이하, 본 발명의 구체적인 실시 예를 첨부 도면을 참조하여 상세히 살펴보기로 한다.Hereinafter, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings.

본 발명의 실시 예는 여러 가지 형태로 변형될 수 있으며, 본 발명의 범위가 아래에서 상세히 설명하는 실시 예로 한정되는 것으로 해석되어서는 안 된다. 본 실시 예는 당 업계에서 평균적인 지식을 가진 자에게 본 발명을 더욱 완전하게 설명하기 위하여 제공되는 것이다.The embodiments of the present invention may be modified in various forms, and the scope of the present invention should not be construed as being limited to the embodiments described in detail below. This embodiment is provided to more completely describe the present invention to those with average knowledge in the industry.

따라서, 도면에서 표현한 구성요소의 형상 등은 더욱 명확한 설명을 강조하기 위해서 과장되어 표현될 수 있다. 각 도면에서 동일한 구성은 동일한 참조부호로 도시한 경우가 있음을 유의하여야 한다. 또한, 본 발명의 요지를 불필요하게 흐릴 수 있다고 판단되는 공지 기술의 기능 및 구성에 관한 상세한 설명은 생략될 수 있다.Accordingly, the shape of the constituent elements expressed in the drawings may be exaggerated to emphasize a more clear description. It should be noted that in each drawing, the same configuration may be indicated by the same reference numeral. In addition, detailed descriptions of functions and configurations of known technologies determined to unnecessarily obscure the subject matter of the present invention may be omitted.

먼저, 본 발명의 일 실시 예에 따른 분무 라인용 드레인 노즐의 구성을 도 1 내지 도 7을 통해 살펴보면 다음과 같다.First, a configuration of a drain nozzle for a spray line according to an embodiment of the present invention will be described with reference to FIGS. 1 to 7.

본 실시 예에서의 배관라인(100)에는 다수의 분무노즐(10)이 일정 간격으로 연결되어 있는 가운데, 일측에는 드레인 노즐(20)과 조절밸브(30) 및 펌프(40)가 직렬 형태로 연결된 것을 도 1을 통해 확인할 수 있다.In this embodiment, a plurality of spray nozzles 10 are connected to the piping line 100 at regular intervals, and at one side, the drain nozzle 20, the control valve 30, and the pump 40 are connected in series. This can be confirmed through FIG. 1.

이때, 상기 드레인 노즐(20)은 도 2에서와같이 배관라인(100)과 연결이 이루어지는 노즐본체(21)와, 상기 노즐본체(21)의 일단부에 나사 체결 방식으로 착탈 가능하게 연결이 이루어지는 배출캡(22)으로 구성된다.At this time, the drain nozzle 20 is a nozzle body 21 connected to the piping line 100 as shown in FIG. 2 and detachably connected to one end of the nozzle body 21 by a screw fastening method. It consists of a discharge cap (22).

상기 배출캡(22)에는 배출공(22a)이 중앙에 관통 형성된 구조를 이루는 가운데, 노즐본체(21) 내부에는 유로의 개폐를 위한 금속 재질의 개폐볼(23)이 구비되고, 상기 개폐볼(23)의 일측을 탄성 지지하는 제1스프링(24)과, 상기 개폐볼(23)의 타측을 탄성 지지하는 제2스프링(25)의 구성을 이루는 것을 도 3 및 도 4의 단면도를 통해 확인할 수 있다.The discharge cap 22 has a structure formed with a discharge hole 22a penetrating through the center, and an opening and closing ball 23 made of a metal material for opening and closing a flow path is provided inside the nozzle body 21, and the opening and closing ball ( It can be seen through the cross-sectional views of FIGS. 3 and 4 that the first spring 24 elastically supports one side of 23) and the second spring 25 elastically supports the other side of the opening/closing ball 23. have.

특히, 노즐본체(21)와 배출캡(22)에는 각각 암나사산과 수나사산이 형성되어져 있어서 상호간에 나사체결이 이루어지게 되는데, 배출캡(22) 부위에는 도 5의 확대도에서와 같이 제2스프링(25)이 안착되는 스프링 안착홈(22b)이 형성되며, 배출공(22a) 일측에는 개폐볼(23)의 안착을 위한 볼안착부(22c)가 테이퍼면을 이루어 형성된다.In particular, the nozzle body 21 and the discharge cap 22 are each formed with a female thread and a male thread, so that screwing is made to each other. The discharge cap 22 has a second spring as shown in the enlarged view of FIG. 5. The spring seating groove 22b on which the 25 is seated is formed, and a ball seating portion 22c for seating the opening and closing ball 23 is formed on one side of the discharge hole 22a to form a tapered surface.

