Description

하수관용 역류방지밸브{A CHECK VALVE FOR A SEWER PIPE}Check valve for sewage pipes {A CHECK VALVE FOR A SEWER PIPE}

본 고안은 하수관용 역류방지밸브에 관한 것으로, 특히 유입구쪽을 맨홀쪽으로 돌출된 하수관에 끼운 경우에 쉽게 빠지지 않을 뿐만 아니라, 이물질이 유출구의 하부에 쌓이지 않게 되므로 개폐디스크가 확실하게 닫히는 한편, 유입구쪽의 두께가 얇아서 이물질이 유입구쪽에서 걸리지 않아 하수관을 통해 배출되는 하수와 오수가 원활하게 배출되도록 한 하수관용 역류방지밸브에 관한 것이다.
The present invention relates to a non-return valve for a sewage pipe, and in particular, when the inlet side is inserted into the sewer pipe protruding toward the manhole, it does not easily fall out, and foreign matter does not accumulate in the lower portion of the outlet, so that the opening / closing disk is closed securely, while the inlet side is closed. It is related with a non-return valve for sewage pipes so that the sewage and sewage discharged through the sewage pipes are smoothly discharged because the foreign substances are not caught at the inlet side because the thickness of the thin film is thin.

일반적으로 하수관용 역류방지밸브는 생활하수 등이 모여지는 맨홀과 광역하수도 사이의 하수관 대략 중앙에 고정설치되어 하수의 원활한 배출은 물론, 광역하수도를 통한 하수 또는 악취의 역류를 방지하도록 설치된다.In general, the backflow prevention valve for sewage pipe is fixedly installed in the center of the sewage pipe between the manhole where the local sewage is collected and the regional sewerage, and is installed to prevent the backflow of sewage or odor through the regional sewage as well as the smooth discharge of sewage.

이러한 역류방지밸브는 본 출원인에 의해 실용신안등록 제20-338590호로 제시된 하수관 및 기타 용수관용 역류방지밸브가 대표적인 것으로, 그 구성은 맨홀과 광역하수도 사이의 하수관 일측에 결합 고정되는 밸브몸체와, 상기 밸브몸체에 체결 고정되고 그 타측은 상기 하수관의 타측에 결합 고정되는 밸브커버와, 상기 밸브커버에 힌지핀으로 회동 가능하게 설치되어 내부의 유출통로를 선택적으로 개폐시키는 개폐디스크로 이루어 진다.Such a non-return valve is a representative of the non-return valve for sewage pipes and other water pipes presented in the Utility Model Registration No. 20-338590 by the present applicant, the configuration of the valve body is coupled to the sewage pipe between the manhole and the wide area sewer; It is fastened and fixed to the valve body and the other side is made of a valve cover coupled to the other side of the sewer pipe, and the opening and closing disk to be selectively opened and closed by the hinge pin on the valve cover to selectively open and close the outflow passage.

그런데, 이러한 종래 역류방지밸브는 맨홀과 광역하수도를 연결하는 하수관이 적정깊이의 지하에 매립되어 있으므로 역류방지밸브만 별도로 설치하기 위해서는 지면을 파내야하므로 과대한 비용이 소요되고, 역류방지밸브의 구성이 많은 구성부품으로 이루어지므로 제작과 조립공수 및 소요자재의 증가로 인해 원가가 상승함은 물론 잦은 고장을 유발한다는 등의 여러가지 결점들이 지적되고 있다.However, such a conventional non-return valve has an excessive cost because the sewer pipe connecting the manhole and the wide sewer is buried underground at an appropriate depth, so that only the non-return valve is installed in order to dig the ground. Since these components are made up of many components, various defects are pointed out such as an increase in costs and frequent failures due to an increase in manufacturing and assembly labor and required materials.

