본 고안은 역삼투압 밸브조립체, 특히 역삼투압을 이용한 정수기에 사용되는 역삼투압 밸브조립체에 관한 것이다.The present invention relates to a reverse osmosis valve assembly, in particular a reverse osmosis valve assembly used for a water purifier using a reverse osmosis.

최근 정수기 기술분야에서는 정수효율이 가장 우수하다고 판명된 소위 역삼투압 정수기가 주목을 받고 있다. 이 역삼투압정수기라 함은 상대적으로 고농도인 원수(정수전의 물)에 압력을 가하여 삼투막을 통과시킴으로써 상대적으로 저농도인 정수를 얻는 장치이다.Recently, the so-called reverse osmosis water purifier, which has been found to have the best water purification efficiency in the water purifier technology field, has attracted attention. This reverse osmosis water purifier is a device that obtains a relatively low concentration of purified water by passing pressure through relatively high concentration of raw water (water before water purification) and passing through the osmosis membrane.

위와 같은 역삼투압정수기의 원수에 압력을 가해주기 위해서는, 상류측유로를 흐르는 물의 양이 일정한 경우에는, 하류측유로를 흐르는 물의 양을 소량으로 제한해주면 될 것이다.In order to apply pressure to the raw water of the reverse osmosis water purifier as described above, if the amount of water flowing in the upstream side flow is constant, the amount of water flowing in the downstream side flow passage may be limited to a small amount.

한편, 위와 같은 역삼투압정수기를 분해하지 않고 청소하기 위해서는 원수를 역삼투압정수기내에 고속으로 통과시켜주면 정수기 내에 침착된 이물질을 수압에 의해 제거하는 것이 가능할 것이다.On the other hand, in order to clean the reverse osmosis water purifier without disassembly as described above, if the raw water is passed through the reverse osmosis water purifier at high speed, it will be possible to remove foreign substances deposited in the water purifier by water pressure.

본 고안은 위와 같은 개념하에 안출된 것으로서, 본 고안의 목적은 역삼투압정수기의 하류측의 유량을 소량으로 제한하여 정수기 내에 고압이 걸리게 함으로써 원수가 삼투막을 통과할 수 있게 하고, 반면에 정수기 내부를 청소하고자 할때는 정수기의 하류측의 유량을 증가시켜 고소으로 유동하는 다량의 원수가 삼투막을 통과함이 없이 삼투막의 표면 및 정수기 내벽에 부착된 이물질을 제거할 수 있도록 유량조절이 가능한 역삼투압 밸브조립체를 제공하는 것이다.The present invention is conceived under the same concept as above, the object of the present invention is to limit the flow rate of the reverse osmosis water purifier to a small amount to allow high pressure in the water purifier to allow the raw water to pass through the osmosis membrane, while on the other hand When cleaning, increase the flow rate on the downstream side of the water purifier and increase the flow rate of the reverse osmosis valve assembly that can control the flow rate to remove the foreign matter attached to the surface of the osmosis membrane and the inner wall of the water purifier without passing through the osmosis membrane To provide.

위와 같은 목적을 달성하기 위해 본 고안에서는, 상류측유로, 이 상류측유로의 동일축선상에 형성된 하류측유로, 및 이 상하류측유로 사이에 이들 유로에 수직하게 형성된 원형단면의 샤프트삽입공을 구비한 밸브몸체; 및 그 상부에 형성된 유량조절용 회전노브, 이 회전노브를 일방향으로 회전시켰을 때 상기 상하류측유로와 연통하여 상기 하류측유로의 유량을 제한할 수 있는 그 축방향에 수직하게 형성된 소직경유로, 및 상기 회전노브를 타방향으로 회전시켰을 때 상기 상하류측유로와 연통하여 상기 하류측유로의 유량을 다량으로 조절할 수 있는 상기 소직경유로에 수직하게 형성된 대직경유로를 구비한, 상기 샤프트삽입공에 회전운동이 가능하게 삽입되는 원통상 샤프트를 포함하는 것을 특징으로 하는 역삼투압 밸브조립체를 제공한다.In order to achieve the above object, the present invention provides an upstream side passage, a downstream side passage formed on the same axis of the upstream side passage, and a shaft insertion hole of a circular cross section formed perpendicular to these flow passages between the upstream and downstream side passages. One valve body; And a flow regulating rotary knob formed at an upper portion thereof, a small diameter passage formed perpendicularly to the axial direction thereof in communication with the upstream and downstream side passages when the rotary knob is rotated in one direction to limit the flow rate of the downstream side passages, and the Rotating movement in the shaft insertion hole, having a large diameter passage perpendicular to the small diameter passage that can communicate with the upstream and downstream side passages when the rotary knob is rotated in the other direction to adjust the flow rate of the downstream side passage in a large amount. It provides a reverse osmosis valve assembly comprising a cylindrical shaft which is possibly inserted.

