[0005] To achieve the above purpose, the present application provides the following technical scheme: a water supply network exhaust device, comprising a water supply pipe and a lifting column, the outer wall of the water supply pipe is fixedly connected with a shunt pipe at the upper end, the upper end of the shunt pipe is fixedly connected with a first flange, the upper end of the first flange is fixedly connected with a second flange through bolts, the upper end of the second flange is fixedly connected with a shell, the inner wall of the second flange is fixedly connected with a filter plate at the bottom end, the inner wall of the shell is fixedly connected with four support plates arranged in a ring array at the bottom end, the four support plates are fixedly connected with a fixed barrel, the inner wall of the fixed barrel is provided with four sliding grooves arranged in a ring array, and the bottom end of the fixed barrel is provided with a plurality of through holes arranged in a ring array, the bottom end of the lifting column is fixedly connected with a floating plate, the bottom end of the outer wall of the lifting column is fixedly connected with four sliding plates arranged in a ring array, and the upper end of the lifting column is fixedly connected with a water stop plate.

[0006] By the above scheme, by fixing and connecting the filter plate at the bottom end of the inner wall of the second flange, the device can block the small foreign matter that may fall in the water supply pipe network, prevent it from entering the inside of the exhaust device, reduce the risk of failure of the exhaust device due to blockage or damage, improve the stability and safety of the exhaust device, and through the design of the lifting column, the floating plate, the sliding plate and the water stop plate, the device can automatically exhaust according to the air pressure change in the pipe network. When water flows into the water supply pipe network, the air in the pipe network is pressed at the upper end of the pipe, the air enters the exhaust device through the shunt pipe, and when the air is exhausted, the water flows into the inside of the shell and enters the fixed barrel through the through hole.

[0013] Further, the water stop plate corresponds to the air outlet hole.

[0014] Through the above scheme, the design of the water stop plate corresponding to the air outlet hole ensures that the water stop plate can accurately open or close the air outlet hole when the lifting column moves up and down, and when the pipe network needs to be vented, the air outlet hole allows the gas to be smoothly discharged, and in the case of water pressure rising in the pipe network, the water stop plate can tightly adhere to the air outlet hole to prevent water from leaking outside the exhaust device.

[0017] Further, the floating plate is made of PVC foam material.

[0018] Through the above scheme, the PVC foam material has the characteristics of light weight, so that the floating plate can provide sufficient buoyancy, which is conducive to the lifting movement of the floating plate in the water in the pipe network, and improves the response speed of the exhaust device.

[0019] Further, the water stop plate is made of silica gel material.

[0020] Through the above scheme, the silica gel material has excellent elasticity, good weather resistance and anti-aging performance, so that the water stop plate can maintain good shape and sealing performance during long-term use, and the silica gel water stop plate can tightly adhere to the air outlet hole to form a seal and prevent water leakage.

[0021] Compared with the prior art, the technical scheme of the present application has the following beneficial effects:

[0022] The exhaust device for the water supply pipe network can block small foreign matters that may fall in the water supply pipe network and prevent them from entering the inside of the exhaust device, thereby reducing the risk of failure of the exhaust device due to blockage or damage, improving the stability and safety of the exhaust device, and enabling the device to automatically perform exhaust operation according to the air pressure change in the pipe network through the design of the lifting column, the floating plate, the sliding plate and the water stop plate. When water flows into the water supply pipe network, the air in the pipe network is pressed at the upper end of the pipe, the air enters the exhaust device through the shunt pipe, and when the air is discharged, the water flows into the shell and enters the fixed barrel through the through hole. The floating plate in the fixed barrel rises with the water level, drives the lifting column and the water stop plate to move upward, and the water stop plate can seal the exhaust device to prevent water leakage.
