(Summary description)Jiangsu Belden Plastic Industry Development Co., Ltd. is a professional manufacturer of PVC drainage pipes. 　　 PVC drainage pipe noise reduction measures. 　　 People think that the noise of PVC drainage pipe is louder, which is also one of the obstacles in the promotion of this product. After testing, the noise of PVC drainage pipes at the bottom is 2 to 3 decibels larger than that of cast iron drainage pipes, which does not exceed the national standard for noise in daily life. But why do users have greater feedback on this issue? The first reason is that people are There is a process of adapting to the new environment. Building a building will amplify the sound due to the echo effect of the empty house; the second is the inadequate technical measures adopted in the design. For this reason, I believe that the first thing to do is to keep the drainage riser away from the room and living room when designing; pay special attention to the technical requirements at the junction of the riser and the bottom drainage pipe during construction. This elbow should use two 45° elbows. Connect and set up buttresses at the bottom of the riser to prevent settlement. I think that the plastic pipe buttress must be located at the lower end of the riser axis, and wrap the entire elbow to make the water flow in the riser fall to the real place, so that the impact sound is also reduced. This type of buttress not only plays a role in preventing settlement , Also has the effect of eliminating noise, of course, it is bigger than the buttress at the bottom of the cast iron drainage pipe. In order to reduce the noise of the bottom layer, some felt or rubber cushions can be put into the inner side of the holder of the bottom riser pipe to tighten properly, so as not to hinder the expansion of the riser pipe. The empty chirping of the sub-pipe. 　　 For more knowledge, please visit: http://www.baitongplastics.com
