Abstract

PURPOSE: A water hammer preventing device largely reduces the number of assembling parts, lowers the manufacturing cost, needs not the special repair and maintenance and prominently absorbs the water hammer inside a pipeline. CONSTITUTION: A water hammer preventing device includes a ball housing(50), an absorbing device and a supporting device. The ball housing(50) connected between a pipeline(P) has a fluid inlet(51) at one end side thereof and a fluid outlet(52) at the other end side thereof. The absorbing device positioned in the ball housing(50) separately absorbs the pressure rise of the pipeline(P) simultaneously. The supporting device makes the absorbing device be positioned inside the ball housing(50) and is formed of the mesh structure(60). The absorbing device is composed of many buffering balls(70) made from rubber. The buffering ball(70) is arrayed between the inner wall of the ball housing(70) and the mesh structure(60). The buffering ball(70) is in contact with both.

본 발명은 관로에 설치되어 유로가 급속히 차단되었을 때 발생되는 햄머현상을 방지하기 위한 워터 햄머 방지장치에 관한 것으로, 특히 다수의 완충용 볼을 갖는 볼 하우징을 관로에 직결 조립되도록 하여 설치가 용이하고 구조가 간단하면서도 내구 성능이 우수한 워터 햄머 방지장치에 관한 것이다.The present invention relates to a water hammer prevention device installed in the pipeline to prevent the hammer phenomenon caused when the flow path is rapidly blocked, in particular, easy to install the ball housing having a plurality of buffer balls directly assembled to the pipeline. The present invention relates to a water hammer prevention device having a simple structure and excellent durability.

일반적으로 관로에는 유체의 흐름을 급격히 차단할 경우 발생되는 수격 (water hammer)으로 인해 소음이 발생되고, 관로의 파손을 가져오게 된다.In general, in the pipeline, noise is generated due to a water hammer generated when the flow of fluid is cut off rapidly, resulting in breakage of the pipeline.

따라서 종래에는 관로의 중간에 가스가 주입된 용기를 연결 사용하거나, 가스와 스프링 및 피스톤을 함께 이용한 완충장치를 사용하여 이를 해결하였다.Therefore, in the related art, this is solved by using a container in which gas is injected in the middle of a pipeline, or using a shock absorber using a gas, a spring, and a piston together.

그런데 가스를 사용하는 장치에 있어서는, 수격으로 인한 면압 흡수 효율이 떨어지고, 수격방지 용량에 따라 용기의 크기가 커지는 단점을 가지고 있다.By the way, in the apparatus using the gas, the surface pressure absorption efficiency due to the water hammer is inferior, and the size of the container according to the water hammer prevention capacity has a disadvantage.

또, 가스와 스프링 및 피스톤을 사용하는 경우에는 피스톤의 사용상태가 많을수록 내구성이 떨어져 작동의 신뢰성이 떨어지는 단점을 가지고 있다.In addition, in the case of using a gas, a spring and a piston, the more the use state of the piston, the lower the durability and the disadvantage of inferior reliability.

이외에 관로에 직열로 설치되어 기계적인 메카니즘으로 작동하는 수격흡수장치가 있으나 이는 제작이 복잡하고 설치비용을 상승시키는 단점을 가지고 있다.In addition, there is a water-absorbing device installed in the pipeline in series with a mechanical mechanism, but this has a disadvantage in that the manufacturing is complicated and the installation cost is increased.

따라서 본 발명은 상기와 같은 사정을 감안하여 창안된 것으로, 조립부품수를 대폭 줄이면서 제작비용을 낮추고 별도의 보수 유지가 필요 없으면서, 관로내의 수격흡수가 뛰어난 워터 햄머 방지장치를 제공함에 그 목적이 있다.Therefore, the present invention was devised in view of the above circumstances, and the object of the present invention is to provide a water hammer prevention device having excellent water absorption in the pipeline without significantly reducing the number of assembly parts and lowering the manufacturing cost and requiring maintenance. have.

상기의 목적을 달성하기 위한 본 발명의 구체적인 수단은,Specific means of the present invention for achieving the above object,

관로(P)에 설치되어 워터 햄머 현상을 방지하기 위한 장치에 있어서,In the device for preventing the water hammer phenomenon installed in the pipeline (P),

이하, 첨부된 도면을 참조하여 본 발명의 실시예를 상세히 설명한다.Hereinafter, with reference to the accompanying drawings will be described an embodiment of the present invention;

도 1은 본 발명의 실시예에 따른 워터 햄머 방지장치가 관로에 설치된 단면도이고, 도 2는 도 1의 A-A선에서 본 단면확대도이다.1 is a cross-sectional view of the water hammer prevention apparatus according to an embodiment of the present invention installed in the conduit, Figure 2 is an enlarged cross-sectional view seen from the line A-A of FIG.

