Description

온수관 밀폐장치{Sealed packing apparatus for heating pipe}Sealed packing apparatus for heating pipe

본 발명은 전열선 삽입 온수관에 관한 것으로, 특히 온수관 내부에 삽입시켜 내장하는 전열선의 연결구조와 온수관 내부의 액상으로 된 열매체의 누출을 방지하기 위하여 밀폐수단을 개선하고, 온수관 내부에서 발생되는 압력을 감소시키는 온수관 밀폐장치에 관한 것이다.
The present invention relates to a hot wire insertion hot water pipe, and in particular, to improve the sealing means to prevent the leakage of the heat medium in the liquid phase inside the heating structure and the connection structure of the heating wire inserted into the hot water pipe, and generated inside the hot water pipe It relates to a hot water pipe sealing device for reducing the pressure being.

일반적으로 전기에너지에 의해 실내를 난방하는 전기 가열식 온돌패널 중에는 건식과 습식 타입의 패널이 사용되고 있다.In general, dry and wet panels are used in the electrically heated ondol panels that heat the room by electric energy.

이중 습식타입의 온돌패널에는 일반적으로 난방파이프내부에 전열선을 삽입하는 방식을 많이 사용하게 되는데, 바닥에 매설되어 설치된 난방용 온수관의 내측에 액상의 열매체(물 또는 열전도율이 높은 액체)를 충전한 다음 난방용 온수관의 양측을 밀봉하고, 온수관의 내측으로 전열선을 삽입하게 된다.In general, a double wet type ondol panel uses a heating wire inserted into a heating pipe. The liquid heating medium (water or liquid having high thermal conductivity) is filled inside a heating hot water pipe installed at the bottom. Both sides of the heating hot water pipe are sealed, and a heating wire is inserted into the hot water pipe.

그리하여, 전열선에 전원을 공급하게 되면 발열하여 열매체를 가열하고, 이로 인해 온수관이 가열되어 난방이 행해지게 되는 것이다.Thus, when power is supplied to the heating wire, it generates heat to heat the heating medium, which causes the hot water pipe to be heated to perform heating.

도1은 종래 밀폐장치의 일부를 절결한 분리 사시도이고, 도2는 결합된 단면도로서, 난방용 온수관(1)의 전 길이의 내부에 전열선(2)을 삽입하여 양단부(1a)측으로 관통한 것에 있어서, 온수관(1)의 양 단부(1a)측에 통공(3d)이 형성된 플럭(3)의 관접부(3a)를 끼워 나사결합하고, 플럭(3)의 중앙 요입부(3b)에는 온수관(1)의 전열선(2)이 통공(4h)으로 관통된 탄성질의 실리콘 마개(4)를 끼워 마개(4)의 내단부(4a)가 내턱(3c)에 받치게 하며, 플럭(3)의 외부로 약간 돌출된 마개의 외단부(4b)측에서 크라운 너트(5)의 나사부(5a)를 플럭(3)의 나사부(3e)에 나사결합시키어 마개(4)를 압축밀폐한다.1 is an exploded perspective view of a portion of a conventional sealing device cut away, and FIG. 2 is a cross-sectional view of the combined sealing device, in which a heating wire 2 is inserted into an entire length of a heating hot water pipe 1 and penetrated to both ends 1a. In this case, the tubular portion 3a of the floc 3 having the through hole 3d formed therein is screwed into both ends 1a of the hot water pipe 1, and the hot water in the central recess 3b of the floc 3 is heated. The heating wire 2 of the pipe 1 is fitted with an elastic silicone stopper 4 penetrated by the through hole 4h so that the inner end 4a of the stopper 4 is supported by the inner jaw 3c, and the plug 3 On the outer end portion 4b side of the plug slightly protruding outward, the threaded portion 5a of the crown nut 5 is screwed onto the threaded portion 3e of the floc 3 to seal the stopper 4 by compression.

