Definitions

  • an apparatus for preventing a reverse flow of sewage comprising: a connection pipe for allowing the sewage to be introduced into the apparatus therethrough; an upper cover including a through hole comiected to the comiection pipe; a main body, formed in a cylindrical shape, located under the upper cover, and provided with an outlet formed through a lower area of a side surface of the main body, and one pentahedral structure and two hexahedral structures, which protrude from an inner circumference of the cylindrical main body and are sequentially arranged; and a reverse flow prevention sphere, located in the cylindrical main body, serving to open and close the through hole of the upper cover.
  • the upper cover 40 is connected to the main body 70 in a cylindrical shape, which is located under the upper cover 40.
  • a rubber band 50 is interposed between the upper cover 40 and the cylindrical main body 70, and serves as a waterproofing member.
  • the upper cover 40 is screwed to the rubber band 50 so that components, which are out of order, are easily repaired.
  • the through hole 41 is formed in the central area of the upper cover 40.
  • Fig. 3 is an enlarged view of the through hole 41 formed in the central area of the upper cover 40, and shows in detail a portion of the through hole 41, which contacts the reverse flow prevention sphere 60.
  • the present invention provides an apparatus for preventing a reverse flow of sewage, which comprises one pentahedral structure and two hexahedral structures, installed in a cylindrical main body, thus causing a reverse flow prevention sphere to precisely contact a through hole of an upper cover when the sewage flows backward, and allowing the reverse flow prevention sphere to rub with the one pentahedral structure and two hexahedral structures so that foreign substances stuck to the surface of the reverse flow prevention sphere are completely removed. Accordingly, since a gap between the reverse flow prevention sphere and a packing installed in the through hole is eliminated, the apparatus of the present invention efficiently prevents the sewage from flowing backward.