이러한 결점을 해소하기 위해 출원인에 의해 공개실용신안공보 공개번호 20-2008-0003907호로 하수관용 역지밸브가 제안되어 있는바, 개폐 경사부와 유출구가 플랜지의 일측면으로 돌출형성된 원통형 밸브몸체와, 상기 개폐 경사부에 착탈되도록 밸브몸체에 힌지 설치된 개폐디스크 및, 이들을 연결하는 힌지핀으로 구성되어 있다.In order to alleviate such drawbacks, the check valve for sewage pipes has been proposed by the applicant of the Korean Utility Model Publication No. 20-2008-0003907. The cylindrical valve body has an opening and closing slope and an outlet formed on one side of the flange. It consists of an opening and closing disk hinged to the valve body to be attached and detached to the opening and closing inclined portion, and a hinge pin connecting them.

따라서 상기 밸브몸체의 외면과 내면에는 각각 플랜지부와 개폐 경사부를 형성 시킴으로써 매설된 하수관 또는 정화조 등의 입구측 또는 출구측에 간편하게 고정 설치할 수 있어서 설치와 유지보수가 용이하고, 구성이 단순하여 제작과 조립원가를 최소화하며, 작동 신뢰성을 확보할 수 있다.Therefore, the outer and inner surfaces of the valve body can be easily fixed and installed on the inlet or outlet side of a sewage pipe or septic tank buried by forming a flange portion and an opening and closing inclined portion, respectively, so that the installation and maintenance are easy and the configuration is simple. Minimize assembly costs and ensure operational reliability.

그러나 이러한 하수관용 역류방지밸브는, 유입구쪽을 맨홀쪽으로 돌출된 하수관에 끼운 경우에 쉽게 빠지는 구조로 되어 있어서 하우징의 체결구멍을 이용하여 하우징을 맨홀쪽으로 돌출된 경우에 쉽게 빠지는 결점이 있다.However, such a backflow prevention valve for sewage pipes has a structure in which the inlet port is easily taken out when inserted into the sewer pipe protruding toward the manhole, and thus has a drawback of being easily released when the housing protrudes toward the manhole using the fastening hole of the housing.

또 상기 유출구의 상부는 물론 하부로 개폐 경사부 보다 길게 돌출되어 있어서 이물질이 유출구의 하부에 쌓이게 되면 개폐 경사부의 높이까지 올라오는 경우에 개폐디스크가 걸려서 확실하게 닫히지 않는 결점이 있다.In addition, the upper part of the outlet port, as well as the lower portion protrudes longer than the opening and closing inclined portion, if accumulated in the lower portion of the outlet, the opening and closing disc is caught in the case of rising to the height of the opening and closing portion there is a drawback that does not close securely.

또한 유입구쪽의 두께가 두꺼워서 이물질이 유입구쪽에서 걸리는 결점이 있고, 또 개폐 경사부의 파이프 두께도 두꺼워서 개폐디스크와 밀착되는 부위가 넓게 되므로실링이 잘 되지 않는 결점이 있다.
In addition, there is a defect that the foreign material is caught on the inlet side because the thickness of the inlet side is thick, and the pipe thickness of the opening and closing inclination portion is also thick, so that the area that is in close contact with the opening and closing disk is not good sealing.

본 고안은 상기와 같은 종래의 제반 결점을 해소하기 위해 안출된 것으로, 유입구쪽을 맨홀쪽으로 돌출된 하수관에 끼운 경우에 쉽게 빠지지 않을 뿐만 아니라, 상기 유출구의 하부는 개폐부 보다 짧게 돌출되어 있어서 이물질이 유출구의 하부에 쌓이지 않게 되므로 개폐디스크가 확실하게 닫히도록 된 하수관용 역류방지밸브를 제공함에 그 목적이 있다.The present invention is devised to solve the above-mentioned general drawbacks, not only does not fall easily when the inlet side is inserted into the sewer pipe protruding toward the manhole, the lower portion of the outlet is protruded shorter than the opening and closing the foreign matter outlet The purpose is to provide a non-return valve for the sewage pipe is to be closed so that the opening and closing disk is securely closed.

본 고안은, 유입구쪽의 두께가 얇아서 이물질이 유입구쪽에서 걸리지 않아 하수관을 통해 배출되는 하수와 오수가 원활하게 배출되도록 한 하수관용 역류방지밸브를 제공함에 그 목적이 있다.
The object of the present invention is to provide a non-return valve for sewage pipes so that the sewage and sewage discharged through the sewage pipes are smoothly discharged because the foreign material is not caught at the inlet side because the thickness of the inlet side is thin.