조립과정은 마개(4)를 플럭(3)의 내부에 밀폐하기 전에 플럭(3)의 통공(3d)을 통하여 온수관(1)에 물을 채우고 전열선(2)을 마개(4)의 통공(4h)으로 관통시킨 다음 실리콘 마개(4)를 플럭(3)의 중앙 요입부(3b)에 끼운 다음 그 외부에 크라운 너트(5)를 체결한다.The assembling process fills the hot water pipe 1 with water through the through hole 3d of the plug 3 and seals the heating wire 2 with the hole of the plug 4 before sealing the stopper 4 to the inside of the plug 3. 4h) and then insert the silicone plug 4 into the center recess 3b of the floc 3 and then fasten the crown nut 5 to the outside thereof.

크라운 너트(5)를 조이면 조일수록 탄성질의 실리콘 마개(4)의 내단부(4a)와 외단부(4b)가 플럭(3)의 내턱(3c)과 크라운 너트(5)의 내면 사이에서 압착으로 수축되어 플럭(3)의 통공(3d)을 밀폐하는 동시에 전열선(2)이 관통된 마개(4)의 통공(4h)도 압축되어 전열선(2)이 압착 고정된다.As the crown nut 5 is tightened, the inner end portion 4a and the outer end portion 4b of the elastic silicone stopper 4 are pressed together between the inner jaw 3c of the floc 3 and the inner surface of the crown nut 5. The through hole 4h of the stopper 4 through which the heating wire 2 penetrates is also compressed by being contracted to seal the through hole 3d of the floc 3, and the heating wire 2 is compressed and fixed.

그런데, 이러한 마개(4)의 통공(4h)에 전열선(2)을 수작업으로 삽입한 다음 기밀을 위하여 크라운 너트(5)를 플력(3)에 체결하게 되지만, 온수관(1)이 가열되면서 물이 데워져 수증기가 발생하고, 이로인해 내부 압력이 증가하게 되면 통공(4h)과 전열선(2) 사이의 공간을 통해 수증기가 배출됨으로써 온수관(1) 내부의 물이 줄어들게 된다.By the way, the heating wire (2) is manually inserted into the through hole (4h) of the stopper (4) and then the crown nut (5) is fastened to the force (3) for airtight, but the water pipe (1) is heated The warmed water vapor is generated, and when the internal pressure increases, water vapor is discharged through the space between the through hole 4h and the heating wire 2 to reduce the water in the hot water pipe 1.

즉, 실리콘으로 된 마개(4)와 테프론 재질로 전열선(2)의 피복이 서로 이질적이므로 접합성이 결여되어 상호간 기밀이 쉽지 않아 간격이 발생하고, 온도 상승시 그 간격을 통해 수증기가 배출되는 누수가 발생됨으로써 온수관(1)내에서 전열선(2)이 수면위로 노출되어 과도한 열이 발생하게 되며, 이로인해 전열선(2)의 단선이 발생하는 문제점이 있다.That is, because the cover of the plug 4 and the Teflon made of silicon is heterogeneous, the gap between the two is not easy because of the lack of bonding and the airtightness is not easy to leak. As a result, the heating wire 2 is exposed on the water surface in the hot water pipe 1 to generate excessive heat, thereby causing a problem in that the heating wire 2 is disconnected.

또한, 전열선(2)이 마개(4)에 끼워진 상태이므로 수작업으로 인한 전열선(2)을 잡아당기게 되면 쉽게 온수관(1)으로 빠져나오게 되어 불량률이 매우 높아지는 문제점이 있다.In addition, since the heating wire 2 is inserted into the stopper 4, when the heating wire 2 is pulled out by hand, the heating wire 2 is easily pulled out to the hot water pipe 1, so that the defective rate is very high.

즉 밀폐수단인 실리콘으로 된 마개(4)가 중앙에 전열선(2)이 관통하도록 통공(4h)이 있게 만들어졌기 때문에 온도가 상승시 내부에서 발생하는 압력에 취약해 누수나 변형을 가져오게 되고, 미세한 통공(4h)으로 전열선(2)을 관통시키는 작업이 매우 정교함을 요하기 때문에 제품의 불량률을 증가시키고, 또한 생산시간이 증가되어 제조비용이 늘어나는 문제점이 있다.That is, because the stopper (4) made of silicon as a sealing means has a through hole (4h) so that the heating wire (2) penetrates in the center, it is vulnerable to pressure generated inside when the temperature rises, resulting in leakage or deformation. Since the work of penetrating the heating wire 2 to the fine through hole (4h) is very sophisticated, there is a problem that increases the defective rate of the product, and also increases the production time to increase the manufacturing cost.

