The control valve connected to the pipeline installation
The connecting pipeline installation should pay attention to the following.
1 signal the trachea and gas supply lines commonly used brass PVC sheathed cable the diameter of sL6Xl or g18Xl
Gas supply lines should be close to the control valve.
3 signal lines and hydraulic lines should be as short as possible to shorten the signal delay and system time constant.air cylinder manufacturers
Pipeline should have sufficient the telescopic redundancy, and should not interfere with the action of the implementing agencies.
5 pipeline welding should not be welding slag off the person tube. The connecting lines should be cleaned before installation, removal of oil, water, dirt and rust. Piping connected to the pipeline should be neat and beautiful.
6 hydraulic oil pipeline should stay away from high temperature equipment and pipelines, with the hot surface distance should be greater than 150mm.
Before installation, response and pipeline connected to the drain valve, vent valve for cleaning, remove the oil, and inspection and testing.
8 hydraulic and pneumatic piping system pressure test and compliance.
Connect the signal wires, cables through pipe laying, metal hose connection on the device side. For an explosion-proof equipment should take appropriate explosion-proof measures should be taken to seal all protected system.
10 laying of the pipeline should not interfere with the maintenance of the operator's operation and maintenance personnel.
11 connection lines should be marked nameplate. Necessary, can be fixed to its support connected pipelines, prevent control valve demolition after connecting pipelines can not be fixed.
12 cable should avoid the intrusion of water and liquid immersion and corrosive or harmful gases.3 way air valve
