The invention provides a multifunctional self-closing valve, and relates to the field of valve bodies, the multifunctional self-closing valve comprises a valve body mechanism and a floating ball mechanism, the valve body mechanism comprises a valve body, the middle part of the valve body is provided with a hollow cavity which is through up and down, and the floating ball mechanism is of a hollow sphere-like structure; the valve body is vertically fixed in the cooling water tank through the flange connecting part, the upper end of the self-closing valve is externally connected with the cooling water pipeline, cooling water flows into the cooling water tank along the cooling water pipeline and the self-closing valve under the normal working condition, and the floating ball mechanism floats up and down along the floating ball cavity along with the change of the liquid level under the marine bumpy working condition; when the upper portion of the floating ball mechanism abuts against the first sealing ring, the floating ball mechanism seals the shrinkage cavity, liquid is limited to flow from bottom to top, and then cooling water smoothly flows back to the cooling water tank under normal pressure. Opening and closing of the self-closing valve completely depend on buoyancy, so that the self-closing valve can better adapt to the complex working environment on the sea and is high in practicability, better in durability and high in market value.
本发明提供了一种多功能自闭阀门,涉及阀体领域,包括阀体机构和浮球机构,其中阀体机构包括阀体本体,而阀体本体的中部设有上下贯通的中空腔体,浮球机构是中空的类球形结构,本发明的阀体本体通过法兰连接部竖向固定在冷却水箱内,自闭阀的上端外接冷却水管路,正常工况下,冷却水沿冷却水管路和自闭阀流入冷却水箱内,当在海上颠簸工况下,浮球机构随液体水位变化沿浮球腔上下浮动,当浮球机构的上部抵住第一密封圈时,浮球机构封闭缩口腔体,限制液体从下向上流动,进而实现冷却水常压下顺利回流至冷却水箱;本发明的自闭阀启闭完全依赖浮力,因此能够更加适应海上复杂的工作环境,不仅实用性强,且耐久性更好,市场价值大。
