Description

Technical Field

[0002] The main function of soft-seal gate valves is to control the flow of fluid in various industrial and water supply and drainage systems, achieving a zero-leakage sealing effect.

[0003] For example, a soft-seal gate valve with announcement number "CN219062587U" is designed for easy replacement. It uses a filter screen to block impurities in the water inside the pipeline, preventing them from entering the valve body and accumulating on the gate plate, causing corrosion and damage. The filter screen is easily installed and removed using locking blocks and connecting blocks, allowing workers to clean the filter screen while simultaneously cleaning the blocked impurities in the pipeline, thus preventing excessive accumulation. However, in the use of soft-seal gate valves, although the filter screen can filter impurities in the water and prevent clogging of the gate, it can also become clogged. When water flows through, the filter screen cannot be cleaned in time, requiring the soft-seal gate valve to be stopped, the filter screen cleaned, and then reopened. This reduces the working efficiency of the soft-seal gate valve and affects its normal use. Utility Model Content
