보일러 분배기용 관이음{PIPE JOINT FOR BOILER DISTRIBUTOR}Pipe joint for boiler distributor{PIPE JOINT FOR BOILER DISTRIBUTOR}

본 고안은 보일러 분배기용 관이음에 관한 것으로, 더욱 상세하게는 분배기의 몸체에 융착되는 관이음을 인서트 사출 작업을 배제하고 한 번의 사출 성형으로 제조함으로써, 제조공정을 단축시켜 생산성은 높이고 제조비용은 절감할 수 있는 보일러 분배기용 관이음에 관한 것이다.The present invention relates to a pipe joint for a boiler distributor, more specifically, by excluding a pipe joint fused to the body of the distributor by one injection molding, excluding the insert injection operation, shortening the manufacturing process, increasing productivity and manufacturing cost It relates to a pipe joint for a boiler distributor that can save.

일반적으로 단독주택, 아파트, 다세대주택 및 빌딩 등의 건물은, 각 건물 내의 여러 장소로 냉수와 온수를 공급할 수 있도록 보일러용 분배기 조립체가 설치된다. 발명의 명칭이 '분배기용 관이음 및 그 제조방법'인 대한민국 특허 제10-0952354호는 본 고안의 고안자가 발명한 것이다. 도 4를 참조하면, 종래 보일러용 분배기는 합성수지로 제조된 분배기의 몸체(110)에 관이음(140)이 열융착으로 고정된다. 관이음(140)은 중공형상이고 일단의 외주면에 나사산(141)이 형성된 합성수지로 제조된 나사 연결부(140a)를 사출 성형한다. 그리고, 나사 연결부(140a)의 타단에 몸체(110)의 단부(112)와 융착되는 부분(142)을 구비하도록 합성수지로 사출 성형된 융착 연결부(140b)를 포함하는 기술적 구성이 개시되어 있다.In general, in buildings such as single-family houses, apartments, multi-family houses, and buildings, a distributor assembly for a boiler is installed to supply cold water and hot water to various places in each building. The Republic of Korea Patent No. 10-0952354, entitled'The pipe joint for the distributor and its manufacturing method', was invented by the inventor of the present invention. Referring to Figure 4, the conventional boiler distributor is a pipe joint 140 is fixed to the body 110 of the distributor made of synthetic resin by heat fusion. The pipe joint 140 is hollow and injection-molded a screw connection portion 140a made of synthetic resin having a thread 141 formed on one outer peripheral surface. And, the other end of the screw connection portion (140a) has a technical configuration including a fused connection portion (140b) injection-molded with synthetic resin to have a portion 142 to be fused with the end 112 of the body (110).

그러나 종래 분배기의 몸체에 열융착되는 관이음은 맨 처음 사출 성형에 의해 나사 연결부를 제조하고, 다음으로 나사 연결부의 타단에 인서트 사출에 의해 융착 연결부를 성형한다. 따라서, 관이음을 제조하기 위해 반드시 사출 성형과 인서트 작업이 순차적으로 진행되어야 하기 때문에 작업 시간이 많이 소요되고 생산성이 떨어지는 문제점이 있다. 사출 성형된 나사 연결부의 타단에 융착 연결부를 인서트 사출 성형할 때 작업자의 실수나 사출시 주입 부족으로 인해 불량률이 발생하는 문제점이 있다. However, the pipe joint which is heat-sealed to the body of the conventional distributor is firstly manufactured by screwing the screw connection part by injection molding, and then molded by the injection molding of the other end of the screw connection part. Therefore, since injection molding and insert operations must be sequentially performed in order to manufacture pipe joints, there is a problem in that it takes a lot of work time and decreases productivity. When insert-molding the fusion spliced part to the other end of the injection-molded screw connection part, there is a problem in that a defect rate occurs due to an operator's mistake or insufficient injection during injection.

또한, 보일러용 분배기를 제조하기 위해 분배기의 몸체 및 나사 연결부를 제조하는 사출 성형장비와 나사 연결부에 융착 연결부를 인서트 사출하는 인서트 사출 성형장비가 필요하다. 따라서, 초기 투자 비용이 많이 소요될 뿐만 아니라 각각의 장비를 유지하고 관리하는 비용이 점증적으로 증가되는 문제점이 있다.In addition, in order to manufacture a distributor for a boiler, there is a need for an injection molding equipment for manufacturing a body and a screw connection of a distributor and an insert injection molding equipment for insert injection of a fusion connection to a screw connection. Therefore, there is a problem in that not only is the initial investment cost high, but the cost of maintaining and managing each equipment is gradually increased.

