波纹

Metal network hole wave packing with metal sheet metal punching, draw to mangle network block specific specification, surface its form regular rhombus network hole is then punching to become ripple a kind of packing of form, this kind of packing comprehensive silk screen packing and merit of the board wave packing , have the characteristics that light, press reducing, efficiency high.

金属网孔波填料是用金属薄板冲压、拉伸成特定规格的压延网片，其表面形成规则的菱形网孔，然后冲压成波纹形状的一种填料，这种填料综合了丝网填料与板波填料的优点，具有重量轻、压降低、效率高的特点。

The standard seats promote a low-pressure seal, using wave spring force to load the metal seat carrier toward the ball.

标准阀座采用波纹弹簧机构，将阀座推向球体，保证了良好的低压密封性能。

Broken down as follows according to material pipeline: First, tetrafluoroethylene and composite pipe: lining for tetrafluoroethylene hose, weaving between fiber entanglement for enhanced layer, the outer layer is a protective layer, good flexibility, anti-oil permeability (0.2mg / sq m), temperature reached -60 C - 200 C, resistant to acid, alkali, solvent corrosion, voltage 0.5 - 50MPa, and processing of "Teflon""PTFE bellows" and a variety of high-pressure composite pipe.

一、四氟乙烯及复合管：内层为四氟乙烯软管，中间为纤维编织缠绕增强层，外层是防护层，柔韧性好，抗油渗透性（0.2mg/平方米，耐温达-60°C--200°C，耐强酸、碱、溶剂腐蚀，耐压0.5--50MPa，并加工&铁氟龙&&四氟波纹管&及各种高压复合管。

Rectangle of corrugated cardboard, 4cm by 16cm cut with corrugations running perpendicular to the long axis of the rectangle.

矩形的瓦楞纸板， 4厘米的一十六厘米削减波纹运行与垂直于长轴的长方形。

Inner bulkheads to be stiffened by corrugations, or of flat plate stiffened vertically.

室外的舱壁应被垂直方向加强，室内舱壁应采用波纹状或垂直的平板进行加强。

The tubes are bolted to the wall with the flat steel, open side against the bin corrugations

采用扁钢将该管固定在仓壁上，使开口的一边对着波纹仓壁。

The web and flange plates with a large number of corrugations are equivalent to orthotropic curve plates and their equivalent material coefficients are obtained by stretching and shearing experiments.

为此把带有波纹的底板和腹板分别等效为正交各向异性平曲板，并通过拉伸和剪切试验得到了其两个方向的等效材料常数。

Since corrugated board itself loses about 50％ of its compression strength between 50％R.H.

因为波纹板丢失关于50 ？20of它的压缩力量在50%R.H。
