Abstract

The utility model discloses a check trap which comprises an upper portion check trap, a lower portion check trap and a plastic check ball. The upper portion check trap comprises a round stainless steel sheet, a narrow water drainage pipeline and a conduit. A round hole is arranged adjacent to the center of the stainless steel sheet. The narrow water drainage stainless steel pipeline is welded below the round hole. The other side of the round hole of the stainless steel sheet is welded with the stainless steel conduit. The lower portion check trap is a semi-round-shaped curved pipeline. Two ends of the semi-round-shaped curved pipeline are thick. The lower end of the narrow water drainage pipeline is inserted into one end of the lower portion check trap and sealed in welded mode. The other end of the lower portion check trap is horn-mouth-shaped and arranged straightly under the conduit. The plastic check ball is clamped in the horn-mouth-shaped end of the lower portion check trap. The check trap is reasonable and simple in structure, convenient to manufacture, and safe and reliable in use and effectively solving the problem that under the condition that sanitary equipment is not used for a long time or water drainage is low, water seal is dried and radon gas can easily spread into a room.

Description

The non-return trap

Technical field

The utility model belongs to a kind of trap, especially relates to a kind of non-return trap.

Background technology

Research finds that esidential building has 1/3 room to measure radioactive radon, this is to be fissioned and a kind of gas of generation by radioactive element uranium and radium, have strong carcinogenesis, research report shows, indoor indoor radgas---radon nearly has that half enters indoor from sewer.Although trap or the water seal of various shapes being housed mostly at place, the lower mouth of a river, if sanitary installation many days need not (as the bathtub in winter) or displacement when less, water seal dry state often, radon gas just wafts into indoor.

Summary of the invention

The purpose of this utility model will overcome the above problems exactly, a kind of non-return trap is proposed, simple and reasonable, easy to make, safe and reliable, can effectively solve sanitary installation because of many days need not or displacement when less, water seal often is in dry state, causes radon gas easily to waft into indoor problem.

The purpose of this utility model is achieved like this: a kind of non-return trap is characterized in: it comprises part non-return trap 1, lower part non-return trap 2, plastics non-return spin 3; Upper part non-return trap 1 comprises circular Thin Stainless Steel steel plate 7, thin sewer pipe 4, conduit 8, partial center position at Thin Stainless Steel steel plate 7 has circular hole, the thin sewer pipe 4 of the stainless steel identical with Circularhole diameter is welded on circular hole below, is welded with stainless steel pipe 8 than thick No. two of thin sewer pipe 4 at the opposite side of Thin Stainless Steel steel plate 7 circular holes; Lower part non-return trap 2 is semi arch crooked pipeline shape, two of semi arch crooked pipeline is thicker, one and welded seal of lower part non-return trap 2 inserted in the lower end of thin sewer pipe 4, the other end of lower part non-return trap 2 is bell mouth shape, be positioned at conduit 8 under, leave certain gap between the horn mouth of lower part non-return trap 2 and the bottom of conduit 8, plastics non-return spin 3 is installed in horn mouth.

The utility model is not only simple and reasonable, easy to make, safe and reliable, effectively solved because of sanitary installation many days need not or displacement when less, water seal is dry state often, radon gas easily wafts into indoor problem.

Description of drawings

Fig. 1 is the use view of utility model.

In figure: 1, upper part non-return trap; 2, lower part non-return trap; 3, non-return spin; 4, thin sewer pipe; 5, lower mouth of a river cover plate; 6, ground; 7, Thin Stainless Steel steel plate; 8, conduit; 9, thick sewer pipe.

The specific embodiment

As can be seen from Figure 1: the utility model is comprised of upper part non-return trap 1, lower part non-return trap 2, non-return spin 3.Upper part non-return trap 1 is to open a hole by a circular Thin Stainless Steel steel plate 7 in the partial center position, with stainless steel sewer pipe 4 welding of hole size coupling, at the opposite side welding in the circular Thin Stainless Steel steel plate 7 holes stainless steel pipe 8 than large No. two of stainless steel sewer pipe 4; Lower part non-return trap 2 is crooked pipelines, the bottom of the sewer pipe 4 of part non-return trap 1 in insertion, and firm welding, the other end is horn mouth, put into plastics non-return spin 3, align with plastics non-return spin 3 conduits 8, stay the 10mm gap.Comprise part non-return trap 1, lower part non-return trap 2, plastics non-return spin 3; Upper part non-return trap 1 comprises circular Thin Stainless Steel steel plate 7, thin sewer pipe 4, conduit 8, partial center position at Thin Stainless Steel steel plate 7 has circular hole, the thin sewer pipe 4 of the stainless steel identical with Circularhole diameter is welded on circular hole below, is welded with stainless steel pipe 8 than large No. two of thin sewer pipe 4 at the opposite side of Thin Stainless Steel steel plate 7 circular holes; Lower part non-return trap 2 is semi arch crooked pipeline shape, two of semi arch crooked pipeline is thicker, one and welded seal of lower part non-return trap 2 inserted in the lower end of thin sewer pipe 4, the other end of lower part non-return trap 2 is bell mouth shape, be positioned at conduit 8 under, stay certain gap, the gap can be 10mm, and plastics non-return spin 3 is installed in horn mouth.

During use, with the non-return trap, be placed in the thick sewer pipe 9 under ground 6, then cover lower mouth of a river cover plate 5.When discharging water, plastics non-return spin 3 is flushed in conduit 8 by water, water flows into thick sewer pipe 9 from the gap location between horn mouth and conduit 8 and discharges, after drained water, plastics non-return spin 3 falls back to blocks lower part non-return trap 2 in horn mouth, guaranteed that the gas in thick sewer pipe 9 can not flow into indoor from thin sewer pipe 4.
