阀门低温试验装置的节约型设计

阀门低温试验装置兼有深冷处理和低温试验的双重功能,是低温阀门生产过程中的重要设备,其冷媒和试验介质等消耗巨大且价格昂贵,对低温阀门的整机成本具有重要影响。提出了一种低温阀门试验装置的节约型设计,从组成装置的低温系统、压力试验系统和测控系统等方面着手,寻找减少消耗的途径,并重点讨论了多种高效保温技术,通过液氮喷淋实现自动调温的方式,贵重试验介质回收重复利用技术,数据采集和智能化操作模式等,提出了应从多渠道实现装置的节约型设计。

Economical design for low temperature test device of cryogenic valve

The cryogenic valve test device with subzero treatment ability and low temperature test function is the key equipment in the process of manufacturing cryogenic valve,and the consumption for refrigerant and testing medium is tremendous though they are quite expensive,which may affect the cost of the cryogenic valve.In this case an economical design of cryogenic valve test device is presented in the papers,and some resource-saving methods are explored from cryogenic system,pressure test system as well as meas...
