Indoor and outdoor hydraulic pressurizing fire hydrant and pressurizing method thereof

Abstract

The invention relates to an indoor and outdoor hydraulic pressurizing fire hydrant and a pressurizing method thereof. A high pressure liquid inlet and outlet valve and is connected to an upper shell through a connecting flange; a plunger cylinder is connected to the high pressure liquid inlet and outlet valve and is fixed in the upper shell; the upper shell is connected to a lower shell at a partition blind plate; an upper piston cylinder, a reversing cylinder and a lower piston cylinder are fixed in the upper and lower shells through fixed plates; a valve power liquid drain outlet is formed in the upper shell; the lower part of the lower shell is connected to a water inlet through a flange; and the water inlet is connected to a civil water pipe. The indoor and outdoor hydraulic pressurizing fire hydrant provided by the invention has the beneficial effects that 1, fire fighting water supply for high-rise buildings can be achieved when fires happen, and the effluent pressure can be increased by means of a pressurizing principle that a large piston drives a small plunger; 2, water is supplied through a civil pipeline network, and the demand of water on fire-fighting is directly met through the pressurizing fire hydrant; and 3, the pressurizing fire hydrant is not controlled by a circuit.

Description

technical field [0001] The invention relates to an indoor and outdoor hydraulic pressurized fire hydrant for fire-fighting, which belongs to the supporting facilities for fire-fighting. Background technique [0002] With the continuous development of our country's infrastructure, there are more and more high-rise buildings in various places. The following 5 problems have emerged in fire protection: 1. In recent years, fires have occurred in high-rise buildings in my country. At present, the water supply height and water supply volume of domestic fire protection systems in my country are seriously insufficient. Taking the fire-fighting needs of high-rise buildings as an example, floors exceeding 80m cannot The realization of high-pressure water supply prevents the fire from being effectively controlled in a timely manner, far from achieving the function of fire fighting and extinguishing. 2. Indoor and outdoor fire hydrants cannot supply water in time. At present, fire-fight...

Problems solved by technology

[0003] The purpose of the present invention is to address the above-mentioned deficiencies in the prior art, to provide an indoor and outdoor hydraulic pressurized fire hydrant driven by water pressure, which can increase the water outlet pressure of the fire hydrant, shorten the water outlet time, and can be directly used for civil water supply pipe networks. Water-driven, high working efficiency, reasonable structural layout, easy processing, manufacturing and assembly, can use the existing fire protection pipes for transformation, low implementation difficulty, low transformation cost; to solve the problem that the existing fire hydrants have slow water outlet speed and the water outlet pressure cannot meet the requirements. It cannot work when the power is off, and it is a technical problem with high requirements for fire protection circuits
