Description

Technical Field

[0001] This utility model belongs to the technical field of ash valve equipment, specifically, it relates to an ash blind plate valve. Background Technology

[0002] A blind flange valve is a valve device specifically designed for ash conveying systems, primarily used to cut off or connect ash media in pipelines.

[0003] The prior art discloses a blind flange valve (CN219139868U). The blind flange valve body has an internal heat preservation mechanism that extends to the outside of the valve body. The heat preservation mechanism includes a port body and a blind flange body, both located inside the valve body. The port body and the blind flange body are connected to the valve body via a connecting frame. A heating wire is fixedly embedded inside the blind flange body in a spiral arrangement. A baffle is provided inside the blind flange body, and the baffle is movably connected to the blind flange body via a hinge. A rubber sealing ring is fixedly fitted to the outside of the baffle. The heating wire is energized and heated by a switch seat. Because the heating wire is spirally wound inside the blind flange body, it can contact the blind flange body with the largest possible area, making the heating efficiency of the blind flange body faster. At this time, both the surface of the blind flange body and the surface of the baffle can be uniformly heated. Through the above structure, the solidification of viscous liquid in the blind flange valve can be reduced in the closed state.

[0004] The search revealed that existing technologies lack automatic locking mechanisms, which makes the opening and closing of the device more complicated, especially in high-pressure and high-temperature environments. Operators need to spend more time and effort, and due to the relatively complicated operation, gaps are easily left during the locking process, resulting in incomplete sealing. With long-term use, the seals are easily worn by friction from ash and slag, leading to a decrease in sealing performance and leakage.

[0005] In view of this, this utility model is hereby proposed. Utility Model Content
