L485Q焊接钢管
用生料做成的带叫生料带，可以卷成盘长期保存。使用时能自由成形，任意接头，只要一有压力，便形成一个均匀地起着密封作用的环形膜。作为阀门中阀体与阀盖间的垫圈，可在不取出阀瓣或闸板的情况下，撬开一缝隙，塞进生料带去就行了。压紧力小，不粘手，也不粘法兰面，更换十分方便。对于榫槽法兰适宜。聚四氟生料，还可做成管形和棒状，作密封用。金属空心O形圈：弹性好，压紧力小，有自紧作用，可选用多种金属材料，从而在低温、高温和强腐蚀性介质中都能适应。

由于被试件在不停地更换，必将给整个系统带来大量的污染物，而比例溢流阀对油液的清洁度要求较高。为了确保整个系统的正常运行。设计时采用了2级高压过滤。使其过滤精度达到5μm，并且采用全封闭油箱。油液的黏度受油温的影响极大，为了确保流量测试的准确，系统使用水冷却器对油温进行严格控制，使其变化范围在±2℃之内。试验台测试系统该试验台的测试参量有转速、流量、压力、温度等4个参量。转速传感器是电感式传感器，它的输出为正弦波信号，经三极管放大后，由施密特电路（493芯片），并经电阻分压，输入到反向器（411）的输入端，再由反向器的输出端接到计算机721板的G2端。