특히 온수관(1) 내부에 삽입된 전열선(2)에 의해 발생할수 있는 전기적 합선 으로 인하여 화재 등 여러가지 여러 가지 결함이 지적되어오고 있다.In particular, various shortcomings, such as fire, have been pointed out due to electrical short-circuits that may be caused by heating wires 2 inserted into the hot water pipes 1.

다시말하면 액상의 열매체가 충전되어있는 온수관(1) 내부의 전열선(2)이 전원장치로부터 전기를 공급받아 열을 발생하는 과정에서 온수관(1) 내부의 액상 열매체가 소진되므로 전열선(2)이 액상 밖으로 노출하게 되고, 이로인한 과부하로 전열선(2)이 단선되거나 과열로 인해 온수관(1)이 녹아내리는 현상이 발생하는 문제점이 종종 발생하게 되는 것이다.
In other words, the heat transfer wire (2) inside the hot water pipe (1) filled with the liquid heat medium is exhausted because the liquid heat medium inside the hot water pipe (1) is exhausted in the process of generating heat by receiving electricity from the power supply device. Exposed to the liquid phase, due to the overload caused by the heating wire (2) is disconnected or the problem that the phenomenon that the hot water pipe 1 is melted due to overheating often occurs.

본 발명은 이러한 종래의 문제점을 해결하기 위하여, 전열선의 외측을 실리콘으로 피복하고, 실리콘으로 형성된 마개를 통공이 없이 관통하도록 일체형으로 몰딩함으로써 그 밀폐구조를 단순화하고, 셍산시간 단축과 제조비용을 절감하도록 하며, 기밀성을 증가시켜 온수관 내부의 누수를 방지하도록 한 온수관 밀폐장치를 제공하는데 그 목적이 있다.In order to solve the conventional problems, the present invention coats the outside of the heating wire with silicon, and integrally molds the plug formed of silicon to penetrate through the hole without simplification, thereby simplifying the sealing structure, reducing the acid production time and reducing the manufacturing cost. The purpose of the present invention is to provide a hot water pipe sealing device to prevent leakage of water inside the hot water pipe by increasing airtightness.

또한, 복원력이 우수한 실리콘 스폰지를 온수관 내부에 삽입함으로써 온도 상승시 온수관 내부에서 발생할수 있는 내부압력을 감소시켜 온수관의 파손을 방지하는데 또 따른 목적이 있다.
In addition, by inserting a silicone sponge having excellent restoring force into the hot water pipe, there is another object to prevent the breakage of the hot water pipe by reducing the internal pressure that may occur inside the hot water pipe when the temperature rises.

상기의 목적을 달성하기 위한 본 발명의 온수관 밀폐장치는, 난방용 온수관의 내부에 전열선이 삽입되고, 온수관의 양 끝단이 마개에 의해 밀폐된 온수관에 있어서,In the hot water pipe sealing device of the present invention for achieving the above object, in the hot water pipe is inserted into the heating water pipe for heating, both ends of the hot water pipe is sealed by a stopper,

상기 전열선은 그 외측이 실리콘으로 피복되어 전원선과 연결체에 의해 가압되어 연결되고, 실리콘 재질로 된 마개의 몰딩시에 상기 연결체에 의해 체결된 부위가 마개의 내측으로 삽입되어 전열선과 전원선이 마개를 관통하도록 일체로 압축사출에 의해 몰딩되며, 상기 마개의 일부측은 온수관의 내측으로 삽입됨과 아울러 타측은 플럭의 내측으로 삽입되어 마개를 수용한 플럭이 온수관의 외측에 체결된 크라운 너트와 체결되도록 구성된다.The heating wire is coated with silicon on the outside of the heating wire and is pressed by the power supply line and the connecting body. When molding the plug of the silicon material, the portion fastened by the connecting member is inserted into the inside of the plug so that the heating wire and the power wire are Molded by compression injection integrally to penetrate the stopper, a portion of the stopper is inserted into the inner side of the hot water pipe and the other side is inserted into the inside of the floc and the crown containing the plug is fastened to the outside of the hot water pipe and the crown nut It is configured to be fastened.

