Description

Technical Field

[0001] The invention belongs to the technical field of fire hydrant equipment, and in particular relates to a special fire hydrant cover for a fire hydrant valve. Background Art

[0002] In order to strengthen the management of fire hydrants in urban enterprises and residential areas, ground-type fire hydrant covers are installed to prevent units and individuals from using fire water at will, and to effectively manage the opening of fire hydrants, thereby saving water. Once there is a fire and fire water is needed, the fire management personnel or firefighters use a special wrench to open the fire hydrant valve to ensure that the fire hydrant has enough water for fire fighting.

[0003] At present, most fire hydrants are not equipped with water meters, and are often opened at will by users, and fire water is used for greening, infrastructure, sanitation production, etc. There are tens of thousands of fire hydrants in a medium-sized city, which is impossible for the urban water supply company to supervise. In addition to pipeline leakage, bubbling, leaking, and dripping, the fire water loss of urban water supply companies over the years is not a small number. Therefore, in order to eliminate this problem that has not been solved for many years, the Changsha Housing and Urban-Rural Development Bureau has specially issued (2020) 34 document: Notice on Strengthening the Management of Fire Hydrants in Urban Residential Areas of Our City. Therefore, a special fire hydrant cover for fire hydrant valves that cannot be opened at will is urgently needed. Summary of the invention

[0004] The purpose of the present invention is to provide a special fire hydrant cover for fire hydrant valves to solve the problems raised in the above background technology. The present invention provides a special fire hydrant cover for fire hydrant valves that cannot be opened at will. The fire hydrant cover seals the top of the five-sided screw rod of the fire hydrant valve, so that the special wrench cannot open it, so that the fire hydrant cannot be opened at will. After each fire-fighting water is used up, a new fire hydrant cover is reinstalled by a special person from the water supply company to ensure that the fire hydrant cannot be opened at will.
