PVC flame-retardant and explosion-proof water bag hooks for coal mine tunnels. Soft water bag with good load-bearing capacity supports customization

Description :

Mining explosion-proof water bag and sink:Our company strictly produces and inspects products in accordance with the MT157 standard, which have the functions of flame retardancy, anti-static, good bearing capacity, no leakage, and easy installation. They are reliable products that effectively prevent the spread of combustible gases and coal dust explosions in coal mines Complete specifications

There are 30L, 40L, 50L, 60L, 80L and other national standard water bag sinks with complete specifications!

　　1、 Technical requirements

　　1. Water bags and sinks shall comply with the provisions of this standard and shall be manufactured according to the approved drawings and documents in accordance with the prescribed procedures. Purchased materials should have a certificate of conformity and can only be used after passing inspection.

　　2. The specifications and dimensions of water bags and sinks should comply with the requirements in Table 1, and the actual water capacity should not be less than the nominal capacity.

　　chart

　　The water distribution characteristics should meet the following requirements:

　　(1) The explosion pressure required for the breakage of the sink (expressed as static pressure) shall not exceed 16 kPa; The required explosion pressure (expressed as static pressure) for the action of the water bag shall not exceed 12kPa;

　　(2) The action time for forming water mist shall not exceed 150ms;

　　(3) Duration of water mist: not less than 250ms for the sink and not less than 160ms for the water bag;

　　The explosion-proof performance should meet the following requirements: the explosion flame should not exceed 140m from the explosion source.

　　2、 Structure: YS water bag, long groove shape, firmly bonded at the semi-circular seam at the bottom, with a neat and smooth surface, as shown in Figure 1; YS sink, rectangular trapezoidal shape, one-time molding, smooth surface, as shown in Figure 2.

　　3、 Usage method

　　1. Water usage for the water shed:

　　Explosion proof water bag (tank) sheds are divided into centralized and decentralized (depending on the layout).

　　The water consumption of centralized water bag (trough) sheds is calculated based on the type of roadway surface, with the main water shed not less than 400L/m2 and the water shed not less than 200L/m2;

　　4、 Installation method

　　1. The installation method of the water bag (trough) shed can be suspended, supported, or mixed; The principle is: when subjected to explosive impact, water is prone to splashing out; The layout should comply with the following regulations:

　　When the cross-sectional area S is less than 10m2, NB/L × 100>=35%

　　When the cross-sectional area S is less than 10m2, NB/L × 100>=50%

　　When the cross-sectional area S is less than 10m2, NB/L × 100>=65%

　　In the formula, the number of water bags (grooves) on the N-row shed, the width of the windward section of the B-row shed, and the width of the horizontal roadway where the L-row shed is located;

　　2. The sum of the gap between the sink (bag) and the gap between the sink (bag) and the support or roadway wall shall not exceed 1.5m, and shall not exceed 1.8m. The gap between two water bags (grooves) shall not exceed 1.2m, and the distance between the edge of the water bag (groove) and the roadway wall, support, roof, or structure shall not be less than 0.1m,

　　The distance from the bottom of the sink (bag) to the top beam shall not exceed 1.6m. If it is greater than 1.6m, an additional water bag (slot) must be added above it.

　　5、 Management and precautions of sink (bag) shed

　　1. Regularly maintain the integrity of the water bag (tank) and the specified water volume, with the upper edge in a horizontal state to meet the design requirements;

　　2. Check every half a day;

　　3. The water bag (trough) shed is declared for auxiliary explosion-proof use.