상기와 같은 목적을 달성하기 위한 본 고안의 하수관용 역류방지밸브는, 플랜지부를 경계로 양단에 유출구와 유입구가 형성된 밸브몸체와, 상기 밸브몸체의 유출구가 개폐되도록 힌지결합되는 개폐디스크를 포함하되, 상기 유입구의 외주면에는 하수구에 유입구의 외주면을 끼웠을 때 쉽게 빠지지 않도록 적도 한 쌍 이상으로 쐐기부가 구비된 것을 특징으로 한다.The backflow prevention valve for sewage pipes of the present invention for achieving the above object includes a valve body having an outlet and an inlet formed at both ends with a flange portion, and an opening / closing disk hinged to open and close the outlet of the valve body. The outer circumferential surface of the inlet is characterized in that the wedge portion is provided with at least one equator so as not to fall easily when the outer circumferential surface of the inlet is inserted into the sewer.

본 고안은, 상기 유출구측의 플랜지부의 하부에는 하수나 오수의 이물질이 적층되지 않도록 돌출되지 않고, 상기 플랜지부의 상부에만 플랜지부와 수직하게 일정길이 돌출되어 이물질이 개폐디스크를 오염시키지 못하도록 이물질유입방지부가 구비된 것을 특징으로 한다.The present invention does not protrude so that foreign substances of sewage or sewage are not laminated to the lower portion of the flange portion on the outlet side, and protrudes a certain length perpendicular to the flange portion only at the upper portion of the flange portion so that foreign substances do not contaminate the opening and closing disk. Characterized in that the inlet prevention portion is provided.

본 고안은, 상기 유입구의 파이프단부는 외주면으로 갈 수로 단면이 작아지도록 경사진 경사부가 형성된 것을 특징으로 한다.The present invention is characterized in that the inclined inclined portion is formed so that the pipe end portion of the inlet port to the outer circumferential surface becomes smaller.

본 고안은, 상기 유출구는 단부로 갈수록 단면이 작아지도록 개폐디스크밀착부가 형성된 것을 특징으로 한다.
The present invention, the outlet is characterized in that the opening and closing disk contact portion is formed so that the cross section is smaller toward the end.

이상 설명한 바와 같이 본 고안의 하수관용 역류방지밸브에 의하면, 유입구쪽을 맨홀쪽으로 돌출된 하수관에 끼운 경우에 쉽게 빠지지 않게 되는 효과가 있다.As described above, according to the backflow prevention valve for sewage pipe of the present invention, there is an effect that the inlet side is not easily pulled out when inserted into the sewer pipe protruding toward the manhole.

본 고안의 하수관용 역류방지밸브에 의하면, 상기 유출구의 하부는 개폐부 보다 짧게 돌출되어 있어서 이물질이 유출구의 하부에 쌓이지 않게 되므로 개폐디스크가 확실하게 닫히게 됨과 더불어 성형에 따른 사출재료의 감소로 제조비가 절감되는 효과가 있다.According to the backflow prevention valve for sewage pipe of the present invention, since the lower part of the outlet port is shorter than the opening and closing portion, foreign matter does not accumulate in the lower part of the outlet port, so that the opening and closing disk is closed securely, and the manufacturing cost is reduced due to the reduction of the injection material due to molding. It is effective.

본 고안의 하수관용 역류방지밸브에 의하면, 유입구쪽의 두께가 얇아서 이물질이 유입구쪽에서 걸리지 않아 하수관을 통해 배출되는 하수와 오수가 원활하게 배출되는 효과가 있다.
According to the backflow prevention valve for sewage pipe of the present invention, because the thickness of the inlet side is thin, foreign matter is not caught from the inlet side, and the sewage and sewage discharged through the sewer pipe are smoothly discharged.

이하에서는 첨부된 도면을 참조하여 본 고안의 바람직한 실시예에 대해서 설명한다.Hereinafter, with reference to the accompanying drawings will be described a preferred embodiment of the present invention.

