Abstract
The utility model relates to a pressurization water supply connector for firefighting, which comprises water inlet pipes and a water outlet pipe. Fire hose joints are arranged at inlets of the water inlet pipes and an outlet of the water outlet pip, the inlet of the water outlet pipe is communicated with the inlets of at least two water inlet pipes, each water inlet pipe is provided with a check valve, a relieve valve and a pressure gauge are arranged on the water outlet pipe, the relief valve is a spiral relief valve, the fire hose joints at the inlets of the water inlet pipes are female joints, the fire hose joint at the outlet of the water outlet pipe is a male joint, and the outer diameter of the water outlet pipe is larger than that of each water inlet pipe. The pressurization water supply connector is simple in structure, convenient in use, capable of supplying water in a pressurized manner, and safe in water supply.
Description
(1), technical field: the utility model relates to a kind of connector, particularly a kind of fire-fighting pressurized water supply connector.
(2), background technology: at present, the high-rise fire extinguishing of fire fighting truck way of supplying water has following problem: one, commonly used lay to high level that the fire extinguishing water supply flow of single mains water band circuit is little, pressure is low, can not guarantee the place ahead hydraulic giant, the effective jetting fire extinguishing of water cannon needs.Two, when supplying water control not at that time, very easily cause high pressure water to pour in down a chimney in the water pump system, cause the reverse high speed reverse rotation of fire fighting truck water pump system, thereby make device damage, cause very big economic loss, influence action.Three, after the water supply line bearing certain pressure, can produce huge water hammer impulsive contact force during the water band pressure release of vertical water supply line connection, make the swing out of control of water band and joint, very easily the people is produced injury.Four, pour in down a chimney in the water pump system for preventing high pressure water, need a plurality of manpower matching coordinatives when supplying water operation, effort, time-consuming, numerous and diverse, efficient is poor, has wasted limited combat forces.In a word, according to numerous fire fighters reflection, existing way of supplying water causes to be ruined the thing that car hurts sb.'s feelings and takes place often.
(3), utility model content:
The technical problems to be solved in the utility model is: at the prior art deficiency, but provide the fire-fighting pressurized water supply connector of a kind of pressurized water supply simple in structure, easy to use, safety water supply.
The technical solution of the utility model:
A kind of fire-fighting pressurized water supply connector contains water inlet pipe and outlet pipe, and the inlet of water inlet pipe and the exit of outlet pipe are provided with the fire hose connector, and the inlet of outlet pipe is communicated with the outlet of two water inlet pipes at least, all is provided with check-valves on each root water inlet pipe.
Outlet pipe is provided with relief valve.
Relief valve is spiral relief valve.
Outlet pipe is provided with Pressure gauge.
The fire hose connector of the porch of water inlet pipe is female joint, and the fire hose connector in the exit of outlet pipe is male joint.
The external diameter of outlet pipe is greater than the external diameter of water inlet pipe.
The radical of water inlet pipe is two, or is three, or is four.
Water inlet pipe and outlet pipe are coating steel pipe.
The beneficial effects of the utility model:
1. the inlet of outlet pipe of the present utility model is communicated with the outlet of two water inlet pipes at least, multi-strand flow can be accumulated one current like this, the flow of water and the pressure of water supply have been increased, make discharge and hydraulic pressure increase many times, effectively guarantee the effective range of the place ahead hydraulic giant and water cannon, improved fire-fighting efficiency widely.
2. all be provided with check-valves on each root water inlet pipe of the present utility model, check-valves can avoid high pressure water to be back in the water pump system, prevents that water pump system is damaged.
3. outlet pipe of the present utility model is provided with relief valve, and relief valve is spiral relief valve, during sluicing, can slowly open relief valve gradually and sluice, active force is little, easy to control, can disorderly not swing, and avoided the excessive collision of pressure to hurt sb.'s feelings, relief valve also can be connected with the water band, recirculation water is imported in the fire fighting truck, not only saved water resource, and free from environmental pollution.
4, outlet pipe of the present utility model is provided with Pressure gauge, and the pressure data of fire fighting supply can be provided at any time, is convenient to fire fighter operation, control, during water supply, only needs that driver one people pressurizes, reduces pressure, cuts off the water, the pressure release operation gets final product, and has saved human resources.
5, the exit of the inlet of water inlet pipe of the present utility model and outlet pipe is provided with the fire hose connector, can be connected with various model fire fighting truck delivery ports, water band fast, and is easy to operate.The utility model has solved the hang-up of high building fire-proof water supply security, and its practicality, security, stability, resistance to pressure, reliability, robustness, practicality are all very strong, easily promote the use of.
(4), description of drawings:
Fig. 1 is the structural representation of fire-fighting pressurized water supply connector.
(5), the specific embodiment:
Referring to Fig. 1, among the figure, fire-fighting pressurized water supply connector contains water inlet pipe 1,2 and outlet pipe 3, the inlet of water inlet pipe 1,2 and the exit of outlet pipe 3 are provided with fire hose connector 4,5,6, the inlet of outlet pipe 3 is communicated with the outlet of two water inlet pipes 1,2, be respectively equipped with check-valves 7 on the water inlet pipe 1,2, its model of 8(is D65mm).
It is D25mm that outlet pipe 3 is provided with its model of relief valve 9(, and material is a copper).
The fire hose connector 4,5 of the porch of water inlet pipe 1,2 is female joint (its model is D65mm, is aluminum alloy joint), and the fire hose connector 6 in the exit of outlet pipe 3 is male joint, (its model is D80mm, is aluminum alloy joint).
Water inlet pipe 1, its model of 2(are D65mm) and its model of outlet pipe 3(be D80mm) for coating steel pipe, the external diameter of outlet pipe 3 is greater than the external diameter of water inlet pipe 1,2.
