According to the conditions of use, the design of cryogenic valves has the following requirements:
1.The valve should not be a significant heat source for the cryogenic system. This is because the inflow of heat not only reduces the thermal efficiency, but if the inflow is too much, the internal fluid will evaporate rapidly, causing abnormal pressure rise and causing danger.
2.The low temperature medium should not have a harmful effect on the operation of the hand wheel and the performance of the packing seal.
3.The valve assembly directly in contact with the cryogenic medium should have an explosion-proof and fire-proof structure.
4.The valve assembly working at low temperature cannot be lubricated, so structural measures need to be taken to prevent the friction parts from scratching.
1. The storage of the valve should be noted, and it should be stored in a dry and ventilated room, and obstruct the two ends of the passage.
2. The valve should be inspected regularly, and the dirt on it should be removed, and anti-rust oil should be applied to its surface.
3. The valve after installation should be constructed on schedule to ensure its normal handling.
4. Check whether the sealing surface of the valve is worn or not, and carry out maintenance or replacement according to the condition.
5. Check the wear condition of the trapezoidal thread of the valve stem and the valve stem nut, whether the packing is obsolete, etc., and carry out the necessary replacement.
6. Check the sealing instinct of the valve to ensure its instinct.
7. The valve in operation should be in perfect condition, the bolts on the flange and the bracket are complete, the threads are not damaged, and the situation is not loose.
8. If the handwheel is lost, it should be equipped immediately instead of replacing it with an adjustable wrench.
9. The packing gland does not allow tilting and probably no pre-tightening interval.
10. If the valve is used in a relatively despicable condition and is easily contaminated by rain, snow, dust, sand and other dirt, it should be a protective cover for the valve stem.
11. The ruler on the valve should be complete, accurate and clear, and the valve should be sealed and capped.
12. The insulation jacket should be free of dents and cracks.
13. Valves in operation, avoid knocking on them, or support sunken objects.
