Floating ball type anti-reverse-gushing water valve of sewer pipe
The invention relates to the technical field of valves, in particular to a sewer pipe floating ball type reverse gushing prevention water valve which comprises a valve body, a valve cavity is formed in the valve body, a floating ball is arranged in the valve cavity, a large-aperture filter plate capable of lifting and bearing the floating ball is arranged in the valve body, and the floating ball can obtain upward buoyancy to automatically block the valve cavity during water reverse gushing; according to the sewer pipe floating ball type reverse gushing prevention water valve, the valve cavity can be blocked when water reversely gushes through the floating ball arranged in the valve cavity, and the floating ball can be matched with the lifting and bearing functions of the large-aperture filter plate, so that the floating ball can be prevented from blocking the valve body when water is drained, and the valve cavity can be automatically blocked only by obtaining the reverse gushing prevention floating capacity; an elastic bulge is arranged in the valve cavity, so that the clogging leakproofness of the floating ball during reverse surging can be further improved; the valve is reliable in structure, easy and convenient to install and capable of being suitable for water gushing prevention of an existing sewer pipe, and the normal drainage capacity of the sewer pipe cannot be affected.
本发明涉及阀门技术领域，具体为下水管浮球式防反涌水阀门，包括阀体，所述阀体内部设有阀腔，所述阀腔内设有浮球，且所述阀体内设有能够托举承载所述浮球的大孔径滤板，所述浮球在水反涌时能够获得向上的浮力自动堵塞所述阀腔；该下水管浮球式防反涌水阀门，通过在阀腔内设置的浮球能够在水反涌时堵塞阀腔，并且浮球配合大孔径滤板的托举承载功能，能够避免浮球在排水时堵塞阀体，使其仅获得防反涌的上浮能力自动堵塞阀腔；并且阀腔内设有的弹性凸起能够进一步提高浮球在反涌时堵塞的密闭性；该阀门结构可靠，安装简便，能够适用于现有下水管路防水涌用，且不会影响下水管正常排水能力。