또한 상기 온수관의 끝단 내측에는 실리콘 스폰지가 삽입된다.
In addition, a silicone sponge is inserted inside the end of the hot water pipe.

이러한 본 발명은 전열선의 피복과 마개가 동일한 재질의 실리콘으로 형성되어 일체로 압축사출에 의해 몰딩됨으로써 그 구조가 매우 단순화되고, 생산시간의 단축과 이에 따른 제조비용을 절감할 수 있다.In the present invention, the coating and the stopper of the heating wire are formed of silicon of the same material and are integrally molded by compression injection, thereby greatly simplifying the structure, shortening the production time and thus reducing manufacturing cost.

또한, 기밀성이 매우 높아 온수관으로부터의 누수가 발생하지 않게 되고, 이로인해 전열선이 온수관 내부에서 수면위로 노출되지 않아 단선이 발생하지 않게 되어 제품의 신뢰성을 향상시키고, 내구성이 뛰어난 장점이 있다.In addition, since the airtightness is very high, no water leakage from the hot water pipe is generated, and thus, the heating wire is not exposed to the water level inside the hot water pipe so that disconnection does not occur, thereby improving the reliability of the product and having excellent durability.

또한 온수관의 내측에 다공성의 실리콘인 스폰지 실리콘이 삽입됨으로써 온수관 내부의 물이 가열되어 압력이 증가하면 그 압력에 의해 수축하고, 압력이 낮아지면 다시 팽창함으로써 압력조절이 가능하게 되며, 이로인해 온수관의 손상도 방지하는 장점을 갖는다.
In addition, by inserting sponge silicon, which is porous silicone, inside the hot water pipe, the water inside the hot water pipe is heated and contracted by the pressure when the pressure increases, and when the pressure decreases, the pressure can be controlled by expanding again. It also has the advantage of preventing damage to the hot water pipe.

본 발명을 첨부한 도면 3 내지 5까지를 참조하여 상세히 설명한다.With reference to the accompanying drawings, the present invention will be described in detail.

도3은 본 발명의 결합 단면 구조를 보인 도이고, 도4는 분해 사시도를 보인 도로서, 물이 충전된 온수관(100)의 내부에 전열선(120)이 삽입되고, 온수관(100)의 단부 외측에는 크라운 너트(150)가 위치하며, 상기 크라운 너트(150)에는 마개(110)를 수용한 플럭(170)이 체결되어 기밀을 유지하게 된다.Figure 3 is a view showing a coupling cross-sectional structure of the present invention, Figure 4 is an exploded perspective view, the heating wire 120 is inserted into the inside of the hot water pipe 100 is filled with water, the hot water pipe 100 The crown nut 150 is located outside the end, and the crown nut 150 is fastened to the plug 170 accommodating the stopper 110 to maintain airtightness.

상기 플럭(170)의 내측에 수용된 마개(110)는 전열선(120)과 전원선(130)이 연결체(140)에 의해 연결된 상태에서 압축사출에 의해 일체화 되는데, 상기 전열선(120)은 도5에 도시한 바와같이 발열선(121)의 외측에 절연을 위한 테프론층(122)이 피복되며, 테프론층(122)의 외측에도 절연을 위한 실리콘층(123)이 피복되어 있다.The stopper 110 accommodated inside the plug 170 is integrated by compression injection in the state in which the heating wire 120 and the power supply line 130 are connected by the connector 140. The heating wire 120 is illustrated in FIG. 5. As shown in FIG. 2, the Teflon layer 122 for insulation is coated on the outer side of the heating line 121, and the silicon layer 123 for insulation is coated on the outer side of the Teflon layer 122.

