Abstract

The apparatus introduces air into a drain conduit in order to prevent the formation of vacuum in the conduit. The apparatus includes an actuation disc (10), a circular hed (20) and a cover (30). The actuation disc (10) opens vertical ventilation holes (23) of the circular head (20) when a sufficient level of vacuum is formed within the conduit, and the disc (10) closes the ventilation holes (23) when the vacuum within the conduit is dissipated. The conduit is maintained in a water-tight condition owing to the existence of a circular disc (14).

본 발명은 폐수를 배출하는 배수관 또는 배수관에 연결된 가지관둥의 내부에서 진공상태가 발생하였을 경우 자동적으로 배수관에 공기를 유입시켜 진공상태가 되는 것을 방지하고 진공상태가 제거되면 공기의 유입을 차단시켜 밀봉되어 있는 상태가 되도록하여 주는 것이다. 만약 배수관 내(內)가 진공상태로 되어 있는 경우에는 각 가지관으로부터 배수관에 유입되는 폐수의 배출을 원활하게 유지시킬 수가 없으며 배수관내에 공기의 유입이 없었을 경우에는 폐수의 배출이 역류될 정도로 부분 압력이 상승하게 되며 이럴 경우 하수구로 부터의 악취가 오히려 실내로 유입되는 폐단도 배제할 수는 없을 것이다.The present invention prevents the vacuum state by introducing air into the drain pipe automatically when a vacuum condition occurs in the drain pipe for draining waste water or the branch pipe connected to the drain pipe, and blocking the inflow of air when the vacuum condition is removed. It is to be in a state of being. If the drain pipe is in a vacuum state, it is impossible to maintain the discharge of the wastewater flowing into the drain pipe from each branch pipe smoothly. If there is no air inflow into the drain pipe, the partial pressure is enough to reverse the discharge of the waste water. This rises, and in this case, the odor from the sewers will not be able to exclude the entrance into the room.

본 발명은 상술한 바와 같은 제방 문제점을 해결하는 특성이 있는 것으로서 첨부 도면에 의거 설명하고자 한다.The present invention is to be described based on the accompanying drawings as having the characteristics to solve the embankment problem described above.

제1도는 본 발명에 분해 사시도로서, 덮개(30)의 내측 중앙에는 안내봉(31)이 축(軸)선상으로 일체로 형성되고, 작동관(11)과 환상부재(12) 사이에서 공기공(15)이 형성되도록 다수의 지지변(13)을 유설시키고 그 환상부재(12)의 외방으로 연질의 환상디스크(14)를 유착시켜서 된 가동디스크(10), 관(25)의 내측 상연부(22)와 경사면(28)의 외측상연부(21)가 수평선상에서 고정부재(29)에 의하여 연결되어 수직통기공(23)을 형성하고 한쌍의 수평통기공(24)을 경사면(28)에서부터 관(25)의 내부까지 통공되고 환상 두부(20)의 하측외주연에는 단턱돌부(27)가 돌설되어 있고 관(25)의 하측에는 배수관 삽입요부(26)가 하향지게 형성되어 있으며, 환상두부(20)의 단턱돌부(27)에는 덮개(30)의 내측면 요홈(32)에 삽입 결칙되고 작동관(11)에 의하여 덮개(30)의 안내봉(31)에 삽입된 가동디스크(10)가 배수관(40)의 압에 의하여 상하로 작동하면서 외부의 공기를 관(25)내에 흡입하여 배수관내에 유입시켜 배수관 내부가 부분적으로 진공상태가 되는 것을 방지하기 위한 것이다.1 is an exploded perspective view of the present invention, the guide rod 31 is formed integrally in the axial line in the inner center of the cover 30, the air hole between the operating tube 11 and the annular member 12 The movable disk 10 and the inner upper edge portion of the tube 25 which are formed by leaving a plurality of support sides 13 so as to form 15 and adhering the flexible annular disk 14 to the outside of the annular member 12. 22 and the outer upper edge portion 21 of the inclined surface 28 are connected by the fixing member 29 on the horizontal line to form a vertical vent hole 23, and a pair of horizontal vent holes 24 from the inclined surface 28 It is perforated to the inside of the tube 25, and the stepped protrusion 27 is protruded in the lower outer periphery of the annular head 20, and the drain pipe insertion recess 26 is formed downward in the lower side of the tube 25, and the annular head In the stepped portion 27 of the 20, the movable die inserted into the guide rod 31 of the cover 30 is inserted into the inner groove 32 of the cover 30 and inserted into the groove 30 by the operating pipe 11. While the scrubber 10 operates up and down by the pressure of the drain pipe 40, the outside air is sucked into the pipe 25 and introduced into the drain pipe to prevent the inside of the drain pipe from being partially vacuumed.

