Description

Technical Field

[0001] This utility model belongs to the field of flange gate valve technology, specifically a flange gate valve. Background Technology

[0002] The flow or cut-off of media in a pipeline is controlled by raising and lowering a gate. When the gate is fully raised, the media can pass freely; when the gate is fully closed, the flow of media is blocked. This method is commonly used in pipeline systems that require complete opening or closing.

[0003] When pipelines require maintenance, equipment replacement, or pressure testing, closing the flange gate valve can isolate the pipeline section to be treated from other parts, prevent media leakage, ensure operational safety, and prevent backflow of media when used in conjunction with other equipment.

[0004] After prolonged use, it was found that traditional flange gate valves have the risk of accidental activation, leading to unstable opening and closing. Furthermore, when facing unconventional installation positions, it is not easy to adjust the direction of the mounting bracket, which affects the installation of flange gate valves.

[0005] Therefore, this utility model provides a flange gate valve. Utility Model Content

Through the above structure, the docking assembly allows the handwheel rod and the gate plate to be connected, facilitating the handwheel rod's opening and closing control of the gate plate.

Through the above structure, the control component can control the rotation of the threaded rod, and the spreading plate, which slides forward, separates and spreads the docking groove and the docking block, releasing the docking stability, avoiding accidental contact, and further enhancing the protective separation effect of the flange gate valve.

[0010] Preferably, an adjusting groove ring is installed on the outer side wall of the flange gate valve body; an adjusting rod is slidably fitted on the inner side wall of the adjusting groove ring; and an installation plate is fixedly connected to the end of the adjusting rod. Through the above structure, the adjusting groove ring and the adjusting rod can rotate and adjust the installation direction of the installation plate, which facilitates installation in various positions and further enhances the installation and adjustment effect of the flange gate valve.

[0013] Preferably, the surface of the expansion plate is coated with an anti-corrosion coating; through the above structure, the anti-corrosion coating can extend the service life of the expansion plate in a humid environment, further enhancing the durability of the flange gate valve.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. The flange gate valve of this utility model can connect the handwheel rod and the gate through the setting of the docking assembly, so as to facilitate the opening and closing control of the gate by the handwheel rod.
