Explosion-proof floor drain is a floor drain used in special occasions, and is generally used in civil air defense areas.
1 、原理加厚铸造主体，利用无机械原理水封密封。 Analysis of the advantages of explosion-proof floor drains: 1. The principle is to thicken the casting body and use a non-mechanical principle water seal to seal. 、材质：优质环保材料，本体由不锈钢或黄铜制成，精致、高档；密封体由优质 ABS （工程塑料）制成，耐冲击、耐高温 80 °。 2. Material: High-quality environmental protection material, the body is made of stainless steel or brass, exquisite and high-grade; the sealing body is made of high-quality ABS (engineering plastic), impact resistance, high temperature 80 °. 、排水量大，绝排水量需要超过 1.1 升 / 秒（国家建材检测中心检验报告），洗衣机大排水量时也不会返水。 3 , large drainage, absolute drainage needs to exceed 1.1 liters / second (National Building Materials Testing Center inspection report), washing machines will not return water when the large drainage. 、 清理方便可拆卸式防臭内芯，只需定期将内芯取出在水中清洗，清理十分方便！ 4. Convenient cleaning. Detachable deodorant inner core. You only need to take out the inner core and clean it in water regularly. Cleaning is very convenient!
Explosion-proof floor drain material
PVC 、锌合金、陶瓷、铸铝、不锈钢、黄铜、铜合金等材质。 Mainly cast iron, PVC , zinc alloy, ceramic, cast aluminum, stainless steel, brass, copper alloy and other materials.
1 , cast iron: cheap, easy to rust, unsightly, hanging sticky dirt after rust, not easy to clean;
PVC: 价格便宜，易受温度影响发生变形，耐划伤和冲击性较差，不美观； 2 , PVC: cheap, susceptible to temperature deformation, scratch resistance and impact resistance is poor, unsightly;
3 , zinc alloy: cheap, easy to corrode;
4 , ceramics: cheap, corrosion-resistant, not impact-resistant;
5. Cast aluminum: mid-range price, light weight and rough;
6 , stainless steel: affordable, beautiful and durable;
7. Copper alloy: affordable and practical.
8. Brass: heavy, high-grade, high price, the surface can be electroplated.
60 度即可完全密闭锁紧（反之逆时针方向旋转 60 度即可退出），防爆地漏  密闭时可防止爆炸冲击波及其它有毒气体由管道进入防护体，起到安全防护作用，战时该地段染毒需进行清洗时，将防爆地漏打开，进行排水，即可冲洗。 The explosion-proof floor drain is installed at the end of the protection zone on the drain pipe that leads to the area outside the air defense protection zone. It is normally closed. The drain core is placed in the valve cavity and rotated about 60 degrees clockwise to completely close and lock ( Conversely , it can be exited by rotating 60 degrees counterclockwise. ) The explosion-proof floor drain  can prevent explosion shock waves and other toxic gases from entering the protective body from the pipeline when it is closed. It plays a role of safety protection. Open the explosion-proof floor drain, drain, and rinse.
