Description
Technical field
The invention belongs to and use pipe fitting equipment technical field, be specifically related to noise reduction rotary flow type PVC flow guide device.
Background technique
PVC is very fast in China's PVC development in recent years, and annual growth rate reaches 8%, and the annual growth rate of demand 2%.In plastic tube, PVC consumption holds a safe lead always, it is widely used in water supply and sewerage pipeline, because current Plastics in China pipe production ability reaches 3,000,000 tons, mainly contain PVC, PE and PP-R pipeline three major types, wherein PVC pipeline is the maximum plastic pipe of the market share, accounts for the share of plastic pipe nearly 70%.
Because PVC has the following advantages: 1, light weight, handling and loading is convenient, carrying, convenient construction, can save artificial.2, chemical proofing is excellent, and pvc pipe has acidproof, alkaline-resisting, the corrosion resistance of friendship, and the use for chemical industry is very suitable.3, fluid resistance is little, and the wall of pvc pipe is smooth, and the resistance of convection cell is little, and its roughness coefficient is only 0.009, is low compared with other tubing, and under identical flow, caliber can give and reducing.4, mechanical strength is large, the water pressure resistance intensity of pvc pipe, proof to external pressure intensity, and impact strength etc. are all very good, are applicable to the piping engineering of various condition.5, electric insulating quality is good, and pvc pipe is rich in superior electrical apparatus insulation, is applicable to the conduit of electric wire, cable, with architectural electric wire pipe arrangement.6, do not affect water quality, pvc pipe is confirmed not affect water quality by solubility test, is the best tubing of current running water tube.So PVC use is quite extensive at present.
Along with modernization industry and urban construction accelerate, the inhabitation of people and the environment of work day by day noisy, had a strong impact on our work and have a rest, high level and small sized multiple story building water vent unexceptional.The plastic pipe manufacturer that current China has also releases one after another some noise reductions and quiet plastic drain pipe, wall spiral hush pipe as real in 2U-PVC, 3U-PVC hollow wall spiral hush pipe, 4MPP mute pipe etc.; But all, all there is more or less not part in some unsatisfactory place, and the space had much room for improvement is very large.The real wall spiral hush pipe of 2U-PVC and 3U-PVC hollow wall spiral hush pipe carry out noise reduction mainly through the spiral bar of its inwall, but due to spiral bar limited height, water displacement is large, still very large noise is produced when current fall rapidly, therefore need to carry out sound insulation by additional layer, what the real wall spiral hush pipe of 2U-PVC adopted is that U-PVC layer carries out sound insulation, and its soundproof effect is poor, therefore, still can affect indoors artificial to do, learn, have a rest.3U-PVC hollow wall spiral hush pipe is then that the hollow layer formed between inwall and outer wall carries out sound insulation, its soundproof effect is slightly better than the real wall spiral hush pipe of 2U-PVC, but in order to form hollow layer, be connected by several or ten several muscle between outer wall with inwall, during tube forming connecting tendon place and outer wall other locate to shrink inconsistent, the stress that outer wall produces at connecting tendon place is larger, its physical and mechanical properties is very low, especially erosion-resisting characteristics, connecting tendon easily splits from root, and therefore the mechanical property of 3U-PVC hollow wall spiral hush pipe is bad.Although its soundproof effect of 4MPP mute pipe is good, be subject to the restriction of material property itself, the equal existing defects of cost, outward appearance and aging quality resistance.
