Ground fire hydrant

Abstract

The invention discloses an overground hydrant which leaks less water after colliding, is more convenient to repair and has lower repairing cost. The overground hydrant comprises a hydrant body, an anti-collision section, a valve body, a water pressure gauge, a floating ball valve and a tappet, wherein an exhausting valve is arranged at the top of the hydrant body; the anti-collision section is arranged between the hydrant body and the valve body; an annular broken groove is formed in an outer side wall of the anti-collision section; a water leakage valve is arranged at a side part of the top of the valve body; the water leakage valve is communicated with an inner cavity of the anti-collision section through a water leakage channel; the water leakage channel comprises an upper-section water leakage channel located in a bottom flange disc of the anti-collision section and a lower-section water leakage channel located in a top flange disc of the valve body; the water pressure gauge is arranged on a side wall of the hydrant body; the water pressure gauge is communicated with the inner cavity of the valve body through a water pressure channel; the water pressure channel comprises an upper-section water pressure channel located in the side wall of the hydrant body and a lower-section water pressure channel located in the side wall of the anti-collision section; the floating ball valve is arranged in the valve body; and the bottom of the tappet stretches to the upper side of the floating ball valve.

Description

technical field [0001] The invention relates to a fire fighting device, in particular to an above-ground fire hydrant. Background technique [0002] Fire hydrants are also called fire hydrants. There are fire hydrants on the ground and fire hydrants on the wall. They are used to supply water to fire trucks or connect water pipes to put out fires. The traditional above-ground fire hydrant includes a plug body and a valve body. The plug body is connected to the valve body, and the valve body is connected to the underground waterway. water supply, while the plug body supplies water from the water supply port on the side. [0003] However, the ground fire hydrant is usually installed beside the road. When it is hit and broken by a vehicle, the valve body will be damaged, which will easily cause a large amount of water leakage, and it is inconvenient to disassemble and replace the valve body, making maintenance difficult. In addition, even if the water pressure gauge on the valv...

[0003] However, the ground fire hydrant is usually installed beside the road. When it is hit and broken by a vehicle, the valve body will be damaged, which will easily cause a large amount of water leakage, and it is inconvenient to disassemble and replace the valve body, making maintenance difficult. In addition, even if the water pressure gauge on the valve body is not damaged They are also replaced together, resulting in waste of resources and high maintenance costs
