Description

하수도 맨홀용 역지변 {Check valve for manhole}Check valve for manhole}

본 발명은 하수도 맨홀로 유입될 우수 혹은 오수와 함께 맨홀 내에서 발생하는 악취의 역류를 방지하는 역지변에 관한 것이다.The present invention relates to a reverse displacement that prevents backflow of odors occurring in the manhole with rainwater or sewage to be introduced into the sewer manhole.

일반적으로 매립되어 있는 하수도의 대부분은 우수/오수가 함께 유입되어 흐르는 합류식관으로 이루어져 있어, 하수도 맨홀을 통해서 외부로 유출되는 심한 악취가 유출되어 일상 생활을 영위하기 어려울 때가 종종 발생한다.In general, most of the sewage in the landfill is composed of a conduit pipe flowing with rainwater / sewage flowing together, and it is often difficult to carry out daily life due to the outflow of bad odor that flows out through the sewer manhole.

이러한 불편함을 해소하기 위해, 시민들은 임시방편으로 맨홀에 장판을 하수도 맨홀 위에 덮어씌워 하수도 내부에서 발생하는 악취가 외부로 누출되는 현상을 방지할 수는 있다. 하지만, 이러한 장판은 우천시 맨홀로 비가 배수되지 못하여 주변의 침수원인을 제공할 뿐만 아니라 환절기 혹은 여름에 장판과 맨홀 사이의 틈새로 매우 불쾌한 악취가 유출되는 문제점을 갖는다.To alleviate this inconvenience, citizens can temporarily cover the manholes with sewer manholes over the sewer manholes to prevent odors from occurring inside the sewers. However, such a floor plate has a problem that the rain can not be drained to the manhole during rainy weather and provides a cause of flooding, as well as a very unpleasant odor leaked into the gap between the floorboard and the manhole during the season or summer.

특히, 생활변화와 기후변화로 인하여 생활하수의 양이 증가되어 하수도의 악취로 인한 민원이 빈번하게 야기되고, 파리, 모기 등과 같은 유해한 해충의 서식지 로 되어 도시민의 건강을 위협할 수 있다. In particular, the amount of domestic sewage is increased due to changes in living and climate change, causing civil complaints due to the smell of sewage, and becoming a habitat for harmful pests such as flies and mosquitoes, which can threaten the health of urban residents.

또한, 현재 사용되고 있는 하수도 맨홀은 많은 양의 하수가 흐르게 될 경우 맨홀을 관통하여 도심지의 도로변으로 역류하는 현상을 목격할 수 있을 것이다.In addition, the sewage manhole that is currently used will be able to witness the phenomenon of flowing back through the manhole to the roadside of the city when a large amount of sewage flows.

이러한 하수도 맨홀에서 발생하는 문제점을 해결하기 위해서, 본 발명에 따른 역지변이 제공된다.In order to solve this problem occurring in the sewer manhole, a reverse displacement according to the present invention is provided.

본 발명의 목적은 하수도 맨홀 속으로 우수 혹은 오수가 유입되면 자동개폐구를 개방하는 한편, 이러한 물의 유입이 없을 시에는 자동개폐구가 폐쇄되도록 한다.An object of the present invention is to open the automatic switchgear when rainwater or sewage flows into the sewer manhole, while the automatic switchgear is closed when there is no inflow of water.

본 발명의 목적은 하수구 내에서 부패 물질로 발생하는 일정한 압력 이상의 압력가스는 공기변을 통해 외부로 방출되도록 되어 있다.An object of the present invention is to discharge pressure gas above a certain pressure generated as a decay material in the sewer to the outside through the air valve.

또한, 본 발명은 상기와 같은 목적을 성취하기 위해서 별도의 설비를 추가로 장착할 필요가 없이 단순히 맨홀과 맨홀 뚜껑 사이에 삽입시켜 위치시키면 된다.In addition, the present invention does not need to be additionally equipped in order to achieve the above object, it is merely to be inserted and positioned between the manhole and the manhole cover.

본 발명의 목적은 전술되었듯이 맨홀과 맨홀 뚜껑 사이에 위치된 본 발명의 역지변을 매개로 하여 맨홀과 맨홀 뚜껑 사이의 틈새로 유출되던 악취를 완전하게 차단하도록 되어 있다.The object of the present invention is to completely block the odor that has leaked into the gap between the manhole and the manhole cover through the reverse displacement of the present invention located between the manhole and the manhole cover as described above.

이상 본 발명의 설명에 의하면, 본 발명은 하수도관 내의 맨홀에서 발생하는 악취를 완전하게 외부로 유출되는 것을 차단하여 친환경적인 도시 환경을 조성할 수 있다.According to the description of the present invention, the present invention can block the outflow of odor generated in the manhole in the sewer pipe to the outside completely to create an environment-friendly urban environment.

이와 더불어서, 본 발명은 하수의 역류를 방지할 수 있게 되어 있다.In addition, the present invention can prevent backflow of sewage.

