Examples
Referring to fig. 1 to 5, the embodiment provides an anti-overflow valve for a centralized water seal floor drain, which is arranged in a floor drain water storage part in practical application, and can realize that wastewater is discharged from the inside of the water storage part to an external drainage pipe but cannot flow back into the inside of the water storage part from the external drainage pipe, thereby playing a role in controlling the unidirectional circulation of the wastewater.
The overflow-preventing valve of the centralized water seal floor drain comprises a valve 1, a water seal core 3 and a supporting piece 2, wherein the valve 1 is arranged inside the water storage piece and is positioned at a water outlet of the water storage piece, the supporting piece 2 is arranged on the water seal core 3, the valve 1 is connected with the water seal core 3 through the supporting piece 2, the water seal effect is formed by waste water in the water storage piece, and meanwhile, the one-way circulation of the waste water is realized through the valve 1.
Further, the valve 1 is in the shape of an oblate plate, and the valve 1 is positioned at a water outlet of the water storage part and can seal the water outlet of the water storage part. Be provided with connecting piece 11 on the top of valve 1, connecting piece 11 links to each other with support piece 2, valve 1 is articulated with support piece 2 through connecting piece 11, is convenient for realize the switching of valve 1.
Further, the supporting member 2 comprises an arc-shaped plate, the edge of the arc-shaped plate is provided with an arc-shaped water outlet 21, and the valve 1 is matched with the water outlet 21 and can completely seal and isolate the water storage member and an external drainage pipeline when waste water does not need to be discharged. The edge of the valve 1 is attached to the inner wall of the water outlet of the water storage part, so that sewage and wastewater in an external drainage pipeline are prevented from flowing into the water storage part from a gap between the valve 1 and the inner wall of the water outlet. In addition, the valve 1 is located at the edge of the arc-shaped plate, preventing the valve 1 from turning over towards the inside of the water storage member. Preferably, valve 1 is the plastics material, and the rivers of being convenient for on the one hand drive its switching, and on the other hand, also be convenient for installation processing compromises economic nature simultaneously.
