Ammonia globe valve should avoid impact vibration, Do not mix corrosive substances.
It should also be noted that special ammonia valves are generally not used for other gases.To prevent misuse, some ammonia valves have special connections to cylinders.For example, hydrogen and propane both use left thread, also known as reverse thread, should pay special attention to installation.
Other tips:
The high pressure chamber of the ammonia valve is connected to the cylinder. The low pressure chamber is the gas outlet and leads to the service system.The high pressure gauge indicates the pressure at which gas is stored in the cylinder.The outlet pressure of the low pressure gauge can be controlled by the adjusting screw.
When in use, first open the cylinder master switch, and then clockwise rotation of the low pressure gauge pressure adjustment screw, make it compress the main spring and drive the film, spring pad block and the top rod to open the valve.Such imported high-pressure gas enters into the low-pressure chamber through throttling and decompression from the high-pressure chamber and leads to the working system through the outlet.Turn the adjusting screw to change the opening height of the valve, so as to adjust the flow of high-pressure gas and achieve the required pressure value.
Ammonia globe valves are equipped with safety valves.It is the device to protect the ammonia pressure reducing valve and make it safe to use.If the outlet pressure rises by itself and exceeds a certain allowable value due to valve pad, valve damage or other causes, the relief valve will automatically open to vent.
