Hi, little housekeeper this bring you control in the low temperature regulator in the installation, you need to pay attention to

Low temperature regulator refers to the medium temperature below minus 60 degrees - minus 196 degrees pneumatic control valve or electric control valve, because of the extremely low temperature, so the use of low temperature regulator and installation and normal temperature and high temperature regulator has some difference, must be properly installed, to ensure that no problems in use process, the main points of the need to pay attention to the following,

1. Check whether the valve parts defect and loose, medium on the use of harmful to human body health, must carry out strength, sealing, leakage and accuracy test,
2. Before installation of pipe and valve for cleaning, remove impurity and oil, especially the oil situation, the user may request the purity of the concrete, the selection of lubricant, working medium must be considered taboo, avoid the happening of the accident,
3. The valve and pipeline flange connection, pay attention to the alignment, the valve cover are installed on the flange connection between plate and cold box as much as possible, using the flexible connection,
4. Installation site should consider the safety of the personnel and equipment, convenient for operation, and is helpful for disassembling and maintenance,
5. The valve should stand, vertical installed in horizontal pipe runs, when necessary, can tilt installation, valve or places that have requirements of vibration, large vertical must use fixed support frame,
6. Medium flow direction should be consistent with the arrow on the body pointing in the direction of air flow should be dry, no oil, the valve should be in the environmental temperature between 30 to 60 degrees,
7. To make the automatic control system failure or repair valve still can continuous production, the bypass should be set up, the bypass valve flow characteristic and schedule to be consistent with the original valve selection,
