Ammonia ball valve overview:
Ammonia ball valve in physical and chemical experiments, often use oxygen, nitrogen, hydrogen, argon and other gases. These gases are generally stored in special high-pressure gas cylinders. When used, the gas pressure is reduced to the required range of the experiment through the pressure reducing valve, and then fine-adjusted by other control valves, so that the gas is input into the use system. The most commonly used ammonia ball valve is referred to as ammonia gas. The appearance and working principle of
ammonia ball valve: the high pressure chamber of
ammonia valve is connected with the cylinder, and the low pressure chamber is the gas outlet and leads to the use system. The value of the high pressure meter is the pressure of the gas 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 main switch, and then clockwise turn the pressure adjusting screw of the low pressure gauge, so that it compresses the main spring and drives the film, spring pad and ejector rod to open the valve. The imported high pressure gas enters the low pressure chamber after throttling and decompression from the high pressure chamber, and leads to the working system through the outlet. Rotate the adjusting screw to change the height of the valve opening, so as to adjust the passing amount of high pressure gas and reach the required pressure value. Ammonia ball valves are equipped with safety valves. It is a device to protect the ammonia pressure reducing valve and make it safe to use, and it is also a signal device for the failure of the ammonia ball valve. If the valve pad, valve damage or due to other reasons, resulting in the outlet pressure to rise and exceed a certain allowable value, the safety valve will automatically open the exhaust. The use of
ammonia ball valve:
1, according to the different requirements of use, ammonia gas pressure reducing valve has many specifications. The maximum inlet pressure is mostly, the minimum inlet pressure is not less than 2.5 times the outlet pressure. The outlet pressure specifications are more, generally, and the maximum outlet pressure is.
2. When installing ammonia ball valves, it is necessary to determine whether the connection specifications are consistent with the joints of the system. The ball valve for ammonia is connected with a hemispherical surface, and the two are completely consistent by tightening the nut. Therefore, the two hemispheres should be kept smooth when in use to ensure a good airtight effect. High pressure gas can be used to blow away dust before installation. If necessary, materials such as polytetrafluoroethylene can also be used as washers.
3, ammonia ball valve should be strictly prohibited contact with grease, so as to avoid fire accidents.
4. When stopping work, the residual gas in the pressure reducing valve should be released, and then loosen the adjusting screw to avoid long-term pressure deformation of the elastic element.
5, ammonia ball valve should avoid impact vibration, can not be in contact with corrosive substances.
