ZZDQ nitrogen sealing device (nitrogen sealing valve)
Product Introduction
ZZDQ nitrogen sealing device (nitrogen sealing valve) 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 in the container and air, prevent material volatilization, oxidation, and ensure the safety of the container. 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.
Product Features
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, and can be operated 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 low friction, responds quickly, and has high control accuracy;
The nitrogen supply device adopts a commander operation, 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.
