Coal injection sealing device Note 1, the use of coal seam water sealing is fast and simple. Just the job site waterways and sealing device connectivity, the sealing device is fully inserted into the borehole at a certain pressure, sealing device hose expansion to achieve sealing, water breaking coal. 2, seam sealing water can be reused several times after the injection relieved the pressure, sealing device can be recovered, remove sealing device. 3, sending plug sealing device and recovery operation with pressure sealing device is prohibited. 4, when the sealing is not allowed to work in front of people jobs. 5, sealing must be straight using do not discount the weight. 6, regulate the use of the good sequence valve (opening pressure should be greater than 1MPA) tunnel injection sealing device, have a pressure gauge to monitor pipeline pressure is higher than the working pressure of the water is prohibited, the job is completed to remove coal injection pressure water pipe sealing device, sealing device to be anhydrous relief, restitution water sealing device, sealing is finishing out of standby. Steel production process used in the metallurgical industry to the equipment continuous casting equipment, into electric converter and converter furnace, where the requirement is for a hose armored exterior for cooling compartment temperature burn gas drainage water resistant sealing device , pumps and pumping stations to use, in addition to the pressure required to achieve acceptable, anti-aging is going to meet the requirements. Sealing water tunnel, a water sealing device, Bo-Bo-rubber provided by Hengshui Rubber Products Limited. Hengshui Bo-Rubber Products Co., Ltd.
