Anti-shock Wave Door Application
Anti-shock Wave Door is used in underground, the resistance to blast, the required air volume adjustment warehouse and isolation effect.
It includes door frames, doors, locking device, dumplings pages and other components.
It includes door frames, doors, locking device, dumplings pages and other components.
Anti-shock Wave Door Main Structure
1、The frame range of edge horn compound frame structure.
2、Door leaf valve device, the upper is equipped with three sets of ventilation in the valve plate to open three group a total of 18 hole diameter of 122 mm, live door outside is equipped with automatic open 12 degrees Angle of valve plate.Each group valve ventilation volume is 2000 cubic meters/h, total air volume is 6000 cubic meters/h, wind speed according to 8 m/s to carry on the design, make it according to the underground blasting material need air volume and total return air duct negative pressure value, determine the ventilation valve group number, and the adjustable valve hanging plate in each group of fine-tuning Zhang Qi Angle, in order to meet the best ventilation rate.When the rolls once something unexpected happens, a shock wave attenuation, pressure as long as more than 20 kpa, live door hanging plate compression and then shut down automatically within 3-8 s, isolation with the outside world, protection, through the total return air duct.
3、,Lock set two groups, one group is usually closed using the locking shaft and rotates type; Another group of emergency locking device, its function is when the impact is greater than 294 n, instant, the cry shot right up to the door with the door closed, the compression sealing ring, locks into the lock, toggle the double leaf spring, brake atresia, prevent door rebound; Upon the key handle can remove atresia.
4、Dumplings page using one-way thrust ball bearings, intermediate use spring folding, ensure that the door shut automatically.
5、Sealing method using "9"-shaped cross-section rubber seal.
