에어컴프레서의 응축수 드레인밸브장치{THE DRAIN VALVE DEVICE OF AIR COMPRESSOR}Condensate drain valve device for air compressors {THE DRAIN VALVE DEVICE OF AIR COMPRESSOR}

본 발명은 에어컴프레서의 응축수 드레인밸브장치에 관한 것으로, 특히 압력차를 유도하여 응축수의 배출이 원활히 이루어지도록 한 에어컴프레서의 응축수 드레인밸브장치에 관한 것이다.The present invention relates to a condensate drain valve device of an air compressor, and more particularly, to a condensate drain valve device of an air compressor to induce a pressure difference to facilitate the discharge of condensate.

일반적으로 에어컴프레서는 공기를 대기압 이상의 압력으로 압축하여 압축 공기를 만드는 장치를 말하며, 최근 고도로 발전하는 자동화시스템에서 공압기기를 구동시키는데 필요한 압축공기를 생성해서 공급하는 역할을 수행한다. 이러한 에어컴프레서에는 공기가 빠져나가면서 압력이 급히 내려가고 이로 인해 온도가 갑자기 내려감으로써 응축수가 자연스럽게 생성된다.In general, an air compressor is a device that compresses air to a pressure above atmospheric pressure to make compressed air, and plays a role of generating and supplying compressed air required to drive a pneumatic device in a recently developed automation system. In such air compressors, the pressure quickly drops as the air escapes, and the condensed water is naturally generated by suddenly lowering the temperature.

이와 같이 생성되는 응축수는 외부로 배출되며, 한국 등록실용신안공보 20-0292474호, 한국 공개특허공보 특2002-0060889호 등에서 개시된 바와 같이 에어컴프레서에 응축수 배출관을 설치하고, 그 배출관의 중간에 수동으로 작동하거나 솔레노이드를 사용해서 자동으로 작동하는 볼밸브를 설치하여 응축수를 배출하고 있다.The condensate generated in this way is discharged to the outside, and as shown in Korean Utility Model Publication No. 20-0292474, Korean Patent Application Publication No. 2002-0060889, etc., a condensate discharge pipe is installed in an air compressor, and manually in the middle of the discharge pipe. Condensate is discharged by installing a ball valve that operates or automatically operates using a solenoid.

그러나, 예컨대 낡은 피스톤식 에어컴프레서에서 생성되는 응축수는 오일과 녹 등의 이물질을 많이 함유하고 있기 때문에, 응축수 배출관 또는 볼밸브가 그 이물질들로 막히는 현상이 자주 발생했다.However, since the condensate generated in the old piston type air compressor contains a lot of foreign substances such as oil and rust, the condensate discharge pipe or the ball valve frequently occurs.

이하, 본 발명의 바람직한 실시예를 첨부한 도면을 참조하여 상세히 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in detail.

도 3a 및 도 3b는 본 발명의 에어컴프레서의 응축수 드레인밸브장치의 작동원리를 순차로 나타낸 도면이다.3A and 3B are views sequentially showing the operating principle of the condensate drain valve device of the air compressor of the present invention.

도 4는 도 2에서 응축수유입 차단수단의 작동 원리를 나타낸 도면이다.4 is a view showing the operating principle of the condensate inlet blocking means in FIG.

도면에 나타낸 바와 같이, 본 발명의 에어컴프레서의 응축수 드레인밸브장치는 에어컴프레서(1)에서 생성되는 응축수를 외부로 배출하기 위한 장치이며, 응축수 드레인수단(20)과 감압수단(50)으로 대별된다.As shown in the figure, the condensate drain valve device of the air compressor of the present invention is a device for discharging the condensate generated by the air compressor 1 to the outside, and is roughly divided into condensate drain means 20 and decompression means 50. .

드레인수단(20)은 에어컴프레서(1)에서 생성되는 응축수를 집수한 후 일정 수위가 되면 외부로 배출하는 역할을 하고, 감압수단(50)은 에어컴프레서(1)와 드레인수단(20)과의 사이에 압력차를 형성하여 그 압력차로 인해 에어컴프레서(1)의 응축수가 드레인수단(20)으로 원활히 이동할 수 있도록 해 준다.The drain means 20 collects the condensed water generated by the air compressor 1 and discharges it to the outside when the water level reaches a predetermined level, and the decompression means 50 between the air compressor 1 and the drain means 20. By forming a pressure difference between the condensed water of the air compressor (1) due to the pressure difference allows to smoothly move to the drain means (20).

