AI Technical Summary

Technical Problem

[0004]该双阀板耐磨阀门在使用时通过弹簧的弹力推动密封环与阀板相互贴合，对阀门进行进一步的密闭，但长时间使用后弹簧疲劳会降低弹性，从而降低密封环与阀板之间的贴合度，进而降低密封性，为此，我们提出一种双阀板阀门

Benefits of technology

1、该双阀板阀门，通过伺服电机带动螺纹杆转动，然后带动升降板在升降槽的内部滑动，从而带动两个阀板本体升降，进而对阀体进行封闭的同时启动泵机，通过注料阀管和三通管向注油槽的内部注入水乙二醇此类物料使弹性胶套膨胀与阀板本体贴合，通过压力表可以观察弹性胶套内部的压力值，从而保证弹性胶套与阀板本体的贴合度，进而保证其密封性，同时降低阀板本体升降时与阀体摩擦，提高了该双阀板阀门的实用性。
