본 고안은 도료 도포용 노즐에 관한 것이다.The present invention relates to a nozzle for coating a coating.
도료도포용 노즐은 도포하고자 하는 도료의 특성에 따라 여러 종류의 것이 있는데, 통상적인 노즐의 일 예를 제1도에 나타내 보였다.There are various types of nozzles for coating the coating according to the characteristics of the coating to be applied. An example of a conventional nozzle is shown in FIG.
이것은 중공부(2a)를 가지며 그 주면에 나사부(2b)가 형성된 본체(2)와, 상기 본체(2)의 일측면에 접촉되며 상기 중공부(2a)와 연통되는 관통공(3a) 및 교축부(3b)를 가지는 노즐부재(3)와, 상기본체(2)의 단부(2c)와 노즐부재(3) 사이에 개재되는 복수개의 링형 패킹부재(4)와, 상기 본체(2)와 나사결합되어 상기 패킹부재(4) 및 노즐부재(3)를 본체(2)의 단부(2c)즉, 상기 중공부 가장자리에 밀착시키는 캡(5)을 구비하여 구성된다.It has a hollow portion 2a and a main body 2 having a screw portion 2b formed on its main surface, a through hole 3a and a bridge contacting one side surface of the main body 2 and communicating with the hollow portion 2a. A nozzle member 3 having a shaft portion 3b, a plurality of ring-shaped packing members 4 interposed between the end portion 2c of the main body 2 and the nozzle member 3, the main body 2 and the screw It is configured to have a cap (5) coupled to the packing member 4 and the nozzle member 3 in close contact with the end (2c) of the main body 2, that is to say the edge of the hollow portion.
이와같이 구성된 종래 도료 도포용 노즐(1)은 상기 캡(5)과 본체(2)가 나사결합 됨으로써 상기 노즐부재(3)와 패킹부재(4)를 본체(2)의 중공부(2a) 가장자리에 밀착접촉 시키게 되므로 상기 패킹부재(4)가 상기 중공부(2a)의 가장자리와 상기 노즐부재(3)의 관통공(3a) 가장자리로부터 그들의 중심방향으로 소정길이 돌출되게 된다. 특히, 상기 본체(2)의 중공부(2a) 가장자리에는 패킹부재(4)의 밀착시 이의 위치를 고정할 수 있는 고정부가 마련되어 있지 않으므로 조립시 패킹부재(4)가 상기와 같이 중공부(2a) 및 관통공(3a)의 가장자리로부터 돌출되게 되면 상기 중공부(2a) 및 관통공(3a)을 매우 빠른 유속으로 통과하여 노즐부재(3)의 교축부(3b)로부터 분사되는 도료에는 많은 기포가 발생하게 된다. 즉, 상기 패킹부재(4)가 상기 중공부(2a) 및 관통공(3a) 가장자리로부터 중심부로 소정길이 돌출되어 있으므로 돌출된 패킹부재(4)의 배면(제1b도의 A부분)주위가 도료의 유속에 의해 압력이 낮아지는 캐비테이션 현상에 의해 기포가 발생하게 된다.In the conventional paint coating nozzle (1) configured as described above, the cap (5) and the main body (2) are screwed together so that the nozzle member (3) and the packing member (4) are formed at the edge of the hollow portion (2a) of the main body (2). Since the packing member 4 is in close contact, the packing member 4 protrudes a predetermined length from the edge of the hollow part 2a and the edge of the through hole 3a of the nozzle member 3 in the direction of their center. In particular, since the fixing part for fixing the position of the packing member 4 is not provided at the edge of the hollow part 2a of the main body 2, the packing member 4 is assembled with the hollow part 2a as described above. And protruding from the edge of the through hole 3a, many bubbles are formed in the paint sprayed from the throttle portion 3b of the nozzle member 3 through the hollow portion 2a and the through hole 3a at a very high flow rate. Will occur. That is, since the packing member 4 protrudes a predetermined length from the edge of the hollow part 2a and the through hole 3a to the center part, the periphery of the back surface (part A of FIG. 1b) of the protruding packing member 4 is formed of Bubbles are generated by the cavitation phenomenon in which the pressure decreases due to the flow rate.
따라서 도포되는 도료에 기포가 포함됨으로써 도포불량이 야기 되게 되는 문제점이 있었다.Therefore, there is a problem that the coating is caused by the inclusion of air bubbles in the coating applied.
본 고안은 상기 문제점을 해결하기 위하여 안출된 것으로서, 그 자체에서의 기포발생원인을 근본적으로 해결하여 도료의 도포불량을 방지할 수 있는 도료 도포용 노즐을 제공함에 그 목적이 있다.The present invention has been made to solve the above problems, it is an object of the present invention to provide a paint coating nozzle that can fundamentally solve the cause of bubbles in itself to prevent the coating failure of the paint.
상기 목적을 달성하기 위하여 본 고안은, 중공부를 가지는 본체와, 상기 본체의 단부에 접촉되며 상기 중공부와 대략 동일직경의 관통공을 가지는 노즐부재와, 상기 본체와 노즐부재사이에 개재되는 복수개의 패킹부재와, 상기 본체와 나사결합되어 패킹부재와 노즐부재를 상기 단부 밀착시키는 캡을 구비하여 된 도료 도포용 노즐에 있어서, 상기 본체에 그 중공부 가장자리로부터 축방향으로 연장되어 외주면에 상기 패킹부재가 삽입되는 패킹지지부를 형성하고, 상기 노즐부재에는 상기 패킹지지부가 삽입되는 결합부를 형성하여, 이들의 결합시 패킹부재가 상기 중공부 및 관통공의 가장자리로부터 중심방향으로 돌출되지 않도록 한 것을 특징으로 한다.In order to achieve the above object, the present invention, a main body having a hollow portion, a nozzle member in contact with the end of the main body and having a through hole of approximately the same diameter as the hollow portion, and a plurality of interposed between the main body and the nozzle member A coating material nozzle comprising a packing member and a cap screwed with the main body to bring the packing member and the nozzle member into close contact with each other, wherein the main body extends in an axial direction from an edge of the hollow part of the main body to the packing member. And a packing supporting part into which the packing support is inserted, and a coupling part into which the packing supporting part is inserted is formed in the nozzle member so that the packing member does not protrude in the center direction from the edge of the hollow part and the through hole when they are combined. do.