이하, 첨부한 도면을 참고하여 본 고안의 일실시예에 대하여 상세히 설명한다.Hereinafter, with reference to the accompanying drawings will be described in detail an embodiment of the present invention.

제1도는 본 고안의 일실시예에 따른 역삼투압 밸브조립체(10)의 소직경유로(14a)가 그 상류측유로(U)및 하류측유로(D)에 개방된 상태를 보여주는 측단면도이고, 제2도는 대직경유로(14b)가 개방된 상태를 보여주는 측단면도이다.1 is a side cross-sectional view showing a state in which the small diameter passage 14a of the reverse osmosis valve assembly 10 according to an embodiment of the present invention is opened in the upstream side passage U and the downstream side passage D, 2 is a side cross-sectional view showing a state where the large diameter passage 14b is opened.

위 양 도면에 도시되어 있는 바와 같이, 본 고안의 일 실시예에 따른 역사투압 밸브조립체(10)는 상류측유로(U) 및 이 상류측유로(U)의 동일축선상에 형성된 하류측유로(D)를 포함하는 밸브몸체(11)를 포함한다. 이 밸브몸체(11)의 중앙부, 즉 상기 상류측유로(U)와 하류측유로(D) 사이에는 이들양 유로(U)(D)에 수직한 방향의 삽입공(12)이 형성되어 있다.As shown in both figures, the reverse osmosis valve assembly 10 according to an embodiment of the present invention is the upstream side flow path (U) and the downstream side flow path formed on the same axis of the upstream side flow path (U) ( And a valve body 11 including D). An insertion hole 12 in a direction perpendicular to the two flow paths U and D is formed between the central portion of the valve body 11, that is, the upstream side flow path U and the downstream side flow path D. FIG.

상기 삽입공(12)내에는 원통상 샤프트(14)가 회전운동이 가능하게 삽입되어 있다. 이 샤프트(14)의 상부에는 유량조절용 회전노브(13)이 형성되어 있으며, 이 회전노브(13)의 외주면에는 널링가공표면(13a)이 형성되어 있다.The cylindrical shaft 14 is inserted into the insertion hole 12 to enable the rotational movement. A flow regulating rotary knob 13 is formed on the top of the shaft 14, and a knurled machining surface 13a is formed on the outer circumferential surface of the rotary knob 13.

또한, 상기 회전노브(13)의 샤프트(14)의 중간부에는 상기 회전노브(13)를 일방향으로 회전시켰을 때 상기 상하류측유로(U)(D)와 연통하도록 된 소직경유로(14a)가 형성되어 있으며, 이 소직경유로(14a)에 직각방향에는 상기 회전노브(13)를 타방향으로 회전시켰을 때 상기 상하류측유로(U)(D)와 연통하도록 된 대직경유로(14b)가 형성되어 있다. 따라서, 상기 소직경유로(14a)로가 상기 상하류측유로(U)(D)와 연통된 경우에는 하류측유로(D)의 유량이 소량으로 제한됨으로써 역삼투압정수기(도시생략) 내에 고압이 걸리게 되며, 당기 대직경유로(14b)가 상기 상하류측유로(U)(D)와 연통된 경우에는 하류측유로(D)의 유량이 상류측유로(U)와 동일하게 유지됨으로써 역삼투압정수기 내의 원수는 삼투막을 통과함이 없이 삼투막표면 및 정수기 내벽면을 고속으로 휩쓸고 지나가게 됨으로써 삼투막 및 정수기 내벽면에 부착된 이물질을 제거할 수 있게 된다.In addition, a small diameter passage 14a is formed at an intermediate portion of the shaft 14 of the rotary knob 13 so as to communicate with the upstream and downstream side passages U and D when the rotary knob 13 is rotated in one direction. The large diameter channel 14b is formed in a direction perpendicular to the small diameter channel 14a so as to communicate with the upstream and downstream side channels U and D when the rotary knob 13 is rotated in the other direction. It is. Therefore, when the small diameter passage 14a communicates with the upstream and downstream side passages U and D, the flow rate of the downstream side passage D is limited to a small amount so that a high pressure is applied to the reverse osmosis water purifier (not shown). When the large diameter flow passage 14b is in communication with the upstream and downstream flow passages U and D, the flow rate of the downstream flow passage D remains the same as the upstream flow passage U, thereby preventing the raw water in the reverse osmosis water purifier. By sweeping through the osmosis membrane surface and the inner wall of the water purifier at high speed without passing through the osmosis membrane, it is possible to remove the foreign matter attached to the osmosis membrane and the inner wall of the water purifier.

