Product Description
The conventional nitrogen sealing system consists of three major parts: nitrogen supply device, nitrogen release device and safety device.
The water seal device is an innovative product designed to provide nitrogen sealing protection for various storage tanks, containers and other equipment.It integrates multiple functions such as nitrogen supply valve, water seal, nitrogen unloading, negative pressure protection, gas-liquid separator, controller, liquid level monitoring, etc,Effectively prevent the medium from contacting with air, ensuring the quality and safety of stored materials,It is widely used in the safe storage of materials in water treatment, chemical, pharmaceutical, food, petroleum and other industries.
Features
1. Accurate intelligent control: The use of reliable and stable micro-pressure device and intelligent control system can accurately reflect the nitrogen pressure in the storage tank, so that it is always kept within the set micro-positive pressure range, ensuring that the material is not contaminated by the outside air under normal operation.
2. High efficiency and energy saving: The optimized nitrogen supply system automatically starts and stops the nitrogen valve according to the changes in the tank pressure, minimizing nitrogen consumption and reducing operating costs.
3. Safe and reliable: It has multiple safety protection functions, such as overpressure discharge, underpressure nitrogen replenishment, abnormal negative pressure prevention, independent nitrogen discharge, etc. It can operate stably under various working conditions to ensure the safety of personnel and equipment.
4. Integrated design: The nitrogen inlet, nitrogen unloading, safety valve, gas-liquid separation, automatic water replenishment and other components are integrated into one, with a compact structure and easy installation, reducing the workload and time cost of on-site installation and debugging.
5. Corrosion resistance and long life: Made of high-quality corrosion-resistant materials, it can adapt to various harsh working conditions and has a long service life and low maintenance cost.

Process advantages |
No running costs |
Safe; low water consumption. | Safe; low water and electricity consumption; easy to install, no need for high-altitude work; good compatibility between nitrogen inlet valve and water seal; centralized procurement reduces risks. |
Process Disadvantages | High initial cost; Safety risks (1. When the pure water tank is full, it cannot be drained; 2. There are safety risks in the on-site discharge of nitrogen); High-quality valves are expensive, and the performance parameters of ordinary valves have large errors. |
The initial cost is high; the water seal liquid needs to be taken over; decentralized procurement may result in a mismatch between the nitrogen inlet valve and the water seal parameters. |
Need to connect to water and electricity. |
