Extrusion type indoor fire hydrant

Abstract

The invention relates to a fire fighting device, and discloses an extrusion type indoor fire hydrant. The extrusion type indoor fire hydrant comprises a hydrant body with an inner cavity, and the outer wall of the hydrant body is connected with a base and a connecting base. A valve clack capable of opening and closing an input channel is hinged to a port of the end, close to the inner cavity of the hydrant body, of the input channel. The outer wall of the hydrant body is further connected with a sleeve, and the sleeve and the base are arranged on the two opposite sides of the hydrant body correspondingly. The end, located outside the hydrant body, of the sleeve is in threaded connection with an adjusting bolt. The adjusting bolt stretches into the sleeve, and the front end of the adjustingbolt is provided with a first extrusion plate, an adjusting spring and a second extrusion plate, all of which are sequentially connected. The front portion of the adjusting bolt is provided with a rotation clamping block, and the rotation clamping block is clamped in a containing groove of the first extrusion plate. The face, away from the adjusting spring, of the second extrusion plate is connected with a transmission rod, and the two ends of the transmission rod are hinged to the second extrusion plate and the valve clack correspondingly. The extrusion type indoor fire hydrant achieves thepurposes that before an ignition source is extinguished, the input channel can be rapidly connected, water outflow can be rapidly stopped after the ignition source is extinguished, inner abrasion of the fire hydrant is reduced, and the service life is prolonged.

Description

technical field [0001] The invention relates to a fire-fighting facility, in particular to an extrusion type indoor fire hydrant. Background technique [0002] Fire hydrants, officially called fire hydrants, are mainly used to control combustibles, isolate combustion aids, and eliminate ignition sources. The indoor fire hydrant is an important part of the fire water system, and it is installed in the indoor fire box. [0003] When the traditional fire hydrant opens the water valve switch of the fire hydrant, because the valve core is subjected to the upward force of water pressure, it takes a lot of force to open, exposing the water inlet for fire protection, so it cannot be quickly connected to the indoor pipe network. The water source provided by the fire site also needs to overcome the large water pressure when the valve core is closed, and the speed is slow, and it is easy to cause friction between the valve disc and the valve body, which affects the life of the valve d...

AI Technical Summary

Problems solved by technology

[0004] Based on the above problems, the present invention provides a squeeze-type indoor fire hydrant, in order to solve the problem of quickly connecting the input channel before eliminating the fire source and quickly blocking the water outlet after eliminating the fire source, reducing the internal wear of the fire hydrant, increasing the Service life and other issues