본 발명은 제2도에 도시된 바와같이 통상적으로 닫혀져 있는 상태이나, 즉 환상부재(12)와 환상 디스크(14)등의 자체무게에 의하여 가동디스크(10)는 외측 상연부(21)와 내측 상연부(22)위에 안치되어 항상 수직 통기구(23)를 폐쇄하는 상태가 되는 것이다.The present invention is in a normally closed state as shown in FIG. 2, i.e., the movable disk 10 has its own outer edge 21 and the inner side due to its own weight, such as the annular member 12 and the annular disk 14; It is settled on the upper edge part 22, and it will be in the state which always closes the vertical vent 23.

배수관(40)에 연결된 관(25)내의 압력이 공기공(15)을 통하여 가동디스크(10)의 환상디스크(14) 상측면부에 미치게 되며, 그 압력에 의하여 관내가 부분적으로 진공상태가 되고, 일정한 기압(약 50ρ∂ 내외)에 달하면 수직 통기구(23)를 통하여 환상디스크(14)의 하측부에 작용하는 대기압에 의하여 가동디스크(10)가 상승함으로써 폐쇄된 수직통기구(23)는 개방되고 개방된 수직통기구(23)를 통하여 유입되는 대기압(공기)이 관(25) 내부에 인입되어 배수관내의 진공상태를 무마시키게 되며 부분 진공상태가 평정되면 가동디스크(10)는 다시 하향하여 수직 통기구(23)을 폐쇄하게 되는 것이다.The pressure in the pipe 25 connected to the drain pipe 40 reaches the upper surface portion of the annular disk 14 of the movable disk 10 through the air hole 15, and the pressure inside the pipe is partially vacuumed. When a certain air pressure (approximately about 50 p∂) is reached, the movable vertical cylinder 23 is opened by the atmospheric pressure acting on the lower side of the annular disk 14 through the vertical vent 23, and the closed vertical vent 23 is opened and opened. Atmospheric pressure (air) introduced through the vertical vent hole 23 is introduced into the tube 25 to smooth out the vacuum state in the drainage pipe. When the partial vacuum state is stabilized, the movable disk 10 moves downward again to the vertical vent hole 23. ) Will be closed.

즉 배수관(40)에 연결된 가지관(도시하지 아니함)에서 폐수를 방류하게 되면 페수가 유입되는 배수관의 위치에서부터 본 발명이 작동된 배수관에 있는 공기가 하향 배출되는 폐수의 압력에 이끌리어 하향하여 배수관내의 일부를 순간적으로 진공상태로 유지시켜 버리게 되며, 이렇게 배수관내에서 일부가 진공상태가 되면 상술한 바와같은 작용에 의하여 외기(공기)가 배수관내에 유입됨으로서 진공상태를 제거하게 되는 것이다.That is, when the wastewater is discharged from the branch pipe (not shown) connected to the drain pipe 40, the wastewater is discharged downward from the position of the drain pipe into which the waste water flows in. Some of them are kept in a vacuum state instantaneously, and if some of them are vacuumed in the drain pipe, the outside air (air) is introduced into the drain pipe by the above-described action to remove the vacuum state.

한편 배수관내에서 상승 억류하는 압이 발생하였을 경우에는 공기공(15)을 통하여 또한 수평 통기공(24)에 의하여 압력이 가동 디스크(10)의 환상 디스크(14) 상단을 하방으로 압압하게 됨으로서 수직통기구(23)를 폐쇄하고 있는 가동디스크(10)를 더욱 부동의 상태로 함으로서 더욱 견고하게 폐쇄하게 되는 특성이 있는 것이다.On the other hand, in the case where the pressure of rising and detaining in the drain pipe is generated, the pressure is pushed downward through the air hole 15 and by the horizontal vent 24 to press the upper end of the annular disk 14 of the movable disk 10 downward. The movable disk 10 that closes the vent 23 is made to be in a more floating state to have a characteristic of being closed more firmly.

특히 본 발명에서 환상부재(12)에 연질의 환상디스크(14)가 삽착되어 외측 상연부(21)와 내측 상연부(22)위에 가볍게 올려져 있는 상태가 되므로 상호간에 약간 편차가 있다. 할지라도 항상 밀접하게 밀봉되는 상태가 유지되는 것이다.Particularly, in the present invention, the flexible annular disk 14 is inserted into the annular member 12 so that it is lightly placed on the outer upper edge 21 and the inner upper edge 22, so there is a slight deviation from each other. Even if it is always tightly sealed.

뿐만 아니라 본 발명은 구조가 매우 간단하면서도 신뢰도가 높고 가동디스크(10)를 상측 연부에서 의도적으로 작용시키는 것과 같은 착각을 일으킬 정도로 자연스럽게 개폐 작용이 되도록 되어 있는 특성이 있는 것이다.In addition, the present invention is characterized in that the structure is very simple and reliable, and the opening and closing action is so natural that it causes an illusion such as intentionally acting the movable disk 10 at the upper edge thereof.