이하 첨부된 도면을 참조하여 본 고안에 따른 한 바람직한 실시예를 상세하게 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
제2도에는 본 고안에 따른 도료 도포용 노즐(10)을 나타내 보였다. 이것은 본체(11)의 중심축선상에 중공부(11b)가 형성되고 상기 본체(11)의 외주면에는 나사부(11c)가 형성된다. 그리고 상기 본체(11)의 중공부(11b) 가장자리에는 이로부터 소정길이 연장되어 그 외주에 복수개의 패킹부재(12)가 삽입되는 대략 원통형상의 패킹지지부(11a)가 형성된다.Figure 2 shows a paint coating nozzle 10 according to the present invention. The hollow part 11b is formed in the center axis line of the main body 11, and the thread part 11c is formed in the outer peripheral surface of the main body 11. As shown in FIG. In addition, a substantially cylindrical packing support portion 11a is formed at an edge of the hollow portion 11b of the main body 11 so that a predetermined length thereof extends and a plurality of packing members 12 are inserted in the outer circumference thereof.
그리고 상기 본체(11)와 결합되는 노즐부재(13)는 상기 패킹지지부(1a)가 삽입되는 결합부(13a)가 형성되고 상기 중공부(11b)와 대략 동일직경의 관통공(13b)이 형성되며 상기 관통공(13b)의 단부에는 교축부(13c)가 형성된다. 그리고 상기 노즐부재(13)를 본체(11)를 본체(11)에 밀착시키는 캡(15)은 그 단부 가장자리로부터 중심방향으로 소정길이 연장되어 상기 노즐부재(13)의 외주의 일측면과 접촉되는 플랜지부(15a)가 형성되고 그 내부면에는 상기 본체(11)의 나사부(11c)와 결합되는 나사부(15b)가 형성된다.The nozzle member 13 coupled to the main body 11 includes a coupling part 13a into which the packing support part 1a is inserted, and a through hole 13b having a diameter substantially the same as that of the hollow part 11b. At the end of the through hole 13b, a throttle portion 13c is formed. In addition, the cap 15 which adheres the nozzle member 13 to the main body 11 to the main body 11 extends a predetermined length from the end edge thereof in the center direction to contact one side surface of the outer circumference of the nozzle member 13. A flange portion 15a is formed, and an inner surface thereof has a thread portion 15b coupled to the threaded portion 11c of the main body 11.
이와같이 구성된 본 고안에 따른 도료 도포용 노즐(10)은 복수개의 패킹부재(13)가 삽입된 상기 본체(11)의 패킹지지부(11a)를 노즐부재(13)의 결합부(13a)에 삽입하고 상기 캡(15)을 상기 본체(11)와 나사결합 함으로써 결합되게 되는데, 상기 패킹부재(12)가 패킹지지부(11a)의 외주면에 삽입지지되어 본체(11)의 패킹지지부(11a) 주위와 노즐부재(13)의 단부사이에 개재되게 되므로 종래와 같이 패킹부재(12)가 도료의 통로인 본체(11)의 중공부(11b)와 노즐부재(13)의 관통공(13b)의 가장자리로부터 중심부측으로 돌출되는 것을 방지할 수 있다. 따라서, 도료가 상기 노즐(10)의 중공부(11b) 및 관통공(13b)을 통과하는 동안에 기포가 발생하는 것을 방지할 수 있게 된다.The paint coating nozzle 10 according to the present invention configured as described above inserts the packing support part 11a of the main body 11 into which the plurality of packing members 13 are inserted into the coupling part 13a of the nozzle member 13. The cap 15 is coupled to the main body 11 by screwing, and the packing member 12 is inserted into and supported on the outer circumferential surface of the packing supporting part 11a, and around the packing supporting part 11a of the main body 11 and the nozzle. Since it is interposed between the ends of the member 13, the packing member 12 is centered from the edge of the hollow portion 11b of the main body 11, which is a passage for the paint, and the through hole 13b of the nozzle member 13, as in the conventional art. Protruding to the side can be prevented. Accordingly, bubbles can be prevented from occurring while the paint passes through the hollow portion 11b and the through hole 13b of the nozzle 10.
이와같이 본 고안 도료 도포용 노즐은 본체와 패킹 부재사이에 개재되는 패킹부재가 도료의 통로인 중공부 및 관통공으로 돌출되지 않게 되어 종래와 같이 기포발생 원인을 근본적으로 해결하여 기포발생에 의한 도포 불량을 방지할 수 있으며, 도료의 관내이동에 따른 관내손실을 대폭 줄일 수 있는 이점이 있다.In this way, the coating material nozzle of the present invention prevents the packing member interposed between the main body and the packing member from protruding into the hollow part and the through hole, which is a passage of the paint, thereby fundamentally solving the cause of bubble generation and preventing coating failure due to bubble generation. It can prevent, and there is an advantage that can significantly reduce the loss in the pipe due to the movement of the pipe in the pipe.