그리고 전열선(120)의 끝단은 전원선(130)과 연결되는데, 그 연결부위에 금속재 링 형태의 연결체(140)가 씌워지고, 연결체(140)를 가압함으로써 전열선(120)과 전원선(130)이 상호간 고정되면서 전기적으로 연결된다. And the end of the heating wire 120 is connected to the power line 130, the connection portion 140 of the metal ring-shaped is covered on the connection portion, by heating the heating wire 120 and the power line ( 130 are fixed to each other and electrically connected.

상기 마개(110)는 실리콘 재질로 되어 있으며, 몰딩성형시에 상기 전열선(120)과 전원선(130)의 연결부위를 내측에 수용하면서 일체로 압축사출되어 형성된다.The stopper 110 is made of a silicon material, and is integrally compressed and ejected while receiving a connection portion between the heating wire 120 and the power supply line 130 during molding.

전열선(120)의 외측은 실리콘층(123)으로 피복되어 있으므로, 또한 동일한 실리콘 재질로 형성된 마개(110)와 접합성이 매우 뛰어나서 이탈이 발생하지 않고 기밀성이 매우 증가된다.Since the outer side of the heating wire 120 is covered with the silicon layer 123, it is also very excellent bondability with the stopper 110 formed of the same silicon material, so that the separation does not occur and the airtightness is greatly increased.

또한, 금속재의 연결체(140)가 장착된 연결부위는 외측으로 튀어나온 돌기형태를 가짐으로써 이 또한 전열선(120)과 전원선(130)이 마개(110)로부터 이탈되는 것을 방지하게 된다.In addition, the connection portion on which the metal connecting member 140 is mounted has a protrusion protruding outward, thereby preventing the heating wire 120 and the power supply line 130 from being separated from the plug 110.

즉, 마개(110)를 파손하지 않는 한 전열선(120)과 전원선(130)은 마개(110)로부터 이탈되지 않고 고정된다.
That is, as long as the stopper 110 is not damaged, the heating wire 120 and the power supply line 130 are fixed without being separated from the stopper 110.

이러한 본 발명의 결합과정을 설명하면, 먼저 크라운 너트(150)를 온수관(100)의 외측으로 끼운 다음, 내측에 나사부(161)를 갖는 링 형태의 걸림부(160)를 온수관(100)의 단부 외측에 체결하여 크라운 너트(150)가 온수관(100)으로부터 이탈되는 것을 방지한다.Referring to the coupling process of the present invention, first the crown nut 150 is inserted into the outside of the hot water pipe 100, and then the ring-shaped locking portion 160 having a screw portion 161 on the inside of the hot water pipe 100 It is fastened to the outside of the end portion of the crown nut 150 is prevented from being separated from the hot water pipe (100).

이후 전열선(120)과 전원선(130)이 내장되어 압축사출된 마개(110)를 플럭(170)의 내측으로 삽입시켜 전원선(130)이 요입부(172)를 통해 외측으로 노출되도록 하고, 전열선(120)을 온수관(100)의 내측으로 삽입시킨 다음 크라운 너트(150)의 나사부(151)와 플럭(170)의 나사부(171)를 상호 체결하여 고정시키게 된다.Then, the heating wire 120 and the power supply line 130 are embedded to insert the compression injection plug 110 into the inside of the flocks 170 so that the power supply line 130 is exposed to the outside through the concave portion 172, The heating wire 120 is inserted into the hot water pipe 100, and then the screw 151 of the crown nut 150 and the screw 171 of the flocks 170 are fastened to each other to be fixed.

이때, 플럭(170)의 단부에 형성된 관접부(175)는 온수관(100)과 마개(110) 사이에 끼워져 마개(110)를 안정적으로 고정시키게 되며, 마개(100)의 외측에는 다단의 단턱(111,112)이 형성되어 플럭(170) 내부의 턱부(173,174)에 걸림으로써 이탈이 방지된다.At this time, the pipe 175 formed at the end of the plug 170 is inserted between the hot water pipe 100 and the stopper 110 to stably fix the stopper 110, the stepped end of the multi-step on the outside of the stopper 100 (111, 112) is formed to be caught by the jaws (173, 174) inside the floc 170 to prevent the departure.

