Overview
In building fire water supply systems, air pressure water tanks are usually used instead of high water tanks to meet
the initial water consumption for minute fire protection, but often The use of ordinary pressure water tanks requires a larger space. The series of gas top pressure fire water supply equipment produced by our company are new fixed fire extinguishing devices produced based on standards. The volume of the pneumatic water tank of this device is that of ordinary pneumatic water tanks. It saves floor space and has stable water supply pressure. It is an ideal large-scale emergency fire pneumatic water supply equipment.

Features
Series of gas top pressure fire water supply equipment adopt programmable human-machine interface control technology, equipped with independent gas source and intuitive liquid level display device, effectively ensuring the safe and stable operation of the equipment. Its main features are as follows
The product has advanced multi-functional programming control, the screen displays the operating status, can receive a variety of fire signals and can be networked with the fire center.
The product is equipped with two power interfaces and has automatic switching function.
The device is equipped with a dry battery backup power supply, which can still operate normally under fire alarm and power outage conditions.
The equipment has a compact structure, small footprint and is easy to use.
Safe and reliable, complete protection functions ensure foolproof operation.
The product can store
minutes of fire-fighting water and can replace indoor fire-fighting water tanks. It has the advantages of low investment, short construction period, simple construction and installation, and easy realization of automatic control.
The volume of the pneumatic water tank required for the same effective fire-fighting water consumption is smaller than that of ordinary pneumatic water supply equipment. The volume ratio of the gas volume to the water volume in the gas pressure water tank of the gas top pressure equipment is about
:
. The ratio of the common type is about (

): (


) As shown in the figure
for a pneumatic water tank with a total volume of It can provide up to
effective fire-fighting water volume
The effective fire-fighting water volume provided by the top pressure equipment is supplied in a constant pressure manner (as shown in the figure
It is a good solution to the common fire-fighting air pressure water supply equipment in the air pressure water tank. When the total volume remains unchanged (mostly because the equipment floor area does not increase), in order to increase the supply of effective fire-fighting water, increasing the water supply pressure difference will bring inconvenience and cost waste to the pressure-bearing design of the pipe network
Based on its characteristics
, the air pressure water storage tank, an important part of the equipment, occupies a small area and can be placed on the ground floor or basement of the building. It is especially suitable for low-rise buildings, light-weight material buildings, factories, warehouses and buildings where it is inconvenient to install high-level water tanks
The power air source system of the top pressure equipment is relatively independent of the water supply pipe network and only starts working when fire protection is needed. Therefore, it can achieve the characteristics of daily stable pressure working pressure being lower than fire fighting working pressure (as shown in the figure
relatively Ordinary air pressure water supply equipment greatly reduces daily operating costs.
The overall cost of the system is low. Because under the same water supply requirements, the total volume of the equipment’s air pressure water tank is greatly reduced, the floor space is small, and the fire protection facilities connected to it have a pressure-bearing level of It is well controlled and can even be appropriately reduced. The use of this type of equipment can benefit the entire automatic sprinkler system in terms of design, installation, and use.

Uses
Gas top pressure fire water supply equipment is used for fire fighting
Minute emergency fire extinguishing, suitable for hotels, hotels, entertainment venues, warehouses, residences, especially suitable for airports, earthquake zone buildings, hidden projects, temporary buildings and architectural art Buildings that require high-level water tanks are not suitable for installation.
Gas top-pressure fire water supply equipment is advanced, reliable, practical and economical fire water supply equipment.
Gas top-pressure fire water supply equipment has the above characteristics, making this type of fire water supply equipment In recent years, the equipment has been increasingly accepted and recognized by design departments and users. Its promotion is in line with the current requirements for creating a conservation-oriented society.

Working principle of the equipment
/> In the fire gas top pressure water supply equipment, the fire pressure water tank is a water storage component, and its effective water volume is the minimum requirement
. The pressure water tanks are all air-supplemented pressure water tanks. This type of equipment is provided by large pressure water tanks
For the initial water consumption of firefighting, there is no fire pump set, only a firefighting voltage stabilizing pump set. The main difference is that the gas top pressure equipment uses a high-pressure gas cylinder set to store the power gas source during firefighting work, and the power gas source and air pressure The water tank is separated. When the fire-fighting command arrives, the top-pressure system is activated to input compressed gas that meets the fire-fighting working pressure into the pneumatic water tank, and the fire-fighting water in the tank is replaced and discharged. The fire-fighting water is supplied to the fire-fighting components in a constant pressure state.
Copy
During daily operation, the pressure-stabilizing pump sends water to the pipe network and the pneumatic water tank. When the liquid level in the pneumatic water tank reaches the upper limit of the set value, the water replenishing pump stops working. The air supply system works when the pressure is insufficient. When the pressure rises to the upper limit of the stable pressure, the air supply stops. Usually, the pressure of the pipe network drops due to water leakage in the system. The liquid level controller controls the steady pressure pump to start the water replenishment system. If the air volume is missing, the pressure controller controls the air replenishment system (air compressor) to start and stop the air replenishment. In this way, the air pressure water tank can be filled with air every day. Liquid balance, pressure and liquid level interlocking. When a fire breaks out, the fire signal is input, and the gas pressure system works to decompress and release the power gas source, evenly fill it into the air pressure water tank, push the water into the fire pipe network, and provide no less than
Fire water.
