Description

M-shaped ventilation pipe fitting

Technical Field

The utility model relates to the technical field of pipeline connection, in particular to an M-shaped ventilation pipe fitting.

Background

In the setting and installation of a building drainage system riser, in order to save installation space, an M-shaped ventilation pipe fitting is usually adopted for the communication of the drainage riser and the ventilation riser. However, the vent hole on the drain pipe section of the current M-shaped vent pipe fitting is easily blocked by a water curtain, so that the air in the drain riser cannot be discharged through the vent riser in time, and the drainage quantity is affected. In addition, the current M-shaped ventilation pipe fitting has no maintenance function, and can be connected with an independent vertical pipe with an maintenance hole, so that the construction difficulty and the cost are increased.

At present, an improved type H ventilation pipe fitting is disclosed in Chinese patent publication No. CN214222360U, and the pipe fitting solves the problem that a water curtain influences the drainage amount, but the patent also has the problem that the pipe fitting cannot be overhauled. The water curtain is guided to a position far away from the air vent by the baffle edge, so that the water curtain is prevented from blocking the air vent, the purpose of the water curtain is to unblock an air channel, the energy dissipation effect is small, and the water flow falling down from the wall at a high position has a high speed.
