14)이 상승하면 밸브변(13)이 유체관(12)을 개방하게 되고, 반대로 전원을 끊으면 전자력이 없어지므로 상기 가동철심(14)이 하강하여 밸브변(13)이 유체관(12)을 차단하게 되는 것이다.Therefore, when power is supplied to the magnetic field coil 15, an electromagnetic force is generated. When the movable iron core 14 rises, the valve side 13 opens the fluid pipe 12. On the contrary, when the power is cut off, the electromagnetic force is lost. The movable iron core 14 is lowered so that the valve valve 13 blocks the fluid pipe 12.
그러나 상기와 같은 종래의 전자식 밸브는 가격이 고가일 뿐만 아니라 개폐를 제어하기 위해 별도의 콘트롤부와 전원을 연결하여 사용해야 하기 때문에, 제조 및 설치가 어려운 문제가 있다.However, the conventional electronic valve as described above is expensive and has a problem in that it is difficult to manufacture and install because it needs to use a separate control unit and a power source to control the opening and closing.
본 발명은 상기와 같은 종래의 문제점을 해결 보완하기 위해 안출한 것으로 발명의 주된 목적은 엔진측의 냉각수 자켓의 압력에 따라 진공상태가 달라지는 다이아프램을 이용하여 별도의 전원 공급없이 자체적으로 작동할 수 있도록 하는데 있으며, 더 나가서 제조 및 설치가 쉽고, 가격이 저렴한 새로운 밸브를 제공하고자 하는데 있다.The present invention has been made to solve the above-mentioned conventional problems, the main object of the invention can be operated by itself without using a separate power supply using a diaphragm in which the vacuum state varies depending on the pressure of the coolant jacket on the engine side. It aims to provide new valves that are easier to manufacture and install, and that are less expensive.
이를 위한 특징적인 수단은 일측으로 연장된 유입구와, 그 반대쪽으로 연장된 유출구와, 이들 유출구를 지지하되, 내부 중앙에 통공이 마련된 수직부로 이루어 지는 밸브 본체와, 상기한 밸브 본체에 결합하되, 받침부와, 받침부의 상측에 결합한 커버와, 상기 받침부 및 커버의 사이에서 다이아프램으로 지지시킨 가변 플레이트와, 상기한 커버와 가변 플레이트의 사이에 탄설한 스프링으로 구성한 진공 작동부와, 상기한 밸브 본체의 수직부에 내장된 채 승강할 수 있도록 하되, 하단에 밸브 패킹을 결합하고, 상단을 상기한 가변 플레이트의 중앙에 고정하여서된 피스톤축과, 상기한 진공 작동부의 커버에서 인출하여 진공연결기구로 연결한 진공 파이프로 구성하는데 있는 것이다.Characteristic means for this is a valve body consisting of a vertical inlet, the inlet extending to one side, the outlet extending to the opposite side, and these outlets, the vertical portion is provided with a through hole in the inner center, and coupled to the valve body, A vacuum actuator comprising a section, a cover coupled to the upper side of the support, a variable plate supported by a diaphragm between the support and the cover, a spring installed between the cover and the variable plate, and the valve described above.

이하 본 발명의 실시예에 따른 구성 및 작용을 첨부 도면에 따라 보다 상세히 설명하면 다음과 같다.Hereinafter, the configuration and operation according to the embodiment of the present invention will be described in detail with reference to the accompanying drawings.
도 2는 본 발명에 따른 진공을 이용한 차량용 유체 밸브를 보인 것으로서Figure 2 shows a fluid valve for a vehicle using a vacuum according to the present invention
밸브 본체(2)와, 진공 작동부(3)와, 피스톤축(4)과, 진공 파이프(5)로 이루어 진다.It consists of the valve main body 2, the vacuum operation part 3, the piston shaft 4, and the vacuum pipe 5. As shown in FIG.
상기한 밸브 본체(2)는 일측으로 연장된 유입구(21)와, 그 반대쪽으로 연장된 유출구(22)와, 이들 유출구를 지지하되, 내부 중앙에 통공(24)이 마련된 수직부(23)로 이루어 지는 것이고, 진공 작동부(3)는 상기한 밸브 본체에 결합하되, 받침부(31)와, 받침부의 상측에 결합한 커버(32)와, 상기 받침부 및 커버(32)의 사이에서 다이아프램(33)으로 지지시킨 가변 플레이트(34)와, 상기한 커버와 가변 플레이트의 사이에 탄설한 스프링(35)으로 구성한 것이다.The valve body 2 supports the inlet 21 extending to one side, the outlet 22 extending to the opposite side, and the outlet 23 supporting these outlets, and having a vertical portion 23 provided with a through hole 24 in the inner center thereof. The vacuum actuating unit 3 is coupled to the valve body, but the diaphragm is provided between the supporting unit 31 and the cover 32 coupled to the upper side of the supporting unit, and the supporting unit and the cover 32. It consists of the variable plate 34 supported by (33), and the spring 35 extended between the said cover and the variable plate.
