The filter bed composed of the asymmetric beam filtering material of the smoke and fire valve is under the solid effect of the flowing water. When the flowing water is concerned, the frictional resistance is caused. The smoke discharge fire prevention valve gradually decreases.Quick, the consolidation level of filtering materials is getting higher and higher, and the pores of smoke and fire prevention valve are getting smaller and smaller. In the direction of the flowing water, the relative density filter layer is fully automatically generated.Essence
First, the construction of smoke and fire prevention valve is very beneficial to the rapid separation of solid -state suspended solids in the water, that is, the particulate matter adsorbed by the edge of the filter bed is very easy to be captured in the filter bed in the narrow channels.The unity of speed and high precision is too concerned, improve the sewage interception of smoke and fire prevention valve filtering device, and increase the period of consideration.
Second, the key technology of the relative density of the full -automatic gradient direction of the smoke exhaust fire valve is the key technology of the use of asymmetric cortex spinal cord cord data as the filter material. One end of the smoke exhaust fire valve is a loose chemical fiber short fiber, and the chemical fiber short fiber fixation is fixed.In the large circular body with a large proportion, when you are worried, the solid core core with a large proportion of fire and fire valve brings a compressive effect on the short fiber of chemical fibers. At the same timeSmaller, the balance of balancing in the cross -sectional facial gap rate is not great, thereby enhancing the ability to intercept the smoke and fire valve filter bed.
Third, the fire -discharge fire prevention valve makes the filter bed with high pores, smaller surfaces, high filtration speed, large sewage volume, and high precision precision.When the surface layer of chemical fiber filtration materials, under the attraction of Van Dehua and the efficiency of electrical electricity, the total solid solid solid and cortical spinal cord bundle of smoke and fire prevention valve is much higher than the adhesion with quartz sand filter materials, which is beneficial to improve the speed of filtration and over -concernPrecision.
When the smoke -proof fire prevention valve is reflected, the proportion of the key to chemical fiber is poor, and the chemical fiber of the comic fiber is scattered and shaken with the anti -cleaning flow.It also increases the equipment interaction obtained by chemical fibers in the water. The irregular appearance of the filtering material causes the filtering material to rotate under the action of anti -cleaning water flow and cyclone.Cutting stress, the same effect of the same type of force on the fire prevention valve of the upper smoke discharge fire valve makes the solid particulate matter that adheres to the surface layer of the chemical fiber is very easy to fall, which in turn enhances the cleaning of the filter material.The fiber filtration material has the anti -cleaning effect of the particulate filtering material at the same time.
The above is about the manufacturing process and structural characteristics of smoking fire prevention valves. I hope it can help you. If you want to know more about more information, please pay more attention to us- ——
