Low temperature regulating pneumatic valve installed

low temperature regulating pneumatic valve temperature below - refers to the media - - ℃ of pneumatic regulating pneumatic valve or electric pneumatic valve, because of the extremely low temperature, low temperature so adjust the use and installation of pneumatic valve and normal temperature and high temperature regulating pneumatic valve has some differences, must be properly installed, to ensure that no problems in use process, the main points of the need to pay attention to the following:
. Check whether the whole pneumatic valve parts defect and loose. Medium on the use of harmful to human body health, must carry out strength, sealing, leakage and accuracy of the test.
. Before installation of pipeline cleaning with pneumatic valve, remove impurity and oil. Especially the oil situation, the user may request the purity of the concrete. Selection of lubricant, working medium must be considered taboo, avoid the happening of the accident.
. Pneumatic valve and pipeline flange connection, should pay attention to alignment. Pneumatic valve cover are installed on the flange connection between plate and cold box adopts flexible connection as much as possible.
. Installation site should consider the safety of the personnel and equipment, convenient for operation, and for disassembling and maintenance.
　. Pneumatic valve should stand, vertical installed in horizontal pipe runs, when necessary, can tilt installation, pneumatic valve from vertical or have a larger vibration occasions, must use fixed support frame.
. Medium flow direction should be consistent with pneumatic arrow on the body pointing in the direction. Air should be dry, no oil. Pneumatic valve should be in the environmental temperature - ~ ℃ between use.
. In order to make the pneumatic valve control system failure or overhaul still can continuous production, the bypass should be set up. The bypass flow rate characteristics of pneumatic valve and trip to consistent with the original pneumatic valve selection.
