GB impact Bomi closed

Anti-shock door poor are changed, change the pass, General Delta, Shandong Century Mining Equipment Co., Ltd. specializes in producing TEDA anti-shock doors, production technology continues to improve, with professional technical team, the production of anti-shock doors have short production cycle, the warranty period long, simple operation, and other advantages of anti-shock valve from parts door frames, doors, locking device, dumplings page and other components. 1, a sealed manner a "9" shaped cross section rubber seal 2, locking means provided two groups, one group is normally closed by a latching shaft, rotary handle; another group of emergency locking device, which functions when an impact force is greater than 294N, the moment, the door and the door closed, compression seals, locks into the lock cylinder, toggle double leaf springs, brake lock, preventing the door from the rebound; toggle key handle to release the lock outside. 3, door frames ranging from welding frame corners. 4, the upper doors equipped with three sets of ventilation shutter means that the shutter open floor there are three groups of 18 122mm diameter ventilation holes, and live outside the door with an automatic valve opening angle of 12 degrees hanging board. Each group of 2,000 cubic ventilation valve / h, the total ventilation rate of 6,000 cubic meters / h, according to wind speed 8m / s design, when used according to the need of underground blasting material library and total return air duct negative value, determine the ventilation valve number of groups, each group can adjust the shutter plate hanging Qi-angle fine-tuned to meet the optimum ventilation. When the library once the explosion occurred after the shock wave attenuation, as long as the residual pressure is greater than 20KPa, hanging plate pressure valve automatically closes again within 3-8s, and the outside world, the organization explode explosion flame spread shock, toxic gases to the outside roadway proliferation, discharged from the total return air duct. 5, the next page dumplings one-way thrust ball bearings, with spring folding intermediate, make sure the door is automatically closed. . Impact Bomi closed technical requirements: 1. The door should open the library, the design uses open to the right direction, to turn to the left, to the doors should centerline axis of symmetry changes in the location of parts 2. Doors Page board installation, the guarantee, lower hinge hole concentric page centerline parallel to the centerline of the inner surface of the leaf. 3. The door frame and hole in the wall as a whole, before pouring the concrete, fixed angle hinge page should check more positive, stable fixation, the assurance, lower hinge hole in the center pages in a vertical line, the degree of tolerance for different centers 2mm. 4. After installing doors and door frames should fit the plane and into a vertical, local gap within 3mm. 5. atresia, moving parts should always be injected hinges page grease, the components should be maintained at least once a year. 6. Exposed metal surfaces should be coated with rust red lead two times, orange paint twice, and the outer surface of the doors marked handle switch direction. 7. lifting doors, roof openings should be a corresponding embedded rings. 8. connection and door sealing strip, first with the all-purpose adhesive glue, then bolted. 9. The sealing strip should always be painted talc to prevent aging. Order anti-shock doors trusted professional production enterprises, Shandong Century Mining Equipment Co., Ltd.
