detailed description

The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

As shown in Fig. 1 and Fig. 2, this embodiment includes a trap main body 5, and an inspection branch pipe 8 integrally connected with the trap main body 5 is provided above the middle part of the trap main body 5, and the inspection branch pipe 8 is connected to the trap main body 5 The connection is equipped with an anti-backflow buoyancy blocking cover 3, the upper end of the anti-backflow buoyancy blocking cover 3 is connected with the lower end of a connecting rod 2, and the upper end of the connecting rod 2 is connected with a replenishing valve 9, and the replenishing valve 9 is installed in a On the water inlet pipe 1, the anti-backflow buoyancy blocking cover 3 controls the switch of the replenishment valve 9 through the connecting rod 2.

A water inlet branch pipe 16 integrally connected with the trap main body 5 is also provided on the side wall of the trap main body 5 .

A side branch pipe 12 integrally connected with the inspection branch pipe 8 is also provided on the pipe wall of the inspection branch pipe 8 . The water inlet branch pipe 16 is connected with a tee 15, and the tee 15 is connected with the side branch pipe 12 through a connecting elbow 13. Check that the upper end of branch pipe 8 links to each other with a connecting straight pipe 10, which is provided with an installation hole, water inlet pipe 1 passes through the installation hole and is installed on the connecting straight pipe 10, and the top of connecting straight pipe 10 is installed with floor drain 11.

The main body 5 of the water trap is a "V"-shaped elbow, and the two ends of the "V"-shaped elbow are respectively the water inlet end and the water discharge end. The included angle a between the drain ends refers to the included angle between the central axis of the water inlet end and the central axis of the drain end, and the included angle a can also be any other value between 35° and 135°.
