Angle ammonia shut-off valve

【Introduction to Angle Ammonia Stop Valve】

J42B angle typeAmmonia shut-off valves, abbreviated as ammonia valves, often use gases such as oxygen, nitrogen, hydrogen, argon, etc. These gases are usually stored in dedicated high-pressure gases. When in use, the gas pressure is reduced to the required range for the experiment through an ammonia shut-off valve, and then finely adjusted through other control valves to input the gas into the system. The most commonly used pressure reducing valve is the ammonia shut-off valve, abbreviated as ammonia valve.

【Instructions for using globe valves for angular ammonia】
(1) There are many specifications for ammonia pressure reducing valves according to different usage requirements. The maximum import pressure is mostly, and the minimum import pressure is not less than 2.5 times the export pressure. There are many specifications for export pressure, generally, with a maximum export pressure of.
(2) When installing an ammonia pressure reducing valve, it should be determined whether its connection specifications are consistent with the joints of the system being used. The ammonia shut-off valve adopts a hemispherical connection, and the two are fully matched by tightening the nut. Therefore, both hemispheres should be kept smooth during use to ensure good airtightness. Before installation, high-pressure gas can be used to blow away dust. If necessary, materials such as polytetrafluoroethylene can also be used as gaskets.
(3) Angle ammonia shut-off valves should be strictly prohibited from coming into contact with grease to avoid fire accidents.
(4) When stopping work, the residual air in the pressure reducing valve should be released completely, and then the adjusting screw should be loosened to prevent the elastic element from being deformed under long-term pressure.
(5)Angle ammonia shut-off valveAvoid impact vibration and do not come into contact with corrosive substances. The usage method and precautions of these ammonia shut-off valves are basically the same as those of ammonia shut-off valves. However, it should also be pointed out that specialized ammonia valves are generally not used for other gases. To prevent misuse, some ammonia valves use special connection ports between them and steel cylinders. For example, both hydrogen and propane use left threaded threads, also known as reverse threads, and special attention should be paid during installation.
