Characteristics and USES

ZZDQ nitrogen sealing device is a self operated micro pressure control system independently developed and researched by our factory. It is mainly used to maintain a constant pressure of the protective gas (usually nitrogen) at the top of the container, to avoid direct contact between the materials inside the container and air, and to prevent material volatilization and oxidation. And the safety of the container. Specially suitable for gas seal protection systems of various large storage tanks. This product has the characteristics of energy saving, sensitive action, reliable operation, and convenient operation and maintenance. Widely used in industries such as petroleum and chemical.

characteristic

·Without the need for external energy, it can work in situations without electricity or gas, which is both convenient and energy-saving, reducing costs;

·The nitrogen sealing device is easy to set for nitrogen supply and release pressure. Can be carried out under continuous production conditions;

·The effective area of the pressure detection diaphragm is large, the set spring stiffness is small, the action is sensitive, and the device works smoothly;

·Adopting a non packing design, the valve stem experiences minimal friction, responds quickly, and has high control accuracy;

·The steel supply device is operated by a commander, with a pressure reduction ratio of up to 100:1, good pressure reduction effect, and high control accuracy;

·To ensure the safety of the storage tank, a breathing valve should be installed on the top of the tank;

·The breathing valve only serves a safety purpose, avoiding the defect of frequent opening and closing and easy damage in conventional nitrogen sealing devices.
