Lianggu plugging valve delivered to the first thermal power side molten salt energy storage demonstration project in China

The 600MW (megawatt) unit steam extraction molten salt energy storage project in Hebei Province is the country's first thermal power side molten salt energy storage demonstration project. It has pioneered the technology of molten salt energy storage for thermal power extraction steam in China and opened up a new technical path for thermal power units to significantly improve their peak-shaving capacity.During the construction and maintenance of thermal power units, hydraulic testing is a critical step in ensuring pipeline safety. Ensuring the stability of the system while ensuring "once-installed, always-on" operation of these equipment is a core requirement for efficient power plant operations and maintenance.

As a technical expert in the specialty valve field, Lianggu Valve Group provided the plugging valve for this project. These valves offer:


1. Dual-function, meeting the sealing requirements of static hydrostatic testing while also enabling quick conversion to a permanent pipeline component;


2. Quick changeover: After testing, only the plugging plate needs to be replaced with the guide sleeve, significantly reducing downtime;


3. Pressure-tightening seal: Sealing performance improves with increasing media pressure, ensuring reliable operation;


4. Butt-weld connections optimize pipeline structural strength and reduce leakage risks.

Molten salt energy storage is a key technology for achieving greater flexibility in thermal power generation, and efficient, reliable valve equipment is fundamental to its stable operation. Lianggu Valve Group, positioned as a "specialty valve customization expert," continues to provide high-performance valve solutions for emerging sectors such as nuclear power, solar thermal power generation, and molten salt energy storage.
