Non-return valve for gravity pipeline and method for regulation of water inflow in the gravity pipeline network

摘要

The purpose of the notification is the gravitational sewage return valve and the way the water flow in the gravitational sewage network is regulated. The reversible gravity drainage valve is characterised by being equipped with an extension (1) of the pipe outlet (R),an extension of the outlet to the rainwater inlet or sewage well, extending at least one basket, with at least one basket, under the length (1), at least one closing swimmer (3) and/or a non-propelled body (3a) moving. The size of the closing floater (3) and/or non-resistant body (3a) in the cross section is greater than the diameter of the inner tube outlet (R). In addition, the valve contains a guided motion over a closing floater (3) or a non-resistant body (3a),at least one pusher (5),which is located within at least one basket over a length (1). At least the shoulders of the basket comprising the closing float (3) and/or the non-propelled body (3) are a moving element whose trajectory is transmitted by the motion of the pushing float (5).
