Detailed Product Description: | Mine anti-shock anti-shock valve gate valve gate supply mine mine mine gate door manufacturers price anti-shock valve for underground, from the anti-shock, adjustable air volume required for the Treasury and isolation effect. The anti-shock valve from the door frames, doors, locking device, dumplings pages and other components. Mine explosion-proof anti-shock structure of a main valve products, ranging from the corner of the door frame welding frame structure. 2, the door is equipped with three sets of upper ventilation shutter means that the shutter open floor there are three groups of 18 122mm diameter ventilation holes, live outside door open 12 degrees angle with automatic shutter hanging boards. Each valve ventilation rate of 2,000 cubic meters / h, the total ventilation rate of 6000 cubic meters / h, wind speed at 8m / s for the design, when used according to library needs underground blasting material and total return air duct negative value that determines the ventilation valve number of groups, each group can adjust the shutter hanging plate Zhang Qi angle fine-tuned to meet the optimum ventilation. When the library in the event of unforeseen circumstances, the shock wave is attenuated and residual pressure as long as more than 20KPa, the shutter is pressed and then suspended deflectors 3-8s to automatically shut down, and the outside world, play a protective role, by the total return air duct discharge. 3, the latch means is provided two groups, one group is normally closed by a latch shaft rotary handle; another group as an emergency locking device, which functions when the impact force greater than 294N, the moment, the door and the door frame closed, the compression seal ring, lock into the lock cylinder, toggle double leaf springs, brake lock, preventing the door rebound; toggle key lever to release the lock outside. 4, next page dumplings way thrust ball bearings used in the middle with spring folding, make sure the door closed automatically. 5, the sealing method using the "9"-shaped cross-section rubber seal. Mine explosion-proof anti-shock valve Technical Data Drawing No. Frame Dimensions (mm) Pressure (kPa) ventilation rate (m3 / h) T86-FH2500/918 9001800 2500 6000 T86-FH1500/918 9001800 1500 6000 |
