Spherical rapid hydraulic fire hydrant and working method thereof

Abstract

The invention relates to a spherical rapid hydraulic indoor fire hydrant which comprises a housing provided with a cavity, wherein a movable valve core is arranged in the housing, the cavity in the housing is divided into a first channel and a second channel by the valve core, a water inlet and a water outlet which are communicated, are respectively arranged on the housing, an interface matched and connected with a fire protection water band is arranged at a port of the water outlet, a valve body is further assembled at the upper end of the housing, the valve body comprises a valve cover, a valve rod, a steel ball and a handle, wherein the valve cover and the housing are fixedly mounted, a liquid flow cavity is arranged in the valve cover, the liquid flow cavity is communicated with the first channel and the second channel, a third channel communicated with the liquid flow cavity is further arranged on the valve cover, the front end and the back end of the third channel are respectively connected with a pressure gauge and a sealing and fixing part, the valve rod is further arranged on the valve cover, the handle is fixedly arranged at the upper end of the valve rod, the steel ball is arranged at the lower end of the valve rod, and an inverted L-shaped opening is arranged on the steel ball. The opening way or the closing way of the spherical rapid hydraulic indoor fire hydrant does not need to overcome the liquid pressure manually, and the fire hydrant can be opened or closed by converting the working state of the valve rod with very small force.

Description

technical field [0001] The invention relates to a fire hydrant, in particular to a spherical rapid hydraulic indoor fire hydrant and its working method. Background technique [0002] Present indoor fire-fighting equipment has two kinds, and a kind of is foam fire extinguishing cry, has the shortcoming of small capacity, fire extinguishing distance; When a fire breaks out, it is necessary to temporarily deploy the fire hose belt and put it into use quickly. However, the valves of this indoor fire hydrant are generally adjusted manually. In the process of adjusting the switch, manpower is required to overcome the pressure of the fluid. For large valves, tools such as wrenches are often used to open them. It is difficult to manually open and close the valve. The labor intensity is high, the switch wears out quickly every time, it is inconvenient to use, and it cannot be put into use quickly, which often delays the fire extinguishing time and causes the fire loss to expand.