도 1,2에 도시된 바와 같이 관로(P)의 중간에 직결식으로 볼 하우징(50)이 접속되어 있고, 상기 볼 하우징(50)은 일측에 유체 입구(51)를 갖고 타측에 유체 출구(52)를 갖으며, 본 실시예에서 볼 하우징(50)의 직경은 관로(P)의 직경보다 대략 2배로 크며 그 길이는 직경의 대략 4배로 설정되어 있다.As shown in FIGS. 1 and 2, the ball housing 50 is connected directly to the middle of the conduit P. The ball housing 50 has a fluid inlet 51 on one side and a fluid outlet on the other side. 52), the diameter of the ball housing 50 in this embodiment is approximately twice as large as the diameter of the conduit P and the length is set to approximately four times the diameter.

상기 볼 하우징(50)의 내측에는 후술한 완충용 볼(70)을 볼 하우징(50)의 내측 둘레 배열지지시키기 위한 지지수단으로 망체(60)가 조립되어 있다.Inside the ball housing 50, the mesh 60 is assembled as a supporting means for supporting the buffer ball 70 described later, arranged in the inner circumference of the ball housing 50.

상기 완충용 볼(70)은 지지수단인 망체(60)에 의해 상기 볼 하우징(50)내에서 위치하여 관로(P)의 압력상승을 흡수하는 흡수수단으로, 고무재로 형성되어 있다.The buffer ball 70 is an absorbing means positioned in the ball housing 50 by the mesh 60 as a supporting means and absorbing the pressure rise of the pipe line P, and is formed of a rubber material.

즉, 상기 완충용 볼(70)은 상기 볼 하우징(50)의 내벽과 망체(60)의 사이에서 망체(60)의 둘레로 배열되어 서로 접촉되게 위치하고 있다.That is, the buffer ball 70 is arranged in contact with each other arranged around the mesh 60 between the inner wall of the ball housing 50 and the mesh 60.

이와 같이 구성된 본 실시예의 워터 해머 방지장치에서 볼 하우징(50)은 일체로서 구성되어 있으나 볼 하우징(50)내에 망체(60) 및 완충용 볼(70)을 조립하기 위해서 분리형으로 제작된다.In the water hammer prevention device of the present embodiment configured as described above, the ball housing 50 is configured as a single body, but is manufactured in a separate type to assemble the mesh 60 and the buffer ball 70 in the ball housing 50.

그리고 분리된 볼 하우징(50)은 망체(60)와 완충용 볼(70)을 조립한 다음 용접을 이용하여 일체로 접합시킨다.Then, the separated ball housing 50 assembles the mesh 60 and the buffer ball 70 and then integrally bonds them by welding.

그러나 본 발명은 용접을 이용하는 방법 이외에 분리된 볼 하우징(50)의 접합부분에 플랜지를 형성시키고, 플랜지들 사이에 실링을 하여 체결수단인 볼트로 연결시키는 방법도 있다.However, in the present invention, there is also a method of forming a flange at the joint of the separated ball housing 50 in addition to the method of welding, and sealing the flanges to connect the bolts as fastening means.

또 다른 방법으로 볼 하우징의 전단된 부분을 나사결합으로 접속 구성하여도 좋다.Alternatively, the sheared portion of the ball housing may be screwed together.

이와 같이 구성된 본 발명은 작용을 설명한다.The present invention thus constructed illustrates the operation.

먼저, 관로(P)에 일정한 유량(Q)이 흘러가게 되면 유속과 압력을 갖게 된다.First, when a constant flow rate (Q) flows into the pipe line (P) has a flow rate and pressure.

이같은 상태에서 볼 하우징(50)의 출구(52)측에서 유량의 흐름을 급속히 차단하게 되면 순간적으로 압력상승이 발생된다.In such a state, if the flow of the flow rate is rapidly cut off at the outlet 52 side of the ball housing 50, a pressure increase occurs momentarily.

따라서 압력상승으로 인한 충격에너지가 볼 하우징(50)내에 채워져 있는 다수의 완충용 볼(70)에 전달되고, 완충용 볼(70)은 충격에너지에 의해 순간적으로 탄성변형되면서 이 충격에너지를 흡수하게 된다.Therefore, the impact energy due to the pressure increase is transmitted to a plurality of buffer balls 70 filled in the ball housing 50, the buffer ball 70 is absorbed by the impact energy while being elastically deformed instantaneously. do.

따라서 관로(P)는 급작한 유량의 차단으로 발생된 충격에너지로부터 안전하게 되어 파손의 염려가 없고, 소음도 발생되지 않는 것이다.Therefore, the pipe P is secured from the impact energy generated by the sudden interruption of the flow rate, and there is no fear of damage, and no noise is generated.

상술한 바와 같이 본 발명에 의하면, 관로에 직결되는 볼 하우징을 구비하고, 볼 하우징내에 충격에너지의 흡수가 용이한 완충용 볼을 사용하여 워터 해머 방지의 효과가 뛰어나다.As described above, according to the present invention, the water hammer prevention effect is excellent by using a buffer ball which is provided with a ball housing directly connected to the conduit and easily absorbs shock energy in the ball housing.

특히, 구성이 간단하고 조립이 용이하여 내구성이 뛰어나고 보수 및 유지 비용의 염려가 없는 장점을 갖는다.In particular, the configuration is simple and easy to assemble has the advantages of excellent durability and no worry about maintenance and maintenance costs.
