SSG200 型系列消防水鹤也称多功能消防给水栓(国外英文资料) Throughput: 0.1 m3 / S. The turning radius of the outlet: R = 2500mm. For the turning Angle of outlet: a = 360 ° Interface flange: DN200 (gb91195-88), flange diameter 335mm. High ground: 3.8 m. Hole center distance 295 mm, aperture Φ 22, hole number 8. Installation USES relevant requirements: Should be installed in the open road, make the fire fighting vehicle have the leeway. The crane should be installed in the 100m-1000mm diameter and the pressure is on the 2.5kg water supply line, the amount of water will be about 10T/min. The product has automatic backwater device, installed in the bottom of the well cover, open the shaft of the shaft to start work, the work is finished cover the well cover, the water is automatically discharged. The ground is equipped with fire hydrant and manual rotating device. Fire crane structure diagram Feed water, rapid drain part This is when the fire truck is supplying water, opening the water valve and starting to feed the water. Completed water, turn off the water valve, stop water supply, drain off the riser at the same time more than water (for water supply valve of the above water riser in the water supply has been completed, and part of the remaining water. If the fire water crane is used below freezing conditions, over this part of the water freezes easily bilge bad riser, for will more rapidly in water after the water drainage in the base of fire water crane negative well below). ? We currently used by fire water crane, is closed at the end of the fire water supply water supply valve, open the drain valve and drain (most of the drainage is to open fire water crane covers first, then close the drain valve well, operate up more troublesome, sometimes easy to forget drainage, once forget, consequences). In order to optimize the operation link, reduce the unnecessary loss, in the design of fire water crane structure, had better water supply and drainage design a two functions or as one of the foot
