(1) according to different requirements, ammonia valve has many specifications. Most of the maximum inlet pressure, the minimum inlet pressure of not less than the outlet pressure of 2.5 times. Outlet pressure specification more generally, the maximum outlet pressure.
(2) ammonia valve should be installed to determine whether the specifications of its connection with the use of the connector system is consistent. Ammonia with the use of hemispherical valve connection, tighten the nut so that by the two fit together. Therefore, the use of the two hemispheres should be kept clean surface to ensure good air tightness results. High pressure gas before installation can blow dust. If necessary, can also be used to make Teflon and other gasket materials.
(3) Ammonia valve should be prohibited access to oil, to avoid fire accidents.
(4) is stopped, the valve should be put in the air over the net, then loosen the adjustment screw so as to avoid long-term compressive deformation of the elastic element.
(5) ammonia should avoid impact with the valve vibration, not in contact with corrosive substances. These cut-off valve with the use of ammonia and precautions with the same cut-off valve with ammonia. However, it should be noted: special ammonia valve is generally not used for other gases. In order to prevent misuse, and some ammonia between the valve and the cylinder using a special connector. For example, hydrogen and propane are used thread left teeth, also known as reverse thread, installation should pay special attention.
