2016 Jining Guolong supplies 20L explosion-proof water bags

Supply explosion-proof water bags, specializing in the production of explosion-proof water bags, explosion-proof water bags wholesale
Explosion-proof water bags for coal mines, explosion-proof water tanks: high-quality products produced and inspected strictly in accordance with - standards, with flame retardant, anti-static, load-bearing capacity The explosion-proof water bag explosion-proof water tank is a reliable product that effectively prevents the spread of flammable gas and coal dust explosions underground in coal mines.
Product Description:
Mining explosion-proof water bag is an installation container used in coal mines. The water bag shed is composed according to the installation technical requirements and can effectively isolate the spread of gas and coal dust explosions. The materials used to make water bags It has safety properties such as flame retardant and anti-static.
1. Technical requirements
Water bags and water tanks should comply with the provisions of this standard and should be manufactured according to approved drawings and documents according to prescribed procedures. Outsourced materials should have certificates of quality and must pass inspection before they can be used.
The specifications and dimensions of water bags and water tanks should comply with the requirements in the table. The actual water capacity shall not be less than the nominal volume.

The water distribution characteristics should meet the following Requirements:
. The explosion pressure (expressed as static pressure) required for the water tank to break must not be greater than the explosion pressure (expressed as static pressure) required for the action of the water bag.
The action time to form the optimal water mist must not be greater. Greater than
, the optimal water mist duration: the water tank should not be less than the water bag, the optimal water mist dispersion length should not be less than
, the optimal water mist dispersion width should not be less than.< br/>. The optimal water mist dispersion height shall not be less than .
The explosion-proof performance should meet the following requirements: the explosion flame from the explosion source shall not exceed.
2. Structure: water bag, long trough shape, semicircular bottom seam, firmly bonded, neat and smooth surface as shown in the picture. Sink, rectangular trapezoid, molded in one step, smooth surface as shown in the picture.
3. How to use
Water consumption of the water shed:
Explosion-proof water bag (tank) sheds are divided into centralized and decentralized types (depending on the layout).
The water consumption of the centralized water bag (tank) shed is calculated according to the type of tunnel section. The main water shed is not less than/the auxiliary water shed is not less than/
The water consumption of the decentralized water tank (bag) shed is calculated according to the shed area. The volume of the lane space occupied shall be calculated as not less than ./.
The location of water boron:
The water bag (trough) shed should be set up in the straight roadway
The distance between the water bag (trough) shed and the turning point of the roadway intersection should be - The distance from the air door must be greater than
. The distance between the first row of centralized water sheds and the working surface must be maintained. The distance between the first row of distributed water sheds and the working surface must be maintained
. Auxiliary explosion proof should be provided. The laneway of the water shed should be equipped with multiple groups of water sheds. The distance between each group should not be greater than
. The distance between rows of water sheds and the length of the water shed area are:
. The distance between rows of centralized water sheds is.-.dispersed The distance between the two water bag (trough) groups dispersed along the tunnel is .
4. Installation method
The installation method of water bag (trough) shed: it can be hanging type or top-supporting type, or it can be mixed type. The principle is: water is easy to spill out when affected by the impact of explosion. The layout should comply with the following regulations:
Section＜hour%
Section＜hour%
Section＜hour%
The number of water bags (troughs) on the row shed in the formula - the water shed faces the wind Section width - the width of the horizontal tunnel where the water shed is located
, the sum of the gap between the water tank (bag) and the gap between the water tank (bag) and the bracket or tunnel wall shall not exceed. No more than two water bags (tank) ) shall not be greater than . The distance between the edge of the water bag (trough) and the tunnel wall, bracket, roof, or structure shall not be less than . The distance from the bottom of the water trough (bag) to the roof beam shall not be greater than . If greater than Add a water bag (trough) above the water bag (trough). The distance between the water shed and the roadway rail surface should not be smaller than the same height. When the roof needs to be raised, the tunnel section in the water shed area should be consistent with the tunnel sections at the front and rear.
2. The hook position of the hanging water bag (trough) should be aligned with the round steel hooks arranged in opposite directions at an angle of 10 degrees.
5. Management and precautions for the water tank (bag) shed
It is necessary to always keep the water bag (trough) intact and the specified amount of water. The upper edge must be in a horizontal state to meet the design requirements
. Every time The water bag (tank) shed is declared to be used as auxiliary flameproofing after half inspection.
6. Packaging, transportation and storage
Product packaging should comply with the relevant regulations for railway and road transportation (only one water bag should be packed in a woven bag).
The water bag should prevent mechanical impact and friction during transportation and avoid sun and rain.
. Products should be stored in well-ventilated warehouses. The stacking should not be too high to avoid affecting the quality of use. Contact with substances that damage the quality of rubber and plastics should be avoided. Direct sunlight and rain should be avoided. The storage temperature should be between -℃~℃. Relative temperature between -﹪between and away from the heat source.
. Explosion-proof water bags must have flame-retardant or flame-retardant and anti-static functions and must have the carrying capacity to carry a corresponding volume of water without leakage.
According to different requirements, make water bags with different volume specifications and make corresponding wind buckles on both sides to facilitate the installation and replacement of shaped movable hooks in the water bag shed. Iron bars of corresponding specifications need to be inserted on both sides of the water bag to increase the carrying capacity of the water bag.
The water bag must be tightened and hung securely, the force must be even and the buckles must be hung without any omissions.