도면 중 미설명 부호 22d는 기밀성을 위해 링 형태를 이루는 고무패킹을 나타낸다.In the drawings, unexplained reference numeral 22d denotes a rubber packing in a ring shape for airtightness.

이와 같은 구성을 이루는 본 발명 분무 라인용 드레인 노즐의 동작에 따른 작용효과를 도 8 및 도 9를 통해 살펴보기로 한다.The effect of the operation of the drain nozzle for a spray line according to the present invention having such a configuration will be described with reference to FIGS. 8 and 9.

본 발명에서의 드레인 노즐(20)은 평상시에는 도 3에서와같이 내부의 개폐볼(23)이 양측 제1스프링(24)과 제2스프링(25)의 탄성 지지력에 의해 지지되면서 내부 유로가 개방된 상태를 이루게 된다.In the drain nozzle 20 in the present invention, as shown in FIG. 3, the inner flow path is opened while the inner opening and closing balls 23 are supported by the elastic support force of the first and second springs 24 and 25 on both sides. Will achieve the state.

이러한 상태에서 펌프(40)를 구동시킴과 함께 조절밸브(30)를 열어주게 되면 배관라인(100)을 통해 물공급이 이루어지게 된다.In this state, when the pump 40 is driven and the control valve 30 is opened, water is supplied through the piping line 100.

즉, 물공급 초기에는 배관라인(100) 내부의 유속 및 압력이 낮은 상태에서 서서히 상승하게 되는데, 일정 압력 이상으로 상승하기 전까지는 약한 수압으로 인해 도 6에서와같이 개폐볼(23)의 유동이 발생되지 않는 개방 상태를 이루기 때문에 드레인 노즐(20)을 통하여 물이 배출되면서 분무노즐(10)을 통한 워터드롭 현상이 방지될 수 있게 된다.That is, at the beginning of water supply, the flow rate and pressure inside the piping line 100 are gradually increased while the flow rate and pressure inside the pipe line 100 are low, but the flow of the opening/closing ball 23 as shown in FIG. 6 due to weak water pressure until it rises above a certain pressure Since water is discharged through the drain nozzle 20, the water drop phenomenon through the spray nozzle 10 can be prevented.

한편, 점차 수압이 상승하여 일정 압력 이상이 되게 되면 도 7에서와같이 수압 작용으로 인해 개폐볼(23)이 배출캡(22)의 스프링 안착홈(22b)에 안착되면서 배출공(22a)을 막는 폐쇄 상태를 이루어서 더이상 물 배출이 발생되지 않는 가운데 분무노즐(10)을 통한 분무 동작이 이루어지게 된다.On the other hand, when the water pressure gradually rises to become more than a certain pressure, as shown in FIG. 7, the opening and closing ball 23 is seated in the spring seating groove 22b of the discharge cap 22, thereby blocking the discharge hole 22a. A spray operation is performed through the spray nozzle 10 while the water is no longer discharged due to the closed state.

그리고, 분무 동작을 종료시키기 위해 조절밸브(30)를 닫아주게 되면 배관라인(100)의 내부 수압이 서서히 낮아지게 되는데, 이때에는 드레인 노즐(20)에 전해지는 수압이 떨어짐과 함께 제2스프링(25)의 탄성작용으로 인해 도 6에서와같이 다시 개폐볼(23)이 중단으로 이동되면서 유로 개방이 이루어지게 되어 배관라인(100)에 남아있던 잔압 및 잔수 배출이 이루어지게 된다.In addition, when the control valve 30 is closed to terminate the spraying operation, the internal water pressure of the piping line 100 is gradually lowered. In this case, the water pressure transmitted to the drain nozzle 20 drops and the second spring ( Due to the elastic action of 25), as the opening/closing ball 23 moves to the middle as shown in FIG. 6, the flow path is opened, and residual pressure and residual water remaining in the piping line 100 are discharged.

따라서 본 발명의 드레인 노즐은, 분무동작의 시작 및 종료 순간 분사노즐을 통한 워터드롭 현상을 방지하고, 분무동작 종료 후 배관라인 내부에 남아있는 잔압 및 잔수가 신속하게 제거될 수 있게 되어 배관 내부 오염 및 동절기 동파를 효율적으로 방지하는 효과를 나타낸다.Therefore, the drain nozzle of the present invention prevents the water drop phenomenon through the spray nozzle at the moment of the start and end of the spraying operation, and can quickly remove residual pressure and residual water remaining inside the piping line after the spraying operation is finished, so that the inside of the pipe is contaminated. And it shows the effect of effectively preventing freeze in winter.

