According to the work of a low pressure vacuum valves, ultra high vacuum valves and vacuum valves. 根据工作压力有低真空阀门、高真空(HV)阀门和超高真空(HV)阀门。
Leakage and degassing rate is an important parameter to evaluate the performance of high vacuum multi-layer insulated dewar. 漏放气速率是评价高真空(HV)多层绝热杜瓦性能的一个重要指标。
Use self-designed pump system to meet requirements of high-speed of air exhaust and high vacuum during frying. 采用自主设计的真空系统,保证了油炸过程的大抽气速度和高真空(HV)的要求。
Very importantly, there is a vacuum chamber with high vacuum pumps and electronics to run the mass spectrometer. 拥有真空泵和电子装置的真空室质谱仪运行中重要组成部分。
GD high vacuum flapper valve is used to put through or cut off the airflow in vacuum pipeline. GD型高真空(HV)挡板阀用于接通或切断真空管路中的气流。
