Embodiment Construction

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.

[0018] refer to figure 1 , an indoor fire hydrant, including a valve body 1, the side wall of the valve body 1 is respectively provided with a first through hole, a second through hole and a third through hole, the axes of the first through hole and the second through hole are collinear, and the first through hole The inner wall of the through hole is threadedly connected with a valve cover 8, and the valve cover 8 is threadedly inserted with a valve stem 9, and the end of the valve stem 9 located outside the valve body 1 is detachably connected with a hand wheel 10, and the valve stem 9 is located inside the valve body 1. One end is detachably connected to the valve...

Abstract

The invention discloses an indoor fire hydrant, comprising a valve body. The side walls of the valve body are respectively provided with a first through hole, a second through hole and a third throughhole, and the axes of the first through hole and the second through hole are collinear. The indoor fire hydrant of the invention is simple in structure. A valve flap abuts against a valve seat; the valve body is closed and is then snapped with a water outlet pipe; a fourth straight rod on the water outlet pipe abuts against a fifth straight rod; the fifth straight rod drives a trapezoidal slide block to move leftward; under the resilience of a third spring, a third straight rod moves, along the slope of the trapezoidal slide block, upward relative to the trapezoidal slide block, and the thirdstraight rod is separated from a first straight rod; and at the time, a hand wheel can be freely rotated to separate the valve flap and the valve seat so as to realize water outflowing. When the water outlet pipe is pulled out, the fourth straight rod is separated from the fifth straight rod; under the resilience of a first spring, the fifth straight rod drives the trapezoidal slide block to moveto rightward, and the slope of the trapezoidal slide block presses the third straight rod; the third straight rod is in clamp connection with the first straight rod again so as to fix the valve flap;so the wasting of water resources caused by accidental contact with the hand wheel is prevented.

Description

technical field [0001] The invention relates to the technical field of fire hydrants, in particular to indoor fire hydrants. Background technique [0002] Fire hydrant, officially called fire hydrant, is a fixed fire-fighting facility whose main function is to control combustibles, isolate combustion-supporting materials, and eliminate ignition sources. There are indoor fire hydrants and outdoor fire hydrants. The fire protection system includes outdoor fire hydrant system, indoor fire hydrant system, fire extinguisher system, and some automatic sprinkler systems, water cannon systems, gas fire extinguishing systems, fire detection systems, water mist systems, etc. Fire hydrants are mainly used for fire trucks to take water from municipal water supply pipe network or outdoor fire water supply pipe network to put out fires, and can also be directly connected to hoses and water guns to extinguish fires; existing fire hydrants do not have self-locking function, and are easy to...
