Problems solved by technology

[0003] Since the fire hydrant shell is made of cast iron, it is often rusted and stuck when it is fixed for a long time. After it is stuck, it is extremely difficult to open it by hand due to the corner installed in the fire box, which is very inconvenient in an emergency , and it is easy to cause the middle part of the screw to deform and cause water leakage after the tool is knocked off

Embodiment

[0026] Such as Figure 1-Figure 7 As shown, the present invention provides an indoor fire hydrant maintained by rod shaft vibration. It is horizontally fixed on the top of the valve seat 2 and the connection is sealed. The connecting nut 3 is welded and fixed on the bottom of the valve seat 2 and has an integral structure. The outlet pipe 4 is installed on the right side of the valve seat 2 and inside In communication, the nozzle on the right side of the outlet pipe 4 is nested with the quick connector 5, and the internal structure of the rotary valve 1 includes: a runner 11, a central valve stem 12, a lubricating device 13, a valve 14, an anti-seize Head 15, sealing lower cover 16, the runner 11 interlocks with the engaging thread on the top of the central valve stem 12 through the nut in the middle, the valve 14 is installed at the bottom of the lubricating device 13 and the central shaft and the central valve stem 12 connected, the sealing lower cover 16 is tightly attache...

Abstract

The invention discloses an indoor fire hydrant based on rod shaft vibration maintenance. The indoor fire hydrant structurally comprises a rotary valve, a valve seat, a connecting nut, a water outlet pipe and a quick coupling, wherein the bottom of the rotary valve is horizontally fixed at the top end of the valve seat, the connecting part is subjected to sealing treatment, the connecting nut is welded and fixed at the bottom of the valve seat to form an integrated structure, the water outlet pipe is mounted on the right side of the valve seat and communicated with the valve seat from inside, and a pipe orifice in the right side of the water outlet pipe is mutually nested with the quick coupling. In conclusion, after improvement of the fire hydrant, a thread in the rusted position is subjected to high-frequency impact accurately by an internal impact ball head and enabled to be loosened, crowds can be reminded to evacuate by knocking the pipeline, and loss caused by the fact that the fire hydrant cannot be used under the emergency situation is avoided.

Description

technical field [0001] The invention relates to a fire-fighting device, in particular to an indoor fire hydrant maintained by vibration of a rod shaft. Background technique [0002] The indoor fire hydrant is an indoor pipe network that supplies water to the fire scene. It has a valve interface and is an indoor fixed fire-fighting facility for factories, warehouses, high-rise buildings, public buildings, and ships. It is used together, but some problems are prone to occur due to the low frequency of use: [0003] Since the fire hydrant shell is made of cast iron, it is often rusted and stuck when it is fixed for a long time. After it is stuck, it is extremely difficult to open it by hand due to the corner installed in the fire box, which is very inconvenient in an emergency , And it is easy to cause the middle part of the screw to deform and cause water leakage after the tool is knocked off. Contents of the invention [0004] In view of the above problems, the present in...
