Second embodiment

Referring to fig. 3, 4 and 5, a liner butterfly valve with a safety alarm function according to a first embodiment of the present application is provided. The second embodiment is only the preferred mode of the first embodiment, and the implementation of the second embodiment does not affect the implementation of the first embodiment alone.

Specifically, the difference that a lining butterfly valve with safety alarm function that the second embodiment of this application provided lies in, a lining butterfly valve with safety alarm function, the bottom fixed mounting of valve body 1 has fixed column 9, the inside top of fixed column 9 and bottom all are provided with first intercommunication mouth 11 and second intercommunication mouth 10, the inside of fixed column 9 just is located the inboard fixed mounting of second intercommunication mouth 10 has control structure 12.

The control structure 12 comprises a fixing ring 121, a second connecting rod 122 is arranged inside the fixing ring 121, and a top disc 124 is fixedly mounted at the top of the second connecting rod 122.

The bottom of the second connecting rod 122 is fixedly provided with a limiting block.

A spring 123 is disposed at the bottom of the top plate 124 and on the surface of the second connecting rod 122, and leakage passage openings 125 are formed at both sides of the top plate 124.

The diameter of the first communication port 11 is smaller than that of the second communication port 10, a first rubber pad is fixedly mounted at the bottom of the first communication port 11, and a second rubber pad is fixedly mounted at the top of the top disc 124.

The bottom of the fixed column 9 is fixedly provided with a bearing box 13, and the surface of the bearing box 13 is fixedly provided with a fixed ring 14

The top fixed mounting of solid fixed ring 14 has third connecting rod 15, the top of third connecting rod 15 with the bottom fixed mounting of valve body 1.

A discharge pipe 16 is fixedly arranged at the right side of the bottom of the bearing box 13.

A valve is fixedly mounted on the surface of the drain pipe 16.

when the pressure of the liquid is large and the elastic force value of the spring 123 in the control structure 12, the liquid flows through the valve body 1, and the top plate 124 in the control structure 12 inside the fixing column 9 is pressed downwards, so that the top plate 124 moves downwards, and then the second connecting rod 122 is driven to move through the downward movement of the top plate 124, and meanwhile, the spring 123 is pressed when the top plate 124 moves, so that the spring 123 is elastically deformed, and when the top plate 124 moves downwards, the first rubber pad fixedly installed at the bottom of the first communication port 11 is enabled to be separated from the sealing state of the leakage channel port 125 formed in the top of the top plate 124, so that the liquid is enabled to flow into the bearing box 13 through the fixing column 9 and then through the leakage channel port 125, and is temporarily stored.
