| titleOfInvention | Dual backflow check valve, vacuum sewage system and method of preventing fluid backflow |
| abstract | A dual backflow check valve for use in a vacuum sewage system, wherein the check valve includes a vlave body and a vlave flap pivotally mounted inside the valve body, the vlave body having a primary (branch) conduit and a secondary (service) conduit entering the primary conduit at an acute angle. The primary conduit has an upstream portion forming a primary inlet into the valve body and a downstream portion forming a primary outlet out of the vlave body, and the secondary conduit forms a secondary inlet into the valve body. The valve flap is pivotable between two positions, a first position in which it prevents fluid from entering the secondary conduit and a second position in which it prevents fluid from entering the upstream portion of the primary conduit. Preferably, the primary conduit and the secondary conduit of the check valve are oriented in a substantially horizontal plane in the vacuum sewage system. |
