一种自来水用安全阀
摘要：
本发明公开了一种自来水用安全阀，在其阀体(1)的下端设有进水口(3)和出水口(4)，在阀体(1)中装有滑阀(5)和阀体内套(6)；在阀体(1)上部装有提升机构(7)和紧定套筒(8)，在紧定套筒(8)上设有凹槽(9)；在提升机构(7)上装有导向杆(10)和推力弹簧(11)；在阀体(1)与阀体内套(6)、阀体(1)与滑阀(5)以及滑阀(5)与阀体内套(6)之间装有密封圈(13)；在阀体内套(6)上设有导流槽(14)，在导流槽(14)上装有膨胀型密封圈(15)。本发明能够在停水以及恢复供水时自动保持关闭状态，防止自来水用户在忘记关水龙头时造成自来水的流失及导致的水资源浪费和经济损失。
摘要（英）：

The invention discloses a safety valve for tap water. The lower end of a valve body (1) is provided with a water inlet (3) and a water outlet (4). A sliding valve (5) and a valve inner sleeve (6) are arranged in the valve body (1). The upper portion of the valve body (1) is provided with a lifting mechanism (7) and a fastening sleeve (8), and a groove (9) is formed in the fastening sleeve (8). The lifting mechanism (7) is provided with a guide rod (10) and a thrust spring (11). Sealing rings (13) are arranged between the valve body (1) and the valve inner sleeve (6), between the valve body (1) and the sliding valve (5) and between the sliding valve (5) and the valve inner sleeve (6). The valve inner sleeve (6) is provided with a flow guide groove (14), and an expansion type sealing ring (15) is disposed on the flow guide groove (14). According to the safety valve, the safety valve can automatically keep in a closed state when water stops or continues to be supplied, and water resource waste and economic loss caused due to the fact that a tap water user forgets to turn off a faucet and the tap water flows are prevented.
