ammonia for the use of ammonia gas pressure reducing valve and ball valve method: 1, according to the different using requirements, ammonia in ammonia on both sides of the pressure reducing valve, ball valve configuration, there are many specifications. Highest ammonia pressure reducing valve inlet pressure mostly, the minimum inlet pressure not less than 2 of outlet pressure. 5 times. 2, when installing ammonia with ball valve shall determine whether the connection specification is consistent with the joint and use the system. Ammonia with ball valve adopts the half spherical connection, screw the nut on the two perfectly match. Therefore, when use should remain on the surface of the two hemispheres is bright and clean, in order to ensure a good airtight effect. Before the installation can use high pressure gas blowing dust. When necessary, can be materials such as ptfe gasket. 3, ammonia with ball valve should be forbidden contact grease, in order to avoid fire accidents. 4, stop working, the residual gas in the ammonia pressure reducing Industrial Valves should be put the net, then loosen the adjusting screw to avoid elastic element compression deformation for a long time. 5, ammonia with ball valve should avoid impact vibration, cannot be in contact with corrosive substances.
