The Vacuum Breaker Valve is installed above the hump (elevation point) of the siphon type water pipeline, and acts as a quick gate on the siphon type outlet pipe. Vacuum breaking valve is installed in ordinary positive pressure water pipelines. When negative pressure occurs in the pipeline, the valve is opened to suck in air and break the vacuum degree, protecting the pipeline from being sucked in and compressed

Installation precautions |
| A vacuum breaker valve is a safety valve. Mainly used in containers or pipelines, this valve can automatically open when negative pressure or vacuum gradually increases due to system operation or shutdown, breaking the vacuum effect and preventing pipelines and other equipment from collapsing, cracking, and other phenomena to protect equipment safety | To ensure that the vacuum breaking valve meets the design and usage requirements, it is necessary to inspect and maintain it every six months. Open the upper cover and check if the negative pressure plate moves flexibly, if there is any obstruction or deformation. When reinstalling the pressure plate, ensure that the contact surface is tight and the guide rod is flexible. Is the operating pressure within normal range | 1. The vacuum valve must be installed on the connecting flange above the container, and the flange connection parameters are generally executed according to the national standard GB4216.4. 2. The connection between the valve and the main pipeline flange must be equipped with a sealing gasket and the bolts must be tightened. 3. The installation direction of the valve should be in a location that is easy to operate for manual emergency opening, and there should be no obstacles on both sides. 4. After installation, the dust cover of the vacuum valve should be removed. |