또한, 원통상 샤프트(14)의 상하단부 각각에는 이 원통상 샤프트(14)와 그 삽입공(12) 사이에 형성된 미세한 틈새를 기밀유지하기 위한 고무재질의 상부시일(15a) 및 하부시일(15b)이 설치되어 있다. 또한 제1도에 잘 나타나 있는 바와 같이, 상기 샤프트(14)에 형성된 소직경유로(14a)의 입구 주변에는 고무재질의 측면시일(15c) 이 설치되어 있다. 이와 같은 구성에 의해, 제1도에 도시한 바와 같이, 소직경유로(14a)가 개방된 상태에서 상류측유로(U)의 정수는 소직경유로(14a)만을 통해 하류측유로(D)로 유동하게 된다.In addition, each of the upper and lower ends of the cylindrical shaft 14 has an upper seal 15a and a lower seal 15b made of rubber material for hermetically keeping minute gaps formed between the cylindrical shaft 14 and the insertion hole 12. ) Is installed. As well shown in FIG. 1, a rubber side seal 15c is provided around the inlet of the small diameter passage 14a formed in the shaft 14. By such a configuration, as shown in FIG. 1, the constant of the upstream side flow path U in the state where the small diameter flow path 14a is opened is passed to the downstream side flow path D only through the small diameter flow path 14a. Will flow.

위 양 도면에서 설명되지 않은 참조번호 16은 상기 샤프트(14)의 상부를 회전지지하는 상부걸림턱을 나타내며, 참조번호 17은 상기 샤프트(14)의 하부를 회전지지하는 지지링을 나타낸다.Reference numeral 16, which is not described in both figures, indicates an upper locking jaw supporting the upper portion of the shaft 14, and reference numeral 17 denotes a support ring for supporting the lower portion of the shaft 14.

이하, 본 고안의 작용 및 효과에 대하여 설명한다.Hereinafter, the operation and effects of the present invention will be described.

먼저, 제1도에 도시한 바와 같이 상기 유량조절용 회전노브(13)를 일방향으로 회전시키면, 상기 밸브조립체(10)의 상류측유로(U)의 물은 이 상류측유로(U)의 관경에 비해 상대적으로 관경이 작은 샤프트(14)에 형성된 소직경유로(14a)를 통해 하류측유로(D)로 이동하게 되므로 상기 상류측유로(U)에는 높은 수압이 걸리게 되고, 이에 따라 도시되지 않은 역삼투압정수기 내의 원수는 삼투막을 통과할 수 있게 되어 역삼투압방식의 정수가 이루어진다.First, as shown in FIG. 1, when the flow control rotary knob 13 is rotated in one direction, the water of the upstream side flow path U of the valve assembly 10 reaches the diameter of the upstream side flow path U. Compared to the downstream side flow path (D) through the small diameter flow path (14a) formed in the shaft 14 having a relatively small diameter, the upstream side flow path (U) is subjected to high water pressure, and thus not shown The raw water in the osmotic water purifier is allowed to pass through the osmosis membrane, thereby forming a reverse osmosis water purification.

반면에, 제2도에 도시한 바와 같이 상기 유량조절용 회전노브(13)를 타방향으로 회전시키면, 상기 밸브조립체(10)의 상류측유로(U)의 물은 이 상류측유로(U)의 관경과 동일한 관경의 대직경유로(14a)를 통해 하류측유로(D)로 이동하게 되므로 상기 상류측유로(U)에는 수압이 걸리지 않게 된다. 따라서, 도시되지 않은 역삼투압정수기내의 원수는 정수용 삼투막을 통과할 수 없고 삼투막의 표면 및 정수기 내벽면을 휩쓸고 지나감으로써 이물질을 제거할 수 있게 된다. 따라서, 이 정수기를 분해하지 않고도 정수기 내부를 청소할 수 있게된다.On the other hand, as shown in FIG. 2, when the flow control rotary knob 13 is rotated in the other direction, the water of the upstream side flow path U of the valve assembly 10 is discharged from the upstream side flow path U. Since it moves to the downstream side flow path D through the large diameter flow path 14a of the same diameter as the diameter, the upstream side flow path U is not subjected to water pressure. Therefore, the raw water in the reverse osmosis water purifier (not shown) cannot pass through the osmosis membrane for water purification and can remove foreign substances by sweeping the surface of the osmosis membrane and the inner wall surface of the water purifier. Therefore, the inside of the water purifier can be cleaned without disassembling the water purifier.

이상은 본 고안의 특정실시예에 대한 설명에 불과하며, 본 고안은 그 구성요지의 범위 내에서 다양한 변경 및 개조가 가능하다.The above is only a description of a specific embodiment of the present invention, the present invention is capable of various changes and modifications within the scope of the configuration.
