What is the discharge valve? What are its capabilities and uses?
Corrosion resistance: 1. Use water, acetone, alcohol, ammonia, barium benzoate, barium benzoate, barium benzoate and other media (WCB material temperature use -29℃-425℃). 2. The use of particles, oil, pulp, carbon dioxide gas and other media (stainless steel can be used temperature -600℃-232℃). 3. Fluorine-containing ionic liquid (such as fluorine-containing ionic liquid HF strong base and phosphoric acid (temperature less than 15000℃, concentration & GT; 30%). 4. The general working temperature of stainless steel is less than 150℃, the pressure range is 0.6-2.5mpa, more than the provisions of the order should be stated.
Key points of construction and installation
1) The installation position, height and inlet and outlet direction must meet the design requirements, and the connection must be firm and tight.
2), all kinds of manual valves are installed on the insulation pipeline, the handle shall not be downward.
3) The appearance of the valve must be checked before installation, and the valve nameplate should comply with the provisions of the current national standard "General Valve Mark" GB12220. The working pressure is greater than 1.0mpa and the valve is cut off on the main pipe. The strength and tightness test should be carried out before installation and qualified before use. In the strength test, the test pressure is 1. The duration is not less than 5 times min, the valve body and packing should have no leakage, qualified. Tightness test, the test pressure is 1.1 times the nominal pressure; The test pressure shall meet the test duration GB50243 standard requirements of the disc sealing surface without leakage.