본 발명은 필요시에만 하수와 가스의 흐름을 제공하므로 통상적으로 파리와 모기 등의 해충이 기생할 수 있는 여건을 차단할 수 있어 도시민의 전염병을 예방할 수도 있다.Since the present invention provides a flow of sewage and gas only when necessary, it is possible to block the conditions in which pests such as flies and mosquitoes can be parasitic, thereby preventing the infectious diseases of urban residents.

또한, 본 발명에 따른 역지변은 기존 하수도 맨홀을 교체하거나 별도의 설비를 추가하지 않고서도 맨홀과 맨홀 뚜껑 사이에 안착시키기만 하면 되어 작업공수를 현저하게 줄이고 시공시간뿐만 아니라 설치비용을 저감시켜 조속히 확대 보급시킬 수 있는 장점을 제공한다.In addition, the reverse displacement according to the present invention is to be placed between the manhole and the manhole cover without replacing the existing sewer manhole or adding additional equipment, significantly reducing the labor and construction time as well as reducing the installation cost as soon as possible It offers the advantage of being expanded.

이제, 첨부도면을 참조로 하여 본 발명에 따른 하수도 맨홀용 역지변에 대해서 더욱 상세히 설명할 것이다.Now, with reference to the accompanying drawings will be described in more detail with respect to the reverse displacement for the sewer manhole according to the invention.

도 1은 본 발명에 따른 하수도 맨홀용 역지변의 단면도이다.1 is a cross-sectional view of the reverse ground for sewer manhole according to the present invention.

도시된 바와 같이, 본 발명에 따른 하수도 맨홀용 역지변(1)은 맨홀 뚜껑(101)과 하수도관의 맨홀(102) 사이에 배치된다.As shown, the stationary side 1 for the sewer manhole according to the invention is disposed between the manhole cover 101 and the manhole 102 of the sewer pipe.

하수도 맨홀용 역지변(1)은 아래를 향해 볼록형상의 만곡부(10)로 형성되되, 특히 맨홀 뚜껑(101)과 맨홀(102) 사이에 배치되기 위해 얇게 되어 있다.The stationary side edge 1 for the sewer manhole is formed with a convex curved portion 10 downward, and is particularly thin to be disposed between the manhole cover 101 and the manhole 102.

특히, 우수 또는 하수 등이 맨홀(101)의 배수구(103)를 통해 맨홀(102) 내로 유입된다. 유입된 하수는 볼록형상으로 이루어진 역지변(1)의 만곡부(10) 중심으로 집중되고, 이러한 하수는 자동개폐구(A)를 수단으로 하여 하수도관으로 흘러들어간다.In particular, rainwater or sewage is introduced into the manhole 102 through the drain hole 103 of the manhole 101. The introduced sewage is concentrated at the center of the curved portion 10 of the convex inverted edge 1, and the sewage flows into the sewer pipe by means of the automatic opening and closing hole A.

또한, 본 발명에 따른 역지변(1)은 하수도관에서 발생하는 일정한 압력 이상의 압력가스가 발생하게 되면 공기변(B)이 개방되어 맨홀 뚜껑(101)의 배수구(103)를 통과하여 외부로 배출되도록 설계되어 있다. In addition, the reverse side (1) according to the present invention, when a pressure gas of a predetermined pressure or more generated in the sewer pipe is generated, the air valve (B) is opened to discharge through the drain hole 103 of the manhole cover 101 to the outside It is designed to be.

덧붙여서, 본 발명에 따른 역지변(1)은 그 가장자리는 밀폐용 패킹재(11)를 구비한다. 이러한 밀폐용 패킹재(11)는 맨홀 뚜껑(101)과 맨홀(102) 사이에 위치되어 역지변(1)의 설치를 위한 별도의 설비를 요구하지 않으며 특히 맨홀 뚜껑(101)과 맨홀(102) 사이로 악취가 배출되는 것을 방지한다.In addition, the reverse finger 1 according to the present invention has a sealing member 11 for sealing at its edge. The sealing packing material 11 is located between the manhole cover 101 and the manhole 102 does not require a separate facility for the installation of the station 1, in particular the manhole cover 101 and the manhole 102 Prevents odors from leaking out between them.

자동개폐구(A)는 역지변(1)의 중심에 위치되는 것이 바람직하다. 이는 아래방향을 향해 볼록형상으로 되어 있는 만곡부(10)로 유입된 하수 등의 물이 집결되기 용이하도록 한다. 자동개폐구(A)는 역지변(1)에 흐름경로(A1)와 이 흐름경로(A1) 하단에 힌지식 도어(A2)를 구비한다. 힌지식 도어(A2)는 평상시, 구체적으로 물의 유입이 없을 때에는 흐름경로(A1)를 차단(점선으로 표시)한다. 이렇게 폐쇄된 힌지식 도어(A2)는 하수도관 내부에서 발생하는 악취를 외부로 배출되는 것을 방지할 뿐만 아니라 이와 함께 하수도관 내부로 흐르는 유수가 맨홀(101)로 역류되는 것을 방지하도록 한다.Automatic opening and closing opening (A) is preferably located at the center of the reverse side (1). This facilitates the collection of water such as sewage introduced into the curved portion 10 that is convex toward the downward direction. The automatic opening / closing opening (A) has a flow path (A1) at the reverse side (1) and a hinged door (A2) at the bottom of the flow path (A1). The hinged door A2 normally blocks the flow path A1 (indicated by the dotted line) when there is no inflow of water. The closed hinged door A2 prevents the odor generated in the sewer pipe from being discharged to the outside, and also prevents the flowing water flowing into the sewer pipe back into the manhole 101.