드레인수단(20)은 관(21)을 통해서 에어컴프레서(1)와 연락하게 연결되는 하부에 배출구(23)를 갖는 저장탱크(25)를 구비하여 에어컴프레서(1)에서 생성되는 응축수를 저장탱크(25)에서 집수하고, 예컨대 제2부구(28a)를 갖는 개폐수단(28)을 배출구(23)에 설치하여 일정수위가 되면 배출구(23)를 개방해서 응축수를 배출한다.The drain means 20 is provided with a storage tank 25 having a discharge port 23 at a lower portion connected to the air compressor 1 through a pipe 21 to store the condensed water generated in the air compressor 1. The water is collected at 25 and, for example, an opening / closing means 28 having a second mouth 28a is installed at the outlet 23 so that the condensed water is discharged by opening the outlet 23 at a predetermined level.

즉 개폐수단(28)의 제2부구(28a)는 연결부재(28b)를 통해서 배출구(23)와 인접하게 입설되는 지지대(28c)의 끝단에 회전되게 연결되고, 연결부재(28b)의 중간에는 피스톤 모양의 개폐구(28d)를 회전되게 설치하여, 저장탱크(25) 내의 수위가 일정수위가 되면 제2부구(28a)가 수위를 따라 시계방향으로 회전하여 개폐구(28d)를 들어 올림으로써 배출구(23)를 개방하여 응축수를 배출한다. 지지대(28c)는 중 간에 개폐구(28d)를 끼울 수 있는 링 형상의 가이드부재(28e)를 설치하여 개폐구(28d)의 상하 이동을 가이드하고 있다(도 3a 참조).That is, the second opening 28a of the opening and closing means 28 is rotatably connected to the end of the support 28c which is placed adjacent to the outlet 23 through the connecting member 28b, and in the middle of the connecting member 28b. When the piston-shaped opening and closing hole 28d is installed to rotate, and the water level in the storage tank 25 reaches a certain level, the second sub-hole 28a rotates clockwise along the water level to lift the opening and closing hole 28d. 23) open to drain the condensate. The support 28c is provided with a ring-shaped guide member 28e through which the opening and closing opening 28d can be inserted to guide the vertical movement of the opening and closing opening 28d (see FIG. 3A).

이와 달리 도시하지는 않았지만, 저장탱크(25)의 소정 위치에 수위감지센서를 설치하고, 그 센서의 전기적 신호를 받아 작동하는 솔레노이드를 개폐구(28d)에 연결 설치하여, 일정수위가 되면 센서의 지시로 솔레노이드가 개폐구(25d)를 들어 올림으로써 배출구(23)를 개방하여 응축수를 배출할 수 있다.Unlike this, although not shown, a water level sensor is installed at a predetermined position of the storage tank 25, and a solenoid operated by receiving an electrical signal of the sensor is connected to the opening and closing port 28d, and when the water level reaches a certain level, The solenoid can lift the opening and closing port 25d to open the discharge port 23 and discharge the condensed water.

이처럼 일정량의 응축수를 모았다가 일정 시점에서 배출구(23)를 순간적으로 개방하여, 높은 수압에 의해 각종 이물질이 신속하게 배출되도록 함으로서, 배출구(23)가 막히는 현상이 발생하지 않는다.As such, after collecting a certain amount of condensed water, the outlet 23 is instantaneously opened at a certain time, and various foreign substances are quickly discharged by high water pressure, so that the outlet 23 is not clogged.

감압수단(50)은 저장탱크(25)의 상부에 설치되어, 배출구(23)가 폐쇄됨으로써 저장탱크(25)가 밀폐되면, 저장탱크(25) 내의 공기압을 감압함으로써, 에어컴프레서(1)와 저장탱크(25)와의 사이에 압력차를 형성하여 그 압력차로 인해 응축수가 원활히 이동할 수 있도록 해 준다(도 3b 참조).The decompression means 50 is installed on the upper portion of the storage tank 25, and when the storage tank 25 is closed by closing the outlet 23, the air pressure in the storage tank 25 is reduced, thereby reducing the pressure of the air compressor 1. The pressure difference is formed between the storage tank 25 so that the condensed water can smoothly move due to the pressure difference (see FIG. 3B).