본 고안은 상기와 같은 종래의 문제점을 해결하기 위한 것으로, 관이음 제조시 인서트 사출작업을 배제하고 높은 강도의 유리섬유강화 폴리프로필렌 합성수지를 한 번에 사출 성형하여 제조한다. 따라서 보일러용 분배기의 제조공정을 단축시켜 생산성을 높이고, 다른 부품과의 체결이 용이하고 열융착 부분이 뛰어난 기밀성을 유지할 수 있는 보일러 분배기용 관이음을 제공하는 것을 목적으로 한다.The present invention is to solve the conventional problems as described above, it is manufactured by injection molding at a time, excluding the insert injection operation during the manufacture of pipe joints and glass fiber-reinforced polypropylene synthetic resin of high strength. Accordingly, an object of the present invention is to provide a pipe joint for a boiler distributor that shortens the manufacturing process of the boiler distributor to increase productivity, to facilitate fastening with other parts, and to maintain excellent airtightness of the heat-sealed portion.

이와 같은 목적들을 달성하기 위한 본 고안의 특징은, 중공형상이고 외주면에 중공의 내부와 연통되도록 복수의 연결구를 구비한 몸체와, 복수의 연결구에 각각 설치된 밸브들과, 몸체의 양단부에 열융착된 관이음(140)을 포함하는 보일러용 분배기에 있어서, 몸체는 폴리프로필렌랜덤(PPR : Poly Propylene Random Copolymer)으로 제조되고, 관이음은 중공형상이고 일단의 외주면에 수나사(141)가 형성되며, 유리섬유강화 폴리프로필렌(FR-PP : Glass Fiber Reinforced Poly Propylene)과 폴리프로필렌랜덤(PPR : Poly Propylene Random Copolymer)을 혼합하여 사출 성형하는 것을 특징으로 하는 보일러 분배기용 관이음을 개시한다.A feature of the present invention for achieving these objects is a hollow shape and a body having a plurality of connectors so as to communicate with the inside of the hollow on the outer circumferential surface, valves respectively installed in the plurality of connectors, and heat-sealed to both ends of the body In the distributor for a boiler comprising a pipe joint 140, the body is made of polypropylene random copolymer (PPR), the pipe joint is hollow and a male screw 141 is formed on one outer circumferential surface, glass Disclosed is a pipe joint for a boiler distributor, characterized by injection molding by mixing fiber-reinforced polypropylene (FR-PP: Glass Fiber Reinforced Poly Propylene) and polypropylene random copolymer (PPR).

본 고안에 의하면, 분배기의 몸체에 한 번의 사출 성형작업에 의해 제조된 관이음을 열융착으로 고정한다. 따라서 제조공정을 단축시킨 관이음을 분배기의 몸체에 설치함으로써 보일러용 분배기의 생산성이 향상되는 효과가 있다. 또한, 관이음을 제조할 때 인서트 사출장비가 필요하지 않으므로 초기 투자 비용을 절감할 수 있다.According to the present invention, the pipe joint manufactured by one injection molding operation is fixed to the body of the distributor by heat fusion. Therefore, there is an effect of improving the productivity of the distributor for the boiler by installing the pipe joint to shorten the manufacturing process in the body of the distributor. In addition, since the insert injection equipment is not required when manufacturing the pipe joint, the initial investment cost can be reduced.

본 고안의 관이음은 높은 강도의 유리섬유강화 폴리프로필렌 합성수지로 제조되기 때문에 분배기의 몸체나 다른 부품과의 결합이 용이하다. 또한, 결합된 상태에서 5°내지 95°범위의 저온과 고온의 온도차가 급격하게 변하는 관수가 흐르더라고 열융착 부분이나 결합 부분에서 누수현상이 발생하지 않아 뛰어난 기밀성을 지속적으로 유지할 수 있는 효과가 있다.Since the pipe joint of the present invention is made of high-strength glass fiber-reinforced polypropylene synthetic resin, it is easy to combine with the distributor body or other parts. In addition, there is an effect of continuously maintaining excellent airtightness because water leakage does not occur in the heat-sealed part or the coupled part, even when the water temperature rapidly changes between the low and high temperature ranges of 5° to 95° in the combined state. .

