Abstract
The invention discloses a backflow-prevention joint, which comprises a joint main body; a waterway is arranged in the joint main body; the joint main body consists of a hexagon nut and a pipeline; the waterway penetrates the hexagon nut and the pipeline; the hexagon nut is provided with a backflow-prevention device; the backflow-prevention device comprises a through hole, a backflow-prevention valve core and an elastic spring, wherein the through hole is formed in the side part of the hexagon nut, the backflow-prevention valve core is arranged in the through hole, and the elastic spring is used for fixing the backflow-prevention valve core in the through hole. The backflow-prevention joint disclosed by the invention simple in structure, and is capable of preventing remained water in water outlet devices, such as a shower, from flowing back to a water supply source and a drinking water pipeline from being polluted.
Description
Technical field
The present invention relates to sanitary bath equipment field, particularly relate to a kind of anti-return joint preventing the remaining water in water outlet device to be back to water source and polluted source.
Background technique
At present, at use water outlet device if gondola water faucet is after shower terminates, Yu Shui can be left in its inside, if emptying not in time, there is rotten or breed bacteria in the Yu Shuihui after a period of time in gondola water faucet, when supply channel produces negative pressure condition, Yu Shuihui in gondola water faucet flows backward in watering, rotten water may flow in drinking water pipeline, causes potable water contaminated, therefore can there is unhygienic, unsound hidden danger.
Summary of the invention
The present invention in order to solve the above problems, provide a kind of prevent the remaining water in water outlet device to be back to drinking water pipeline and polluted source to reach the anti-return joint of water supply security health.
The technical solution adopted for the present invention to solve the technical problems is: a kind of anti-return joint, comprise adapter body, water channel is provided with in adapter body, adapter body is made up of hexagon nut and a pipeline, the through hexagon nut of water channel and water channel, described hexagon nut is provided with back-flow preventer, described back-flow preventer comprise the through hole being located at hexagon nut sidepiece, the anti-backflow spool be located in through hole, for anti-backflow spool being fixed on the elastic spring in through hole.
Further, described anti-backflow spool is stop valve.
Further, described stop valve is provided with cavity; Stop valve one end is outwardly enclosed construction, and the one end towards passage is provided with 6 spoke type end caps.
The invention has the beneficial effects as follows: a joint is set before the water intake of water outlet device, joint is provided with back-flow preventer; When current are from the feed-water end waterexit end that inflow internal diameter is larger at a high speed that internal diameter is less, water flow jet makes to form negative pressure in the cavity of anti-backflow spool, when after closedown watering, remaining water in water outlet device because of the pressure of anti-reflux valve in-core less and flow into anti-reflux valve in-core, the remaining water in the water outlet devices such as gondola water faucet can be prevented to be back to watering, the ducted water of polluted drinking water.