즉 저장탱크(25) 내의 응축수가 모두 배출되어 배출구(23)가 폐쇄되면, 저장탱크(25)에는 공기가 가득 차는데, 그 저장탱크(25)의 공기압에 의해서 에어컴프레서(1)에서 생성되는 응축수가 저장탱크(25)로 흘러 들어가지 못하는 일이 발생한다. 즉, 저장탱크(25)의 공기압이 에어컴프레서(1)의 공기압보다 크기 때문에 응축수가 저장탱크(25)로 흘러 들어가지 못하는 일이 발생한다.That is, when all the condensed water in the storage tank 25 is discharged and the outlet 23 is closed, the storage tank 25 is filled with air, and the condensed water generated in the air compressor 1 by the air pressure of the storage tank 25. Does not flow into the storage tank 25 occurs. That is, since the air pressure of the storage tank 25 is greater than the air pressure of the air compressor 1, the condensed water may not flow into the storage tank 25.

이 때문에 저장탱크(25)와 에어컴프레서(1)와의 사이에 연결관을 설치하여 저장탱크(25)와 에어컴프레서(1)의 공기압을 같게 만들 수 있지만, 그러면 응축수 가 오직 중력의 영향을 받아 저장탱크(25)로 흘러 들어가기 때문에, 작은 이물질에도 응축수를 이동시키는 관(21)이 막히는 현상이 발생한다.For this reason, a connecting pipe can be provided between the storage tank 25 and the air compressor 1 to make the air pressure of the storage tank 25 and the air compressor 1 the same, but the condensate is then stored under the influence of gravity only. Since it flows into the tank 25, the phenomenon that the pipe 21 which moves condensed water also clogs even small foreign substances arises.

그러나, 상술한 바와 같이 저장탱크(25)에 감압수단(50)을 설치하여 저장탱크(25)의 공기압을 에어컴프레서(1)의 공기압보다 낮게 유지하면, 양쪽의 압력차로 인해서 에어컴프레서(1)의 응축수가 저장탱크(25)로 용이하게 흘러 들어갈 수 있고, 이로 인해 관(21)의 막힘 현상이 발생하지 않는다. 또한 저장탱크(25)를 어떤 위치에 설치하더라도 응축수를 효과적으로 배출할 수 있다.However, as described above, when the pressure reducing means 50 is installed in the storage tank 25 and the air pressure of the storage tank 25 is kept lower than the air pressure of the air compressor 1, the air compressor 1 is caused by the pressure difference between the two. Condensate can easily flow into the storage tank (25), thereby preventing clogging of the tube (21). In addition, even if the storage tank 25 is installed in any position can effectively discharge the condensate.

이를 위해, 감압수단(50)은 내부가 빈 통체를 이루어 하부에는 저장탱크(25)와 연락하는 연락공(51a)을 형성하고 상부에는 내외부를 연락하는 공기배출로(51b)를 형성한 몸체(51)를 구비하여, 연락공(51a)으로부터 유입되는 저장탱크(25)의 공기를 공기배출로(51b)로 배출함으로써, 저장탱크(25) 내의 공기압을 감압하고 있고, 또한 몸체(51)에는 공기배출로(51b)의 개구 크기를 조절하는 감압조절수단(53)을 설치하여 감압 크기를 조절하고 있다. 감압조절수단(53)은 저장탱크(25)의 크기 등에 따라 공기배출로(51b)의 개구 크기를 조절하여 감압 크기를 조절한다.To this end, the decompression means 50 has a hollow cylinder inside to form a contact hole 51a in contact with the storage tank 25 at the bottom, and an air discharge passage 51b in contact with the inside and outside at the top ( 51, the air in the storage tank 25 flowing from the communication hole 51a is discharged to the air discharge path 51b, whereby the air pressure in the storage tank 25 is reduced, and the body 51 The pressure reduction control means 53 for adjusting the opening size of the air discharge passage 51b is installed to adjust the size of the pressure reduction. The pressure reduction control unit 53 adjusts the size of the pressure reduction by adjusting the opening size of the air discharge passage 51b according to the size of the storage tank 25.

이때, 공기배출로(51b)는 몸체(51)의 내부로부터 외벽면을 향해 수평으로 형성되고, 감압조절수단(53)은 외주연에 나사를 형성한 원기둥 형상을 이루되 일단(53a)을 끝으로 갈수록 폭이 좁아지는 삼각형상을 이루어 그 삼각형상의 일단(53a)이 공기배출로(51b)와 대면하여 개구 크기를 조절하도록 공기배출로(51b)와 동일선상이 되게 즉, 일직선이 되게 몸체(51)에 나사 결합되어, 감압 크기를 조절한다. 즉, 감압조절수단(53)은 그 출몰 길이를 조절하여 공기배출로(51b)의 개구 크기를 조절함으로써 감압 크기를 조절한다.At this time, the air discharge passage (51b) is formed horizontally from the inside of the body 51 toward the outer wall surface, decompression control means 53 forms a cylindrical shape with a screw formed on the outer periphery, but ends one end (53a) To form a triangular shape becomes narrower toward the end so that one end (53a) of the triangular face is in line with the air discharge path (51b) to adjust the size of the opening facing the air discharge path (51b), that is, the body ( 51) is screwed on, to adjust the size of the reduced pressure. That is, the depressurization control means 53 adjusts the size of the depressurization by adjusting the bulge length to adjust the opening size of the air exhaust passage 51b.

