During this time, the valve plate seal 43 undergoes a brief period of time from just contact with the plug opening 2 to the creation of an elastically compressed seal with the plug opening 2. In this process, the valve plate assembly 4 is mounted on the control rod 3 in a sealing and rotating manner, so that the valve plate assembly 4 can be prevented from rotating with the control rod 3 in a hard manner, that is, the operation resistance to the opening and closing operation part 6 caused by the hard rotation between the valve plate assembly 4 and the bolt opening 2 is avoided, and therefore, the tight blocking can be realized only by operating the opening and closing operation part 6 to enable the control rod 3 to rotate in the opposite direction continuously, and the blocking operation is simple and labor-saving. Finally, the valve plate assembly 4 maintains a reliable sealing action under the elastic sealing of the valve plate sealing ring 43 and the axial limitation of the thread guiding structure 5. Therefore, the purpose of reducing the use of the bolt mouth 2 under the condition of not stopping water is achieved, and the influence of water stopping on water use work, particularly fire extinguishing work, is avoided.
When all the bolt ports 2 are used, the bolt ports 2 are blocked according to the operation of reducing the use of the bolt ports 2, and the bolt cover 21 is covered again.
In this embodiment, the bolt ports 2 are arranged up and down, and are respectively controlled to be opened and closed by a set of control rod 3, a valve plate assembly 4, an opening and closing operation part 6, a thread guiding structure 5 and the like, so that the opening and closing of the bolt ports 2 are not affected, and the opening and closing operation is also convenient. Meanwhile, the embodiment omits the use of the total valve plate at the bottom of the bolt body 1, and the combination of the set of control rod 3, the valve plate assembly 4, the thread guiding structure 5 and the opening and closing operation part 6 used by each bolt opening 2 has simple structure, so that the whole fire hydrant does not show obvious cost increase, and the cost is low.
