NONFREEZING WATER DRAINING PIPE FOR PREVENT WINTER SOWING

摘要

The subject innovation relates to a floating water note intake structure for freeze protection, by forming the possible intake structure, the inflow of air to the water supply main phase of the water supply states regardless of the type of tap provided in the water supply note tip is retained it can rapidly discharged It would be to allow.; For realizing this, to floating water of the subject innovation, the underground constant pipe 8 and the water supply main (2) connection part has been installed, a floating valve housing 1, the water supply main (2) The tip of faucet 3 have been connected to mounting, in said floating valve housing 1 has a valve body 14 by the vertical movement been installed valve stem 12 is rotatably nahap for opening and closing the flow passage, the valve stem 12 is rotated in for floating the floating water supply main valve key 5 has been installed in the key protective pipe 6, an intake hole at the upper end connection part between the water supply main (2) and the faucet (3) to enable the air flowing from the outside ( 10a) is a tea intake port 10 is formed and been mounted; In the intake port tee (10) is characterized in that the float valve 11 for opening and closing the intake hole (10a) by the vertical movement is provided with the insert.
