Mechanism of industrial cold water cooling system in the pneumatic valve installation method

in the refrigeration system of industrial cold water machine, pneumatic valve is used to control the refrigerant flow rate and the main function of direction, in daily use, also need to often use to pneumatic valve, when the industrial cold water machine downtime or is open, need to use pneumatic valves. Because of its daily use frequency is taller, so at the time of installation and need more attention, in order to ensure the normal use of it, and will not affect the use of industrial cold water machine is stable. Refrigeration letters below small make up take you to understand the mechanism of industrial cold water cooling system in the pneumatic valve installation steps and matters needing attention.
, should put pneumatic valves where the easy disassembly and maintenance, all kinds of pneumatic valve installation must pay attention to the flow of refrigerant, not backward.
and in cold water for industry mounting flange pneumatic valve, flange and a pneumatic valve flange must be done with high-pressure asbestos plate mat, high-pressure asbestos plate thickness according to the pneumatic valve flange groove depth is determined. When the pneumatic valve and groove deeper, want to use thicker asbestos board, avoid the bump interface is easy to have a gap between them and the untight seal. In the assembly pneumatic valve, flange bolts must do all force uniform, otherwise, concave and convex interface is easy to partial pressure.
and installed by the pneumatic valve, should make the working medium flowing from the pneumatic valve at the bottom of the upper. Install on the road in a horizontal pipe, pneumatic valve rod should be vertical or inclined one point of view, to ban pneumatic valve lever down. If the pneumatic valve position inaccessible or position is higher, for the sake of convenient operation, can install the pneumatic valve stem level.
, to industrial cold water machine installation check pneumatic valve, pneumatic valve core to ensure to open automatically. For aerodynamic lift check valve, shall ensure that the center line of the pneumatic valve core and the horizontal plane perpendicular to each other. For swing check pneumatic valve, shall ensure that the rotation of the pneumatic valve core board, and pneumatic valve core board must be put into a level.
the pneumatic valve should be installed directly in the equipment, safety exit by the pneumatic valve, pneumatic shall conform to the working medium flowing direction of arrow on valve body.
, electromagnetic air valve must be installed level, at the exit to the equipment must be stipulated in the design the location of the installation. If a solenoid pneumatic valve installed in front of the pneumatic valve throttle, at least keep the mm spacing between them.
and thermal expansion of industrial cold water machine pneumatic valve must be installed level also, pay attention to the pneumatic valve inlet and outlet connection, usually in pneumatic valve inlet side has a mesh. If make the thermal expansion of pneumatic valve has good control and the position of the heat pack is very important. Thermal package should be firmly fixed on the clean air suction pipe, let the heat pack have good contact with the suction pipe. Outer balance external balance pipe thermal expansion pneumatic valve should be installed in the muffler thermal colligation in the lower part of the package, and thermal bag binding distance for ~ mm, thermal bag shall be binding on the horizontal section, external balance tube should be back to the trachea horizontal section at the top of the pick up.
