Precautions for installation of cryogenic control valve
Check whether the parts of the whole valve are missing and loose. For the use of media that is harmful to human health, strength tests, sealing, leakage and accuracy must be carried out.
Before installation, clean the pipes and valves to remove impurities and grease. Especially in the case of no oil, users can put forward specific cleanliness requirements. When selecting lubricants, the taboos of the working medium must be considered to avoid accidents.
The flange connection between the valve body and the pipeline should pay attention to the coaxial. A flexible connection should be used as far as possible between the connecting plate of the mounting flange on the upper bonnet and the cold box.
The safety of personnel and equipment should be considered in the installation site, which is not only easy to operate but also conducive to disassembly and maintenance.
The valve should be installed upright and vertical on the horizontal pipeline, and can be installed obliquely if necessary. The valve must be fixed with a support frame in the case of large vertical or vibration.
The flow direction of the medium should be in the same direction as the arrow on the valve body. Airflow should be dry and oil-free. The valve should be used between the ambient temperature of -30 ~ 60 ℃.
To make continuous production when the automatic control system fails or the valve is repaired, a bypass should be set up. The flow characteristics and stroke of the bypass valve should be consistent with the original valve selection.
