Title (EN) WATER PIPING SYSTEM HAVING WATER HAMMER BUFFERING FUNCTION USING EJECTOR EFFECT AND PRESSURE TANK CONNECTOR THEREFOR
(FR) SYSTÈME DE CANALISATION D'EAU AYANT UNE FONCTION D'AMORTISSEMENT DE COUP DE BÉLIER UTILISANT UN EFFET D’ÉJECTEUR ET RACCORD DE RÉSERVOIR DE PRESSION ASSOCIÉ
(KO) 이젝터 효과를 이용한 수충격 완화 기능을 구비하는 수배관 시스템 및 이를 위한 압력탱크 연결구
Abstract:
(EN) The present invention relates to a water piping system and, more particularly, to a water piping system and a pressure tank connector therefor, the water piping system being configured such that, when a pump of water piping stops abruptly, water stored in a pressure tank is ejected at a high pressure in the main flow direction of piping water inside main piping, thereby delaying the reverse flow of the piping water, and pressure applied to a check valve is reduced, thereby inducing a slow closure of the check valve, and buffering the slam and water hammer applied to the check valve.
(FR) La présente invention concerne un système de canalisation d'eau et, plus particulièrement, un système de canalisation d'eau et un raccord de réservoir de pression pour ce dernier, le système de canalisation d'eau étant configuré de telle sorte que, lorsqu'une pompe de canalisation d'eau s'arrête soudainement, l'eau stockée dans un réservoir de pression est éjectée à une pression élevée dans la direction d'écoulement principale d'eau de canalisation à l'intérieur d'une canalisation principale, retardant ainsi l'écoulement inversé de l'eau de canalisation, et une pression appliquée sur un clapet anti-retour est réduite, ce qui permet d'induire une fermeture lente du clapet anti-retour et d'amortir le claquement et le coup de bélier appliqués au clapet anti-retour.
(KO) 본 발명은 수배관 시스템에 관한 것으로, 보다 상세하게는, 수배관의 펌프 급정지시 압력탱크에 저장된 물을 주배관의 배관수 주 흐름 방향으로 고압 분출시킴으로써 배관수의 역류를 지연시키고 체크밸브에 가해지는 압력을 감소시킴으로써 체크밸브의 완폐를 유도하여 체크밸브의 슬램 및 수충격을 완화할 수 있는 수배관 시스템 및 이를 위한 압력탱크 연결구에 관한 것이다.
