Description

Technical Field

[0001] The utility model relates to the technical field of water pipe exhaust devices, in particular to an exhaust device for a water supply pipe network. Background Art

[0002] As we all know, the pipeline system for delivering and distributing water to users in the water supply network water supply project is composed of pipelines, accessories and auxiliary facilities. The auxiliary facilities include regulating structures (tanks, water towers or water columns) and water supply pumping stations.

[0003] A valve that can automatically exhaust air in a water supply pipe. It is installed vertically on the top of the pipe. When the pipe is filled with water, the air in the pipe can be discharged through the exhaust port. After it is filled with water, the float (usually a floating ball) closes the exhaust port under the action of buoyancy to prevent the discharge of water. When the pipe is drained, the float drops with the water level in the pipe, the exhaust port opens, and air enters the pipe to prevent the formation of a vacuum in the pipe.

[0004] Exhaust devices are now equipped with air vents on top, and the air vents are all horizontally vented outward, so that the gas in the pipeline can be discharged. However, the following problems still exist: First, when maintenance personnel inspect the exhaust device, the gas in the pipeline passes through the air vent with a high pressure, which may easily injure the maintenance personnel; second, the air vents on the exhaust device are all exposed in the ground well. After being used for a long time, dirt will remain in the air vents. When the water supply to the pipeline is stopped, the dirt will be easily sucked into the pipeline when air is inhaled, causing water pollution.

[0005] Therefore, we designed a water supply network exhaust device to solve the above problems. Utility Model Content
