用铝合金、钢材,铸铁作喷灌管路,成本高,原料缺,为此,我们研究试验用塑料管路。塑料管路受温度变化影响伸缩变形大。为解决此问题我们设计了一种联接塑料管的快速接头(见图1)。试验结果表明,这种接头在气温由摄氏十几度到三十度范围内变化时,承受九十米水头的压力,伸缩自由,密封可靠。这种接头的拆装很方便,只要把塑料管头部往接头中一插即可。在此基础上,我们又解决了塑料焊接、塑料管固定等问题。直径100毫米塑料管与铸铁
With aluminum, steel, cast iron for irrigation pipelines, high cost, lack of raw materials, therefore, we study the test of plastic pipe. Plastic pipe affected by temperature changes Telescopic deformation. To solve this problem, we designed a quick connector with plastic pipe (see Figure 1). The test results show that this joint in the temperature from Celsius ten degrees to thirty degrees within the range of changes, the pressure to withstand 90 meters head, telescopic free, sealed and reliable. Disassembly of this connector is very convenient, as long as the plastic pipe to the connector in a plug can be. On this basis, we have solved the problems of plastic welding and plastic pipe fixing. 100 mm diameter plastic pipe and cast iron
