Fire hydrant and method for preventing leakage during damage
The invention provides a fire hydrant and a method for preventing leakage during damage, relates to the field of fire hydrants, and aims to solve the problem that a valve structure of an existing anti-collision fire hydrant is prone to being damaged to cause plugging failure, a butterfly plate is matched with a valve seat to form a leakage-proof structure located in a valve body, and the butterfly plate of a normally-closed structure is in an open state under the action of a limiting piece; the opening degree can meet the requirement for high-flow water supply of the fire hydrant, the independent limiting piece is adopted, after the hydrant body is damaged, the limiting piece can be separated from the original position, so that the butterfly plate is closed to complete blocking of a water path, the leakage-proof structure is prevented from extending to the outside to be affected, and the sealing requirement after the hydrant body is damaged is met.
本发明提供一种损坏防泄漏消火栓及方法，涉及消火栓领域，针对目前防撞消火栓的阀结构容易受到损伤而导致封堵失效的问题，采用蝶板配合阀座形成位于阀体内的防泄漏结构，常闭结构的蝶板在限位件作用下处于开启状态，开度能够满足消火栓大流量供水的需求，采用独立的限位件，在栓体损坏后限位件能够从原位置脱离使蝶板关闭完成对水路的封堵，避免防泄漏结构延伸至外部而受到影响，满足栓体损坏后的密封需求。