한편, 도 10은 본 발명의 다른 실시 예에 따른 구성을 나타낸 것으로서, 상기 볼안착부(22c)에는 실리콘 수지, 아크릴산 수지, 에폭시 레진, 셀룰로오스, 벤토나이트, 카본블랙 성분의 혼합 조성을 이루는 밀착 코팅층(22e)이 코팅 형성되어지게 되며, 기능성 향상을 위해서는 폴리메틸비닐실록산수지, 지르코늄디옥사이드 성분이 추가로 첨가될 수 있다.On the other hand, Figure 10 shows the configuration according to another embodiment of the present invention, the ball seating portion (22c) is a contact coating layer (22e) forming a mixture composition of silicone resin, acrylic acid resin, epoxy resin, cellulose, bentonite, and carbon black components. ) Is formed as a coating, and polymethylvinylsiloxane resin and zirconium dioxide components may be additionally added to improve functionality.

즉, 이때에는 실리콘 수지 20~40중량%, 아크릴산 수지 20~40중량%, 에폭시 레진 10~30중량%, 셀룰로오스 10~20중량%, 벤토나이트 1~10중량%, 카본블랙 1~10중량%, 폴리메틸비닐실록산수지 1~5중량%, 지르코늄디옥사이드 1~5중량%의 비율로 혼합이 이루어짐이 바람직하다.That is, at this time, silicone resin 20 to 40% by weight, acrylic acid resin 20 to 40% by weight, epoxy resin 10 to 30% by weight, cellulose 10 to 20% by weight, bentonite 1 to 10% by weight, carbon black 1 to 10% by weight, It is preferable that the mixture is made in a ratio of 1 to 5% by weight of polymethylvinylsiloxane resin and 1 to 5% by weight of zirconium dioxide.

이와 같은 성분의 밀착 코팅층(22e)이 볼안착부(22c)에 박막으로 코팅 형성되어지게 되면, 개폐볼(23)과의 밀착력이 향상되어 안정적인 수밀성이 유지될 수 있게 된다.When the adhesion coating layer 22e of such a component is formed as a thin film on the ball seating portion 22c, the adhesion with the opening and closing ball 23 is improved, so that stable watertightness can be maintained.

특히, 밀착 코팅층(22e)에는 열 가소성의 아크릴산 수지가 혼합되어 있기 때문에 볼안착부(22c)의 부착력을 증대시키고, 셀룰로오스는 실리콘 수지의 경화 현상을 방지하며, 벤토나이트 및 카본블랙은 코팅층의 내구성 향상에 따른 크랙 발생을 방지하는 기능을 수행하게 된다.In particular, since the adhesive coating layer 22e is mixed with a thermoplastic acrylic resin, it increases the adhesion of the ball seating portion 22c, cellulose prevents the curing of the silicone resin, and bentonite and carbon black improve the durability of the coating layer. It performs the function of preventing the occurrence of cracks according to the result.

또한, 추가 첨가된 폴리메틸비닐실록산수지는 에폭시 레진의 활성화에 따른 밀착 코팅층(22e)의 탄력성이 개선되고, 지르코늄디옥사이드는 코팅층의 표면 산화 및 변색을 방지하는 이점을 나타낸다.In addition, the additionally added polymethylvinylsiloxane resin improves the elasticity of the adhesion coating layer 22e due to activation of the epoxy resin, and zirconium dioxide exhibits the advantage of preventing surface oxidation and discoloration of the coating layer.

그리고 상기에서 본 발명의 특정한 실시 예가 설명 및 도시되었지만 본 발명의 드레인 노즐 구조가 당업자에 의해 다양하게 변형되어 실시될 수 있음은 자명한 일이다. In addition, although a specific embodiment of the present invention has been described and illustrated above, it is obvious that the drain nozzle structure of the present invention can be variously modified and implemented by those skilled in the art.

예를 들면, 본 발명의 드레인 노즐은 배관라인과 결합하는 방식에 있어서 상기 실시 예에서의 원터치 방식뿐만 아니라 나사결합 방식 등과 같은 다양한 형태 및 방식에 따른 결합이 이루어질 수 있게 된다.For example, in the method of coupling the drain nozzle with the piping line of the present invention, coupling according to various forms and methods such as a screw coupling method as well as the one-touch method in the above embodiment can be achieved.

따라서 이와 같은 변형된 실시 예들은 본 발명의 기술적 사상이나 범위로부터 개별적으로 이해되어져서는 안되며, 이와 같은 변형된 실시 예들은 본 발명의 첨부된 특허청구범위 내에 포함된다 해야 할 것이다.Therefore, such modified embodiments should not be individually understood from the technical spirit or scope of the present invention, and such modified embodiments should be included within the appended claims of the present invention.
