Background technology
The connecing of fire hose is buckled has 65 types, 80 types, 90 types, 100 types, 150 types and 300 types by bore point；Water band is by connecing
Buckle on mouth is sequentially connected, and after fire occurs, fireman need to reach the spot in time, the connection water band raced against time, and is approached
Burning things which may cause a fire disaster, strive for going out above-water method in time, rescue people's life and property.The problem of existing is that, when actually putting out a fire, water band connection disappears
After anti-car, water pump starts water outlet of pressurizeing, water band can rapid expansion successively paragraph by paragraph, but can not timely water outlet, its main cause is water
Air in band hinders the flowing of water, causes water discharging time to extend, is delayed the quality time of above-water method, is unfavorable for the people
Life and property timely treatment.
Utility model content
A kind of fire hose that the purpose of this utility model is in view of the shortcomings of the prior art and provided is vented to connect automatically to be buckled,
The utility model uses buckles setting air bleeding valve in connecing for fire hose, and when water pump starts water outlet of pressurizeing, water band is interior to obtain air meeting
Emptied paragraph by paragraph by air bleeding valve, and air bleeding valve is voluntarily closed in the presence of hydraulic pressure, is reduced the resistance of air in water band, is made water
Flowing accelerate, shorten water discharging time, in time go out above-water method save valuable time.
Realizing the concrete technical scheme of the utility model purpose is：
Automatically exhaust is connect and buckled a kind of fire hose, and its feature connects including water band is buckled and air bleeding valve, and the water band, which connects, to be buckled by connecing
Buckle position is formed with water receiving band position, and it connects buckle position and is provided with the delivery valve seat penetrated with barrel, and delivery valve seat is provided with interior spiral shell
Line；The air bleeding valve is made up of bonnet, valve element, spring and thrust ring, and bonnet is provided with external screw thread, valve opening and internal thread, thrust
Ring is provided with external screw thread, and spring and thrust ring are sleeved on valve element, valve element located at bonnet valve opening in, the external screw thread of thrust ring with
The internal thread engagement of bonnet；
The air bleeding valve is connect in the delivery valve seat buckled located at water band, and the external screw thread of bonnet connects with water band and buckled on air bleeding valve
The internal thread engagement of delivery valve seat；It is two or more that described water band, which connects the delivery valve seat buckled on barrel,.
The utility model uses and in connecing for fire hose buckles setting air bleeding valve, when water pump starts water outlet of pressurizeing, in water band
Obtaining air can be emptied by air bleeding valve paragraph by paragraph, and air bleeding valve is voluntarily closed in the presence of hydraulic pressure, reduces air in water band
Resistance, accelerate the flowing of water, shorten water discharging time, valuable time is saved to go out above-water method in time.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is close-up schematic view at Fig. 1 A.
Embodiment
Refering to Fig. 1, Fig. 2, the utility model connects including water band buckles 1 and air bleeding valve 2, and the water band, which connects, buckles 1 by connecing buckle position
11 are formed with water receiving band position 12, and it connects buckle position 11 and is provided with the delivery valve seat 111 penetrated with barrel, is set on delivery valve seat 111
There is internal thread；The air bleeding valve 2 is made up of bonnet 21, valve element 22, spring 23 and thrust ring 24, bonnet 21 be provided with external screw thread,
Valve opening and internal thread, thrust ring 24 are provided with external screw thread, and spring 23 and thrust ring 24 are sleeved on valve element 22, and valve element 22 is located at valve
In the valve opening of cap 21, the external screw thread of thrust ring 24 engages with the internal thread of bonnet 21；
The air bleeding valve 2 is connect in the delivery valve seat 111 for buckleing 1 located at water band, and on air bleeding valve 2 bonnet 21 external screw thread and water
Band connects the internal thread engagement for buckleing delivery valve seat 111 on 1；
It is two or more that described water band, which connects the delivery valve seat 111 buckled on 1 barrel,.
The utility model so uses：
Refering to Fig. 1, Fig. 2, in use, the excessively multiple water bands of a plurality of water band logical connect and buckle 1 water receiving band position 12 and be sequentially connected, water
After band connection fire fighting truck, water pump starts water outlet of pressurizeing, and water band rapid successively paragraph by paragraph can expand, the air warp in the expansion arc water band
Water band connects the air gap discharge buckled on 1 between delivery valve seat 111 and the valve element 22 of air bleeding valve 2, and now, air effect is in valve element 22
Power is not enough to overcome elastic force of the spring 23 to valve element 22, when the pressure flow in water band is to 2 position of air bleeding valve, because hydraulic pressure is made
Power for valve element 22 is more than elastic force of the spring 23 to valve element 22, and valve element 22 overcomes the elastic force of spring 23 to close bonnet 21, arranges
Air gap closing between air valve seat 111 and valve element 22, the press water in water band, which flows to rapidly next water saving band and connect, buckles 1, shortens
Water discharging time extends, and valuable time has been saved to go out above-water method.
Refering to Fig. 1, Fig. 2, when water pump pressurization water outlet terminates, the inner spring 23 of air bleeding valve 2 acts on valve element 22, elastic force it is extensive,
Valve element 22 resets, and water band connects the air gap buckled on 1 between delivery valve seat 111 and the valve element 22 of air bleeding valve 2 and is again turned on.
Refering to Fig. 1, Fig. 2, air bleeding valve 2 of the present utility model is hidden in water band and connect in the delivery valve seat 111 for buckleing 1, air bleeding valve 2
Without exsertion part, avoid and broken caused by possibility during fire-fighting fire extinguishing.
Refering to Fig. 1, Fig. 2, to meet the needs of different bore water bands exhausts, delivery valve seat 111, which is arranged on water band and connect, buckles 1
The both sides of wall or more sides.
In actual test, using 80 type water bands, in the water supply line of 400 meters of continuous length, using the utility model
The water discharging time of delivery port can shift to an earlier date 20 seconds.
