摘要
螺纹锁紧环式换热器结构紧凑、耐高温、耐高压、密封性能比较可靠,作为高温高压换热器的一种结构形式,具有泄漏点少等特点,如果在运行中出现泄漏,可在不停车的情况下紧固顶紧螺栓即可达到密封要求,但是此类设备由于处于高温、高压、临氢等十分苛刻的操作环境,结构复杂,承压件多,各承压件的强度计算方法和密封结构设计均有独特之处,密封和强度设计直接影响到整个高压螺纹锁紧环换热器的安全运行,因此对其设计制造提出了更高要求,针对压螺纹锁紧环换热器特殊的结构和计算特点,从密封设计及强度计算两方面对其设计进行总结。
The threaded locking ring heat exchanger has compact structure,high temperature resistance,high pressure resistance,and reliable sealing performance.As a structural form of high temperature and high pressure heat exchanger,it has the characteristics of few leakage points.If leakage occurs during operation,The tight bolts can be tightened without stopping the machine to meet the sealing requirements.However,due to the high temperature,high pressure,hydrogen and other very harsh operating environments,such equipment has complex structure,many pressure-bearing parts,and each pressure-bearing part.The strength calculation method and the seal structure design of the seal are unique.The seal and strength design directly affects the safe operation of the entire high-pressure threaded locking ring heat exchanger,so higher requirements are put forward for its design and manufacturing.This article focuses on the pressure threaded lock The special structure and calculation characteristics of the tight-ring heat exchanger are summarized in terms of seal design and strength calculation for the designer’s reference.
