주택(APT, 연립주택)의 세대 내에서 수도꼭지를 사용하면서 수도꼭지의 밸브를 열고 닫는 과정에서 흐르는 물이 밸브에 의해 갑자기 차단되면 충격압력파가 발생하여 주위의 관 또는 관부속에 전달하여 소음이나 떨림 현상을 발생시키는데, 이것을 워터해머라고 한다.If the flowing water is suddenly cut off by the valve while opening and closing the valve of the faucet while using the faucet within the household (APT, townhouse), a shock pressure wave is generated and transmitted to the surrounding pipe or pipe part, causing noise or vibration. This is called a water hammer.

상기한 문제점을 줄이거나 방지하려고 개스가 밀폐된 챔버를 설치하거나, 밀폐된 공간부를 가진 챔버에 공기 또는 스프링을 장치한 충격흡수장치를 배관중에 설치하고 있는데, 이는 공기, 개스의 압축성, 스프링의 탄발계수를 이용, 압력파인 비압축성인 물을 접수하여 압력파를 감쇄하도록 한 것이다.In order to reduce or prevent the above problems, a gas-tight chamber is installed, or an air or spring-absorbing device is installed in a pipe having an airtight space, such as air, gas compressibility, and spring spring. The coefficients are used to receive incompressible water, which is a pressure wave, to attenuate the pressure wave.

하지만 상기의 장치들을 배관에 설치하려면 별도의 이음관에 의해 관 임의 지점에 설치하게 되므로 시공비를 증가시키고, 소요자재를 증가시키는 문제점이 있다.However, if the above devices are installed in a pipe, the pipes are installed at an arbitrary point by a separate joint pipe, thereby increasing the construction cost and increasing the required materials.

또한, 통상으로 도 1과 도 2와 같이 싱크대, 세면기, 양변기의 위생기연결구(2)와 이들과 연결하도록 급수관을 배관한 수전이음관(3) 사이는, 수전이음관(3)에 조절밸브(4)가 체결하고 이들이 연결되도록 가운데는 구부러져 휨이 가능하도록 물이 흐르는 관로(6)를 가진 고무호스(5)로 된 후, 고무호스(5) 외주를 금속망체(7)로 감싸 소정길이의 후렉시블관으로 된 후 양편 끝단에는 각각 일측에 돌출환턱(8)을 구비한 연결구(9)를 고무호스(5) 내주에 끼우고, 고정체(10)를 금속망체(7) 외주에 삽입 압축 고정한후 너트(11)를 후렉시블관에 장치하여 조절밸브(4)와 위생도기의 각각 위생기연결구(2) 나사에 가스켓(12)으로 씰링하도록 된 후렉시블연결관(1)을 체결배관하도록 사용하고 있다.Also, as shown in Figs. 1 and 2, between the sink, wash basin, and sanitary connector 2 of the toilet bowl, and the faucet joint pipe 3 piped with the water supply pipe to connect them, the faucet joint pipe 3 has a control valve ( 4) is fastened and the center is bent to form a rubber hose (5) having a conduit (6) through which water flows to allow bending, and then wraps the outer circumference of the rubber hose (5) with a metal mesh (7) of a predetermined length. After the flexible tube, both ends of the connector (9) having a protruding annulus (8) on each side is inserted into the rubber hose (5) inner circumference, and the fixing body (10) is inserted into the outer circumference of the metal mesh (7) After the nut 11 is installed on the flexible pipe, the flexible valve 1 is used to fasten and connect the flexible valve 1 to the screw of the sanitary connector 2 of the control valve 4 and the sanitary ware.

상기한 문제점을 해결하고자 하는 충격흡수장치를 가진 후렉시블연결관을 제안한 것이다.It is proposed a flexible connector having a shock absorbing device to solve the above problems.