본 고안의 하수관용 역류방지밸브(100)는 도 1 내지 도 6에 도시된 것과 같이, 플랜지부(111)를 경계로 양단에 유출구(112)와 유입구(113)가 형성된 밸브몸체(110)와, 상기 밸브몸체(110)의 유출구(112)가 개폐되도록 힌지부(130)로 힌지결합되는 개폐디스크(120)를 포함한다.Sewage pipe backflow prevention valve 100 of the present invention, as shown in Figures 1 to 6, the valve body 110 and the outlet 112 and the inlet 113 is formed at both ends of the flange portion 111 boundary and And, the outlet 112 of the valve body 110 includes an opening and closing disk 120 hinged to the hinge portion 130 to open and close.

여기서 상기 플랜지부(111)의 외주면에는 하수구 또는 맨홀에 밸브몸체(110)를 보울트와 나사못등으로 고정하기 위해 구멍이 형성된 밸브몸체고정부(111a)가 형성된다.Here, the valve body fixing part 111a having a hole is formed on the outer circumferential surface of the flange 111 to fix the valve body 110 to the sewer or the manhole with bolts and screws.

또 상기 플랜지부(111)의 상부에는 힌지부(130)의 후술하는 체결수단(132)을 구성하는 보울트가 끼워지는 구멍(111b)이 형성되고, 이 구멍의 가까운 곳에는 힌지부가 회동되는 것을 방지하도록 회전방지홈(111c)이 형성된다.In addition, the upper portion of the flange portion 111 is formed with a hole 111b into which the bolt constituting the fastening means 132 of the hinge portion 130 to be described later is formed, and the hinge portion is prevented from being rotated near the hole. The anti-rotation groove 111 c is formed.

그리고 상기 유입구(113)의 외주면에는 하수구에 유입구(113)의 외주면을 끼웠을 때 쉽게 빠지지 않도록 적도 한 쌍 이상으로 쐐기부(113a)가 구비된다.And the outer circumferential surface of the inlet 113 is provided with a wedge portion 113a at least a pair of equator so as not to fall easily when the outer circumferential surface of the inlet 113 is inserted into the sewer.

따라서 상기 유입구(113)를 하수구의 하수관에 내주면으로 끼우게 되면 상기 쐐기부(113a)에 의해 들어갈 때는 쉽게 들어가게 되지만 뺄때는 쐐기부의 쐐기방향에 의해 쉽게 빠지지 않게 되므로 역류방지밸브가 맨홀로 빠져서 역류방지밸브의 역할을 할 수 없도록 되는 것을 한 층 방지할 수 있게 된다.Therefore, when the inlet 113 is inserted into the sewer pipe of the sewer as the inner circumferential surface is easily entered when entering by the wedge portion (113a), but when pulled out is not easily pulled out by the wedge direction of the wedge portion, so the non-return valve prevents the flow back It is possible to further prevent the valve from serving as a valve.

상기 쐐기부(113a)는 유입구의 외주면 보다 얇게 되도록 도피홈(113b)이 쐐기부(113a)의 주위에 형성되어 쐐기부가 탄력적으로 유동되도록 형성된다.The wedge portion 113a is formed so that the escape groove 113b is formed around the wedge portion 113a so as to be thinner than the outer circumferential surface of the inlet so that the wedge portion elastically flows.

따라서 상기 도피홈(113b)에 의해 탄력적으로 쐐기부(113a)가 유동되므로 하수구의 하수관에 역류방지밸브(100)의 밸브몸체(110)를 용이하게 밀어 넣을 수 있게 된다. 물론 상기 유입구(113)의 외주면에 접착재를 도포하고 하수관에 끼우게 되면 분해가 되지 않게 할 수 있으나, 상기 쐐기부(113a)에 의해 맨홀의 하수관에서 역류방지밸브(100)를 분실하지 않으면서도 유지보수가 매우 용이하게 되었다.Therefore, the wedge portion 113a flows elastically by the escape groove 113b, so that the valve body 110 of the non-return valve 100 can be easily pushed into the sewer pipe of the sewer. Of course, if the adhesive is applied to the outer circumferential surface of the inlet 113 and inserted into the sewer pipe can be prevented from being disassembled, but maintained without losing the backflow prevention valve 100 in the sewer pipe of the manhole by the wedge (113a) The maintenance became very easy.