먼저, 도 1 및 도 3을 참조하면 본 고안의 보일러용 분배기(100)는 몸체(110)를 구비한다. 도 1에 도시된 것과 같이 몸체(110)는 양단부(112)가 개방된 중공형상이고, 외주면 하부에 간격을 두고 복수의 연결구(미도시 됨)가 형성된다. 연결구들은 외부로부터 유입되는 유체가 흐르도록 몸체(110)의 내부와 연통되어 있다. 본 고안의 연결구는 몸체(110)의 상부에 하나 하부에 3개 형성되어 있으나 이에 한정하는 것은 아니고, 상부가 없고 하부에 3개 이상이거나 상부가 있고 하부가 3개 이상 등 다양한 형태로 제조할 수 있음은 물론이다. 밸브(120)는 몸체(110)의 하부에 형성된 복수의 연결구에 열융착으로 고정된다. 밸브(120)는 분배기의 몸체(110)에 유입된 냉수 또는 온수를 밸브(120)의 개폐 작동에 따라 건물 내의 여러 장소로 공급하거나 차단하는 역할을 한다.First, referring to FIGS. 1 and 3, the distributor 100 for a boiler of the present invention includes a body 110. As shown in Figure 1, the body 110 has a hollow shape with both ends 112 open, and a plurality of connectors (not shown) are formed at intervals on the outer circumferential surface. The connectors are in communication with the inside of the body 110 so that the fluid flowing from the outside flows. The connector of the present invention is formed on the upper part of the body 110, but three are formed on the lower part, but the present invention is not limited thereto. Yes, of course. The valve 120 is fixed by heat fusion to a plurality of connectors formed at the bottom of the body 110. The valve 120 serves to supply or block cold water or hot water flowing into the body 110 of the distributor to various places in the building according to the opening and closing operation of the valve 120.

보조밸브(130)는 몸체(110)의 상부에 형성된 연결구에 설치되고, 분배기의 몸체(110) 내부에 생성된 공기를 배출할 때 사용한다. 보조밸브(130)는 예열기를 이용하여 연결구(미도시 됨)의 외주면과 보조밸브(미도시 됨)의 내주면을 각각 예열한 후 융착한다.The auxiliary valve 130 is installed in the connector formed on the upper portion of the body 110, and is used to discharge the air generated inside the body 110 of the distributor.

본 고안은 분배기의 몸체(110)와 밸브(120) 및 보조밸브(130)는 비용이 저렴하고 제조가 용이한 폴리프로필렌랜덤(PPR : Poly Propylene Random Copolymer)으로 제조한다. 이와 같이 동일한 재질로 제조함으로써 분배기의 몸체(110)에 밸브(120)와 보조밸브(130)의 열융착이 용이하고, 장시간 사용하여도 뛰어나 기밀성을 유지할 수 있다.In the present invention, the body 110 of the distributor, the valve 120 and the auxiliary valve 130 are made of polypropylene random copolymer (PPR), which is inexpensive and easy to manufacture. By manufacturing the same material as described above, it is easy to heat-seal the valve 120 and the auxiliary valve 130 to the body 110 of the distributor, and can maintain excellent airtightness even when used for a long time.

도 3을 참조하면, 관이음(140)은 중공형상이고 일단은 외주면에 수나사(141)를 구비하고, 타단은 몸체(110)의 양단부(112)에 각각 융착되는 관이음 융착부(142)가 형성된다. 종래 관이음은 수나사 부분과 융착 부분을 각각 다른 재질로 제조하였으나, 본 고안은 합성수지로 일체로 사출 성형하여 제조한다. 따라서, 작업공정이 줄어들어 생산성이 향상되고 제조 비용을 절감하는 효과가 있다.Referring to FIG. 3, the pipe joint 140 has a hollow shape, and one end is provided with a male screw 141 on its outer circumferential surface, and the other end has a pipe joint fusion section 142 fused to both ends 112 of the body 110, respectively. Is formed. Conventional pipe joints are made of different materials for the male thread portion and the fused portion, but the present invention is manufactured by injection molding integrally with synthetic resin. Therefore, the work process is reduced, thereby improving productivity and reducing manufacturing costs.

한 번의 사출 성형으로 제조된 관이음(140)은 수나사(141)를 구비하기 위해 합성수지 중 강도가 높은 유리섬유강화 폴리프로필렌(FR-PP : Glass Fiber Reinforced Poly Propylene, 일명 'PP롱글라스'라 한다)으로 제조한다. 유리섬유강화 폴리프로필렌은 탄성률, 열변형온도, 피로특성 등이 뛰어나고 특히 고온에서 그 특성이 우수하다. 또한, 관이음(140)은 70~85%의 유리섬유강화 폴리프로필렌(FR-PP : Glass Fiber Reinforced Poly Propylene)와 15~30%의 폴리프로필렌랜덤(PPR : Poly Propylene Random Copolymer)을 혼합하여 제조할 수도 있다.The pipe joint 140 manufactured by one injection molding is high-strength glass fiber reinforced polypropylene (FR-PP: Glass Fiber Reinforced Poly Propylene), so-called'PP Long Glass' in order to have a male screw 141. ). Glass fiber-reinforced polypropylene has excellent elastic modulus, heat deflection temperature, and fatigue properties, and is particularly excellent at high temperatures. In addition, the pipe joint 140 is produced by mixing 70 to 85% of glass fiber reinforced polypropylene (FR-PP: Glass Fiber Reinforced Poly Propylene) and 15 to 30% of polypropylene random copolymer (PPR). You may.

