Rubber water sealing device, ZF-A22 rubber expansion pipe, hose fittings, rubber products

Mine water Mine water sealing device sealing device price, coal mine water sealing device manufacturers, coal water sealing device with a model, the product uses: Coal water, dust, reducing coal pressure, breaking coal, gas and other emissions . Second, the product features: 1, the water into the coal, the release of part of the gas, effectively reducing coal gas content; 2, to achieve the effect of water, dust can be reduced by 80%, improving workers' working environment, to prevent dust explosion; 3, moist coal, prevent spontaneous combustion in coal; 4, high-pressure water, broken coal, reduce fire industrial products, reduce costs and increase workers' sense of security; 5, sealing is broken coal use, can effectively prevent coal and gas outburst and explosion . Third, the product structure: sealing rubber expansion consists of a high pressure hose, safety valve, quick coupling components. Fourth, the technical parameters: Sealing diameter: 30-120mm (according to user needs processing) Working Pressure: 1-20MPa (according to user needs processing) safety valve starting pressure: 0.4-0.5MPa Work flow: water per hour 4- 4.5 tons sealing depth: 0.5-8m hose expansion coefficient: 60% -100% Model ID OD expanded the scope of the free state aperture in a free state at the operating pressure of work status compressive strength test pressure burst pressure ZF enhance -19 19 ± 0.5 40 ± 2 60 45 20 30 40 ZF enhance -22 22 ± 0.5 48 ± 2 80 50 20 30 40 ZF enhance -22 22 ± 0.5 39 ± 2 80 50 6 12 24 ZF enhance -32 32 ± 0.5 50 ± 2 90 60 6 12 24 ZF enhance -38 38 ± 0.5 55 ± 2 95 65 5 10 20 ZF enhance -45 45 ± 0.5 63 ± 2 100 75 4 8 16 ZF enhance -51 51 ± 0.5 90 ± 2 110 90 4 8 16 V. Using the methods and precautions: 1, the use of coal seam water sealing is fast and simple. Just the job site connecting waterways and sealing, the sealing device is fully inserted into the borehole, under pressure, to achieve expansion sealing device sealing hose, water breaking coal. 2, seam sealing water can be reused several times after the injection pressure is removed, the sealing device can be recovered, remove the sealing device. 3, sending plug sealing device and recycling with pressure sealing operation is prohibited. 4, the sealing device was not allowed to work the front of the job.