상기 유입구(113)의 파이프형상 단부는 외주면으로 갈 수로 단면이 작아지도록 경사진 경사부(113c)가 형성된다.The pipe-shaped end portion of the inlet 113 is inclined to form an inclined portion (113c) so that the cross section is small to go to the outer peripheral surface.

따라서 상기 경사부(113c)에 의해 하수관으로 부터 배출되는 오수나 하부의 이물질이 유입구(113)에 걸리지 않게 되어 장마시에 유량이 증대하고 배출이 용이하게 되는 효과가 있게 된다.Therefore, the sewage discharged from the sewage pipe by the inclined portion 113c or foreign substances in the lower portion is not caught in the inlet 113, so that the flow rate increases during rainy season and the discharge is easy.

또한 상기 유출구(112)측의 플랜지부(111)의 하부에는 하수나 오수의 이물질이 적층되지 않도록 돌출되지 않고, 상기 플랜지부(111)의 상부에만 플랜지부와 수직하게 일정길이 돌출되어 상부로 부터 떨어지는 이물질에 의해 개폐디스크(120)를 오염시키지 못하도록 이물질유입방지부(114)가 구비된다.In addition, the lower portion of the flange portion 111 on the outlet 112 side does not protrude so that foreign substances of sewage or sewage are not laminated, and a predetermined length is vertically protruded from the upper portion only in the upper portion of the flange portion 111. The foreign matter inflow prevention part 114 is provided so that the opening / closing disc 120 may not be contaminated by falling foreign matter.

즉, 상기 이물질유입방지부(114)가 플랜지부(111)의 상부에만 형성되어 개폐디스크(120)의 오염을 상부는 물론 하부로 부터의 오염도 방지할 수 있게 된다.That is, the foreign matter inflow prevention part 114 is formed only on the upper portion of the flange portion 111 to prevent the contamination of the opening and closing disk 120 from the top as well as the contamination from the bottom.

상기 이물질유입방지부(114)에는 상기 힌지부(130)의 힌지핀(133)이 끼워지도록 안내하는 힌지핀안내홈(114a)이 슬롯 또는 원형의 형태로 형성된다. The foreign material inflow prevention part 114 has a hinge pin guide groove 114a for guiding the hinge pin 133 of the hinge part 130 to be inserted into a slot or a circular shape.

따라서 상기 힌지핀안내홈(114a)으로 힌지핀(133)의 조립이 매우 용이하게 된다.Therefore, assembling of the hinge pin 133 into the hinge pin guide groove 114a becomes very easy.

상기 유출구(112)는 단부로 갈수록 단면이 작아지도록 개폐디스크밀착부(112a)가 형성된다. 또 도 2에서와 같이 단부에는 계단져 확경시켜 상기 개폐디스크밀착부(112a)가 조절될 수 있다.The outlet 112 has an opening and closing disk contact portion 112a is formed so that the cross section is smaller toward the end. In addition, the opening and closing disk contact portion 112a may be adjusted by expanding the stepped portion as shown in FIG. 2.

따라서 상기 개폐디스크밀착부(112a)에 의해 개폐디스크(120)와 밀착되는 면이 적어서 오염 물질이 개폐디스크밀착부(112a)에 붙지 않게 되므로 개폐디스크가 개폐디스크밀착부에 잘 밀착되므로 악취가 역류하는 것을 한층 방지할 수 있게 된다.Therefore, since the surface close to the opening and closing disk 120 by the open and close disk contact portion 112a is less contaminants do not adhere to the open and close disk contact portion 112a, the open and close disk close contact with the open and close disk contact portion, so the odor is reversed. It becomes possible to prevent further.

상기 유출구(112)는 축방향으로 상부보다 하부의 길이가 길게 형성된 개폐경사면(112b)이 형성된다.The outlet 112 has an opening and closing slope 112b formed to have a longer length than a top portion in the axial direction.

따라서 상기 개폐디스크(120)가 자중에 의해 내려갈 때 개폐경사면(112b)과 밀착력이 한층 증대되어 냄새등의 역류가 방지된다.Therefore, when the opening and closing disk 120 is lowered by its own weight, the adhesion force to the opening and closing slope 112b is further increased to prevent backflow such as smell.
