Description
Technical Field
The invention relates to fire-fighting equipment, in particular to a decompression and pressure-stabilizing hydrant with a self-rescue rotary table outlet.
Background
Due to the limited urban area, high-rise buildings are gradually increasing. Therefore, the pressure of the water supply system is gradually reduced from eight to twelve layers, and the pressure is less than 0.5 to 0.8Mpa. Thus, each building has a large entresol floor without decompression and pressure stabilization fire hydrant, so that the cost is saved in terms of funds, and if a common single outlet D65 is adopted. On the one hand, the self-rescue cannot be realized, on the other hand, a professional must arrive at the scene when the fire is saved, and if the same-diameter double-outlet is adopted, the self-rescue cannot be realized. Especially, it is difficult to achieve the purpose of fire fighting at corners. Therefore, the self-rescue rotary table outlet fire hydrant can be designed to meet the purposes of self rescue and cost saving.
The traditional indoor fire hydrant has hardly satisfied the fire extinguishing device of the present high-rise civil building, and has hardly satisfied the requirement of setting pressure reducing and stabilizing device under the static pressure and dynamic pressure (when the pressure of the fire hydrant is between 0.50 and 1.00 MPa). This is because the outflow rate of the bolt mouth pressure exceeding 0.5MPa can generate a huge reaction force at the water gun mouth, exceeding the control capacity of fire fighting (self-rescue personnel). Therefore, pressure reduction and stabilization are necessary. However, the pressure is gradually reduced from eight layers to more than twelve layers on the high-rise, so that the pressure-reducing and pressure-stabilizing hydrant does not need to be selected, and the cost is high, the interior is complex, the flow is limited, and the like.
In recent years, the rapid development of socioeconomic performance makes high-rise buildings a central trend in the development of the building field. The structural form, construction technology and safety fire prevention of the high-rise building are continuously innovated and practiced under the support of the current scientific technology. Under the condition of meeting the requirements of living and living of urban residents, the space of the high-rise building product device is fully developed and utilized, and safety and fire prevention are well achieved.
Therefore, the high-rise building must be provided with an indoor and an outdoor hydrant water supply system, and double-valve double-outlet type hydrants must be adopted in unit houses with eighteen layers and below. The fire hydrant should adopt the same model specification, and the fire hydrant's mouth diameter is 65mm, and hosepipe length should not exceed 25m, and the squirt nozzle mouth should not be less than 19mm. When the building height is not more than 100m, the hydrostatic pressure of the most unfavorable fire hydrant of the high-rise building is not lower than 0.07MPa, and when the building height is more than 100m, the hydrostatic pressure of the most unfavorable fire hydrant of the high-rise building is not lower than 0.15MPa. Therefore, a pressurizing device is provided to achieve the aim of fire extinguishment. However, in narrow places, particularly in places with turning angles, the space is difficult to spread by directly using a water hose with the length of 65 mm. The self-rescue turntable pressure-reducing and pressure-stabilizing hydrant can be used for serving. The method is a process from failing to save oneself to saving oneself without any time, so to speak, adding flowers to the whole life. The functions are more, the method is more, and the fire extinguishing quality is improved. Therefore, the fire extinguishing agent is an inevitable result of the current social development and is also an inevitable product of actual fire extinguishment.
Fire hydrant is a fixed fire extinguishing tool. The main functions are to control combustible material, isolate combustion supporting material and eliminate ignition source. The fire hydrant system comprises: the fire hydrant system comprises an outdoor fire hydrant system, an indoor fire hydrant system, a fire extinguishing system, an automatic spraying system, a water cannon system, a gas fire extinguishing system, a fire detecting system, a water mist system and the like. The fire hydrant is mainly used for a fire engine to take water from a municipal water supply pipe network or an outdoor fire water supply pipe network for fire extinguishment. So, the hydrant system is also one of important fire-fighting facilities for extinguishing fire. The more and better the function of the fire extinguishing agent is, the more is the fire extinguishing agent favorable, and the fire extinguishing agent can be accepted and used by non-fire-fighting professionals. Therefore, the self-rescue turntable pressure-reducing and pressure-stabilizing hydrant is convenient to apply and can be widely used.
The commonly used hydrant SN65 is a common hydrant, and can be opened and closed by rotating a hand wheel. On the basis of the common indoor hydrant, a decompression and pressure stabilization device is added. Consists of decompression flap, compression eliminating spring, cover and other parts.
Double also commonly used double outlet hydrants and double ended hydrants. The front and the back are double valves (single valves) and double outlets with the same diameter. The fire hose has strong specialty, damages to thin decorative materials with small paper strength, and is inflexible in turning narrow places of rooms, so that the aim of truly extinguishing fire is not achieved. So in order to meet the requirements of fire extinguishment and less damage to property, the current indoor DN65 outlet reducing hydrant is designed and improved.
In one aspect, a plateau with a 24 meter target height and a volume less than 5000 cubic meters can be filled with water columns to any position in a room by using a water gun.
On the other hand, fire can be extinguished in time for thin and low-strength articles. This is because there are two outlet diameters 65 and 25. The pressure is reduced to 0.8Mpa by 1.6Mpa, which satisfies the connection of the reel and the hose. Convenient, reliable, flexible and practical. The problems that the traditional fire fighting waiting time is long, the special fire fighting water belt is inconvenient to use, the water quantity is too large, indoor building articles are damaged, and the like are greatly changed. It can be said that a double-purpose one-arrow double-engraving can be used for achieving the effect of twice the result with half effort.
