消防軟管一般安裝在室內，要進行獨立的設置，使用的時候不會影響到其他的配置，可以保證。這樣的消防設備您對它了解多少呢？下面從它的噴槍以及軟管方面的內容了解起來。
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.
噴槍性能
Spray gun performance
噴槍應帶有開關，且“開”與“關”的轉換應由一個動作完成。
The spray gun shall be equipped with a switch, and the conversion between "on" and "off" shall be completed by one action.
使用水的噴槍應為直流型或直流噴霧混合型。
Spray guns using water shall be direct current type or direct current spray mixed type.
噴槍的螺紋應符合GBl97中內螺紋7H級、外螺紋8g級的要求。螺紋應表面光潔、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.
噴槍在軟管卷盤1.5倍額定工作壓力下不得產生明顯變形或斷裂現象。
The spray gun shall not produce obvious deformation or fracture under 1.5 times the rated working pressure of the hose reel.
噴槍應按相關規定，從離地面1.50m高處自由落下。試驗后噴槍應無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.
使用二氧化碳的軟管卷盤的噴槍，其握持部位應有隔熱措施。二氧化碳軟管卷盤的噴槍還應有除靜電措施。
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.
軟管性能
Hose performance
軟管的規格及其內徑，長度和相應的極限偏差應符合規定。
The specification, inner diameter, length and corresponding limit deviation of the hose shall comply with the regulations.
軟管的額定工作壓力應與軟管卷盤相同。軟管的試驗壓力，爆破壓力應分別為額定工作壓力的1.5倍和3.0倍。分別不得有滲漏現象和破裂現象。
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.
軟管在額定工作壓力下，外徑的膨脹率應在-5%～+7%范圍內。
Under the rated working pressure, the expansion rate of the outer diameter of the hose shall be within the range of -5% ～ +7%.
軟管在額定工作壓力下的軸向伸長率應在-6%～+10%范圍內。
The axial elongation of the hose under the rated working pressure shall be within the range of -6% ～ +10%.
除二氧化碳卷盤的軟管外，其余軟管應按第5．8．3條規定彎曲。彎曲后其外徑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.
軟管應按規定的條件進行低溫試驗。在-5℃的低溫試驗后，軟管應能立即展開。無卷曲現象，并能再次纏繞，且在額定工作壓力下無滲漏。在低溫條件下工作和使用二氧化碳的軟管其試驗溫度為-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 ℃.
軟管襯里及覆蓋層材料的物理機械性能應符合相應材料的標準或行業標準的規定。
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.
The appearance of Chuanxiao hose shall be free of damage, scratch and local uplift.
