Today, in the Jinbin workshop, a hydraulic knife gate valve with a size of DN1800 has been packaged and is now being transported to its destination. This knife gate is about to be applied to the front end of the hydroelectric generating unit in a hydropower station for maintenance purposes, redefining industry standards with its outstanding performance and spatial adaptability.

This flange knife gate valve has achieved a major breakthrough in core performance. The valve body is made of carbon steel Q355B, and the valve plate is made of stainless steel 304. It is combined with nitrile rubber sealing material, which not only achieves a zero-leakage sealing effect but also far exceeds the pressure resistance of conventional products. Cast steel knife gate valve of the same diameter can usually only withstand a strength pressure of 1.5 kilograms and a sealing pressure of 1 kilogram, while this product can withstand a strength pressure of 9 kilograms and a sealing pressure of 6 kilograms, providing a solid guarantee for maintenance operations under high-pressure conditions.

In response to the operational challenges of valves in hydropower stations, the product innovation incorporates bypass design. When traditional valves are closed, the pressure difference at both ends is large, which can easily lead to difficulties in opening. However, this design can start the bypass before opening the main valve to balance the pressure at both ends, significantly reducing the operating resistance and improving the maintenance efficiency.

What is more worthy of attention is its spatial optimization plan. Considering the limited on-site installation space for European customers, the R&D team abandoned the conventional exposed rod design and adopted a concealed rod structure, allowing the piston rod of the oil cylinder to be directly connected to the valve plate, eliminating the need for traditional brackets. This reduced the overall height of the equipment by at least 1.8 meters, perfectly adapting to compact installation environments.

The multiple innovations of this big size knife gate valve not only address the practical pain points in the maintenance of hydropower stations, but also demonstrate the precise adaptability of technical design, providing a new option for the equipment upgrade of hydropower stations.
