消防软管一般安装在室内，要进行独立的设置，使用的时候不会影响到其他的配置，可以保证。这样的消防设备您对它了解多少呢？下面从它的喷枪以及软管方面的内容了解起来。

The fire hose is generally installed indoors and should be set independently. When it is used, it will not affect other configurations and can ensure safety. How much do you know about such fire-fighting equipment? Let's learn from the professional contents of its spray gun and hose.

喷枪性能

Spray gun performance

喷枪应带有开关，且“开”与“关”的转换应由一个动作完成。

The spray gun shall be equipped with a switch, and the conversion between "on" and "off" shall be completed by one action.

使用水的喷枪应为直流型或直流喷雾混合型。

Spray guns using water shall be direct current type or direct current spray mixed type.

喷枪的螺纹应符合GBl97中内螺纹7H级、外螺纹8g级的要求。螺纹应表面光洁、牙形完整。

The thread of spray gun shall meet the requirements of grade 7h internal thread and grade 8g external thread in gbl97. The thread shall have smooth surface and complete tooth shape.

喷枪在软管卷盘1.5倍额定工作压力下不得产生明显变形或断裂现象。

The spray gun shall not produce obvious deformation or fracture under 1.5 times the rated working pressure of the hose reel.

喷枪应按相关规定，从离地面1.50m高处自由落下。试验后喷枪应无碎裂并能正常操作使用。

The spray gun shall fall freely from a height of 1.50M above the ground according to relevant regulations. After the test, the spray gun shall be free from fragmentation and can be operated normally.

使用二氧化碳的软管卷盘的喷枪，其握持部位应有隔热措施。二氧化碳软管卷盘的喷枪还应有除静电措施。

The holding part of the spray gun with carbon dioxide hose reel shall be provided with heat insulation measures. The spray gun of carbon dioxide hose reel shall also be provided with anti-static measures.

软管性能

Hose performance

软管的规格及其内径，长度和相应的极限偏差应符合规定。

The specification, inner diameter, length and corresponding limit deviation of the hose shall comply with the regulations.

软管的额定工作压力应与软管卷盘相同。软管的试验压力，爆破压力应分别为额定工作压力的1.5倍和3.0倍。分别不得有渗漏现象和破裂现象。

The rated working pressure of the hose shall be the same as that of the hose reel. The test pressure and bursting pressure of the hose shall be 1.5 times and 3.0 times of the rated working pressure respectively. There shall be no leakage and rupture respectively.

软管在额定工作压力下，外径的膨胀率应在-5%～+7%范围内。

Under the rated working pressure, the expansion rate of the outer diameter of the hose shall be within the range of -5% ～ +7%.

软管在额定工作压力下的轴向伸长率应在-6%～+10%范围内。

The axial elongation of the hose under the rated working pressure shall be within the range of -6% ～ +10%.

除二氧化碳卷盘的软管外，其余软管应按第5．8．3条规定弯曲。弯曲后其外径增加率不得大于初始值的10%。

Except for the hose of carbon dioxide reel, other hoses shall be bent according to article 5.8.3. The increase rate of outer diameter after bending shall not be greater than 10% of the initial value.

软管应按规定的条件进行低温试验。在-5℃的低温试验后，软管应能立即展开。无卷曲现象，并能再次缠绕，且在额定工作压力下无渗漏。在低温条件下工作和使用二氧化碳的软管其试验温度为-30℃。

The hose shall be subject to low temperature test under specified conditions. After the low temperature test at -5 ℃, the hose shall be able to be deployed immediately. There is no curl, and it can be wound again, and there is no leakage under the rated working pressure. The test temperature of hose working under low temperature and using carbon dioxide is -30 ℃.

软管衬里及覆盖层材料的物理机械性能应符合相应材料的标准或行业标准的规定。

The physical and mechanical properties of the hose lining and covering materials shall comply with the provisions of the national standards or industrial standards of the corresponding materials.

川消软管外表应无破损、划伤，局部隆起。

The appearance of Chuanxiao hose shall be free of damage, scratch and local uplift.
