Safety valve: mainly used forBoiler steam generator, air compressorThe overpressure protection device; when the equipment pressure exceeds the allowable value, the valve automatically opens, then the whole amount of emissions, when the pressure is reduced to the specified value, the valve automatically closes to ensure the safe operation of equipment; the pressure range is 0.1-1.6mpa, suitable medium for steam, air, the main material for brass products.
3kwThe rated pressure of electric heating steam generator is 0.4MPA
When working normally, the indicator of the pressure gauge refers to the 0.4MPA.
Buy: 4 points, 5 kilograms (0.5MPA) is ok.
Safety valve physical map shooting:
The main connecting dimensions of the safety valve are as follows:
Nominal diameter: DN8:1. interface diameter 1/42. is suitable for medium: air, 3. pressure: can be adjusted according to customer
Nominal diameter: DN10:1. interface diameter 3/82. is suitable for medium: air, 3. pressure: can be adjusted according to customer
Nominal diameter: DN15:1. interface path 1/22. suitable medium: air, 3. pressure: can adjust according to customer
Nominal diameter: DN20:1. interface diameter 3/42. is suitable for medium: air, 3. pressure: can be adjusted according to customer
Installation and maintenance should pay attention to the following items:
All kinds of safety valves should be installed vertically. There should be no resistance at the exit of the safety valve to avoid compression. The safety valve shall be specially tested before installation and check its sealing performance. The safety valve should be checked regularly.