이와는 반대로 힌지식 도어(A2)는 우천시, 구체적으로 맨홀(101)의 배수구(103)로 다양한 하수가 유입될 때에 흐름경로(A1)를 개방(실선으로 표시)한다. 맨홀(101)의 배수구(103)로 유입된 하수는 만곡부(10)를 따라 그 중심으로 집결되고서는, 흐름경로(A1)를 통과하여 힌지식 도어(A2)를 물의 중량으로 밀어부쳐 개방시키도록 되어 있다. On the contrary, the hinged door A2 opens (indicated by a solid line) the flow path A1 in rainy weather, specifically when various sewage flows into the drain hole 103 of the manhole 101. The sewage flowing into the drain hole 103 of the manhole 101 is collected at its center along the curved portion 10, and then passes through the flow path A1 to push the hinged door A2 to the weight of water to open. It is.

선택가능하기로, 힌지식 도어(A2)의 한 단부에 무게추(A3)를 갖춰 흐름경로(A1)를 타고 힌지식 도어(A2)를 가압하지 않을 때에 힌지식 도어(A2)를 평행하게, 바람직하게는 흐름경로(A1)를 폐쇄할 수 있게 무게중심작용을 하도록 한다. 전술되었듯이, 흐름경로(A1)로 물이 흐르면 힌지식 도어(A2)의 무게중심이 흐트러져 도어가 개방되고 물이 다 하수도관으로 흘러 내려가면 무게추(A3)의 무게로 다시 힌지식 도어(A2)는 원위치(폐쇄)로 복귀하도록 한다.Optionally, the hinged door A2 is arranged in parallel when the weight A3 is provided at one end of the hinged door A2 so as not to press the hinged door A2 in the flow path A1. Preferably the center of gravity action to close the flow path (A1). As described above, when water flows through the flow path A1, the center of gravity of the hinged door A2 is disturbed, and the door is opened, and when the water flows down to the sewer pipe, the hinged door ( A2) returns to the original position (closed).

본 발명에 따른 역지변(1)은 공기변(B)을 추가로 구비하는 것을 특징으로 한다.Reverse valve 1 according to the invention is characterized in that it further comprises an air valve (B).

이러한 공기변(B)은 만곡부(10)에 구비되되, 서로 대향되게 입구(B4)와 출구(B5)를 구비한 하우징(B1)과, 볼(B2) 및, 스프링(B3)으로 이루어져 있다. 바람직하게는 입구(B4)는 만곡부의 하부, 즉 하수도관으로 배치되는 한편, 출구(B5)는 만곡부(10)의 상부, 즉 맨홀 뚜껑(101)을 향해 배치되게 한다.The air valve B is provided in the curved portion 10, and consists of a housing B1 having an inlet B4 and an outlet B5 facing each other, a ball B2, and a spring B3. Preferably the inlet B4 is arranged at the bottom of the bend, ie the sewer pipe, while the outlet B5 is arranged at the top of the bend 10, ie towards the manhole cover 101.

평상시와 같이, 공기변(B)은 맨홀 내부에 일정 압력 이후의 가스로 채워져 있을 때에는, 더욱 구체적으로 스프링(B3)을 가압할 수 없는 정도의 압력으로 채워져 있을 때에는 볼(B2)이 입구(B4)를 폐쇄하고 있어 내부공기가 외부로 빠져나가지 못하게 한다. As usual, when the air valve B is filled with gas after a certain pressure inside the manhole, more specifically, when the spring B3 is filled with a pressure such that the spring B3 cannot be pressurized, the ball B2 enters the inlet B4. ) To prevent internal air from escaping.

하수도관에 일정 압력 이상의 압력가스가 발생하게 되면, 압력가스가 입구(B4) 위에 올려져 있는 볼(B2)을 가압하게 되고, 일정 압력 이상의 힘으로 볼(B2)을 가압하면 스프링(B3)이 수축되어 볼(B2)이 출구(B5)보다 높게 위치변동되어 압력가스는 외부로 배출될 수 있게 한다. 이러한 압력가스는 맨홀 뚜껑(101)을 열게 하는 등 사고 위험을 내재하고 있다. 이러한 문제점을 극복하기 위해서, 본 발명은 공기변(B)을 구비한다.When a pressure gas of a predetermined pressure or more is generated in the sewer pipe, the pressure gas pressurizes the ball B2 placed on the inlet B4. When the pressure of the ball B2 is applied by a force of a predetermined pressure or more, the spring B3 By contracting, the ball B2 is shifted higher than the outlet B5 so that the pressure gas can be discharged to the outside. This pressure gas has an accident risk such as opening the manhole cover 101. In order to overcome this problem, the present invention includes an air valve (B).