이하 첨부한 도면을 참조하여 상세히 설명하면,Hereinafter, described in detail with reference to the accompanying drawings,

본 발명의 충격흡수장치를 가진 후렉시블연결관은 도3의 실시예와 도4의 고무호스(5)의 사시도와 같이 급수관과 통해 물이 흐르는 관로(6)를 가진 고무호스(5)가 금속망체(7)에 내장하되, 고무호스(5)의 관로(6) 외주와 외경사이 살두께부 길이부 방향으로 살두께 간에 다수개의 통공(20)을 구비한 구조로 되어, 상기와 같은 통공(20)에 공기층(21)이 형성하는 구조로 되었다.Flexible connection pipe having a shock absorbing device of the present invention is a metal hose is a rubber hose (5) having a pipe 6 through which water flows through the water supply pipe as shown in the embodiment of Figure 3 and the rubber hose (5) of Figure 4 It is built in (7), but has a structure having a plurality of through-hole 20 between the outer thickness and the outer diameter of the pipeline 6 of the rubber hose (5) in the direction of the flesh thickness portion, the through-hole as described above (20) ), The air layer 21 is formed.

이때 고무호스(5)는 물이 흐를 때 발생하는 압력이나 급수관의 정압에서는 팽창되지 않는 내력을 가졌지만 이보다 큰 압력, 즉 수도꼭지 밸브를 닫을때 발생하는 높은 압력파에서는 고무호스(5)의 살두께부를 압축하게 되면서 고무호스(5)는 관로(6)가 외주방향으로 팽창하여 관로(6)를 크게 하고, 동시에 통공(20)에 밀폐된 압축성인 공기가 충진된 공기층(21)이 압축하면서 비압축성인 물의 압력을 감쇄시키게 된다.At this time, the rubber hose (5) has a pressure that is generated when water flows or a static pressure that does not expand at a constant pressure of the water supply pipe, but the thickness of the rubber hose (5) at a higher pressure, that is, a high pressure wave generated when the faucet valve is closed. While compressing the portion, the rubber hose 5 expands the pipe 6 in the circumferential direction to enlarge the pipe 6, and at the same time, the air layer 21 filled with the compressible air sealed in the through hole 20 compresses and is incompressible. This will reduce the pressure of the phosphorus.

상기 고무호스(5)의 통공(20)은 후렉시블연결관(1)을 조립하는 공정에서 양단 내주에 연결구(9)를 삽입하여 금속망체(7) 외주의 고정체(10)로 압축고정할 때, 고무가 압축되면서 동시에 고무호스(5)의 통공(20)이 밀폐고정하던가 통공(20)의 양단을 밀폐하는 수단으로 양단 연결구(9) 길이정도로 된 통공(20)의 내경과 같은 씰링봉을 고무호스(5)의 양단 통공(20)에 삽입한 후, 고정체(10)와 연결구(9)를 이용 통공(20) 양단을 밀폐하면서, 통공(20)에 충진하였던 공기가 통공(20)에 밀폐되어 공기층(21)을 형성시킬 수 있다.When the through hole 20 of the rubber hose 5 is compressed and fixed to the fixed body 10 of the outer circumference of the metal mesh 7 by inserting the connector 9 into the inner circumference of both ends in the process of assembling the flexible connecting pipe 1. At the same time, the rubber is compressed and at the same time, the through hole 20 of the rubber hose 5 is sealed or fixed to both ends of the through hole 20. After the rubber hose 5 is inserted into the through hole 20 at both ends, the air filled in the through hole 20 is sealed while the both ends of the through hole 20 are closed by using the fixing body 10 and the connector 9. It is sealed in the air layer 21 can be formed.

상기의 충격흡수장치를 가진 후렉시블연결관은 별도의 충격흡수장치를 배관 중에 설치하지 않고, 배관중에 필요한 후렉시블연결관이 충격흡수장치를 가지면서 시공성과 경제성을 높이는 효과가 있다.The flexible connecting pipe having the shock absorbing device does not have a separate shock absorbing device installed in the pipe, and the flexible connecting pipe required in the pipe has a shock absorbing device, thereby improving construction and economic efficiency.
