Low temperature valves include low -temperature ball valves, low -temperature gates valve, low temperature intercept valve, low temperature safety valve, low temperature stop return valve, low temperature butterfly valve, low temperature stream valve, low temperature pressure reducing valve, etc., mainly used for ethylene, liquefied natural gas device, natural gas, natural gas, natural gasLPG LNG storage tanks, accepting bases and satellite stations, empty equipment, petrochemical tail gas separation equipment, liquid oxygen, liquid nitrogen, liquid cymbal, carbon dioxide low temperature storage tank and slot car, transformer oxygen and other devices.
Low temperature valve installation
The installation skills and precautions of the low temperature valve are first. The low -temperature valve is often used to control which medium that is harmful to the human body.Therefore, it is necessary to ensure that the valves gas is good, and the parts of the valve should not be loose or lacked during installation, and the test of intensity and accuracy, sealing and leakage should be performed.Second, before installation, the low temperature valve should be cleaned to the pipeline and valve to remove impurities and oil. It can also be performed according to the cleanliness requirements proposed by the user, and then some lubricants are added to the low temperature valve, but pay attention to the taboos of the working medium.To avoid accidents.
Low temperature valve standard
The standards are based on the following points: 1. The tube valve should be selected on the pipeline or device of high temperature and high -pressure media.Such as thermal power plants, nuclear power plants, high temperature and high -voltage tube roads.2. On the pipeline on the pipeline, the pipelines that are not strict with flow resistance.That is, there is not much consideration for pressure loss.3. Small valves can choose needles, instrument valves, sample valves, pressure meter valves, etc.4. There are traffic adjustment or pressure regulation, but the requirements for adjustment accuracy are not high, and the diameter of the pipeline is relatively small.5. Small chemical fertilizer and large chemical fertilizer in the synthetic industrial production should be selected from the nominal pressure PN160 nominal pressure 16MPa or PN320 nickname pressure 32MPa high -pressure angle intercept valve or high -pressure angle -type throttling valve.
