Patent number: 9097352Abstract: A relief valve for overload protection includes a switching member disposed at the inlet, and a guide pillar in sealed connection with the switching member. The guide pillar is provided with a first water outlet and a second water outlet disposed in the direction of water flowing, and a slidable sleeve is disposed on an outer side of said guide pillar. When the water pipe connected to the outlet cracks, the water pressure at said outlet may drop, which leads to further movement of said slidable sleeve towards the outlet and cause the plug disposed on the top of said slidable sleeve to plug the outlet in a sealed manner, thus closing the outlet.Type: GrantFiled: June 28, 2012Date of Patent: August 4, 2015Assignee: ZHUHAI BOW KITCHEN & BATH PRODUCTS CO., LTD.Inventors: Xunping Yuan, Zhiqiang Tang
