Water with a hook by a canvas belt, metal hook, half-rings.
③ hose for the bridge for laying the protective hose cross pedestrian traffic, it does not affect the normal running of the vehicle equipment, having a high strength, durable compression, clean and convenient.
④ more types of interfaces, the interface with water, teeth of the interface, Reducing interface, shaped, a threaded interface or the like. A hose and hose, hydrant, fire pump is connected, water guns and other spray device. Press the button structure can be divided, and threaded insert other.
⑤ trap use, one stream of water in order to separate the two strands over two strands or flow; the second is used as a switch, by means of trap can be turned on or off from the hose line water, the water pump does not need to perform switching, thereby shortening the time required for opening and closing the water flow, to ensure timely supply fire. Trap trap has two, three quarters water and water is three.
test rules
1, when tested in the same species, the same diameter, length of 1000 m with a water batch. From a random selection of 100 meters do visual inspection. In the most economical method of three samples taken, sample length should meet the requirements of paragraph 3.1.1.
2, the inner diameter specimens shall comply with this standard; weight per unit length of three samples and the arithmetic average of seepage should conform to this standard; one sample only one state the burst test and shall comply with the provisions of this standard.
3, when an inspection does not meet this standard if the provisions that allow for the re-inspection once. When the re-inspection is still the most economical way to extract doubling the sample. The results of the retest specimens shall comply with the provisions of this standard, otherwise unqualified.
4, when the supply and demand sides of a dispute over the quality of products, all costs of the arbitration inspection borne by the responsible party.
maintenance measures
use and maintenance of the fire hose:
First, hose connections, the fire hose jacket when Sheung with connection shall be a single layer of flexible protective material, and then fastened with galvanized wire or hose clamps.
Second, the use of hoses. When using the fire hose, should be connected with high pressure water from the pump in place close to, the water-filled hose should prevent sudden twisting or bending, while the interface water stop should prevent collision damage.
Third, water tape laying. When laying hose, to avoid sharp objects and folders various oils, higher ground when the vertical laying of water, when to use water with a hook, the laying of water through roads, should be fitted with water for the bridge, by rail when, following the track by the hose should avoid bad wheel was crushed with water intermittently supply.
Fourth, to prevent freezing. Winter season, when the court to suspend the fire water supply, water stop for the anti-icing, slow-running pumps need to keep a small amount of water.
Fifth, washed with water, with the water used to clean, the foam of the conveying hose, must careful washing, the protective rubber layer. Bring water to remove grease, use warm water to wash or soap, to freeze the hose, the first to use it to melt, then dry cleaning, no dry with no water storage volume accounts.
Note
Fire Hose Fire is a site with water hoses. Press materials can be divided into fire hose lining fire hose and unlined. Wherein linerless fire hose low pressure, high resistance, easy to leak, and easy to mold rot, short life, suitable for laying in a building fire; lining hose high pressure resistance, wear resistance, mold rot, durable durable, and difficult to leakage, small resistance, can be bent folded, free to move, easy to use, and is suitable for external fire laying oN fire .
Caution should fire hose:
1. Laying should avoid sudden turns, to prevent the reduction of the ability to withstand water pressure; should avoid twisting, to prevent rotation of the hose filled with water after the water with the button released interfaces.
2. After filling water to avoid drag force on the ground, to try to lift the moved position needs to be changed, to reduce wear and ground with water.
3. Should avoid contact with the oil, acid, alkali and other corrosive chemicals.
4. In a possible strong flame or radiant heat zone, should be cotton or linen with water.
5. After completion should be washed clean, the liner hose to hang drying, dry coil in a cool dry place.
6. Use of the process as they are damaged holes, apply water with a cloth bind tightly, as soon as possible after the darning or stick up; when there is visible damage, should immediately withdraw from combat.
7. When the vehicle needs by laying the hose, hose disposed in advance by site for the bridge.
8. For laying by rail, the following should be by rail.
9. Cold areas should be used outside of the building lined with water, bring water to avoid freezing.
fire hose attachment
is mainly water with an attachment means to connect and use the fire hose necessary accessories, including an interface, and the like trap.
1. Interface
is the interface with the water hose, fire pump, fire hydrant or mobile monitor linker. Interfaces mainly with water, teeth of the interface, bonnet, fixed interfaces internal thread, the external thread fixed interfaces, Reducing interface, profiled interface.