이때, 공기배출로(51b)가 형성되고 감압조절수단(53)이 설치되는 몸체(51)의 상부는 도면과 같이 캡 형태로 만들어져 몸체(51)에 탈착되게 설치될 수 있음을 밝혀둔다.At this time, the upper portion of the body 51, the air discharge path 51b is formed and the decompression control means 53 is installed is made in the form of a cap as shown in the figure can be installed detachably to the body 51.

한편, 몸체(51)의 중간에는 연락공(51a)으로부터 유입되는 저장탱크(25)의 공기를 필터링하기 위한 필터부재(55)가 설치됨이 바람직하고, 공기배출로(51b)의 중간에는 배출되는 공기로부터 발생하는 소음 즉, 공기가 좁은 구멍을 통과함으로써 발생하는 소음을 흡음하기 위한 흡음부재(57)가 설치됨이 바람직하다.On the other hand, in the middle of the body 51 is preferably provided with a filter member 55 for filtering the air in the storage tank 25 introduced from the contact hole (51a), and is discharged in the middle of the air discharge path (51b) Preferably, a sound absorbing member 57 is provided for absorbing the noise generated from the air, that is, the noise generated by passing the air through the narrow hole.

또한, 몸체(51)에는 연락공(51a)을 통해서 응축수가 몸체(51)의 내부로 유입되는 것을 차단하기 위한 응축수유입 차단수단(59)이 설치됨이 바람직하다. 예컨대, 배출구(23)의 크기를 좁게 형성한 이유 등으로 인해서 저장탱크(25)로의 응축수 유입량이 배출량보다 크면, 저장탱크(25)에 가득 찬 응축수가 연락공(51a)을 통해서 몸체(51)의 내부로 유입될 수 있는데, 응축수유입 차단수단(59)은 이의 유입을 차단하여 감압수단(50)을 보호한다.In addition, the body 51 is preferably provided with condensate inlet blocking means 59 for blocking condensate from entering the interior of the body 51 through the contact hole (51a). For example, if the inflow of the condensate into the storage tank 25 is larger than the discharge due to the reason for narrowly forming the size of the outlet 23, the condensed water filled in the storage tank 25 is filled through the communication hole 51a. It may be introduced into the condensate inflow blocking means 59 to block the inflow thereof to protect the decompression means (50).

즉 도 4에 도시된 바와 같이, 몸체(51)의 하부에는 격벽(59a)의 구멍(59b)을 통해서 몸체(51)의 내부와 연락하는 격실(59c)를 형성하고, 그 격실(59c)의 내부에는 제1부구(59d)를 설치하여, 연락공(51a)을 통해 응축수가 격실(59c)로 유입되면, 제1부구(59d)가 수위를 따라 상승해 구멍(59b)을 막음으로써, 몸체(51)의 내부로 응축수가 유입되는 것을 차단한다.That is, as shown in Figure 4, the lower portion of the body 51 through the hole 59b of the partition wall 59a to form a compartment 59c in contact with the interior of the body 51, and the When the first part 59d is provided inside, and the condensed water flows into the compartment 59c through the communication hole 51a, the first part 59d rises along the level to block the hole 59b. The condensate is blocked from entering 51.

이때 제1부구(59d)는 무게가 매우 가볍기 때문에, 저장탱크(25)의 공기가 연 락공(51a)을 통해서 빠져 나가는 일을 방해하지 않는다. 즉 제1부구(59d)는 저장탱크(25)의 공기압이, 높이가 낮을지라도 충분히 들어올릴 수 있는 무게로 설계되어 있기 때문에, 저장탱크(25)의 공기가 연락공(51a)을 통해서 빠져 나가는 일을 방해하지 않는다.At this time, since the first portion 59d is very light, the air of the storage tank 25 does not prevent the air from escaping through the contact hole 51a. That is, since the first portion 59d is designed to have a sufficient weight to lift the air pressure of the storage tank 25 even when the height is low, the air of the storage tank 25 escapes through the contact hole 51a. Does not interfere with work