결국 마개(110)와 전열선(120), 그리고 전원선(130)을 일체로 압축사출함으로써 기밀성을 증가시켜 온수관(100) 내부의 물이 누수에 의해 손실되는 것을 방지하고, 전열선(120)이 수면위로 노출되는 것이 방지되어 과열방지에 따른 전열선(120)과 온수관(100)의 손상을 방지하는 것이다.Eventually, the plug 110, the heating wire 120, and the power supply line 130 by compression injection integrally increases the airtightness to prevent the water inside the hot water pipe 100 is lost by leakage, the heating wire 120 is Exposure to the water surface is prevented to prevent damage to the heating wire 120 and the hot water pipe 100 according to the overheating prevention.

한편, 보통 온수관내에서 전열선의 엉킴이나 꼬임이 발생하게 되면 전원인가시 엉키거나 꼬인 부분에서 국부과열로 인해 전열선의 소손이 발생하게 된다.On the other hand, when the heating wire is tangled or twisted in the hot water pipes, the heating wire burns out due to local overheating at the tangled or twisted portion when the power is applied.

따라서, 전열선(120)이 온수관(100) 내에서 가급적 팽팽한 상태를 유지하는 것이 바람직한데, 종래에는 팽팽한 상태를 유지하기 위하여 전열선을 잡아당기게 되면 마개로부터 이탈하게 됨으로써 설치불량이 많이 발생하게 되지만, 본 발명을 이용하는 경우에는 온수관(100)의 반대쪽에서 전열선(120)을 팽팽하게 잡아당겨도 마개(110)로부터 전열선(120)이 이탈하지 않으므로 온수관(100) 내에서의 올바른 전열선(120)의 설치가 가능하게 된다.
Therefore, it is preferable that the heating wire 120 is maintained in the hot state as much as possible in the hot water pipe 100. In the related art, when the heating wire is pulled in order to maintain the tight state, the heating wire 120 is detached from the plug, thereby causing a lot of installation defects. In the case of using the present invention, even if the heating wire 120 is pulled tightly from the opposite side of the hot water pipe 100, the heating wire 120 does not escape from the stopper 110, so that the correct heating wire 120 in the hot water pipe 100 is provided. Installation is possible.

도6은 온수관(100) 내부 끝단에 실리콘 스폰지(180)를 삽입하여 온수관(100) 내부에서 발생하는 압력을 흡수하게 되는데, 이러한 실리콘 스폰지(180)는 부드럽고 탄성이 풍부하여 움직임을 쉽게 흡수하고 밀폐성이 뛰어나며, 복원력이 뛰어나고 탄성이 좋은 것이 특징이다.Figure 6 is inserted into the silicone sponge 180 at the inner end of the hot water pipe 100 to absorb the pressure generated inside the hot water pipe 100, this silicone sponge 180 is soft and rich in elasticity to easily absorb the movement It has excellent sealing property, excellent resilience and good elasticity.

따라서, 전열선(120)에 의한 물의 가열에 의해 온수관(100) 내부의 압력이 증가하면, 실리콘 스폰지(180)가 그 압력에 의해 수축하여 압력을 흡수하고, 다시 압력이 낮아지면 팽창함으로써 온수관(100)이 압력에 의해 부풀어 파손되는 것을 방지하게 된다.Therefore, when the pressure inside the hot water pipe 100 increases by heating the water by the heating wire 120, the silicone sponge 180 contracts by the pressure to absorb the pressure, and when the pressure decreases again, the hot water pipe expands. It is possible to prevent the 100 from being swollen and broken by the pressure.

그리고, 온수관(100)의 타측 단부에는 크라운 너트(150)와 밀폐된 플럭(170)에 의해 마감됨으로써 기밀이 유지된다.
And, the other end of the hot water pipe 100 is closed by the crown nut 150 and the sealed flocks 170 is maintained airtight.
