Embodiment
Below preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the utility model, and be not used in restriction the utility model.
As shown in Figure 1, the drainage pipe 1 of water heater is arranged on the Water pipe bracket 3 of water heater 2.Figure comprises shunt 14, intake pipe 10, waste pipe 11, drain valve 12, Water pipe bracket 3.
The outward appearance of existing drainage pipe and schematic cross-section are as shown in Figures 2 and 3.
Fig. 4 shows the schematic cross-section of the frost-cracking-preventing drainage pipe that the utility model embodiment provides.Wherein, frost-cracking-preventing drainage pipe 1 comprises waste pipe 11 and drain valve 12.Shown in composition graphs 1, can find out, whole drainage pipe 1 is fixed on the Water pipe bracket 3 of water heater 2 via drain valve 12 entirety.Drain valve 12 is provided with weep hole 121.
As shown in Figure 4, be different from the existing drainage pipe shown in Fig. 3, the frost-cracking-preventing drainage pipe that the utility model embodiment provides is double-skin duct structure, comprises outer layer pipe 101 and inner layer pipe 102, described outer layer pipe 101 and inner layer pipe 102 fit tightly, and form a kind of concentric pipe structure.
The frost-cracking-preventing drainage pipe that the utility model embodiment provides preferably makes outer layer pipe with metallic material.Described metallic material can use steel pipe, aluminium sheet, copper material or aluminum foil plate conventional in prior art, but does not get rid of the possibility using other materials.As long as within the utility model concept, meet model utility object of the present utility model, any other material can be used to make outer layer pipe.
The frost-cracking-preventing drainage pipe that the utility model embodiment provides preferably makes inner layer pipe with cellular plastic.The schematic diagram of cellular plastic as shown in Figure 5.In cellular plastic, comprise countless micropores 111 and entity part 112.Also it is contemplated that and use other materials with high elasticity and toughness to make inner layer pipe.
The maximum feature of described cellular plastic is that abscess is small and dense.Cellular plastic pipeline has very strong shock resistance and toughness because of the existence of micropore, rebound elasticity is high.When ambient temperature is lower than the water condensation Cheng Bing in drainage pipe when 0 DEG C, volume expands, certain pressure is caused to metallic material waste pipe inwall, the cellular plastic pipeline that now the strong rebound elasticity of toughness is high plays compressible function, cushion the extruding force that volumetric expansion causes metallic material drainage pipe inwall significantly, effectively prevent drainage pipe that the phenomenon of bursting by freezing occurs under worst cold case.
