Anti-freeze valve with drain valve that can prevent damage and leakage
The present invention relates to an anti-freeze valve with a drain valve capable of preventing damage and leakage and to an anti-freeze valve with a drain valve capable of preventing damage and leakage, which, in order to prevent damage to an O-ring, occurring according to up/down operations of a lifting/lowering body coupled to the O-ring due to an elastic member in a process of locking and unlocking a drain valve in accordance with the operation of a lever of an anti-freeze valve, prevent a phenomenon in which the O-ring is rolled by being pushed on the inner circumferential surface of a drain valve body or prevent a leakage phenomenon by lowering of watertightness due to a friction in a prior art, is configured to: replace the lifting/lowering body with an elastic sheet block; allow a wedge surface of the elastic sheet block to seal a drain hole by elastic deformation; be formed such that a water supply control valve presses the elastic sheet block to open the drain hole by expansion of the lower part of the elastic sheet block and reduction in pressing the upper part thereof and thus to determine opening and closing of the drain hole; smoothly prevent freezing and bursting in the winter by discharging remaining water through the drain hole opened through the locking process of the drain valve; and increase a service life.
본 발명은 파손 및 누수방지가 가능한 퇴수밸브를 가진 부동전에 관한 것으로, 종래 부동전의 레버의 작동에 따라 퇴수밸브를 잠그고 푸는 과정에서 오링이 결합된 승강체가 탄성부재에 의해 상하 작동됨에 따라 발생되는 오링 파손이나 오링이 퇴수밸브체 내주연 면에 밀려 말림되는 현상 내지는 마찰로 인한 수밀력 저하로 누수 현상이 발생되지 않도록 승강체를 탄성시트블럭으로 대체하고, 탄성시트블럭의 웨지면이 탄성변형에 의해 퇴수공을 밀폐시키고, 급수단속밸브가 탄성시트블럭을 가압하여 탄성시트블럭의 하부팽창과 함께 상부 가압축소로 퇴수공이 개방되도록 형성되어 퇴수공의 개폐가 결정되고, 퇴수밸브의 잠금과정을 통해 개방되는 퇴수공을 통해 잔류수가 퇴수공으로 배출되어 동절기 동파방지가 원할하게 이루어지며, 사용수명증대가 가능한 파손 및 누수방지가 가능한 퇴수밸브를 가진 부동전에 관한 것이다.