상기에서와 같이 관이음(140)은, 폴리프로필렌(PP)이 혼합되어 있기 때문에 폴리프로필렌랜덤(PPR)으로 제조된 몸체(110)와 동일한 내마모성, 내열성, 고온 내압성, 열팽창계수 등의 특성이 있다. 즉, 몸체(110)와 관이음(140)의 열융착된 부분은 고온의 관수가 통과하게 되면 동시에 팽창하게 되고, 저온의 관수가 통과하게 되면 동시에 수축한다. 이와 같이 동시에 동일 방향으로 팽창과 수축되기 때문에 장시간 사용하여도 열융착된 부분이 벌어져 틈이 발생하지 않아 누수현상이 발생하지 않는다.As in the above, the pipe joint 140 has the same abrasion resistance, heat resistance, high temperature pressure resistance, and thermal expansion coefficient as the body 110 made of polypropylene random (PPR) because polypropylene (PP) is mixed. . That is, the heat-sealed portion of the body 110 and the pipe joint 140 expands at the same time when the hot water passes, and contracts at the same time when the cold water passes. In this way, since it expands and contracts in the same direction at the same time, even if it is used for a long time, the heat-sealed part does not open, so there is no gap, so no leakage occurs.

본 고안에서와 같이 관이음(140)의 관이음 융착부(142)를 몸체(110)의 단부(112)에 열융착이 가능한 이유는 합성수지의 재질, 강도 및 두께에 따라 예열시간과 예열온도를 각각 조정할 수 있는 예열장치를 사용하기 때문이다.As in the present invention, the reason why heat fusion of the pipe joint fusion part 142 of the pipe joint 140 to the end 112 of the body 110 is possible is to determine the preheating time and the preheating temperature according to the material, strength and thickness of the synthetic resin. This is because a preheating device that can be adjusted individually is used.

캡(150)은 몸체(110) 왼쪽에 융착된 관이음(140)의 개방된 일단을 밀폐하기 위해 관이음(140)의 수나사(141)와 나사결합되도록 대응되는 내주면에 암나사(151)가 형성되어 있다. 캡(150)은 분배기의 몸체(110)와 동일한 재질인 폴리프로필렌랜덤(PPR : Poly Propylene Random Copolymer)으로 제조되나 이에 한정하는 것은 아니고 다양한 재질로 제조될 수 있음은 물론이다. The cap 150 is formed with a female screw 151 on a corresponding inner circumferential surface to be screwed with a male screw 141 of the pipe joint 140 to seal the open end of the pipe joint 140 fused to the left side of the body 110 It is. The cap 150 is made of polypropylene random copolymer (PPR), which is the same material as the body 110 of the distributor, but is not limited thereto, and can be made of various materials.

연결관(160)은 몸체(110)의 오른쪽에 융착된 관이음(140)의 수나사(141)와 나사결합되도록 대응되는 내주면에 암나사(미도시 됨)이 형성되어 있다. 연결관(160)은 분배기의 몸체(110)로 유체를 공급하거나 배출하기 위해 다른 부품과 연결하기 위해 설치된다. 연결관(160)과 캡(150)은 몸체(110)의 반대 위치에 나사결합될 수도 있다.The connecting pipe 160 is formed with a female screw (not shown) on a corresponding inner circumferential surface to be screwed with the male screw 141 of the pipe joint 140 fused to the right side of the body 110. The connecting pipe 160 is installed to connect with other parts to supply or discharge fluid to the body 110 of the distributor. The connecting pipe 160 and the cap 150 may be screwed to opposite positions of the body 110.

본 고안에 따른 보일러 분배기용 관이음은, 암나사가 쉽게 변형되는 것을 방지하고 분배기의 몸체와 열융착이 가능하도록 강도가 높은 유리섬유강화 폴리프로필렌으로 한 번의 사출공정에 의해 제조한다. 이와 같이 제조된 관이음은 저렴한 비용으로 대량 생산이 가능하여 보일러용 분배기의 제조비용을 혁신적으로 절감할 수 있다. 또한, 몸체에 열융착된 관이음은 동일한 특성을 갖는 재질로 제조되기 때문에 5°내지 95°범위의 온도차가 급격하게 변하는 관수가 흐르더라고 열융착 부분이나 결합 부분에서 누수현상이 발생하지 않아 기밀성이 매우 우수하다.The pipe joint for the boiler distributor according to the present invention is manufactured by a single injection process with a high-strength glass fiber-reinforced polypropylene to prevent female threads from easily deforming and to be heat-sealed with the body of the distributor. The pipe joints manufactured in this way can be mass-produced at a low cost, thereby reducing the manufacturing cost of the boiler distributor. In addition, since the pipe joint heat-sealed to the body is made of a material having the same characteristics, there is no leakage from the heat-sealed portion or the coupling portion because water flows rapidly changing the temperature difference in the range of 5° to 95°. It is very good.