또한 피스톤축(4)은 상기한 밸브 본체의 수직부(23)에 내장된 채 승강할 수 있도록 하되, 하단에 밸브 패킹(41)을 결합하고, 상단을 상기한 가변 플레이트(34)의 중앙에 고정하며, 진공 파이프(5)는 상기한 진공 작동부(3)의 커버에서 인출하여 진공연결기구로 연결하는 것이다.In addition, the piston shaft (4) is allowed to be lifted while being embedded in the vertical portion 23 of the valve body, the valve packing 41 is coupled to the lower end, the upper end in the center of the variable plate 34 The vacuum pipe 5 is drawn out from the cover of the vacuum operation unit 3 and connected to the vacuum connection mechanism.
이상과 같이 구성된 본 발명은 평상시 피스톤축(4)이 하강하여 밸브 패킹(41)이 밸브 본체(2)의 내부 통공(24)을 막고 있어 유체의 흐름을 차단하고 있다.In the present invention configured as described above, the piston shaft 4 is usually lowered, and the valve packing 41 blocks the internal through-hole 24 of the valve body 2, thereby blocking the flow of fluid.
이후, 엔진의 냉각수 자켓(도시하지 않았음)의 내부 압력이 떨어지면 그 압력이 진공 파이프(5)를 통해 진공 작동부(3)에 전달되어 피스톤축(4)을 상승시켜 밸브 패킹(41)이 통공(24)을 개방하게 된다.Then, when the internal pressure of the coolant jacket (not shown) of the engine drops, the pressure is transmitted to the vacuum operating part 3 through the vacuum pipe 5 to raise the piston shaft 4 so that the valve packing 41 The opening 24 is opened.
즉, 진공 파이프(5)를 통해 압력이 빠져 나가면 커버(32)와, 가변 플레이트(34) 사이가 진공 상태이기 때문에 둘레가 다이아프램(33)으로 이루어진 가변 플레이트(34)가 스프링(35)의 힘을 이기고 상승하게 된다.That is, when the pressure is released through the vacuum pipe 5, the cover 32 and the variable plate 34 are in a vacuum state, and thus the variable plate 34 made of the diaphragm 33 has a periphery of the spring 35. You win the power and you rise.
따라서 상기한 가변 플레이트(34)의 중앙에 연결되어 있던 피스톤축(4)이 상승하여 통공(24)을 개방하게 되고, 그에 따라 유체가 이동을 할 수 있게 되는 것이다.Therefore, the piston shaft 4 connected to the center of the variable plate 34 is raised to open the through-hole 24, thereby allowing the fluid to move.
그 다음에 유체가 지속적으로 이동하므로서 냉각 자켓의 압력이 높아지면 그 압력이 진공 파이프(5)를 통해 다시 진공 작동부(3)에 전달되므로 피스톤축(4)이 다시 하강하여 통공(24)을 막을 수 있게 된다.Then, when the pressure of the cooling jacket increases as the fluid continuously moves, the pressure is transferred back through the vacuum pipe 5 to the vacuum actuating unit 3 so that the piston shaft 4 lowers again to open the through hole 24. You can stop it.
위에서 상세히 설명한 바와 같은 본 발명은 피스톤축(4)을 승강시켜 그 하단의 밸브 패킹(41)이 통공(24)을 차폐할 수 있도록 하되, 상기 피스톤축(4)은 그 상단을 진공 작동부(3)의 가변 플레이트(34) 중앙에 연결하였기 때문에 진공상태에 따라 승강 작동이 신속하게 이루어 질 뿐만 아니라 종래의 전자 밸브와 달리 전원을 연결할 필요가 없고, 구조가 간단하면서 가격이 저렴하기 때문에 생산성 및 상품성이 크게 향상되는 것이다.The present invention as described in detail above allows the piston shaft 4 to be raised and lowered so that the valve packing 41 at the bottom thereof can shield the through-holes 24, and the piston shaft 4 has a vacuum operating part ( 3) As it is connected to the center of the variable plate 34, the lifting operation is quickly performed according to the vacuum state, and unlike the conventional solenoid valve, there is no need to connect a power supply. Merchandise is greatly improved.
