Title (EN) FREEZE PROTECTION VALVE USING A PHASE CHANGE MATERIAL
(FR) SOUPAPE DE PROTECTION CONTRE LE GEL UTILISANT UN MATÉRIAU À CHANGEMENT DE PHASE
(KO) 상변화물질을 이용한 동파 방지 밸브
Abstract: front page image
(EN)The present invention relates to a freeze protection valve which prevents a pipe from freezing by discharging water in the pipe in advance before the pipe is frozen as exterior temperature drops below the freezing temperature of the water. The freeze protection valve comprises: a housing to be coupled to a pipe port of a movable pipe in which a fluid flows; a drain chamber which is provided in a portion of the housing facing toward the pipe port and which has a water intake hole connected to the inside of the movable pipe and a water drain hole connected to the outside of the housing; a receiving chamber which is provided on the opposite side of the drain chamber of the housing and which accommodates a phase change material that is phase-changed from a liquid to a solid according to a temperature drop and reduced in volume; and a plunger which is movably installed in the drain chamber and has: a piston positioned inside the receiving chamber and moved according to the volume variation of the phase change material at one side of the plunger; and a valve for opening/shutting the water intake hole according to the movement of the piston at the other side of the plunger.
(FR)L'invention concerne une soupape de protection contre le gel empêchant un tuyau de geler en évacuant l'eau dans le tuyau à l'avance avant que le tuyau ne gèle quand la température extérieure baisse en dessous de la température de gel de l'eau. La soupape de protection contre le gel comprend : un logement devant être couplé à un orifice de tuyau d'un tuyau mobile dans lequel un fluide s'écoule ; une chambre d'évacuation disposée dans une partie du logement orientée vers l'orifice de tuyau et comportant un trou d'entrée d'eau raccordé à l'intérieur du tuyau mobile et un trou d'évacuation d'eau raccordé à l'extérieur du logement ; une chambre de réception disposée sur le côté opposé de la chambre d'évacuation du logement et accueillant un matériau à changement de phase qui change de phase et devient liquide ou solide en fonction d'une baisse de température et qui réduit de volume ; et un piston plongeur installé de façon mobile dans la chambre d'évacuation et comprenant : un piston positionné à l'intérieur de la chambre de réception et déplacé selon la variation de volume du matériau à changement de phase sur un côté du piston plongeur ; et une soupape pour ouvrir/fermer le trou d'entrée d'eau selon le mouvement du piston de l'autre côté du piston plongeur.
(KO)본 발명은 외기의 온도가 물의 결빙온도 이하로 하강되어 동파 발생의 위험이 발생하기 전에 미리 배관 내의 물을 배출하여 동파 사고를 사전에 방지할 수 있도는 동파 방지 밸브에 관한 것으로, 유체가 흐르는 유동배관의 배관포트에 결합되는 하우징; 상기 하우징의 상기 배관포트를 향하는 부분에 구비되며, 상기 유동배관 내부로 연통된 입수공 및 상기 하우징 외부로 연통된 배수공이 구비된 배수실; 상기 하우징의 배수실 반대측 부분에 구비되며, 기온 강하에 따라 액체에서 고체로 상변화되면서 체적이 감소하는 상변화물질이 수용되는 수용실; 및 상기 배수실에 이동 가능하게 설치되며, 일측에는 상기 수용실 내부에 위치되어 상변화물질의 체적 변화에 따라 이동되는 피스톤이 구비되고, 타측에는 상기 피스톤의 이동에 따라 상기 입수공을 개폐시키는 밸브가 구비된 플런저를 포함하여 구성된다.
